- extract.c, fileio.c, process.c: removed unneeded (FILE *) type-casts in
calls to zfseeko() and zftello() [Chr. Spieler]
- extract.c, list.c, zipinfo.c, unzpriv.h: use symbolic constants for the
16-bit and 64-bit masks in the checks for zip entry count consistency
[Steven M. Schweda, Chr. Spieler]
- process.c: reorganized the extended Zip filesize-checking code (for > 2GB

extraction root dir from do_seekable() further down the call tree into
extract_or_test_files() [Chr. Spieler]
unzip-6.0/History.600 view on Meta::CPAN
branch for the "input time stamp cannot be converted to local time" case
[Steve Youngs]
- added new compression methods and e.f. IDs from PKWARE Appnote 6.3.0 as of
2006-09-29 [Chr. Spieler]
- extract.c - extract_or_test_files(): remove dead branch in the code section
handling archive test summary messages. [Chr. Spieler]
- fileio.c - zstrnicmp(): added (uch) typecasts to comparison, to improve
"compatibility" with "extended ASCII characters". [Chr. Spieler]
- vms: use CRTL-supplied function strncasecmp() for STRNICMP() when available.
[Steven M. Schweda, Chr. Spieler]
- vms/vms.c, vms/vms.h: for better synchronisation with upcoming UnZip 6 code,
the macros for masking the "ODS2 vs. ODS5" support differences have been
cleanded up and ported back to the 5.5x VMS code. [Chr. Spieler]
- ubz2err.c: new source file to isolate the bzip2 "fatal error" callback
routine in its own module; this allows easy replacement of this routine
when the UnZip package is used as a static library (e.g. for WiZ with
bzip2 support). [Chr. Spieler]
- general: added new ubz2err.c module to the make procedures of ports that
(might) support bzip2. [Chr. Spieler]
- crypt.c: optimized crypt-keys handling for Big-Endian systems using the
optimized CRC32 code by introducing a local copy of the crc32 table
unzip-6.0/History.600 view on Meta::CPAN
way to other OS (Win32, Unix). (not yet working, requires more work to
get completed and debugged...). [Chr. Spieler]
- win32/makefile.bc, win32/makefile.gcc, win32/makefile.wat: completed clean
target functionality. [Chr. Spieler]
- win32, wince: added workaround to keep Visual Studio 2005 C compiler quiet.
[N.N.]
- unzpriv.h, extract.c, list.c, zipinfo.c: added "WavPack" (supported by
WinZip 11+) to list of recognized compression types. [Christian Spieler]
- win32/nt.c: prevent calling IsValidAcl() with a NULL Acl pointer, to fix
false 'EA security check' failures. [Will Menninger]
- renamed proginfo/extra.fld into proginfo/extrafld.txt, to synchronize with
Zip3. [Chr. Spieler]
- process.c: added second try to find the EOCD64 record, to compensate for
(SFX-stub) bytes prepended to the archive without adjustment of the offset
records in the Zip file structures. [Will Menninger, Ed Gordon]
- fileio.c, process.c: replaced spurious use of Z_OFF_T by zoff_t.
[Chr. Spieler]
- win32/win32.c - utime2VFatFileTime(): initialize the wMillisecond field of
the SYSTEMTIME structure to 0 to ensure deterministic time conversion.
[N.N.]
- explode.c: corrected type for data stream size variables from zoff_t into
unzip-6.0/History.600 view on Meta::CPAN
allocation size for the slnk_entry structure by 2 for the two '\0'
end-of-string markers. [Chr. Spieler]
- unix/Makefile: modified bzip2 lib target to be only applicable to the
bzip2 subdir of the UnZip distribution. [Chr. Spieler]
- unix/configure: extended bzip2 support check from Zip's configure to better
support "externally" supplied bzip2 libraries. [St. Schweda, Chr. Spieler]
- vms/descrip_src.mms, bzip2/descrbz2.mms: cleaned up VMS MMS support for
integrated build of bzip2-enabled UnZip executables. [Chr. Spieler]
- msdos, unix, vms, win32: at request from SMS, changed all occurrences of
"DIR_BZ2LIB" symbol in build scripts for the directory of the bzip2 library
sources (and often also binaries) into "IZ_BZIP2", for synchronization
with Zip. [Chr. Spieler]
6.00d (17 Feb 08):
- win32/Makefile: fixed configuration variations of bzip2 support when using
non-standard build options regarding rtl linking; added documentation
section for the supported build variant flags on the nmake command line.
[Chr. Spieler]
6.00e01 (17 Feb 08):
- unzpriv.h: re-added "fixed" allocation of space for the first of two string
unzip-6.0/History.600 view on Meta::CPAN
- unzip.c: renamed error message constant for clarity. [Chr. Spieler]
- unshrink.c: revision to fix long-standing decompression bug, added boundary
checks to detect invalid compressed data. [Santiago Vila, Chr. Spieler]
- extract.c: added error message handling for "invalid data" errors from
unshrink(). [Chr. Spieler]
- process.c, unzpriv.h: disabled compilation of unused UNICODE_SUPPORT helper
function. [Chr. Spieler]
- process.c, win32/win32.c: added special win32-only version of the
wide_to_local_string() helper function to work around "ANSI vs. OEM"
codepage problems with non-Microsoft C-runtime libraries. [Chr. Spieler]
- zipinfo.c - zipinfo(): corrected "back at end-of-cdir" check (synchronized
it with the corresponding list_files() code). [Chr. Spieler]
- fileio.c - do_string(): closed UNICODE_SUPPORT related memory leaks
(free allocated utf8 buffers when no longer used). [Chr. Spieler]
- vms/vms.c - set_direc_attribs(): do not restore any size info from the
(PK-style) extra field record attributes settings. The new directory
created during extraction may contain fewer (restored) entries than the
original source folder, so that the old non-matching size data would
result in corrupted interal directory structures. [Steven M. Schweda]
6.00e04 (27 Apr 08):
unzip-6.0/History.600 view on Meta::CPAN
- unix/unix.c: add more detailed error message using strerror() when a
file error occurs. [SMS]
- unix/zipgrep - add additional information to top. Clean up some lines and
add commments. Added code to handle backslashes in archive file names,
and shell-special characters in the pattern. Changed to use "sed" for all
escaping of shell-special characters. Tried to get the exit status to
follow the status of egrep in the complex (default) situation, using only
standard Bourne shell features, and to exit early if egrep returns
status 2 (error). [SMS]
- vms/unzip_cli.help - VMS help updates. [SMS]
- vms/unzip_def.rnh - synchronized option description with unzip_cli.help.
[Chr. Spieler]
- fileio.c: extend backup number range from 65535 to 99999 on 32-bit systems;
fixed limit detection on 16-bit systems. [Chr. Spieler]
- zipinfo.c: changed date layout of "short" (one-line) zipinfo modes to always
use ISO-style YMD order. [Chr. Spieler]
- unix/configure: added a simple compiler test to check for a working C
compiler setup. [Steven M. Schweda]
- cmsmvs/vmmvs.h: removed __EBCDIC preprocessor symbol definition (not used
anywhere in UnZip, breaks compilation on Z-OS). ["Lutz", Chr. Spieler]
- unix/makefile - moved -L link option earlier in unzip$E rule. [Lutz]
unzip-6.0/History.600 view on Meta::CPAN
- proginfo/ziplimits.txt: updated discussion of program implementation limits
to the state of "released" Zip 3.0 and UnZip 6.0. [EG, Chr. Spieler]
- README, Bugs, ToDo: updated and syncronized documentation for release
candidate. [Chr. Spieler]
- windll/structs.h: added structure version id field at the "top" of the
"DCL" options struct. [EG]
- windll/structs.h: added UZ_DCL_STRUCTVER preprocessor symbol, holding the
currently valid version id of the DCL structure definition. [Chr. Spieler]
- windll/windll.c - Wiz_SetOpts(): exit function if version id of passed in
"DCL" structure is not equal to the expected setting. [EG, Chr. Spieler]
- windll/unexampl.c: synchronized with recent WinDLL option structure
addition. [EG, Chr. Spieler]
- windll/vc?/exampl/c_dll_ex.[dsp|vcproj]: new Visual Studio project files
for building the WinDLL C usage example uzexampl.exe. [EG, Chr. Spieler]
- windll/vb/vbunzip.bas: changed DLL interface to use UZxxx_I32 variants of
callback functions that split 64-bit values into high and low part 32-bit
integers that can be handled by VB(A)5/6. Inside the VB code, low and
high parts are added up in Currency type variables. Converted \ to / in
duplicate file message. Fixed MsgBox flags concatenation. Added support
for new OverwriteAll checkbox. [EG]
- windll/vb/vbunzip.frm: added OverwriteAll checkbox, added resizing to
txtMsgOut output box. [EG]
- windll/vb/vbunzip.frm, windll/vb/vbunzip.bas: cleaned up and completed the
recent modifications, resynchronized with WinDLL interface with UnZip 6.0
master source, removed all modification incompatible with VB5, fixed the
UZDLLServ_I32() callback calling interface, used Double instead of
Currency as Int64 summation type to prevent potential numeric overflow
issues. [Chr. Spieler]
6.00f (11 Jan 09):
- INSTALL: added notes on the difference between "old" Macintosh OS and
current Apple Mac OS/X, which is supported as a BSD Unix port . [EG]
- unzip.c - help_extended(): added some documentation about funzip and
unzipsfx stub. [EG]
unzip-6.0/History.600 view on Meta::CPAN
- vms/vms.c: made the declaration of sys$setdfprot() always active when
the SETDFPROT symbol is defined. [Chr. Spieler]
- unix/unix.c: added strerror(errno) output to various "Cannot..." I/O error
messages (in checkdir(), close_outfile(), set_symlnk_attribs()).
[Steven M. Schweda, Chr. Spieler]
- fileio.c - open_outfile(): added strerror(errno) output to the error
messages "cannot rename ..." and "cannot delete ...". [Chr. Spieler]
- fileio.c - do_string(): corrected string length passed to win_fprintf()
(comment string may get shortened by CRLF->LF translation). [Chr. Spieler]
- beos/beos.c, beos/beocfg.h, aosvs/aosvs.c, win32/win32.c: extended various
"Cannot..." I/O error messages with strerror(errno) output, to synchronize
code with current state of the Unix port. [Chr. Spieler]
- unzip.c, unzpriv.h, unix/configure: added better check for UTF-8 codeset
using nl_langinfo() function, as suggested on the sourceforge.net forum;
added nl_langinfo() to the "function existence" checks in the configure
script. [Chr. Spieler]
- wince/intrface.cpp: added missing wide_to_local_string() function from
win32.c (is [currently] needed in process.c). [Chr. Spieler]
6.00g01 (18 Jan 09):
- extract.c, windll/structs.h, windll/windll.txt: added a bufsize parameter
unzip-6.0/proginfo/extrafld.txt view on Meta::CPAN
2. On a system that already uses UTF-8 as system charset, this field
shall not repeat the string pattern already stored in the Zip
entry's standard name field. Instead, a field of exactly 9 bytes
(70 75 05 00 01 and 4 bytes CRC) should be created.
In this form with 5 data bytes, the field serves as indicator
for the UTF-8 encoding of the standard Zip header's name field.
3. This field shall not be used whenever the calculated CRC-32 of
the entry's standard name field does not match the provided
CRC checksum value. A mismatch of the CRC check indicates that
the standard name field was changed by some non-"up"-aware
utility without synchronizing this UTF-8 name e.f. block.
-Info-ZIP Unicode Comment Extra Field:
====================================
Stores the UTF-8 version of the entry comment as stored in the
central directory header.

* a) The "generic" (console-mode oriented) API has been used on UNIX,
* for example. This API provides a "callable" interface similar to the
* interactive command line of the normal program executables.
* b) The OS/2-only API provides (additional) functions specially tailored
* for interfacing with the REXX shell.
* c) The Win32 DLL API with a pure binary interface which can be used to
* build GUI mode as well as Console mode applications.
*
* Whenever a change that breaks backward compatibility gets applied to
* any of the DLL/Library APIs, the corresponding compatibility level should
* be synchronized with the current UnZip version numbers.
