Barry Warsaw 2a38a86c1c Expose Subversion revision number (calculated via "svnversion .") to Python.
Add C API function Py_GetBuildNumber(), add it to the interactive prompt
banner (i.e. Py_GetBuildInfo()), and add it as the sys.build_number
attribute.  The build number is a string instead of an int because it may
contain a trailing 'M' if there are local modifications.

Neal Norwitz 897ff817d5 SF #1373150, diffs in working copy after a build
Strip off leading dots and slash so the generated files are the same regardless
of whether you configure in the checkout directory or build.

If anyone configures in a different directory, we might want a cleaner
approach using os.path.*().  Hopefully this is good enough.

Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Michael W. Hudson ba283e2b7f This is my patch:
[ 1181301 ] make float packing copy bytes when they can

which hasn't been reviewed, despite numerous threats to check it in
anyway if noone reviews it.  Please read the diff on the checkin list,
at least!

The basic idea is to examine the bytes of some 'probe values' to see if
the current platform is a IEEE 754-ish platform, and if so
_PyFloat_{Pack,Unpack}{4,8} just copy bytes around.

The rest is hair for testing, and tests.

Raymond Hettinger ec6eb369d5 SF patch #1035255: Remove CoreServices / CoreFoundation dependencies in core
(Contributed by Bob Ippolito.)

This patch trims down the Python core on Darwin by making it
independent of CoreFoundation and CoreServices. It does this by:

Changed linker flags in configure/configure.in
Removed the unused PyMac_GetAppletScriptFile
Moved the implementation of PyMac_StrError to the MacOS module
Moved the implementation of PyMac_GetFullPathname to the
Carbon.File module

Armin Rigo 89a39461bf Wrote down the invariants of some common objects whose structure is
exposed in header files.  Fixed a few comments in these headers.

As we might have expected, writing down invariants systematically exposed a
(minor) bug.  In this case, function objects have a writeable func_code
attribute, which could be set to code objects with the wrong number of
free variables.  Calling the resulting function segfaulted the interpreter.
Added a corresponding test.

Tim Peters 47e52ee0c5 SF patch 936813: fast modular exponentiation
This checkin is adapted from part 2 (of 3) of Trevor Perrin's patch set.

BACKWARD INCOMPATIBILITY:  SHIFT must now be divisible by 5.  AFAIK,
nobody will care.  long_pow() could be complicated to worm around that,
if necessary.

long_pow():
  - BUGFIX:  This leaked the base and power when the power was negative
    (and so the computation delegated to float pow).
  - Instead of doing right-to-left exponentiation, do left-to-right.  This
    is more efficient for small bases, which is the common case.
  - In addition, if the exponent is large (more than FIVEARY_CUTOFF
    digits), precompute [a**i % c for i in range(32)], and go left to
    right 5 bits at a time.
l_divmod():
  - The signature changed so that callers who don't want the quotient,
    or don't want the remainder, can pass NULL in the slot they don't
    want.  This saves them from having to declare a vrbl for unwanted
    stuff, and remembering to decref it.
long_mod(), long_div(), long_classic_div():
  - Adjust to new l_divmod() signature, and simplified as a result.

Tim Peters 0973b99e1c SF patch 936813: fast modular exponentiation
This checkin is adapted from part 1 (of 3) of Trevor Perrin's patch set.

x_mul()
  - sped a little by optimizing the C
  - sped a lot (~2X) if it's doing a square; note that long_pow() squares
    often
k_mul()
  - more cache-friendly now if it's doing a square
KARATSUBA_CUTOFF
  - boosted; gradeschool mult is quicker now, and it may have been too low
    for many platforms anyway
KARATSUBA_SQUARE_CUTOFF
  - new
  - since x_mul is a lot faster at squaring now, the point at which
    Karatsuba pays for squaring is much higher than for general mult

Neal Norwitz 4ecd8cd046 Fix typo in comment 2004-08-01 22:45:27 +00:00
Armin Rigo 93677f075d * drop the unreasonable list invariant that ob_item should never come back
to NULL during the lifetime of the object.

* listobject.c nevertheless did not conform to the other invariants,
  either; fixed.

* listobject.c now uses list_clear() as the obvious internal way to clear
  a list, instead of abusing list_ass_slice() for that.  It makes it easier
  to enforce the invariant about ob_item == NULL.

* listsort() sets allocated to -1 during sort; any mutation will set it
  to a value >= 0, so it is a safe way to detect mutation.  A negative
  value for allocated does not cause a problem elsewhere currently.
  test_sort.py has a new test for this fix.

* listsort() leak: if items were added to the list during the sort, AND if
  these items had a __del__ that puts still more stuff into the list,
  then this more stuff (and the PyObject** array to hold them) were
  overridden at the end of listsort() and never released.
2004-07-29 12:40:23 +00:00
Tim Peters 51b4ade306 Fix obscure breakage (relative to 2.3) in listsort: the test for list
mutation during list.sort() used to rely on that listobject.c always
NULL'ed ob_item when ob_size fell to 0.  That's no longer true, so the
test for list mutation during a sort is no longer reliable.  Changed the
test to rely instead on that listobject.c now never NULLs-out ob_item
after (if ever) ob_item gets a non-NULL value.  This new assumption is
also documented now, as a required invariant in listobject.h.

The new assumption allowed some real simplification to some of the
hairier code in listsort(), so is a Good Thing on that count.

Rewrote Py_RETURN_{NONE, TRUE, FALSE} to expand to comma expressions
rather than "do {} while(0)" thingies.  The OP complained because he
likes using MS /W4 sometimes, and then all his uses of these things
generate nuisance warnings about testing a constant expression (in
the "while(0)" part).  Comma expressions don't have this problem
(although it's a lucky accident that comma expressions suffice for these
macros!).

Fred Drake 0a4dd390bf Make weak references subclassable:
- weakref.ref and weakref.ReferenceType will become aliases for each
  other

- weakref.ref will be a modern, new-style class with proper __new__
  and __init__ methods

- weakref.WeakValueDictionary will have a lighter memory footprint,
  using a new weakref.ref subclass to associate the key with the
  value, allowing us to have only a single object of overhead for each
  dictionary entry (currently, there are 3 objects of overhead per
  entry: a weakref to the value, a weakref to the dictionary, and a
  function object used as a weakref callback; the weakref to the
  dictionary could be avoided without this change)

- a new macro, PyWeakref_CheckRefExact(), will be added

- PyWeakref_CheckRef() will check for subclasses of weakref.ref

This closes SF patch #983019.

New include file timefuncs.h exports private API function
_PyTime_DoubleToTimet() from timemodule.c.  timemodule should export
some other functions too (look for painful bits in datetimemodule.c).

Added insane-argument checking to datetime's assorted fromtimestamp()
and utcfromtimestamp() methods.  Added insane-argument tests of these
to test_datetime, and insane-argument tests for ctime(), localtime()
and gmtime() to test_time.

(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.

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.)

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.

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.

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().

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.

Guido van Rossum e13ddc9ec8 - New C API PyGC_Collect(), same as calling gc.collect().
- Call this in Py_Finalize().
- Expand the Misc/NEWS text on PY_LONG_LONG.

Guido van Rossum d3ab37f1df Changes from Jonathan Riehl to allow his pgen extension (PEP 269) to
work.  This includes some more code that used to be part of pgen in
the main parser; I'm okay with that.  I'll see if the Windows build
needs work next.

Guido van Rossum a12fe4e81f - New function sys.call_tracing() allows pdb to debug code
recursively.
- pdb has a new command, "debug", which lets you step through
  arbitrary code from the debugger's (pdb) prompt.

Tim Peters df875b99fc New private API function _PyInstance_Lookup. gc will use this to figure
out whether __del__ exists, without executing any Python-level code.

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.

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.

Raymond Hettinger 1da1dbf458 Renamed PyObject_GenericGetIter to PyObject_SelfIter
to more accurately describe what the function does.

Suggested by Thomas Wouters.
2003-03-17 19:46:11 +00:00
Raymond Hettinger 0153826964 Created PyObject_GenericGetIter().
Factors out the common case of returning self.
2003-03-17 08:24:35 +00:00
Guido van Rossum e5c691abe3 - The extended type structure used for heap types (new-style
classes defined by Python code using a class statement) is now
  exported from object.h as PyHeapTypeObject.  (SF patch #696193.)
2003-03-07 15:13:17 +00:00
Neal Norwitz 1930949a8a Fix SF bug #697256, PyMarshal_WriteShortToFile() documented, but not implemented
Remove prototype and doc.  Backport candidate.
2003-03-06 22:04:24 +00:00
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).
2003-02-28 12:51:18 +00:00
Raymond Hettinger a72e2f9d10 Fix spelling and grammar. 2003-02-28 05:11:03 +00:00
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 *
instead of a plain PyObject *.  (SF patch #686601 by Ben Laurie.)
2003-02-19 15:53:17 +00:00
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.)
