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):
 - 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]

6.00c13 (02 Oct 05), 6.00c14 (15 Nov 05), 6.00c15(17 Nov 05):
 - 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

    the egrep output is further piped through sed.  [Niklas Klein]
 - vms/vms.c: corrected case of the "__ia64" predefined preprocessor symbol.
    [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
    target functionality.  [Chr. Spieler]

    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.

    a production environment.  [Chr. Spieler]
 - 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]
 - vms/build_unzip.com: added support for compiling bzip2-enabled programs
    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]
 - unzpriv.h: Added <locale.h>-related stuff from 6.00d05t (SMS), with some
    corrections.  [Steven M. Schweda, Chr. Spieler]

    with VC++ 8.0 Express Edition.  [Chr. Spieler]
 - api.c: moved <setjmp.h> include down behind "unzip.h" include to shut up
    "depreciation" warnings with VC++ 8.0 and newer.  [Chr. Spieler]
 - windll/struct.h: added D_flag support to option structure.  [Chr. Spieler]
 - 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]

    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
    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]

6.00e02 (08 Mar 08):
 - unix/unix.c - close_outfile(): added missing semicolon in the SYMLINKS code
    for the non-SET_SYMLINK_ATTRIBS case.  [Steven M. Schweda]

    for space considerations; added credit note to README and referenced
    Myles Bennet in proginfo/CONTRIBS.  [Chr. Spieler]
 - vms/vms.c: fixed dir separator find logic in vms_path_fixdown() for cases
    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 <wchar.h> 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
    special VMS defaults.  [Steven M. Schweda]

    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):
 - vms/vms.c - set_direc_attribs(): fixed NAM[L] initialization for the
    "normal" non-VMS-attributes case.  [Steven M. Schweda]
 - vms/NOTES.TXT updated (version copied from zip30h05).  [Steven M. Schweda]

    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]
 - man/unzip.1: extended description of -U option to mention the #Lxxxxxx
    escape format for characters beyond the basic unicode page.  [Chr. Spieler]
 - proginfo/extrafld.txt: updated wording and line wrapping of Info-ZIP
    Unicode extra fields.  [Chr. Spieler]

6.00e05 (09 Sep 08):
 - unix/unix.c - version(): added OS info support for Mac OS X (including a
    note for the recognized CPU architecture).  [Steven M. Schweda]
 - unix/configure: check for Mac OS X special linker options is only executed
    on systems that have been identified as Mac OS X.  [Steven M. Schweda]
 - unix/Makefile: moved "solaris" targets into new "autoconfig generic" group
    of machine target aliases.  [Steven M. Schweda, 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 <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]
 - 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]

    "if" on it. [Steven M. Schweda]
 - 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]

    in "-V" mode (retaining version numbers); fixed some problems with exotic
    extended ODS5 file names, and files named ".".  [Steven M. Schweda]
 - 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
    UI extension to handle VMS-specific "overwrite or new version" settings.

    [Chr. Spieler]
 - vms/unzip_cli.help, vms/unzip_hlp.rnh: corrected a few typos and updated the
    help screen for the "unix-style" commands in the CLI help.  [Chr. Spieler]
 - vms/vms.c, extract.c, unzpriv.h: fixed the the error handling of the VMS-
    specific "newver/overwrite/skip" query by extending the return code range
    of open_output() for VMS, without any new global data.  [Chr. Spieler]

    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]

    "file exists ... skipping" message to get it displayed on one line.  [EG]
 - man/unzip.1, INSTALL: updated/corrected documentation for the UNIXBACKUP
    feature and the description of its -B qualifier.  [Chr. Spieler]

    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]

    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
