Subject: v17i064: Zoo archive program, Part01/10 Newsgroups: comp.sources.unix Approved: rsalz@uunet.UU.NET Submitted-by: Rahul Dhesi <bsu-cs!dhesi@iuvax.cs.indiana.edu> Posting-number: Volume 17, Issue 64 Archive-name: zoo2/part01 The zoo archive program maintains archives of files in compressed form. Subdirectory structure can be preserved across dissimilar systems. Timezone and file attributes can be preserved. Multiple generations of the same file can be stored, and the user may specify how many generations of a file should be kept. A comment may be attached to each archived file or to the archive as a whole. Filenames to be archived may be fed from standard input or supplied as arguments. This is a posting of the (relatively) portable C source for version 2.01. It is ready for compilation under VAX/VMS 4.6, 4.3BSD, Xenix, System V Release 2 (including Microport System V/AT), and other similar systems. A system-dependent support package, which will allow this present source posting to be compiled under MS-DOS, will be posted to comp.binaries.ibm.pc separately. Binaries for AmigaDOS and MS-DOS, have appeared or will appear in appropriate newsgroups. A small, memory-efficient zoo archive extractor called "booz" has already appeared in comp.sources.misc. Rahul Dhesi UUCP: <backbones>!{iuvax,pur-ee,uunet}!bsu-cs!dhesi #! /bin/sh # This is a shell archive. Remove anything before this line, then unpack # it by saving it into a file and typing "sh file". To overwrite existing # files, type "sh file -c". You can also feed this as standard input via # unshar, or by typing "sh <file", e.g.. If this archive is complete, you # will see the following message at the end: # "End of archive 1 (of 10)." # Wrapped by rsalz@papaya.bbn.com on Thu Feb 2 18:03:55 1989 PATH=/bin:/usr/bin:/usr/ucb ; export PATH if test -f 'Changes' -a "${1}" != "-c" ; then echo shar: Will not clobber existing file \"'Changes'\" else echo shar: Extracting \"'Changes'\" $2497 characters$ sed "s/^X//" >'Changes' <<'END_OF_FILE' X X X CHANGES X X XSummary of Changes from Zoo version 1.51 to version 2.0. X X - New modifiers to the list commands permit several new output X formats. X X - Timezones are handled. X X - A bug was fixed that had made it impossible to individually update X comments for a file whose name did not correspond to MS-DOS format. X X - The shared library on the **IX PC can be used. X X - VAX/VMS is now supported reasonably well. X X - A comment may now be attached to the archive itself. X X - Extracted files can optionally be forced to overwrite existing X read-only files. X X - Extracted files will not overwrite newer existing files unless X specifically requested. X X - File attributes (lowest nine mode bits) are preserved for **IX X systems. X X - Multiple generations of the same file are supported. X X - Zoo will now act as a pure compression or uncompression filter on a X single input data stream. X X - A bug was fixed that could cause removal of a directory link by the X superuser. X X - The ability of Zoo to recover data from damaged archives is greatly X improved. X X XSummary of Changes from Zoo version 2.00 to version 2.01. X X - A bug was fixed that had caused the first generation of a file to X sometimes unexpectedly show up in archive listings. X X - A bug was fixed that had caused the MS-DOS version to silently skip X extracting files for which there was not sufficient disk space; an X error message will now be given. X X - A bug was fixed that had sometimes made it impossible to X selectively extract a file by specifying its name, even though all X files could be extracted from the archive by not specifying any X filenames. This occurred when a file had been archived on a X longer-filename system (e.g. AmigaDOS) and extraction was attempted X on a shorter-filename system (e.g. MS-DOS). X X - A change was made that will make zoo preserve the mode (file X protection) of a zoo archive when it is packed. This is effective X only if zoo is compiled to preserve and restore file attributes. X Currently this is so only for **IX systems. X X - A bug was fixed that had caused an update of an archive to not X always add all newer files. X X - Blanks around equal signs in commands given to "make" were removed X from the mk* scripts for better compatiblity with more **IX X implementations including Sun's.

When NDEBUG is not defined, many assertions in the code X get enabled and will give error messages if they fail. Recent X revisions may have made some of these assertions invalid. X Xo On systems with ints longer than 32 bits, there were some minor X portability problems reported in the past. I suggested some fixes (which X are incorporated in the current distribution) but was unable to confirm X if they worked. If you get zoo 2.0 working on a Cray, CDC, or similar X machine with very large ints, please let me know. X Xo Handling of pathnames longer than 255 characters is probably not robust X at this time. Zoo should be able to handle pathanmes of up to 510 X characters, with the filename part and the directory prefix part each X being 255 characters or less. But it will probably choke on any pathname X that is longer than 255 characters. X Xo The **IX "file" command, at least on System V Release 2 and on 4.3BSD, X can be made to recognize zoo archives.
