Guido van Rossum d085e88d3c Added Py_Malloc and friends as well as PyMem_Malloc and friends. 1997-08-05 01:59:22 +00:00
Guido van Rossum 29e46a9a12 Mass checkin (more to follow for other directories).
Introduce truly separate (sub)interpreter objects.  For now, these
must be used by separate threads, created from C.  See Demo/pysvr for
an example of how to use this.  This also rationalizes Python's
initialization and finalization behavior:

Py_Initialize() -- initialize the whole interpreter
Py_Finalize() -- finalize the whole interpreter

tstate = Py_NewInterpreter() -- create a new (sub)interpreter
Py_EndInterpreter(tstate) -- delete a new (sub)interpreter

There are also new interfaces relating to threads and the interpreter
lock, which can be used to create new threads, and sometimes have to
be used to manipulate the interpreter lock when creating or deleting
sub-interpreters.  These are only defined when WITH_THREAD is defined:

PyEval_AcquireLock() -- acquire the interpreter lock
PyEval_ReleaseLock() -- release the interpreter lock

PyEval_AcquireThread(tstate) -- acquire the lock and make the thread current
PyEval_ReleaseThread(tstate) -- release the lock and make NULL current

Other administrative changes:

- The header file bltinmodule.h is deleted.

- The init functions for Import, Sys and Builtin are now internal and
  declared in pythonrun.h.

- Py_Setup() and Py_Cleanup() are no longer declared.

- The interpreter state and thread state structures are now linked
  together in a chain (the chain of interpreters is a static variable
  in pythonrun.c).

- Some members of the interpreter and thread structures have new,
  shorter, more consistent, names.

- Added declarations for _PyImport_{Find,Fixup}Extension() to import.h.

Guido van Rossum 766118525a Changed the patch level to 1.5a3, to avoid confusion with a2 (I'm not
ready for a release yet).
1997-07-19 23:46:59 +00:00
Guido van Rossum 57d8e3f1c7 Added declarations for Py_{Set,Get}ProgramName() and a bunch of other
Py_Get*() functions.
1997-07-19 19:50:52 +00:00
Guido van Rossum 5617f32c5c Added decl for PyInt_GetMax(). 1997-07-19 19:49:11 +00:00
Guido van Rossum a847889607 Moved PyEval_InitThreads to inside WITH_THREAD, where it belongs. 1997-07-19 19:27:30 +00:00
Guido van Rossum e6fb2043ce Got rid of "suppres printing" flag. 1997-07-19 19:26:38 +00:00
Guido van Rossum 618af4b3ef Include pystate.h earlier so it can be referenced by ceval.h. 1997-07-18 23:59:26 +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.

Guido van Rossum 4b11c74f7c Only add 1 byte to all malloc calls when it is known that malloc(0) or
realloc(p, 0) returns NULL.  See changes to configure script to be
checked in later.

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 fdf95dd525 Checkin of Jack's buffer mods.
Not really checked, but didn't fail any tests either...
1997-05-05 22:15:02 +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 d27b4f2a3f Several oopsies -- Py_ALLOBJECTS_H -> Py_PYTHON_H, temporarily removed
pystate.h (to be restored later when that code is debugged), removed
accessobject.h.
1997-05-02 04:00:11 +00:00
Guido van Rossum 174f95adf7 Moved allobjects.h to Python.h (without rename2.h).
allobjects.h disappears -- old-style extensions must include Python.h
and rename2.h.
1997-05-02 03:55:52 +00:00

Guido van Rossum 63c35e5407 Remove macros that are only used for cgensupport.[ch].
Fixed typo in PyArg_VaParse (not PyArgs_*).
1997-04-29 16:21:39 +00:00
Guido van Rossum 92e8782217 Moved cgensupport.h to Modules (awaiting oblivion). 1997-04-29 16:08:53 +00:00
Guido van Rossum 1818b7702b Moved rename2's macros relevant to this module here and added comment
about the file's obsolescence.
1997-04-29 15:35:28 +00:00
Guido van Rossum 45c3aaba56 Got rid of the static decl of PyCObject_Import, which was a 1.4
compatibility hack.
1997-04-09 18:04:08 +00:00
Guido van Rossum 0a73dd5f35 Changed the way the C API was exported. Jim Fulton. 1997-04-09 17:34:28 +00:00

Guido van Rossum 94dbd99483 Remove ConflictError (which was also removed from bltinmodule.c, even
though the checkin message failed to note that).
1997-03-31 17:19:40 +00:00
Guido van Rossum e053c67780 Remove err_input -- there is no such global! 1997-03-14 05:09:30 +00:00
Guido van Rossum f0958064f9 Remove redundant references to thread stuff -- long, long ago, there
was some locking code in this file that needed it...
1997-03-14 04:25:22 +00:00
Guido van Rossum 74277916a9 Add Macros defining new names for all external symbols. 1997-03-14 04:24:08 +00:00
Guido van Rossum 1f06beeedd Change PyFPE_END_PROTECT to PyFPE_END_PROTECT(v). v should be the
last variable to which a floating point expression is assigned.  The
macro passes its address to a dummy function so that the optimizer
can't delay calculating its value until after the macro.
1997-03-14 04:23:42 +00:00
Guido van Rossum f39fc43f31 A few comment alignment and clarifications. 1997-03-04 18:31:47 +00:00

See frameobject.c checkin message.
1997-01-20 04:16:40 +00:00
Guido van Rossum ee5cf9b672 Bump API version due to the various speedup hacks. 1997-01-18 07:54:03 +00:00
Guido van Rossum 1e6e9a2368 Two speedup hacks. Caching the hash saves recalculation of a string's
hash value.  Interning strings (which requires hash caching) tries to
ensure that only one string object with a given value exists, so
equality tests are one pointer comparison.  Together, these can speed
the interpreter up by as much as 20%.  Each costs the size of a long
or pointer per string object.  In addition, interned strings live
until the end of times.  If you are concerned about memory footprint,
simply comment the #define out here (and rebuild everything!).
1997-01-18 07:53:23 +00:00
Guido van Rossum 3f6e408a31 Add co_stacksize field to codeobject structure, and stacksize argument
to PyCode_New() argument list.  Also add CO_MAXBLOCKS constant
indicating the maximum static nesting supported by the compiler.

Barry Warsaw 1f2bd07aed added PyList_GET_SIZE macro
for both PyList_GET_SIZE and PyList_GET_ITEM, cast first argument to a
PyListObject*
1997-01-06 22:42:00 +00:00
Guido van Rossum 53756b1097 Added PyLong_FromUnsignedLong() and PyLong_AsUnsignedLong(). 1997-01-03 17:14:46 +00:00

Guido van Rossum 58055847f4 Changed version to plain "1.4". 1996-10-22 03:09:46 +00:00
Guido van Rossum b75fba04c7 Forget about Ellipses b/w compatibility. 1996-10-16 04:18:36 +00:00
Guido van Rossum e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
1996-10-11 16:25:41 +00:00
Guido van Rossum a63518436a Add waitflag to down_sema(). 1996-10-08 14:21:49 +00:00
Guido van Rossum c8ce571c16 Rationalized PC compiler defines: require MS_WINDOWS or __BORLANDC__
or __WATCOMC__.  Add ALTSEP for PC filesystems.
1996-09-11 20:20:58 +00:00

Guido van Rossum 2a516c8f2c Bump patchlevel (a bit early, but what the heck...) 1996-08-22 23:15:05 +00:00
Guido van Rossum 2ea0b06498 Add PYTHON_API_STRING, which is PYTHON_API_VERSION as a string literal.
Under Windows, add MS_DLL_ID and MS_DLL_VERSION_ID for Mark H.

Independent change: if Py_TRACE_REFS is defined, rename Py_InitModule4
so so linking with incompatible modules will create a link time error.

[Backing out of previous changes (also for modsupport.c) to test
the latter at runtime.]
