Amaury Forgeot d'Arc e4921fec01 Issue2378: pdb would delete free variables when stepping into a class statement.
The problem was introduced by r53954, the correction is to restore the symmetry between
PyFrame_FastToLocals and PyFrame_LocalsToFast

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.

Christian Heimes 593daf545b Renamed PyString to PyBytes 2008-05-26 12:51:38 +00:00
Christian Heimes 3b718a79af Implemented Martin's suggestion to clear the free lists during the garbage collection of the highest generation. 2008-02-14 12:47:33 +00:00
Christian Heimes 5b970ad483 Unified naming convention for free lists and their limits. All free lists
in Object/ are named ``free_list``, the counter ``numfree`` and the upper
limit is a macro ``PyName_MAXFREELIST`` inside an #ifndef block.

The chances should make it easier to adjust Python for platforms with
less memory, e.g. mobile phones.

Jeremy Hylton 759410b372 Do not copy free variables to locals in class namespaces.
Fixes bug 1569356, but at the cost of a minor incompatibility in
locals().  Add test that verifies that the class namespace is not
polluted.  Also clarify the behavior in the library docs.

Along the way, cleaned up the dict_to_map and map_to_dict
implementations and added some comments that explain what they do.

Neal Norwitz 1adbb50701 Move the initialization of some pointers earlier. The problem is
that if we call Py_DECREF(frame) like we do if allocating locals fails,
frame_dealloc() will try to use these bogus values and crash.

Neal Norwitz 7d5b6e8991 f_code can't be NULL based on Frame_New and other code that derefs it.

Richard Jones 7c88dcc5ab Merge from rjones-funccall branch.
Applied patch zombie-frames-2.diff from sf patch 876206 with updates for
Python 2.5 and also modified to retain the free_list to avoid the 67%
slow-down in pybench recursion test. 5% speed up in function call pybench.

Tim Peters adcd25e7fa frame_clear(): Explain why it's important to make the frame
look dead right at the start.  Use Py_CLEAR for four more
frame members.
2006-04-15 03:30:08 +00:00
Tim Peters de2acf6512 frame_traverse(): Use the standard Py_VISIT macro.
Py_VISIT:  cast the `op` argument to PyObject* when calling
`visit()`.  Else the caller has to pay too much attention to
this silly detail (e.g., frame_traverse needs to traverse
`struct _frame *` and `PyCodeObject *` pointers too).

Phillip J. Eby 8ebb28df3a Fix SF#1470508: crash in generator cycle finalization. There were two
problems: first, PyGen_NeedsFinalizing() had an off-by-one bug that
prevented it from ever saying a generator didn't need finalizing, and
second, frame objects cleared themselves in a way that caused their
owning generator to think they were still executable, causing a double
deallocation of objects on the value stack if there was still a loop
on the block stack.  This revision also removes some unnecessary
close() operations from test_generators that are now appropriately
handled by the cycle collector.

Neal Norwitz 2aa9a5dfdd Use macro versions instead of function versions when we already know the type.
This will hopefully get rid of some Coverity warnings, be a hint to
developers, and be marginally faster.

Some asserts were added when the type is currently known, but depends
on values from another function.

Jeremy Hylton 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.

Raymond Hettinger 214b1c3aae SF Bug #215126: Over restricted type checking on eval() function
The builtin eval() function now accepts any mapping for the locals argument.
Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing
down the normal case.  My timings so no measurable impact.

Armin Rigo 76beca957f Two forgotten Py_DECREF() for two out-of-memory conditions. 2004-01-27 16:08:07 +00:00
Jeremy Hylton e4b9d8c2ba Removing bogus Py_DECREF() reported by Armin Rigo (SF bug 812353).
Even if a new dict is generated for locals, it is stored in
f->f_locals.

Jeremy Hylton bd5cbf866f Refactor the logic for setting f_builtins.
For the case where the current globals match the previous frame's
globals, eliminates three tests in two if statements.  For the case
where we just get __builtins__ from a module, eliminate a couple of
tests.

Michael W. Hudson cfd3884882 This is Richie Hindle's patch
[ 643835 ] Set Next Statement for Python debuggers

with a few tweaks by me: adding an unsigned or two, mentioning that
not all jumps are allowed in the doc for pdb, adding a NEWS item and
a note to whatsnew, and AuCTeX doing something cosmetic to libpdb.tex.

Many sundry changes to document and adapt to this change.

Guido van Rossum f4be427c46 Tim found that once test_longexp has run, test_sort takes very much
longer to run than normal.  A profiler run showed that this was due to
PyFrame_New() taking up an unreasonable amount of time.  A little
thinking showed that this was due to the while loop clearing the space
available for the stack.  The solution is to only clear the local
variables (and cells and free variables), not the space available for
the stack, since anything beyond the stack top is considered to be
garbage anyway.  Also, use memset() instead of a while loop counting
backwards.  This should be a time savings for normal code too!  (By a
probably unmeasurable amount. :-)
