iter_modules (iter_importers) ->
|
||
|
|
calls iter_importer_modules for each importer in iter_importers
|
||
|
|
|
||
|
|
iter_importers (meta_path, get_importer) ->
|
||
|
|
returns every importer in sys.meta_path + map(get_importer, sys.path)
|
||
|
|
|
||
|
|
get_importer(path):
|
||
|
|
|
||
|
|
returns a filtered list of sys.path_hooks for importers that can
|
||
|
|
handle this path; if there is no match, returns ImpImporter(),
|
||
|
|
which supplies a module iterator (ImpImporter.iter_modules) that
|
||
|
|
relies on getmodulename.
|
||
|
|
|
||
|
|
* A path_hook is a function of (path -> Maybe importer)
|
||
|
|
|
||
|
|
iter_modules(path, get_importer, prefix) ->
|
||
|
|
calls iter_importer_modules for each importer returned by path.map(get_importer)
|
||
|
|
|
||
|
|
iter_importer_modules(importer) ->
|
||
|
|
returns list of (filename, ispkg) for each module understood by the importer
|
||
|
|
* The method called depends on the class of the importer
|
||
|
|
* The default is a generic call for "no specific importer"
|
||
|
|
* For FILES, iter_import_modules returns a list of files whose
|
||
|
|
extensions match those in imp.get_suffixes(), which is hard-
|
||
|
|
coded into the interpreter.
|
||
|
|
* MEANING: Unless your importer can handle heterogenous module
|
||
|
|
suffixes, SourceFiles.iter_importer_modules can only find
|
||
|
|
homogeonous modules.
|
||
|

|
This relationship issue holds for Python 2.6 as well.
|
||
|
|
|
||
|
|
Python 3.3
|
||
|
|
|
||
|
|
The same issue holds, although now most of the extensions have been
|
||
|
|
moved to importlib._bootstrap.
|
||
|
|
|
||
|
|
It is the relationship between
|
||
|
|
importlib.machinery.FileFinder
|
||
|
|
and
|
||
|
|
_iter_file_finder_modules
|
||
|
|
|
||
|
|
That's killing us.
