Mark Dickinson 504a151c82 Issue #6603: Fix --with-tsc build failures on x86-64 that resulted
from a gcc inline assembler peculiarity. (gcc's "A" constraint
apparently means 'rax or rdx' in 64-bit mode, not edx:eax
or rdx:rax as one might expect.)

Mark Dickinson 09823a2e21 Deprecate PyOS_ascii_strtod and PyOS_ascii_atof, and document the replacement function PyOS_string_to_double. 2009-10-31 09:42:39 +00:00
Benjamin Peterson ea0e3b0d60 do a backport of r75928
The added test does not fail without the patch, but we still fix the issue of
surrogates being used in wide builds where they should not be.

Eric Smith b218d289e6 Removed PyOS_ascii_atof from marshal.c, as mentioned in issue 7117. Also brings it more in line with py3k. 2009-10-27 19:42:57 +00:00

- add double endianness detection to configure script
 - add configure-time check to see whether we can use inline
   assembly to get and set x87 control word in configure script
 - add functions to get and set x87 control word in Python/pymath.c
 - add pyport.h logic to determine whether it's safe to use the

Antoine Pitrou efb60c0ceb Issue #1722344: threading._shutdown() is now called in Py_Finalize(), which
fixes the problem of some exceptions being thrown at shutdown when the
interpreter is killed. Patch by Adam Olsen.
2009-10-20 21:29:37 +00:00
Eric Smith 156692752d Removed calls to PyFloat_AsReprString.
This is in anticipation of possibly implementing issue 7117 (short float repr).
This removes the last calls to PyFloat_AsString, PyFloat_AsReprString, and
PyFloat_AsStringEx, which are unsafe.

Also, switch to defines for error values to bring this code more in line
with the py3k branch.

Mark Dickinson 7e7a3ec901 Issue #7019: Unmarshalling of bad long data could produce unnormalized
PyLongs.  Raise ValueError instead.
2009-09-29 19:01:06 +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.

Benjamin Peterson 87e5006d8c handle errors from _PyObject_LookupSpecial when __get__ fails 2009-05-25 02:40:21 +00:00
Jeffrey Yasskin 655d835415 Issue #6042:
lnotab-based tracing is very complicated and isn't documented very well.  There
were at least 3 comment blocks purporting to document co_lnotab, and none did a
very good job. This patch unifies them into Objects/lnotab_notes.txt which
tries to completely capture the current state of affairs.

I also discovered that we've attached 2 layers of patches to the basic tracing
scheme. The first layer avoids jumping to instructions that don't start a line,
to avoid problems in if statements and while loops.  The second layer
discovered that jumps backward do need to trace at instructions that don't
start a line, so it added extra lnotab entries for 'while' and 'for' loops, and
added a special case for backward jumps within the same line. I replaced these
patches by just treating forward and backward jumps differently.

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.

2009-04-24 12:46:53 +00:00
Eric Smith aca19e6a74 Backport of some of the work in r71665 to trunk. This reworks much of
int, long, and float __format__(), and it keeps their implementation
in sync with py3k.

Also added PyOS_double_to_string. This is the "fallback" version
that's also available in trunk, and should be kept in sync with that
code. I'll add an issue to document PyOS_double_to_string in the C
API.

There are many internal cleanups. Externally visible changes include:

- Implement PEP 378, Format Specifier for Thousands Separator, for
  floats, ints, and longs.

- Issue #5515: 'n' formatting for ints, longs, and floats handles
  leading zero formatting poorly.

- Issue #5772: For float.__format__, don't add a trailing ".0" if
  we're using no type code and we have an exponent.

Re http://bugs.python.org/issue4315

The symbol table used the same name dictionaries to recursively
analyze each of its child blocks, even though the dictionaries are
modified during analysis.  The fix is to create new temporary
dictionaries via the analyze_child_block().  The only information that
needs to propagate back up is the names of the free variables.

Add more comments and break out a helper function.  This code doesn't
get any easier to understand when you only look at it once a year.

Amaury Forgeot d'Arc 05e344954d #3743: PY_FORMAT_SIZE_T is designed for the OS "printf" functions, not for
PyString_FromFormat which has an independent implementation, and uses "%zd".

This makes a difference on win64, where printf needs "%Id" to display
64bit values. For example, queue.__repr__ was incorrect.
