* SF patch #578297:Andrew MacIntyre2002-08-043-12/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Change the parser and compiler to use PyMalloc. Only the files implementing processes that will request memory allocations small enough for PyMalloc to be a win have been changed, which are:- - Python/compile.c - Parser/acceler.c - Parser/node.c - Parser/parsetok.c This augments the aggressive overallocation strategy implemented by Tim Peters in PyNode_AddChild() [Parser/node.c], in reducing the impact of platform malloc()/realloc()/free() corner case behaviour. Such corner cases are known to be triggered by test_longexp and test_import. Jeremy Hylton, in accepting this patch, recommended this as a bugfix candidate for 2.2. While the changes to Python/compile.c and Parser/node.c backport easily (and could go in), the changes to Parser/acceler.c and Parser/parsetok.c require other not insignificant changes as a result of the differences in the memory APIs between 2.3 and 2.2, which I'm not in a position to work through at the moment. This is a pity, as the Parser/parsetok.c changes are the most important after the Parser/node.c changes, due to the size of the memory requests involved and their frequency.
* XXXROUNDUP(): Turns out this fixed Andrew MacIntyre's memory-mgmtTim Peters2002-07-151-10/+33
| | | | | | | | | | disaster too, so this change is here to stay. Beefed up the comments and added some stats Andrew reported. Also a small change to the macro body, to make it obvious how XXXROUNDUP(0) ends up returning 0. See SF patch 578297 for context. Not a bugfix candidate, as the functional changes here have already been backported to the 2.2 line (this patch just improves clarity).
* Fix bug 439992 - [win32] KeyboardInterrupt Not Caught.Mark Hammond2002-07-141-0/+33

* The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: addedTim Peters2002-07-091-1/+1
| | | | | | | | | | | | | | | | | | | | | more trivial lexical helper macros so that uses of these guys expand to nothing at all when they're not enabled. This should help sub- standard compilers that can't do a good job of optimizing away the previous "(void)0" expressions. Py_DECREF: There's only one definition of this now. Yay! That was that last one in the family defined multiple times in an #ifdef maze. Py_FatalError(): Changed the char* signature to const char*. _Py_NegativeRefcount(): New helper function for the Py_REF_DEBUG expansion of Py_DECREF. Calling an external function cuts down on the volume of generated code. The previous inline expansion of abort() didn't work as intended on Windows (the program often kept going, and the error msg scrolled off the screen unseen). _Py_NegativeRefcount calls Py_FatalError instead, which captures our best knowledge of how to abort effectively across platforms.
* PyNode_AddChild() and fancy_roundup(): Be paranoid about int overflow.Tim Peters2002-07-081-2/+7

* PyNode_AddChild(): Do aggressive over-allocation when the number ofTim Peters2002-07-081-8/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | children gets large, to avoid severe platform realloc() degeneration in extreme cases (like test_longexp). Bugfix candidate. This was doing extremely timid over-allocation, just rounding up to the nearest multiple of 3. Now so long as the number of children is <= 128, it rounds up to a multiple of 4 but via a much faster method. When the number of children exceeds 128, though, and more space is needed, it doubles the capacity. This is aggressive over-allocation. SF patch <http://www.python.org/sf/578297> has Andrew MacIntyre using PyMalloc in the parser to overcome platform malloc problems in test_longexp on OS/2 EMX. Jack Jansen notes there that it didn't help him on the Mac, because the Mac has problems with frequent ever-growing reallocs, not just with gazillions of teensy mallocs. Win98 has no visible problems with test_longexp, but I tried boosting the test-case size and soon got "senseless" MemoryErrors out of it, and soon after crashed the OS: as I've seen in many other contexts before, while the Win98 realloc remains zippy in bad cases, it leads to extreme fragmentation of user address space, to the point that the OS barfs. I don't yet know whether this fixes Jack's Mac problems, but it does cure Win98's problems when boosting the test case size. It also speeds test_longexp in its unaltered state.

| | | | | | | | | | | | | | | | | | | | | | | | | | This introduces: - A new operator // that means floor division (the kind of division where 1/2 is 0). - The "future division" statement ("from __future__ import division) which changes the meaning of the / operator to implement "true division" (where 1/2 is 0.5). - New overloadable operators __truediv__ and __floordiv__. - New slots in the PyNumberMethods struct for true and floor division, new abstract APIs for them, new opcodes, and so on. I emphasize that without the future division statement, the semantics of / will remain unchanged until Python 3.0. Not yet implemented are warnings (default off) when / is used with int or long arguments. This has been on display since 7/31 as SF patch #443474. Flames to /dev/null.

* Add a really stupid warning about 'yield' used as an identifier.Guido van Rossum2001-07-171-0/+12
| | | | | | | | | | | | | | | This is really stupid because it cannot be suppressed or altered using the warning framework; that's because the warning framework is built on Python interpreter internals, and the parser generator doesn't have access to any of those (you cannot use anything of type PyObject * in the parser). But it's better than nothing, and implementing a proper check for this appears to require modifying compile.c in a dozen places, for which I don't have the stamina today. I promise we'll do better in 2.2a2. At least it tells you the filename and line number (unlike the first hack I considered :-).
* Ugly. A pile of new xxxFlags() functions, to communicate to the parserTim Peters2001-07-161-5/+22
| | | | | | | | | | | | | | | | | | | | | | | that 'yield' is a keyword. This doesn't help test_generators at all! I don't know why not. These things do work now (and didn't before this patch): 1. "from __future__ import generators" now works in a native shell. 2. Similarly "python -i xxx.py" now has generators enabled in the shell if xxx.py had them enabled. 3. This program (which was my doctest proxy) works fine: from __future__ import generators source = """\ def f(): yield 1 """ exec compile(source, "", "single") in globals() print type(f())

* Fix a bug in stack overflow error handling. This fixes half of BugGuido van Rossum2000-10-021-1/+1
| | | | | | | | | | | #115555. The error from s_push() on stack overflow was -1, which was passed through unchanged by push(), but not tested for by push()'s caller -- which only expected positive error codes. Fixed by changing s_push() to return E_NOMEM on stack overflow. (Not quite the proper error code either, but I can't be bothered adding a new E_STACKOVERFLOW error code in all the right places.)
