Guido van Rossum 2571cc8bf5 Changes by Mark Hammond for Windows CE. Mostly of the form
#ifdef DONT_HAVE_header_H ... #endif around #include <header.h>.
1999-04-07 16:07:23 +00:00
Guido van Rossum eb894ebd0a Always test for an error return (usually NULL or -1) without setting
an exception.
1999-03-09 16:16:45 +00:00
Guido van Rossum 65d5b5763c Thanks to Chris Herborth, the thread primitives now have proper Py*
names in the source code (they already had those for the linker,
through some smart macros; but the source still had the old, un-Py names).
1998-12-21 19:32:43 +00:00
Guido van Rossum 885553e8d3 Use PyThreadState_GET() macro. 1998-12-21 18:33:30 +00:00
Guido van Rossum cf183acf15 Use PyInt_AS_LONG macro instead of explicit inlining. 1998-12-04 18:51:36 +00:00
Guido van Rossum 014518f66c Whoops! One the "redundant" initializations removed by Vladimir in
the previous patch wasn't -- there was a path through the code that
bypassed all initializations.  Thanks to Just for reporting the bug!
1998-11-23 21:09:51 +00:00
Guido van Rossum 50cd34888b Remove some redundant initializations -- patch by Vladimir Marangozov. 1998-11-17 17:02:51 +00:00
Guido van Rossum d076c73cc8 Changes to support other object types besides strings
as the code string of code objects, as long as they support
the (readonly) buffer interface.  By Greg Stein.
1998-10-07 19:42:25 +00:00
Guido van Rossum 49b560698b Renamed thread.h to pythread.h. 1998-10-01 20:42:43 +00:00
Guido van Rossum 2d1ad39b81 Add the type of the object to the error message about calling a non-function. 1998-08-25 18:16:54 +00:00
Guido van Rossum 5053efc2c4 In BUILD_LIST, use PyList_SET_ITEM() instead of PyList_SetItem(); and
get rid of redundant error check.
1998-08-04 15:27:50 +00:00
Guido van Rossum fa00e958fd # In case BINARY_SUBSCR, use proper PyList_GET* macros instead of inlining. 1998-07-08 15:02:37 +00:00
Guido van Rossum 7859f87fdb Marc-Andre Lemburg's patch to support instance methods with other
callable objects than regular Pythonm functions as their im_func.
1998-07-08 14:58:16 +00:00
Guido van Rossum 7e33c6e896 Moved cmp_member() to abstract.c, as PySequence_Contains() [with
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.
1998-05-22 00:52:29 +00:00
Guido van Rossum 234e260d5e Since PyDict_GetItem() can't raise an exception any more, there's no
need to call PyErr_Clear() when it returns NULL.
1998-05-14 02:16:20 +00:00
Guido van Rossum 2e4c899e2d DELETE_FAST should issue an exception when the local variable is undefined. 1998-05-12 20:27:36 +00:00
Guido van Rossum 730806d3d9 Make new gcc -Wall happy 1998-04-10 22:27:42 +00:00
Guido van Rossum d295f120ae Make first raise argument optional 1998-04-09 21:39:57 +00:00
Guido van Rossum 8f18320270 Last-minute fix for Jim H: don't die after del sys.stdout 1997-12-31 05:53:15 +00:00
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).
1997-12-26 22:15:57 +00:00
Guido van Rossum df9db1ea18 Give more detailed error message when the argument count isn't right. 1997-11-19 16:05:40 +00:00
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.
1997-11-11 16:29:38 +00:00
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)'').
1997-09-30 22:03:16 +00:00
Guido van Rossum aee0bad0a5 First part of package support.
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!

Guido van Rossum d7ed683a7e Inline PyObject_CallObject (Marc-Andre Lemburg). 1997-08-30 15:02:50 +00:00
Barry Warsaw eaedc7ce32 eval_code2(), set_exc_info(): Call PyErr_NormalizeException() the
former rather than the latter, since PyErr_NormalizeException takes
PyObject** and I didn't want to change the interface for set_exc_info
(but I did want the changes propagated to eval_code2!).
1997-08-28 22:36:40 +00:00
Barry Warsaw 910105515e unpack_sequence(): In finally clause, watch out for Py_DECREF
evaluating its arguments twice.
1997-08-25 22:30:51 +00:00
Barry Warsaw e42b18f9d1 eval_code2(): collapsed the implementations of UNPACK_TUPLE and
UNPACK_LIST byte codes and added a third code path that allows
generalized sequence unpacking.  Now both syntaxes:

    a, b, c = seq
    [a, b, c] = seq

can be used to unpack any sequence with the exact right number of
items.

unpack_sequence(): out-lined implementation of generalized sequence
unpacking.  tuple and list unpacking are still inlined.
1997-08-25 22:13:04 +00:00
Barry Warsaw 4249f54b28 cmp_exception gets promoted (essentially) to the C API function
PyErr_GivenExceptionMatches().

set_exc_info(): make sure to normalize exceptions.

do_raise(): Use PyErr_NormalizeException() if type is a class.

loop_subscript(): Use PyErr_ExceptionMatches() instead of raw pointer
compare for PyExc_IndexError.
1997-08-22 21:26:19 +00:00
Guido van Rossum cd649654d7 Reverse the search order for the Don Beaudry hook so that the first
class wins.  Makes more sense.
1997-08-22 16:56:16 +00:00
Guido van Rossum f9c90c533e Renamed a local label that was accidentally grandly renamed to
'Py_Cleanup' back to 'cleanup'.
1997-08-05 02:18:01 +00:00
Guido van Rossum 25ce566661 The last of the mass checkins for separate (sub)interpreters.
Everything should now work again.

See the comments for the .h files mass checkin (e.g. pystate.h) for
more detail.
1997-08-02 03:10:38 +00:00
Guido van Rossum 55b9ab5bdb Extend the "Don Beaudry hack" with "Guido's corollary" -- if the base
class has a __class__ attribute, call that to create the new class.
This allows us to write metaclasses purely in C!
1997-07-31 03:54:02 +00:00
Guido van Rossum 9cc8a20cd2 Moved PyEval_{Acquire,Release}Thread() to within the same #ifdef
WITH_THREAD as PyEval_InitThreads().

Removed use of Py_SuppressPrintingFlag.
1997-07-19 19:55:50 +00:00
Guido van Rossum 2fca21f762 PyEval_SaveThread() and PyEval_RestoreThread() now return/take a
PyThreadState pointer instead of a (frame) PyObject pointer.  This
makes much more sense.  It is backward incompatible, but that's no
problem, because (a) the heaviest users are the Py_{BEGIN,END}_
ALLOW_THREADS macros here, which have been fixed too; (b) there are
very few direct users; (c) those who use it are there will probably
appreciate the change.

Also, added new functions PyEval_AcquireThread() and
PyEval_ReleaseThread() which allows the threads created by the thread
module as well threads created by others (!) to set/reset the current
thread, and at the same time acquire/release the interpreter lock.

Much saner.
1997-07-18 23:56:58 +00:00
Guido van Rossum c12da6980f Huge speedup by inlining some common integer operations:
int+int, int-int, int <compareop> int, and list[int].
(Unfortunately, int*int is way too much code to inline.)

Also corrected a NULL that should have been a zero.
1997-07-17 23:12:42 +00:00
Guido van Rossum c8b6df9004 PyObject_Compare can raise an exception now. 1997-05-23 00:06:51 +00:00
Guido van Rossum be27026c09 Py_FlushLine and PyFile_WriteString now return error indicators
instead of calling PyErr_Clear().  Add checking of those errors.
1997-05-22 22:26:18 +00:00
Guido van Rossum df4c308f5a Plug leak of stack frame object in exception handling code.
Also delay DECREF calls until after the structures have been updated
(for reentrancy awareness).
1997-05-20 17:06:11 +00:00
Guido van Rossum df0d00e29b Logic for enabling mac-specific signal handling fixed (Jack) 1997-05-20 15:57:49 +00:00
Guido van Rossum 5f15b96c36 (int) cast for strlen() to keep picky compilers happy. 1997-05-13 17:50:01 +00:00
Guido van Rossum b05a5c7698 Instead of importing graminit.h whenever one of the three grammar 'root'
symbols is needed, define these in Python.h with a Py_ prefix.
1997-05-07 17:46:13 +00:00
Guido van Rossum fc49073cd0 Used operators from abstract.h where possible (arithmetic operators,
get/set/del item).  This removes a pile of duplication.  There's no
abstract operator for 'not' but I removed the function call for it
anyway -- it's a little faster in-line.
1997-05-06 15:06:49 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management.
All per-thread globals are moved into a struct which is manipulated
separately.
1997-05-05 20:56:21 +00:00
Guido van Rossum b209a116cf Quickly renamed. 1997-04-29 18:18:01 +00:00
Guido van Rossum c43b685054 Clarify error message for unexpected keyword parameter. 1997-03-10 22:58:23 +00:00
Guido van Rossum 0d85be19e2 *Don't* kill all local variables on function exit. This will be done
by the frameobject dealloc when it is time for the locals to go.  When
there's still a traceback object referencing this stack frame, we
don't want the local variables to disappear yet.

(Hmm...  Shouldn't they be copied to the f_locals dictionary?)
1997-02-14 16:32:14 +00:00
Guido van Rossum deb0c5e66c Two small changes:
- Use co->... instead of f->f_code->...; save an extra lookup of what
we already have in a local variable).

- Remove test for nlocals > 0 before setting fastlocals to
f->f_localsplus; 0 is a rare case and the assignment is safe even
then.
1997-01-27 23:42:36 +00:00
Guido van Rossum d0eb429b88 Plug a leak with calling something other than a function or method is
called with keyword arguments -- the keyword and value were leaked.
This affected for instance with a __call__() method.

Bug reported and fix supplied by Jim Fulton.
1997-01-27 21:30:09 +00:00
Guido van Rossum 950361c6ca Patches for (two forms of) optional dynamic execution profiling --
i.e., counting opcode frequencies, or (with DXPAIRS defined) opcode
pair frequencies.  Define DYNAMIC_EXECUTION_PROFILE on the command
line (for this file and for sysmodule.c) to enable.
