Neal Norwitz 7b8e35ed7d Fix SF #639945, 64-bit bug on AIX
I can't test this on the snake farm (no aix box is working).
This change works for the submitter seems correct.
Can anybody test this on 32- and 64- bit AIX?

Neal Norwitz c91ed400e0 SF #561244, Micro optimizations
Initialize the small integers and __builtins__ in startup.
This removes some if conditions.
Change XDECREF to DECREF for values which shouldn't be NULL.

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.

Raymond Hettinger ea3fdf44a2 SF patch #659536: Use PyArg_UnpackTuple where possible.
Obtain cleaner coding and a system wide
performance boost by using the fast, pre-parsed
PyArg_Unpack function instead of PyArg_ParseTuple
function which is driven by a format string.

Just van Rossum 8982595870 Backing out patch #642578 in anticipation of final acceptance of PEP 302. 2002-12-25 23:13:34 +00:00
Jack Jansen 0a116f3a29 Squashed compiler warnings by adding casts, making sure prototypes are in
scope and looking at types.

Walter Dörwald d9a6ad3beb Enhance issubclass() and PyObject_IsSubclass() so that a tuple is
supported as the second argument. This has the same meaning as
for isinstance(), i.e. issubclass(X, (A, B)) is equivalent
to issubclass(X, A) or issubclass(X, B). Compared to isinstance(),
this patch does not search the tuple recursively for classes, i.e.
any entry in the tuple that is not a class, will result in a
TypeError.

This closes SF patch #649608.

Michael W. Hudson 006c75265f This is Richie Hindle's patch:
[ 631276 ] Exceptions raised by line trace function

It conflicted with the patches from Armin I just checked it, so I had
to so some bits by hand.

These are forward ports from 2.2.2.
2002-11-08 12:53:11 +00:00
Jack Jansen dde800ec4e Got rid of the python.rsrc resource file. The error message strings and
dialogs are now stored in Mac/Lib, and loaded on demand through macresource.
Not only does this simplify a MacPython based on Apple's Python, but
it also makes Mac error codes come out symbolically when running command
line python (if you have Mac/Lib in your path).

The resource files are copied from Mac/Resources. The old ones will disappear
after the OS9 build procedure has been adjusted.

Michael W. Hudson ca803a0dd7 One last tweak to the tracing machinery: this actually computes what I intended
all along.  Before instr_lb tended to be too high.

I don't think this actually makes any difference, given what the compiler

Guido van Rossum 98b2a42bc4 Fix SF bug 610610 (reported by Martijn Pieters, diagnosed by Neal Norwitz).
The switch in Exception__str__ didn't clear the error if
PySequence_Size() raised an exception.  Added a case -1 which clears
the error and falls through to the default case.

Definite backport candidate (this dates all the way to Python 2.0).
2002-09-18 04:06:32 +00:00
Michael W. Hudson 02ff6a9952 A slight change to SET_LINENO-less tracing.

Guido van Rossum 602d45194c Add a custom __str__ method to KeyError that applies repr() to the
missing key.  (Also added a guard to SyntaxError__str__ to prevent
calling PyString_Check(NULL).)
2002-09-03 20:24:09 +00:00
Skip Montanaro 99dba27e9a Bump default check interval to 100 instructions. Computers are much faster
than when this interval was first established.  Checking too frequently just
adds needless overhead because most of the time there is nothing to do and
no other threads ready to run.
2002-09-03 20:19:06 +00:00
Skip Montanaro d581d7792b replace thread state objects' ticker and checkinterval fields with two
globals, _Py_Ticker and _Py_CheckInterval.  This also implements Jeremy's
shortcut in Py_AddPendingCall that zeroes out _Py_Ticker.  This allows the
test in the main loop to only test a single value.

Guido van Rossum f689492070 Because MWH changed the bytecode again, moved the magic number *back*
to 62011.  This should get the snake-farm to throw away its old .pyc
files, amongst others.
2002-08-31 15:16:14 +00:00
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
trace function.  This removes the need for the RETURN_NONE opcode, so
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...
2002-08-30 13:09:51 +00:00

Guido van Rossum 86c659a329 The error messages in err_args() -- which is only called when the

Guido van Rossum d8dbf847b6 Add a warning comment to the LOAD_GLOBAL inline code. 2002-08-19 21:17:53 +00:00
Guido van Rossum 3a4dfc87e6 Another ugly inlining hack, expanding the two PyDict_GetItem() calls
in LOAD_GLOBAL.  Besides saving a C function call, it saves checks
whether f_globals and f_builtins are dicts, and extracting and testing
the string object's hash code is done only once.  We bail out of the
inlining if the name is not exactly a string, or when its hash is -1;
because of interning, neither should ever happen.  I believe interning
guarantees that the hash code is set, and I believe that the 'names'
tuple of a code object always contains interned strings, but I'm not
assuming that -- I'm simply testing hash != -1.

On my home machine, this makes a pystone variant with new-style
classes and slots run at the same speed as classic pystone!  (With
new-style classes but without slots, it is still a lot slower.)
2002-08-19 20:24:07 +00:00
Jeremy Hylton 192690e2d2 Inline fast_cfunction() in new call_function().
Also, don't handle METH_OLDARGS on the fast path.  All the interesting
builtins have been converted to use METH_NOARGS, METH_O, or
METH_VARARGS.

Result is another 1-2% speedup.  If I can cobble together 10 of these,
it might make a difference.
2002-08-16 18:36:11 +00:00
Jeremy Hylton e8c0432403 Move body of CALL_FUNCTION opcode into helper function.
This makes the code much easier to ready, because it is at a sane
indentation level.  On my box this shows a 1-2% speedup, which means
nothing, except that I'm not going to worry about the performance
effects of the change.
2002-08-16 17:47:26 +00:00
Guido van Rossum c13f724af0 Streamline the fast track for CFunction calls a bit more: there was
nothing special done if keyword arguments were present, so test for
that earlier and fall through to the normal case if there are any.
This ought to slow down CFunction calls with keyword args, but I don't
care; it's a tiny (1%) improvement for pystone.
2002-08-16 16:14:00 +00:00
Guido van Rossum c7903a13d2 A nice little speed-up for filter():
- Use PyObject_Call() instead of PyEval_CallObject(), saves several
  layers of calls and checks.

- Pre-allocate the argument tuple rather than calling Py_BuildValue()
  each time round the loop.

- For filter(None, seq), avoid an INCREF and a DECREF.
2002-08-16 07:04:56 +00:00
Guido van Rossum b7164621fa Add warnings for arguments named None. All set. (I could add a
warning for 'global None', but that's either accompanied by an

case it's harmless. :-)
2002-08-16 02:48:11 +00:00
Guido van Rossum 63dd79ac04 Add warning for None used as keyword argument name in function call.

Guido van Rossum b081e0c74c Minor cleanup of parsename() and parsestr(): the 'struct compiling *'

it's used.

Marc-André Lemburg cc8764ca9d Add C API PyUnicode_FromOrdinal() which exposes unichr() at C level.
u'%c' will now raise a ValueError in case the argument is an

2002-08-11 12:23:04 +00:00
Guido van Rossum 078151da90 Implement stage B0 of PEP 237: add warnings for operations that
currently return inconsistent results for ints and longs; in
particular: hex/oct/%u/%o/%x/%X of negative short ints, and x<<n that
either loses bits or changes sign.  (No warnings for repr() of a long,
though that will also change to lose the trailing 'L' eventually.)

This introduces some warnings in the test suite; I'll take care of
those later.

allocations small enough for PyMalloc to be a win have been
changed, which are:-
 - Python/compile.c
 - Parser/acceler.c
 - Parser/node.c
 - Parser/parsetok.c

This augments the aggressive overallocation strategy implemented by
Tim Peters in PyNode_AddChild() [Parser/node.c], in reducing the
impact of platform malloc()/realloc()/free() corner case behaviour.
Such corner cases are known to be triggered by test_longexp and
test_import.

Jeremy Hylton, in accepting this patch, recommended this as a
bugfix candidate for 2.2.  While the changes to Python/compile.c
and Parser/node.c backport easily (and could go in), the changes
to Parser/acceler.c and Parser/parsetok.c require other not
insignificant changes as a result of the differences in the memory
APIs between 2.3 and 2.2, which I'm not in a position to work
through at the moment.  This is a pity, as the Parser/parsetok.c
changes are the most important after the Parser/node.c changes, due
to the size of the memory requests involved and their frequency.

Jack Jansen 21ed16acbe Added one call to Py_Main(), for OSX framework builds only, that will get the
actual script to run in case we are running from an applet. If we are indeed
running an applet we skip the normal option processing leaving it all to the
applet code.

This allows us to get use the normal python binary in the Python.app bundle,
giving us all the normal command line options through PythonLauncher while
still allowing Python.app to be used as the template for building applets.

Consequently, pythonforbundle is gone, and Mac/Python/macmain.c isn't used
on OSX anymore.

Skip Montanaro 21ee37c94e remove spurious SET_LINENO from com_list_for and com_list_if. All they do
is slow things down unnecessarily and make tracing much more verbose.
Something like

    def f(n):
	return [i for i in range(n) if i%2]

should have at most two SET_LINENO instructions, not four.  When tracing,
the current line number should be printed once, not 2*n+1 times.

Tim Peters 0c32279626 Removed more stray instances of statichere, but left _sre.c alone. 2002-07-17 16:49:03 +00:00
Jeremy Hylton 938ace69a0 staticforward bites the dust.
The staticforward define was needed to support certain broken C
compilers (notably SCO ODT 3.0, perhaps early AIX as well) botched the
static keyword when it was used with a forward declaration of a static
initialized structure.  Standard C allows the forward declaration with
static, and we've decided to stop catering to broken C compilers.  (In
fact, we expect that the compilers are all fixed eight years later.)

I'm leaving staticforward and statichere defined in object.h as
static.  This is only for backwards compatibility with C extensions
that might still use it.

XXX I haven't updated the documentation.

Tim Peters 7c321a80f9 The Py_REF_DEBUG/COUNT_ALLOCS/Py_TRACE_REFS macro minefield: added
more trivial lexical helper macros so that uses of these guys expand
to nothing at all when they're not enabled.  This should help sub-
standard compilers that can't do a good job of optimizing away the
previous "(void)0" expressions.

Py_DECREF:  There's only one definition of this now.  Yay!  That
was that last one in the family defined multiple times in an #ifdef
maze.

Py_FatalError():  Changed the char* signature to const char*.

_Py_NegativeRefcount():  New helper function for the Py_REF_DEBUG
expansion of Py_DECREF.  Calling an external function cuts down on
the volume of generated code.  The previous inline expansion of abort()
didn't work as intended on Windows (the program often kept going, and
the error msg scrolled off the screen unseen).  _Py_NegativeRefcount
calls Py_FatalError instead, which captures our best knowledge of
how to abort effectively across platforms.

sys_gettotalrefcount():  Changed to enable under Py_REF_DEBUG.
It was enabled under Py_TRACE_REFS, which was much heavier than
necessary.  sys.gettotalrefcount() is now available in a
Py_REF_DEBUG-only build.

anything that is not a str). The unicode name is

Guido van Rossum bea18ccde6 SF patch 568629 by Oren Tirosh: types made callable.
These built-in functions are replaced by their (now callable) type:

    slice()
    buffer()

and these types can also be called (but have no built-in named
function named after them)

    classobj (type name used to be "class")
    code
    function
    instance
    instancemethod (type name used to be "instance method")

The module "new" has been replaced with a small backward compatibility
placeholder in Python.

A large portion of the patch simply removes the new module from
various platform-specific build recipes.  The following binary Mac
project files still have references to it:

    Mac/Build/PythonCore.mcp
    Mac/Build/PythonStandSmall.mcp
    Mac/Build/PythonStandalone.mcp

[I've tweaked the code layout and the doc strings here and there, and
added a comment to types.py about StringTypes vs. basestring.  --Guido]

Guido van Rossum c5fe5eb8d2 SF bug 567538: Generator can crash the interpreter (Finn Bock).
This was a simple typo.  Strange that the compiler didn't catch it!
Instead of WHY_CONTINUE, two tests used CONTINUE_LOOP, which isn't a
why_code at all, but an opcode; but even though 'why' is declared as
an enum, comparing it to an int is apparently not even worth a
warning -- not in gcc, and not in VC++. :-(

Will fix in 2.2 too.

Tim Peters 5de9842b34 Repair widespread misuse of _PyString_Resize. Since it's clear people
don't understand how this function works, also beefed up the docs.  The
most common usage error is of this form (often spread out across gotos):

	if (_PyString_Resize(&s, n) < 0) {
		Py_DECREF(s);
		s = NULL;
		goto outtahere;
	}

The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL.  So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s):  s is already
NULL!  A correct way to write the above is the simpler (and intended)

	if (_PyString_Resize(&s, n) < 0)
		goto outtahere;

Bugfix candidate.

Jeremy Hylton 1b0bf9b761 Ignore SIGXFSZ.
The SIGXFSZ signal is sent when the maximum file size limit is
exceeded (RLIMIT_FSIZE).  Apparently, it is also sent when the 2GB
file limit is reached on platforms without large file support.

The default action for SIGXFSZ is to terminate the process and dump
core.  When it is ignored, the system call that caused the limit to be
exceeded returns an error and sets errno to EFBIG.  Python
always checks errno on I/O syscalls, so there is nothing to do with
the signal.

Tim Peters 51e7f5caba Moving pymalloc along.
+ Redirect PyMem_{Del, DEL} to the object allocator's free() when
  pymalloc is enabled.  Needed so old extensions can continue to
  mix PyObject_New with PyMem_DEL.

+ This implies that pgen needs to be able to see the PyObject_XYZ
  declarations too.  pgenheaders.h now includes Python.h.  An
  implication is that I expect obmalloc.o needs to get linked into
  pgen on non-Windows boxes.

+ When PYMALLOC_DEBUG is defined, *all* Py memory API functions
  now funnel through the debug allocator wrapper around pymalloc.
  This is the default in a debug build.

+ That caused compile.c to fail:  it indirectly mixed PyMem_Malloc
  with raw platform free() in one place.  This is verbotten.
