1Version 2.20 --> 2.21 2 3* Upgraded code from bash to version 4.3 (now uses eaccess). 4* Fixed a bug related to getgroups / sysconfig that caused Which not to see 5 more than 64 groups for a single user (thanks to Dmitry Bakshaev for finding 6 and analyzing this). 7* Build system maintenance. 8 9Version 2.19 --> 2.20 10 11* xmalloc.h included a readline header for no apparent reason. The compilation 12 failed if readline was not installed. The dependency on the readline header 13 was removed. Submitted by Tushar Teredesai. 14 15Version 2.18 --> 2.19 16 17* Upgraded code from bash to version 3.2. This DOES has influence 18 on how Which behaves under certain circumstances. 19* Support for Cygwin: Two leading slashes are now treated as 20 possibly special, because a double leading slash can have an 21 implementation-defined meaning (depending on the Operating 22 System), as is for example the case in Cygwin. 23 See http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap04.html#tag_04_11 24 This means that GNU which no longer collapses two leading slashes 25 of a path into a single slash. 26* When the environment variable HOME is not set, the home directory 27 is now read from /etc/passwd or set to '/' if no home directory 28 could be found (this now matches the tilde lib used in bash). 29* Fixed the function declaration given in README.alias 30* Added a @dircategory and @direntry to which.texi 31* Changed the license to GPLv3. 32 33Version 2.17 --> 2.18 34 35* Fixes regarding cwautomacros (maintainer build system only). 36* Improvement of 'make release' target (maintainer target). 37 38Version 2.16 --> 2.17 39 40* Add support for shells that output '{' on the same line as the 41 function name in the output of 'declare -f' (ie zsh). 42* Added support for Tandem OSS. 43* Build system now uses cwautomacros (mostly just it's autogen.sh). 44 45Version 2.15 --> 2.16 46 47* This release fixes the bug, introduced in 2.15, that files for 48 which the 'other' permission bits apply do NOT need to be readable. 49 (The confusion came from the fact that it needs to be readable 50 when it is a shell script but there is no way to find out if a 51 non-readable file is a shell script or not.) 52 The next release of bash will be using the same algorithm again, 53 and that is the only thing that really matters. This is also the 54 algorithm that most other shells use. 55 56Version 2.14 --> 2.15 57 58* Upgraded build system to work with automake 1.7.2 and autoconf 2.57. 59* Fixed search routine to skip executables that are not executable. 60 This is NOT done by all versions of bash (which is a bug). 61 The stock bash-2.0.5b thinks it is allowed to execute a file 62 when it has the eXec bit set for our group or other, but that 63 is not the case: when we own the file, the eXec bit of the *owner* 64 must be set and the group/other bits are irrelevant. And when 65 we don't own the file, but the file is in our group, then only 66 the group bit matters and not the other eXec bit. And finally, 67 when we do not own the file and the file is not in our group 68 then not only the 'other' eXec bit needs to be set, but the 69 file must be readable as well. This has been reported to the 70 maintainer of bash. For the rest, the search routine has been 71 copied/upgraded to that of bash version 2.0.5b. 72 73Version 2.13 --> 2.14 74 75* Upgraded build system to work with automake 1.5 and autoconf 2.53. 76* Upgraded --read-functions functionality to work with bash 2.0.5b. 77 78Version 2.12 --> 2.13 79 80* Support for shell functions. This version also fixes the 81 problem that the alias for `which' wasn't inherited by subshells. 82 You need to change the alias by a shell function! (The rpm does 83 this automatically). 84* Fixes for the .spec file (merged changes from RedHat 7.1) 85 Now installs the which.info file as well. 86 87Version 2.11 --> 2.12 88 89* Minor man page fix (no reason to upgrade at all thus) 90 91Version 2.10 --> 2.11 92 93* Added a texinfo file (no reason to upgrade at all thus) 94 `info' is the prefered format for documenting GNU tools. 95 96Version 2.9 --> 2.10 97 98* Buildsystem fixes (no reason to upgrade at all thus): 99 Used the correct order of calling the automake/conf utils, 100 fixed my E-mail address and added a Source: line to the rpm spec. 101 102Version 2.8 --> 2.9 103 104* Fixed compile problem in Solaris 5.6 using cc 105* Added a `--help' option 106* RPMs now add a /etc/profile.d script, automatically setting a useful alias 107 108Version 2.7 --> 2.8 109 110* aclocal.m4 was missing from the tar, resulting in 111 a build failure if autoconf isn't installed. 112 113Version 2.6 --> 2.7 114 115* Support for aliases 116* Configure/compile fix in the `tilde' directory. 117 118Version 2.5 --> 2.6 119 120* Doesn't depend on libreadline.a anymore. 121 122Version 2.4 --> 2.5 123 124* Fixed which-2.spec 125* RPMs are now available from http://www.xs4all.nl/~carlo17/which 126
