UnZip, version 6.00, 20 April 2009
Features added (or removed):
6.00a ():
- Many changes by Myles
6.00b (12 Nov 04):
- Added dll changes from Mike White. [Mike White (MW), Ed Gordon (EG)]
- Added Unix Large File Support but must be enabled manually. [EG]
- Humble beginnings of adding configure script to Unix port to
autoconfigure large file support. [EG]
- VMS changes, including large file support, better handling of
-V and new -VV options, revised build procedures, and
documentation updates. [Steven Schweda (SMS)]
- file_size added to process.c to handle files sizes larger
than 2 GiB more cleanly when no large file support. [SMS]
- Large file debugging on Unix and VMS. [SMS, EG]
- Split w32i64.h with large file includes for dll [EG]
6.00c (1 Feb 05):
- Various Amiga and Win32 changes (see files). [Paul Kienitz (PK)]
- Add NOSHARE compile option for VMS. [SMS]
- Updates to windll (list.c, structs.h, uzexampl.c, uzexampl.h, windll.aps,
windll.c, windll.h, windll.rc, windll.txt, sfxwiz.c) to add VB support
for Zip64 to dll [MW]
6.00c (14 Feb 05):
- Added ODS5 extended file name support for VMS. (Eight-bit-only, no
Unicode.) Zip name character "?" is mapped to VMS name character
"/". ODS2 file names are now explicitly upper-case. [SMC]
- New VMS option, -2 (/ODS2), forces ODS2-compatible file names even
when the destination file system is ODS5. [SMC]
- New VMS option, -Y (/DOT_VERSION), causes archived file name endings
of ".nnn" (where "nnn" is a decimal number) to be treated as if they
were VMS version numbers (";nnn"). Example: "a.b.3" -> "a.b;3". [SMC]
6.00c8 (08 May 05):
- Added optional BZIP2 support, using the free BZIP2 library. Enabled
by defining the compile time option USE_BZIP2. [Johnny Lee]
- Revised optional ZLIB support to use the new zlib 1.2.x callback interface
when available (significant performance gain, now faster than UnZip's
built-in decompression code) [Christian Spieler]
- Added interface into zlib's unsupported "inflate9" callback code (a contri-
buted extension in zlib 1.2.x), for extracting Deflate64 entries. Enabled
by defining the compile time option HAVE_ZL_INFLAT64. [Christian Spieler]
- windll: added separate entry point Wiz_SingleEntryUnzipList for VB support,
changed Wiz_SingleEntryUnzip back to 5.x version [Christian Spieler]
6.00c9 (15 May 05):
- NO feature changes.
6.00c10 (21 May 05):
- WinCE port: Adapted PocketUnzip to UnZip6 code and enabled Zip64 support
for the WIN32 (non-WinCE) targets. [Chr. Spieler]
6.00c11 (23 May 05):

(currently unsupported by the Info-ZIP group) [Adrian Maull]
- MSDOS port: added warning message when used in an (32/64-bit) Windows
virtual MSDOS process; currently only shown when an error or warning
occured. [Johnny Lee, Chr. Spieler]

- NO feature changes.
6.00c (19 Nov 05):
- NO feature changes.
6.00d01 (04 Mar 07):
- unix/unix.c: when extracting directory entries, keep a SGID attribute
inherited from the parent dir (to allow content created in these new
directories to inherit the parent's GID), unless the directory entry was
created on UNIX, and UnZip was requested to restore UID/GID or SUID/SGID.
[Matthew Seitz, Chr. Spieler]
- process.c, modified info message handling for timestamping operation mode
to be more consistent with message handling of other operations: suppress
summary message only when qflag > 1 in process_zipfiles(); added time-stamp
success message to do_seekable() in non-quiet mode; moved message strings
to Far string constants. [Steven M. Schweda, Chr. Spieler]
- process.c - process_zipfiles(): suppress the "cannot find any wildcard
match ..." warning message for (qflag >= 3). [Chr. Spieler]
- vms/vms.c: added support for delayed restoration of directory attributes
[Steven M. Schweda]
- vms/vms.c - return_VMS(): implemented official HP-assigned facility code
in the calculation of UnZip's (non-success) VMS exit status codes.
[Steven M. Schweda]
- vms/vms.c, vms/cmdline.c vms/unz_cli.cld, unzip.c, unzip.h: added "-S"
option to change output record format into Stream-LF for text files when

beos/beos.c: added separate pInfo flag to record symlink entries, moved
symlink detection code into mapattr(), added VMS to the list of hosts known
to support symbolic links. [Steven M. Schweda, Christian Spieler]

up-to-date version of OpenVMS). [Steven M. Schweda, Chr. Spieler]
- unzip.1: added description of new VMS-specific "-S" option. [Chr. Spieler]
- unzip_cli.help, unzip_def.rnh: updated exit codes documentation, added new
option (-S resp. /TEXT=STMLF). [Steven M. Schweda, Chr. Spieler]

directory entry or for all files ("-DD"). [Chr. Spieler]
- windll: added support for new -D (-DD) option to dll interface, updated
the documentation. [Chr. Spieler]
6.00d08 (29 Dec 07):

OEM<-->ISO translation configurable at runtime. [Chr. Spieler]
- MSDOS (doscfg.h, msdos.c): OEM<-->ISO configured at runtime, depending on
system codepage (enabled for 437, 850, 858; disabled for 932, 936, 949,
950, 874, 1258; currently also disabled for all other OEM codepages because

the ANSI variant; this removes the dependency on the UNICODE and _UNICODE
compile flags being undefined. [NN, Chr. Spieler]
- zipinfo.c: on WIN32, archive filename display must be fed through codepage
translation. [Chr. Spieler]
- zipinfo.c - zipinfo(): repaired several memory leaks when the listing loop
is stopped prematurely because of inner errors. [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]

bzip2 decompression capability (mostly copied from msdos/Makefile.dj2,
is not yet tested). [Chr. Spieler]
- process.c: added additional consistency checks to find_ecrec64().
- extract.c, list.c, zipinfo.c: reviewed the "central dir processing complete"
check to take into account the new status semantics from find_ecrec64().
[Chr. Spieler]

should be read after zip.h resp. unzip.h. [Steven M. Schweda, C. Spieler]
- unix/configure, unix/Makefile: cleaned up auto-configured build procedure.
* pass the "configure"-selected C optimizations to the bzip2 build process.
* clean only affects the unzip-specific bzip2 subdirectory.
* let make display the bzip2 clean subprocess call.
[Steven M. Schweda]
- unzip.c, unzip.h, zipinfo.c, fileio.c - UNICODE_SUPPORT, revised the
options to control UTF-8 handling:
* removed the -H option
* modified -U option syntax: -U forces to escape all non-ASCII UTF-8 chars,

POCKET_UNZIP), this must be handled elsewhere for C++. [Chr. Spieler]
- unzip.c: removed the -U option description from the introductory screen for
WIN32 because of lacking space. Maybe, these "debugging" options should not
be shown there at all. [Chr. Spieler]
6.00e03 (29 Mar 08):
- unix/configure: corrected detection of ANSI C vs. bundled C compiler on
HP-UX. [Steven M. Schweda]

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):
- vms/vms.c - set_direc_attribs(): fixed NAM[L] initialization for the

wince/wcecfg.h : revised the UNICODE_SUPPORT code, added direct support for
UTF-8 being the native MBCS char encoding, allowed separate activation of
the "UTF-8 is native character coding" and the "translate UTF-8 <==> native
extended-ASCII via Unicoded wchar_t" support methods. [Chr. Spieler]
- unix/configure, unix/Makefile: extended configure script to support
automatic selection of UNICODE_SUPPORT support on capable systems,
completed configuration support for the linking step. [Chr. Spieler]
- unix/unxcfg.h: changed interdependency rules of LARGE_FILE_SUPPORT and
ZIP64_SUPPORT to prevent unsupported symbol combinations. [Chr. Spieler]

account that VMS normally created a new version instead of overwriting
an existing file. [Steven M. Schweda]
- unzpriv.h: for VMS, undefine the PATH_MAX definition provided by <limits.h>,
because it does not take into account long name support of ODS-5 volumes.
[Steven M. Schweda]
- VMS: added zlib.h and infback9.h jacket headers for support of using zlib
as inflate decompression code; revised build procedures for zlib support
(build_unzip.com, descrip.mms, descrip_src.mms). [Steven M. Schweda]
- inflate.c: corrected condition when to include "infback9.h" for Deflate64
support with zlib 1.2.x. [Chr. Spieler]
- extract.c: standardized wording of error messages in SET_DIR_ATTRIBS code.
[Steven M. Schweda]

date-time-stamps. [Ed Gordon, Chr. Spieler]
- process.c - find_ecrec(): fixed zipfile comment handling within the Zip64-
compatible end-of-central-dir records scanning, to take into account that
the file pointer is no longer at the zipfile end when the eocdrec scanning
has finished. [Chr. Spieler]
- process.c, zipinfo.c: revised and reorganized zipinfo log header output;
the zip archive comment has to be reported before all of the eocdir info
could be collected. [Chr. Spieler]

- vms/descrip_deps.mms: restored correct file which was accidentally
overwritten by vms/descrip_src.mms. [Steven M. Schweda]
- vms/build_unzip.com: optimized the distinction between "compile destination
subdir" for integrated BZIP2 compilation (should distinguish between the
different compilers supported for VAX) and "external library dir" for
user-supplied BZIP2 (and ZLIB) libraries (user-supplied library is expected
to work with any supported compiler on VAX, so no dependency on the
specific compiler used). [Steven M. Schweda]
- unzip.c: replaced tab characters in output messages by appropiate number of
spaces (assuming standard tab spacing of 8 chars), to prevent mis-formatted
output on terminals with non-standard tabstop settings. [S. M. Schweda]
- unix/unix.c
* set_symlnk_attribs(): fixed uid/gid size check before calling lchown();
* set_direc_attribs(): repared wrongly inserted patch and fixed uid/gid
size check before calling chown(). [Chr. Spieler]

- extract.c - extract_or_test_entrylist(): added code to skip the generic user
query "overwrite (y/n/r)?" when extracting an entry with attached version
number in "-V" (keep version number) mode. [Steven M. Schweda, C. Spieler]
- vms/unzip_cli.help, vms/unzip_hlp.rnh: updated documentation to reflect the
UI extension to handle VMS-specific "overwrite or new version" settings.
[Steven M. Schweda]

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]

latest Zip 3.1 beta, removed the "switch to UTF-8 codeset" code because
it proved to not work as expected. [Ed Gordon, Chr. Spieler]
- win32/w32cfg.h: use rtl-provided MBCS functions for MinGW32 when compiled
and linked against msvcrt.dll. [Chr. Spieler]
- extract.c - fnfilter(): added "enhanced" non-printable charcode filtering
when a locale-aware isprint() implementation is available (controlled by
the preprocessor symbol HAVE_WORKING_ISPRINT). [Chr. Spieler]
- win32: enabled "enhanced" fnfilter() filtering for compiler environments
using MSVC 6.0 (or newer) runtime, and for Borland C. [Chr. Spieler]

support of /NAMES=AS_IS with older DECC distributions. [Steven M. Schweda]
- vms/build_unzip.com, vms/descrip.mms, vms/descrip_src.mms: resolved a
/NAME=AS_IS case issue by changing the linking command for bzip2-enabled

loading the callback function. [Steven M. Schweda]
- vms/NOTES.TXT: cleaned up wording of the Symbolic Links section. [SMS]
- extract.c, fileio.c, process.c, unzpriv.h: fixed recognition of "native
UTF-8" general purpose flag bit 11 when processing local header, added

link attributes do never ever need 64-bit treatment. [Chr. Spieler]
- man/unzip.1, ToDo: added remark to DECRYPTION section on still missing
support for UTF-8 encoded passwords on systems like Windows, that are
Unicode-aware without using UTF-8 as native character encoding; added
ToDo note about fixing UTF-8 password handling in the next release.
