Martin v. Löwis dfc33fd8db Don't use Posix semaphores on Solaris 8. Fixes #662787. 2003-01-21 10:14:41 +00:00
Raymond Hettinger 4bad9ba282 SF patch #670367: Micro-optimizations for ceval.c
Make the code slightly shorter, faster, and easier to
read.

* Eliminate unused DUP_TOPX code for x==1.
compile.c always generates DUP_TOP instead.

* Since only two cases remain for DUP_TOPX, replace
the switch-case with if-elseif.

* The in-lined integer compare does a CheckExact on
both arguments. Since the second is a little more
likely to fail, test it first.

* The switch-case for IS/IS_NOT and IN/NOT_IN can
separate the regular and inverted cases with no
additional work. For all four paths, saves a test and
jump.

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.

Michael W. Hudson 976249be74 A. Lloyd Flanagan pointed out a spelling error on c.l.py. 2003-01-16 15:39:07 +00:00
Raymond Hettinger 8bb90a59a6 Replaced POP() with STACKADJ(-1) on lines where the result wasn't used.
The two are semantically equivalent, but the first triggered a compiler
warning about an unused variable.  Note, the preceding steps had already
accessed and decreffed the variable so the reference counts were fine.

Raymond Hettinger 71731d7f70 As discussed on python-dev, removed from DUP_TOPX support for the
parameter being either four or five.  Currently, compile.c does not
generate calls with a parameter higher than three.

May have to be reverted if the second alpha or beta shakes out some
other tool generating this op code with a parameter of four or five.

Neal Norwitz 37aa066164 As discussed briefly on python-dev, add Pending Deprecation Warning

is deprecated in an exception message.

Raymond Hettinger 663004bb3d SF patch #664320: Replace push/pop clusters in ceval.c
Replaced groups of pushes and pops with indexed access to the stack and
a single adjustment (if needed) to the stacklevel.

Avoids scores of unnecessary increments and decrements to the stackpointer.
Removes unnecessary sequential dependencies so that the compiler has more
freedom for optimizations.  Frees the processor for more parallel and
pipelined execution by using mostly read-only access and having few pointer
adjustments just prior to a read or write.

Thomas Heller 27bb71e963 Patch #664376: sys.path[0] should contain absolute pathname.
This fixes the problem on Windows - that's the only system where I can
test it.

It leaves sys.argv alone and only changes sys.path[0] to an absolute
pathname.

Jeremy Hylton accb62b28e SF patch [ 597919 ] compiler package and SET_LINENO
A variety of changes from Michael Hudson to get the compiler working
with 2.3.  The primary change is the handling of SET_LINENO:

# The set_lineno() function and the explicit emit() calls for
# SET_LINENO below are only used to generate the line number table.
# As of Python 2.3, the interpreter does not have a SET_LINENO
# instruction.  pyassem treats SET_LINENO opcodes as a special case.

A few other small changes:
 - Remove unused code from pycodegen and pyassem.
 - Fix error handling in parsermodule.  When PyParser_SimplerParseString()
   fails, it sets an exception with detailed info.  The parsermodule
   was clobbering that exception and replacing it was a generic
   "could not parse string" exception.  Keep the original exception.

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.

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.

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.

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.

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 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.

Guido van Rossum b081e0c74c Minor cleanup of parsename() and parsestr(): the 'struct compiling *'
argument should be called 'c', like everywhere else.  Renamed a
complex variable 'c' to 'z' and moved it inside the only scope where
it's used.

Fred Drake 233cc5987b Py_InitModule4(): Accept NULL for the 'methods' argument. This makes
sense now that extension types can support __init__ directly rather

a lot of work, including I/O (e.g. to import warnings.py), which might
affect errno.
