* Um, I thought I'd already checked this in.Guido van Rossum2006-03-101-22/+25
| | | | | | | 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.
* Checking in the code for PEP 357.Guido van Rossum2006-03-071-46/+22
| | | | | | This was mostly written by Travis Oliphant. I've inspected it all; Neal Norwitz and MvL have also looked at it (in an earlier incarnation).

| | | | | | | | | added message attribute compared to the previous version of Exception. It is also a new-style class, making all exceptions now new-style. KeyboardInterrupt and SystemExit inherit from BaseException directly. String exceptions now raise DeprecationWarning. Applies patch 1104669, and closes bugs 1012952 and 518846.
* Updates to the with-statement:Guido van Rossum2006-02-281-6/+20
| | | | | | | | | | | | | | | | - New semantics for __exit__() -- it must re-raise the exception if type is not None; the with-statement itself doesn't do this. (See the updated PEP for motivation.) - Added context managers to: - file - thread.LockType - threading.{Lock,RLock,Condition,Semaphore,BoundedSemaphore} - decimal.Context - Added contextlib.py, which defines @contextmanager, nested(), closing(). - Unit tests all around; bot no docs yet.
* SF patch #1438387, PEP 328: relative and absolute imports.Thomas Wouters2006-02-281-6/+17
| | | | | | | | | | | | | | | | | | | | | | | - 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

* PEP 343 -- the with-statement.Guido van Rossum2006-02-271-7/+42
| | | | | | | | | | | | | 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).

* 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 *.

* Merge ast-branch to headJeremy Hylton2005-10-201-30/+15
| | | | | | | | | | 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.

* SF bug #1014215: Unspecific errors with metaclassRaymond Hettinger2004-09-161-4/+16
| | | | | | | | | | | | | | High level error message was stomping useful detailed messages from lower level routines. The new approach is to augment string error messages returned by the low level routines. The provides both high and low level information. If the exception value is not a string, no changes are made. To see the improved messages in action, type: import random class R(random): pass class B(bool): pass

* This was quite a dark bug in my recent in-place string concatenationArmin Rigo2004-08-071-1/+1

* This closes patch:Michael W. Hudson2004-07-071-1/+1
| | | | | | | | | | | | | | | | | [ 960406 ] unblock signals in threads although the changes do not correspond exactly to any patch attached to that report. Non-main threads no longer have all signals masked. A different interface to readline is used. The handling of signals inside calls to PyOS_Readline is now rather different. These changes are all a bit scary! Review and cross-platform testing much appreciated.
* SF Bug #215126: Over restricted type checking on eval() functionRaymond Hettinger2004-07-021-4/+16
| | | | | | The builtin eval() function now accepts any mapping for the locals argument. Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing down the normal case. My timings so no measurable impact.
