A.10.1 commit options
---------------------

These standard options are supported by `commit' (*note Common
options::, for a complete description of them):

`-l'
     Local; run only in current working directory.

`-R'
     Commit directories recursively.  This is on by default.

`-r REVISION'
     Commit to REVISION.  REVISION must be either a branch, or a
     revision on the main trunk that is higher than any existing
     revision number (*note Assigning revisions::).  You cannot commit
     to a specific revision on a branch.

   `commit' also supports these options:

`-c'
     Refuse to commit files unless the user has registered a valid edit
     on the file via `cvs edit'.  This is most useful when `commit -c'
     and `edit -c' have been placed in all `.cvsrc' files.  A commit
     can be forced anyways by either regestering an edit retroactively
     via `cvs edit' (no changes to the file will be lost) or using the
     `-f' option to commit.  Support for `commit -c' requires both
     client and a server versions 1.12.10 or greater.

`-F FILE'
     Read the log message from FILE, instead of invoking an editor.

`-f'
     Note that this is not the standard behavior of the `-f' option as
     defined in *Note Common options::.

     Force CVS to commit a new revision even if you haven't made any
     changes to the file.  As of CVS version 1.12.10, it also causes
     the `-c' option to be ignored.  If the current revision of FILE is
     1.7, then the following two commands are equivalent:

          $ cvs commit -f FILE
          $ cvs commit -r 1.8 FILE

     The `-f' option disables recursion (i.e., it implies `-l').  To
     force CVS to commit a new revision for all files in all
     subdirectories, you must use `-f -R'.

`-m MESSAGE'
     Use MESSAGE as the log message, instead of invoking an editor.

A.10.2 commit examples
----------------------

A.10.2.1 Committing to a branch
...............................

You can commit to a branch revision (one that has an even number of
dots) with the `-r' option.  To create a branch revision, use the `-b'
option of the `rtag' or `tag' commands (*note Branching and merging::).
Then, either `checkout' or `update' can be used to base your sources
on the newly created branch.  From that point on, all `commit' changes
made within these working sources will be automatically added to a
branch revision, thereby not disturbing main-line development in any
way.  For example, if you had to create a patch to the 1.2 version of
the product, even though the 2.0 version is already under development,
you might do:

     $ cvs rtag -b -r FCS1_2 FCS1_2_Patch product_module
     $ cvs checkout -r FCS1_2_Patch product_module
     $ cd product_module
     [[ hack away ]]
     $ cvs commit

This works automatically since the `-r' option is sticky.

A.10.2.2 Creating the branch after editing
..........................................

Say you have been working on some extremely experimental software,
based on whatever revision you happened to checkout last week.  If
others in your group would like to work on this software with you, but
without disturbing main-line development, you could commit your change
to a new branch.  Others can then checkout your experimental stuff and
utilize the full benefit of CVS conflict resolution.  The scenario might
look like:

     [[ hacked sources are present ]]
     $ cvs tag -b EXPR1
     $ cvs update -r EXPR1
     $ cvs commit

   The `update' command will make the `-r EXPR1' option sticky on all
files.  Note that your changes to the files will never be removed by the
`update' command.  The `commit' will automatically commit to the
correct branch, because the `-r' is sticky.  You could also do like
this:

     [[ hacked sources are present ]]
     $ cvs tag -b EXPR1
     $ cvs commit -r EXPR1

but then, only those files that were changed by you will have the `-r
EXPR1' sticky flag.  If you hack away, and commit without specifying
the `-r EXPR1' flag, some files may accidentally end up on the main
trunk.

   To work with you on the experimental change, others would simply do

     $ cvs checkout -r EXPR1 whatever_module

A.11 diff--Show differences between revisions
=============================================

   * Synopsis: diff [-lR] [-k kflag] [format_options] [(-r rev1[:date1]
     | -D date1) [-r rev2[:date2] | -D date2]] [files...]

   * Requires: working directory, repository.

   * Changes: nothing.

   The `diff' command is used to compare different revisions of files.
The default action is to compare your working files with the revisions
they were based on, and report any differences that are found.

   If any file names are given, only those files are compared.  If any
directories are given, all files under them will be compared.

   The exit status for diff is different than for other CVS commands;
for details *Note Exit status::.

File: cvs.info,  Node: diff options,  Next: diff examples,  Up: diff

A.11.1 diff options
-------------------

These standard options are supported by `diff' (*note Common options::,
for a complete description of them):

`-D DATE'
     Use the most recent revision no later than DATE.  See `-r' for how
     this affects the comparison.

`-k KFLAG'
     Process keywords according to KFLAG.  See *Note Keyword
     substitution::.

`-l'
     Local; run only in current working directory.

`-R'
     Examine directories recursively.  This option is on by default.

`-r TAG[:DATE]'
     Compare with revision specified by TAG or, when DATE is specified
     and TAG is a branch tag, the version from the branch TAG as it
     existed on DATE.  Zero, one or two `-r' options can be present.
     With no `-r' option, the working file will be compared with the
     revision it was based on.  With one `-r', that revision will be
     compared to your current working file.  With two `-r' options
     those two revisions will be compared (and your working file will
     not affect the outcome in any way).

     One or both `-r' options can be replaced by a `-D DATE' option,
     described above.

   The following options specify the format of the output.  They have
the same meaning as in GNU diff.  Most options have two equivalent
names, one of which is a single letter preceded by `-', and the other
of which is a long name preceded by `--'.

`-LINES'
     Show LINES (an integer) lines of context.  This option does not
     specify an output format by itself; it has no effect unless it is
     combined with `-c' or `-u'.  This option is obsolete.  For proper
     operation, `patch' typically needs at least two lines of context.

`-a'
     Treat all files as text and compare them line-by-line, even if they
     do not seem to be text.

`-b'
     Ignore trailing white space and consider all other sequences of
     one or more white space characters to be equivalent.

`-B'
     Ignore changes that just insert or delete blank lines.

`--binary'
     Read and write data in binary mode.

`--brief'
     Report only whether the files differ, not the details of the
     differences.

`-c'
     Use the context output format.

`-C LINES'
`--context[=LINES]'
     Use the context output format, showing LINES (an integer) lines of
     context, or three if LINES is not given.  For proper operation,
     `patch' typically needs at least two lines of context.

`--changed-group-format=FORMAT'
     Use FORMAT to output a line group containing differing lines from
     both files in if-then-else format.  *Note Line group formats::.

`-d'
     Change the algorithm to perhaps find a smaller set of changes.
     This makes `diff' slower (sometimes much slower).

`-e'
`--ed'
     Make output that is a valid `ed' script.

`--expand-tabs'
     Expand tabs to spaces in the output, to preserve the alignment of
     tabs in the input files.

`-f'
     Make output that looks vaguely like an `ed' script but has changes
     in the order they appear in the file.

`-F REGEXP'
     In context and unified format, for each hunk of differences, show
     some of the last preceding line that matches REGEXP.

`--forward-ed'
     Make output that looks vaguely like an `ed' script but has changes
     in the order they appear in the file.

`-H'
     Use heuristics to speed handling of large files that have numerous
     scattered small changes.

`--horizon-lines=LINES'
     Do not discard the last LINES lines of the common prefix and the
     first LINES lines of the common suffix.

`-i'
     Ignore changes in case; consider upper- and lower-case letters
     equivalent.

`-I REGEXP'
     Ignore changes that just insert or delete lines that match REGEXP.

`--ifdef=NAME'
     Make merged if-then-else output using NAME.

`--ignore-all-space'
     Ignore white space when comparing lines.

`--ignore-blank-lines'
     Ignore changes that just insert or delete blank lines.

`--ignore-case'
     Ignore changes in case; consider upper- and lower-case to be the
     same.

`--ignore-matching-lines=REGEXP'
     Ignore changes that just insert or delete lines that match REGEXP.

`--ignore-space-change'
     Ignore trailing white space and consider all other sequences of
     one or more white space characters to be equivalent.

`--initial-tab'
     Output a tab rather than a space before the text of a line in
     normal or context format.  This causes the alignment of tabs in
     the line to look normal.

`-L LABEL'
     Use LABEL instead of the file name in the context format and
     unified format headers.

`--label=LABEL'
     Use LABEL instead of the file name in the context format and
     unified format headers.

`--left-column'
     Print only the left column of two common lines in side by side
     format.

`--line-format=FORMAT'
     Use FORMAT to output all input lines in if-then-else format.
     *Note Line formats::.

`--minimal'
     Change the algorithm to perhaps find a smaller set of changes.
     This makes `diff' slower (sometimes much slower).

`-n'
     Output RCS-format diffs; like `-f' except that each command
     specifies the number of lines affected.

`-N'
`--new-file'
     In directory comparison, if a file is found in only one directory,
     treat it as present but empty in the other directory.

`--new-group-format=FORMAT'
     Use FORMAT to output a group of lines taken from just the second
     file in if-then-else format.  *Note Line group formats::.

`--new-line-format=FORMAT'
     Use FORMAT to output a line taken from just the second file in
     if-then-else format.  *Note Line formats::.

     Use FORMAT to output a group of lines taken from just the first
     file in if-then-else format.  *Note Line group formats::.

`--old-line-format=FORMAT'
     Use FORMAT to output a line taken from just the first file in
     if-then-else format.  *Note Line formats::.

`-p'
     Show which C function each change is in.

`--rcs'
     Output RCS-format diffs; like `-f' except that each command
     specifies the number of lines affected.

`--report-identical-files'
`-s'
     Report when two files are the same.

`--show-c-function'
     Show which C function each change is in.

`--show-function-line=REGEXP'
     In context and unified format, for each hunk of differences, show
     some of the last preceding line that matches REGEXP.

`--side-by-side'
     Use the side by side output format.

`--speed-large-files'
     Use heuristics to speed handling of large files that have numerous
     scattered small changes.

`--suppress-common-lines'
     Do not print common lines in side by side format.

`-t'
     Expand tabs to spaces in the output, to preserve the alignment of
     tabs in the input files.

`-T'
     Output a tab rather than a space before the text of a line in
     normal or context format.  This causes the alignment of tabs in
     the line to look normal.

`--text'
     Treat all files as text and compare them line-by-line, even if they
     do not appear to be text.

`-u'
     Use the unified output format.

`--unchanged-group-format=FORMAT'
     Use FORMAT to output a group of common lines taken from both files

     Use FORMAT to output a line common to both files in if-then-else
     format.  *Note Line formats::.

`-U LINES'
`--unified[=LINES]'
     Use the unified output format, showing LINES (an integer) lines of
     context, or three if LINES is not given.  For proper operation,
     `patch' typically needs at least two lines of context.

`-w'
     Ignore white space when comparing lines.

A.11.1.1 Line group formats
...........................

Line group formats let you specify formats suitable for many
applications that allow if-then-else input, including programming
languages and text formatting languages.  A line group format specifies
the output format for a contiguous group of similar lines.

   For example, the following command compares the TeX file `myfile'
with the original version from the repository, and outputs a merged
file in which old regions are surrounded by `\begin{em}'-`\end{em}'
lines, and new regions are surrounded by `\begin{bf}'-`\end{bf}' lines.

     cvs diff \
        --old-group-format='\begin{em}
     %<\end{em}
     ' \
        --new-group-format='\begin{bf}
     %>\end{bf}
     ' \
        myfile

   The following command is equivalent to the above example, but it is a
little more verbose, because it spells out the default line group
formats.

     cvs diff \
        --old-group-format='\begin{em}
     %<\end{em}
     ' \
        --new-group-format='\begin{bf}
     %>\end{bf}
     ' \
        --unchanged-group-format='%=' \
        --changed-group-format='\begin{em}
     %<\end{em}
     \begin{bf}
     %>\end{bf}
     ' \
        myfile

   Here is a more advanced example, which outputs a diff listing with
headers containing line numbers in a "plain English" style.

     cvs diff \
        --unchanged-group-format='' \
        --old-group-format='-------- %dn line%(n=1?:s) deleted at %df:
     %<' \
        --new-group-format='-------- %dN line%(N=1?:s) added after %de:
     %>' \
        --changed-group-format='-------- %dn line%(n=1?:s) changed at %df:
     %<-------- to:
     %>' \
        myfile

   To specify a line group format, use one of the options listed below.
You can specify up to four line group formats, one for each kind of
line group.  You should quote FORMAT, because it typically contains
shell metacharacters.

`--old-group-format=FORMAT'
     These line groups are hunks containing only lines from the first
     file.  The default old group format is the same as the changed
     group format if it is specified; otherwise it is a format that
     outputs the line group as-is.

`--new-group-format=FORMAT'
     These line groups are hunks containing only lines from the second
     file.  The default new group format is same as the changed group
     format if it is specified; otherwise it is a format that outputs
     the line group as-is.

`--changed-group-format=FORMAT'
     These line groups are hunks containing lines from both files.  The
     default changed group format is the concatenation of the old and
     new group formats.

`--unchanged-group-format=FORMAT'
     These line groups contain lines common to both files.  The default
     unchanged group format is a format that outputs the line group
     as-is.

   In a line group format, ordinary characters represent themselves;
conversion specifications start with `%' and have one of the following
forms.

`%<'
     stands for the lines from the first file, including the trailing
     newline.  Each line is formatted according to the old line format
     (*note Line formats::).

`%>'
     stands for the lines from the second file, including the trailing
     newline.  Each line is formatted according to the new line format.

`%='
     stands for the lines common to both files, including the trailing
     newline.  Each line is formatted according to the unchanged line
     format.

`%%'
     stands for `%'.

`%c'C''
     where C is a single character, stands for C.  C may not be a
     backslash or an apostrophe.  For example, `%c':'' stands for a
     colon, even inside the then-part of an if-then-else format, which
     a colon would normally terminate.

`%c'\O''
     where O is a string of 1, 2, or 3 octal digits, stands for the
     character with octal code O.  For example, `%c'\0'' stands for a
     null character.

`FN'
     where F is a `printf' conversion specification and N is one of the
     following letters, stands for N's value formatted with F.

    `e'
          The line number of the line just before the group in the old
          file.

    `f'
          The line number of the first line in the group in the old
          file; equals E + 1.

    `l'
          The line number of the last line in the group in the old file.

    `m'
          The line number of the line just after the group in the old
          file; equals L + 1.

    `n'
          The number of lines in the group in the old file; equals L -
          F + 1.

    `E, F, L, M, N'
          Likewise, for lines in the new file.


     The `printf' conversion specification can be `%d', `%o', `%x', or
     `%X', specifying decimal, octal, lower case hexadecimal, or upper
     case hexadecimal output respectively.  After the `%' the following
     options can appear in sequence: a `-' specifying
     left-justification; an integer specifying the minimum field width;
     and a period followed by an optional integer specifying the
     minimum number of digits.  For example, `%5dN' prints the number
     of new lines in the group in a field of width 5 characters, using
     the `printf' format `"%5d"'.

`(A=B?T:E)'
     If A equals B then T else E.  A and B are each either a decimal
     constant or a single letter interpreted as above.  This format
     spec is equivalent to T if A's value equals B's; otherwise it is
     equivalent to E.

     For example, `%(N=0?no:%dN) line%(N=1?:s)' is equivalent to `no
     lines' if N (the number of lines in the group in the new file) is
     0, to `1 line' if N is 1, and to `%dN lines' otherwise.


File: cvs.info,  Node: Line formats,  Prev: Line group formats,  Up: diff options

A.11.1.2 Line formats
.....................

Line formats control how each line taken from an input file is output
as part of a line group in if-then-else format.

   For example, the following command outputs text with a one-column
change indicator to the left of the text.  The first column of output
is `-' for deleted lines, `|' for added lines, and a space for
unchanged lines.  The formats contain newline characters where newlines
are desired on output.

     cvs diff \
        --old-line-format='-%l
     ' \
        --new-line-format='|%l
     ' \
        --unchanged-line-format=' %l
     ' \
        myfile

   To specify a line format, use one of the following options.  You
should quote FORMAT, since it often contains shell metacharacters.

`--old-line-format=FORMAT'
     formats lines just from the first file.

`--new-line-format=FORMAT'
     formats lines just from the second file.

`--unchanged-line-format=FORMAT'
     formats lines common to both files.

`--line-format=FORMAT'
     formats all lines; in effect, it sets all three above options
     simultaneously.

   In a line format, ordinary characters represent themselves;
conversion specifications start with `%' and have one of the following
forms.

`%l'
     stands for the contents of the line, not counting its trailing
     newline (if any).  This format ignores whether the line is
     incomplete.

`%L'
     stands for the contents of the line, including its trailing newline
     (if any).  If a line is incomplete, this format preserves its
     incompleteness.

`%%'
     stands for `%'.

`%c'C''
     where C is a single character, stands for C.  C may not be a
     backslash or an apostrophe.  For example, `%c':'' stands for a
     colon.

`%c'\O''
     where O is a string of 1, 2, or 3 octal digits, stands for the
     character with octal code O.  For example, `%c'\0'' stands for a
     null character.

`Fn'
     where F is a `printf' conversion specification, stands for the
     line number formatted with F.  For example, `%.5dn' prints the
     line number using the `printf' format `"%.5d"'.  *Note Line group
     formats::, for more about printf conversion specifications.


   The default line format is `%l' followed by a newline character.

   If the input contains tab characters and it is important that they
line up on output, you should ensure that `%l' or `%L' in a line format
is just after a tab stop (e.g. by preceding `%l' or `%L' with a tab
character), or you should use the `-t' or `--expand-tabs' option.

   Taken together, the line and line group formats let you specify many
different formats.  For example, the following command uses a format
similar to `diff''s normal format.  You can tailor this command to get
fine control over `diff''s output.

     cvs diff \
        --old-line-format='< %l
     ' \
        --new-line-format='> %l
     ' \
        --old-group-format='%df%(f=l?:,%dl)d%dE
     %<' \
        --new-group-format='%dea%dF%(F=L?:,%dL)
     %>' \
        --changed-group-format='%df%(f=l?:,%dl)c%dF%(F=L?:,%dL)
     %<---
     %>' \
        --unchanged-group-format='' \

A.11.2 diff examples
--------------------

The following line produces a Unidiff (`-u' flag) between revision 1.14
and 1.19 of `backend.c'.  Due to the `-kk' flag no keywords are
substituted, so differences that only depend on keyword substitution
are ignored.

     $ cvs diff -kk -u -r 1.14 -r 1.19 backend.c

   Suppose the experimental branch EXPR1 was based on a set of files
tagged RELEASE_1_0.  To see what has happened on that branch, the
following can be used:

     $ cvs diff -r RELEASE_1_0 -r EXPR1

   A command like this can be used to produce a context diff between
two releases:

     $ cvs diff -c -r RELEASE_1_0 -r RELEASE_1_1 > diffs

   If you are maintaining ChangeLogs, a command like the following just
before you commit your changes may help you write the ChangeLog entry.
All local modifications that have not yet been committed will be
printed.

For example, you might use `export' to prepare source for shipment
off-site.  This command requires that you specify a date or tag (with
`-D' or `-r'), so that you can count on reproducing the source you ship
to others (and thus it always prunes empty directories).

   One often would like to use `-kv' with `cvs export'.  This causes
any keywords to be expanded such that an import done at some other site
will not lose the keyword revision information.  But be aware that
doesn't handle an export containing binary files correctly.  Also be
aware that after having used `-kv', one can no longer use the `ident'
command (which is part of the RCS suite--see ident(1)) which looks for
keyword strings.  If you want to be able to use `ident' you must not
use `-kv'.

A.12.1 export options
---------------------

These standard options are supported by `export' (*note Common
options::, for a complete description of them):

`-D DATE'
     Use the most recent revision no later than DATE.

`-f'
     If no matching revision is found, retrieve the most recent
     revision (instead of ignoring the file).

`-l'
     Local; run only in current working directory.

`-n'
     Do not run any checkout program.

`-R'
     Export directories recursively.  This is on by default.

`-r TAG[:DATE]'
     Export the revision specified by TAG or, when DATE is specified
     and TAG is a branch tag, the version from the branch TAG as it
     existed on DATE.  See *Note Common options::.

   In addition, these options (that are common to `checkout' and
`export') are also supported:

`-d DIR'
     Create a directory called DIR for the working files, instead of
     using the module name.  *Note checkout options::, for complete
     details on how CVS handles this flag.

`-k SUBST'
     Set keyword expansion mode (*note Substitution modes::).

`-N'
     Only useful together with `-d DIR'.  *Note checkout options::, for
     complete details on how CVS handles this flag.

A.13 history--Show status of files and users
============================================

   * Synopsis:     history [-report] [-flags] [-options args] [files...]

   * Requires: the file `$CVSROOT/CVSROOT/history'

   * Changes: nothing.

   CVS can keep a history log that tracks each use of most CVS
commands.  You can use `history' to display this information in various
formats.

   To enable logging, the `LogHistory' config option must be set to
some value other than the empty string and the history file specified by
the `HistoryLogPath' option must be writable by all users who may run
the CVS executable (*note config::).

   To enable the `history' command, logging must be enabled as above and
the `HistorySearchPath' config option (*note config::) must be set to
specify some number of the history logs created thereby and these files
must be readable by each user who might run the `history' command.

   Creating a repository via the `cvs init' command will enable logging
of all possible events to a single history log file
(`$CVSROOT/CVSROOT/history') with read and write permissions for all
users (*note Creating a repository::).

   *Note_ `history' uses `-f', `-l', `-n', and `-p' in ways that
conflict with the normal use inside CVS (*note Common options::).*

* Menu:

* history options::             history options


File: cvs.info,  Node: history options,  Up: history

A.13.1 history options
----------------------

Several options (shown above as `-report')  control  what kind of
report is generated:

`-c'
     Report on each time commit was used (i.e., each time the
     repository was modified).

`-e'
     Everything (all record types).  Equivalent to specifying `-x' with
     all record types.  Of course, `-e' will also include record types
     which are added in a future version of CVS; if you are writing a
     script which can only handle certain record types, you'll want to
     specify `-x'.

`-m MODULE'
     Report on a particular module.  (You can meaningfully use `-m'
     more than once on the command line.)

`-o'
     Report on checked-out modules.  This is the default report type.

`-T'
     Report on all tags.

`-x TYPE'
     Extract a particular set of record types TYPE from the CVS
     history.  The types are indicated by single letters, which you may
     specify in combination.

     Certain commands have a single record type:

    `F'
          release

    `O'
          checkout

    `E'
          export

    `T'
          rtag

     One of five record types may result from an update:

    `C'
          A merge was necessary but collisions were detected (requiring
          manual merging).

    `G'
          A merge was necessary and it succeeded.

    `U'
          A working file was copied from the repository.

    `P'
          A working file was patched to match the repository.

    `W'
          The working copy of a file was deleted during update (because
          it was gone from the repository).

     One of three record types results from commit:

    `A'
          A file was added for the first time.

    `M'
          A file was modified.

    `R'
          A file was removed.

   The options shown as `-flags' constrain or expand the report without
requiring option arguments:

`-a'
     Show data for all users (the default is to show data only for the
     user executing `history').

`-l'
     Show last modification only.

`-w'
     Show only the records for modifications done from the same working
     directory where `history' is executing.

   The options shown as `-options ARGS' constrain the report based on
an argument:

`-b STR'
     Show data back to a record containing  the  string STR  in  either
     the module name, the file name, or the repository path.

`-D DATE'
     Show data since DATE.  This is slightly different from the normal
     use of `-D DATE', which selects the newest revision older than
     DATE.

`-f FILE'
     Show data for a particular file (you can specify several `-f'
     options on the same command line).  This is equivalent to
     specifying the file on the command line.

`-n MODULE'
     Show data for a particular module (you can specify several `-n'
     options on the same command line).

`-p REPOSITORY'
     Show data for a particular source repository  (you can specify
     several `-p' options on the same command line).

`-r REV'
     Show records referring to revisions since the revision or tag
     named REV appears in individual RCS files.  Each RCS file is
     searched for the revision or tag.

`-t TAG'
     Show records since tag TAG was last added to the history file.
     This differs from the `-r' flag above in that it reads only the
     history file, not the RCS files, and is much faster.

`-u NAME'
     Show records for user NAME.

`-z TIMEZONE'
     Show times in the selected records using the specified time zone
     instead of UTC.


File: cvs.info,  Node: import,  Next: log,  Prev: history,  Up: CVS commands

A.14 import--Import sources into CVS, using vendor branches
===========================================================

   * Synopsis: import [-options] repository vendortag releasetag...

   * Requires: Repository, source distribution directory.

   * Changes: repository.

   Use `import' to incorporate an entire source distribution from an
outside source (e.g., a source vendor) into your source repository
directory.  You can use this command both for initial creation of a
repository, and for wholesale updates to the module from the outside
source.  *Note Tracking sources::, for a discussion on this subject.

   The REPOSITORY argument gives a directory name (or a path to a
directory) under the CVS root directory for repositories; if the
directory did not exist, import creates it.

   When you use import for updates to source that has been modified in
your source repository (since a prior import), it will notify you of
any files that conflict in the two branches of development; use
`checkout -j' to reconcile the differences, as import instructs you to
do.

   If CVS decides a file should be ignored (*note cvsignore::), it does
not import it and prints `I ' followed by the filename (*note import
output::, for a complete description of the output).

   If the file `$CVSROOT/CVSROOT/cvswrappers' exists, any file whose
names match the specifications in that file will be treated as packages
and the appropriate filtering will be performed on the file/directory
before being imported.  *Note Wrappers::.

   The outside source is saved in a first-level branch, by default
1.1.1.  Updates are leaves of this branch; for example, files from the
first imported collection of source will be revision 1.1.1.1, then
files from the first imported update will be revision 1.1.1.2, and so
on.

   At least three arguments are required.  REPOSITORY is needed to
identify the collection of source.  VENDORTAG is a tag for the entire
branch (e.g., for 1.1.1).  You must also specify at least one
RELEASETAG to uniquely identify the files at the leaves created each
time you execute `import'.  The RELEASETAG should be new, not
previously existing in the repository file, and uniquely identify the
imported release,

   Note that `import' does _not_ change the directory in which you
invoke it.  In particular, it does not set up that directory as a CVS
working directory; if you want to work with the sources import them
first and then check them out into a different directory (*note Getting
the source::).

A.14.1 import options
---------------------

This standard option is supported by `import' (*note Common options::,
for a complete description):

`-m MESSAGE'
     Use MESSAGE as log information, instead of invoking an editor.

   There are the following additional special options.

`-b BRANCH'
     See *Note Multiple vendor branches::.

`-k SUBST'
     Indicate the keyword expansion mode desired.  This setting will
     apply to all files created during the import, but not to any files
     that previously existed in the repository.  See *Note Substitution
     modes::, for a list of valid `-k' settings.

`-I NAME'
     Specify file names that should be ignored during import.  You can
     use this option repeatedly.  To avoid ignoring any files at all
     (even those ignored by default), specify `-I !'.

     NAME can be a file name pattern of the same type that you can
     specify in the `.cvsignore' file.  *Note cvsignore::.

`-W SPEC'
     Specify file names that should be filtered during import.  You can
     use this option repeatedly.

     SPEC can be a file name pattern of the same type that you can
     specify in the `.cvswrappers' file. *Note Wrappers::.

`-X'
     Modify the algorithm used by CVS when importing new files so that
     new files do not immediately appear on the main trunk.

     Specifically, this flag causes CVS to mark new files as if they
     were deleted on the main trunk, by taking the following steps for
     each file in addition to those normally taken on import: creating
     a new revision on the main trunk indicating that the new file is
     `dead', resetting the new file's default branch, and placing the
     file in the Attic (*note Attic::) directory.

     Use of this option can be forced on a repository-wide basis by
     setting the `ImportNewFilesToVendorBranchOnly' option in
     CVSROOT/config (*note config::).

A.14.2 import output
--------------------

`import' keeps you informed of its progress by printing a line for each
file, preceded by one character indicating the status of the file:

`U FILE'
     The file already exists in the repository and has not been locally
     modified; a new revision has been created (if necessary).

`N FILE'
     The file is a new file which has been added to the repository.

`C FILE'
     The file already exists in the repository but has been locally
     modified; you will have to merge the changes.

`I FILE'
     The file is being ignored (*note cvsignore::).

`L FILE'
     The file is a symbolic link; `cvs import' ignores symbolic links.
     People periodically suggest that this behavior should be changed,
     but if there is a consensus on what it should be changed to, it is
     not apparent.  (Various options in the `modules' file can be used
     to recreate symbolic links on checkout, update, etc.; *note
     modules::.)

A.15 log--Print out log information for files
=============================================

   * Synopsis: log [options] [files...]

   * Requires: repository, working directory.

   * Changes: nothing.

   Display log information for files.  `log' used to call the RCS
utility `rlog'.  Although this is no longer true in the current
sources, this history determines the format of the output and the
options, which are not quite in the style of the other CVS commands.

   The output includes the location of the RCS file, the "head"
revision (the latest revision on the trunk), all symbolic names (tags)
and some other things.  For each revision, the revision number, the
date, the author, the number of lines added/deleted, the commitid and
the log message are printed.  All dates are displayed in local time at
the client. This is typically specified in the `$TZ' environment
variable, which can be set to govern how `log' displays dates.

   *Note_ `log' uses `-R' in a way that conflicts with the normal use
inside CVS (*note Common options::).*

File: cvs.info,  Node: log options,  Next: log examples,  Up: log

A.15.1 log options
------------------

By default, `log' prints all information that is available.  All other
options restrict the output.  Note that the revision selection options
(`-d', `-r', `-s', and `-w') have no effect, other than possibly
causing a search for files in Attic directories, when used in
conjunction with the options that restrict the output to only `log'
header fields (`-b', `-h', `-R', and `-t') unless the `-S' option is
also specified.

`-b'
     Print information about the revisions on the default branch,
     normally the highest branch on the trunk.

`-d DATES'
     Print information about revisions with a checkin date/time in the
     range given by the semicolon-separated list of dates.  The date
     formats accepted are those accepted by the `-D' option to many
     other CVS commands (*note Common options::).  Dates can be
     combined into ranges as follows:

    `D1<D2'
    `D2>D1'
          Select the revisions that were deposited between D1 and D2.

    `<D'
    `D>'
          Select all revisions dated D or earlier.

    `D<'
    `>D'
          Select all revisions dated D or later.

    `D'
          Select the single, latest revision dated D or earlier.

     The `>' or `<' characters may be followed by `=' to indicate an
     inclusive range rather than an exclusive one.

     Note that the separator is a semicolon (;).

`-h'
     Print only the name of the RCS file, name of the file in the
     working directory, head, default branch, access list, locks,
     symbolic names, and suffix.

`-l'
     Local; run only in current working directory.  (Default is to run
     recursively).

`-N'
     Do not print the list of tags for this file.  This option can be
     very useful when your site uses a lot of tags, so rather than
     "more"'ing over 3 pages of tag information, the log information is
     presented without tags at all.

`-R'
     Print only the name of the RCS file.

`-rREVISIONS'
     Print information about revisions given in the comma-separated
     list REVISIONS of revisions and ranges.  The following table
     explains the available range formats:

    `REV1:REV2'
          Revisions REV1 to REV2 (which must be on the same branch).

    `REV1::REV2'
          The same, but excluding REV1.

    `:REV'
    `::REV'
          Revisions from the beginning of the branch up to and
          including REV.

    `REV:'
          Revisions starting with REV to the end of the branch
          containing REV.

    `REV::'
          Revisions starting just after REV to the end of the branch
          containing REV.

    `BRANCH'
          An argument that is a branch means all revisions on that
          branch.

    `BRANCH1:BRANCH2'
    `BRANCH1::BRANCH2'
          A range of branches means all revisions on the branches in
          that range.

    `BRANCH.'
          The latest revision in BRANCH.

     A bare `-r' with no revisions means the latest revision on the
     default branch, normally the trunk.  There can be no space between
     the `-r' option and its argument.

`-S'
     Suppress the header if no revisions are selected.

`-s STATES'
     Print information about revisions whose state attributes match one
     of the states given in the comma-separated list STATES.
     Individual states may be any text string, though CVS commonly only
     uses two states, `Exp' and `dead'.  See *Note admin options:: for
     more information.

`-t'
     Print the same as `-h', plus the descriptive text.

`-wLOGINS'
     Print information about revisions checked in by users with login
     names appearing in the comma-separated list LOGINS.  If LOGINS is
     omitted, the user's login is assumed.  There can be no space
     between the `-w' option and its argument.

   `log' prints the intersection of the revisions selected with the
options `-d', `-s', and `-w', intersected with the union of the
revisions selected by `-b' and `-r'.

A.15.2 log examples
-------------------

Since `log' shows dates in local time, you might want to see them in
Coordinated Universal Time (UTC) or some other timezone.  To do this
you can set your `$TZ' environment variable before invoking CVS:

     $ TZ=UTC cvs log foo.c
     $ TZ=EST cvs log bar.c

   (If you are using a `csh'-style shell, like `tcsh', you would need
to prefix the examples above with `env'.)

   * Changes: nothing.

   * Synonym: `dir' & `list' are synonyms for `ls' and `rdir' & `rlist'
     are synonyms for `rls'.

   The `ls' and `rls' commands are used to list files and directories
in the repository.

   By default `ls' lists the files and directories that belong in your
working directory, what would be there after an `update'.

   By default `rls' lists the files and directories on the tip of the
trunk in the topmost directory of the repository.

   Both commands accept an optional list of file and directory names,
relative to the working directory for `ls' and the topmost directory of
the repository for `rls'.  Neither is recursive by default.

   * Requires: repository.

   * Changes: nothing.

   * Synonym: patch

   Builds a Larry Wall format patch(1) file between two releases, that
can be fed directly into the `patch' program to bring an old release
up-to-date with the new release.  (This is one of the few CVS commands
that operates directly from the repository, and doesn't require a prior
checkout.) The diff output is sent to the standard output device.

   You can specify (using the standard `-r' and `-D' options) any
combination of one or two revisions or dates.  If only one revision or
date is specified, the patch file reflects differences between that
revision or date and the current head revisions in the RCS file.

   Note that if the software release affected is contained in more than
one directory, then it may be necessary to specify the `-p' option to
the `patch' command when patching the old sources, so that `patch' is
able to find the files that are located in other directories.

A.17.1 rdiff options
--------------------

These standard options are supported by `rdiff' (*note Common
options::, for a complete description of them):

`-D DATE'
     Use the most recent revision no later than DATE.

`-f'
     If no matching revision is found, retrieve the most recent
     revision (instead of ignoring the file).

`-k KFLAG'
     Process keywords according to KFLAG.  See *Note Keyword
     substitution::.

`-l'
     Local; don't descend subdirectories.

`-R'
     Examine directories recursively.  This option is on by default.

`-r TAG'
     Use the revision specified by TAG, or when DATE is specified and
     TAG is a branch tag, the version from the branch TAG as it existed
     on DATE.  See *Note Common options::.

   In addition to the above, these options are available:

`-c'
     Use the context diff format.  This is the default format.

`-s'
     Create a summary change report instead of a patch.  The summary
     includes information about files that were changed or added
     between the releases.  It is sent to the standard output device.
     This is useful for finding out, for example, which files have
     changed between two dates or revisions.

`-t'
     A diff of the top two revisions is sent to the standard output
     device.  This is most useful for seeing what the last change to a
     file was.

`-u'
     Use the unidiff format for the context diffs.  Remember that old
     versions of the `patch' program can't handle the unidiff format,
     so if you plan to post this patch to the net you should probably
     not use `-u'.

`-V VN'
     Expand keywords according to the rules current in RCS version VN
     (the expansion format changed with RCS version 5).  Note that this
     option is no longer accepted.  CVS will always expand keywords the
     way that RCS version 5 does.

Suppose you receive mail from foo@example.net asking for an update from
release 1.2 to 1.4 of the tc compiler.  You have no such patches on
hand, but with CVS that can easily be fixed with a command such as this:

     $ cvs rdiff -c -r FOO1_2 -r FOO1_4 tc | \
     $$ Mail -s 'The patches you asked for' foo@example.net

   Suppose you have made release 1.3, and forked a branch called
`R_1_3fix' for bug fixes.  `R_1_3_1' corresponds to release 1.3.1,
which was made some time ago.  Now, you want to see how much
development has been done on the branch.  This command can be used:

A.18 release--Indicate that a Module is no longer in use
========================================================

   * release [-d] directories...

   * Requires: Working directory.

   * Changes: Working directory, history log.

   This command is meant to safely cancel the effect of `cvs checkout'.
Since CVS doesn't lock files, it isn't strictly necessary to use this
command.  You can always simply delete your working directory, if you
like; but you risk losing changes you may have forgotten, and you leave
no trace in the CVS history file (*note history file::) that you've
abandoned your checkout.

   Use `cvs release' to avoid these problems.  This command checks that
no uncommitted changes are present; that you are executing it from
immediately above a CVS working directory; and that the repository
recorded for your files is the same as the repository defined in the
module database.

   If all these conditions are true, `cvs release' leaves a record of
its execution (attesting to your intentionally abandoning your
checkout) in the CVS history log.

A.18.1 release options
----------------------

The `release' command supports one command option:

`-d'
     Delete your working copy of the file if the release succeeds.  If
     this flag is not given your files will remain in your working
     directory.

     *WARNING:  The `release' command deletes all directories and files
     recursively.  This has the very serious side-effect that any
     directory that you have created inside your checked-out sources,
     and not added to the repository (using the `add' command; *note
     Adding files::) will be silently deleted--even if it is non-empty!*


File: cvs.info,  Node: release output,  Next: release examples,  Prev: release options,  Up: release

A.18.2 release output
---------------------

Before `release' releases your sources it will print a one-line message
for any file that is not up-to-date.

`U FILE'
`P FILE'
     There exists a newer revision of this file in the repository, and
     you have not modified your local copy of the file (`U' and `P'
     mean the same thing).

`A FILE'
     The file has been added to your private copy of the sources, but
     has not yet been committed to the repository.  If you delete your
     copy of the sources this file will be lost.

`R FILE'
     The file has been removed from your private copy of the sources,
     but has not yet been removed from the repository, since you have
     not yet committed the removal.  *Note commit::.

`M FILE'
     The file is modified in your working directory.  There might also
     be a newer revision inside the repository.

`? FILE'
     FILE is in your working directory, but does not correspond to
     anything in the source repository, and is not in the list of files
     for CVS to ignore (see the description of the `-I' option, and
     *note cvsignore::).  If you remove your working sources, this file
     will be lost.


File: cvs.info,  Node: release examples,  Prev: release output,  Up: release

A.18.3 release examples
-----------------------

Release the `tc' directory, and delete your local working copy of the
files.

     $ cd ..         # You must stand immediately above the
                     # sources when you issue `cvs release'.
     $ cvs release -d tc
     You have [0] altered files in this repository.
     Are you sure you want to release (and delete) directory `tc': y

A.19 server & pserver--Act as a server for a client on stdin/stdout
===================================================================

   * pserver [-c path]

     server [-c path]

   * Requires: repository, client conversation on stdin/stdout

   * Changes: Repository or, indirectly, client working directory.

   The CVS `server' and `pserver' commands are used to provide
repository access to remote clients and expect a client conversation on
stdin & stdout.  Typically these commands are launched from `inetd' or
via `ssh' (*note Remote repositories::).

   `server' expects that the client has already been authenticated
somehow, typically via SSH, and `pserver' attempts to authenticate the
client itself.

   Only one option is available with the `server' and `pserver'
commands:

`-c path'
     Load configuration from PATH rather than the default location
     `$CVSROOT/CVSROOT/config' (*note config::).  PATH must be
     `/etc/cvs.conf' or prefixed by `/etc/cvs/'.  This option is
     supported beginning with CVS release 1.12.13.

A.20 update--Bring work tree in sync with repository
====================================================

   * update [-ACdflPpR] [-I name] [-j rev [-j rev]] [-k kflag] [-r
     tag[:date] | -D date] [-W spec] files...

   * Requires: repository, working directory.

   * Changes: working directory.

   After you've run checkout to create your private copy of source from
the common repository, other developers will continue changing the
central source.  From time to time, when it is convenient in your
development process, you can use the `update' command from within your
working directory to reconcile your work with any revisions applied to
the source repository since your last checkout or update.  Without the
`-C' option, `update' will also merge any differences between the local
copy of files and their base revisions into any destination revisions
specified with `-r', `-D', or `-A'.

* Menu:

* update options::              update options
* update output::               update output


File: cvs.info,  Node: update options,  Next: update output,  Up: update

A.20.1 update options
---------------------

These standard options are available with `update' (*note Common
options::, for a complete description of them):

`-D date'
     Use the most recent revision no later than DATE.  This option is
     sticky, and implies `-P'.  See *Note Sticky tags::, for more
     information on sticky tags/dates.

`-f'
     Only useful with the `-D' or `-r' flags.  If no matching revision
     is found, retrieve the most recent revision (instead of ignoring
     the file).

`-k KFLAG'
     Process keywords according to KFLAG.  See *Note Keyword
     substitution::.  This option is sticky; future updates of this
     file in this working directory will use the same KFLAG.  The
     `status' command can be viewed to see the sticky options.  See
     *Note Invoking CVS::, for more information on the `status' command.

`-l'
     Local; run only in current working directory.  *Note Recursive
     behavior::.

`-P'
     Prune empty directories.  See *Note Moving directories::.

`-p'
     Pipe files to the standard output.

`-R'
     Update directories recursively (default).  *Note Recursive
     behavior::.

`-r TAG[:DATE]'
     Retrieve the revisions specified by TAG or, when DATE is specified
     and TAG is a branch tag, the version from the branch TAG as it
     existed on DATE.  This option is sticky, and implies `-P'.  See
     *Note Sticky tags::, for more information on sticky tags/dates.
     Also see *Note Common options::.

   These special options are also available with `update'.

`-A'
     Reset any sticky tags, dates, or `-k' options.  See *Note Sticky
     tags::, for more information on sticky tags/dates.

`-C'
     Overwrite locally modified files with clean copies from the
     repository (the modified file is saved in `.#FILE.REVISION',
     however).

`-d'
     Create any directories that exist in the repository if they're
     missing from the working directory.  Normally, `update' acts only
     on directories and files that were already enrolled in your
     working directory.

     This is useful for updating directories that were created in the
     repository since the initial checkout; but it has an unfortunate
     side effect.  If you deliberately avoided certain directories in
     the repository when you created your working directory (either
     through use of a module name or by listing explicitly the files
     and directories you wanted on the command line), then updating
     with `-d' will create those directories, which may not be what you
     want.

`-I NAME'
     Ignore files whose names match NAME (in your working directory)
     during the update.  You can specify `-I' more than once on the
     command line to specify several files to ignore.  Use `-I !' to
     avoid ignoring any files at all.  *Note cvsignore::, for other
     ways to make CVS ignore some files.

`-WSPEC'
     Specify file names that should be filtered during update.  You can
     use this option repeatedly.

     SPEC can be a file name pattern of the same type that you can
     specify in the `.cvswrappers' file. *Note Wrappers::.

`-jREVISION'
     With two `-j' options, merge changes from the revision specified
     with the first `-j' option to the revision specified with the
     second `j' option, into the working directory.

     With one `-j' option, merge changes from the ancestor revision to
     the revision specified with the `-j' option, into the working
     directory.  The ancestor revision is the common ancestor of the
     revision which the working directory is based on, and the revision
     specified in the `-j' option.

     Note that using a single `-j TAGNAME' option rather than `-j
     BRANCHNAME' to merge changes from a branch will often not remove
     files which were removed on the branch.  *Note Merging adds and
     removals::, for more.

     In addition, each `-j' option can contain an optional date
     specification which, when used with branches, can limit the chosen
     revision to one within a specific date.  An optional date is
     specified by adding a colon (:) to the tag:
     `-jSYMBOLIC_TAG:DATE_SPECIFIER'.

     *Note Branching and merging::.



File: cvs.info,  Node: update output,  Prev: update options,  Up: update

A.20.2 update output
--------------------

`update' and `checkout' keep you informed of their progress by printing
a line for each file, preceded by one character indicating the status
of the file:

`U FILE'
     The file was brought up to date with respect to the repository.
     This is done for any file that exists in the repository but not in
     your working directory, and for files that you haven't changed but
     are not the most recent versions available in the repository.

`P FILE'
     Like `U', but the CVS server sends a patch instead of an entire
     file.  This accomplishes the same thing as `U' using less
     bandwidth.

`A FILE'
     The file has been added to your private copy of the sources, and
     will be added to the source repository when you run `commit' on
     the file.  This is a reminder to you that the file needs to be
     committed.

`R FILE'
     The file has been removed from your private copy of the sources,
     and will be removed from the source repository when you run
     `commit' on the file.  This is a reminder to you that the file
     needs to be committed.

`M FILE'
     The file is modified in  your  working  directory.

     `M' can indicate one of two states for a file you're working on:
     either there were no modifications to the same file in the
     repository, so that your file remains as you last saw it; or there
     were modifications in the repository as well as in your copy, but
     they were merged successfully, without conflict, in your working
     directory.

     CVS will print some messages if it merges your work, and a backup
     copy of your working file (as it looked before you ran `update')
     will be made.  The exact name of that file is printed while
     `update' runs.

`C FILE'
     A conflict was detected while trying to merge your changes to FILE
     with changes from the source repository.  FILE (the copy in your
     working directory) is now the result of attempting to merge the
     two revisions; an unmodified copy of your file is also in your
     working directory, with the name `.#FILE.REVISION' where REVISION
     is the revision that your modified file started from.  Resolve the
     conflict as described in *Note Conflicts example::.  (Note that
     some systems automatically purge files that begin with `.#' if
     they have not been accessed for a few days.  If you intend to keep
     a copy of your original file, it is a very good idea to rename
     it.)  Under VMS, the file name starts with `__' rather than `.#'.

`? FILE'
     FILE is in your working directory, but does not correspond to
     anything in the source repository, and is not in the list of files
     for CVS to ignore (see the description of the `-I' option, and
     *note cvsignore::).

Appendix C Reference manual for Administrative files
****************************************************

Inside the repository, in the directory `$CVSROOT/CVSROOT', there are a
number of supportive files for CVS.  You can use CVS in a limited
fashion without any of them, but if they are set up properly they can
help make life easier.  For a discussion of how to edit them, see *Note
Intro administrative files::.

   The most important of these files is the `modules' file, which
defines the modules inside the repository.

C.1 The modules file
====================

The `modules' file records your definitions of names for collections of
source code.  CVS will use these definitions if you use CVS to update
the modules file (use normal commands like `add', `commit', etc).

   The `modules' file may contain blank lines and comments (lines
beginning with `#') as well as module definitions.  Long lines can be
continued on the next line by specifying a backslash (`\') as the last
character on the line.

   There are three basic types of modules: alias modules, regular
modules, and ampersand modules.  The difference between them is the way
that they map files in the repository to files in the working
directory.  In all of the following examples, the top-level repository
contains a directory called `first-dir', which contains two files,
`file1' and `file2', and a directory `sdir'.  `first-dir/sdir' contains
a file `sfile'.

* Regular modules::
* Ampersand modules::
* Excluding directories::     Excluding directories from a module
* Module options::            Regular and ampersand modules can take options
* Module program options::    How the modules ``program options'' programs
                              are run.


File: cvs.info,  Node: Alias modules,  Next: Regular modules,  Up: modules

C.1.1 Alias modules
-------------------

Alias modules are the simplest kind of module:

`MNAME -a ALIASES...'
     This represents the simplest way of defining a module MNAME.  The
     `-a' flags the definition as a simple alias: CVS will treat any
     use of MNAME (as a command argument) as if the list of names
     ALIASES had been specified instead.  ALIASES may contain either
     other module names or paths.  When you use paths in aliases,
     `checkout' creates all intermediate directories in the working
     directory, just as if the path had been specified explicitly in
     the CVS arguments.

   For example, if the modules file contains:

     amodule -a first-dir

then the following two commands are equivalent:

     $ cvs co amodule
     $ cvs co first-dir

and they each would provide output such as:

     cvs checkout: Updating first-dir
     U first-dir/file1
     U first-dir/file2
     cvs checkout: Updating first-dir/sdir
     U first-dir/sdir/sfile


File: cvs.info,  Node: Regular modules,  Next: Ampersand modules,  Prev: Alias modules,  Up: modules

C.1.2 Regular modules
---------------------

`MNAME [ options ] DIR [ FILES... ]'
     In the simplest case, this form of module definition reduces to
     `MNAME DIR'.  This defines all the files in directory DIR as
     module mname.  DIR is a relative path (from `$CVSROOT') to a
     directory of source in the source repository.  In this case, on
     checkout, a single directory called MNAME is created as a working
     directory; no intermediate directory levels are used by default,
     even if DIR was a path involving several directory levels.

   For example, if a module is defined by:

     regmodule first-dir

then regmodule will contain the files from first-dir:

     $ cvs co regmodule
     cvs checkout: Updating regmodule
     U regmodule/file1
     U regmodule/file2
     cvs checkout: Updating regmodule/sdir
     U regmodule/sdir/sfile
     $

   By explicitly specifying files in the module definition after DIR,
you can select particular files from directory DIR.  Here is an example:

     regfiles first-dir/sdir sfile

With this definition, getting the regfiles module will create a single
working directory `regfiles' containing the file listed, which comes
from a directory deeper in the CVS source repository:

     $ cvs co regfiles
     U regfiles/sfile
     $


File: cvs.info,  Node: Ampersand modules,  Next: Excluding directories,  Prev: Regular modules,  Up: modules

C.1.3 Ampersand modules
-----------------------

A module definition can refer to other modules by including `&MODULE'
in its definition.
     MNAME [ options ] &MODULE...

   Then getting the module creates a subdirectory for each such module,
in the directory containing the module.  For example, if modules
contains

     ampermod &first-dir

then a checkout will create an `ampermod' directory which contains a
directory called `first-dir', which in turns contains all the
directories and files which live there.  For example, the command

     $ cvs co ampermod

will create the following files:

     ampermod/first-dir/file1
     ampermod/first-dir/file2
     ampermod/first-dir/sdir/sfile

   There is one quirk/bug: the messages that CVS prints omit the
`ampermod', and thus do not correctly display the location to which it
is checking out the files:

     $ cvs co ampermod
     cvs checkout: Updating first-dir
     U first-dir/file1
     U first-dir/file2
     cvs checkout: Updating first-dir/sdir
     U first-dir/sdir/sfile
     $

   Do not rely on this buggy behavior; it may get fixed in a future
release of CVS.

C.1.4 Excluding directories
---------------------------

An alias module may exclude particular directories from other modules
by using an exclamation mark (`!') before the name of each directory to
be excluded.

   For example, if the modules file contains:

     exmodule -a !first-dir/sdir first-dir

then checking out the module `exmodule' will check out everything in
`first-dir' except any files in the subdirectory `first-dir/sdir'.


File: cvs.info,  Node: Module options,  Next: Module program options,  Prev: Excluding directories,  Up: modules

C.1.5 Module options
--------------------

Either regular modules or ampersand modules can contain options, which
supply additional information concerning the module.

`-d NAME'
     Name the working directory something other than the module name.

`-e PROG'
     Specify a program PROG to run whenever files in a module are
     exported.  PROG runs with a single argument, the module name.

`-o PROG'
     Specify a program PROG to run whenever files in a module are
     checked out.  PROG runs with a single argument, the module name.
     See *Note Module program options:: for information on how PROG is
     called.

`-s STATUS'
     Assign a status to the module.  When the module file is printed
     with `cvs checkout -s' the modules are sorted according to
     primarily module status, and secondarily according to the module
     name.  This option has no other meaning.  You can use this option
     for several things besides status: for instance, list the person
     that is responsible for this module.

`-t PROG'
     Specify a program PROG to run whenever files in a module are
     tagged with `rtag'.  PROG runs with two arguments: the module name
     and the symbolic tag specified to `rtag'.  It is not run when
     `tag' is executed.  Generally you will find that the `taginfo'
     file is a better solution (*note taginfo::).

   You should also see *note Module program options:: about how the
"program options" programs are run.


File: cvs.info,  Node: Module program options,  Prev: Module options,  Up: modules

C.1.6 How the modules file "program options" programs are run
-------------------------------------------------------------

For checkout, rtag, and export, the program is server-based, and as
such the following applies:-

   If using remote access methods (pserver, ext, etc.), CVS will
execute this program on the server from a temporary directory. The path
is searched for this program.

   If using "local access" (on a local or remote NFS file system, i.e.
repository set just to a path), the program will be executed from the
newly checked-out tree, if found there, or alternatively searched for
in the path if not.

   The programs are all run after the operation has effectively
completed.


File: cvs.info,  Node: Wrappers,  Next: Trigger Scripts,  Prev: modules,  Up: Administrative files

C.2 The cvswrappers file
========================

Wrappers refers to a CVS feature which lets you control certain
settings based on the name of the file which is being operated on.  The
settings are `-k' for binary files, and `-m' for nonmergeable text
files.

   The `-m' option specifies the merge methodology that should be used
when a non-binary file is updated.  `MERGE' means the usual CVS
behavior: try to merge the files.  `COPY' means that `cvs update' will
refuse to merge files, as it also does for files specified as binary
with `-kb' (but if the file is specified as binary, there is no need to
specify `-m 'COPY'').  CVS will provide the user with the two versions
of the files, and require the user using mechanisms outside CVS, to
insert any necessary changes.

   *WARNING: do not use `COPY' with CVS 1.9 or earlier - such versions
of CVS will copy one version of your file over the other, wiping out
the previous contents.* The `-m' wrapper option only affects behavior
when merging is done on update; it does not affect how files are
stored.  See *Note Binary files::, for more on binary files.

   The basic format of the file `cvswrappers' is:

     wildcard     [option value][option value]...

     where option is one of
     -m           update methodology      value: MERGE or COPY
     -k           keyword expansion       value: expansion mode

     and value is a single-quote delimited value.

   For example, the following command imports a directory, treating
files whose name ends in `.exe' as binary:

     cvs import -I ! -W "*.exe -k 'b'" first-dir vendortag reltag


File: cvs.info,  Node: Trigger Scripts,  Next: rcsinfo,  Prev: Wrappers,  Up: Administrative files

C.3 The Trigger Scripts
=======================

Several of the administrative files support triggers, or the launching
external scripts or programs at specific times before or after
particular events, during the execution of CVS commands.  These hooks
can be used to prevent certain actions, log them, and/or maintain
anything else you deem practical.

   All the trigger scripts are launched in a copy of the user sandbox
being committed, on the server, in client-server mode.  In local mode,
the scripts are actually launched directly from the user sandbox
directory being committed.  For most intents and purposes, the same
scripts can be run in both locations without alteration.

File: cvs.info,  Node: syntax,  Next: Trigger Script Security,  Up: Trigger Scripts

C.3.1 The common syntax
-----------------------

The administrative files such as `commitinfo', `loginfo', `rcsinfo',
`verifymsg', etc., all have a common format.  The purpose of the files
are described later on.  The common syntax is described here.

   Each line contains the following:

   * A regular expression or the literal string `DEFAULT'.  Some script
     hooks also support the literal string `ALL'.  Other than the `ALL'
     and `DEFAULT' keywords, this is a basic regular expression in the
     syntax used by GNU emacs.  See the descriptions of the individual
     script hooks for information on whether the `ALL' keyword is
     supported (*note Trigger Scripts::).

   * A whitespace separator--one or more spaces and/or tabs.

   * A file name or command-line template.

Blank lines are ignored.  Lines that start with the character `#' are
treated as comments.  Long lines unfortunately can _not_ be broken in
two parts in any way.

   The first regular expression that matches the current directory name
in the repository or the first line containing `DEFAULT' in lieu of a
regular expression is used and all lines containing `ALL' is used for
the hooks which support the `ALL' keyword.  The rest of the line is
used as a file name or command-line template as appropriate.  See the
descriptions of the individual script hooks for information on whether
the `ALL' keyword is supported (*note Trigger Scripts::).

_Note:  The following information on format strings is valid as long as
the line `UseNewInfoFmtStrings=yes' appears in your repository's config
file (*note config::).  Otherwise, default format strings may be
appended to the command line and the `loginfo' file, especially, can
exhibit slightly different behavior.  For more information, *Note
Updating Commit Files::._

   In the cases where the second segment of the matched line is a
command line template (e.g. `commitinfo', `loginfo', & `verifymsg'),
the command line template may contain format strings which will be
replaced with specific values before the script is run.

   Format strings can represent a single variable or one or more
attributes of a list variable.  An example of a list variable would be
the list available to scripts hung on the loginfo hooks - the list of
files which were just committed.  In the case of loginfo, three
attributes are available for each list item: file name, precommit
version, and postcommit version.

   Format strings consist of a `%' character followed by an optional
`{' (required in the multiple list attribute case), a single format
character representing a variable or a single attribute of list
elements or multiple format characters representing attributes of list
elements, and a closing `}' when the open bracket was present.

   _Flat format strings_, or single format characters which get replaced
with a single value, will generate a single argument to the called
script, regardless of whether the replacement variable contains white
space or other special characters.

   _List attributes_ will generate an argument for each attribute
requested for each list item.  For example, `%{sVv}' in a `loginfo'
command template will generate three arguments (file name, precommit
version, postcommit version, ...) for each file committed.  As in the
flat format string case, each attribute will be passed in as a single
argument regardless of whether it contains white space or other special
characters.

   `%%' will be replaced with a literal `%'.

   The format strings available to all script hooks are:

c
     The canonical name of the command being executed.  For instance,
     in the case of a hook run from `cvs up', CVS would replace `%c'
     with the string `update' and, in the case of a hook run from `cvs
     ci', CVS would replace `%c' with the string `commit'.

n
     The null, or empty, string.

p
     The name of the directory being operated on within the repository.

r
     The name of the repository (the path portion of `$CVSROOT').

R
     On a server, the name of the referrer, if any.  The referrer is
     the CVSROOT the client reports it used to contact a server which
     then referred it to this server.  Should usually be set on a
     primary server with a write proxy setup.

   Other format strings are file specific.  See the docs on the
particular script hooks for more information (*note Trigger Scripts::).

   As an example, the following line in a `loginfo' file would match
only the directory `module' and any subdirectories of `module':

     ^module\(/\|$\) (echo; echo %p; echo %{sVv}; cat) >>$CVSROOT/CVSROOT/commitlog

   Using this same line and assuming a commit of new revisions 1.5.4.4
and 1.27.4.1 based on old revisions 1.5.4.3 and 1.27, respectively, of
file1 and file2 in module, something like the following log message
should be appended to commitlog:


     module
     file1 1.5.4.3 1.5.4.4 file2 1.27 1.27.4.1
     Update of /cvsroot/module
     In directory localhost.localdomain:/home/jrandom/work/module

     Modified Files:
     	file1 file2
     Log Message:
     A log message.

C.3.2 Security and the Trigger Scripts
--------------------------------------

Security is a huge subject, and implementing a secure system is a
non-trivial task.  This section will barely touch on all the issues
involved, but it is well to note that, as with any script you will be
allowing an untrusted user to run on your server, there are measures
you can take to help prevent your trigger scripts from being abused.

   For instance, since the CVS trigger scripts all run in a copy of the
user's sandbox on the server, a naively coded Perl trigger script which
attempts to use a Perl module that is not installed on the system can
be hijacked by any user with commit access who is checking in a file
with the correct name.  Other scripting languages may be vulnerable to
similar hacks.

   One way to make a script more secure, at least with Perl, is to use
scripts which invoke the `-T', or "taint-check" switch on their `#!'
line.  In the most basic terms, this causes Perl to avoid running code
that may have come from an external source.  Please run the `perldoc
perlsec' command for more on Perl security.  Again, other languages may
implement other security verification hooks which look more or less
like Perl's "taint-check" mechanism.

C.3.3 The commit support files
------------------------------

The `-i' flag in the `modules' file can be used to run a certain
program whenever files are committed (*note modules::).  The files
described in this section provide other, more flexible, ways to run
programs whenever something is committed.

   There are three kinds of programs that can be run on commit.  They
are specified in files in the repository, as described below.  The
following table summarizes the file names and the purpose of the
corresponding programs.

`commitinfo'
     The program is responsible for checking that the commit is
     allowed.  If it exits with a non-zero exit status the commit will
     be aborted.  *Note commitinfo::.

`verifymsg'
     The specified program is used to evaluate the log message, and
     possibly verify that it contains all required fields.  This is
     most useful in combination with the `rcsinfo' file, which can hold
     a log message template (*note rcsinfo::).  *Note verifymsg::.

`loginfo'
     The specified program is called when the commit is complete.  It
     receives the log message and some additional information and can
     store the log message in a file, or mail it to appropriate
     persons, or maybe post it to a local newsgroup, or...  Your
     imagination is the limit!  *Note loginfo::.

* Updating Commit Files::       Updating legacy repositories to stop using
                                deprecated command line template formats


File: cvs.info,  Node: Updating Commit Files,  Up: commit files

C.3.3.1 Updating legacy repositories to stop using deprecated command line template formats
...........................................................................................

New repositories are created set to use the new format strings by
default, so if you are creating a new repository, you shouldn't have to
worry about this section.

   If you are attempting to maintain a legacy repository which was
making use of the `commitinfo', `editinfo', `verifymsg', `loginfo',
and/or `taginfo' script hooks, you should have no immediate problems
with using the current CVS executable, but your users will probably
start to see deprecation warnings.

   The reason for this is that all of the script hooks have been
updated to use a new command line parser that extensibly supports
multiple `loginfo' & `notify' style format strings (*note syntax::) and
this support is not completely compatible with the old style format
strings.

   The quick upgrade method is to stick a `1' after each format string
in your old `loginfo' file.  For example:

     DEFAULT (echo ""; id; echo %{sVv}; date; cat) >> $CVSROOT/CVSROOT/commitlog

   would become:

     DEFAULT (echo ""; id; echo %1{sVv}; date; cat) >> $CVSROOT/CVSROOT/commitlog

   If you were counting on the fact that only the first `%' in the line
was replaced as a format string, you may also have to double up any
further percent signs on the line.

   If you did this all at once and checked it in, everything should
still be running properly.

   Now add the following line to your config file (*note config::):
     UseNewInfoFmtStrings=yes

   Everything should still be running properly, but your users will
probably start seeing new deprecation warnings.

   Dealing with the deprecation warnings now generated by `commitinfo',
`editinfo', `verifymsg', and `taginfo' should be easy.  Simply specify
what are currently implicit arguments explicitly.  This means appending
the following strings to each active command line template in each file:
`commitinfo'
     ` %r/%p %s'

`editinfo'
     ` %l'

`taginfo'
     ` %t %o %p %{sv}'

`verifymsg'
     ` %l'

   If you don't desire that any of the newly available information be
passed to the scripts hanging off of these hooks, no further
modifications to these files should be necessary to insure current and
future compatibility with CVS's format strings.

   Fixing `loginfo' could be a little tougher.  The old style `loginfo'
format strings caused a single space and comma separated argument to be
passed in in place of the format string.  This is what will continue to
be generated due to the deprecated `1' you inserted into the format
strings.

   Since the new format separates each individual item and passes it
into the script as a separate argument (for a good reason - arguments
containing commas and/or white space are now parsable), to remove the
deprecated `1' from your `loginfo' command line templates, you will
most likely have to rewrite any scripts called by the hook to handle
the new argument format.

   Also note that the way `%' followed by unrecognized characters and by
`{}' was treated in past versions of CVS is not strictly adhered to as
there were bugs in the old versions.  Specifically, `%{}' would eat the
next character and unrecognized strings resolved only to the empty
string, which was counter to what was stated in the documentation.
This version will do what the documentation said it should have (if you
were using only some combination of `%{sVv}', e.g. `%{sVv}', `%{sV}', or
`%v', you should have no troubles).

   On the bright side, you should have plenty of time to do this before
all support for the old format strings is removed from CVS, so you can
just put up with the deprecation warnings for awhile if you like.


File: cvs.info,  Node: commitinfo,  Next: verifymsg,  Prev: commit files,  Up: Trigger Scripts

C.3.4 Commitinfo
----------------

The `commitinfo' file defines programs to execute whenever `cvs commit'
is about to execute.  These programs are used for pre-commit checking
to verify that the modified, added and removed files are really ready
to be committed.  This could be used, for instance, to verify that the
changed files conform to to your site's standards for coding practice.

   The `commitinfo' file has the standard form for script hooks (*note
Trigger Scripts::), where each line is a regular expression followed by
a command to execute.  It supports only the DEFAULT keywords.

   In addition to the common format strings (*note syntax::),
`commitinfo' supports:

{s}
     a list of the names of files to be committed

   Currently, if no format strings are specified, a default string of `
%r/%p %{s}' will be appended to the command line template before
replacement is performed, but this feature is deprecated.  It is simply
in place so that legacy repositories will remain compatible with the
new CVS application.  For information on updating, *note Updating
Commit Files::.

   The first line with a regular expression matching the directory
within the repository will be used.  If the command returns a non-zero
exit status the commit will be aborted.

   The command will be run in the root of the workspace containing the
new versions of any files the user would like to modify (commit), _or
in a copy of the workspace on the server (*note Remote
repositories::)_.  If a file is being removed, there will be no copy of
the file under the current directory.  If a file is being added, there
will be no corresponding archive file in the repository unless the file
is being resurrected.

   Note that both the repository directory and the corresponding Attic
(*note Attic::) directory may need to be checked to locate the archive
file corresponding to any given file being committed.  Much of the
information about the specific commit request being made, including the
destination branch, commit message, and command line options specified,
is not available to the command.


File: cvs.info,  Node: verifymsg,  Next: loginfo,  Prev: commitinfo,  Up: Trigger Scripts

C.3.5 Verifying log messages
----------------------------

Once you have entered a log message, you can evaluate that message to
check for specific content, such as a bug ID.  Use the `verifymsg' file
to specify a program that is used to verify the log message.  This
program could be a simple script that checks that the entered message
contains the required fields.

   The `verifymsg' file is often most useful together with the
`rcsinfo' file, which can be used to specify a log message template
(*note rcsinfo::).

   The `verifymsg' file has the standard form for script hooks (*note
Trigger Scripts::), where each line is a regular expression followed by
a command to execute.  It supports only the DEFAULT keywords.

   In addition to the common format strings (*note syntax::),
`verifymsg' supports:

l
     the full path to the file containing the log message to be verified

{sV}
     File attributes, where:
    s
          file name

    V
          old version number (pre-checkin)

   Currently, if no format strings are specified, a default string of `
%l' will be appended to the command line template before replacement is
performed, but this feature is deprecated.  It is simply in place so
that legacy repositories will remain compatible with the new CVS
application.  For information on updating, *note Updating Commit
Files::.

   One thing that should be noted is that the `ALL' keyword is not
supported.  If more than one matching line is found, the first one is
used.  This can be useful for specifying a default verification script
in a directory, and then overriding it in a subdirectory.

   If the verification script exits with a non-zero exit status, the
commit is aborted.

   In the default configuration, CVS allows the verification script to
change the log message. This is controlled via the RereadLogAfterVerify
CVSROOT/config option.

   When `RereadLogAfterVerify=always' or `RereadLogAfterVerify=stat',
the log message will either always be reread after the verification
script is run or reread only if the log message file status has changed.

   *Note config::, for more on CVSROOT/config options.

   It is NOT a good idea for a `verifymsg' script to interact directly
with the user in the various client/server methods. For the `pserver'
method, there is no protocol support for communicating between
`verifymsg' and the client on the remote end. For the `ext' and
`server' methods, it is possible for CVS to become confused by the
characters going along the same channel as the CVS protocol messages.
See *Note Remote repositories::, for more information on client/server
setups.  In addition, at the time the `verifymsg' script runs, the CVS
server has locks in place in the repository.  If control is returned to
the user here then other users may be stuck waiting for access to the
repository.

   This option can be useful if you find yourself using an rcstemplate
that needs to be modified to remove empty elements or to fill in
default values.  It can also be useful if the rcstemplate has changed
in the repository and the CVS/Template was not updated, but is able to
be adapted to the new format by the verification script that is run by
`verifymsg'.

   An example of an update might be to change all occurrences of
'BugId:' to be 'DefectId:' (which can be useful if the rcstemplate has
recently been changed and there are still checked-out user trees with
cached copies in the CVS/Template file of the older version).

   Another example of an update might be to delete a line that contains
'BugID: none' from the log message after validation of that value as
being allowed is made.

File: cvs.info,  Node: verifymsg example,  Up: verifymsg

C.3.5.1 Verifying log messages
..............................

The following is a little silly example of a `verifymsg' file, together
with the corresponding `rcsinfo' file, the log message template and a
verification script.  We begin with the log message template.  We want
to always record a bug-id number on the first line of the log message.
The rest of log message is free text.  The following template is found
in the file `/usr/cvssupport/tc.template'.

     BugId:

   The script `/usr/cvssupport/bugid.verify' is used to evaluate the
log message.

     #!/bin/sh
     #
     #       bugid.verify filename
     #
     #  Verify that the log message contains a valid bugid
     #  on the first line.
     #
     if sed 1q < $1 | grep '^BugId:[ ]*[0-9][0-9]*$' > /dev/null; then
         exit 0
     elif sed 1q < $1 | grep '^BugId:[ ]*none$' > /dev/null; then
         # It is okay to allow commits with 'BugId: none',
         # but do not put that text into the real log message.
         grep -v '^BugId:[ ]*none$' > $1.rewrite
         mv $1.rewrite $1
         exit 0
     else
         echo "No BugId found."
         exit 1
     fi

   The `verifymsg' file contains this line:

     ^tc     /usr/cvssupport/bugid.verify %l

   The `rcsinfo' file contains this line:

     ^tc     /usr/cvssupport/tc.template

   The `config' file contains this line:

     RereadLogAfterVerify=always


File: cvs.info,  Node: loginfo,  Next: postadmin,  Prev: verifymsg,  Up: Trigger Scripts

C.3.6 Loginfo
-------------

The `loginfo' file is used to control where log information is sent
after versioned changes are made to repository archive files and after
directories are added ot the repository.  *Note posttag:: for how to
log tagging information and *Note postadmin:: for how to log changes
due to the `admin' command.

   The `loginfo' file has the standard form for script hooks (*note
Trigger Scripts::), where each line is a regular expression followed by
a command to execute.  It supports the ALL and DEFAULT keywords.

   Any specified scripts are called:

`commit'
     Once per directory, immediately after a successfully completing
     the commit of all files within that directory.

`import'
     Once per import, immediately after completion of all write
     operations.

`add'
     Immediately after the successful `add' of a directory.

   Any script called via `loginfo' will be fed the log information on
its standard input.  Note that the filter program *must* read *all* of
the log information from its standard input or CVS may fail with a
broken pipe signal.

   In addition to the common format strings (*note syntax::), `loginfo'
supports:

{stVv}
     File attributes, where:
    s
          file name

    T
          tag name of destination, or the empty string when there is no
          associated tag name (this usually means the trunk)

    V
          old version number (pre-checkin)

    v
          new version number (post-checkin)

   For example, some valid format strings are `%%', `%s', `%{s}', and
`%{stVv}'.

   Currently, if `UseNewInfoFmtStrings' is not set in the `config'
administration file (*note config::), the format strings will be
substituted as they were in past versions of CVS, but this feature is
deprecated.  It is simply in place so that legacy repositories will
remain compatible with the new CVS application.  For information on
updating, please see *Note Updating Commit Files::.

   As an example, if `/u/src/master/yoyodyne/tc' is the repository, `%p'
and `%{sVv}' are the format strings, and three files (ChangeLog,
Makefile, foo.c) were modified, the output might be:

     yoyodyne/tc ChangeLog 1.1 1.2 Makefile 1.3 1.4 foo.c 1.12 1.13

   Note: when CVS is accessing a remote repository, `loginfo' will be
run on the _remote_ (i.e., server) side, not the client side (*note

C.3.6.1 Loginfo example
.......................

The following `loginfo' file, together with the tiny shell-script
below, appends all log messages to the file
`$CVSROOT/CVSROOT/commitlog', and any commits to the administrative
files (inside the `CVSROOT' directory) are also logged in
`/usr/adm/cvsroot-log'.  Commits to the `prog1' directory are mailed to
ceder.

     ALL                     /usr/local/bin/cvs-log $CVSROOT/CVSROOT/commitlog $USER
     ^CVSROOT\(/\|$\)        /usr/local/bin/cvs-log /usr/adm/cvsroot-log $USER
     ^prog1\(/\|$\)          Mail -s "%p %s" ceder

   The shell-script `/usr/local/bin/cvs-log' looks like this:

     #!/bin/sh
     (echo "------------------------------------------------------";
      echo -n "$2  ";
      date;
      echo;
      cat) >> $1

C.3.6.2 Keeping a checked out copy
..................................

It is often useful to maintain a directory tree which contains files
which correspond to the latest version in the repository.  For example,
other developers might want to refer to the latest sources without
having to check them out, or you might be maintaining a web site with
CVS and want every checkin to cause the files used by the web server to
be updated.

   The way to do this is by having loginfo invoke `cvs update'.  Doing
so in the naive way will cause a problem with locks, so the `cvs update'
must be run in the background.  Here is an example for unix (this
should all be on one line):

     ^cyclic-pages\(/\|$\)	(date; cat; (sleep 2; cd /u/www/local-docs;
      cvs -q update -d) &) >> $CVSROOT/CVSROOT/updatelog 2>&1

   This will cause checkins to repository directory `cyclic-pages' and
its subdirectories to update the checked out tree in
`/u/www/local-docs'.

C.3.7 Logging admin commands
----------------------------

The `postadmin' file defines programs to execute after an `admin'
command modifies files.  The `postadmin' file has the standard form for
script hooks (*note Trigger Scripts::), where each line is a regular
expression followed by a command to execute.  It supports the ALL and
DEFAULT keywords.

   The `postadmin' file supports no format strings other than the common
ones (*note syntax::),


File: cvs.info,  Node: taginfo,  Next: posttag,  Prev: postadmin,  Up: Trigger Scripts

C.3.8 Taginfo
-------------

The `taginfo' file defines programs to execute when someone executes a
`tag' or `rtag' command.  The `taginfo' file has the standard form for
script hooks (*note Trigger Scripts::), where each line is a regular
expression followed by a command to execute.  It supports the ALL and
DEFAULT keywords.

   In addition to the common format strings (*note syntax::), `taginfo'
supports:

b
     tag type (`T' for branch, `N' for not-branch, or `?' for unknown,
     as during delete operations)

o
     operation (`add' for `tag', `mov' for `tag -F', or `del' for `tag
     -d')

t
     new tag name

{sTVv}
     file attributes, where:
    s
          file name

    T
          tag name of destination, or the empty string when there is no
          associated tag name (this usually means the trunk)

    V
          old version number (for a move or delete operation)

    v
          new version number (for an add or move operation)

   For example, some valid format strings are `%%', `%p', `%t', `%s',
`%{s}', and `%{sVv}'.

   Currently, if no format strings are specified, a default string of `
%t %o %p %{sv}' will be appended to the command line template before
replacement is performed, but this feature is deprecated.  It is simply
in place so that legacy repositories will remain compatible with the
new CVS application.  For information on updating, *note Updating
Commit Files::.

   A non-zero exit of the filter program will cause the tag to be
aborted.

   Here is an example of using `taginfo' to log `tag' and `rtag'
commands.  In the `taginfo' file put:

     ALL /usr/local/cvsroot/CVSROOT/loggit %t %b %o %p %{sVv}

Where `/usr/local/cvsroot/CVSROOT/loggit' contains the following script:

     #!/bin/sh
     echo "$@" >>/home/kingdon/cvsroot/CVSROOT/taglog

C.3.9 Logging tags
------------------

The `posttag' file defines programs to execute after a `tag' or `rtag'
command modifies files.  The `posttag' file has the standard form for
script hooks (*note Trigger Scripts::), where each line is a regular
expression followed by a command to execute.  It supports the ALL and
DEFAULT keywords.

   The `posttag' admin file supports the same format strings as the
`taginfo' file (*note taginfo::),


File: cvs.info,  Node: postwatch,  Next: preproxy,  Prev: posttag,  Up: Trigger Scripts

C.3.10 Logging watch commands
-----------------------------

The `postwatch' file defines programs to execute after any command (for
instance, `watch', `edit', `unedit', or `commit') modifies any
`CVS/fileattr' file in the repository (*note Watches::).  The
`postwatch' file has the standard form for script hooks (*note Trigger
Scripts::), where each line is a regular expression followed by a
command to execute.  It supports the ALL and DEFAULT keywords.

   The `postwatch' file supports no format strings other than the common
ones (*note syntax::), but it is worth noting that the `%c' format
string may not be replaced as you might expect.  Client runs of `edit'
and `unedit' can sometimes skip contacting the CVS server and cache the
notification of the file attribute change to be sent the next time the
client contacts the server for whatever other reason,


File: cvs.info,  Node: preproxy,  Next: postproxy,  Prev: postwatch,  Up: Trigger Scripts

C.3.11 Launch a Script before Proxying
--------------------------------------

The `preproxy' file defines programs to execute after a secondary
server receives a write request from a client, just before it starts up
the primary server and becomes a write proxy.  This hook could be used
to dial a modem, launch an SSH tunnel, establish a VPN, or anything
else that might be necessary to do before contacting the primary server.

   `preproxy' scripts are called once, at the time of the write
request, with the repository argument (if requested) set from the
topmost directory sent by the client.

   The `preproxy' file has the standard form for script hooks (*note
Trigger Scripts::), where each line is a regular expression followed by
a command to execute.  It supports the ALL and DEFAULT keywords.

   In addition to the common format strings, the `preproxy' file
supports the following format string:

P
     the CVSROOT string which specifies the primary server


File: cvs.info,  Node: postproxy,  Prev: preproxy,  Up: Trigger Scripts

C.3.12 Launch a Script after Proxying
-------------------------------------

The `postproxy' file defines programs to execute after a secondary
server notes that the connection to the primary server has shut down
and before it releases the client by shutting down the connection to
the client.  This could hook could be used to disconnect a modem, an
SSH tunnel, a VPN, or anything else that might be necessary to do after
contacting the primary server.  This hook should also be used to pull
updates from the primary server before allowing the client which did
the write to disconnect since otherwise the client's next read request
may generate error messages and fail upon encountering an out of date
repository on the secondary server.

   `postproxy' scripts are called once per directory.

   The `postproxy' file has the standard form for script hooks (*note
Trigger Scripts::), where each line is a regular expression followed by
a command to execute.  It supports the ALL and DEFAULT keywords.

   In addition to the common format strings, the `postproxy' file
supports the following format string:

P
     the CVSROOT string which specifies the primary server


File: cvs.info,  Node: rcsinfo,  Next: cvsignore,  Prev: Trigger Scripts,  Up: Administrative files

C.4 Rcsinfo
===========

The `rcsinfo' file can be used to specify a form to edit when filling
out the commit log.  The `rcsinfo' file has a syntax similar to the
`verifymsg', `commitinfo' and `loginfo' files.  *Note syntax::.  Unlike
the other files the second part is _not_ a command-line template.
Instead, the part after the regular expression should be a full
pathname to a file containing the log message template.

   If the repository name does not match any of the regular expressions
in this file, the `DEFAULT' line is used, if it is specified.

   All occurrences of the name `ALL' appearing as a regular expression
are used in addition to the first matching regular expression or
`DEFAULT'.

   The log message template will be used as a default log message.  If
you specify a log message with `cvs commit -m MESSAGE' or `cvs commit -f
FILE' that log message will override the template.

   *Note verifymsg::, for an example `rcsinfo' file.

   When CVS is accessing a remote repository, the contents of `rcsinfo'
at the time a directory is first checked out will specify a template.
This template will be updated on all `cvs update' commands. It will
also be added to new directories added with a `cvs add new-directory'
command.  In versions of CVS prior to version 1.12, the `CVS/Template'
file was not updated. If the CVS server is at version 1.12 or higher an
older client may be used and the `CVS/Template' will be updated from
the server.

C.5 Ignoring files via cvsignore
================================

There are certain file names that frequently occur inside your working
copy, but that you don't want to put under CVS control.  Examples are
all the object files that you get while you compile your sources.
Normally, when you run `cvs update', it prints a line for each file it
encounters that it doesn't know about (*note update output::).

   CVS has a list of files (or sh(1) file name patterns) that it should
ignore while running `update', `import' and `release'.  This list is
constructed in the following way.

   * The list is initialized to include certain file name patterns:
     names associated with CVS administration, or with other common
     source control systems; common names for patch files, object files,
     archive files, and editor backup files; and other names that are
     usually artifacts of assorted utilities.  Currently, the default
     list of ignored file name patterns is:

              RCS     SCCS    CVS     CVS.adm
              RCSLOG  cvslog.*
              tags    TAGS
              .make.state     .nse_depinfo
              *~      #*      .#*     ,*      _$*     *$
              *.old   *.bak   *.BAK   *.orig  *.rej   .del-*
              *.a     *.olb   *.o     *.obj   *.so    *.exe
              *.Z     *.elc   *.ln
              core

   * The per-repository list in `$CVSROOT/CVSROOT/cvsignore' is
     appended to the list, if that file exists.

   * The per-user list in `.cvsignore' in your home directory is
     appended to the list, if it exists.

   * Any entries in the environment variable `$CVSIGNORE' is appended
     to the list.

   * Any `-I' options given to CVS is appended.

   * As CVS traverses through your directories, the contents of any
     `.cvsignore' will be appended to the list.  The patterns found in
     `.cvsignore' are only valid for the directory that contains them,
     not for any sub-directories.

   In any of the 5 places listed above, a single exclamation mark (`!')
clears the ignore list.  This can be used if you want to store any file
which normally is ignored by CVS.

   Specifying `-I !' to `cvs import' will import everything, which is
generally what you want to do if you are importing files from a
pristine distribution or any other source which is known to not contain
any extraneous files.  However, looking at the rules above you will see
there is a fly in the ointment; if the distribution contains any
`.cvsignore' files, then the patterns from those files will be
processed even if `-I !' is specified.  The only workaround is to
remove the `.cvsignore' files in order to do the import.  Because this
is awkward, in the future `-I !' might be modified to override
`.cvsignore' files in each directory.

   Note that the syntax of the ignore files consists of a series of
lines, each of which contains a space separated list of filenames.
This offers no clean way to specify filenames which contain spaces, but
you can use a workaround like `foo?bar' to match a file named `foo bar'
(it also matches `fooxbar' and the like).  Also note that there is
currently no way to specify comments.


File: cvs.info,  Node: checkoutlist,  Next: history file,  Prev: cvsignore,  Up: Administrative files

C.6 The checkoutlist file
=========================

It may be helpful to use CVS to maintain your own files in the
`CVSROOT' directory.  For example, suppose that you have a script
`logcommit.pl' which you run by including the following line in the
`commitinfo' administrative file:

     ALL   $CVSROOT/CVSROOT/logcommit.pl %r/%p %s

   To maintain `logcommit.pl' with CVS you would add the following line
to the `checkoutlist' administrative file:

     logcommit.pl

   The format of `checkoutlist' is one line for each file that you want
to maintain using CVS, giving the name of the file, followed optionally
by more whitespace and any error message that should print if the file
cannot be checked out into CVSROOT after a commit:

     logcommit.pl	Could not update CVSROOT/logcommit.pl.

   After setting up `checkoutlist' in this fashion, the files listed
there will function just like CVS's built-in administrative files.  For
example, when checking in one of the files you should get a message
such as:

     cvs commit: Rebuilding administrative file database

and the checked out copy in the `CVSROOT' directory should be updated.

   Note that listing `passwd' (*note Password authentication server::)
in `checkoutlist' is not recommended for security reasons.

   For information about keeping a checkout out copy in a more general
context than the one provided by `checkoutlist', see *Note Keeping a
checked out copy::.


File: cvs.info,  Node: history file,  Next: Variables,  Prev: checkoutlist,  Up: Administrative files

C.7 The history file
====================

By default, the file `$CVSROOT/CVSROOT/history' is used to log
information for the `history' command (*note history::).  This file
name may be changed with the `HistoryLogPath' and `HistorySearchPath'
config options (*note config::).

   The file format of the `history' file is documented only in comments
in the CVS source code, but generally programs should use the `cvs
history' command to access it anyway, in case the format changes with
future releases of CVS.


File: cvs.info,  Node: Variables,  Next: config,  Prev: history file,  Up: Administrative files

C.8 Expansions in administrative files
======================================

Sometimes in writing an administrative file, you might want the file to
be able to know various things based on environment CVS is running in.
There are several mechanisms to do that.

   To find the home directory of the user running CVS (from the `HOME'
environment variable), use `~' followed by `/' or the end of the line.
Likewise for the home directory of USER, use `~USER'.  These variables
are expanded on the server machine, and don't get any reasonable
expansion if pserver (*note Password authenticated::) is in use;
therefore user variables (see below) may be a better choice to
customize behavior based on the user running CVS.

   One may want to know about various pieces of information internal to
CVS.  A CVS internal variable has the syntax `${VARIABLE}', where
VARIABLE starts with a letter and consists of alphanumeric characters
and `_'.  If the character following VARIABLE is a non-alphanumeric
character other than `_', the `{' and `}' can be omitted.  The CVS
internal variables are:

`CVSROOT'
     This is the absolute path to the current CVS root directory.
     *Note Repository::, for a description of the various ways to
     specify this, but note that the internal variable contains just
     the directory and not any of the access method information.

`RCSBIN'
     In CVS 1.9.18 and older, this specified the directory where CVS
     was looking for RCS programs.  Because CVS no longer runs RCS
     programs, specifying this internal variable is now an error.

`CVSEDITOR'
`EDITOR'
`VISUAL'
     These all expand to the same value, which is the editor that CVS
     is using.  *Note Global options::, for how to specify this.

`USER'
     Username of the user running CVS (on the CVS server machine).
     When using pserver, this is the user specified in the repository
     specification which need not be the same as the username the
     server is running as (*note Password authentication server::).  Do
     not confuse this with the environment variable of the same name.

`SESSIONID'
     Unique Session ID of the CVS process. This is a random string of
     printable characters of at least 16 characters length. Users
     should assume that it may someday grow to at most 256 characters
     in length.

`COMMITID'
     Unique Session ID of the CVS process. This is a random string of
     printable characters of at least 16 characters length. Users
     should assume that it may someday grow to at most 256 characters
     in length.

   If you want to pass a value to the administrative files which the
user who is running CVS can specify, use a user variable.  To expand a
user variable, the administrative file contains `${=VARIABLE}'.  To set
a user variable, specify the global option `-s' to CVS, with argument
`VARIABLE=VALUE'.  It may be particularly useful to specify this option
via `.cvsrc' (*note ~/.cvsrc::).

   For example, if you want the administrative file to refer to a test
directory you might create a user variable `TESTDIR'.  Then if CVS is
invoked as

     cvs -s TESTDIR=/work/local/tests

and the administrative file contains `sh ${=TESTDIR}/runtests', then
that string is expanded to `sh /work/local/tests/runtests'.

   All other strings containing `$' are reserved; there is no way to
quote a `$' character so that `$' represents itself.

   Environment variables passed to administrative files are:

`CVS_USER'
     The CVS-specific username provided by the user, if it can be
     provided (currently just for the pserver access method), and to
     the empty string otherwise.  (`CVS_USER' and `USER' may differ
     when `$CVSROOT/CVSROOT/passwd' is used to map CVS usernames to
     system usernames.)

`LOGNAME'
     The username of the system user.

`USER'
     Same as `LOGNAME'.  Do not confuse this with the internal variable
     of the same name.


File: cvs.info,  Node: config,  Prev: Variables,  Up: Administrative files

C.9 The CVSROOT/config configuration file
=========================================

Usually, the `config' file is found at `$CVSROOT/CVSROOT/config', but
this may be overridden on the `pserver' and `server' command lines
(*note server & pserver::).

   The administrative file `config' contains various miscellaneous
settings which affect the behavior of CVS.  The syntax is slightly
different from the other administrative files.

   Leading white space on any line is ignored, though the syntax is
very strict and will reject spaces and tabs almost anywhere else.

   Empty lines, lines containing nothing but white space, and lines
which start with `#' (discounting any leading white space) are ignored.

   Other lines consist of the optional leading white space, a keyword,
`=', and a value.  Please note again that this syntax is very strict.
Extraneous spaces or tabs, other than the leading white space, are not
permitted on these lines.

   As of CVS 1.12.13, lines of the form `[CVSROOT]' mark the subsequent
section of the config file as applying only to certain repositories.
Multiple `[CVSROOT]' lines without intervening `KEYWORD=VALUE' pairs
cause processing to fall through, processing subsequent keywords for
any root in the list.  Finally, keywords and values which appear before
any `[CVSROOT]' lines are defaults, and may to apply to any repository.
For example, consider the following file:

     # Defaults
     LogHistory=TMAR

     [/cvsroots/team1]
       LockDir=/locks/team1

     [/cvsroots/team2]
       LockDir=/locks/team2

     [/cvsroots/team3]
       LockDir=/locks/team3

     [/cvsroots/team4]
       LockDir=/locks/team4

     [/cvsroots/team3]
     [/cvsroots/team4]
       # Override logged commands for teams 3 & 4.
       LogHistory=all

   This example file sets up separate lock directories for each
project, as well as a default set of logged commands overridden for the
example's team 3 & team 4. This syntax could be useful, for instance,
if you wished to share a single config file, for instance
`/etc/cvs.conf', among several repositories.

   Currently defined keywords are:

`HistorySearchPath=PATTERN'
     Request that CVS look for its history information in files matching
     PATTERN, which is a standard UNIX file glob.  If PATTERN matches
     multiple files, all will be searched in lexicographically sorted
     order.  *Note history::, and *Note history file::, for more.

     If no value is supplied for this option, it defaults to
     `$CVSROOT/CVSROOT/history'.

`HistoryLogPath=PATH'
     Control where CVS logs its history.  If the file does not exist,
     CVS will attempt to create it.  Format strings, as available to
     the GNU C `strftime' function and often the UNIX date command, and
     the string $CVSROOT will be substituted in this path.  For
     example, consider the line:

          HistoryLogPath=$CVSROOT/CVSROOT/history/%Y-%m-%d

     This line would cause CVS to attempt to create its history file in
     a subdirectory (`history') of the configuration directory
     (`CVSROOT') with a name equal to the current date representation
     in the ISO8601 format (for example, on May 11, 2005, CVS would
     attempt to log its history under the repository root directory in
     a file named `CVSROOT/history/2005-05-11').  *Note history::, and
     *Note history file::, for more.

     If no value is supplied for this option, it defaults to
     `$CVSROOT/CVSROOT/history'.

`ImportNewFilesToVendorBranchOnly=VALUE'
     Specify whether `cvs import' should always behave as if the `-X'
     flag was specified on the command line.  VALUE may be either `yes'
     or `no'.  If set to `yes', all uses of `cvs import' on the
     repository will behave as if the `-X' flag was set.  The default
     value is `no'.

`KeywordExpand=VALUE'
     Specify `i' followed by a list of keywords to be expanded (for
     example, `KeywordExpand=iMYCVS,Name,Date'), or `e' followed by a
     list of keywords not to be expanded (for example,
     `KeywordExpand=eCVSHeader').  For more on keyword expansion, see
     *Note Configuring keyword expansion::.

`LocalKeyword=VALUE'
     Specify a local alias for a standard keyword.  For example,
     `LocalKeyword=MYCVS=CVSHeader'.  For more on local keywords, see
     *Note Keyword substitution::.

`LockDir=DIRECTORY'
     Put CVS lock files in DIRECTORY rather than directly in the
     repository.  This is useful if you want to let users read from the
     repository while giving them write access only to DIRECTORY, not
     to the repository.  It can also be used to put the locks on a very
     fast in-memory file system to speed up locking and unlocking the
     repository.  You need to create DIRECTORY, but CVS will create
     subdirectories of DIRECTORY as it needs them.  For information on
     CVS locks, see *Note Concurrency::.

     Before enabling the LockDir option, make sure that you have
     tracked down and removed any copies of CVS 1.9 or older.  Such
     versions neither support LockDir, nor will give an error
     indicating that they don't support it.  The result, if this is
     allowed to happen, is that some CVS users will put the locks one
     place, and others will put them another place, and therefore the
     repository could become corrupted.  CVS 1.10 does not support
     LockDir but it will print a warning if run on a repository with
     LockDir enabled.

`LogHistory=VALUE'
     Control what is logged to the `CVSROOT/history' file (*note
     history::).  Default of `TOEFWUPCGMAR' (or simply `all') will log
     all transactions.  Any subset of the default is legal.  (For
     example, to only log transactions that modify the `*,v' files, use
     `LogHistory=TMAR'.)  To disable history logging completely, use
     `LogHistory='.

`MaxCommentLeaderLength=LENGTH'
     Set to some length, in bytes, where a trailing `k', `M', `G', or
     `T' causes the preceding nubmer to be interpreted as kilobytes,
     megabytes, gigabytes, or terrabytes, respectively, will cause
     `$Log$' keywords (*note Keyword substitution::), with more than
     LENGTH bytes preceding it on a line to be ignored (or to fall back
     on the comment leader set in the RCS archive file - see
     `UseArchiveCommentLeader' below).  Defaults to 20 bytes to allow
     checkouts to proceed normally when they include binary files
     containing `$Log$' keywords and which users have neglected to mark
     as binary.

`MinCompressionLevel=VALUE'
`MaxCompressionLevel=VALUE'
     Restricts the level of compression used by the CVS server to a
     VALUE between 0 and 9.  VALUEs 1 through 9 are the same ZLIB
     compression levels accepted by the `-z' option (*note Global
     options::), and 0 means no compression.  When one or both of these
     keys are set and a client requests a level outside the specified
     range, the server will simply use the closest permissable level.
     Clients will continue compressing at the level requested by the
     user.

     The exception is when level 0 (no compression) is not available
     and the client fails to request any compression.  The CVS server
     will then exit with an error message when it becomes apparent that
     the client is not going to request compression.  This will not
     happen with clients version 1.12.13 and later since these client
     versions allow the server to notify them that they must request
     some level of compression.

`PrimaryServer=CVSROOT'
     When specified, and the repository specified by CVSROOT is not the
     one currently being accessed, then the server will turn itself
     into a transparent proxy to CVSROOT for write requests.  The
     HOSTNAME configured as part of CVSROOT must resolve to the same
     string returned by the `uname' command on the primary server for
     this to work.  Host name resolution is performed via some
     combination of `named', a broken out line from `/etc/hosts', and
     the Network Information Service (NIS or YP), depending on the
     configuration of the particular system.

     Only the `:ext:' method is currently supported for primaries
     (actually, `:fork:' is supported as well, but only for testing -
     if you find another use for accessing a primary via the `:fork:'
     method, please send a note to <bug-cvs@nongnu.org> about it).  See
     *Note Write proxies:: for more on configuring and using write
     proxies.

`RCSBIN=BINDIR'
     For CVS 1.9.12 through 1.9.18, this setting told CVS to look for
     RCS programs in the BINDIR directory.  Current versions of CVS do
     not run RCS programs; for compatibility this setting is accepted,
     but it does nothing.

`RereadLogAfterVerify=VALUE'
     Modify the `commit' command such that CVS will reread the log
     message after running the program specified by `verifymsg'.  VALUE
     may be one of `yes' or `always', indicating that the log message
     should always be reread; `no' or `never', indicating that it
     should never be reread; or VALUE may be `stat', indicating that
     the file should be checked with the file system `stat()' function
     to see if it has changed (see warning below) before rereading.
     The default value is `always'.

     *Note_ the `stat' mode can cause CVS to pause for up to one extra
     second per directory committed.  This can be less IO and CPU
     intensive but is not recommended for use with large repositories*

     *Note verifymsg::, for more information on how verifymsg may be
     used.

`SystemAuth=VALUE'
     If VALUE is `yes', then pserver should check for users in the
     system's user database if not found in `CVSROOT/passwd'.  If it is
     `no', then all pserver users must exist in `CVSROOT/passwd'.  The
     default is `yes'.  For more on pserver, see *Note Password
     authenticated::.

`TmpDir=PATH'
     Specify PATH as the directory to create temporary files in.  *Note
     Global options::, for more on setting the path to the temporary
     directory.  This option first appeared with CVS release 1.12.13.

`TopLevelAdmin=VALUE'
     Modify the `checkout' command to create a `CVS' directory at the
     top level of the new working directory, in addition to `CVS'
     directories created within checked-out directories.  The default
     value is `no'.

     This option is useful if you find yourself performing many
     commands at the top level of your working directory, rather than
     in one of the checked out subdirectories.  The `CVS' directory
     created there will mean you don't have to specify `CVSROOT' for
     each command.  It also provides a place for the `CVS/Template'
     file (*note Working directory storage::).

`UseArchiveCommentLeader=VALUE'
     Set to `true', if the text preceding a `$Log$' keyword is found to
     exceed `MaxCommentLeaderLength' (above) bytes, then the comment
     leader set in the RCS archive file (*note admin::), if any, will
     be used instead.  If there is no comment leader set in the archive
     file or VALUE is set to `false', then the keyword will not be
     expanded (*note Keyword list::).  To force the comment leader in
     the RCS archive file to be used exclusively (and `$Log$' expansion
     skipped in files where the comment leader has not been set in the
     archive file), set VALUE and set `MaxCommentLeaderLength' to `0'.

`UseNewInfoFmtStrings=VALUE'
     Specify whether CVS should support the new or old command line
     template model for the commit support files (*note commit files::).
     This configuration variable began life in deprecation and is only
     here in order to give people time to update legacy repositories to
     use the new format string syntax before support for the old syntax
     is removed.  For information on updating your repository to
     support the new model, please see *Note Updating Commit Files::.

     _Note that new repositories (created with the `cvs init' command)
     will have this value set to `yes', but the default value is `no'._

`UserAdminOptions=VALUE'
     Control what options will be allowed with the `cvs admin' command
     (*note admin::) for users not in the `cvsadmin' group.  The VALUE
     string is a list of single character options which should be
     allowed.  If a user who is not a member of the `cvsadmin' group
     tries to execute any `cvs admin' option which is not listed they
     will will receive an error message reporting that the option is
     restricted.

     If no `cvsadmin' group exists on the server, CVS will ignore the
     `UserAdminOptions' keyword (*note admin::).

     When not specified, `UserAdminOptions' defaults to `k'.  In other
     words, it defaults to allowing users outside of the `cvsadmin'
     group to use the `cvs admin' command only to change the default
     keyword expansion mode for files.

     As an example, to restrict users not in the `cvsadmin' group to
     using `cvs admin' to change the default keyword substitution mode,
     lock revisions, unlock revisions, and replace the log message, use
     `UserAdminOptions=klum'.


File: cvs.info,  Node: Environment variables,  Next: Compatibility,  Prev: Administrative files,  Up: Top

Appendix D All environment variables which affect CVS
*****************************************************

This is a complete list of all environment variables that affect CVS
(Windows users, please bear with this list; $VAR is equivalent to %VAR%
at the Windows command prompt).

`$CVSIGNORE'
     A whitespace-separated list of file name patterns that CVS should
     ignore. *Note cvsignore::.

`$CVSWRAPPERS'
     A whitespace-separated list of file name patterns that CVS should
     treat as wrappers. *Note Wrappers::.

`$CVSREAD'
     If this is set, `checkout' and `update' will try hard to make the
     files in your working directory read-only.  When this is not set,
     the default behavior is to permit modification of your working
     files.

`$CVSREADONLYFS'
     Turns on read-only repository mode. This allows one to check out
     from a read-only repository, such as within an anoncvs server, or
     from a CD-ROM repository.

     It has the same effect as if the `-R' command-line option is used.
     This can also allow the use of read-only NFS repositories.

`$CVSUMASK'
     Controls permissions of files in the repository.  See *Note File
     permissions::.

`$CVSROOT'
     Should contain the full pathname to the root of the CVS source
     repository (where the RCS files are kept).  This information must
     be available to CVS for most commands to execute; if `$CVSROOT' is
     not set, or if you wish to override it for one invocation, you can
     supply it on the command line: `cvs -d cvsroot cvs_command...'
     Once you have checked out a working directory, CVS stores the
     appropriate root (in the file `CVS/Root'), so normally you only
     need to worry about this when initially checking out a working
     directory.

`$CVSEDITOR'
`$EDITOR'
`$VISUAL'
     Specifies the program to use for recording log messages during
     commit.  `$CVSEDITOR' overrides `$EDITOR', which overrides
     `$VISUAL'.  See *Note Committing your changes:: for more or *Note
     Global options:: for alternative ways of specifying a log editor.

`$PATH'
     If `$RCSBIN' is not set, and no path is compiled into CVS, it will
     use `$PATH' to try to find all programs it uses.

`$HOME'

`$HOMEPATH'

`$HOMEDRIVE'
     Used to locate the directory where the `.cvsrc' file, and other
     such files, are searched.  On Unix, CVS just checks for `HOME'.
     On Windows NT, the system will set `HOMEDRIVE', for example to
     `d:' and `HOMEPATH', for example to `\joe'.  On Windows 95, you'll
     probably need to set `HOMEDRIVE' and `HOMEPATH' yourself.

`$CVS_RSH'
     Specifies the external program which CVS connects with, when
     `:ext:' access method is specified.  *note Connecting via rsh::.

`$CVS_SERVER'
     Used in client-server mode when accessing a remote repository
     using RSH.  It specifies the name of the program to start on the
     server side (and any necessary arguments) when accessing a remote
     repository using the `:ext:', `:fork:', or `:server:' access
     methods.  The default value for `:ext:' and `:server:' is `cvs';
     the default value for `:fork:' is the name used to run the client.
     *note Connecting via rsh::

`$CVS_PASSFILE'
     Used in client-server mode when accessing the `cvs login server'.
     Default value is `$HOME/.cvspass'.  *note Password authentication
     client::

`$CVS_CLIENT_PORT'
     Used in client-server mode to set the port to use when accessing
     the server via Kerberos, GSSAPI, or CVS's password authentication
     protocol if the port is not specified in the CVSROOT.  *note
     Remote repositories::

`$CVS_PROXY_PORT'
     Used in client-server mode to set the port to use when accessing a
     server via a web proxy, if the port is not specified in the
     CVSROOT.  Works with GSSAPI, and the password authentication
     protocol.  *note Remote repositories::

`$CVS_RCMD_PORT'
     Used in client-server mode.  If set, specifies the port number to
     be used when accessing the RCMD demon on the server side.
     (Currently not used for Unix clients).

`$CVS_CLIENT_LOG'
     Used for debugging only in client-server mode.  If set, everything
     sent to the server is logged into ``$CVS_CLIENT_LOG'.in' and
     everything sent from the server is logged into
     ``$CVS_CLIENT_LOG'.out'.

`$CVS_SERVER_SLEEP'
     Used only for debugging the server side in client-server mode.  If
     set, delays the start of the server child process the specified
     amount of seconds so that you can attach to it with a debugger.

`$CVS_IGNORE_REMOTE_ROOT'
     For CVS 1.10 and older, setting this variable prevents CVS from
     overwriting the `CVS/Root' file when the `-d' global option is
     specified.  Later versions of CVS do not rewrite `CVS/Root', so
     `CVS_IGNORE_REMOTE_ROOT' has no effect.

`$CVS_LOCAL_BRANCH_NUM'
     Setting this variable allows some control over the branch number
     that is assigned. This is specifically to support the local commit
     feature of CVSup. If one sets `CVS_LOCAL_BRANCH_NUM' to (say) 1000
     then branches the local repository, the revision numbers will look
     like 1.66.1000.xx. There is almost a dead-set certainty that there
     will be no conflicts with version numbers.

`$COMSPEC'
     Used under OS/2 only.  It specifies the name of the command
     interpreter and defaults to CMD.EXE.

`$TMPDIR'
     Directory in which temporary files are located.  *Note Global
     options::, for more on setting the temporary directory.

`$CVS_PID'
     This is the process identification (aka pid) number of the CVS
     process. It is often useful in the programs and/or scripts
     specified by the `commitinfo', `verifymsg', `loginfo' files.

Appendix E Compatibility between CVS Versions
*********************************************

The repository format is compatible going back to CVS 1.3.  But see
*Note Watches Compatibility::, if you have copies of CVS 1.6 or older
and you want to use the optional developer communication features.

   The working directory format is compatible going back to CVS 1.5.
It did change between CVS 1.3 and CVS 1.5.  If you run CVS 1.5 or newer
on a working directory checked out with CVS 1.3, CVS will convert it,
but to go back to CVS 1.3 you need to check out a new working directory
with CVS 1.3.

   The remote protocol is interoperable going back to CVS 1.5, but no
further (1.5 was the first official release with the remote protocol,
but some older versions might still be floating around).  In many cases
you need to upgrade both the client and the server to take advantage of
new features and bug fixes, however.

Appendix F Troubleshooting
**************************

If you are having trouble with CVS, this appendix may help.  If there
is a particular error message which you are seeing, then you can look
up the message alphabetically.  If not, you can look through the
section on other problems to see if your problem is mentioned there.

* Menu:

* Error messages::              Partial list of CVS errors

* Other problems::              Problems not readily listed by error message


File: cvs.info,  Node: Error messages,  Next: Connection,  Up: Troubleshooting

F.1 Partial list of error messages
==================================

Here is a partial list of error messages that you may see from CVS.  It
is not a complete list--CVS is capable of printing many, many error
messages, often with parts of them supplied by the operating system,
but the intention is to list the common and/or potentially confusing
error messages.

   The messages are alphabetical, but introductory text such as `cvs
update: ' is not considered in ordering them.

   In some cases the list includes messages printed by old versions of
CVS (partly because users may not be sure which version of CVS they are
using at any particular moment).

`FILE:LINE: Assertion 'TEXT' failed'
     The exact format of this message may vary depending on your
     system.  It indicates a bug in CVS, which can be handled as
     described in *Note BUGS::.

`cvs COMMAND: authorization failed: server HOST rejected access'
     This is a generic response when trying to connect to a pserver
     server which chooses not to provide a specific reason for denying
     authorization.  Check that the username and password specified are
     correct and that the `CVSROOT' specified is allowed by
     `--allow-root' in `inetd.conf'.  See *Note Password
     authenticated::.

`cvs COMMAND: conflict: removed FILE was modified by second party'
     This message indicates that you removed a file, and someone else
     modified it.  To resolve the conflict, first run `cvs add FILE'.
     If desired, look at the other party's modification to decide
     whether you still want to remove it.  If you don't want to remove
     it, stop here.  If you do want to remove it, proceed with `cvs
     remove FILE' and commit your removal.

`cannot change permissions on temporary directory'
          Operation not permitted
     This message has been happening in a non-reproducible, occasional
     way when we run the client/server testsuite, both on Red Hat Linux
     3.0.3 and 4.1.  We haven't been able to figure out what causes it,
     nor is it known whether it is specific to Linux (or even to this
     particular machine!).  If the problem does occur on other unices,
     `Operation not permitted' would be likely to read `Not owner' or
     whatever the system in question uses for the unix `EPERM' error.
     If you have any information to add, please let us know as
     described in *Note BUGS::.  If you experience this error while
     using CVS, retrying the operation which produced it should work
     fine.

`cvs [server aborted]: Cannot check out files into the repository itself'
     The obvious cause for this message (especially for
     non-client/server CVS) is that the CVS root is, for example,
     `/usr/local/cvsroot' and you try to check out files when you are
     in a subdirectory, such as `/usr/local/cvsroot/test'.  However,
     there is a more subtle cause, which is that the temporary
     directory on the server is set to a subdirectory of the root
     (which is also not allowed).  If this is the problem, set the
     temporary directory to somewhere else, for example `/var/tmp'; see
     `TMPDIR' in *Note Environment variables::, for how to set the
     temporary directory.

`cannot commit files as 'root''
     See `'root' is not allowed to commit files'.

`cannot open CVS/Entries for reading: No such file or directory'
     This generally indicates a CVS internal error, and can be handled
     as with other CVS bugs (*note BUGS::).  Usually there is a
     workaround--the exact nature of which would depend on the
     situation but which hopefully could be figured out.

`cvs [init aborted]: cannot open CVS/Root: No such file or directory'
     This message is harmless.  Provided it is not accompanied by other
     errors, the operation has completed successfully.  This message
     should not occur with current versions of CVS, but it is documented
     here for the benefit of CVS 1.9 and older.

`cvs server: cannot open /root/.cvsignore: Permission denied'
`cvs [server aborted]: can't chdir(/root): Permission denied'
     See *Note Connection::.

`cvs [checkout aborted]: cannot rename file FILE to CVS/,,FILE: Invalid argument'
     This message has been reported as intermittently happening with
     CVS 1.9 on Solaris 2.5.  The cause is unknown; if you know more
     about what causes it, let us know as described in *Note BUGS::.

`cvs [COMMAND aborted]: cannot start server via rcmd'
     This, unfortunately, is a rather nonspecific error message which
     CVS 1.9 will print if you are running the CVS client and it is
     having trouble connecting to the server.  Current versions of CVS
     should print a much more specific error message.  If you get this
     message when you didn't mean to run the client at all, you
     probably forgot to specify `:local:', as described in *Note
     Repository::.

`ci: FILE,v: bad diff output line: Binary files - and /tmp/T2a22651 differ'
     CVS 1.9 and older will print this message when trying to check in
     a binary file if RCS is not correctly installed.  Re-read the
     instructions that came with your RCS distribution and the INSTALL
     file in the CVS distribution.  Alternately, upgrade to a current
     version of CVS, which checks in files itself rather than via RCS.

`cvs checkout: could not check out FILE'
     With CVS 1.9, this can mean that the `co' program (part of RCS)
     returned a failure.  It should be preceded by another error
     message, however it has been observed without another error
     message and the cause is not well-understood.  With the current
     version of CVS, which does not run `co', if this message occurs
     without another error message, it is definitely a CVS bug (*note
     BUGS::).

`cvs [login aborted]: could not find out home directory'
     This means that you need to set the environment variables that CVS
     uses to locate your home directory.  See the discussion of `HOME',
     `HOMEDRIVE', and `HOMEPATH' in *Note Environment variables::.

`cvs update: could not merge revision REV of FILE: No such file or directory'
     CVS 1.9 and older will print this message if there was a problem
     finding the `rcsmerge' program.  Make sure that it is in your
     `PATH', or upgrade to a current version of CVS, which does not
     require an external `rcsmerge' program.

`cvs [update aborted]: could not patch FILE: No such file or directory'
     This means that there was a problem finding the `patch' program.
     Make sure that it is in your `PATH'.  Note that despite
     appearances the message is _not_ referring to whether it can find
     FILE.  If both the client and the server are running a current
     version of CVS, then there is no need for an external patch
     program and you should not see this message.  But if either client
     or server is running CVS 1.9, then you need `patch'.

`cvs update: could not patch FILE; will refetch'
     This means that for whatever reason the client was unable to apply
     a patch that the server sent.  The message is nothing to be
     concerned about, because inability to apply the patch only slows
     things down and has no effect on what CVS does.

`dying gasps from SERVER unexpected'
     There is a known bug in the server for CVS 1.9.18 and older which
     can cause this.  For me, this was reproducible if I used the `-t'
     global option.  It was fixed by Andy Piper's 14 Nov 1997 change to
     src/filesubr.c, if anyone is curious.  If you see the message, you
     probably can just retry the operation which failed, or if you have
     discovered information concerning its cause, please let us know as
     described in *Note BUGS::.

`end of file from server (consult above messages if any)'
     The most common cause for this message is if you are using an
     external `rsh' program and it exited with an error.  In this case
     the `rsh' program should have printed a message, which will appear
     before the above message.  For more information on setting up a
     CVS client and server, see *Note Remote repositories::.

`cvs [update aborted]: EOF in key in RCS file FILE,v'
`cvs [checkout aborted]: EOF while looking for end of string in RCS file FILE,v'
     This means that there is a syntax error in the given RCS file.
     Note that this might be true even if RCS can read the file OK; CVS
     does more error checking of errors in the RCS file.  That is why
     you may see this message when upgrading from CVS 1.9 to CVS 1.10.
     The likely cause for the original corruption is hardware, the
     operating system, or the like.  Of course, if you find a case in
     which CVS seems to corrupting the file, by all means report it,
     (*note BUGS::).  There are quite a few variations of this error
     message, depending on exactly where in the RCS file CVS finds the
     syntax error.

`cvs commit: Executing 'mkmodules''
     This means that your repository is set up for a version of CVS
     prior to CVS 1.8.  When using CVS 1.8 or later, the above message
     will be preceded by

          cvs commit: Rebuilding administrative file database

     If you see both messages, the database is being rebuilt twice,
     which is unnecessary but harmless.  If you wish to avoid the
     duplication, and you have no versions of CVS 1.7 or earlier in
     use, remove `-i mkmodules' every place it appears in your `modules'
     file.  For more information on the `modules' file, see *Note
     modules::.

`missing author'
     Typically this can happen if you created an RCS file with your
     username set to empty.  CVS will, bogusly, create an illegal RCS
     file with no value for the author field.  The solution is to make
     sure your username is set to a non-empty value and re-create the
     RCS file.

`cvs [checkout aborted]: no such tag TAG'
     This message means that CVS isn't familiar with the tag TAG.
     Usually the root cause is that you have mistyped a tag name.
     Ocassionally this can also occur because the users creating tags
     do not have permissions to write to the `CVSROOT/val-tags' file
     (*note File permissions::, for more).

     Prior to CVS version 1.12.10, there were a few relatively obscure
     cases where a given tag could be created in an archive file in the
     repository but CVS would require the user to try a few other CVS
     commands involving that tag until one was found whch caused CVS to
     update the `val-tags' file, at which point the originally failing
     command would begin to work.  This same method can be used to
     repair a `val-tags' file that becomes out of date due to the
     permissions problem mentioned above.  This updating is only
     required once per tag - once a tag is listed in `val-tags', it
     stays there.

     Note that using `tag -f' to not require tag matches did not and
     does not override this check (*note Common options::).

`*PANIC* administration files missing'
     This typically means that there is a directory named CVS but it
     does not contain the administrative files which CVS puts in a CVS
     directory.  If the problem is that you created a CVS directory via
     some mechanism other than CVS, then the answer is simple, use a
     name other than CVS.  If not, it indicates a CVS bug (*note
     BUGS::).

`rcs error: Unknown option: -x,v/'
     This message will be followed by a usage message for RCS.  It
     means that you have an old version of RCS (probably supplied with
     your operating system), as well as an old version of CVS.  CVS
     1.9.18 and earlier only work with RCS version 5 and later; current
     versions of CVS do not run RCS programs.

`cvs [server aborted]: received broken pipe signal'
     This message can be caused by a loginfo program that fails to read
     all of the log information from its standard input.  If you find
     it happening in any other circumstances, please let us know as
     described in *Note BUGS::.

`'root' is not allowed to commit files'
     When committing a permanent change, CVS makes a log entry of who
     committed the change.  If you are committing the change logged in
     as "root" (not under "su" or other root-priv giving program), CVS
     cannot determine who is actually making the change.  As such, by
     default, CVS disallows changes to be committed by users logged in
     as "root".  (You can disable this option by passing the
     `--enable-rootcommit' option to `configure' and recompiling CVS.
     On some systems this means editing the appropriate `config.h' file
     before building CVS.)

`cvs [server aborted]: Secondary out of sync with primary!'
     This usually means that the version of CVS running on a secondary
     server is incompatible with the version running on the primary
     server (*note Write proxies::).  This will not occur if the client
     supports redirection.

     It is not the version number that is significant here, but the
     list of supported requests that the servers provide to the client.
     For example, even if both servers were the same version, if the
     secondary was compiled with GSSAPI support and the primary was not,
     the list of supported requests provided by the two servers would
     be different and the secondary would not work as a transparent
     proxy to the primary.  Conversely, even if the two servers were
     radically different versions but both provided the same list of
     valid requests to the client, the transparent proxy would succeed.

`Terminated with fatal signal 11'
     This message usually indicates that CVS (the server, if you're
     using client/server mode) has run out of (virtual) memory.
     Although CVS tries to catch the error and issue a more meaningful
     message, there are many circumstances where that is not possible.
     If you appear to have lots of memory available to the system, the
     problem is most likely that you're running into a system-wide
     limit on the amount of memory a single process can use or a
     similar process-specific limit.  The mechanisms for displaying and
     setting such limits vary from system to system, so you'll have to
     consult an expert for your particular system if you don't know how
     to do that.

`Too many arguments!'
     This message is typically printed by the `log.pl' script which is
     in the `contrib' directory in the CVS source distribution.  In
     some versions of CVS, `log.pl' has been part of the default CVS
     installation.  The `log.pl' script gets called from the `loginfo'
     administrative file.  Check that the arguments passed in `loginfo'
     match what your version of `log.pl' expects.  In particular, the
     `log.pl' from CVS 1.3 and older expects the log file as an
     argument whereas the `log.pl' from CVS 1.5 and newer expects the
     log file to be specified with a `-f' option.  Of course, if you
     don't need `log.pl' you can just comment it out of `loginfo'.

`cvs [update aborted]: unexpected EOF reading FILE,v'
     See `EOF in key in RCS file'.

`cvs [login aborted]: unrecognized auth response from SERVER'
     This message typically means that the server is not set up
     properly.  For example, if `inetd.conf' points to a nonexistent
     cvs executable.  To debug it further, find the log file which
     inetd writes (`/var/log/messages' or whatever inetd uses on your
     system).  For details, see *Note Connection::, and *Note Password
     authentication server::.

`cvs commit: Up-to-date check failed for `FILE''
     This means that someone else has committed a change to that file
     since the last time that you did a `cvs update'.  So before
     proceeding with your `cvs commit' you need to `cvs update'.  CVS
     will merge the changes that you made and the changes that the
     other person made.  If it does not detect any conflicts it will
     report `M FILE' and you are ready to `cvs commit'.  If it detects
     conflicts it will print a message saying so, will report `C FILE',
     and you need to manually resolve the conflict.  For more details
     on this process see *Note Conflicts example::.

`Usage:	diff3 [-exEX3 [-i | -m] [-L label1 -L label3]] file1 file2 file3'
          Only one of [exEX3] allowed
     This indicates a problem with the installation of `diff3' and
     `rcsmerge'.  Specifically `rcsmerge' was compiled to look for GNU
     diff3, but it is finding unix diff3 instead.  The exact text of
     the message will vary depending on the system.  The simplest
     solution is to upgrade to a current version of CVS, which does not
     rely on external `rcsmerge' or `diff3' programs.

`warning: unrecognized response `TEXT' from cvs server'
     If TEXT contains a valid response (such as `ok') followed by an
     extra carriage return character (on many systems this will cause
     the second part of the message to overwrite the first part), then
     it probably means that you are using the `:ext:' access method
     with a version of rsh, such as most non-unix rsh versions, which
     does not by default provide a transparent data stream.  In such
     cases you probably want to try `:server:' instead of `:ext:'.  If
     TEXT is something else, this may signify a problem with your CVS
     server.  Double-check your installation against the instructions
     for setting up the CVS server.

`cvs commit: [TIME] waiting for USER's lock in DIRECTORY'
     This is a normal message, not an error.  See *Note Concurrency::,
     for more details.

`cvs commit: warning: editor session failed'
     This means that the editor which CVS is using exits with a nonzero
     exit status.  Some versions of vi will do this even when there was
     not a problem editing the file.  If so, point the `CVSEDITOR'
     environment variable to a small script such as:

          #!/bin/sh
          vi $*
          exit 0

`cvs update: warning: FILE was lost'
     This means that the working copy of FILE has been deleted but it
     has not been removed from CVS.  This is nothing to be concerned
     about, the update will just recreate the local file from the
     repository.  (This is a convenient way to discard local changes to
     a file: just delete it and then run `cvs update'.)

`cvs update: warning: FILE is not (any longer) pertinent'
     This means that the working copy of FILE has been deleted, it has
     not been removed from CVS in the current working directory, but it
     has been removed from CVS in some other working directory.  This
     is nothing to be concerned about, the update would have removed
     the local file anyway.

F.2 Trouble making a connection to a CVS server
===============================================

This section concerns what to do if you are having trouble making a
connection to a CVS server.  If you are running the CVS command line
client running on Windows, first upgrade the client to CVS 1.9.12 or
later.  The error reporting in earlier versions provided much less
information about what the problem was.  If the client is non-Windows,
CVS 1.9 should be fine.

   If the error messages are not sufficient to track down the problem,
the next steps depend largely on which access method you are using.

`:ext:'
     Try running the rsh program from the command line.  For example:
     "rsh servername cvs -v" should print CVS version information.  If
     this doesn't work, you need to fix it before you can worry about
     CVS problems.

`:server:'
     You don't need a command line rsh program to use this access
     method, but if you have an rsh program around, it may be useful as
     a debugging tool.  Follow the directions given for :ext:.

`:pserver:'
     Errors along the lines of "connection refused" typically indicate
     that inetd isn't even listening for connections on port 2401
     whereas errors like "connection reset by peer", "received broken
     pipe signal", "recv() from server: EOF", or "end of file from
     server" typically indicate that inetd is listening for connections
     but is unable to start CVS (this is frequently caused by having an
     incorrect path in `inetd.conf' or by firewall software rejecting
     the connection).  "unrecognized auth response" errors are caused
     by a bad command line in `inetd.conf', typically an invalid option
     or forgetting to put the `pserver' command at the end of the line.
     Another less common problem is invisible control characters that
     your editor "helpfully" added without you noticing.

     One good debugging tool is to "telnet servername 2401".  After
     connecting, send any text (for example "foo" followed by return).
     If CVS is working correctly, it will respond with

          cvs [pserver aborted]: bad auth protocol start: foo

     If instead you get:

          Usage: cvs [cvs-options] command [command-options-and-arguments]
          ...

     then you're missing the `pserver' command at the end of the line
     in `inetd.conf'; check to make sure that the entire command is on
     one line and that it's complete.

     Likewise, if you get something like:

          Unknown command: `pserved'

          CVS commands are:
                  add          Add a new file/directory to the repository
          ...

     then you've misspelled `pserver' in some way.  If it isn't
     obvious, check for invisible control characters (particularly
     carriage returns) in `inetd.conf'.

     If it fails to work at all, then make sure inetd is working right.
     Change the invocation in `inetd.conf' to run the echo program
     instead of cvs.  For example:

          2401  stream  tcp  nowait  root /bin/echo echo hello

     After making that change and instructing inetd to re-read its
     configuration file, "telnet servername 2401" should show you the
     text hello and then the server should close the connection.  If
     this doesn't work, you need to fix it before you can worry about
     CVS problems.

     On AIX systems, the system will often have its own program trying
     to use port 2401.  This is AIX's problem in the sense that port
     2401 is registered for use with CVS.  I hear that there is an AIX
     patch available to address this problem.

     Another good debugging tool is the `-d' (debugging) option to
     inetd.  Consult your system documentation for more information.

     If you seem to be connecting but get errors like:

          cvs server: cannot open /root/.cvsignore: Permission denied
          cvs [server aborted]: can't chdir(/root): Permission denied

     then you probably haven't specified `-f' in `inetd.conf'.  (In
     releases prior to CVS 1.11.1, this problem can be caused by your
     system setting the `$HOME' environment variable for programs being
     run by inetd.  In this case, you can either have inetd run a shell
     script that unsets `$HOME' and then runs CVS, or you can use `env'
     to run CVS with a pristine environment.)

     If you can connect successfully for a while but then can't, you've
     probably hit inetd's rate limit.  (If inetd receives too many
     requests for the same service in a short period of time, it
     assumes that something is wrong and temporarily disables the
     service.)  Check your inetd documentation to find out how to
     adjust the rate limit (some versions of inetd have a single rate
     limit, others allow you to set the limit for each service
     separately.)

F.3 Other common problems
=========================

Here is a list of problems which do not fit into the above categories.
They are in no particular order.

   * On Windows, if there is a 30 second or so delay when you run a CVS
     command, it may mean that you have your home directory set to
     `C:/', for example (see `HOMEDRIVE' and `HOMEPATH' in *Note
     Environment variables::).  CVS expects the home directory to not
     end in a slash, for example `C:' or `C:\cvs'.

   * If you are running CVS 1.9.18 or older, and `cvs update' finds a
     conflict and tries to merge, as described in *Note Conflicts
     example::, but doesn't tell you there were conflicts, then you may
     have an old version of RCS.  The easiest solution probably is to
     upgrade to a current version of CVS, which does not rely on
     external RCS programs.

Appendix G Credits
******************

Roland Pesch, then of Cygnus Support <roland@wrs.com> wrote the manual
pages which were distributed with CVS 1.3.  Much of their text was
copied into this manual.  He also read an early draft of this manual
and contributed many ideas and corrections.

   The mailing-list `info-cvs' is sometimes informative. I have
included information from postings made by the following persons: David
G. Grubbs <dgg@think.com>.

   Some text has been extracted from the man pages for RCS.

   The CVS FAQ by David G. Grubbs has provided useful material.  The
FAQ is no longer maintained, however, and this manual is about the
closest thing there is to a successor (with respect to documenting how
to use CVS, at least).

   In addition, the following persons have helped by telling me about
mistakes I've made:

     Roxanne Brunskill <rbrunski@datap.ca>,
     Kathy Dyer <dyer@phoenix.ocf.llnl.gov>,
     Karl Pingle <pingle@acuson.com>,
     Thomas A Peterson <tap@src.honeywell.com>,
     Inge Wallin <ingwa@signum.se>,
     Dirk Koschuetzki <koschuet@fmi.uni-passau.de>
     and Michael Brown <brown@wi.extrel.com>.

   The list of contributors here is not comprehensive; for a more
complete list of who has contributed to this manual see the file
`doc/ChangeLog' in the CVS source distribution.

Appendix H Dealing with bugs in CVS or this manual
**************************************************

Neither CVS nor this manual is perfect, and they probably never will
be.  If you are having trouble using CVS, or think you have found a
bug, there are a number of things you can do about it.  Note that if
the manual is unclear, that can be considered a bug in the manual, so
these problems are often worth doing something about as well as
problems with CVS itself.

   * If you want someone to help you and fix bugs that you report,
     there are companies which will do that for a fee.  One such
     company is:

          Ximbiot
          319 S. River St.
          Harrisburg, PA  17104-1657
          USA
          Email: info@ximbiot.com
          Phone: (717) 579-6168
          Fax:   (717) 234-3125
          `http://ximbiot.com/'

   * If you got CVS through a distributor, such as an operating system
     vendor or a vendor of freeware CD-ROMs, you may wish to see
     whether the distributor provides support.  Often, they will provide
     no support or minimal support, but this may vary from distributor
     to distributor.

   * If you have the skills and time to do so, you may wish to fix the
     bug yourself.  If you wish to submit your fix for inclusion in
     future releases of CVS, see the file HACKING in the CVS source
     distribution.  It contains much more information on the process of
     submitting fixes.

   * There may be resources on the net which can help.  A good place to
     start is:

          `http://cvs.nongnu.org/'

     If you are so inspired, increasing the information available on
     the net is likely to be appreciated.  For example, before the
     standard CVS distribution worked on Windows 95, there was a web
     page with some explanation and patches for running CVS on Windows
     95, and various people helped out by mentioning this page on
     mailing lists or newsgroups when the subject came up.

   * It is also possible to report bugs to <bug-cvs@nongnu.org>.  Note
     that someone may or may not want to do anything with your bug
     report--if you need a solution consider one of the options
     mentioned above.  People probably do want to hear about bugs which
     are particularly severe in consequences and/or easy to fix,
     however.  You can also increase your odds by being as clear as
     possible about the exact nature of the bug and any other relevant
     information.  The way to report bugs is to send email to
     <bug-cvs@nongnu.org>.  Note that submissions to
     <bug-cvs@nongnu.org> may be distributed under the terms of the GNU
     Public License, so if you don't like this, don't submit them.
     There is usually no justification for sending mail directly to one
     of the CVS maintainers rather than to <bug-cvs@nongnu.org>; those
     maintainers who want to hear about such bug reports read
     <bug-cvs@nongnu.org>.  Also note that sending a bug report to
     other mailing lists or newsgroups is _not_ a substitute for
     sending it to <bug-cvs@nongnu.org>.  It is fine to discuss CVS
     bugs on whatever forum you prefer, but there are not necessarily
     any maintainers reading bug reports sent anywhere except
     <bug-cvs@nongnu.org>.

   People often ask if there is a list of known bugs or whether a
particular bug is a known one.  The file BUGS in the CVS source
distribution is one list of known bugs, but it doesn't necessarily try
to be comprehensive.  Perhaps there will never be a comprehensive,
detailed list of known bugs.
