* 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.

* Implement PEP 238 in its (almost) full glory.Guido van Rossum2001-08-081-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | 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())
* Preliminary support for "from __future__ import generators" to enableGuido van Rossum2001-07-152-3/+36

* 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.)
* More limits.h stuff in node.c.Tim Peters2000-09-261-9/+1
| | | | Fred, check this!
* Rationalize use of limits.h, moving the inclusion to Python.h.Fred Drake2000-09-261-3/+0
| | | | | | | | Add definitions of INT_MAX and LONG_MAX to pyport.h. Remove includes of limits.h and conditional definitions of INT_MAX and LONG_MAX elsewhere. This closes SourceForge patch #101659 and bug #115323.
* Move down the INT_MAX logic, because HAVE_LIMITS_H was always undefinedVladimir Marangozov2000-09-031-6/+6
| | | | | | and this breaks the AIX build with an INT_MAX redefinition error. "config.h" is included in pgenheaders.h, so moving this down fixes the problem.

* Charles G. Waldman <cgw@fnal.gov>:Fred Drake2000-08-241-1/+6
| | | | | | | | | Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit arguments to opcodes instead of being forced to stick to the 16-bit limit. This is especially useful for machine-generated code, which can be too long for the SET_LINENO parameter to fit into 16 bits. This closes the implementation portion of SourceForge patch #100893.

* Recent ANSIfication introduced a couple instances ofTim Peters2000-07-231-3/+1
| | | | | | | | | | | #if RETSIGTYPE != void That isn't C, and MSVC properly refuses to compile it. Introduced new Py_RETURN_FROM_SIGNAL_HANDLER macro in pyport.h to expand to the correct thing based on RETSIGTYPE. However, only void is ANSI! Do we still have platforms that return int? The Unix config mess appears to #define RETSIGTYPE by magic without being asked to, so I assume it's "a problem" across Unices still.
* Remember to return something if RETSIGTYPE is not 'void'. Do we still needThomas Wouters2000-07-221-0/+3

* Mass ANSIfication.Thomas Wouters2000-07-2216-330/+123

There is a minor style issue involved: Guido seems to have preferred English grammar (behaviour, honour) in a couple places. This patch changes that to American, which is the more prominent style in the source. I prefer English myself, so if English is preferred, I'd be happy to supply a patch myself ;)
