Neal Norwitz 9ac8953568 Handle malloc failure.
Klocwork 281
2006-08-13 18:13:36 +00:00
Neal Norwitz ccc56c7c96 Really address the issue of where to place the assert for leftblock.
(Followup of Klocwork 274)

Neal Norwitz 20745b1a70 Handle failure from PyModule_GetDict() (Klocwork 208).
Fix a bunch of refleaks in the init of the module.  This would only be found
when running python -v.

Neal Norwitz ee7c8f9af8 It's very unlikely, though possible that source is not a string. Verify
that PyString_AsString() returns a valid pointer.  (The problem can
arise when zlib.decompress doesn't return a string.)

Neal Norwitz 56423e5762 Fix segfault when doing string formatting on subclasses of long if
__oct__, __hex__ don't return a string.

Neal Norwitz 3cb31ac704 cpathname could be NULL if it was longer than MAXPATHLEN. Don't try
to write the .pyc to NULL.

Check results of PyList_GetItem() and PyModule_GetDict() are not NULL.

Neal Norwitz b09f4f578f Handle a whole lot of failures from PyString_FromInternedString().
Should fix most of Klocwork 234-272.

Neal Norwitz bfa5f0bb5d SF bug #1539336, distutils example code missing 2006-08-13 00:20:49 +00:00
Neal Norwitz 1872b1c01f Fix a couple of bugs exposed by the new __index__ code. The 64-bit buildbots
were failing due to inappropriate clipping of numbers larger than 2**31
with new-style classes. (typeobject.c)  In reviewing the code for classic
classes, there were 2 problems.  Any negative value return could be returned.
Always return -1 if there was an error.  Also make the checks similar
with the new-style classes.  I believe this is correct for 32 and 64 bit
boxes, including Windows64.

Add a test of classic classes too.
2006-08-12 18:44:06 +00:00
Neal Norwitz 8a87f5d37e Patch #1538606, Patch to fix __index__() clipping.
I modified this patch some by fixing style, some error checking, and adding
XXX comments.  This patch requires review and some changes are to be expected.
I'm checking in now to get the greatest possible review and establish a
baseline for moving forward.  I don't want this to hold up release if possible.

Georg Brandl f3e304297e Repair logging test spew caused by rev. 51206. 2006-08-12 08:32:02 +00:00
Tim Peters 953c1897d2 Ah, fudge. One of the prints here actually "shouldn't be"
protected by "if verbose:", which caused the test to fail on
all non-Windows boxes.

Note that I deliberately didn't convert this to unittest yet,
because I expect it would be even harder to debug this on Tru64
after conversion.

Tim Peters 1742f3331f test_signal: Signal handling on the Tru64 buildbot
appears to be utterly insane.  Plug some theoretical
insecurities in the test script:

- Verify that the SIGALRM handler was actually installed.

- Don't call alarm() before the handler is installed.

- Move everything that can fail inside the try/finally,
  so the test cleans up after itself more often.

- Try sending all the expected signals in
  force_test_exit(), not just SIGALRM.  Since that was
  fixed to actually send SIGALRM (instead of invisibly
  dying with an AttributeError), we've seen that sending
  SIGALRM alone does not stop this from hanging.

- Move the "kill the child" business into the finally
  clause, so the child doesn't survive test failure
  to send SIGALRM to other tests later (there are also
  baffling SIGALRM-related failures in test_socket).

- Cancel the alarm in the finally clause -- if the
  test dies early, we again don't want SIGALRM showing
  up to confuse a later test.

Alas, this still relies on timing luck wrt the spawned
script that sends the test signals, but it's hard to see
how waiting for seconds can so often be so unlucky.

test_threadedsignals:  curiously, this test never fails
on Tru64, but doesn't normally signal SIGALRM.  Anyway,
fixed an obvious (but probably inconsequential) logic
error.

Neal Norwitz ebcf8759bb Verify verdat which is returned from malloc is not NULL.
Ensure we don't pass NULL to free.

Neal Norwitz 421c1319ad Whoops, how did that get in there. :-) Revert all the parts of 51227 that were not supposed to go it. Only Modules/_ctypes/cfields.c was supposed to be changed 2006-08-12 02:12:30 +00:00
Neal Norwitz 6b4953fd3d Check returned pointer is valid.
Klocwork #233
2006-08-12 02:06:34 +00:00
Neal Norwitz b45f351832 I'm not sure why this code allocates this string for the error message.
I think it would be better to always use snprintf and have the format
limit the size of the name appropriately (like %.200s).

Klocwork #340
2006-08-12 01:57:47 +00:00
Neal Norwitz ef0de023db Try to handle a malloc failure. I'm not entirely sure this is correct.
There might be something else we need to do to handle the exception.

Neal Norwitz 9cd3c34b6a Move the assert which checks for a NULL pointer first.
Klocwork #274.
2006-08-12 01:51:12 +00:00
Neal Norwitz e0a81afb10 If _stat_float_times is false, we will try to INCREF ival which could be NULL.
Return early in that case.  The caller checks for PyErr_Occurred so this
should be ok.

Klocwork #297
2006-08-12 01:50:38 +00:00
Neal Norwitz 6bf1a8fe8b Handle NULL nodes while parsing. I'm not entirely sure this is correct.
There might be something else that needs to be done to setup the error.

Klocwork #295.
2006-08-12 01:49:12 +00:00
Neal Norwitz edb2168079 This code is actually not used unless WITHOUT_COMPLEX is defined.
However, there was no error checking that PyFloat_FromDouble returned
a valid pointer.  I believe this change is correct as it seemed
to follow other code in the area.

Klocwork # 292.
2006-08-12 01:47:59 +00:00
Neal Norwitz 43bd4db933 It's highly unlikely, though possible for PyEval_Get*() to return NULLs.
So be safe and do an XINCREF.

Klocwork # 221-222.
2006-08-12 01:46:42 +00:00
Neal Norwitz 84167d09cd Even though _Py_Mangle() isn't truly public anyone can call it and
there was no verification that privateobj was a PyString.  If it wasn't
a string, this could have allowed a NULL pointer to creep in below and crash.

I wonder if this should be PyString_CheckExact?  Must identifiers be strings
or can they be subclasses?

Klocwork #275
2006-08-12 01:45:47 +00:00
Neal Norwitz 6f5ff3f3eb Klocwork made another run and found a bunch more problems.
This is the first batch of fixes that should be easy to verify based on context.

This fixes problem numbers: 220 (ast), 323-324 (symtable),
321-322 (structseq), 215 (array), 210 (hotshot), 182 (codecs), 209 (etree).

Thomas Heller 2a899c8b76 When a ctypes C callback function is called, zero out the result
storage before converting the result to C data.  See the comment in
the code for details.

Provide a better context for errors when the conversion of a callback
function's result cannot be converted.

Neal Norwitz 003c9e2952 Fix the failures on cygwin (2006-08-10 fixed the actual locking issue).
The first hunk changes the colon to an ! like other Windows variants.
We need to always wait on the child so the lock gets released and
no other tests fail.  This is the try/finally in the second hunk.
2006-08-11 06:09:41 +00:00
Tim Peters 8b8c59cf1d force_test_exit(): This has been completely ineffective
at stopping test_signal from hanging forever on the Tru64
buildbot.  That could be because there's no such thing as
signal.SIGALARM.  Changed to the idiotic (but standard)
signal.SIGALRM instead, and added some more debug output.
2006-08-11 03:49:10 +00:00
Tim Peters 08574770c5 test_PyThreadState_SetAsyncExc(): This is failing on some
64-bit boxes.  I have no idea what the ctypes docs mean
by "integers", and blind-guessing here that it intended to
mean the signed C "int" type, in which case perhaps I can
repair this by feeding the thread id argument to type
ctypes.c_long().

Also made the worker thread daemonic, so it doesn't hang
Python shutdown if the test continues to fail.

Tim Peters b7ad1eb2c6 Whitespace normalization broke test_cgi, because a line
of quoted test data relied on preserving a single trailing
blank.  Changed the string from raw to regular, and forced
in the trailing blank via an explicit \x20 escape.

Tim Peters 4643c2fda1 Followup to bug #1069160.
PyThreadState_SetAsyncExc():  internal correctness changes wrt
refcount safety and deadlock avoidance.  Also added a basic test
case (relying on ctypes) and repaired the docs.

Tim Peters b2dd1a3906 test_copytree_simple(): This was leaving behind two new temp
directories each time it ran, at least on Windows.

Several changes:  explicitly closed all files; wrapped long
lines; stopped suppressing errors when removing a file or
directory fails (removing /shouldn't/ fail!); and changed
what appeared to be incorrect usage of os.removedirs() (that
doesn't remove empty directories at and /under/ the given
path, instead it must be given an empty leaf directory and
then deletes empty directories moving /up/ the path -- could
be that the conceptually simpler shutil.rmtree() was really
actually intended here).
