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.
2003-04-17 17:29:22 +00:00
Guido van Rossum 66ebd91244 A missing piece of the PEP 269 patch: add PyParser_SetError(), a
wrapper around err_input().
2003-04-17 16:02:26 +00:00
Tim Peters d08e3824d4 Trimmed trailing whitespace. 2003-04-17 15:24:21 +00:00
Tim Peters 9cf25ce3a0 Py_Finalize(): Reverted recent changes that tried to move the
PYTHONDUMPREFS output after most teardown.  Attempts to use
PYTHONDUMPREFS with the Zope3 test suite died with Py_FatalError(),
since _Py_PrintReferences() can end up executing arbitrary Python code
(for objects that override __repr__), and that requires an intact
interpreter.
2003-04-17 15:21:01 +00:00
Guido van Rossum 0fc8f00252 - pythunrun.c, Py_Finalize(): move the call to _Py_PrintReferences()
even farther down, to just before the call to
  _PyObject_DebugMallocStats().  This required the following changes:

- pystate.c, PyThreadState_GetDict(): changed not to raise an
  exception or issue a fatal error when no current thread state is
  available, but simply return NULL without raising an exception
  (ever).

- object.c, Py_ReprEnter(): when PyThreadState_GetDict() returns NULL,
  don't raise an exception but return 0.  This means that when
  printing a container that's recursive, printing will go on and on
  and on.  But that shouldn't happen in the case we care about (see
  first bullet).

- Updated Misc/NEWS and Doc/api/init.tex to reflect changes to
  PyThreadState_GetDict() definition.
2003-04-15 15:12:39 +00:00
Guido van Rossum d922fa46ce Move the call to _Py_PrintReferences() a bit further down. This
prevents it from showing stuff (like codec state) that is cleared when
the interpreter state is cleared.

Neal Norwitz 5c16c7b014 Move declaration of enc to scope where it is used 2003-04-10 21:53:14 +00:00
Gustavo Niemeyer 5ddd4c3f77 Fixed SF bug #663074. The codec system was using global static
variables to store internal data. As a result, any atempts to use the
unicode system with multiple active interpreters, or successive
interpreter executions, would fail.

Now that information is stored into members of the PyInterpreterState
structure.

Martin v. Löwis 73d538b9c6 Always initialize Py_FileSystemDefaultEncoding on Unix in Py_Initialize,
and not as a side effect of setlocale. Expose it as sys.getfilesystemencoding.
Adjust test case.

Just van Rossum 5bfba3aeb9 Addendum to #683658:
import warnings.py _after_ site.py has run. This ensures that site.py
is again the first .py to be imported, giving it back full control over
sys.path.
2003-02-25 20:25:12 +00:00
Mark Hammond a43fd0c899 Fix bug 683658 - PyErr_Warn may cause import deadlock. 2003-02-19 00:33:33 +00:00
Guido van Rossum 4b499dd3fb - Finally fixed the bug in compile() and exec where a string ending
with an indented code block but no newline would raise SyntaxError.
  This would have been a four-line change in parsetok.c...  Except
  codeop.py depends on this behavior, so a compilation flag had to be
  invented that causes the tokenizer to revert to the old behavior;
  this required extra changes to 2 .h files, 2 .c files, and 2 .py
  files.  (Fixes SF bug #501622.)

Jack Jansen a038270590 MacPython-OS9 has had an abort() function for quite a while now, so there's no reason to stall in an endless loop, just call abort() on a fatal error. 2003-01-24 16:17:18 +00:00
Martin v. Löwis d7ceb222bd Patch #671459: Invoke import hooks in Py_NewInterpreter. 2003-01-22 09:00:38 +00:00

Neal Norwitz c91ed400e0 SF #561244, Micro optimizations
Initialize the small integers and __builtins__ in startup.
This removes some if conditions.
Change XDECREF to DECREF for values which shouldn't be NULL.
2002-12-30 22:29:22 +00:00
Just van Rossum 52e14d640b 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.
2002-12-30 22:08:05 +00:00
Jack Jansen 72f3b7a5de Added missing casts. 2002-12-13 15:23:10 +00:00
Martin v. Löwis 95292d6caa Constify filenames and scripts. Fixes #651362. 2002-12-11 14:04:59 +00:00
Neil Schemenauer 89350a41b9 Remove _Py_ResetReferences. Fixes bug #529750 "Circular reference makes
Py_Init crash".  refchain cannot be cleared because objects can live across
Py_Finalize() and Py_Initialize() if they are kept alive by circular
references.

Fred Drake 8ed0204bc9 If we have a filename and __main__.__file__ hasn't already been set,
set it.
Closes SF issue #624729.

Tim Peters 92e4dd8657 s/_alloca/alloca/g; Windows doesn't need the former, at least not unless
__STDC__ is defined (or something like that ...).

Martin v. Löwis 00f1e3f5a5 Patch #534304: Implement phase 1 of PEP 263. 2002-08-04 17:29:52 +00:00
Tim Peters 34b2569327 _Py_AskYesNo(): Removed this function. It was defined only in a
Py_TRACE_REFS build, but wasn't referenced.
2002-07-09 18:22:55 +00:00
Thomas Heller 6b17abf6c0 Fix SF Bug 564931: compile() traceback must include filename. 2002-07-09 09:23:27 +00:00
Tim Peters 7c321a80f9 The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: added
more trivial lexical helper macros so that uses of these guys expand
to nothing at all when they're not enabled.  This should help sub-
standard compilers that can't do a good job of optimizing away the
previous "(void)0" expressions.

Py_DECREF:  There's only one definition of this now.  Yay!  That
was that last one in the family defined multiple times in an #ifdef
maze.

Py_FatalError():  Changed the char* signature to const char*.

_Py_NegativeRefcount():  New helper function for the Py_REF_DEBUG
expansion of Py_DECREF.  Calling an external function cuts down on
the volume of generated code.  The previous inline expansion of abort()
didn't work as intended on Windows (the program often kept going, and
the error msg scrolled off the screen unseen).  _Py_NegativeRefcount
calls Py_FatalError instead, which captures our best knowledge of
how to abort effectively across platforms.

Martin v. Löwis 6238d2b024 Patch #569753: Remove support for WIN16.
Rename all occurrences of MS_WIN32 to MS_WINDOWS.
2002-06-30 15:26:10 +00:00
Jeremy Hylton 1b0bf9b761 Ignore SIGXFSZ.
The SIGXFSZ signal is sent when the maximum file size limit is
exceeded (RLIMIT_FSIZE).  Apparently, it is also sent when the 2GB
file limit is reached on platforms without large file support.

The default action for SIGXFSZ is to terminate the process and dump
core.  When it is ignored, the system call that caused the limit to be
exceeded returns an error and sets errno to EFBIG.  Python
always checks errno on I/O syscalls, so there is nothing to do with
the signal.
2002-04-23 20:31:01 +00:00
Tim Peters 0e871188e8 _PyObject_DebugDumpStats: renamed to _PyObject_DebugMallocStats.
Added code to call this when PYMALLOC_DEBUG is enabled, and envar
PYTHONMALLOCSTATS is set, whenever a new arena is obtained and once
late in the Python shutdown process.
