| | | | | | | | | PyTypeObject structures, I had to make prototypes for the functions, and move the structure definition ahead of the functions. I'd dearly like a better way to do this - to change this would make for a massive set of changes to the codebase. There's still some warnings - this is purely to get rid of errors first.

* Um, I thought I'd already checked this in.Guido van Rossum2006-03-101-26/+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.
* Updates to the with-statement:Guido van Rossum2006-02-281-3/+37
| | | | | | | | | | | | | | | | - 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.

* Add a workaround for file.ftell() to raise IOError for ttys.Hye-Shik Chang2005-12-131-0/+7
| | | | | ftell(3) on BSD doesn't set errno even for ttys and returns useless values.
* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-3/+4
| | | | | | | | | | | | | | | | | | | 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 *.
* Disallow opening files with modes 'aU' or 'wU' as specified by PEPSkip Montanaro2005-05-201-0/+51

* If close() fails in file_dealloc, then print an error message toPeter Astrand2004-11-071-1/+8

* If a file is opened with an explicit buffer size >= 1, repeatedAndrew MacIntyre2004-04-041-0/+2
| | | | | | | | close() calls would attempt to free() the buffer already free()ed on the first close(). [bug introduced with patch #788249] Making sure that the buffer is free()ed in file object deallocation is a belt-n-braces bit of insurance against a memory leak.

* SF bug 801631: file.truncate fault on windows.Tim Peters2003-09-071-74/+66
| | | | | | | | | | | | | | | | | file_truncate(): C doesn't define what fflush(fp) does if fp is open for update, and the preceding I/O operation on fp was input. On Windows, fflush() actually changes the current file position then. Because Windows doesn't support ftruncate() directly, this not only caused Python's file.truncate() to change the file position (contra our docs), it also caused the file not to change size. Repaired by getting the initial file position at the start, restoring it at the end, and tossing all the complicated micro-efficiency checks trying to avoid "provably unnecessary" seeks. file.truncate() can't be a frequent operation, and seeking to the current file position has got to be cheap anyway. Bugfix candidate.
