Guido van Rossum	758eec0172	Rewritten PyImport_Cleanup() and its helper, clear_carefully(). They now implement the following finalization strategy. 1. Whenever this code deletes a module, its directory is cleared carefully, as follows: - set all names to None that begin with exactly one underscore - set all names to None that don't begin with two underscores - clear the directory 2. Modules are deleted in the following order: - modules with a reference count of 1, except __builtin__ or __sys__ - repeat until no more are found with a reference count of 1 - __main__ if it's still there - all remaining modules except __builtin__ or sys - sys _ __builtin__	28 years ago
Guido van Rossum	8f18320270	Last-minute fix for Jim H: don't die after del sys.stdout	29 years ago
Guido van Rossum	aa06b0ede5	Plug the most annoying recursive printing problem -- reset '_' to None before printing and set it to the printed variable after printing (and only when printing is successful).	29 years ago
Guido van Rossum	7d4f68c15f	Oops -- '(' is also a legal start character of a new format...	29 years ago
Guido van Rossum	e8c27bb3ea	Oops! Should've renamed dos_8x3 to dos-8x3 here, too.	29 years ago
Guido van Rossum	330aafb0c2	For base 10, cast unsigned long to long before testing overflow. This prevents 4294967296 from being an acceptable way to spell zero!	29 years ago
Guido van Rossum	d6af46d4ae	Need a cast when comparing type object in isinstance()	29 years ago
Guido van Rossum	231a41e708	Add explicit check for correct next character in format at end of format. This will complain about illegal formats like "O#" instead of ignoring the '#'.	29 years ago
Guido van Rossum	19b55f2d17	Fix subtle bug in cleanup code in PyErr_NormalizeException(), detected by Marc Lemburg. There's a path through the code where *val is NULL, but value isn't, and value should be DECREF'ed.	29 years ago
Guido van Rossum	1707aad27c	Changed the finalization order again so that the reference count printing (when Py_DEBUG is defined) happens while there's still a current thread...	29 years ago
Guido van Rossum	595d7ba069	Jeff Rush: add definition for S_IFMT for VisualAge C/C++ under OS2.	29 years ago
Guido van Rossum	08052c7bb6	Add the flag RTLD_GLOBAL to the dlopen() options. This exports symbols defined by the loaded extension to other extensions (loaded later). (I'm not quite sure about this but suppose it can't hurt...)	29 years ago
Guido van Rossum	c425d2f87b	Make stdin unbuffered too, when PYTHONUNBUFFERED is specified.	29 years ago
Guido van Rossum	f5dd914196	Support type objects in isinstance(). E.g. isinstance('',types.StringType) will return true now instead of raising a TypeError exception. This is for JPython compatibility.	29 years ago
Guido van Rossum	ddc3fb5734	Apply str() to sys.ps1 or sys.ps2 before using them as a prompt, so you can assign an object whose str() evaluates to the current directory (or whatever).	29 years ago
Guido van Rossum	8e9ebfd337	os2 patch by Jeff Rush	29 years ago
Guido van Rossum	db847bd9ea	Plug memory leak in Py_BuildValue when using {...} to construct dictionaries.	29 years ago
Guido van Rossum	2e58ff3ef5	Fix importing of shared libraries from inside packages. This is a bit of a hack: when the shared library is loaded, the module name is "package.module", but the module calls Py_InitModule() with just "module" for the name. The shared library loader squirrels away the true name of the module in _Py_PackageContext, and Py_InitModule() will substitute this (if the name actually matches).	29 years ago
Guido van Rossum	858cb73bb2	Two changes (here we go again :-( ). 1) The __builtins__ variable in the __main__ module is set to the __builtin__ module instead of its __dict__. 2) Get rid of the SIGHUP and SIGTERM handlers. They can't be made to work reliably when threads may be in use, they are Unix specific, and Python programmers can now program this functionality is a safer way using the signal module.	29 years ago
Guido van Rossum	df9db1ea18	Give more detailed error message when the argument count isn't right.	29 years ago
Guido van Rossum	dfed725e2c	Fix memory leak in exec statement with code object -- the None returned by PyEval_EvalCode() on success was never DECREF'ed. Fix by Bernhard Herzog.	29 years ago
Guido van Rossum	4a1f39a26b	Undo half of the previous change :-( Setting interp->builtins to the __builtin__ module instead of to its dictionary had the unfortunate side effect of always running in restricted execution mode :-( I will check in a different way of setting __main__.__builtins__ to the __builtin__ module later. Also, there was a typo -- a comment was unfinished, and as a result some finalizations were not being executed. In Bart Simpson style, I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes. I Will Not Check In Untested Changes.	29 years ago
Guido van Rossum	25c649fdf2	Get rid of another reference to _PyImport_Inittab (now a static array) that should be PyImport_Inittab (a new pointer initialized to point to the array).	29 years ago
Guido van Rossum	22348dc0e1	The warning about thread still having a frame now only happens in verbose mode.	29 years ago
Guido van Rossum	3a44e1b9fb	Two independent changes (alas): - The interp->builtins variable (and hence, __main__.__builtins__) is once again initialized to the built-in module instead of its dictionary. - The finalization order is once again changed. Signals are finalized relatively early, because (1) it DECREF's the signal handlers, and if a signal handler happens to be a bound method, deleting it could cause problems when there's no current thread around, and (2) we don't want to risk executing signal handlers during finalization.	29 years ago
Guido van Rossum	197346fafe	New policy for package imports: only a directory containing __init__.py (or __init__.pyc/.pyo, whichever applies) is considered a package. All other subdirectories are left alone. Should make Konrad Hinsen happy!	29 years ago
Guido van Rossum	771c6c8f7a	Instead of using _PyImport_Inittab[] directly, use the new "official" pointer *PyImport_Inittab which is initialized to _PyImport_Inittab.	29 years ago
Guido van Rossum	e85da651dd	Some patches to Lee Busby's fpectl mods that accidentally didn't make it into 1.5a4.	29 years ago
Guido van Rossum	ed1100f3b6	Don't use sscanf(s, "%x", &c) to parse \xX... escapes; hardcode it.	29 years ago
Guido van Rossum	3b31cd2fe7	Shared libraries didn't quite work under AIX because of the change in status of the GNU readline interface. Here's a patch, by Vladimir Marangozov.	29 years ago
Guido van Rossum	9a61dc90e2	Moved mac-specific speedup to a different place (Jack)	29 years ago
Guido van Rossum	ac1fc95c3c	Fixed for WITHOUT_COMPLEX compilation (Jack)	29 years ago
Guido van Rossum	2ac650f385	New version of PyErr_NewException() that is compatible with -X option.	29 years ago
Guido van Rossum	999e5e921e	Initialize Py_UseClassExceptionsFlag to 1.	29 years ago
Guido van Rossum	a7f2e813c9	Remove unreachable "return 1" at end of ensure_fromlist().	29 years ago
Guido van Rossum	aa9606f45a	Fix small omission: with all the new code, sys.exit(None) would print "None"; this should be equivalent to sys.exit(0).	29 years ago
Guido van Rossum	b74eca9349	Change PyEval_SaveThread() and PyEval_RestoreThread() to always do the tstate swapping. Only the acquiring and releasing of the lock is conditional (twice, under ``#ifdef WITH_THREAD'' and inside ``if (interpreter_lock)'').	29 years ago
Guido van Rossum	b4102bf5f8	Fix a bug in this code that made it do the wrong thing when an option was a single '-'. Thanks to Andrew Kuchling.	29 years ago
Barry Warsaw	3a74993118	PyErr_NormalizeException(): If the exception's type is a class and the instance's class is a subclass of this, then use the instance's class as the exception type.	29 years ago
Guido van Rossum	6c1e5f2033	Get DLL version from a variable.	29 years ago
Guido van Rossum	ee81af8977	Release interpreter lock around readline call in [raw_]input().	29 years ago
Barry Warsaw	963b871e86	Py_Initialize(): move the call to _PyImport_FixupExtension() to after the phase 2 init of the __builtin__ module, so that multiple interpreters will get the right exceptions.	29 years ago
Barry Warsaw	b01a7fa5f8	initerrors(): Eliminate circular reference which was causing a small but annoying memory leak. This was introduced when PyExc_Exception was added; the loop above populating the PyExc_StandardError exception tuple started at index 1 in bltin_exc, but PyExc_Exception was added at index 0, so PyExc_StandardError was getting inserted in itself! How else can a tuple include itself?! Change the loop to start at index 2. This was a fun one! :-)	29 years ago
Barry Warsaw	412cdc2284	[Py_Exc]NumberError => [Py_Exc]ArithmeticError	29 years ago
Barry Warsaw	2f5f6a2595	PyErr_Print(): When printing a class exception, try to dig out the __module__ string and if found, print <module>.<class>, unless <module> == "exceptions".	29 years ago
Guido van Rossum	7617e05a9b	New API PyErr_NewException(name, base, dict) to create simple new exceptions.	29 years ago
Guido van Rossum	0474832d9c	Introduce PyExc_Exception as the conceptual root class for all exceptions.	29 years ago
Guido van Rossum	0207e6de38	Added docstrings. Not for the obsolete functions though.	29 years ago
Guido van Rossum	c172f26861	Deleted find_module_in_package and find_module_in_directory -- they aren't needed and it was a mistake to add them.	29 years ago
Guido van Rossum	a86f77d4dd	Crrected a flow control error that caused the wrong error message when load-module() didn't find a built-in or frozen module. Also got rid of is_frozen(), which duplicated the functionality of find_frozen()!=NULL.	29 years ago
