Martin v. Löwis ea62d2535f Bug #1421664: Set sys.stderr.encoding 2006-04-03 10:56:49 +00:00
Tim Peters 62e97f023b In format strings slinging Py_ssize_t, unconditionally
interpolate PY_FORMAT_SIZE_T instead of #if'ing on
MS_WIN64.

Tim Peters c9d78aa470 Years in the making.
objimpl.h, pymem.h:  Stop mapping PyMem_{Del, DEL} and PyMem_{Free, FREE}
to PyObject_{Free, FREE} in a release build.  They're aliases for the
system free() now.

_subprocess.c/sp_handle_dealloc():  Since the memory was originally
obtained via PyObject_NEW, it must be released via PyObject_FREE (or
_DEL).

pythonrun.c, tokenizer.c, parsermodule.c:  I lost count of the number of
PyObject vs PyMem mismatches in these -- it's like the specific
function called at each site was picked at random, sometimes even with
memory obtained via PyMem getting released via PyObject.  Changed most
to use PyObject uniformly, since the blobs allocated are predictably
small in most cases, and obmalloc is generally faster than system
mallocs then.

If extension modules in real life prove as sloppy as Python's front
end, we'll have to revert the objimpl.h + pymem.h part of this patch.
Note that no problems will show up in a debug build (all calls still go
thru obmalloc then). Problems will show up only in a release build, most
likely segfaults.

Guido van Rossum 9d7855076a Address an coverity issue. Coverity was complaining about a line that's fine,
but an earlier line checked for v != NULL unnecessarily.

Neal Norwitz 4281cef205 Use Py_ssize_t for _Py_RefTotal.
I tried to handle Win64 properly, but please review.

Neal Norwitz e92fba0a12 Get rid of run_err_mod(). It was only used in two places.
One place it wasn't necessary since mod was already checked.
Inline the check that mod != NULL for the other use.

Martin v. Löwis 056a69cba6 Reconst parameters that lost their const in the AST merge. 2006-03-01 16:55:42 +00:00
Brett Cannon bf36409e2a PEP 352 implementation. Creates a new base class, BaseException, which has an
added message attribute compared to the previous version of Exception.  It is
also a new-style class, making all exceptions now new-style.  KeyboardInterrupt
and SystemExit inherit from BaseException directly.  String exceptions now
raise DeprecationWarning.

Applies patch 1104669, and closes bugs 1012952 and 518846.

Neal Norwitz db83eb3170 Fix Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter.
Needs backport.

Neal Norwitz adb69fcdff Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines,
simplifies a lot of error handling code, and fixes many memory leaks.

Martin v. Löwis b45b315855 Patch #1350409: Port signal handling to VS 2005. 2005-11-28 17:34:23 +00:00
Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Neal Norwitz 40d3781416 - Fix segfault with invalid coding.
- SF Bug #772896, unknown encoding results in MemoryError, which is not helpful

I will only backport the segfault fix.  I'll let Anthony decide if he wants
the other changes backported.  I will do the backport if asked.

Martin v. Löwis d35edda682 Forward UnicodeDecodeError into SyntaxError for source encoding errors.
Will backport to 2.4.

Raymond Hettinger d794666048 * Improve code for the empty frozenset singleton:
- Handle both frozenset() and frozenset([]).
  - Do not use singleton for frozenset subclasses.
  - Finalize the singleton.
  - Add test cases.
* Factor-out set_update_internal() from set_update().  Simplifies the
  code for several internal callers.
* Factor constant expressions out of loop in set_merge_internal().
* Minor comment touch-ups.

Michael W. Hudson ba283e2b7f This is my patch:
[ 1181301 ] make float packing copy bytes when they can

which hasn't been reviewed, despite numerous threats to check it in
anyway if noone reviews it.  Please read the diff on the checkin list,
at least!

The basic idea is to examine the bytes of some 'probe values' to see if
the current platform is a IEEE 754-ish platform, and if so
_PyFloat_{Pack,Unpack}{4,8} just copy bytes around.

The rest is hair for testing, and tests.

Anthony Baxter 9ceaa72ebe Patch #975056 - fixes for restartable signals on *BSD. In addition,
a few remaining calls to signal() were converted to PyOS_setsig().

Tim Peters 7f468f29f4 SF patch 1044089: New C API function PyEval_ThreadsInitialized(), by Nick
Coghlan, for determining whether PyEval_InitThreads() has been called.
Also purged the undocumented+unused _PyThread_Started int.

Michael W. Hudson 30ea2f223f This closes patch:
[ 960406 ] unblock signals in threads

although the changes do not correspond exactly to any patch attached to
that report.

Non-main threads no longer have all signals masked.

A different interface to readline is used.

The handling of signals inside calls to PyOS_Readline is now rather
different.

These changes are all a bit scary!  Review and cross-platform testing
much appreciated.

Skip Montanaro 7befb9966e remove support for missing ANSI C header files (limits.h, stddef.h, etc). 2004-02-10 16:50:21 +00:00
Tim Peters 1d7323e4e7 Py_Finalize(): disabled the second call of cyclic gc, and added extensive
comments about why both calls to cyclic gc here can cause problems.

I'll backport to 2.3 maint.  Since the calls were introduced in 2.3,
that will be the end of it.

Michael W. Hudson 68debc935b Fix refcounting and cut & paste error (?) in last checkin.
This should go onto release23-maint, too.

Martin v. Löwis a2c17c5820 Move initialization of sys.std{in,out}.encoding to Py_Initialize.
Verify that the encoding actually exists. Fixes #775985.
Will backport to 2.3.

Mark Hammond 5f4e8ca376 Correct previous patch looking for warnings module: sys.modules, not
sys.__modules__.
2003-07-16 01:54:38 +00:00
Mark Hammond edd07737d7 Fix [ 771097 ] frozen programs fail due to implicit import of "warnings".
If the initial import of warnings fails, clear the error.  When the module
is actually needed, if the original import failed, see if it has managed
to find its way to sys.modules yet and if so, remember it.

Mark Hammond 6cb9029a22 PyGILState cleanup was too early - destructors called via module cleanup may use the API. 2003-04-22 11:18:00 +00:00
Tim Peters cf615b5275 handle_system_exit(): This leaked the current exception info, in
particular leaving the traceback object (and everything reachable
from it) alive throughout shutdown.  The patch is mostly from Guido.

Bugfix candidate.
2003-04-19 18:47:02 +00:00
Mark Hammond 8d98d2cb95 New PyGILState_ API - implements pep 311, from patch 684256. 2003-04-19 15:41:53 +00:00
Tim Peters 269b2a6797 _Py_PrintReferences(): Changed to print object address at start of each
new line.

New pvt API function _Py_PrintReferenceAddresses():  Prints only the
addresses and refcnts of the live objects.  This is always safe to call,
because it has no dependence on Python's C API.

Py_Finalize():  If envar PYTHONDUMPREFS is set, call (the new)
_Py_PrintReferenceAddresses() right before dumping final pymalloc stats.
We can't print the reprs of the objects here because too much of the
interpreter has been shut down.  You need to correlate the addresses
displayed here with the object reprs printed by the earlier
PYTHONDUMPREFS call to _Py_PrintReferences().
2003-04-17 19:52:29 +00:00
Guido van Rossum e13ddc9ec8 - New C API PyGC_Collect(), same as calling gc.collect().
- Call this in Py_Finalize().
- Expand the Misc/NEWS text on PY_LONG_LONG.

Guido van Rossum 66ebd91244 A missing piece of the PEP 269 patch: add PyParser_SetError(), a
