* #3367: revert rev. 65539: this change causes test_parser to failAndrew M. Kuchling2008-08-051-1/+1

* #3367 from Kristjan Valur Jonsson:Andrew M. Kuchling2008-08-051-1/+1
| | | | | | | If a PyTokenizer_FromString() is called with an empty string, the tokenizer's line_start member never gets initialized. Later, it is compared with the token pointer 'a' in parsetok.c:193 and that behavior can result in undefined behavior.
* This reverts r63675 based on the discussion in this thread:Gregory P. Smith2008-06-091-16/+16
| | | | | | | http://mail.python.org/pipermail/python-dev/2008-June/079988.html Python 2.6 should stick with PyString_* in its codebase. The PyBytes_* names in the spirit of 3.0 are available via a #define only. See the email thread.

* Revert r61969 which added casts to Py_CHARMASK to avoid compiler warnings.Neal Norwitz2008-03-281-8/+0
| | | | | | Rather than sprinkle casts throughout the code, change Py_CHARMASK to always cast it's result to an unsigned char. This should ensure we do the right thing when accessing an array with the result.

* Finished backporting PEP 3127, Integer Literal Support and Syntax.Eric Smith2008-03-171-1/+25

Renamed test_hexoct.py to test_int_literal.py and added binary tests. Added upper and lower case 0b, 0O, and 0X tests to test_int_literal.py

* Patch #1357836:Neal Norwitz2006-06-021-9/+11
| | | | | | | | | | Prevent an invalid memory read from test_coding in case the done flag is set. In that case, the loop isn't entered. I wonder if rather than setting the done flag in the cases before the loop, if they should just exit early. This code looks like it should be refactored. Backport candidate (also the early break above if decoding_fgets fails)

* As discussed on python-dev, really fix the PyMem_*/PyObject_* memory APINeal Norwitz2006-04-111-22/+22
| | | | | | | | | | | | | | | | mismatches. At least I hope this fixes them all. This reverts part of my change from yesterday that converted everything in Parser/*.c to use PyObject_* API. The encoding doesn't really need to use PyMem_*, however, it uses new_string() which must return PyMem_* for handling the result of PyOS_Readline() which returns PyMem_* memory. If there were 2 versions of new_string() one that returned PyMem_* for tokens and one that return PyObject_* for encodings that could also fix this problem. I'm not sure which version would be clearer. This seems to fix both Guido's and Phillip's problems, so it's good enough for now. After this change, it would be good to review Parser/*.c for consistent use of the 2 memory APIs.
* Fix the code in Parser/ to also compile with C++. This was mostly casts forAnthony Baxter2006-04-111-12/+13

* SF patch #1467512, fix double free with triple quoted string in standard build.Neal Norwitz2006-04-101-6/+6
| | | | | | This was the result of inconsistent use of PyMem_* and PyObject_* allocators. By changing to use PyObject_* allocator almost everywhere, this removes the inconsistency.
* Years in the making.Tim Peters2006-03-261-39/+44
| | | | | | | | | | | | | | | | | | | | | | | | objimpl.h, pymem.h: Stop mapping PyMem_{Del, DEL} and PyMem_{Free, FREE} to PyObject_{Free, FREE} in a release build. They're aliases for the system free() now. _subprocess.c/sp_handle_dealloc(): Since the memory was originally obtained via PyObject_NEW, it must be released via PyObject_FREE (or _DEL). pythonrun.c, tokenizer.c, parsermodule.c: I lost count of the number of PyObject vs PyMem mismatches in these -- it's like the specific function called at each site was picked at random, sometimes even with memory obtained via PyMem getting released via PyObject. Changed most to use PyObject uniformly, since the blobs allocated are predictably small in most cases, and obmalloc is generally faster than system mallocs then. If extension modules in real life prove as sloppy as Python's front end, we'll have to revert the objimpl.h + pymem.h part of this patch. Note that no problems will show up in a debug build (all calls still go thru obmalloc then). Problems will show up only in a release build, most likely segfaults.
* Use macro versions instead of function versions when we already know the type.Neal Norwitz2006-03-201-1/+3
| | | | | | | | This will hopefully get rid of some Coverity warnings, be a hint to developers, and be marginally faster. Some asserts were added when the type is currently known, but depends on values from another function.
* Fix crashing bug in tokenizer, when tokenizing files with non-ASCII bytesThomas Wouters2006-03-021-0/+5
| | | | | | | | | | | | | | | | | | | but without a specified encoding: decoding_fgets() (and decoding_feof()) can return NULL and fiddle with the 'tok' struct, making tok->buf NULL. This is okay in the other cases of calls to decoding_*(), it seems, but not in this one. This should get a test added, somewhere, but the testsuite doesn't seem to test encoding anywhere (although plenty of tests use it.) It seems to me that decoding errors in other places in the code (like at the start of a token, instead of in the middle of one) make the code end up adding small integers to NULL pointers, but happen to check for error states before using the calculated new pointers. I haven't been able to trigger any other crashes, in any case. I would nominate this file for a comlete rewrite for Py3k. The whole decoding trick is too bolted-on for my tastes.
