Ezio Melotti 4b017bbac0 #6881 - fixed wrong return type; improved the formatting 2009-09-20 07:10:39 +00:00
Georg Brandl 579a358e61 #6930: clarify description about byteorder handling in UTF decoder routines. 2009-09-18 21:35:59 +00:00
Thomas Wouters c4dcb3801e Fix issue #1590864, multiple threads and fork() can cause deadlocks, by 
acquiring the import lock around fork() calls. This prevents other threads
from having that lock while the fork happens, and is the recommended way of
dealing with such issues. There are two other locks we care about, the GIL
and the Thread Local Storage lock. The GIL is obviously held when calling
Python functions like os.fork(), and the TLS lock is explicitly reallocated
instead, while also deleting now-orphaned TLS data.

This only fixes calls to os.fork(), not extension modules or embedding
programs calling C's fork() directly. Solving that requires a new set of API
functions, and possibly a rewrite of the Python/thread_*.c mess. Add a
warning explaining the problem to the documentation in the mean time.

This also changes behaviour a little on AIX. Before, AIX (but only AIX) was
getting the import lock reallocated, seemingly to avoid this very same
problem. This is not the right approach, because the import lock is a
re-entrant one, and reallocating would do the wrong thing when forking while
holding the import lock.

Will backport to 2.6, minus the tiny AIX behaviour change.

Jeffrey Yasskin f7f858d141 Issue 5954, PyFrame_GetLineNumber: 
Most uses of PyCode_Addr2Line
(http://www.google.com/codesearch?q=PyCode_Addr2Line) are just trying to get
the line number of a specified frame, but there's no way to do that directly.
Forcing people to go through the code object makes them know more about the
guts of the interpreter than they should need.

The remaining uses of PyCode_Addr2Line seem to be getting the line from a
traceback (for example,
http://www.google.com/codesearch/p?hl=en#u_9_nDrchrw/pygame-1.7.1release/src/base.c&q=PyCode_Addr2Line),
which is replaced by the tb_lineno field.  So we may be able to deprecate
PyCode_Addr2Line entirely for external use.

Jeffrey Yasskin 1aa4700234 PyCode_NewEmpty: 
Most uses of PyCode_New found by http://www.google.com/codesearch?q=PyCode_New
are trying to build an empty code object, usually to put it in a dummy frame
object. This patch adds a PyCode_NewEmpty wrapper which lets the user specify
just the filename, function name, and first line number, instead of also
requiring lots of code internals.

Eric Smith a985a3aee4 Issue #5920: Changed format.__float__ and complex.__float__ to use a precision of 12 when using the empty presentation type. This more closely matches str()'s behavior and reduces surprises when adding alignment flags to an empty format string. Patch by Mark Dickinson. 2009-05-05 18:26:08 +00:00
Georg Brandl 2622b549d7 #5840: dont claim we dont support TLS. 2009-04-27 17:09:53 +00:00
Georg Brandl 16a57f6a34 Demote warnings to notices where appropriate, following the goal that as few "red box" warnings 
should clutter the docs as possible.  Part 1: stuff that gets merged to Py3k.

Eric Smith f254aab098 Note that the caller is resposible for freeing the result of PyOS_double_to_string. 2009-04-26 10:05:11 +00:00
Georg Brandl afb0d6ef39 Mostly formatting nits, and "and-ed together" -> "or-ed together" flags. 2009-04-26 06:01:04 +00:00
Eric Smith 068f06568b Issue #5835, deprecate PyOS_ascii_formatd. 
If anyone wants to clean up the documentation, feel free. It's my first documentation foray, and it's not that great.

Will port to py3k with a different strategy.

Jeroen Ruigrok van der Werven 691f5f17ee Issue #4129: More documentation pointers about int -> Py_ssize_t. 
Also fix up the documentation for PyObject_GC_Resize(). It seems that since
it first got documented, the documentation was actually for
_PyObject_GC_Resize().

might cause problems on 64-bit platforms.
