Neal Norwitz c173b488dc Add some asserts and update comments 2006-07-30 19:18:13 +00:00
Neal Norwitz 07aadb14f3 Add PyErr_WarnEx() so C code can pass the stacklevel to warnings.warn().
This provides the proper warning for struct.pack().
PyErr_Warn() is now deprecated in favor of PyErr_WarnEx().
As mentioned by Tim Peters on python-dev.

Phillip J. Eby f7575d0cb7 Bug #1529871: The speed enhancement patch #921466 broke Python's compliance
with PEP 302.  This was fixed by adding an ``imp.NullImporter`` type that is
used in ``sys.path_importer_cache`` to cache non-directory paths and avoid
excessive filesystem operations during imports.

Tim Peters bc24eee333 Bug #1521947: possible bug in mystrtol.c with recent gcc.
In general, C doesn't define anything about what happens when
an operation on a signed integral type overflows, and PyOS_strtol()
did several formally undefined things of that nature on signed
longs.  Some version of gcc apparently tries to exploit that now,
and PyOS_strtol() could fail to detect overflow then.

Tried to repair all that, although it seems at least as likely to me
that we'll get screwed by bad platform definitions for LONG_MIN
and/or LONG_MAX now.  For that reason, I don't recommend backporting
this.

Note that I have no box on which this makes a lick of difference --
can't really test it, except to note that it didn't break anything
on my boxes.

Silent change:  PyOS_strtol() used to return the hard-coded 0x7fffffff
in case of overflow.  Now it returns LONG_MAX.  They're the same only on
32-bit boxes (although C doesn't guarantee that either ...).

Georg Brandl 5f135787ec Part of bug #1523610: fix miscalculation of buffer length.
Also add a guard against NULL in converttuple and add a test case
(that previously would have crashed).

will backport.

Neal Norwitz f71847e645 If the for loop isn't entered, entryblock will be NULL. If passed
to stackdepth_walk it will be dereffed.

Not sure if I found with failmalloc or Klockwork #55.

Tim Peters 112aad3630 SF bug 1524317: configure --without-threads fails to build
Moved the code for _PyThread_CurrentFrames() up, so it's no longer
in a huge "#ifdef WITH_THREAD" block (I didn't realize it /was/ in
one).

Changed test_sys's test_current_frames() so it passes with or without
thread supported compiled in.

Note that test_sys fails when Python is compiled without threads,
but for an unrelated reason (the old test_exit() fails with an
indirect ImportError on the `thread` module).  There are also
other unrelated compilation failures without threads, in extension
modules (like ctypes); at least the core compiles again.

Do we really support --without-threads?  If so, there are several
problems remaining.

Neal Norwitz a5e4f22bfb Reported by Klocwork #151.
v2 can be NULL if exception2 is NULL.  I don't think that condition can happen,
but I'm not sure it can't either.  Now the code will protect against either
being NULL.

Tim Peters 32a8361f2d After approval from Anthony, merge the tim-current_frames
branch into the trunk.  This adds a new sys._current_frames()
function, which returns a dict mapping thread id to topmost
thread stack frame.

Neal Norwitz 28746aba9b On 64 bit systems, int literals that use less than 64 bits are now ints
rather than longs.  This also fixes the test for eval(-sys.maxint - 1).

Georg Brandl 98251f8a2f Argh. "integer" is a very confusing word ;)
Actually, checking for INT_MAX and INT_MIN is correct since
the format code explicitly handles a C "int".

Tim Peters 02f1d0dc78 _PySys_Init(): It's rarely a good idea to size a buffer to the
exact maximum size someone guesses is needed.  In this case, if
we're really worried about extreme integers, then "cp%d" can
actually need 14 bytes (2 for "cp" + 1 for \0 at the end +
11 for -(2**31-1)).  So reserve 128 bytes instead -- nothing is
actually saved by making a stack-local buffer tiny.
2006-06-06 00:25:07 +00:00
Brett Cannon 4f7a7220c1 Add 3 more bytes to a buffer to cover constants in string and null byte on top of 10 possible digits for an int.
Closes bug #1501223.

Tim Peters 28eeefe566 Revert revisions:
46640 Patch #1454481:  Make thread stack size runtime tunable.
46647 Markup fix

The first is causing many buildbots to fail test runs, and there
are multiple causes with seemingly no immediate prospects for
repairing them.  See python-dev discussion.

Note that a branch can (and should) be created for resolving these
problems, like

svn copy svn+ssh://svn.python.org/python/trunk -r46640 svn+ssh://svn.python.org/python/branches/NEW_BRANCH

followed by merging rev 46647 to the new branch.
