First draft of "sysconfig"
by Tarek Ziadé Jan. 1, 2010

Jan. 1, 2010

Hello, A while ago I've proposed to refactor the APIs that provides access to the installation paths and configuration variables at runtime into a single module called "sysconfig", and make it easier for all implementations to work with them. I've started a branch and worked on it, and I'd like to ask here for some feedback. And in particular from Jython and IronPython people because they would probably need to work in that file for their implementation and/or propose things to add. My understanding is that we have people like Phillip (Jenvey), Michael F., Frank W. in this list so they can comment directly and I don't need to cross-post this mail elsewhere. == Installation schemes == First, the module contains the installation schemes for each platform CPython uses. An install scheme is a mapping where the key is the "code" name for a directory, and the value the path of that directory, with some $variable that can be expanded. Install schemes are stored in a private mapping, where the keys are usually the value of os.name, and the value, the mapping I've mentionned earlier. So, for example, the paths for win32 are: _INSTALL_SCHEMES = { ... 'nt': { 'stdlib': '$base/Lib', 'platstdlib': '$base/Lib', 'purelib': '$base/Lib/site-packages', 'platlib': '$base/Lib/site-packages', 'include': '$base/include', 'platinclude': '$base/include', 'scripts': '$base/Scripts', 'data' : '$base', }, ... } where each key corresponds to a directory that contains some Python files: - stdlib : root of the standard library - platstdlib: root of platform-specific elements of the standard library - purelib: the site-packages directory for pure python modules - platlib: the site-packages directory for platform-specific modules - include: the include dir - platinclude: the include dir for platform-specific files - scripts: the directory where scripts are added - data: the directory where data file are added All these directory are read and used by: - distutils when a package is installed, so the install command can dispatch files in the right place - site.py, when Python is initialized IOW, any part of the stdlib can use these paths to locate and work with Python files. The public APIs are: * get_path_names() : returns a list of the path names ("stdlib", "platstdlib", etc.) * get_paths(scheme, vars) : Returns a mapping containing an install scheme. - "scheme" is the name of the scheme, if not provided will get the default scheme of the current platform - vars is an optonal mapping that can provide values for the various $variables. Notice that they all have default values, for example $base == sys.prefix. for example: get_paths('nt') * get_path(name, scheme, vars): Returns one path corresponding to the scheme. for example : get_paths('stdlib', 'nt') Those API are generic, but maybe we could add specific APIs like: * get_stdlib_path('nt') These API are basically a refactoring of what already exist in distutils/command/install.py == Configuration variables == distutils.sysconfig currently provides some APIs to read values from files like Makefile and pyconfig.h. These API have been placed in the global sysconfig module: * get_config_vars(): return a dictionary of all configuration variables relevant for the current platform. * get_config_var(name): Return the value of a single variable * get_platform(): Return a string that identifies the current platform. (this one is used by site.py for example) * get_python_version() : return the short python version (sys.version[:3]) -- this one could probably go away but is useful because that's the marker used by Python in some paths. == code, status, next steps == The code of the module can be viewed here, it's a revamp of distutils.sysconfig: http://svn.python.org/view/*checkout*/python/branches/tarek_sysconfig/Lib/s… I've refactored distutils/ and site.py so they work with this new module, and added deprecation warnings in distutils.sysconfig. All tests pass in the branch, but note that the code is still using the .h and Makefile files. This will probably be removed later in favor of a static _sysconfig.py file generated when Python is built, containing the variables sysconfig reads. I'll do this second step after I get some feedback on the proposal. Regards Tarek -- Tarek Ziadé | http://ziade.org
