- This is a summary of changes from Zoo version 1.41 to version 1.51.
-
- - Zoo 1.41 always deleted an archived file if another file with the
- same name was added to the archive, even if the two files had
- different directory prefixs. Zoo 1.51 works as follows. If Zoo is
- storing full pathnames during addition, then it deletes the old
- file only if the old and new files have identical pathnames. If
- Zoo is not storing pathnames but only filenames, then it deletes
- the old file if the old and new files have the same filename,
- regardless of their pathnames.
-
- - If a supplied argument matches no files, Zoo will now give an error
- message. Previous versions gave an error message only if no files
- matched any argument. However, this does not currently affect the
- status code returned on exit.
-
- - Zoo 1.41 did not archive a file whose filename (without path
- prefix) was the same as the name of a subdirectory in the current
- directory. Similarly an archive of the form "xyz.zoo" was ignored
- by the list command if a subdirectory "xyz" existed in the current
- directory. This bug is now fixed.
-
- - Wildcard handling is now uniform across all operating systems. "*"
- matches zero or more characters and "?" matches any one character.
- The dot is no longer special. Thus "zoo a xyz *" will always add
- all files to archive xyz.zoo on all systems.
-
- - The new switch 'I' causes Zoo to read names of files to be archived
- from standard input.
-
- - The Novice commands no longer store the directory prefix for any
- filename. Thus Zoo's Novice commands simulate the behavior of
- other archive programs.
-
- - A bug was fixed that had caused the file date and time not to be
- restored when full path was restored.
-
- - A bug was fixed that had caused the directory prefix not to be
- saved when a filename had no dot in it but directory prefix
- contained a dot.
-
- - A bug was fixed that had caused the totals line to be corrupted in
- the "La" command.
-
- - Packing now keeps the archive in the same directory. Users with
- limited disk space can still pack an archive from one disk to
- another by using the . switch.
-
- - A bug related to incorrect handling of timezones, when daylight
- savings is in effect, was fixed.
