= Something great = Within samples/extending, Thomas Heller gives a Py2Exe setup.py script which automagically calls [[http://www.jrsoftware.org/isinfo.php|InnoSetup]] to create a great looking (and perfectly working) Windows-Installer. Yes, really, ONE setup.exe is created which contains ALL stuff to have a readily installable Software out of your product. = also large = I program using wxPython. A great library, a large library. {{{ 2.240.512 wxc.pyd 3.416.064 wxmsw24uh.dll }}} Two modules you cannnot skip. In addition there is as allways {{{ 974.915 python23.dll }}} giving more than 6 Megabytes with no line of code written In total: {{{ 28 Datei(en) 9.549.525 Bytes (in lib) }}} and {{{ 2 Datei(en) 1.011.779 Bytes (in prog) }}} summing up to 10.5 Megabyte ... not much with DSL, but... shocking, isn't it? = get it smaller = In the standard configuration [[http://www.jrsoftware.org/isinfo.php|InnoSetup]] compressed it down to around 6.5 Megabyte. I changed the setup.py to contain {{{ #!python print >> ofi, r"[Setup]" print >> ofi, r"AppName=%s" % self.name print >> ofi, r"AppVerName=%s %s" % (self.name, self.version) print >> ofi, r"DefaultDirName={pf}\%s" % self.name print >> ofi, r"DefaultGroupName=%s" % self.name print >> ofi, r"Compression=bzip" print >> ofi }}} ... the special line is {{{ #!python print >> ofi, r"Compression=bzip" }}} = the result = {{{ 4.335.283 setup.exe }}} Quite an OK download ... and I use ZODB and Elementtree and pythoncom and and and.... = Remarks = * I ([[http://videocapture.sourceforge.net/|MGr]]) get for my application (which uses wxWindows) even smaller files when using 7-zip instead of bzip. To use 7-zip one has to specify "Compression=none" in the generated installer script (*.iss) and then manually load the script into [[http://www.istool.org/|ISTool]], which is a front end to Inno Setup. Clicking at the 'Options' button and selecting '7-zip' in the compression combo box does the trick.{{{ 7.208 kB uncompressed 2.886 kB zip 2.677 kB bzip 2.160 kB 7-zip }}}The previous comparison shows, that 7-zip results by far in the smallest installer size. An additional benefit of using 7-zip is the fast installation. When using bzip, the files are decompressed in the last step of the installation process, right then when the files are written to the program folder. Since bzip is computationally quite intensive, the progress bar fills not extremely fast. When using 7-zip, there is a short decompression when starting the installer, but the installation process afterwards it fast as lightning, because of "Compression=none" :) . Addition: Innosetup 4.2 has 7z "LZMA" compression included. Just use {{{ #!python print >> ofi, r"Compression=lzma/max" }}} HAM2005-05-20 = 7ZIP and UPX = Repacking the "library.zip" with [[http://www.7-zip.org/|7-ZIP]] saving 357KB (577KB original to 220KB 7ZIP compressed). Note: it requires "import zlib" in your source file to allow unzipping operations. Using [[http://upx.sourceforge.net/|UPX ]] the executable packer to compress *.pyd, *.dll and *.exe Files: Example: _sre.pyd, _winreg.pyd, python23.dll, unicodedata.pyd, w9xpopen.exe, zlib.pyd 1516,2KB original to 584KB compressed) Everything together: Original Size: 2093,2 compressed: 804KB !!! A short Windows Batch-File to automate (see WinBatch): {{{ 7z.exe -aoa x library.zip -olibrary\ del library.zip cd library\ 7z.exe a -tzip -mx9 ..\library.zip -r cd.. rd library /s /q upx.exe --best *.* }}} = Automatically UPXing extension modules/dlls = While converting over from prior use of the Installer package, I missed its ability to automatically UPX binary modules as they were included in the distribution. So this example creates a custom command class based on py2exe that performs the UPX as part of the file copy process into the distribution directory. The one difference compared to Installer is that it doesn't currently keep a cache of UPXed files, although it could easily enough be extended to do that. Note that as designed I believe it will UPX any dll/pyd file copied over, even if they are part of the data files for the application. But since anything packaged up with py2exe is going to be running independently and unlikely to need to share any DLLs with other applications, there's little harm in UPXing anything in sight. The class below is a portion of a py2exe-subclass command class that I use that does the following, based on a new "upx" configuration value: * Compress (using upx) any dll or pyd file that is copied into the distribution directory. Since it does this at copy time, you only take the hit of upx whenever the file is updated (or you clean out the dist directory). * Deals with the fact that you have to postpone UPXing the main python##.dll file until py2exe has a chance to fix it's version identification, and that you shouldn't re-patch the file once it's been UPXed. This command class was written with py2exe 0.5.4. {{{ from distutils.core import setup from py2exe.build_exe import py2exe #-------------------------------------------------------------------------- # # Define our own command class based on py2exe so we can perform some # customizations, and in particular support UPXing the binary files. # #-------------------------------------------------------------------------- class Py2exe(py2exe): def initialize_options(self): # Add a new "upx" option for compression with upx py2exe.initialize_options(self) self.upx = 0 def copy_file(self, *args, **kwargs): # Override to UPX copied binaries. (fname, copied) = result = py2exe.copy_file(self, *args, **kwargs) basename = os.path.basename(fname) if (copied and self.upx and (basename[:6]+basename[-4:]).lower() != 'python.dll' and fname[-4:].lower() in ('.pyd', '.dll')): os.system('upx --best "%s"' % os.path.normpath(fname)) return result def patch_python_dll_winver(self, dll_name, new_winver=None): # Override this to first check if the file is upx'd and skip if so if not self.dry_run: if not os.system('upx -qt "%s" >nul' % dll_name): if self.verbose: print "Skipping setting sys.winver for '%s' (UPX'd)" % \ dll_name else: py2exe.patch_python_dll_winver(self, dll_name, new_winver) # We UPX this one file here rather than in copy_file so # the version adjustment can be successful if self.upx: os.system('upx --best "%s"' % os.path.normpath(dll_name)) }}} This class would then be used in your main setup() call as: {{{ setup(... cmdclass = {'py2exe': Py2exe} ... ) }}} For a simple project of mine that is built as a Windows service, this made the binaries in the installation take about a third of the size they would otherwise have needed, which was about half the size of the overall project. When built with UPX it was just under a MB, with the UPXing saving me about a MB on the binaries: {{{ File size Ratio Format Name -------------------- ------ ----------- ----------- 979005 -> 370176 37.81% win32/pe python23.dll 49212 -> 16896 34.33% win32/pe support/_socket.pyd 57401 -> 18432 32.11% win32/pe support/_sre.pyd 36864 -> 11264 30.55% win32/pe support/_winreg.pyd 45117 -> 17408 38.58% win32/pe support/datetime.pyd 24576 -> 6144 25.00% win32/pe support/perfmon.pyd 20539 -> 5120 24.92% win32/pe support/select.pyd 36864 -> 10752 29.16% win32/pe support/servicemanager.pyd 69632 -> 21504 30.88% win32/pe support/win32api.pyd 24576 -> 5632 22.91% win32/pe support/win32event.pyd 77824 -> 20992 26.97% win32/pe support/win32file.pyd 40960 -> 11776 28.75% win32/pe support/win32service.pyd 61497 -> 23552 38.29% win32/pe support/zlib.pyd 94208 -> 40448 42.93% win32/pe support/pywintypes23.dll -------------------- ------ ----------- ----------- 1618275 -> 580096 35.84% [ 14 files ] }}} For a much larger project (involving wxPython, Twisted, etc..), the binaries were again about a third of the size, but in this case ended up saving me over 7.5MB of space.
