Tim Peters 8ab2ec432a SF bug 751956: graminit.[ch] don't build on windows
A change from Duncan Booth, to deal with changes in the way pgen gets
built.  Note that graminit.[ch] aren't normally built on Windows (they're
obtained from CVS).

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.

Barry Warsaw edaa071eb4 compile_atom(): Neal's last checkin removing the setting of i broke
the build, so I'm restoring it.  I'm not sure what Neal's intent was,
since the line following the one he removed was "REQN(i, 1)" so i is
obviously used. ;)

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.)

Skip Montanaro 35f63a860b Change PyOS_Readline declaration to match the recent change to myreadline.c

be the correct course.  I don't know the code involved well enough to judge.

Guido van Rossum 84b2bed435 Squash a few calls to the hideously expensive PyObject_CallObject(o,a)
-- replace then with slightly faster PyObject_Call(o,a,NULL).  (The
difference is that the latter requires a to be a tuple; the former
allows other values and wraps them in a tuple if necessary; it
involves two more levels of C function calls to accomplish all that.)

Andrew MacIntyre 80d4e2acf5 SF patch #578297:
Change the parser and compiler to use PyMalloc.

Only the files implementing processes that will request memory
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.
2002-08-04 06:28:21 +00:00
Tim Peters e561dc231e XXXROUNDUP(): Turns out this fixed Andrew MacIntyre's memory-mgmt
disaster too, so this change is here to stay.  Beefed up the comments
and added some stats Andrew reported.  Also a small change to the
macro body, to make it obvious how XXXROUNDUP(0) ends up returning 0.
See SF patch 578297 for context.

Not a bugfix candidate, as the functional changes here have already
been backported to the 2.2 line (this patch just improves clarity).

Mark Hammond 2f10cb8fa5 Fix bug 439992 - [win32] KeyboardInterrupt Not Caught.

Thomas Heller 6b17abf6c0 Fix SF Bug 564931: compile() traceback must include filename. 2002-07-09 09:23:27 +00:00
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.

Tim Peters 623fdb9884 PyNode_AddChild() and fancy_roundup(): Be paranoid about int overflow. 2002-07-08 19:11:07 +00:00
Tim Peters 755ebea23b PyNode_AddChild(): Do aggressive over-allocation when the number of
children gets large, to avoid severe platform realloc() degeneration
in extreme cases (like test_longexp).

Bugfix candidate.

This was doing extremely timid over-allocation, just rounding up to the
nearest multiple of 3.  Now so long as the number of children is <= 128,
it rounds up to a multiple of 4 but via a much faster method.  When the
number of children exceeds 128, though, and more space is needed, it
doubles the capacity.  This is aggressive over-allocation.

SF patch <http://www.python.org/sf/578297> has Andrew MacIntyre using
PyMalloc in the parser to overcome platform malloc problems in
test_longexp on OS/2 EMX.  Jack Jansen notes there that it didn't help
him on the Mac, because the Mac has problems with frequent ever-growing
reallocs, not just with gazillions of teensy mallocs.  Win98 has no
visible problems with test_longexp, but I tried boosting the test-case
size and soon got "senseless" MemoryErrors out of it, and soon after
crashed the OS:  as I've seen in many other contexts before, while the
Win98 realloc remains zippy in bad cases, it leads to extreme
fragmentation of user address space, to the point that the OS barfs.

I don't yet know whether this fixes Jack's Mac problems, but it does cure
Win98's problems when boosting the test case size.  It also speeds
test_longexp in its unaltered state.

2001-08-27 19:19:28 +00:00
Guido van Rossum 4668b000a1 Implement PEP 238 in its (almost) full glory.
This introduces:

- A new operator // that means floor division (the kind of division
  where 1/2 is 0).

- The "future division" statement ("from __future__ import division)
  which changes the meaning of the / operator to implement "true
  division" (where 1/2 is 0.5).

- New overloadable operators __truediv__ and __floordiv__.

- New slots in the PyNumberMethods struct for true and floor division,
  new abstract APIs for them, new opcodes, and so on.

I emphasize that without the future division statement, the semantics
of / will remain unchanged until Python 3.0.

Not yet implemented are warnings (default off) when / is used with int
or long arguments.

This has been on display since 7/31 as SF patch #443474.

Flames to /dev/null.

2001-07-19 15:27:45 +00:00
Guido van Rossum da62ecc9aa Add a really stupid warning about 'yield' used as an identifier.
This is really stupid because it cannot be suppressed or altered using
the warning framework; that's because the warning framework is built
on Python interpreter internals, and the parser generator doesn't have
access to any of those (you cannot use anything of type PyObject * in
the parser).

But it's better than nothing, and implementing a proper check for this
appears to require modifying compile.c in a dozen places, for which I
don't have the stamina today.  I promise we'll do better in 2.2a2.

At least it tells you the filename and line number (unlike the first
hack I considered :-).
2001-07-17 16:53:11 +00:00
Tim Peters fe2127d3cb Ugly. A pile of new xxxFlags() functions, to communicate to the parser
that 'yield' is a keyword.  This doesn't help test_generators at all!  I
don't know why not.  These things do work now (and didn't before this
patch):

1. "from __future__ import generators" now works in a native shell.

2. Similarly "python -i xxx.py" now has generators enabled in the
   shell if xxx.py had them enabled.

3. This program (which was my doctest proxy) works fine:

from __future__ import generators

source = """\
def f():
    yield 1
"""

exec compile(source, "", "single") in globals()
print type(f())
2001-07-16 05:37:24 +00:00
Guido van Rossum b09f7ed623 Preliminary support for "from __future__ import generators" to enable
the yield statement.  I figure we have to have this in before I can
release 2.2a1 on Wednesday.

Note: test_generators is currently broken, I'm counting on Tim to fix
this.

Guido van Rossum e3c3b27d33 Fix a bug in stack overflow error handling. This fixes half of Bug
#115555.

The error from s_push() on stack overflow was -1, which was passed
through unchanged by push(), but not tested for by push()'s caller --
which only expected positive error codes.  Fixed by changing s_push()
to return E_NOMEM on stack overflow.  (Not quite the proper error code
either, but I can't be bothered adding a new E_STACKOVERFLOW error
code in all the right places.)

Removed the new Py_RETURN_FROM_SIGNAL_HANDLER macro.

me that others aren't relying on it (e.g., extension modules).
2000-07-23 21:18:09 +00:00
Tim Peters 1be46844d9 Recent ANSIfication introduced a couple instances of
#if RETSIGTYPE != void
That isn't C, and MSVC properly refuses to compile it.
Introduced new Py_RETURN_FROM_SIGNAL_HANDLER macro in pyport.h
to expand to the correct thing based on RETSIGTYPE.  However,
only void is ANSI!  Do we still have platforms that return int?
The Unix config mess appears to #define RETSIGTYPE by magic
without being asked to, so I assume it's "a problem" across
Unices still.
2000-07-23 18:10:18 +00:00
Thomas Wouters bd8ad942fe Remember to return something if RETSIGTYPE is not 'void'. Do we still need

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either

test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

this parser error into the SyntaxError "expression too long."

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Guido van Rossum 35685240a9 Fixed the bug in searching for triple quotes -- change the 'quote2'

Guido van Rossum 7bf22de753 Patch for QNX, by Chris Herborth. 1997-12-02 20:34:19 +00:00
Guido van Rossum 359bcaa539 This fix (across 4 files in 3 directories) solves a subtle problem with
signal handlers in a fork()ed child process when Python is compiled with
thread support.  The bug was reported by Scott <scott@chronis.icgroup.com>.

What happens is that after a fork(), the variables used by the signal
module to determine whether this is the main thread or not are bogus,
and it decides that no thread is the main thread, so no signals will
be delivered.

The solution is the addition of PyOS_AfterFork(), which fixes the signal
module's variables.  A dummy version of the function is present in the
intrcheck.c source file which is linked when the signal module is not
used.

Guido van Rossum fbd64c8790 Restructured quite a bit, hopefully Lee Busby will find this useful.
Also grandly renamed.

Here's the new interface:

When WITH_READLINE is defined, two functions are defined:

  - PyOS_GnuReadline (what used to be my_readline() with WITH_READLINE)
  - PyOS_ReadlineInit (for Dave Ascher)

Always, these functions are defined:

  - PyOS_StdioReadline (what used to be my_readline() without WITH_READLINE)
  - PyOS_Readline (the interface used by tokenizer.c and [raw_]input().

There's a global function pointer PyOS_ReadlineFunctionPointer,
initialized to NULL.  When PyOS_Readline finds this to be NULL, it
sets it to either PyOS_GnuReadline or PyOS_StdioReadline depending on
which one makes more sense (i.e. it uses GNU only if it is defined
*and* stdin is indeed a tty device).

An embedding program that has its own wishes can set the function
pointer to a function of its own design.  It should take a char*
prompt argument (which may be NULL) and return a string *ending in a
\n character* -- or "" for EOF or NULL for a user interrupt.
