Serhiy Storchaka c06a6d0958 Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size.

__slots__ defined.

Mark Dickinson 154b7ad07e Issue #1530559: When packing a non-integer with any integer conversion 
code using struct.pack, attempt to convert to an integer first using
the argument's __int__ method (if present).  Also raise a
DeprecationWarning for any such usage of __int__.

This fixes a regression from 2.6, where some (but not all) integer
conversion codes already used __int__.

Mark Dickinson 1c0c78c61f Fix incorrect stacklevel for DeprecationWarnings originating from the struct module. 
Also clean up related tests in test_struct.
The stacklevel fix should be backported to 2.6 once that branch is unfrozen.

Jeffrey Yasskin 7937d939b1 Fix nearly all compilation warnings under Apple gcc-4.0. Tested with OPT="-g 
-Wall -Wstrict-prototypes -Werror" in both --with-pydebug mode and --without.
There's still a batch of non-prototype warnings in Xlib.h that I don't know how
to fix.

Gregory P. Smith 9d53457e59 Merge in release25-maint r60793: 
Added checks for integer overflows, contributed by Google. Some are
 only available if asserts are left in the code, in cases where they
 can't be triggered from Python code.

Gregory P. Smith dd96db63f6 This reverts r63675 based on the discussion in this thread: 
http://mail.python.org/pipermail/python-dev/2008-June/079988.html

Python 2.6 should stick with PyString_* in its codebase.  The PyBytes_* names
in the spirit of 3.0 are available via a #define only.  See the email thread.
 2008-06-09 04:58:54 +00:00

Thomas Heller f3c0559b5e Issue 1872: Changed the struct module typecode from 't' to '?', for 
compatibility with PEP3118.
 2008-03-05 15:34:29 +00:00
Amaury Forgeot d'Arc 588ff93f13 Crashers of the day: Py_CLEAR must be used when there is a chance that the 
function can be called recursively.
This was discussed in issue1020188.

In python codebase, all occurrences of Py_[X]DECREF(xxx->yyy) are suspect,
except when they appear in tp_new or tp_dealloc functions, or when
the member cannot be of a user-defined class.
Note that tp_init is not safe.

I do have a (crashing) example for every changed line.
Is it worth adding them to the test suite?

Example:

class SpecialStr(str):
    def __del__(self):
        s.close()

import cStringIO
s = cStringIO.StringIO(SpecialStr("text"))
s.close() # Segfault

Bob Ippolito e6c9f982a0 Fix #1530559, struct.pack raises TypeError where it used to convert. 
Passing float arguments to struct.pack when integers are expected
now triggers a DeprecationWarning.
 2006-08-04 23:59:21 +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.

Martin Blais af2ae72cb2 Fixes in struct and socket from merge reviews. 
- Following Guido's comments, renamed

  * pack_to -> pack_into
  * recv_buf -> recv_into
  * recvfrom_buf -> recvfrom_into

- Made fixes to _struct.c according to Neal Norwitz comments on the checkins
  list.

- Converted some ints into the appropriate -- I hope -- ssize_t and size_t.
