305480c9dc Issue 3116: fix quadratic behavior in marshal.dumps(). 2008-06-16 01:42:40 +00:00

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.

b423f02aa5 Let marshal build-up sets and frozensets one element at a time.

f6b0e4dca8 Last try for tweaking the max stack depth. 5000 was the original value, 
4000 didn't work either.  1000 does work on Windows.  If 2000 works,
that will hopefully be a reasonable balance.

4f82bc3183 Set the depth to something very small to try to determine if the 
crashes on Windows are really due to the stack size or possibly
some other problem.

Neal Norwitz
117ef0863b Reduce the max stack depth to see if this fixes the segfaults on 
Windows and some other boxes.  If this is successful, this rev should
be backported.  I'm not sure how close to the limit we should push this.

b1a9b37aa8 Fix bug in marshal where bad data would cause a segfault due to

7ccbca93a2 Forward-port of r52136,52138: a review of overflow-detecting code. 
* unified the way intobject, longobject and mystrtoul handle
  values around -sys.maxint-1.

* in general, trying to entierely avoid overflows in any computation
  involving signed ints or longs is extremely involved.  Fixed a few
  simple cases where a compiler might be too clever (but that's all
  guesswork).

* more overflow checks against bad data in marshal.c.

* 2.5 specific: fixed a number of places that were still confusing int
  and Py_ssize_t.  Some of them could potentially have caused
  "real-world" breakage.

* list.pop(x): fixing overflow issues on x was messy.  I just reverted
  to PyArg_ParseTuple("n"), which does the right thing.  (An obscure
  test was trying to give a Decimal to list.pop()... doesn't make
  sense any more IMHO)

* trying to write a few tests...

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.

7f401ef73d Fix gcc (4.0.x) warning about use of uninitialized variables. 
(PyMarshal_ReadShortFromFile() is only used in zipimport.c, I don't believe
the extra initializations will matter one way or another.)

3e0055f8c6 Merge ast-branch to head 
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

[ 1180997 ] lax error-checking in new-in-2.4 marshal stuff

df88846ebc This is my patch: 
[ 1180995 ] binary formats for marshalling floats

Adds 2 new type codes for marshal (binary floats and binary complexes), a
new marshal version (2), updates MAGIC and fiddles the de-serializing of
code objects to be less likely to clobber the real reason for failing if
it fails.

2ccea17856 Any call to marshal.dumps() with the new optional argument 'version' just 
immediately segfaults, due to a typo!  This was obviously never tested...
Added a test for it, and also fixed the documentation.

6bc06eca70 Bug #794140: cygwin builds do not embed 
The embed2.diff patch solves the user's problem by exporting the missing
symbols from the Python core so Python can be embedded in another Cygwin
application (well, at lest vim).

3e1c18ad0c Fix SF 588452: debug build crashes on marshal.dumps([128] * 1000). 
See there for a description.

Added test case.

Bugfix candidate for 2.2.x, not sure about previous versions:
probably low priority, because virtually no one runs debug builds.
