Bugs (real and/or imagined):
---------------------------
- Watcom C getch() broken; password echos (reported to Watcom by K.U.Rommel)
- VMS docs out of date
- Amiga port broken?
- VMS unzip no longer sets permissions correctly
- Macintosh file attributes not interpreted correctly (both unzip, zipinfo)
- errno declaration conflicts with several compilers' definitions: change
logic so undeclared by default? How many systems affected?
- (?) add ifndef MODERN around srand, rand prototypes in crypt.c? [James
Birdsall, 4/23]
- pkbug error: zipfile with incorrect csize and/or ucsize--check for end of
compressed (csize) data in uncompression routines:
unimplod.c: while ((!zipeof) && ((outpos + outcnt) < ucsize)) {
unreduce.c: while (((outpos + outcnt) < ucsize) && (!zipeof)) {
(James Birdsall, Mark, bottom of BUGS.long)
- if PK signature not found, append .zip and try again without error
messages (Jean-loup, others, bottom of BUGS.long)
- disk full: a few files clear some pointer; continuing beyond "Continue?"
prompt, regardless of answer, kills unzip--stack too small? (doesn't seem
to matter) Bug in MSC write() function? Subsequent write code isn't any
different from -t option, so unlikely to be bug in uncompress routines...
File descriptor bad/close() failure? (workaround: ^C at prompt)
- textfile conversions on a PC system add extra CR to lines which already have
CR/LF combo; other directions probably don't work, either (Mac/Unix/...):
rewrite "dos2unix" and make general
- compressed symlinks are allowed: revise symlink code
- fix "no errors detected" message for errors occurring *before* extract_or_
test_files(); count errors? differentiate between errors and warnings?
Features (possible and/or definite):
-----------------------------------
- add -x "exclude following files" option to unzip and zipinfo
- make use of FILE_IO_C and similar defines to avoid including unnecessary
header files in various modules (unzip.h)
- add "near" to global vars [Steve Salisbury, 4/21]
- construct CRC table dynamically? [Jean-loup, 5/12]
- when listing filenames, use '?' for non-printables? [Thomas Wolff, 6/1]
- modify to decompress input stream if part of a pipe, but continue using
central directory if not (BIG job!)--extended local header capability
- need zipinfo target(s) in makefile.dos
- build in capability to check text/binary type and warn if -a (if version
< 1.1 and not made on DOS--i.e., not early Info-ZIP versions)
- allow wildcards in zipfile name (loop through each one)
- test/incorporate Martin Schulz optimization patch (still useful?)
- add -oo option (overwrite and override): no user queries (if bad password,
skip file; if disk full, take default action; if VMS special on non-VMS,
unpack anyway; etc.)
- add -Q[Q[Q]] option (quiet mode on comments, cautions, warnings and errors):
forget -oo, or make synonym? Default level -Q?
- incorporate Atari patches
- rewrite mapname()
- modify set_file_time routines to share common code (macro?)
- add zipinfo "in-depth" option? (check local vs. central filenames, etc.)
- create zipcat program to concatenate zipfiles
- create zipfix program to rebuild/salvage damaged zipfiles
- assembly-language routines?
- add -i (ignore case for internal filename match) option? (maybe not)
- CP/M version (Jeffery Foy)
- VM/CMS version (Chua Kong Sian, others)
- put man pages in more "proper" nroff format
- add OS/2 .INF format helpfiles for UnZip and ZipInfo
