* Bug #1520864 (again): unpacking singleton tuples in list comprehensions andNeal Norwitz2006-09-051-1/+2
| | | | | | | | | | | | | generator expressions (x for x, in ... ) works again. Sigh, I only fixed for loops the first time, not list comps and genexprs too. I couldn't find any more unpacking cases where there is a similar bug lurking. This code should be refactored to eliminate the duplication. I'm sure the listcomp/genexpr code can be refactored. I'm not sure if the for loop can re-use any of the same code though. Will backport to 2.5 (the only place it matters).

* Bug #1191458: tracing over for loops now produces a line eventNeal Norwitz2006-08-041-1/+2
| | | | | | | | | | | | on each iteration. I'm not positive this is the best way to handle this. I'm also not sure that there aren't other cases where the lnotab is generated incorrectly. It would be great if people that use pdb or tracing could test heavily. Also: * Remove dead/duplicated code that wasn't used/necessary because we already handled the docstring prior to entering the loop. * add some debugging code into the compiler (#if 0'd out).
* Patch #1531113: Fix augmented assignment with yield expressions.Neal Norwitz2006-07-301-2/+3

| | | | | | | | | | valid and invalid file paths for the built-in import machinery which leads to fewer open calls on startup. Also fix issue with PEP 302 style import hooks which lead to more open() calls than necessary.
* Replace PyObject_CallFunction calls with only object argsGeorg Brandl2006-05-251-3/+3
| | | | with PyObject_CallFunctionObjArgs, which is 30% faster.
* - Add new Warning class, ImportWarningThomas Wouters2006-04-271-7/+30
| | | | | | | | | | | | | | - Warn-raise ImportWarning when importing would have picked up a directory as package, if only it'd had an __init__.py. This swaps two tests (for case-ness and __init__-ness), but case-test is not really more expensive, and it's not in a speed-critical section. - Test for the new warning by importing a common non-package directory on sys.path: site-packages - In regrtest.py, silence warnings generated by the build-environment because Modules/ (which is added to sys.path for Setup-created modules) has 'zlib' and '_ctypes' directories without __init__.py's.
* spread the extern "C" { } magic pixie dust around. Python itself builds nowAnthony Baxter2006-04-131-0/+7
| | | | | using a C++ compiler. Still lots and lots of errors in the modules built by setup.py, and a bunch of warnings from g++ in the core.
* Fix refleak in __import__("") (probably the cause of the 2 refleaks inThomas Wouters2006-04-051-0/+2

* Fix __import__("") to raise ValueError rather than return None.Thomas Wouters2006-04-041-1/+10

* Use macro versions instead of function versions when we already know the type.Neal Norwitz2006-03-201-2/+2
| | | | | | | | 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.
* Um, I thought I'd already checked this in.Guido van Rossum2006-03-101-0/+1
| | | | | | | Anyway, this is the changes to the with-statement so that __exit__ must return a true value in order for a pending exception to be ignored. The PEP (343) is already updated.
* Change int to Py_ssize_t in several places.Martin v. Löwis2006-03-071-4/+4
| | | | | Add (int) casts to silence compiler warnings. Raise Python exceptions for overflows.
* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-281-13/+56
| | | | | | | | | | | | | | | | | | | | | | | - 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 Rossum2006-02-271-1/+2
| | | | | | | | | | | | | 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).

* Check return result from Py_InitModule*(). This API can fail.Neal Norwitz2006-01-191-0/+2
| | | | Probably should be backported.
* Merge from ast-arena. This reduces the code in Python/ast.c by ~300 lines,Neal Norwitz2005-12-171-3/+5
| | | | simplifies a lot of error handling code, and fixes many memory leaks.
* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-2/+2
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.
* the ast-branch changed the stack discipline of MAKE_CLOSURE, so we need toMichael W. Hudson2005-10-211-1/+3
| | | | bump MAGIC.
* Merge ast-branch to headJeremy Hylton2005-10-201-11/+12
| | | | | | | | | | 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 SF bug #976608, Unhelpful error message when mtime of a module is -1Neal Norwitz2005-10-031-1/+5

* This is my patch:Michael W. Hudson2005-06-031-1/+2
| | | | | | | | | [ 1180995 ] binary formats for marshalling floats Adds 2 new type codes for marshal (binary floats and binary complexes), a new marshal version (2), updates MAGIC and fiddles the de-serializing of code objects to be less likely to clobber the real reason for failing if it fails.
* Patch #1197318: Cygwin case-sensitive import patchJason Tishler2005-05-201-17/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | A problem regarding importing symlinked modules was recently reported on the Cygwin mailing list: http://cygwin.com/ml/cygwin/2005-04/msg00257.html The following test case demonstrates the problem: $ ls -l total 1 lrwxrwxrwx 1 jt None 6 Apr 23 13:32 bar.py -> foo.py -rw-r--r-- 1 jt None 24 Apr 18 20:13 foo.py $ python -c 'import bar' Traceback (most recent call last): File "<string>", line 1, in ? ImportError: No module named bar Since Cygwin's case_ok() uses a modified version of the Windows's version, the symlinked bar module actually resolves to file foo.py instead of bar.py. This obviously causes the matching code to fail (regardless of case). The patch fixes this problem by making Cygwin use the Mac OS X case_ok() instead of a modified Window's version.

* SF Patch #1013667: Cleanup Peepholer OutputRaymond Hettinger2004-08-231-1/+2
| | | | | | | | | * Make a pass to eliminate NOPs. Produce code that is more readable, more compact, and a tiny bit faster. Makes the peepholer more flexible in the scope of allowable transformations. * With Guido's okay, bumped up the magic number so that this patch gets widely exercised before the alpha goes out.
* PyImport_ExecCodeModuleEx(): remove module from sys.modules in error cases.Tim Peters2004-08-021-16/+46
| | | | | | | | PyImport_ReloadModule(): restore the module to sys.modules in error cases. load_package(): semantic-neutral refactoring from an earlier stab at this patch; giving it a common error exit made the code easier to follow, so retaining that part. _RemoveModule(): new little utility to delete a key from sys.modules.
