* Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines,Neal Norwitz2005-12-171-0/+1
| | | | simplifies a lot of error handling code, and fixes many memory leaks.
* Merge ast-branch to headJeremy Hylton2005-10-201-2/+1
| | | | | | | | | | 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.

| | | | | | | | | | | | | | | | This gets compilation of posixmodule.c to succeed on Tru64 and does no harm on Linux. We may need to undefine it on some platforms, but let's wait and see.

* Patch #555929: Cygwin AH_BOTTOM cleanup patch (*** version 2 ***)Jason Tishler2002-06-041-8/+8
| | | | | | | | | | | | This patch complies with the following request found near the top of configure.in: # This is for stuff that absolutely must end up in pyconfig.h. # Please use pyport.h instead, if possible. I tested this patch under Cygwin, Win32, and Red Hat Linux. Python built and ran successfully on each of these platforms.

* - New builtin function enumerate(x), from PEP 279. Example:Guido van Rossum2002-04-261-0/+1
| | | | | enumerate("abc") is an iterator returning (0,"a"), (1,"b"), (2,"c"). The argument can be an arbitrary iterable object.
* Add the 'bool' type and its values 'False' and 'True', as described inGuido van Rossum2002-04-031-0/+1
| | | | | | | | | | | | | PEP 285. Everything described in the PEP is here, and there is even some documentation. I had to fix 12 unit tests; all but one of these were printing Boolean outcomes that changed from 0/1 to False/True. (The exception is test_unicode.py, which did a type(x) == type(y) style comparison. I could've fixed that with a single line using issubtype(x, type(y)), but instead chose to be explicit about those places where a bool is expected. Still to do: perhaps more documentation; change standard library modules to return False/True from predicates.

* Give Python a debug-mode pymalloc, much as sketched on Python-Dev.Tim Peters2002-03-231-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When WITH_PYMALLOC is defined, define PYMALLOC_DEBUG to enable the debug allocator. This can be done independent of build type (release or debug). A debug build automatically defines PYMALLOC_DEBUG when pymalloc is enabled. It's a detected error to define PYMALLOC_DEBUG when pymalloc isn't enabled. Two debugging entry points defined only under PYMALLOC_DEBUG: + _PyMalloc_DebugCheckAddress(const void *p) can be used (e.g., from gdb) to sanity-check a memory block obtained from pymalloc. It sprays info to stderr (see next) and dies via Py_FatalError if the block is detectably damaged. + _PyMalloc_DebugDumpAddress(const void *p) can be used to spray info about a debug memory block to stderr. A tiny start at implementing "API family" checks isn't good for anything yet. _PyMalloc_DebugRealloc() has been optimized to do little when the new size is <= old size. However, if the new size is larger, it really can't call the underlying realloc() routine without either violating its contract, or knowing something non-trivial about how the underlying realloc() works. A memcpy is always done in this case. This was a disaster for (and only) one of the std tests: test_bufio creates single text file lines up to a million characters long. On Windows, fileobject.c's get_line() uses the horridly funky getline_via_fgets(), which keeps growing and growing a string object hoping to find a newline. It grew the string object 1000 bytes each time, so for a million-character string it took approximately forever (I gave up after a few minutes). So, also: fileobject.c, getline_via_fgets(): When a single line is outrageously long, grow the string object at a mildly exponential rate, instead of just 1000 bytes at a time. That's enough so that a debug-build test_bufio finishes in about 5 seconds on my Win98SE box. I'm curious to try this on Win2K, because it has very different memory behavior than Win9X, and test_bufio always took a factor of 10 longer to complete on Win2K. It *could* be that the endless reallocs were simply killing it on Win2K even in the release build.
* Include <unistd.h> in Python.h. Fixes #500924.Martin v. Löwis2002-01-121-0/+3

* Stop defining NDEBUG in Python.h, because it can interfere withTim Peters2001-12-041-5/+4

* Part way to allowing "from __future__ import generators" to communicateTim Peters2001-07-161-1/+1
| | | | | | | | | | that info to code dynamically compiled *by* code compiled with generators enabled. Doesn't yet work because there's still no way to tell the parser that "yield" is OK (unlike nested_scopes, the parser has its fingers in this too). Replaced PyEval_GetNestedScopes by a more-general PyEval_MergeCompilerFlags. Perhaps I should not have? I doubted it was *intended* to be part of the public API, so just did.
* Python.h: Don't attempt to redefine NDEBUG if it's already defined.Tim Peters2001-07-151-0/+2

* PEP 227 implementationJeremy Hylton2001-01-251-0/+1
| | | | | | A cell contains a reference to a single PyObject. It could be implemented as a mutable, one-element sequence, but the separate type has less overhead.
* Rationalize use of limits.h, moving the inclusion to Python.h.Fred Drake2000-09-261-0/+4
| | | | | | | | 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.
* Make better use of GNU Pth -- patch by Andy Dustman.Guido van Rossum2000-09-191-1/+1
| | | | | | | | | | | | | | | I can't test this, so I'm just checking it in with blind faith in Andy. I've tested that it doesn't broeak a non-Pth build on Linux. Changes include: - There's a --with-pth configure option. - Instead of _GNU_PTH, we test for HAVE_PTH. - Better signal handling. - (The config.h.in file is regenerated in a slightly different order.)
* Close SF bug 110826: a complaint about the way Python #define'd NULL.Tim Peters2000-09-101-0/+4
| | | | | | | | | | | | | | | It's hard to sort out what the bug was, exactly. So, Big Hammer: 1. Python shouldn't be in the business of #define'ing NULL, period. 2. Users of the Python C API shouldn't be in the business of not including Python.h, period. Hence: 1. Removed all #define's of NULL in Python source code (pyport.h and object.h). 2. Since we're *relying* on stdio.h defining NULL, put an #error in Python.h after its #include of stdio.h if NULL isn't defined then.

| | | | | | | | good C practice hasn't been available to everything all along. Added Py_SAFE_DOWNCAST(VALUE, WIDE, NARROW) macro to pyport.h; this just casts VALUE from type WIDE to type NARROW, but assert-fails if Py_DEBUG is defined and info is lost due to casting. Replaced a line in Fredrik's fix to marshal.c to use the new macro.

* Cray J90 fixes for long ints.Tim Peters2000-07-081-0/+1
| | | | | | | | | | | | | | | | This was a convenient excuse to create the pyport.h file recently discussed! Please use new Py_ARITHMETIC_RIGHT_SHIFT when right-shifting a signed int and you *need* sign-extension. This is #define'd in pyport.h, keying off new config symbol SIGNED_RIGHT_SHIFT_ZERO_FILLS. If you're running on a platform that needs that symbol #define'd, the std tests never would have worked for you (in particular, at least test_long would have failed). The autoconfig stuff got added to Python after my Unix days, so I don't know how that works. Would someone please look into doing & testing an auto-config of the SIGNED_RIGHT_SHIFT_ZERO_FILLS symbol? It needs to be defined if & only if, e.g., (-1) >> 3 is not -1.
