- 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, ...]
- - 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:32bitunixemx09a*.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]
- - 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)
- - MS-DOS: Borland executables don't allow other than 80-column, 25/43/50-line
- screen modes (Borland bug) [Michael Stillwell]
