Sample setup.py for Numeric Python
by Greg Ward 29 Apr '18

29 Apr '18

Hi again -- [cc'd to Paul Dubois: you said you weren't following the distutils sig anymore, but this directly concerns NumPy and I'd like to get your input!] here's that sample setup.py for NumPy. See below for discussion (and questions!). ------------------------------------------------------------------------ #!/usr/bin/env python # Setup script example for building the Numeric extension to Python. # This does sucessfully compile all the .dlls. Nothing happens # with the .py files currently. # Move this file to the Numerical directory of the LLNL numpy # distribution and run as: # python numpysetup.py --verbose build_ext # # created 1999/08 Perry Stoll __rcsid__ = "$Id: numpysetup.py,v 1.1 1999/09/12 20:42:48 gward Exp $" from distutils.core import setup setup (name = "numerical", version = "0.01", description = "Numerical Extension to Python", url = "http://www.python.org/sigs/matrix-sig/", ext_modules = [ ( '_numpy', { 'sources' : [ 'Src/_numpymodule.c', 'Src/arrayobject.c', 'Src/ufuncobject.c' ], 'include_dirs' : ['./Include'], 'def_file' : 'Src/numpy.def' } ), ( 'multiarray', { 'sources' : ['Src/multiarraymodule.c'], 'include_dirs' : ['./Include'], 'def_file': 'Src/multiarray.def' } ), ( 'umath', { 'sources': ['Src/umathmodule.c'], 'include_dirs' : ['./Include'], 'def_file' : 'Src/umath.def' } ), ( 'fftpack', { 'sources': ['Src/fftpackmodule.c', 'Src/fftpack.c'], 'include_dirs' : ['./Include'], 'def_file' : 'Src/fftpack.def' } ), ( 'lapack_lite', { 'sources' : [ 'Src/lapack_litemodule.c', 'Src/dlapack_lite.c', 'Src/zlapack_lite.c', 'Src/blas_lite.c', 'Src/f2c_lite.c' ], 'include_dirs' : ['./Include'], 'def_file' : 'Src/lapack_lite.def' } ), ( 'ranlib', { 'sources': ['Src/ranlibmodule.c', 'Src/ranlib.c', 'Src/com.c', 'Src/linpack.c', ], 'include_dirs' : ['./Include'], 'def_file' : 'Src/ranlib.def' } ), ] ) ------------------------------------------------------------------------ First, what d'you think? Too clunky and verbose? Too much information for each extension? I kind of think so, but I'm not sure how to reduce it elegantly. Right now, the internal data structures needed to compile a module are pretty obviously exposed: is this a good thing? Or should there be some more compact form for setup.py that will be expanded later into the full glory we see above? I've already made one small step towards reducing the amount of cruft by factoring 'include_dirs' out and supplying it directly as a parameter to 'setup()'. (But that needs code not in the CVS archive yet, so I've left the sample setup.py the same for now.) The next thing I'd like to do is get that damn "def_file" out of there. To support it in MSVCCompiler, there's already an ugly hack that unnecessarily affects both the UnixCCompiler and CCompiler classes, and I want to get rid of that. (I refer to passing the 'build_info' dictionary into the compiler classes, if you're familiar with the code -- that dictionary is part of the Distutils extension-building system, and should not propagate into the more general compiler classes.) But I don't want to give these weird "def file" things standing on the order of source files, object files, libraries, etc., because they seem to me to be a bizarre artifact of one particular compiler, rather than something present in a wide range of C/C++ compilers. Based on the NumPy model, it seems like there's a not-too-kludgy way to handle this problem. Namely: if building extension "foo": if file "foo.def" found in same directory as "foo.c" add "/def:foo.def" to MSVC command line this will of course require some platform-specific code in the build_ext command class, but I figured that was coming eventually, so why put it off? ;-) To make this hack work with NumPy, one change would be necessary: rename Src/numpy.def to Src/_numpy.def to match Src/_numpy.c, which implements the _numpy module. Would this be too much to ask of NumPy? (Paul?) What about other module distributions that support MSVC++ and thus ship with "def" files? Could they be made to accomodate this scheme?

Can now compile simple extensions
by Greg Ward 29 Apr '18

29 Apr '18

Hi all -- at long last, I found the time to hack in the ability to compile extension modules to the Distutils. Mainly, this meant adding a 'build_ext' command which uses a CCompiler instance for all its dirty work. I also had to add a few methods to CCompiler (and, of course, UnixCCompiler) to make this work. And I added a new module, 'spawn', which takes care of running sub-programs more efficiently and robustly (no shell involved) than os.system. That's needed, obviously, so we can run the compiler! If you're in the mood for grubbing over raw source code, then get the latest from CVS or download a current snapshot. See http://www.python.org/sigs/distutils-sig/implementation.html for a link to the code snapshot. I'm still waiting for more subclasses of CCompiler to appear. At the very least, we're going to need MSVCCompiler to build extensions on Windows. Any takers? Also, someone who knows the Mac, and how to run compilers programmatically there, will have to figure out how to write a Mac-specific concrete CCompiler subclass. The spawn module also needs a bit of work to be portable. I suspect that _win32_spawn() (the intended analog to my _posix_spawn()) will be easy to implement, if it even needs to go in a separate function at all. It looks from the Python Library documentation for 1.5.2 that the os.spawnv() function is all we need, but it's a bit hard to figure out just what's needed. Windows wizards, please take a look at the 'spawn()' function and see if you can make it work on Windows. As for actually compiling extensions: well, if you can figure out the build_ext command, go ahead and give it a whirl. It's a bit cryptic right now, since there's no documentation and no example setup.py. (I have a working example at home, but it's not available online.) If you feel up to it, though, see if you can read the code and figure out what's going on. I'm just hoping *I'll* be able to figure out what's going on when I get back from the O'Reilly conference next week... ;-) Enjoy -- Greg -- Greg Ward - software developer gward(a)cnri.reston.va.us Corporation for National Research Initiatives 1895 Preston White Drive voice: +1-703-620-8990 Reston, Virginia, USA 20191-5434 fax: +1-703-620-0913

Two fixes (at last)
by Greg Ward 29 Apr '18

29 Apr '18

Hi all -- at long last, I have fixed two problems that a couple people noticed a while ago: * I folded in Amos Latteier's NT patches almost verbatim -- just changed an `os.path.sep == "/"' to `os.name == "posix"' and added some comments bitching about the inadequacy of the current library installation model (I think this is Python's fault, but for now Distutils is slavishly aping the situation in Python 1.5.x) * I fixed the problem whereby running "setup.py install" without doing anything else caused a crash (because 'build' hadn't yet been run). Now, the 'install' command automatically runs 'build' before doing anything; to make this bearable, I added a 'have_run' dictionary to the Distribution class to keep track of which commands have been run. So now not only are command classes singletons, but their 'run' method can only be invoked once -- both restrictions enforced by Distribution. The code is checked into CVS, or you can download a snapshot at http://www.python.org/sigs/distutils-sig/distutils-19990607.tar.gz Hope someone (Amos?) can try the new version under NT. Any takers for Mac OS? BTW, all parties involved in the Great "Where Do We Install Stuff?" Debate should take a good, hard look at the 'set_final_options()' method of the Install class in distutils/install.py; this is where all the policy decisions about where to install files are made. Currently it apes the Python 1.5 situation as closely as I could figure it out. Obviously, this is subject to change -- I just don't know to *what* it will change!

Package versioning
by Timothy Docker 29 Apr '18

29 Apr '18

Hi all, I've been aware that the distutils sig has been simmerring away, but until recently it has not been directly relevant to what I do. I like the look of the proposed api, but have one question. Will this support an installed system that has multiple versions of the same package installed simultaneously? If not, then this would seem to be a significant limitation, especially when dependencies between packages are considered. Assuming it does, then how will this be achieved? I am presently managing this with a messy arrangement of symlinks. A package is installed with its version number in it's name, and a separate directory is created for an application with links from the unversioned package name to the versioned one. Then I just set the pythonpath to this directory. A sample of what the directory looks like is shown below. I'm sure there is a better solution that this, and I'm not sure that this would work under windows anyway (does windows have symlinks?). So, has this SIG considered such versioning issues yet?

I've got one that pretty-much works. I'd be happy to get rid of the last couple peculiarities that I know of and massage it into a patch on CVS as long as someone assures me that there's a decent chance the patch will be accepted.

ANN: py2app 0.1.7
by Bob Ippolito 31 Dec '04

31 Dec '04

This announcement is available in HTML at: http://bob.pythonmac.org/archives/2004/12/30/ann-py2app-017/ `py2app`_ is the bundlebuilder replacement we've all been waiting for. It is implemented as a distutils command, similar to `py2exe`_, that builds Mac OS X applications from Python scripts, extensions, and related data files. It tries very hard to include all dependencies it can find so that your application can be distributed standalone, as Mac OS X applications should be. `py2app`_ 0.1.7 is included in the installer for `PyObjC`_ 1.2. If you have installed `PyObjC`_ 1.2, then you already have `py2app`_ 0.1.7 installed. Download and related links are here: http://undefined.org/python/#py2app `py2app`_ 0.1.7 is a bug fix release: * The ``bdist_mpkg`` script will now set up sys.path properly, for setup scripts that require local imports. * ``bdist_mpkg`` will now correctly accept ``ReadMe``, ``License``, ``Welcome``, and ``background`` files by parameter. * ``bdist_mpkg`` can now display a custom background again (0.1.6 broke this). * ``bdist_mpkg`` now accepts a ``build-base=`` argument, to put build files in an alternate location. * ``py2app`` will now accept main scripts with a ``.pyw`` extension. * ``py2app``'s not_stdlib_filter will now ignore a ``site-python`` directory as well as ``site-packages``. * ``py2app``'s plugin bundle template no longer displays GUI dialogs by default, but still links to ``AppKit``. * ``py2app`` now ensures that the directory of the main script is now added to ``sys.path`` when scanning modules. * The ``py2app`` build command has been refactored such that it would be easier to change its behavior by subclassing. * ``py2app`` alias bundles can now cope with editors that do atomic saves (write new file, swap names with existing file). * ``macholib`` now has minimal support for fat binaries. It still assumes big endian and will not make any changes to a little endian header. * Add a warning message when using the ``install`` command rather than installing from a package. * New ``simple/structured`` example that shows how you could package an application that is organized into several folders. * New ``PyObjC/pbplugin`` Xcode Plug-In example. Since I have been slacking and the last announcement was for 0.1.4, here are the changes for the soft-launched releases 0.1.5 and 0.1.6: `py2app`_ 0.1.6 was a major feature enhancements release: * ``py2applet`` and ``bdist_mpkg`` scripts have been moved to Python modules so that the functionality can be shared with the tools. * Generic graph-related functionality from ``py2app`` was moved to ``altgraph.ObjectGraph`` and ``altgraph.GraphUtil``. * ``bdist_mpkg`` now outputs more specific plist requirements (for future compatibility). * ``py2app`` can now create plugin bundles (MH_BUNDLE) as well as executables. * New recipe for supporting extensions built with `sip`_, such as `PyQt`_. Note that due to the way that `sip`_ works, when one sip-based extension is used, *all* sip-based extensions are included in your application. In practice, this means anything provided by `Riverbank`_, I don't think anyone else uses `sip`_ (publicly). * New recipe for `PyOpenGL`_. This is very naive and simply includes the whole thing, rather than trying to monkeypatch their brain-dead version acquisition routine in ``__init__``. * Bootstrap now sets ``ARGVZERO`` and ``EXECUTABLEPATH`` environment variables, corresponding to the ``argv[0]`` and the ``_NSGetExecutablePath(...)`` that the bundle saw. This is only really useful if you need to relaunch your own application. * More correct ``dyld`` search behavior. * Refactored ``macholib`` to use ``altgraph``, can now generate `GraphViz`_ graphs and more complex analysis of dependencies can be done. * ``macholib`` was refactored to be easier to maintain, and the structure handling has been optimized a bit. * The few tests that there are were refactored in `py.test`_ style. * New `PyQt`_ example. * New `PyOpenGL`_ example. `py2app`_ 0.1.5 was a major feature enhancements release: * Added a ``bdist_mpkg`` distutils extension, for creating Installer an metapackage from any distutils script. - Includes PackageInstaller tool - bdist_mpkg script - setup.py enhancements to support bdist_mpkg functionality * Added a ``PackageInstaller`` tool, a droplet that performs the same function as the ``bdist_mpkg`` script. * Create a custom ``bdist_mpkg`` subclass for `py2app`_'s setup script. * Source package now includes `PJE`_'s `setuptools`_ extension to distutils. * Added lots of metadata to the setup script. * ``py2app.modulegraph`` is now a top-level package, ``modulegraph``. * ``py2app.find_modules`` is now ``modulegraph.find_modules``. * Should now correctly handle paths (and application names) with unicode characters in them. * New ``--strip`` option for ``py2app`` build command, strips all Mach-O files in output application bundle. * New ``--bdist-base=`` option for ``py2app`` build command, allows an alternate build directory to be specified. * New `docutils`_ recipe. * Support for non-framework Python, such as the one provided by `DarwinPorts`_. .. _`py.test`: http://codespeak.net/py/current/doc/test.html .. _`GraphViz`: http://www.pixelglow.com/graphviz/ .. _`PyOpenGL`: http://pyopengl.sf.net/ .. _`Riverbank`: http://www.riverbankcomputing.co.uk/ .. _`sip`: http://www.riverbankcomputing.co.uk/sip/index.php .. _`PyQt`: http://www.riverbankcomputing.co.uk/pyqt/index.php .. _`DarwinPorts`: http://darwinports.opendarwin.org/ .. _`docutils`: http://docutils.sf.net/ .. _`setuptools`: http://cvs.eby-sarna.com/PEAK/setuptools/ .. _`PJE`: http://dirtSimple.org/ .. _`py2app`: http://undefined.org/python/#py2app .. _`py2exe`: http://starship.python.net/crew/theller/py2exe/ .. _`PyObjC`: http://pyobjc.sf.net/

How to define a platform?
by Phillip J. Eby 21 Dec '04

21 Dec '04

One of the trickier things about defining our "plugin" format is the definition of a platform. That is, how can we tell from metadata whether a given plugin is executable on the current platform? If we use 'distutils.util.get_platform()' and do simple string comparison, I believe this will result in both false positives and false negatives, due to e.g. the absence of processor info for Windows platforms, and the presence of processor info or OS version info for other platforms. For example, a 'linux-i386' module might work with a 'linux-i686' platform, yet not be accepted by a simple string comparison. Of course, if that metadata is encoded only in the plugin filename, then it's relatively simple to create copies with different filenames, one per applicable platform string. Or, perhaps there could be some type of configuration file that simply lists what platform strings (besides the one the machine itself generates) are acceptable on the machine. But, false positives seem harder to fix. For example, "win32" is used for both 32-bit and 64-bit Windows targets. I'm unsure whether any of the other targets have similar issues. Does anybody have any ideas?
