* Generally inehrit codeflags that are in PyCF_MASK, instead of writing it outThomas Wouters2006-02-281-4/+4
| | | | | in multiple places. This makes compile()/eval()/etc also inherit the absolute-import codeflag, like division and with-statement already were.

* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-289-55/+180
| | | | | | | | | | | | | | | | | | | | | | | - 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.

* Check the return code for PyErr_Warn() when warning about raising stringBrett Cannon2006-02-271-4/+5
| | | | | exceptions. This was triggered when 'warnings' had a filter set to "error" that caught the string exception deprecation warning.
* PyErr_ProgramText(): Grrrrrr.Tim Peters2006-02-271-1/+1
| | | | | | | | | | | In a Windows debug build, trying to open a file using an empty string as the name causes assertion death inside MS's C runtime code. We probably need to worm around that in many places. I'm worming around it here to stop the new test_with.py from assert-dying in the Windows debug build (it calls compile() with an empty string for "the file name", which indirectly leads to C-level code in Python trying to fopen("", "r")).

* PEP 343 -- the with-statement.Guido van Rossum2006-02-277-628/+981
| | | | | | | | | | | | | 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).
* Fix parsing of subscriptlist.Jeremy Hylton2006-02-271-4/+30

* Patch 1413181, by Gabriel Becedillas.Tim Peters2006-02-271-0/+4
| | | | | | | | | PyThreadState_Delete(): if the auto-GIL-state machinery knows about the thread state, forget it (since the thread state is being deleted, continuing to remember it can't help, but can hurt if another thread happens to get created with the same thread id). I'll backport to 2.4 next.

| | | | | | | | | | | | | | | | | | | | | | | | | 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 Hylton2006-01-271-35/+74
| | | | | | | | | | | | | | | | | 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.

| | | | | | | Squash new warnings from VC 7.1 about mixing signed and unsigned types in comparisons. I can see why `len` was changed to size_t here, but don't see why `i` was also changed. Change `i` back to int.
* analyze_cells(): This no longer compiled under VC 7.1.Tim Peters2006-01-081-1/+2
| | | | Move declaration of local `flags` to top of block.
