UPX - упаковщик исполняемых модулей
| Цитата | | Отличная программа для сжатия exe-файлов без потерь. После сжатия ужимаемая программа полностью работоспособна без установки какого-либо дополнительного ПО - а это значит что распаковывать ехе-шник не надо. Я провел опыт: взял 2 одинаковых exe-файла и один заархивировал WinRar'ом на максимальной степени сжатия, другой - UPX'ом. И что? Оба файла оказались одинакового размера - примерно в 3 раза меньше оригинала! При том, что rar-архив нужно распаковывать, а ужатый UPX'ом - нет. Однако, файл, сжатый UPX'ом требует больше ресурсов для работы, нежели несжатый. Алгоритм UPX используется, например, WinRar'ом для упаковки sfx-архивов. А исполняемый файл Total Commander'а также сжат UPX'ом. |
Самое главное: Сохраняет экспортируемые функции находящиеся в .EXE файле!

problem with certain binutils versions
Changes in 1.23 (05 Sep 2002)
* atari/tos: fixed an unpacking problem where a buffer was too
small (introduced in 1.22)
* linux/386: don't give up too early if a single block turns out
to be incompressible

Changes in 1.22 (27 Jun 2002)
* atari/tos: the stub now flushes the CPU cache to avoid
problems on 68030+ machines
* source code: additional compiler support for Borland C++,
Digital Mars C++ and Watcom C++
Changes in 1.21 (01 Jun 2002)
* New option `--crp-ms=' for slightly better compression at the cost
of higher memory requirements during compression.
Try `upx --best --crp-ms=100000'. See the docs for more info.
* source code: portability fixes
* source code: compile fixes for g++ 3.0 and g++ 3.1
Changes in 1.20 (23 May 2001)
* slightly faster compression
* work around a gcc problem in the latest djgpp2 distribution
* watcom/le: fixed detection of already compressed files
* win32/pe: do not compress RT_MANIFEST resource types
* win32/pe: improved the error message for empty resource sections
* [NOTE: the jump from 1.08 to 1.20 is to avoid confusion with
our unstable development releases 1.1x and 1.9x]
Changes in 1.08 (30 Apr 2001)
* INFO: http://upx.sourceforge.net now is the new permanent UPX home page

Changes in 1.07 (20 Feb 2001)
* win32/pe: corrected the TLS callback check
* win32/pe: really fixed that rare bug in relocation handling
* win32/pe: experimental support for SizeOfHeaders > 0x1000
* win32/pe: check for superfluous data between sections
* win32/pe: compressing screensavers (.scr) should finally work
Changes in 1.06 (27 Jan 2001)
* win32/pe: the check for TLS callbacks introduced in 1.05
was too strict - disabled for now
* dos/com: decreased the decompressor stack size a little bit
Changes in 1.05 (24 Jan 2001)
* win32/pe: refuse to compress programs with TLS callbacks
* win32/pe: stub changes to avoid slowdowns with some virus monitors
* win32/pe: reverted the relocation handling changes in 1.04
* linux/386: dont try to compress Linux kernel images (have a look
at the unstable UPX 1.1x beta versions for that)
Changes in 1.04 (19 Dec 2000)
* dos/exe: fixed an internal error when using `--no-reloc'
* win32/pe: fixed a rare bug in the relocation handling code
* some tunings for the default compression level
Changes in 1.03 (30 Nov 2000)
* linked with a new version of the NRV compression library:
- improved compression ratio a little bit
- overall significantly faster compression
- much faster when using high compression levels like `-9' or `--best'
- much faster with large files
* atari/tos: added support for FreeMiNT
* the 32-bit DOS version now uses the new CWSDSTUB extender
Changes in 1.02 (13 Sep 2000)
* watcom/le: fixed a problem with the Causeway extender
* win32/pe: don't automatically strip relocs if they seem needed

PE header was set incorrectly
Changes in 1.00 (26 Mar 2000)
* documentation updates
* watcom/le: do not duplicate the non-resident name table
* win32/pe: fixed an import handling problem: sometimes too much data
could be deleted from a file -> the uncompressed file would not work
anymore
