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.)

Neal Norwitz 2294c0d4ec Cleanup from patch #683257:
Add missing INCREFs and re-indent returns to be consistent.
 Add \n\ for lines in docstring
 Add a pathetic test
 Add docs

Guido van Rossum c4f4ca91e1 Provide access to the import lock, fixing SF bug #580952. This is
mostly from SF patch #683257, but I had to change unlock_import() to
return an error value to avoid fatal error.

Should this be backported?  The patch requested this, but it's a new
feature.

Guido van Rossum 66b1259dbc SF #660455 : patch by NNorwitz.
"Unsigned" (i.e., positive-looking, but really negative) hex/oct
constants with a leading minus sign are once again properly negated.
The micro-optimization for negated numeric constants did the wrong
thing for such hex/oct constants.  The patch avoids the optimization
for all hex/oct constants.

This needs to be backported to Python 2.2!

Walter Dörwald 8dd19321bb Change filtertuple() to use tp_as_sequence->sq_item
instead of PyTuple_GetItem, so an overwritten __getitem__
in a tuple subclass works. SF bug #665835.

Tim Peters 2c646c9fc1 Squashed compiler wng about signed/unsigned clash in comparison. 2003-02-10 14:48:29 +00:00
Walter Dörwald 1918f7755e Change filterstring() and filterunicode(): If the
object is not a real str or unicode but an instance
of a subclass, construct the output via looping
over __getitem__. This guarantees that the result
is the same for function==None and function==lambda x:x

This doesn't happen for tuples, because filtertuple()
uses PyTuple_GetItem().

(This was discussed on SF bug #665835).

Just van Rossum b9b8e9cf6d My previous checkin caused compile() to no longer accept buffers, as noted
my MAL. Fixed. (Btw. eval() still doesn't take buffers, but that was so
even before my patch.)

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.

Neil Schemenauer 5042da6b1e If a float is passed where a int is expected, issue a DeprecationWarning

Walter Dörwald 531e000d2e PyUnicode_Resize() doesn't free its argument in case of a failure,
so we can jump to the error handling code that does.

Walter Dörwald 903f1e0c40 filterstring() and filterunicode() in Python/bltinmodule.c
blindly assumed that tp_as_sequence->sq_item always returns
a str or unicode object. This might fail with str or unicode
subclasses.

This patch checks whether the object returned from __getitem__
is a str/unicode object and raises a TypeError if not (and
the filter function returned true).

Furthermore the result for __getitem__ can be more than one
character long, so checks for enough memory have to be done.

Neal Norwitz 94c30c0124 SF #661437, apply() should get PendingDeprecation 2003-02-03 20:23:33 +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.

Neil Schemenauer b808e99d34 Raise a TypeError if a float is passed when an integer is specified.
Calling PyInt_AsLong() on a float truncates it which is almost never
the desired behavior.  This closes SF bug #660144.

Jack Jansen a038270590 MacPython-OS9 has had an abort() function for quite a while now, so there's no reason to stall in an endless loop, just call abort() on a fatal error. 2003-01-24 16:17:18 +00:00
Jack Jansen 9363dca3f8 MacPython-OS9 specific fix: If there are non-string items on sys.path don't try to intern them. This has the theoretical problem that resource filenames on sys.path cannot be unicode objects, but in practice that shouldn't matter. 2003-01-24 16:15:45 +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.
2003-01-14 12:43:10 +00:00
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

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.
