* - Finally fixed the bug in compile() and exec where a string endingGuido van Rossum2003-02-132-0/+3
| | | | | | | | | with an indented code block but no newline would raise SyntaxError. This would have been a four-line change in parsetok.c... Except codeop.py depends on this behavior, so a compilation flag had to be invented that causes the tokenizer to revert to the old behavior; this required extra changes to 2 .h files, 2 .c files, and 2 .py files. (Fixes SF bug #501622.)

| | | | Incorporated nnorwitz's comment re. Py__USING_UNICODE.
* Small function call optimization and special build option for call stats.Jeremy Hylton2003-02-052-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | -DCALL_PROFILE: Count the number of function calls executed. When this symbol is defined, the ceval mainloop and helper functions count the number of function calls made. It keeps detailed statistics about what kind of object was called and whether the call hit any of the special fast paths in the code. Optimization: When we take the fast_function() path, which seems to be taken for most function calls, and there is minimal frame setup to do, avoid call PyEval_EvalCodeEx(). The eval code ex function does a lot of work to handle keywords args and star args, free variables, generators, etc. The inlined version simply allocates the frame and copies the arguments values into the frame. The optimization gets a little help from compile.c which adds a CO_NOFREE flag to code objects that don't have free variables or cell variables. This change allows fast_function() to get into the fast path with fewer tests. I measure a couple of percent speedup in pystone with this change, but there's surely more that can be done.
* Provide __module__ attributes for functions defined in C and Python.Jeremy Hylton2003-01-312-1/+8
| | | | | | | | | | | | | | __module__ is the string name of the module the function was defined in, just like __module__ of classes. In some cases, particularly for C functions, the __module__ may be None. Change PyCFunction_New() from a function to a macro, but keep an unused copy of the function around so that we don't change the binary API. Change pickle's save_global() to use whichmodule() if __module__ is None, but add the __module__ logic to whichmodule() since it might be used outside of pickle.
* _PyLong_NumBits(): The definition of this was too specific to the quirkyTim Peters2003-01-311-5/+11
| | | | | | | | | needs of pickling longs. Backed off to a definition that's much easier to understand. The pickler will have to work a little harder, but other uses are more likely to be correct <0.5 wink>. _PyLong_Sign(): New teensy function to characterize a long, as to <0, ==0, or >0.
* Added new private API function _PyLong_NumBits. This will be used at theTim Peters2003-01-281-0/+11
| | | | | | | start for the C implemention of new pickle LONG1 and LONG4 opcodes (the linear-time way to pickle a long is to call _PyLong_AsByteArray, but the caller has no idea how big an array to allocate, and correct calculation is a bit subtle).
* SF bug #670229: doc improvement for cStringIO.hRaymond Hettinger2003-01-191-5/+12
| | | | Gernot Hillier added more detail to the internal API documentation.
* It turns out that some calls return AEDesc records that are "borrowed",Jack Jansen2003-01-171-0/+1
| | | | | | | the AEDesc data shouldn't be disposed when the Python object is. Added a C call AEDesc_NewBorrowed() to create these objects and a Python method old=AEDesc.AutoDispose(onoff) to change auto-dispose state.

* Got rid of the timetz type entirely. This was a bit trickier than ITim Peters2003-01-101-12/+17
| | | | | | | hoped it would be, but not too bad. A test had to change: time.__setstate__() can no longer add a non-None tzinfo member to a time object that didn't already have one, since storage for a tzinfo member doesn't exist in that case.
* Patch #661760: Cygwin auto-import module patchJason Tishler2003-01-061-1/+5
| | | | | | | | | | | | The attached patch enables shared extension modules to build cleanly under Cygwin without moving the static initialization of certain function pointers (i.e., ones exported from the Python DLL core) to a module initialization function. Additionally, this patch fixes the modules that have been changed in the past to accommodate Cygwin.
* Move _PyInt_Init() into pythonrun.h, since all the other _Init()Neal Norwitz2003-01-012-1/+1

* SF #561244, Micro optimizationsNeal Norwitz2002-12-302-0/+2
| | | | | | Initialize the small integers and __builtins__ in startup. This removes some if conditions. Change XDECREF to DECREF for values which shouldn't be NULL.
* PEP 302 + zipimport:Just van Rossum2002-12-301-0/+1
| | | | | | | | | | | | | - new import hooks in import.c, exposed in the sys module - new module called 'zipimport' - various changes to allow bootstrapping from zip files I hope I didn't break the Windows build (or anything else for that matter), but then again, it's been sitting on sf long enough... Regarding the latest discussions on python-dev: zipimport sets pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as /path/to/Archive.zip/subdir/ are supported again.
* Apparently FreeBSD enables some HW floating-point exceptions by default.Tim Peters2002-12-281-5/+10
| | | | | | | This can cause core dumps when Python runs. Python relies on the 754- (and C99-) mandated default "non-stop" mode for FP exceptions. This patch from Ben Laurie disables at least one FP exception on FreeBSD at Python startup time.

* SF 548651: Fix the METH_CLASS implementation.Tim Peters2002-12-091-0/+1
| | | | | | | Most of these patches are from Thomas Heller, with long lines folded by Tim. The change to test_descr.py is from Guido. See the bug report. Not a bugfix candidate -- METH_CLASS is new in 2.3.

(Too bad n_nchildren can't be made an unsigned short, but test/test_longexp.py specifically tests for more than 2**16 subtrees at one level.) I don't expect any binary compatibility issues here, unless someone has an old binary of parsermodule.so saved away.
* Use Py_GCC_ATTRIBUTE instead of __attribute__. Compilers other than GCCNeil Schemenauer2002-09-155-10/+12

* A slight change to SET_LINENO-less tracing.Michael W. Hudson2002-09-111-0/+2

* replace thread state objects' ticker and checkinterval fields with twoSkip Montanaro2002-09-032-2/+4

* Further SET_LINENO reomval fixes. See comments in patch #587933.Michael W. Hudson2002-08-301-3/+0
| | | | | | | | | | Use a slightly different strategy to determine when not to call the line trace function. This removes the need for the RETURN_NONE opcode, so that's gone again. Update docs and comments to match. Thanks to Neal and Armin! Also add a test suite. This should have come with the original patch...
* SF patch 576101, by Oren Tirosh: alternative implementation ofGuido van Rossum2002-08-192-4/+15
| | | | | | | | interning. I modified Oren's patch significantly, but the basic idea and most of the implementation is unchanged. Interned strings created with PyString_InternInPlace() are now mortal, and you must keep a reference to the resulting string around; use the new function PyString_InternImmortal() to create immortal interned strings.
