* Add some asserts. In sysmodule, I think these were to try to silenceNeal Norwitz2006-10-281-0/+4
| | | | | | | some warnings from Klokwork. They verify the assumptions of the format of svn version output. The assert in the thread module helped debug a problem on HP-UX.
* Forward-port of r52136,52138: a review of overflow-detecting code.Armin Rigo2006-10-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | * unified the way intobject, longobject and mystrtoul handle values around -sys.maxint-1. * in general, trying to entierely avoid overflows in any computation involving signed ints or longs is extremely involved. Fixed a few simple cases where a compiler might be too clever (but that's all guesswork). * more overflow checks against bad data in marshal.c. * 2.5 specific: fixed a number of places that were still confusing int and Py_ssize_t. Some of them could potentially have caused "real-world" breakage. * list.pop(x): fixing overflow issues on x was messy. I just reverted to PyArg_ParseTuple("n"), which does the right thing. (An obscure test was trying to give a Decimal to list.pop()... doesn't make sense any more IMHO) * trying to write a few tests...
* Handle allocation failures gracefully. Found with failmalloc.Neal Norwitz2006-07-211-39/+34
| | | | Many (all?) of these could be backported.
* After approval from Anthony, merge the tim-current_framesTim Peters2006-07-101-0/+17
| | | | | | branch into the trunk. This adds a new sys._current_frames() function, which returns a dict mapping thread id to topmost thread stack frame.
* _PySys_Init(): It's rarely a good idea to size a buffer to theTim Peters2006-06-061-1/+1
| | | | | | | | exact maximum size someone guesses is needed. In this case, if we're really worried about extreme integers, then "cp%d" can actually need 14 bytes (2 for "cp" + 1 for \0 at the end + 11 for -(2**31-1)). So reserve 128 bytes instead -- nothing is actually saved by making a stack-local buffer tiny.
* Add 3 more bytes to a buffer to cover constants in string and null byte on ↵Brett Cannon2006-06-051-1/+1

* Expose Subversion revision number (calculated via "svnversion .") to Python.Barry Warsaw2005-12-181-0/+3
| | | | | | | Add C API function Py_GetBuildNumber(), add it to the interactive prompt banner (i.e. Py_GetBuildInfo()), and add it as the sys.build_number attribute. The build number is a string instead of an int because it may contain a trailing 'M' if there are local modifications.
* Merge ast-branch to headJeremy Hylton2005-10-201-1/+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.

* Small function call optimization and special build option for call stats.Jeremy Hylton2003-02-051-2/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | -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.
* Patch #664376: sys.path[0] should contain absolute pathname.Thomas Heller2003-01-081-0/+12
| | | | | | | | This fixes the problem on Windows - that's the only system where I can test it. It leaves sys.argv alone and only changes sys.path[0] to an absolute pathname.
* Add os.path.supports_unicode_filenames for all platforms,Mark Hammond2002-10-081-0/+37
| | | | | | sys.getwindowsversion() on Windows (new enahanced Tim-proof <wink> version), and fix test_pep277.py in a few minor ways. Including doc and NEWS entries.

| | | | | | | | | | globals, _Py_Ticker and _Py_CheckInterval. This also implements Jeremy's shortcut in Py_AddPendingCall that zeroes out _Py_Ticker. This allows the test in the main loop to only test a single value. The gory details are at http://python.org/sf/602191

Took a light stab at repairing comments that are no longer true. sys_gettotalrefcount(): Changed to enable under Py_REF_DEBUG. It was enabled under Py_TRACE_REFS, which was much heavier than necessary. sys.gettotalrefcount() is now available in a Py_REF_DEBUG-only build.
