unzip ======================================================================== UnZip is an extraction utility for archives compressed in .zip format (also called 'zipfiles'). Although highly compatible both with PKWARE's PKZIP and PKUNZIP utilities for MS-DOS and with Info-ZIP's own Zip program, our primary objectives have been portability and other-than- MSDOS functionality. Runtime requirements (these, or newer): cygwin-1.7.0-51 Build requirements (these, or newer): cygwin-1.7.0-51 gcc-core-3.4.4-999 binutils-2.19.51-1 cygport-0.9.8.1 make-3.81-2 Canonical homepage: http://www.info-zip.org/ Canonical download: ftp://ftp.info-zip.org/pub/infozip/src/ License: Info-ZIP (Mostly BSD-ish) Language: C ======================================================================== Build instructions: unpack unzip-6.0-X-src.tar.bz2 if you use setup to install this src package, it will be unpacked under /usr/src automatically cd /usr/src cygport ./unzip-6.0-X.cygport all This will create: /usr/src/unzip-6.0-X.tar.bz2 /usr/src/unzip-6.0-X-src.tar.bz2 To find out the files included in the binary distribution, you can use "cygcheck -l unzip", or browse the listing for the appropriate version at . ======================================================================== Port Notes: ---------- unzip-6.0-10 -- 2009 Aug 04 ----------- * Update to latest release. Upstream changes: = UnZip 6.0 finally supports nowadays "large" files of sizes > 2 GiB! = This is the first release containing support for the PKWARE Zip64 enhancements. = Major changes are: - Support PKWARE ZIP64 extensions, allowing Zip archives and Zip archive entries larger than 4 GiBytes and more than 65536 entries within a single Zip archive. This support is currently only available for Unix, OpenVMS and Win32/Win64. - Support for bzip2 compression method. - Support for UTF-8 encoded entry names, both through PKWARE's "General Purpose Flags Bit 11" indicator and Info-ZIP's new "up" unicode path extra field. (Currently, on Windows the UTF-8 handling is limited to the character subset contained in the configured non-unicode "system code page".) - Fixed "Time of Creation/Time of Use" vulnerability when setting attributes of extracted files, for Unix and Unix-like ports. - Fixed memory leak when processing invalid deflated data. - Fixed long-standing bug in unshrink (partial_clear), added boundary checks against invalid compressed data. - On Unix, keep inherited SGID attribute bit for extracted directories unless restoration of owner/group id or SUID/SGID/Tacky attributes was requested. - On Unix, allow extracted filenames to contain embedded control characters when explicitly requested by specifying the new command line option "-^". - On Unix, support restoration of symbolic link attributes. - On Unix, support restoration of 32-bit UID/GID data using the new "ux" IZUNIX3 extra field introduced with Zip 3.0. - Support for ODS5 extended filename syntax on new OpenVMS systems. - Support symbolic links zipped up on VMS. - New -D option to suppress restoration of timestamps for extracted directory entries (on those ports that support setting of directory timestamps). By specifying "-DD", this new option also allows to suppress timestamp restoration for ALL extracted files on all UnZip ports which support restoration of timestamps. - On OS/2, Win32, and Unix, the (previously optional) feature UNIXBACKUP to allow saving backup copies of overwritten files on extraction is now enabled by default. * Bring in debian patches from (sid) 6.0-1 ---------- unzip-5.52-10 -- 2009 Mar 05 ----------- * Fork for cygwin-1.7 development ---------- unzip-5.52-3 -- 2009 Mar 05 ----------- * Bring in debian patch 5.52-12 - fixes CAN-2005-2475 - fixes CVE-2005-4667 - fixes CVE-2008-0888 * Enable -W and -B options (see man page) * Enable large file support. But, be warned, this is still quite limited in unzip-5.52. "Real" large file support is forthcoming in unzip-6.0 (currently in beta). ---------- unzip-5.52-2 -- 2006 Oct 14 ----------- * Identical to 5.52-1 below but converted to cygports. ---------- unzip-5.52-1 -- 2006 May 07 ----------- * routine update. Some of our cygwin-specific fixes have been incorporated, but not all. This version was released as a test version only, and never promoted to active. (cygports also released an unofficial version of this package, ALSO named "unzip-5.52-1". It included encryption support but NONE of the bugfixes the cygwin-official version had, which had not been absorbed by the infozip release) ----- version 5.50-5 ----- This is the cygwin-1.5.2 FLAG DAY release. ----- version 5.50-4 ----- This is the cygwin-1.5.1 FLAG DAY release. Moved doc files to /usr/share/* Fixed serious bug with lseek (Thanks, Dave Rothenberger) ----- version 5.50-3 ----- This is the cygwin-1.5.0 FLAG DAY release. ----- version 5.50-2 ----- Add fix for obscure directory traversal security problem. See unix/unix.c for more info. ----- version 5.50-1 ----- Update to version 5.50, and use new script-driven build scheme. ----- version 5.41-1 ----- Initial release. * built as a unix app. Also, it is -mno-win32 clean; using -mno-win32 or not makes no difference in the final .exe. * understands symlinks * The binary contains full decryption support. (Note that the cygwin zip binary, however, does NOT contain ENcryption support. Blame US crypto export laws).
