Issue #13959: Move module type constants to Lib/imp.py.

Issue #13959: Move module type constants to Lib/imp.py.

Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py.

Fri, 04 May 2012 15:20:40 -0400

Issue #13959: Re-implement imp.get_suffixes() in Lib/imp.py.

This introduces a new function, imp.extension_suffixes(), which is
currently undocumented. That is forthcoming once issue #14657 is
resolved and how to expose file suffixes is decided.

PEP 302 + zipimport:

Mon, 30 Dec 2002 22:08:05 +0000

PEP 302 + zipimport:
- new import hooks in import.c, exposed in the sys module
- new module called 'zipimport'
- various changes to allow bootstrapping from zip files

I hope I didn't break the Windows build (or anything else for that
matter), but then again, it's been sitting on sf long enough...

Regarding the latest discussions on python-dev: zipimport sets
pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as
/path/to/Archive.zip/subdir/ are supported again.

This should match the situation in the 1.6b1 tree.

Some rearrangements for the importdl.c restructuring.

This is part of a set of patches by Greg Stein.

Added declarations for Mac code resource modules (Jack Jansen).

Added declarations for Mac code resource modules (Jack Jansen).

First part of package support.

Fri, 05 Sep 1997 07:33:22 +0000

First part of package support.

This doesn't yet support "import a.b.c" or "from a.b.c import x", but
it does recognize directories. When importing a directory, it
initializes __path__ to a list containing the directory name, and
loads the __init__ module if found.

The (internal) find_module() and load_module() functions are
restructured so that they both also handle built-in and frozen modules
and Mac resources (and directories of course). The imp module's
find_module() and (new) load_module() also have this functionality.
Moreover, imp unconditionally defines constants for all module types,
and has two more new functions: find_module_in_package() and
find_module_in_directory().

There's also a new API function, PyImport_ImportModuleEx(), which
takes all four __import__ arguments (name, globals, locals, fromlist).
The last three may be NULL. This is currently the same as
PyImport_ImportModule() but in the future it will be able to do
relative dotted-path imports.

Other changes:

- bltinmodule.c: in __import__, call PyImport_ImportModuleEx().

- ceval.c: always pass the fromlist to __import__, even if it is a C
function, so PyImport_ImportModuleEx() is useful.

- getmtime.c: the function has a second argument, the FILE*, on which
it applies fstat(). According to Sjoerd this is much faster. The
first (pathname) argument is ignored, but remains for backward
compatibility (so the Mac version still works without changes).

By cleverly combining the new imp functionality, the full support for
dotted names in Python (mini.py, not checked in) is now about 7K,
lavishly commented (vs. 14K for ni plus 11K for ihooks, also lavishly
commented).

Good night!

Removed some variables that are used to exchange data between import.c and

Mon, 21 Jul 1997 14:54:36 +0000

Removed some variables that are used to exchange data between import.c and
importdl.c: the MAXSUFFIXSIZE macro is now defined in importdl.h, and
the modules dictionary is now passed using PyImport_GetModuleDict().

Also undefine USE_SHLIB for AIX -- in AIX 4.2 and up, dlfcn.h exists
but we don't want to use it.

One last rename glitch: import_modules -> _PyImport_Modules.

Lots of changes, most minor (fatal() instead of abort(), use of
err_fetch/err_restore and so on). But...
NOTE: import.c has been rewritten and all the DL stuff is now in the
new file importdl.c.
