* 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
| | | | | | Call error_ret() in decode_str(). It was called in some other places, but seemed inconsistent. It is safe to call PyTokenizer_Free() after calling error_ret().

* 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.
* - Fix segfault with invalid coding.Neal Norwitz2005-10-023-2/+12
| | | | | | | - SF Bug #772896, unknown encoding results in MemoryError, which is not helpful I will only backport the segfault fix. I'll let Anthony decide if he wants the other changes backported. I will do the backport if asked.

* In a threads-disabled build, typing Ctrl-C into a raw_input() crashed,Michael W. Hudson2005-04-071-0/+4
| | | | | | | | | because (essentially) I didn't realise that PY_BEGIN/END_ALLOW_THREADS actually expanded to nothing under a no-threads build, so if you somehow NULLed out the threadstate (e.g. by calling PyThread_SaveThread) it would stay NULLed when you return to Python. Argh! Backport candidate.
