Bogus bugs (not our fault!):
|
||
|
|
---------------------------
|
||
|
|
|
||
|
|
By far THE BIGGEST source of bug reports to Info-ZIP/zip-bugs is the
|
||
|
|
incorrect transfer of zipfiles (or of the UnZip executable itself).
|
||
|
|
ALWAYS TRANSFER IN BINARY MODE! This includes ftp transfers and *both*
|
||
|
|
ends of a Kermit connection ("set file type binary"). If your copy
|
||
|
|
isn't exactly the same size as the original, you made a mistake.
|
||
|
|
|
||
|
|
Another common source of errors such as "compression method 8 not sup-
|
||
|
|
ported" is the existence of an old version of UnZip somewhere in your
|
||
|
|
path. Make sure you're using the version you think you're using; give
|
||
|
|
the full path explicitly if necessary. Executing "unzip" without any
|
||
|
|
options will print a help screen, at the top of which is the UnZip
|
||
|
|
version number and release date; and executing "unzip -v" without any
|
||
|
|
zipfile or other options will give information about what compiler was
|
||
|
|
used, the target operating system, any special UnZip options, and the
|
||
|
|
date of compilation--only for version 5.11 and later, though! (Also,
|
||
|
|
under Unix C shell and some Bourne shells, "which unzip" will print
|
||
|
|
the path of the unzip you're actually using. Under OS/2 and MS-DOS,
|
||
|
|
whch21gr.zip [on Simtel mirror sites] will do the same thing; in addi-
|
||
|
|
tion, "which -a unzip" will show *all* copies of "unzip" in your path.)

Bugs (real and/or imagined):
|
||
|
|
---------------------------
|
||
|
|
|
||
|
|
- [OS/2 DLL] when trying to use the REXX function UzUnZipToStem to extract a
|
||
|
|
file with `&' in its name, the DLL crashes (but UzUnZipToVar still works)
|
||
|
|
[Daniel H, 961215]
|
||
|
|
- UnZip has problems with archives bigger than 2GB; it may print "note: didn't
|
||
|
|
find end-of-central-dir signature at end of central dir" (harmless) or
|
||
|
|
may not be able to seek to member files [James Lemley 970107, Iris Spaniol
|
||
|
|
970206, ...]
|
||
|
|
|
||
|
|
Fixed with Zip64 support in UnZip 6.0
|
||
|
|
|
||
|
|
- fix overwrite behavior: hidden/system problems?; etc.
|
||
|
|
- 32-bit DOS UnZip still unable to set volume labels?
|
||
|
|
- 32-bit DOS UnZip under OS/2 doesn't extract all wildcard zipfiles?
|
||
|
|
[DOS box: unzip386 (ver 5.12) x:\32bit\unix\emx09a\*.zip, Hobbes 3/95]
|
||
|
|
- 32-bit DOS UnZip under OS/2 doesn't set timestamp when overwriting files
|
||
|
|
on HPFS partition? (go32 and pmode/w both; emx/rsx OK) [Eberhard Mattes
|
||
|
|
950726]
|
||
|
|
- USE_FWRITE still causes occasional CRC errors when extracting on Pyramid?
|
||
|
|
[Kevin Fritz 931102]
|
||
|
|
- still NT/W95 bug with "unzip -v d:*.zip" not matching properly? [Steve S
|
||
|
|
940527]
|
||
|
|
980427: bug no longer exists, Opendir() must have been corrected by someone
|
||
|
|
|
||
|
|
- when ^Z received in no-echo mode, echo is not restored (works OK if
|
||
|
|
resume, however)
|
||
|
|
- signal() handler disabled after first use with one of BSD/SysV?
|
||
|
|
- MKS Korn shell: unzip assumes the MKS-style command-line environment
|
||
|
|
options are relevant to it, but this is not the case if unzip was called
|
||
|
|
by another program (e.g., from a .BAT file). A fix for this exists for
|
||
|
|
Borland compilers but not for MSC, Watcom, djgpp, etc.
|
||
|
|
- OS/2: for paths with one long component, the .LONGNAME EA may be saved for
|
||
|
|
all components (waste of disk space): how to check??
|
||
|
|
- VMS: for extracting to other directories, only the VMS-style "-d [.foo]"
|
||
|
|
format is accepted; "-d foo" should also be allowed. Long filenames are
|
||
|
|
not automatically truncated to 39.39.
|
||
|
|
- Novell Netware: Netware drives may clear the archive bit on extracted
|
||
|
|
files under OS/2 and/or MS-DOS. UnZip always *tries* to set the archive
|
||
|
|
bit, however. [pynq@uchicago, 940527]
|
||
|
|
- DEC Ultrix: on long zipfiles, unzip will sometimes fail (bad CRC, not always
|
||
|
|
reproducible); this is apparently due either to a hardware bug (cache mem)
|
||
|
|
or OS bug (page faults?) [Igor, Jean-loup, bottom of BUGS.long]
|
||
|
|
- funzip/more/decryption/no-echo bug: race condition(?) causes terminal to
|
||
|
|
be "reset" to no-echo state
|
||
|
|
- Macintosh (100200), Atari (020000) external file attributes not interpreted
|
||
|
|
correctly (both unzip and zipinfo)
|
||
|
|
- pkbug error: zipfile with incorrect csize and/or ucsize--check for end of
|
||
|
|
compressed (csize) data in uncompression routines:
|
||
|
|
unreduce.c: while (((outpos + outcnt) < ucsize) && (!zipeof)) {
|
||
|
|
[James Birdsall, Mark, bottom of BUGS.long]
|
||
|
|
- OS/2: directory EAs not restored if directory exists [Kai Uwe, KG27515@uark]
|
||
|
|
(subsequent note: no way to determine which EAs are newer ==> cannot
|
||
|
|
restore without user input)
|
||
|
|
(update: as of UnZip 5.30, option -o forces restoring of directory EAs)
|
||
|
|
- MS-DOS: Borland executables don't allow other than 80-column, 25/43/50-line
|
||
|
|
screen modes (Borland bug) [Michael Stillwell]
