Change Log

All notable changes to the project are documented in this file.

[v2.11][UNRELEASED]

Changes

  • Import v2.10 (v2.1) from Ibiblio http://www.ibiblio.org/pub/packages/ccic/software/unix/utils/
  • Import Debian patches
  • Massive code cleanup, incl. reindentation to Linux KNF
  • Import Martin Schoenert's unzoo and John. W. Linville's patches
  • Add unzoo.1 man page
  • Make ooz and fiz optional in build, see configure script
  • Make unzoo possible to disable from build
  • Add basic unit test
  • Use configure script to detect and build for correct host

Fixes

  • Proper fix to Debian 03-fix-manage-archive-under-AMD64.patch; use proper 32-bit data types for zoo file header in RAM. The disk format is marshalled, so not affected.
  • Make ooz build again

v2.1 - Date Unknown

Changes

  • On some systems, extraction of files using the older (default) compression method is greatly speeded up.
  • Extended multiscreen help is available.
  • The default archive-wide generation limit, when generations are enabled, is 3.

Fixes

  • Memory allocation is improved, so that the MS-DOS version will not prematurely abort when updating a large archive.
  • The VAX/VMS version preserves file timestamps during extraction.

v2.01 - Date Unknown

Changes

  • A change was made that will make zoo preserve the mode (file protection) of a zoo archive when it is packed. This is effective only if zoo is compiled to preserve and restore file attributes. Currently this is so only for **IX systems.

  • Blanks around equal signs in commands given to "make" were removed from the mk* scripts for better compatibility with more **IX implementations including Sun's.

  • Compression is now greatly improved if the "h" option is used.

  • The default behavior is to preserve full pathnames during extraction.

Fixes

  • A bug was fixed that had caused the first generation of a file to sometimes unexpectedly show up in archive listings.

  • A bug was fixed that had caused the MS-DOS version to silently skip files that could not be extracted because of insufficient disk space.

  • A bug was fixed that had sometimes made it impossible to selectively extract a file by specifying its name, even though all files could be extracted from the archive by not specifying any filenames. This occurred when a file had been archived on a longer-filename system (e.g. AmigaDOS) and extraction was attempted on a shorter-filename system (e.g. MS-DOS).

  • A bug was fixed that had caused an update of an archive to not always add all newer files.

v2.0 - Date Unknown

Changes

  • A comment may now be attached to the archive itself.

  • New option OO allows forced overwriting of read-only files.

  • zoo no longer extracts a file if a newer copy already exists on disk; the S option overrides this.

  • File attributes are preserved for **IX systems.

  • Multiple generations of the same file are supported.

  • zoo now act as a compression or decompression filter on a stream of data and will use a CRC value to check the integrity of a data stream that is uncompressed.

Fixes

  • A bug was fixed that caused removal of a directory link if files were moved to an archive by the superuser on a **IX system.

  • The data recovery modifier @ was greatly enhanced. Self-extracting archives created for MS-DOS systems can now be extracted by zoo on any system with help from fiz(1).

v1.71 - Date unknown

Changes

  • New modifiers to the list commands permit optional suppression of header and trailer information, inclusion of directory names in columnized listings, and fast one-column listings.

  • Timezones are handled.

  • zoo can now use of the shared library on the **IX PC.

  • VAX/VMS is now supported reasonably well.

Fixes

  • A bug was fixed that had made it impossible to individually update comments for a file whose name did not correspond to MS-DOS format.
