Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Core (C code) Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: andy-chu (andy-chu) Assigned to: Nobody/Anonymous (nobody) Summary: Add a -z interpreter flag to execute a zip file Initial Comment: The motivation for this is that distributing a zip file is a very light and easy way to distribute a python program with multiple packages/modules. I have done this on Linux, Mac and Windows and it works very nicely -- except that you need a few extra files to bootstrap it: set PYTHONPATH to the zip file and run the main function. With this small patch, you get rid of the need for extra files. At the bottom is a demo on Linux. On Windows, you can do a similar thing by making a file that is both a zip file and a batch file. The batch file will pass %~f0 (itself) to the -z flag of the Python interpreter. I ran this by Guido and he seemed to think it was a fine idea. At Google, we have numerous platform-specific hacks in a program called "autopar" to solve this problem. I have included the basic patch, but if you guys agree with this, I will add some tests and documentation. And I think it might be useful to include something in the Tools/ directory to do what update_zip.sh does below (add a __zipmain__ module and a shebang/batch file header to a zip file, to make it executable)? I think this may also help to fix a bug with eggs: http://peak.telecommunity.com/DevCenter/setuptools#eggsecutable-scripts IMPORTANT NOTE: Eggs with an "eggsecutable" header cannot be renamed, or invoked via symlinks. They must be invoked using their original filename, in order to ensure that, once running, pkg_resources will know what project and version is in use. The header script will check this and exit with an error if the .egg file has been renamed or is invoked via a symlink that changes its base name. andychu testdata$ ls __zipmain__.py foo.py foo.pyc foo.zip foo_exe.zip header.txt update_zip.sh # The main program you're going to run in "development mode" andychu testdata$ ./foo.py foo bar argv: ['./foo.py', 'foo', 'bar'] # Same program, packaged into a zip file andychu testdata$ ./foo_exe.zip foo bar argv: ['-c', 'foo', 'bar'] # Contents of the zip file andychu testdata$ unzip -l foo_exe.zip Archive: foo_exe.zip warning [foo_exe.zip]: 51 extra bytes at beginning or within zipfile (attempting to process anyway) Length Date Time Name -------- ---- ---- ---- 243 06-18-07 20:01 __zipmain__.py 301 06-18-07 19:58 foo.py -------- ------- 544 2 files # Demo script to build an executable zip file. andychu testdata$ cat header.txt #!/usr/local/google/clients/python/trunk/python -z andychu testdata$ cat update_zip.sh #!/bin/bash # Make a regular zip file. zip foo.zip foo.py __zipmain__.py # Add a shebang line to it. cat header.txt foo.zip > foo_exe.zip # Make it executable. chmod 750 foo_exe.zip ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=305470&aid=1739468&group_id=5470 _______________________________________________ Patches mailing list Patches@python.org http://mail.python.org/mailman/listinfo/patches
