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):

 - NO feature changes.

6.00c12 (15 Aug 05):

 - windll/csharp: new example project for .NET framework 1.1, written in C#.

    (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]

 - unzpriv.h, extract.c, unix/unix.c, atari/atari.c, atheos/atheos.c,

    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]

 - VMS: added support to extract "symlink" entries as symbolic links (requires

    up-to-date version of OpenVMS).  [Steven M. Schweda, Chr. Spieler]

 - unzip.1: added description of new VMS-specific "-S" option. [Chr. Spieler]

    VMS-specific options (-Y, -2).  [Chr. Spieler]

 - process.c: added preliminary (alpha-state) support for reading of Unicode

    Path extra field that now sets globals unipath_filename and

    unipath_escapedfilename (not yet functional).  [EG]

    source, modified vms/descrip.mms makefile.  [Steven M. Schweda]

 - UNIX: added new "-^" command line option that switches off the control

    character filter for extracted filenames.  [Chr. Spieler]

 - UNIX: added support for restoring attributes and UID/GID for symbolic

    links when appropiate OS support is provided.  [Chr. Spieler]

6.00d07 (26 Dec 07):

6.00c13 (02 Oct 05):

 - AOS/VS, Atari, AtheOS, BeOS, UNIX: fixed symlink code by avoiding fclose()

    on NULL handle in extract.c [Dan Yefimov]

 - AOS/VS, Atari, AtheOS, BeOS, UNIX (and unzpriv.h, fileio.c): modified the

    text-mode write function calls (in UzpMessagePrnt()) and binary write calls

    (everywhere else) [Chr. Spieler]

    when enabling BZIP2 support without LARGE_FILE support); added some

    (cosmetic) typecasts to shut up compiler warnings [Steven M. Schweda]

    added "find_bzip2_dir" helper script and bzlib.h include file wrapper

    [Steven M. Schweda]

6.00d01 (04 Mar 07):

 - extract.c: replaced local wsize variable (DLL only) by reference to the

    "global" variable G._wsize [Chr. Spieler]

 - unzpriv.h: use fputs() instead of fprintf() as output function in the

    FUNZIP variant of the Info() macro, to prevent misinterpreting format

 - fileio.c - is_vms_varlen_txt(): commented out the currently unused code for

    determining the VMS fileorg setting. [Steven M. Schweda]

 - extract.c - extract_or_test_files(): the "back at endsig" checking code

    is not used for the SFX stub. [Steven M. Schweda]

 - win32: changed all Win32-API calls with string parameters to explicitely use

    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]

 - crc32.c, crc32.h, crc_i386.S, crc_i386.asm, crc_i386.c: comprehensive

    [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

    [Steven M. Schweda]

 - bzip2/descrbz2.mms: added make Info-ZIP specific VMS make script, as a

    starting point for integrated bzip2 compilation support in a similar

    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

 - vms/vms.c, vms/UNZIP_MSG.MSG, vms/unzip_def.rnh, vms/unzip_cli.help: removed

    IZ_COMPERR support and documentation; debugging code should not be

    mentioned in end-user documentation.  [Chr. Spieler]

 - unzpriv.h: use __hpux instead of __HP_cc to determine support of "long long"

    type for HP (bundled ??) compiler.  [Steven M. Schweda]

    >>> This change may be wrong?? "long long" support is a compiler feature,

        not a runtime library feature!  [Chr. Spieler] <<<

 - VMS: added message file build to make procedures (missed change from

    6.00d06).  [Steven M. Schweda]

    library used by the bzip2 support in  UnZip.  [Chr. Spieler]

 - vms/descrip.mms, vms/descrip_src.mms: changed back so that the SMS-specific

    deviated bzip2 source package works again; added/completed support for

    standalone bzip2-included build using bzip2/descrbz2.mms.  [Chr. Spieler]

 - vms/make_unz.com, vms/link_unz.com: removed these obsolete files, they have

    been replaced by vms/build_unzip.com.  [Chr. Spieler]

    in "standalone" source setup, using bzip2/buildbz2.com for creating the

    bz2 object library.  [Chr. Spieler]

 - updated the UNICODE_SUPPORT code from Ed Gordon's work (6.00d05t, excluding

    the win32-wide specific code).  This code is unfinished, besides other

    issues there is a memory leak to be fixed.  [Ed Gordon, Chr. Spieler]

 - unzip.c: Added "static" to test_buf definition in the "NEXTBYTE operation

    test" code block of main function unzip().  [SMS]

 - windll/vb/vbunzip.bas: corrected UZDLLPAss callback function interface,

    adapted to recent DLL interface changes.  [Johnny Lee, Chr. Spieler]

 - windll: removed "DESCRIPTION" clause from all module definition files;

    newest VC++ version does no longer tolerate it.  [Chr. Spieler]

 - unzip.h: enable H_flag and U_flag for UNIX, VMS, WIN32 (those systems that

    are currently supposed to support UTF8 names); unzip.h must not depend on

    internal configuration settings like UNICODE_SUPPORT.  [Chr. Spieler]

6.00d11 (16 Feb 08):

 - vms/cmdline.c: canceled name-change for local variable 'restore_date'

    (was incomplete in 6.00d10 and broke compilation).  [Chr. Spieler]

    "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

    delimiters from the definition of type slinkentry, the "buf[]" structure

    member is not accepted by some older compilers. [Chr. Spieler]

 - aosvs, atari, atheos, beos, unix, vms - close_outfile(): Reduced the

    allocation size for the slnk_entry structure by 1, one of the two '\0'

    end-of-string markers is again part of the structure.  [Chr. Spieler]

 - unix/configure: export CC and IZ_BZIP2 symbols to flags, to feed their

    current settings to the child make process without having to use special

    make command qualifiers.  [Steven M. Schweda, Chr. Spieler]

    where directory name contains a '.' or '[' itself.  [Steven M. Schweda]

 - crc32.h: replaced explicit inclusion of zip.h by a note that this header

    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,

      -UU must be used now to entirely disable UTF-8 support.

    [Chr. Spieler]

 - windll/windll.{c|txt}: added U_flag to option stucture.  [Chr. Spieler]

 - man/unzip.1, man/zipinfo.1: added description of the new UTF-8 related

    syntax for the -U option.  [Chr. Spieler]

 - win32/w32cfg.h, wince/wcecfg.h: enabled UNICODE_SUPPORT by default.

    [Chr. Spieler]

 - win32/Makefile: adapted to modified UNICODE_SUPPORT default.  [Chr. Spieler]

 - wince/intrface.cpp - close_outfile(): moved local (wide string) copy of

    filename outside of conditional "set timestamps" block.  [Chr. Spieler]

 - unzpriv.h: do never include  here for the wince port (_WIN32_WCE or

    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]

 - VMS, unzip.c: help screen extended to show correct "-D" semantics for the

    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

    "normal" non-VMS-attributes case.  [Steven M. Schweda]

    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]

    calls, for better robustness and "in-code" documentation.  [Chr. Spieler]

 - extract.c - extract_or_test_entrylist(): fixed handling of \n in response

    to "overwrite (y/n/r)" prompt.  [Steven M. Schweda, Chr. Spieler]

 - extract.c, special version of "replace file" prompt for VMS to take into

    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 ,

    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]

 - vms/vms.c - set_direc_attribs(): ensure that the FAB block used is properly

    initialized.  [Steven M. Schweda]

 - aosvs, atari, atheos, beos, unix - mapname(): for all "unix-like" ports, the

    reserved file names "." and ".." are mapped to "_" resp. "__".

    [Steven M. Schweda, Chr. Spieler]

 - list.c - changed listing layout to emit four-digit years for file

    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]

 - man/unzipsfx.1 - Debian patches 4461_002 and 5293_009 fixing text errors;

    correct spelling of similarly and additional per debian patch; correct

     wrong formatting command \P to \fP.  [sanvila]

    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();

 - vms/cmdline.c, vms/unz_cli.cld: extended CLI to support the new extended

    meaning of the -o flag (-oo => "overwrite ALL existing" when retaining

    version numbers ("-V") and extracting archive members with attached version

    number (new /EXISTING option).  [Steven M. Schweda]

 - 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

    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]
