* SF patch #1467512, fix double free with triple quoted string in standard build.Neal Norwitz2006-04-109-37/+45
| | | | | | This was the result of inconsistent use of PyMem_* and PyObject_* allocators. By changing to use PyObject_* allocator almost everywhere, this removes the inconsistency.
* Make path calculation platform independentJeremy Hylton2006-04-041-1/+1

* Add lineno, col_offset to excephandler to enable future fix forJeremy Hylton2006-04-042-3/+6
| | | | | | | | | | | | | | | tracing/line number table in except blocks. Reflow long lines introduced by col_offset changes. Update test_ast to handle new fields in excepthandler. As note in Python.asdl says, we might want to rethink how attributes are handled. Perhaps they should be the same as other fields, with the primary difference being how they are defined for all types within a sum. Also fix asdl_c so that constructors with int fields don't fail when passed a zero value.
* * Fix a refleak of *_attributes.Neal Norwitz2006-04-031-5/+7
| | | | | | * Cleanup formatting a bit (add spaces). * Move static var initialized inside init_types() since that's the only place it's used.
* 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.
* SF #1444030: Fix several potential defects found by Coverity.Hye-Shik Chang2006-03-071-0/+2
| | | | (reviewed by Neal Norwitz)
* 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.

* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | - IMPORT_NAME takes an extra argument from the stack: the relativeness of the import. Only passed to __import__ when it's not -1. - __import__() takes an optional 5th argument for the same thing; it __defaults to -1 (old semantics: try relative, then absolute) - 'from . import name' imports name (be it module or regular attribute) from the current module's *package*. Likewise, 'from .module import name' will import name from a sibling to the current module. - Importing from outside a package is not allowed; 'from . import sys' in a toplevel module will not work, nor will 'from .. import sys' in a (single-level) package. - 'from __future__ import absolute_import' will turn on the new semantics for import and from-import: imports will be absolute, except for from-import with dots. Includes tests for regular imports and importhooks, parser changes and a NEWS item, but no compiler-package changes or documentation changes.

* PEP 343 -- the with-statement.Guido van Rossum2006-02-271-0/+1
| | | | | | | | | | | | | This was started by Mike Bland and completed by Guido (with help from Neal). This still needs a __future__ statement added; Thomas is working on Michael's patch for that aspect. There's a small amount of code cleanup and refactoring in ast.c, compile.c and ceval.c (I fixed the lltrace behavior when EXT_POP is used -- however I had to make lltrace a static global).
* Create _ast module.Martin v. Löwis2006-02-271-191/+86

* PEP 308 implementation, including minor refdocs and some testcases. ItThomas Wouters2006-02-271-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | breaks the parser module, because it adds the if/else construct as well as two new grammar rules for backward compatibility. If no one else fixes parsermodule, I guess I'll go ahead and fix it later this week. The TeX code was checked with texcheck.py, but not rendered. There is actually a slight incompatibility: >>> (x for x in lambda:0) Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: iteration over non-sequence changes into >>> (x for x in lambda: 0) File "<stdin>", line 1 (x for x in lambda: 0) ^ SyntaxError: invalid syntax Since there's no way the former version can be useful, it's probably a bugfix ;)

* Improved handling of syntax errors.Jeremy Hylton2006-01-271-0/+1
| | | | | | | | | | | | | | | | | Expand set of errors caught in set_context(). Some new errors, some old error messages changed for consistency. Fixed error checking in generator expression code. The first set of tests were impossible condition given the grammar. In general, the ast code uses REQ() for those sanity checks. Fix some error handling for augmented assignments. As comments in the code explain, set_context() ought to work here, but I got unexpected crashes when I tried it. Should come back to this. Add note to Grammar that yield expression is a special case. Add doctest cases for SyntaxErrors raised by ast.c.

| | | | | | | comment based on 'sys.args[0]' does not depend on the path. For Python builds from a remote directory ("/path/to/configure; make") the previous logic used to include the "/path/to" portion in Python-ast.h. Then svn would consider this file to be locally modified.
* SF #1373150, diffs in working copy after a buildNeal Norwitz2005-12-111-1/+5
| | | | | | | | Strip off leading dots and slash so the generated files are the same regardless of whether you configure in the checkout directory or build. If anyone configures in a different directory, we might want a cleaner approach using os.path.*(). Hopefully this is good enough.
* Fix some more memory leaks.Neal Norwitz2005-11-161-6/+11

* Merge ast-branch to headJeremy Hylton2005-10-207-4/+1967
| | | | | | | | | | 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.
