Raymond Hettinger cb87bc8e7e Add weakref support to array.array and file objects. 2004-05-31 00:35:52 +00:00
Raymond Hettinger 691d80532b Make sets and deques weak referencable. 2004-05-30 07:26:47 +00:00
Raymond Hettinger 354433a59d SF patch #872326: Generator expression implementation
(Code contributed by Jiwon Seo.)

The documentation portion of the patch is being re-worked and will be
checked-in soon.  Likewise, PEP 289 will be updated to reflect Guido's
rationale for the design decisions on binding behavior (as described in
in his patch comments and in discussions on python-dev).

The test file, test_genexps.py, is written in doctest format and is
meant to exercise all aspects of the the patch.  Further additions are
welcome from everyone.  Please stress test this new feature as much as
possible before the alpha release.

Nicholas Bastin a7604bf1b4 Moved tracebackobject to traceback.h, Closes SF Bug #497067 2004-03-21 18:37:23 +00:00
Skip Montanaro 6e098a15a3 compile.h and eval.h weren't being included which kept a fair bit of the
public API from being exposed by simply including Python.h (as recommended).

Raymond Hettinger 42bec93e5c Make PySequence_Fast_ITEMS public. (Thanks Skip.) 2004-03-12 16:38:17 +00:00
Raymond Hettinger c1e4f9dd92 Use a new macro, PySequence_Fast_ITEMS to factor out code common to
three recent optimizations.  Aside from reducing code volume, it
increases readability.
2004-03-12 08:04:00 +00:00
Raymond Hettinger 8ca92ae54c Eliminate a big block of duplicate code in PySequence_List() by
exposing _PyList_Extend().

Raymond Hettinger dd80f76265 SF patch #910929: Optimize list comprehensions
Add a new opcode, LIST_APPEND, and apply it to the code generation for
list comprehensions.  Reduces the per-loop overhead by about a third.
2004-03-07 07:31:06 +00:00
Raymond Hettinger 4bb9540dd6 * Optimized list appends and pops by making fewer calls the underlying system
realloc().  This is achieved by tracking the overallocation size in a new
  field and using that information to skip calls to realloc() whenever
  possible.

* Simplified and tightened the amount of overallocation.  For larger lists,
  this overallocates by 1/8th (compared to the previous scheme which ranged
  between 1/4th to 1/32nd over-allocation).  For smaller lists (n<6), the
  maximum overallocation is one byte (formerly it could be upto eight bytes).
  This saves memory in applications with large numbers of small lists.

* Eliminated the NRESIZE macro in favor of a new, static list_resize function
  that encapsulates the resizing logic.  Coverting this back to macro would
  give a small (under 1%) speed-up.  This was too small to warrant the loss
  of readability, maintainability, and de-coupling.

* Some functions using NRESIZE had grown unnecessarily complex in their
  efforts to bend to the macro's calling pattern.  With the new list_resize
  function in place, those other functions could be simplified.  That is
  being saved for a separate patch.

* The ob_item==NULL check could be eliminated from the new list_resize
  function.  This would entail finding each piece of code that sets ob_item
  to NULL and adding a new line to invalidate the overallocation tracking
  field.  Rather than impose a new requirement on other pieces of list code,
  it was preferred to leave the NULL check in place and retain the benefits
  of decoupling, maintainability and information hiding (only PyList_New()
  and list_sort() need to know about the new field).  This approach also
  reduces the odds of breaking an extension module.

(Collaborative effort by Raymond Hettinger, Hye-Shik Chang, Tim Peters,
 and Armin Rigo.)

Jeremy Hylton 87c1afa057 Fix name problem in previous checkin: Dict not List 2003-12-26 17:17:49 +00:00
Andrew MacIntyre e99990f9e1 At 2.2, the Py<type>_Check() family of API functions (macros) changed
semantics to include subtypes.  Most concrete object APIs then had
a Py<type>_CheckExact() macro added to test for an object's type
not including subtypes.

The PyDict_CheckExact() macro wasn't created at that time, so I've added
it for API completeness/symmetry - even though nobody has complained
about its absence in the time since 2.2 was released.

Not a backport candidate.

Andrew MacIntyre 43e5711309 The semantics of PyList_Check() and PyDict_Check() changed at 2.2, along

Tim Peters 0490fe96d8 Changed the UCHAR_MAX error msg a bit: we don't really assume anything
about "characters", we assume something about C's char type (which is
an integral type).
2003-12-22 18:10:51 +00:00
Skip Montanaro ac4ea13a3a There are places in Python which assume bytes have 8-bits. Formalize that a
bit by checking the value of UCHAR_MAX in Include/Python.h.  There was a
check in Objects/stringobject.c.  Remove that.  (Note that we don't define
UCHAR_MAX if it's not defined as the old test did.)

Jason Tishler 6bc06eca70 Bug #794140: cygwin builds do not embed
The embed2.diff patch solves the user's problem by exporting the missing
symbols from the Python core so Python can be embedded in another Cygwin
application (well, at lest vim).
2003-09-04 11:59:50 +00:00
Jason Tishler 3076559ea5 This patch enables the building of Cygwin Python with a static core
which still supports shared extensions. It takes advantage the latest
Cygwin binutils (i.e., 20030901-1) which can export symbols from
executables:

Guido van Rossum b8b6d0c2c6 Add PyThreadState_SetAsyncExc(long, PyObject *).
A new API (only accessible from C) to interrupt a thread by sending it

Requested by Just van Rossum and Alex Martelli.  It is intentional
that you have to write your own C extension to call it from Python.

Docs will have to wait.

Raymond Hettinger f4cf76dd5e Revert the previous enhancement to the bytecode optimizer.
The additional code complexity and new NOP opcode were not worth it.
2003-04-24 05:45:23 +00:00
Raymond Hettinger 060641d511 Improved the bytecode optimizer.
* Can now test for basic blocks.
* Optimize inverted comparisions.
* Optimize unary_not followed by a conditional jump.
* Added a new opcode, NOP, to keep code size constant.
* Applied NOP to previous transformations where appropriate.

Note, the NOP would not be necessary if other functions were
added to re-target jump addresses and update the co_lnotab mapping.
That would yield slightly faster and cleaner bytecode at the
expense of optimizer simplicity and of keeping it decoupled
from the line-numbering structure.

Mark Hammond 8d98d2cb95 New PyGILState_ API - implements pep 311, from patch 684256. 2003-04-19 15:41:53 +00:00
Tim Peters 269b2a6797 _Py_PrintReferences(): Changed to print object address at start of each
new line.

New pvt API function _Py_PrintReferenceAddresses():  Prints only the
addresses and refcnts of the live objects.  This is always safe to call,
because it has no dependence on Python's C API.

Py_Finalize():  If envar PYTHONDUMPREFS is set, call (the new)
_Py_PrintReferenceAddresses() right before dumping final pymalloc stats.
We can't print the reprs of the objects here because too much of the
interpreter has been shut down.  You need to correlate the addresses
displayed here with the object reprs printed by the earlier
PYTHONDUMPREFS call to _Py_PrintReferences().
2003-04-17 19:52:29 +00:00
Thomas Heller a4ea603b05 SF # 595026: support for masks in getargs.c.
New functions:
  unsigned long PyInt_AsUnsignedLongMask(PyObject *);
  unsigned PY_LONG_LONG) PyInt_AsUnsignedLongLongMask(PyObject *);
  unsigned long PyLong_AsUnsignedLongMask(PyObject *);
  unsigned PY_LONG_LONG) PyLong_AsUnsignedLongLongMask(PyObject *);

New and changed format codes:

b unsigned char 0..UCHAR_MAX
B unsigned char none **
h unsigned short 0..USHRT_MAX
H unsigned short none **
i int INT_MIN..INT_MAX
I * unsigned int 0..UINT_MAX
l long LONG_MIN..LONG_MAX
k * unsigned long none
L long long LLONG_MIN..LLONG_MAX
K * unsigned long long none

Notes:

* New format codes.

** Changed from previous "range-and-a-half" to "none"; the
range-and-a-half checking wasn't particularly useful.

New test test_getargs2.py, to verify all this.

Martin v. Löwis b9a0f91218 Rename LONG_LONG to PY_LONG_LONG. Fixes #710285. 2003-03-29 10:06:18 +00:00
Tim Peters 7571a0fbcf Improved new Py_TRACE_REFS gimmicks.
Arranged that all the objects exposed by __builtin__ appear in the list
of all objects.  I basically peed away two days tracking down a mystery
leak in sys.gettotalrefcount() in a ZODB app (== tons of code), because
the object leaking the references didn't appear in the sys.getobjects(0)
list.  The object happened to be False.  Now False is in the list, along
with other popular & previously missing leak candidates (like None).
Alas, we still don't have a choke point covering *all* Python objects,
so the list of all objects may still be incomplete.
2003-03-23 17:52:28 +00:00
Tim Peters 36eb4dfb81 Refactored some of the Py_TRACE_REFS code. New private API function
_Py_AddToAllObjects() that simply inserts an object at the front of
the doubly-linked list of all objects.  Changed PyType_Ready() (the
 closest thing we've got to a choke point for type objects) to call
that.
2003-03-23 03:33:13 +00:00
Tim Peters 9905b943f7 New private API functions _PyFloat_{Pack,Unpack}(4,8}. This is a
refactoring to get all the duplicates of this delicate code out of the
cPickle and struct modules.
2003-03-20 20:53:32 +00:00
Gustavo Niemeyer 5ddd4c3f77 Fixed SF bug #663074. The codec system was using global static
variables to store internal data. As a result, any atempts to use the
unicode system with multiple active interpreters, or successive
interpreter executions, would fail.

Now that information is stored into members of the PyInterpreterState
structure.

Remove prototype and doc.  Backport candidate.

Jack Jansen d00c13a9be Moved the Apple workaround for the guard define for wchar_t out of
the #ifdef HAVE_NCURSES_H: the same problem exists on OSX 10.1 with
a fink-installed curses (which uses curses.h as the include file name).

Guido van Rossum 81e26590e4 Update PY_VERSION to indicate that we're beyond 2.3a2 now. 2003-02-20 18:46:54 +00:00
Michael W. Hudson 2aec8b744e As far as I can tell PyEval_GetOwner was removed in 1997 (when it was
called something else!).  I can't imagine removing the prototype is
going to hurt, but put it back if *you* can.
2003-02-20 17:59:17 +00:00
Guido van Rossum 6297a7a9fb - PyEval_GetFrame() is now declared to return a PyFrameObject *

Tim Peters 1441cf9dfc Bump version # to 2.3a2. 2003-02-18 21:58:53 +00:00
Guido van Rossum 4b499dd3fb - Finally fixed the bug in compile() and exec where a string ending
with an indented code block but no newline would raise SyntaxError.
  This would have been a four-line change in parsetok.c...  Except
  codeop.py depends on this behavior, so a compilation flag had to be
  invented that causes the tokenizer to revert to the old behavior;
  this required extra changes to 2 .h files, 2 .c files, and 2 .py
  files.  (Fixes SF bug #501622.)

Jeremy Hylton 985eba53f5 Small function call optimization and special build option for call stats.
-DCALL_PROFILE: Count the number of function calls executed.

When this symbol is defined, the ceval mainloop and helper functions
count the number of function calls made.  It keeps detailed statistics
about what kind of object was called and whether the call hit any of
the special fast paths in the code.

Optimization:

When we take the fast_function() path, which seems to be taken for
most function calls, and there is minimal frame setup to do, avoid
call PyEval_EvalCodeEx().  The eval code ex function does a lot of
work to handle keywords args and star args, free variables,
generators, etc.  The inlined version simply allocates the frame and
copies the arguments values into the frame.

The optimization gets a little help from compile.c which adds a
CO_NOFREE flag to code objects that don't have free variables or cell
variables.  This change allows fast_function() to get into the fast
path with fewer tests.

I measure a couple of percent speedup in pystone with this change, but
there's surely more that can be done.
2003-02-05 23:13:00 +00:00
Jeremy Hylton 4f0dcc9a9a Provide __module__ attributes for functions defined in C and Python.
__module__ is the string name of the module the function was defined
in, just like __module__ of classes.  In some cases, particularly for
C functions, the __module__ may be None.

Change PyCFunction_New() from a function to a macro, but keep an
unused copy of the function around so that we don't change the binary
API.

Change pickle's save_global() to use whichmodule() if __module__ is
None, but add the __module__ logic to whichmodule() since it might be
used outside of pickle.
2003-01-31 18:33:18 +00:00
Tim Peters 5b8132ffa3 _PyLong_NumBits(): The definition of this was too specific to the quirky
needs of pickling longs.  Backed off to a definition that's much easier
to understand.  The pickler will have to work a little harder, but other
uses are more likely to be correct <0.5 wink>.

_PyLong_Sign():  New teensy function to characterize a long, as to <0, ==0,
or >0.
2003-01-31 15:52:05 +00:00
Tim Peters baefd9e552 Added new private API function _PyLong_NumBits. This will be used at the
start for the C implemention of new pickle LONG1 and LONG4 opcodes (the
linear-time way to pickle a long is to call _PyLong_AsByteArray, but
the caller has no idea how big an array to allocate, and correct
calculation is a bit subtle).

Jack Jansen b2a57722a8 It turns out that some calls return AEDesc records that are "borrowed",
the AEDesc data shouldn't be disposed when the Python object is.

Added a C call AEDesc_NewBorrowed() to create these objects and a Python
method old=AEDesc.AutoDispose(onoff) to change auto-dispose state.

Tim Peters a032d2eb7f Minor fiddling to make the next part easier. Introduced an internal
HASTZINFO() macro.
2003-01-11 00:15:54 +00:00
Tim Peters 37f398282b Got rid of the timetz type entirely. This was a bit trickier than I
hoped it would be, but not too bad.  A test had to change:
time.__setstate__() can no longer add a non-None tzinfo member to a time
object that didn't already have one, since storage for a tzinfo member
doesn't exist in that case.

Jason Tishler fb8595df4f Patch #661760: Cygwin auto-import module patch
The attached patch enables shared extension
modules to build cleanly under Cygwin without
moving the static initialization of certain function
pointers (i.e., ones exported from the Python
DLL core) to a module initialization function.

Additionally, this patch fixes the modules that
have been changed in the past to accommodate
Cygwin.

Just van Rossum 52e14d640b PEP 302 + zipimport:
- new import hooks in import.c, exposed in the sys module
- new module called 'zipimport'
- various changes to allow bootstrapping from zip files

I hope I didn't break the Windows build (or anything else for that
matter), but then again, it's been sitting on sf long enough...

Regarding the latest discussions on python-dev: zipimport sets
pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as
/path/to/Archive.zip/subdir/ are supported again.
2002-12-30 22:08:05 +00:00
Tim Peters 4643bd9a9c Apparently FreeBSD enables some HW floating-point exceptions by default.
This can cause core dumps when Python runs.  Python relies on the 754-
(and C99-) mandated default "non-stop" mode for FP exceptions.  This
patch from Ben Laurie disables at least one FP exception on FreeBSD at
Python startup time.

Guido van Rossum 73d66925d9 Rearrange the members of struct _node to put shorter fields towards
the end, in the hope of saving some bytes on 64-bit machines.  (Too
bad n_nchildren can't be made an unsigned short, but
test/test_longexp.py specifically tests for more than 2**16 subtrees
at one level.)

I don't expect any binary compatibility issues here, unless someone
has an old binary of parsermodule.so saved away.

Skip Montanaro d581d7792b replace thread state objects' ticker and checkinterval fields with two

test in the main loop to only test a single value.

Michael W. Hudson 53d58bb369 Further SET_LINENO reomval fixes. See comments in patch #587933.
Use a slightly different strategy to determine when not to call the line

that's gone again.  Update docs and comments to match.

Thanks to Neal and Armin!

Also add a test suite.  This should have come with the original patch...

Guido van Rossum 45ec02aed1 SF patch 576101, by Oren Tirosh: alternative implementation of
interning.  I modified Oren's patch significantly, but the basic idea
and most of the implementation is unchanged.  Interned strings created
with PyString_InternInPlace() are now mortal, and you must keep a
reference to the resulting string around; use the new function
PyString_InternImmortal() to create immortal interned strings.
