1# @(#)README 1.7 99/11/23 joerg 2 3Note: 4 5 This program requires a lot of virtual memory to run since it 6builds all of the directories in memory. The exact requirements 7depend upon a lot of things, but for Rock Ridge discs 12Mb would not 8be unreasonable. Without RockRidge and without the translation 9tables, the requirements would be considerably less. 10 11***************************** 12Notes for version 1.12 13 14 Joliet support is now complete. See the -J option. 15 16 The file scanning code is much improved - mkisofs can use multiple 17 sources of input files and merge them together to form the output 18 image. In addition, each source can be grafted at any point in the 19 iso9660 image. 20 21 The image writing code has been cleaned up to make it much easier 22 to add custom extensions. 23 24 The ADD_FILES feature has been removed as it didn't work well, 25and it was hard to figure out. The recent rearrangements in the 26file scanning code would tend to solve these issues. 27 28***************************** 29Notes for version 1.11 30 31 There is a feature which can be optionally compiled into 32mkisofs that allows you to merge arbitrary directory trees into the 33image you are creating. You need to compile with -DADD_FILES for my 34changes to take effect. Thanks to Ross Biro biro@yggdrasil.com. 35 36***************************** 37Notes for version 1.10b1 38 39 Big news is that multi-session capability is very close to being 40 done. There is still a missing interface to cdwrite that is 41 used to determine the next writable address and the sector number 42 of the last existing session. Until we get the interface to cdwrite 43 done, this is a beta version. 44 45 Bug involving DST fixed (dates are always calculated, since some 46 files may be DST and other ones would not be). 47 48 Unfortunately the notes on some of the small patches got lost. 49 50***************************** 51Notes for version 1.06 52 53 Jan-Piet Mens <jpm@mens.de> added support for the '-m' switch. This 54 allows exclusion of shell-style globs from the CDROM. 55 See manual mkisofs.8 for more information. 56 57***************************** 58Notes for version 1.05 59 60 Added support for '-r' switch. This is very similar to -R for 61Rock Ridge, but echos of the development environment are removed 62(i.e. uid/gid set to 0, and permissions of the files are canonicalized). 63Useful in applications where a distribution medium is being produced. 64 65***************************** 66Notes for version 1.04 67 68 No notes for 1.04. 69 70***************************** 71Notes for version 1.03 72 73 No notes for 1.03. 74 75***************************** 76Notes for version 1.02. 77 78 Minor bugfixes here and there. Support for compiled in 79defaults for many of the text fields in the volume header are now 80present, and there is also support for a file ".mkisofsrc" that can 81also read settings for these parameters. 82 83 A short script "Configure" was added to allow us to set up special 84compile options that depend upon the system that we are running on. 85This should help stamp out the sphaghetti-isms that were starting to grow 86up in various places in the code. 87 88 You should get more meaningful error messages if you run out of 89memory. 90 91***************************** 92Notes for version 1.1. 93 94 The big news is that SUSP CE entries are now generated for 95extremely long filenames and symlink names. This virtually guarantees 96that there is no limit (OK, well, about 600Mb) for file name lengths. 97I have tested this as well as I can, and it seems to work with linux. 98This would only be used very rarely I suspect. 99 100 Also, I believe that support for VMS is done. You must be 101careful, because only Stream-LF and FIxed length record files can be 102recorded. The rest are rejected with error messages. Perhaps I am 103being too severe here. 104 105 There is a bugfix in the sorting of entries on the disc - we 106need to stop comparing once we reach the ';' character. 107 108 There are four new options -z -d -D -l -V. Some of these tell 109mkisofs to relax some of the iso9660 restrictions, and many systems 110apparently do not really seem to mind. Use these with caution. 111 112 Some diagnostic programs to scan disc images are in the diag 113directory. These are not as portable as mkisofs, and may have some 114bugs. Still they are useful because they can check for bugs that I might 115have introduced as I add new features. 116 117***************************** 118Notes for version 1.0. 119 120 In version 1.0, the date fields in the TF fields were fixed - 121previously I was storing st_ctime as the file creation time instead of 122the file attribute change time. Thanks to Peter van der Veen for 123pointing this out. I have one slight concern with this change, 124however. The Young Minds software is definitely supplying 3 dates 125(creation, modification and access), and I would strongly suspect that 126they are incorrectly putting the file attribute change time in the 127file creation slot. I would be curious to see how the different RRIP 128filesystems treat this. Anyway, this is something to keep in the back 129of your mind. 130 131 The symlink handling was not quite correct in 0.99 - this is 132now fixed. Only some systems seemed to have been affected by this bug. 133 134 A command line option is now present to allow you to 135specifically exclude certain files from the distribution. 136 137 The case where you do not have permissions to read a directory 138is now handled better by mkisofs. The directory that cannot be opened 139is converted into a zero-length file, and processing continues normally. 140 141 A few portability things have been fixed (hopefully). 142 143
