CHANGES
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.
