bdist_rpm fails - how to change what's included in hard linking?
by Andy Theuninck Aug. 16, 2008

Aug. 16, 2008

I'm trying to create an rpm package using bdist_rpm and it's failing. I can see exactly why it's failing, but I can't coax google into telling me how to fix it. First I see python create a tarball to put in the rpm's SOURCES: creating python-sybase-0.39 making hard links in python-sybase-0.39... hard linking Sybase.py -> python-sybase-0.39 hard linking blk.c -> python-sybase-0.39 hard linking cmd.c -> python-sybase-0.39 hard linking conn.c -> python-sybase-0.39 hard linking ctx.c -> python-sybase-0.39 hard linking databuf.c -> python-sybase-0.39 hard linking datafmt.c -> python-sybase-0.39 hard linking date.c -> python-sybase-0.39 hard linking datetime.c -> python-sybase-0.39 hard linking iodesc.c -> python-sybase-0.39 hard linking locale.c -> python-sybase-0.39 hard linking money.c -> python-sybase-0.39 hard linking msgs.c -> python-sybase-0.39 hard linking numeric.c -> python-sybase-0.39 hard linking setup.py -> python-sybase-0.39 hard linking sybasect.c -> python-sybase-0.39 tar -cf dist/python-sybase-0.39.tar python-sybase-0.39 gzip -f9 dist/python-sybase-0.39.tar removing 'python-sybase-0.39' (and everything under it) copying dist/python-sybase-0.39.tar.gz -> build/bdist.linux-i686/rpm/SOURCES One of the files required by setup.py (ez_setup.py) isn't getting hard linked. Thus, when rpmbuild unpacks the above tarball into the rpm BUILD directory and runs setup.py, it crashes with an ImportError. How do I adjust what files get hard linked into that tarball?

[issue33] zipped eggs cause various problems -- perhaps set default setting to unzipped?
by Zooko O'Whielacronx Aug. 15, 2008

Aug. 15, 2008

New submission from Zooko O'Whielacronx <zooko(a)zooko.com>: per http://mail.python.org/pipermail/python-dev/2008-April/078505.html installing an egg (with easy_install or ./setup.py install) in zipped form results in stack traces without source code lines attached. I hereby propose that zip_safe=False should be the default, unless the package producer and/or the package consumer specifically indicates that they prefer to zip the egg. I might be persuaded to change my mind about this if I saw some performance measurements which showed that zip_safe=False had a high cost. I'm skeptical that it has a high cost, since I've used it extensively for months (habitually specifying zip_safe=False in my setup.py files) and I haven't noticed any performance problem. PJE wrote, on the python-dev thread: "Are you using Python 2.5? As of 2.5, the linecache module should correctly read the source line from the present location of the source file the module was loaded from, regardless of the file name specified in the traceback." Yes, this was with Python 2.5.1. Note that the module was loaded from a .pyc file inside a zipped .egg (in the failing case), or from a .pyc file in an unzipped .egg (in the succeeding case). In the succeeding case, the name of the .py file, which is encoded inside the .pyc file, had been rewritten during the install process. Changed 4 months ago by zooko ¶ Here is another case that I encountered yesterday in which eggs being zipped caused a problem: we're using py2exe to build a Windows executable. (Also we are using py2app to build a Mac app.) py2exe can't find Python modules inside zipped eggs, although it can of course find them in unzipped eggs if the egg is added to the PYTHONPATH. At one point my programming partner Rob Kinninmont was using a script named ["hatch-eggs.py" http://allmydata.org/trac/tahoe/browser/misc/hatch-eggs.py?rev=1879]. That script no longer appears to be needed in our build system, but at this moment I can't figure out how we give py2exe access to the modules from the eggs that we installed... It is possible that we've customized the build machine by setting a distutils config file to say "always_unzip=True". I hope not, because that would mean our build will fail in mysterious ways when run on a different machine. Changed 4 months ago by zooko ¶ Oh, there it is: our [setup.cfg http://allmydata.org/trac/tahoe/browser/setup.cfg?rev=1938]. This means our Windows build will work on other machines, unless they have one of our dependencies already installed and that dependency is installed in zipped form. In that case, we'll get some strange error quite late in the process -- possibly something like the module not being found at run-time. So, this is another example of how unzipped eggs Just Work in more contexts (py2exe) than zipped ones do. Changed 4 months ago by nbecker ¶ zipped eggs also breaks pydoc: http://permalink.gmane.org/gmane.comp.python.devel/93788 Also, not very convenient if you need to view the source or debug. Changed 1 month ago by zooko ¶ Here's another one: http://mail.python.org/pipermail/distutils-sig/2008-July/009694.html Changed 1 month ago by zooko ¶ Here's another person who had trouble which he wouldn't have had if eggs were unzipped by default: http://mail.python.org/pipermail/distutils-sig/2007-December/008554.html Okay, here's the latest entry: my co-worker Greg Hazel, not knowing about the setup.cfg hack that I described earlier in this ticket, installed one of Tahoe's dependencies onto a build machine, using the default behavior of easy_install. Therefore, later there was a mysterious run-time error in the resulting package of Tahoe. Unfortunately I didn't catch this and explain it to Greg right away, so instead he spent some of his time figuring it out himself. After working-around the problem somehow, he reported to his manager: "fixed. you can say thank you to python eggs for screwing up py2exe's automatic dependency detection".

[buildout] improving zc.recipe.egg's README.txt
by Chris Withers Aug. 14, 2008

Aug. 14, 2008

Hi All, What I'd like to do at the start of the "Script generation" section was cat the setup.py of the demo egg to show the entry point where the demo eggs defines its script. However, given that the demo egg is a binary egg, I can't decide what the best way to do this is. I'd thought of using the zipfile module to reach inside the egg, but I'm confused as to why -py2.3.egg files are specified in the test and work even though I'm running with python 2.4 and there's no python 2.3 in sight? Any ideas welcome... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk

Setuptools: build_requires?
by Jeroen Ruigrok van der Werven Aug. 13, 2008

Aug. 13, 2008

So I am curious, why doesn't setuptools provide a build_requires directive similar to install_requires, but for python setup.py build? Right now a particular Python module will fail if you import said dependency somewhere in your code. Centralizing such a dependency in setup.py seems, to me, very logical. So what gives? -- Jeroen Ruigrok van der Werven <asmodai(-at-)in-nomine.org> / asmodai イェルーンラウフロックヴァンデルウェルヴェン http://www.in-nomine.org/ | http://www.rangaku.org/ | GPG: 2EAC625B Courage is not the absence of fear, but rather the judgment that something else is more important than fear.
