pysqlite egg problem
by Robin Becker Nov. 5, 2005

Nov. 5, 2005

I'm trying to follow the Turbogears wiki20, but I came across a problem with pysqlite. First off I am a complete newbie to the easy_setup and egg stuff and also have zero knowledge of pysqlite, but assuming that the filename I chose didn't have to exist I found that TG's tg-admin sql create failed. I assumed I needed to get some sort of database set up first so tried this to learn about pyslite C:\Tmp\wiki20>python Python 2.4.2 (#67, Sep 28 2005, 12:41:11) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from pysqlite2 import dbapi2 as sqlite Traceback (most recent call last): File "<stdin>", line 1, in ?

setuptools: .egg-info/ and PKG-INFO
by Ian Bicking Nov. 4, 2005

Nov. 4, 2005

I'm trying to figure out how I should deal with the .egg-info directory, and PKG-INFO. Right now PKG-INFO is being generated from setup.py. So I don't want to put it in my source control repository, since it is derivative. But I'm maintaining by hand some other files in the .egg-info directory, usually custom package metadata that we consume internally, so I need those files (and .egg-info) in the repository, and hence in the checkout. However, without PKG-INFO lots of things break, as pkg_resources gives a ValueError during some operations (e.g.: ValueError: ("Missing 'Version:' header and/or PKG-INFO file", ProjectName [unknown version] (/usr/home/ianb/co/IscapeLib/tests/appsetup/output/Proj-05))) -- this happens anytime I iterate over entry points, including when setuptools iterates over entry points, which means lots of setup.py commands are broken. They are broken simply because the incomplete .egg-info directory is on the path, even though I don't need direct access to it. I can run setup.py egg_info (creating PKG-INFO) for some reason (that I have not yet determined), but not my own custom setup.py extensions. This includes stuff like "python setup.py egg_info my_custom_command", so I have to write PKG-INFO in a completely separate command. If the .egg-info directory doesn't exist then pkg_resources will be happy, because it won't try to read the package as an egg at all. But it does, and so it's just awkward. Frankly I'd be 100% okay putting PKG-INFO in source control if it was the authoritative source, and I don't particularly care to use setup.py for this data. But that's a cop-out, I should really figure this out as it is. So... what do I do here? Should pkg_resources really just ignore packages without a PKG-INFO file? At least during scan? If I have to live with running setup.py egg_info until 0.6a7, that's fine. BTW, here's the full traceback I get: Traceback (most recent call last): File "setup.py", line 18, in ? package_data={ File "/usr/local/lib/python2.4/distutils/core.py", line 135, in setup ok = dist.parse_command_line() File "/usr/home/ianb/co/setuptools/setuptools/dist.py", line 227, in parse_command_line result = _Distribution.parse_command_line(self) File "/usr/local/lib/python2.4/distutils/dist.py", line 432, in parse_command_line args = self._parse_command_opts(parser, args) File "/usr/home/ianb/co/setuptools/setuptools/dist.py", line 549, in _parse_command_opts nargs = _Distribution._parse_command_opts(self, parser, args) File "/usr/local/lib/python2.4/distutils/dist.py", line 490, in _parse_command_opts cmd_class = self.get_command_class(command) File "/usr/home/ianb/co/setuptools/setuptools/dist.py", line 353, in get_command_class ep.require(installer=self.fetch_build_egg) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 1637, in require working_set.resolve(self.dist.requires(self.extras),env,installer)) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 480, in resolve env = Environment(self.entries) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 558, in __init__ self.scan(search_path) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 588, in scan self.add(dist) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 610, in add if dist not in dists: File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 1760, in __cmp__ def __cmp__(self, other): return cmp(self.hashcmp, other) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 1760, in __cmp__ def __cmp__(self, other): return cmp(self.hashcmp, other) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 1755, in <lambda> lambda self: ( File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 1782, in parsed_version self._parsed_version = pv = parse_version(self.version) File "/usr/home/ianb/co/setuptools/pkg_resources.py", line 1797, in version raise ValueError( ValueError: ("Missing 'Version:' header and/or PKG-INFO file", ProjectName [unknown version] (/usr/home/ianb/co/IscapeLib/tests/appsetup/output/Proj-05)) -- Ian Bicking / ianb(a)colorstudy.com / http://blog.ianbicking.org

Hi folks, Over on the vpython-users mailing list I've been trying to get help with VPython's complicated autoconf-based setup, which turns out to be fairly broken for OS X. They realize that the current setup is too complex and are looking at other options. The following is an exerpt from the ongoing discussion: > On Wed, 2005-10-19 at 21:06 -0700, Dethe Elza wrote: > >> On 19-Oct-05, at 4:57 PM, Jonathan Brandmeyer wrote: >> >>> >>> Are you (or anyone else out there) familiar with Scons? >>> >> >> What is wrong with using distutils[1], the standard method for >> building Python extensions?

I'm willing to create a parallel setuptools-based builder just for OS X use, since the same compiler problem isn't an issue on OS X, but can I use distutils with C++ code? Thanks! --Dethe

find_package_data in setuptools
by Ian Bicking Nov. 3, 2005

Nov. 3, 2005

I haven't really used the find_package_data that I emails distutils-sig about before (http://svn.pythonpaste.org/Paste/trunk/paste/util/finddata.py; just haven't gotten around to it, really. But clearly something like that should go in setuptools. And it's harder to maintain separately because you can't import it from another package (though I suppose svn:externals would work). TurboGears has been using the function; has it been working well there? -- Ian Bicking / ianb(a)colorstudy.com / http://blog.ianbicking.org

Just include an #egg link in your PyPI long_description. Take a look at the setuptools setup.py and setuptools.txt (which is where setup.py reads the long description from). Alternately, you can just put the #egg link on the download page, since in your case the download page is linked from PyPI. EasyInstall scans the home page and download pages of a project for useful links when you request it. Note, by the way, that this means as long as you have links on your download page for all the dependency projects, they should be satisfied from there as well, without a need to explicitly reference the download page.

-O3 brings the compiler to it's knees
by Simon Burton Nov. 3, 2005

Nov. 3, 2005

Is there a way to disable -O3 builds ? I have a big (100k+ lines) extension module, and -O3 compile is, at best useless and terribly slow to build, and at worst gobbles up all memory and kills the compile. Simon. -- Simon Burton, B.Sc.

New setuptools in subversion
by Phillip J. Eby Nov. 3, 2005

Nov. 3, 2005

Since the Python CVS has been migrated to Subversion, it's now possible to get fresh setuptools checkouts using EasyInstall. That is, you can use: easy_install setuptools==dev to request the development version of setuptools from Subversion. The current in-development version is 0.6a8dev, which means it is an unreleased version of 0.6a8, and will be considered obsolete when the real 0.6a8 is released. Some new "features" of the dev version include: * Bug fixes for all the Subversion-related problems reported recently by John J. Lee * Fix for the version conflict problem reported today by Ian Bicking * Fix for the extension building problem w/Pyrex and Python 2.4 reported by Kevin Dangoor So if you've been experiencing any of the above issues, you might want to give it a try. I still have a long list of to-do's for the official 0.6a8 release, so it probably won't be out before the weekend. In any case, it's always helpful to get some third-party testing before making an official release. Thanks.

Okay, after a bunch of Googling for swig_sources, I think the issue is that Pyrex is installed, but not a version that's compatible with Python 2.4. See this patch: https://www.redhat.com/archives/fedora-cvs-commits/2005-September/msg01305.… It looks like the user needs to either uninstall the Pyrex RPM, or install the updated version that contains this patch. See also this URL, that suggests what version might be appropriate: http://people.ubuntulinux.org/~scott/patches/pyrex/pyrex_0.9.3-3ubuntu1.pat… So, basically Pyrex's distutils support is broken for Python 2.4 without the patch to swig_sources. :( Last, but not least, see also: http://bugzilla.ubuntu.com/show_bug.cgi?id=4852 which is probably a good canonical location to point people to. However, now that I know the source of the problem, I can add a monkeypatch to the next version of setuptools to would work around the issue, if detected.
