Nick Coghlan d5cacbb1d9 PEP 489: Multi-phase extension module initialization
Known limitations of the current implementation:

- documentation changes are incomplete
- there's a reference leak I haven't tracked down yet

The leak is most visible by running:

  ./python -m test -R3:3 test_importlib

However, you can also see it by running:

  ./python -X showrefcount

Importing the array or _testmultiphase modules, and
then deleting them from both sys.modules and the local
namespace shows significant increases in the total
number of active references each cycle. By contrast,
with _testcapi (which continues to use single-phase
initialisation) the global refcounts stabilise after
a couple of cycles.

Victor Stinner e134a7fe36 Issue #23752: _Py_fstat() is now responsible to raise the Python exception
Add _Py_fstat_noraise() function when a Python exception is not welcome.

Steve Dower f2f373f593 Issue #23152: Implement _Py_fstat() to support files larger than 2 GB on Windows.
fstat() may fail with EOVERFLOW on files larger than 2 GB because the file size type is an signed 32-bit integer.

Brett Cannon 2657df4744 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.

Brett Cannon f0434e647a Issue #14599: Generalize a test for ImportError.path and add support
in Python/dynload_shlibs.c.

This should fix the remaining importlib test failure on Windows.
Support in AIX and HP-UX will be in a separate checkin.

Brett Cannon fd0741555b Issue #2377: Make importlib the implementation of __import__().
importlib._bootstrap is now frozen into Python/importlib.h and stored
as _frozen_importlib in sys.modules. Py_Initialize() loads the frozen
code along with sys and imp and then uses _frozen_importlib._install()
to set builtins.__import__() w/ _frozen_importlib.__import__().

Guido van Rossum fef124346e Oops, one more part of the cygwin patch (SF patch #102409 by jlt63:
Cygwin Python DLL and Shared Extension Patch).  Add module.dll as a
valid extension.

jlt63 writes: Note that his change essentially backs out the fix for
bug #115973. Should ".pyd" be retained instead for posterity?
2001-01-10 21:17:27 +00:00
Guido van Rossum c8fcdcba36 Patch 102114, Bug 11725. On OpenBSD (but apparently not on the other
BSDs) you need a leading underscore in the dlsym() lookup name.

Guido van Rossum 96a8fb7e99 Cleanup patches from Greg Stein:
* in import.c, #ifdef out references to dynamic loading based on
  HAVE_DYNAMIC_LOADING

* clean out the platform-specific crud from importdl.c.
  [ maybe fold this function into import.c and drop the importdl.c file? Greg.]

* change GetDynLoadFunc's "funcname" parameter to "shortname". change
  "name" to "fqname" for clarification.

* each GetDynLoadFunc now creates its own funcname value.

  WARNING: as I mentioned previously, we may run into an issue with a
  missing "_" on some platforms. Testing will show this pretty quickly,
  however.

* move pathname munging into dynload_shlib.c
1999-12-22 14:09:35 +00:00
Guido van Rossum 22a1d3671b The old platform-specific contents of importdl.c, broken down into one
file per platform (really: per style of Dl API; e.g. all platforms
using dlopen() are grouped together in dynload_shlib.c.).

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