* Support type objects in isinstance().Guido van Rossum1997-12-021-10/+15
| | | | | E.g. isinstance('',types.StringType) will return true now instead of raising a TypeError exception. This is for JPython compatibility.
* Apply str() to sys.ps1 or sys.ps2 before using them as a prompt, soGuido van Rossum1997-11-251-16/+14
| | | | | you can assign an object whose str() evaluates to the current directory (or whatever).

|
* Fix importing of shared libraries from inside packages.Guido van Rossum1997-11-192-3/+26
| | | | | | | | 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).
* Two changes (here we go again :-( ).Guido van Rossum1997-11-191-35/+3
| | | | | | | | | | 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.

* Undo half of the previous change :-(Guido van Rossum1997-11-041-7/+6
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Get rid of another reference to _PyImport_Inittab (now a static array)Guido van Rossum1997-11-041-2/+2

* Two independent changes (alas):Guido van Rossum1997-11-031-19/+16
| | | | | | | | | | | | - 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.
* New policy for package imports: only a directory containingGuido van Rossum1997-10-311-2/+38
| | | | | | __init__.py (or __init__.pyc/.pyo, whichever applies) is considered a package. All other subdirectories are left alone. Should make Konrad Hinsen happy!

* initerrors(): Eliminate circular reference which was causing a smallBarry Warsaw1997-09-181-3/+3
| | | | | | | | | | | | 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! :-)

* Crrected a flow control error that caused the wrong error message whenGuido van Rossum1997-09-091-22/+6
| | | | | | 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.

* Significant speedup -- when a submodule imports a global module, add aGuido van Rossum1997-09-061-5/+20
| | | | | | | | | | | | | | | | | | dummy entry to sys.modules, marking the absence of a submodule by the same name. Thus, if module foo.bar executes the statement "import time", sys.modules['foo.time'] will be set to None, once the absence of a module foo.time is confirmed (by looking for it in foo's path). The next time when foo.bar (or any other submodule of foo) executes "import time", no I/O is necessary to determine that there is no module foo.time. (Justification: It may seem strange to pollute sys.modules. However, since we're doing the lookup anyway it's definitely the fastest solution. This is the same convention that 'ni' uses and I haven't heard any complaints.)

* Phase two of package import. "import a.b.c" and all variants now do theGuido van Rossum1997-09-061-17/+299
| | | | | | | | | | | | | | | right thing. Still to do: - Make reload() of a submodule work. - Performance tweaks -- currently, a submodule that tries to import a global module *always* searches the package directory first, even if the global module was already imported. Not sure how to solve this one; probably need to record misses per package. - Documentation!
* Fixed some details of printing the str() of an exception. This fixesGuido van Rossum1997-09-051-2/+6
| | | | | a core dump when __str__() returns a non-string, and plugs a memory leak as well: the result of PyObject_Str() was never DECREFed.
* First part of package support.Guido van Rossum1997-09-055-148/+460
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This doesn't yet support "import a.b.c" or "from a.b.c import x", but it does recognize directories. When importing a directory, it initializes __path__ to a list containing the directory name, and loads the __init__ module if found. The (internal) find_module() and load_module() functions are restructured so that they both also handle built-in and frozen modules and Mac resources (and directories of course). The imp module's find_module() and (new) load_module() also have this functionality. Moreover, imp unconditionally defines constants for all module types, and has two more new functions: find_module_in_package() and find_module_in_directory(). There's also a new API function, PyImport_ImportModuleEx(), which takes all four __import__ arguments (name, globals, locals, fromlist). The last three may be NULL. This is currently the same as PyImport_ImportModule() but in the future it will be able to do relative dotted-path imports. Other changes: - bltinmodule.c: in __import__, call PyImport_ImportModuleEx(). - ceval.c: always pass the fromlist to __import__, even if it is a C function, so PyImport_ImportModuleEx() is useful. - getmtime.c: the function has a second argument, the FILE*, on which it applies fstat(). According to Sjoerd this is much faster. The first (pathname) argument is ignored, but remains for backward compatibility (so the Mac version still works without changes). By cleverly combining the new imp functionality, the full support for dotted names in Python (mini.py, not checked in) is now about 7K, lavishly commented (vs. 14K for ni plus 11K for ihooks, also lavishly commented). Good night!
* Inline PyObject_CallObject (Marc-Andre Lemburg).Guido van Rossum1997-08-301-0/+5
|
* Two independent changes (oops):Guido van Rossum1997-08-291-4/+35
| | | | | | | | | - Changed semantics for initialized flag (again); forget the ref counting, forget the fatal errors -- redundant calls to Py_Initialize() or Py_Finalize() calls are simply ignored. - Automatically import site.py on initialization, unless a flag is set not to do this by main().
* Removed obsolete exception PyExc_AccessError.Barry Warsaw1997-08-291-43/+171
| | | | | | | | | | | | | | | | | | | | | Added PyErr_MemoryErrorInst to hold the pre-instantiated instance when using class based exceptions. Simplified the creation of all built-in exceptions, both class based and string based. Actually, for class based exceptions, the string ones are still created just in case there's a problem creating the class based ones (so you still get *some* exception handling!). Now the init and fini functions run through a list of structure elements, creating the strings (and optionally classes) for every entry. initerrors(): the new base class exceptions StandardError, LookupError, and NumberError are initialized when using string exceptions, to tuples containing the list of derived string exceptions. This GvR trick enables forward compatibility! One bit of nastiness is that the C code has to know the inheritance tree embodied in exceptions.py. Added the two phase init and fini functions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the -X command line option. Py_Initialize(): Handle the two phase initialization of the built-in module. Py_Finalize(): Handle the two phase finalization of the built-in module. parse_syntax_error(): New function which parses syntax errors that PyErr_Print() will catch. This correctly parses such errors regardless of whether PyExc_SyntaxError is an old-style string exception or new-fangled class exception. PyErr_Print(): Many changes: 1. Normalize the exception. 2. Handle SystemExit exceptions which might be class based. Digs the exit code out of the "code" attribute. String based SystemExit is handled the same as before. 3. Handle SyntaxError exceptions which might be class based. Digs the various information bits out of the instance's attributes (see parse_syntax_error() for details). String based SyntaxError still works too. 4. Don't write the `:' after the exception if the exception is class based and has an empty string str() value.
