* Several changes that Python carry on in the face of errors in theBarry Warsaw1998-09-141-26/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | initialization of class exceptions. Specifically: init_class_exc(): This function now returns an integer status of the class exception initialization. No fatal errors in this method now. Also, use PySys_WriteStderr() when writing error messages. When an error occurs in this function, 0 is returned, but the partial creation of the exception classes is not undone (this happens elsewhere). Things that could trigger the fallback: - exceptions.py fails to be imported (due to syntax error, etc.) - one of the exception classes is missing (e.g. due to library version mismatch) - exception class can't be inserted into __builtin__'s dictionary - MemoryError instance can't be pre-allocated - some other PyErr_Occurred newstdexception(): Changed the error message. This is still a fatal error because if the string based exceptions can't be created, we really can't continue. initerrors(): Be sure to xdecref the .exc field, which might be non-NULL if class exceptions init was aborted. _PyBuiltin_Init_2(): If class exception init fails, print a warning message and reinstate the string based exceptions.
* Mac-specific mod to enable aliases on import paths.Guido van Rossum1998-09-142-9/+35

* Apparently on AIX when using gcc you need to call pthread_init()Guido van Rossum1998-09-101-0/+3
| | | | | (which is not a POSIX threads call!). Reported and confirmed by Brad Howes.
* Correct typo in #ifdef: PY_THREAD_D4, should be PY_PTHREAD_D4.Guido van Rossum1998-09-041-1/+1
| | | | Reported by Jonathan Giddy.
* Should no longer surround PyOS_Readline() call withGuido van Rossum1998-09-031-4/+0
| | | | | Py_{BEGIN,END}_ALLOW_THREADS macros. Also get rid of the declaration for it (it's now in pythonrun.h).
* Add a 'volatile' to the declaration of threadid in get_thread_ident().Guido van Rossum1998-08-271-1/+1
| | | | | According to Vladimir Marangozov, this is necessary for AIX, where high optimization levels inline this function and then get it wrong :-(
* Don't release the interpreter lock around PyParser_ParseFile().Guido van Rossum1998-08-271-4/+0
| | | | It is needed so that tokenizer.c can use PySys_WriteStderr().
* __file__ used to be always set to the .pyc (or .pyo) file, even ifGuido van Rossum1998-08-251-1/+2
| | | | | | | that file in fact did not exist or at least was not used. Change this so that __file__ is *only* set to the .pyc/.pyo file when it actually read the code object from it; otherwise __file__ is set to the .py file.
* Comment out the print statement about underflow. (This only seems toGuido van Rossum1998-08-251-2/+2
| | | | | | | | happen when you use a non-keyword argument after a keyword argument, and in this case you also get a syntax error. I fully suspect that the underflow is caused by the code that stops generating code when it detects the syntax error, but I can't find the culprit right now. I know, I know.)
* Add the type of the object to the error message about calling a non-function.Guido van Rossum1998-08-251-3/+5

* Restructure the file so that it is never empty. No longer needsGuido van Rossum1998-08-251-10/+10
| | | | Metrowerks specific #ifdef.
* Patch by Mark Hammond to support 64-bit ints on MS platforms.Guido van Rossum1998-08-252-7/+7
| | | | | | The MS compiler doesn't call it 'long long', it uses __int64, so a new #define, LONG_LONG, has been added and all occurrences of 'long long' are replaced with it.
* Ted Horst writes in psa-members@python.org:Guido van Rossum1998-08-241-0/+41
| | | | | | This is a patch that Bill Bummgarner did for 1.4 that hasn't made its way into the distribution yet. This is important if you want to use the ObjC module.
* Add DebugBreak() call to Py_FatalError() for Mark Hammond (only onGuido van Rossum1998-08-131-0/+3
| | | | Win32 in Debug mode).
* Patch by Just van Rossum that changes how we search for submodules ofGuido van Rossum1998-08-111-19/+20
| | | | | | | frozen packages. (I *think* this means that we can now have a built-in module bar that's a submodule of a frozen package foo, by registering the built-in module with a name "foo.bar" in the table of builtin modules.)

* PyErr_SetFromErrnoWithFilename(): New function which supports settingBarry Warsaw1998-07-231-2/+14
| | | | | | | | | | | an exception from errno, with a supplied filename (primarily used by IOError and OSError). If class exceptions are used then the exception is instantiated with a 3-tuple: (errno, strerror, filename). For backwards compatibility reasons, if string exceptions are used, filename is ignored. PyErr_SetFromErrno(): Implement in terms of PyErr_SetFromErrnoWithFilename().
* Added support for two new standard errors: EnvironmentError andBarry Warsaw1998-07-231-5/+16
| | | | | | | | | OSError. The EnvironmentError serves primarily as the (common implementation) base class for IOError and OSError. OSError is used by posixmodule.c Also added tuple definition of EnvironmentError when using string based exceptions.
* Small changes to map() and filter():Guido van Rossum1998-07-101-5/+8
| | | | | | | (1) If a sequence S is shorter than len(S) indicated, don't fail -- just use the shorter size. (I.e, len(S) is just a hint.) (2) Implement the special case map(None, S) as list(S) -- it's faster.
* # In case BINARY_SUBSCR, use proper PyList_GET* macros instead of inlining.Guido van Rossum1998-07-081-3/+3

* Marc-Andre Lemburg's patch to support instance methods with otherGuido van Rossum1998-07-081-0/+5

* Reindented some OS/2 and hpux code that looked ugly or at leastGuido van Rossum1998-07-081-29/+28

* Two error messages still used the old name of the functio mkvalue() --Guido van Rossum1998-07-071-2/+2

* Sigh. The hack to enable special treatment for errno on SGI machinesGuido van Rossum1998-07-071-0/+4
| | | | | | | | | must be enabled here, otherwise the errno we set on overflows is not the errno that's being read by compile.c. Wonder how many other files that do their own "#include config.h" need this too :-( (Because of the structure of autoconf, it's not so simple to get this into config.h...)
* Fix two smal memory leaks discovered by Vadim Chugunov.Guido van Rossum1998-07-011-3/+2

* Fix a stupid little bug: len() of an unsized returns -1 and leaves anGuido van Rossum1998-06-291-1/+5

* Windows-specific hack to make sure that when LoadLibrary() is called,Guido van Rossum1998-06-271-0/+22
| | | | | | the filename contains at least a rudimentary pathname. (The bad part is that we need to call getcwd() because only a prefix of ".\\" is not enough -- we prefix the drive letter.)
* Added doc strings. Maybe the doc string for the module itself is a bitGuido van Rossum1998-06-271-7/+102
| | | | long, but it sure helps!
* Added doc strings.Guido van Rossum1998-06-261-52/+432

* In raw_input(prompt), make sure that str(prompt) really a stringGuido van Rossum1998-06-261-0/+2

* Ignore Windows case check for ALL CAPS 8.3 filesGuido van Rossum1998-06-241-1/+39
|
* When unmarshalling, add test for negative lengths on strings, tuplesGuido van Rossum1998-06-081-2/+14
| | | | | | and lists; if the size is negative, raise an exception. Also raise an exception when an undefined type is found -- all this to increase the chance that garbage input causes an exception instead of a core dump.
* Remove a few unused locals (I love VC++ for this!).Guido van Rossum1998-05-291-2/+0
|
* Moved cmp_member() to abstract.c, as PySequence_Contains() [withGuido van Rossum1998-05-221-53/+2
| | | | | | | | swapped arguments]. Also make sure that no use of a function pointer gotten from a tp_as_sequence or tp_as_mapping structure is made without checking it for NULL first.
* A bunch of functions are now properly implemented in abstract.c, andGuido van Rossum1998-05-221-356/+40
| | | | | | | | | | | the code here becomes much simpler. In particular: abs(), divmod(), pow(), int(), long(), float(), len(), tuple(), list(). Also make sure that no use of a function pointer gotten from a tp_as_sequence or tp_as_mapping structure is made without checking it for NULL first. A few other cosmetic things, such as properly reindenting slice().
* Trivial little change: when setting a member to an object, hold theGuido van Rossum1998-05-201-1/+3
| | | | | | | old value in a temporary and XDECREF it only after then new value has been set. This prevents the (unlikely) case where the destructor of the member uses the containing object -- it would find it in an undefined state.
* Fix a curious bug: statements like "import sys.time" would succeed,Guido van Rossum1998-05-191-3/+10
| | | | | | because the path through the code would notice that sys.__path__ did not exist and it would fall back to the default path (builtins + sys.path) instead of failing). No longer.
* Remove use of RTLD_GLOBAL.Guido van Rossum1998-05-181-6/+4

* Another veeeeeery old patch...Guido van Rossum1998-05-151-9/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Date: Thu, 14 Sep 1995 12:18:20 -0400 From: Alan Morse <alan@dvcorp.com> To: python-list@cwi.nl Subject: getargs bug in 1.2 and 1.3 BETA We have found a bug in the part of the getargs code that we added and submitted, and which was incorporated into 1.1. The parsing of "O?" format specifiers is not handled correctly; there is no "else" for the "if" and therefore it can never fail. What's worse, the advancing of the varargs pointer is not handled properly, so from then on it is out of sync, wreaking all sorts of havoc. (If it had failed properly, then the out-of-sync varargs would not have been an issue.) Below is the context diff for the change. Note that I have made a few stylistic changes beyond adding the else case, namely: 1) Making the "O" case follow the convention established by the other format specifiers of getting all their vararg arguments before performing the test, rather than getting some before and some after the test passes. 2) Making the logic of the tests parallel, so the "if" part indicates that the format is accepted and the "else" part indicates that the format has failed. They were inconsistent with each other and with the the other format specifiers. -Alan Morse (amorse@dvcorp.com)

When the malloc() or realloc() call fails, -1 is returned and the existing table is unchanged.
