Greetings, I see that "setup.py register" does not understand "extras_require" >setup.py register \Python25\lib\distutils\dist.py:263: UserWarning: Unknown distribution option: 'extras_require' warnings.warn(msg) Is there any other way to provide optional dependencies and give user an ability to know about them and make a choice? -- --anatoly t.

[issue62] pkg_resources.WorkingSet.add_entry inconsistency
by Arve Knudsen 25 Feb '09

25 Feb '09

New submission from Arve Knudsen <arve.knudsen(a)gmail.com>: According to WorkingSet's documentation, it should call find_distributions with False for the only-parameter. In reality, it passes True, however. The documented behaviour is what I was after, but maybe it could be parameterized also in this method? ---------- keyword: pkg_resources messages: 245 nosy: aknuds-1 priority: bug status: unread title: pkg_resources.WorkingSet.add_entry inconsistency _______________________________________________ Setuptools tracker <setuptools(a)bugs.python.org> <http://bugs.python.org/setuptools/issue62> _______________________________________________

PEP 376 for Distutils
by Tarek Ziadé 25 Feb '09

25 Feb '09

Hello, I have started a PEP for Distutils, I would like to work out for Pycon. http://svn.python.org/projects/peps/trunk/pep-0376.txt It proposes some changes on the egg-info format, and various other enhancements, It's an early draft and any help/feedback is welcome !

In other words, it's a performance optimization, and a pretty major one when you're building an Environment object to look for available package versions. Cuts down on a LOT of file opens in the case where you have a ton of .egg-info's in site-packages, like on a Linux system with Python 2.5. Now, it is supported to leave that information out, but that's really intended only for working with development packages/checkouts, where you don't have so many of them on sys.path at any one time that the extra open is a big deal. >In Distutils, there should be one egg-info per package.

Note that sys.path could have more than one version of the same package on it, in two different directories. (Granted, one would take precedence over the other, but that should still be explicit.) >PEP, because as far as I >can see, the namespace package boilerplate in setuptools is using >pkgutil.extend_path which >fixes __path__ variables on the fly. So I can't think of a case where >a static __init__.py file >will be shared, thus removed. When a distutils package does it. I'm not positive, but if 'pip' supports namespace packages without using .pth files, then it has to use a shared __init__ also. And in the long run, easy_install will do this too. So, the uninstallation code should simply not remove file(s) that are referenced by more than one manifest in the target directory -- a relatively simple, future-proof safeguard, that doesn't require any specific knowledge of "namespace packages" per se.

[issue61] bdist_egg command doesn't stop after byte-compile errors
by Miroslav Madecki 24 Feb '09

24 Feb '09

New submission from Miroslav Madecki <miro(a)a-bb.net>: I'm using setuptools 06c9 on CentOs 5.X i386/x86_64. When using bdist_egg command one would expect setuptools to stop once byte-compile encounters an error (e.g. python source file with syntax errors) and would also return exit value other than 0 indicating a failure. Unfortunately neither is the case so if you use setuptools within makefiles it won't stop make in the case of errors. I'm surprised that nobody else reported this issue. Example is attached below. -Miro [miro@t42 monty]$ python25 ipdrfc-setup.py bdist_egg ..... byte-compiling build/bdist.linux-i686/egg/abn/ipdrfc/cfg.py to cfg.pyc File "build/bdist.linux-i686/egg/abn/ipdrfc/cfg.py", line 184 defset_exporter(ipAddr, cfg, RexGroup=None, RexListenPort=None, LogLevel=None): ^ SyntaxError: invalid syntax byte-compiling build/bdist.linux-i686/egg/abn/ipdrfc/reader.py to reader.pyc byte-compiling build/bdist.linux-i686/egg/abn/ipdrfc/sshconsole.py to sshconsole.pyc byte-compiling build/bdist.linux-i686/egg/abn/ipdrfc/backup.py to backup.pyc creating build/bdist.linux-i686/egg/EGG-INFO copying src/abn_ipdrfc.egg-info/PKG-INFO -> build/bdist.linux-i686/egg/EGG-INFO copying src/abn_ipdrfc.egg-info/SOURCES.txt -> build/bdist.linux-i686/egg/EGG-INFO copying src/abn_ipdrfc.egg-info/dependency_links.txt -> build/bdist.linux-i686/egg/EGG-INFO copying src/abn_ipdrfc.egg-info/namespace_packages.txt -> build/bdist.linux-i686/egg/EGG-INFO copying src/abn_ipdrfc.egg-info/top_level.txt -> build/bdist.linux-i686/egg/EGG-INFO zip_safe flag not set; analyzing archive contents... creating 'dist/abn_ipdrfc-3.2.0-py2.5.egg' and adding 'build/bdist.linux-i686/egg' to it removing 'build/bdist.linux-i686/egg' (and everything under it) [miro@t42 monty]$ echo $? 0 ---------- messages: 243 nosy: miro priority: urgent status: unread title: bdist_egg command doesn't stop after byte-compile errors _______________________________________________ Setuptools tracker <setuptools(a)bugs.python.org> <http://bugs.python.org/setuptools/issue61> _______________________________________________

bdist_rpm new option
by Tarek Ziadé 23 Feb '09

23 Feb '09

Hello We have worked on a fix for bdist_rpm, to avoid the error that occurs under Fedora or RedHat when the optimize flag is not activated. http://bugs.python.org/issue1533164 I am about to introduce a new option for this command, called "force-optimize" (and activated by default) This new option makes the bdist_rpm command drive the install command with the "optimize" flag activated by default (this fixes the problem) The rationale to introduce a new option is to make sure people don't get confused between the optimize flag that is forced when building a rpm package, and the "regular" optimize option used by the install command. This will prevent undesired side-effects. For instance, writing a setup.cfg with "optimize" to build rpms, might interfer when someone tries to tries to install the same package under Jython, Any opinion ? Otherwise I'll commit it this way Regards Tarek -- Tarek Ziadé | Association AfPy | www.afpy.org Blog FR | http://programmation-python.org Blog EN | http://tarekziade.wordpress.com/

That is, I intentionally prevented Python 2.4+ distutils from calculating the data files during option finalization, because the data files can't be correctly known until *after* the manifest is built. I have no idea what to do about this -- on either setuptools or distutils. For setuptools, file list calculation is inherently circular - an existing manifest is always reused and pruned, in order to support situations where a revctrl-based file list is then used in a scenario without revision control. (That is, the MANIFEST included with a shipped sdist is used as a backup for identifying files that might originally have been found via a revctrl finder.)

A bug filed to the setuptools tracker would probably also be a good idea, so that I'm not the only person who can look at it or provide a fix... either for setuptools or the stdlib, as appropriate.
