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.

Neal Norwitz dee2fd5448 Fix some more memory leaks.
Call error_ret() in decode_str().  It was called in some other places,
but seemed inconsistent.  It is safe to call PyTokenizer_Free() after
calling error_ret().

Jeremy Hylton 3e0055f8c6 Merge ast-branch to head
This change implements a new bytecode compiler, based on a
transformation of the parse tree to an abstract syntax defined in
Parser/Python.asdl.

The compiler implementation is not complete, but it is in stable
enough shape to run the entire test suite excepting two disabled
tests.

Michael W. Hudson e3afc598bc In a threads-disabled build, typing Ctrl-C into a raw_input() crashed,
because (essentially) I didn't realise that PY_BEGIN/END_ALLOW_THREADS
actually expanded to nothing under a no-threads build, so if you somehow
NULLed out the threadstate (e.g. by calling PyThread_SaveThread) it would
stay NULLed when you return to Python.  Argh!

Backport candidate.

[ 960406 ] unblock signals in threads

although the changes do not correspond exactly to any patch attached to
that report.

Non-main threads no longer have all signals masked.

A different interface to readline is used.

The handling of signals inside calls to PyOS_Readline is now rather
different.

These changes are all a bit scary!  Review and cross-platform testing
much appreciated.

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.)

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).

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.

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())

Guido van Rossum b09f7ed623 Preliminary support for "from __future__ import generators" to enable

this.

Guido van Rossum 48a680c097 RISCOS changes by dschwertberger. 2001-03-02 06:34:14 +00:00
Neil Schemenauer 84521c078e Take output filenames as arguments instead of hard-coding them. 2001-02-16 03:57:53 +00:00
Neil Schemenauer 693291ba23 Superseded by $(srcdir)/Makefile.pre.in. 2001-02-03 17:18:21 +00:00
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.)

Tim Peters 1d6a7297d3 More limits.h stuff in node.c.
Fred, check this!
2000-09-26 06:11:54 +00:00
Fred Drake d5fadf75e4 Rationalize use of limits.h, moving the inclusion to Python.h.
Add definitions of INT_MAX and LONG_MAX to pyport.h.
Remove includes of limits.h and conditional definitions of INT_MAX
and LONG_MAX elsewhere.

This closes SourceForge patch #101659 and bug #115323.
2000-09-26 05:46:01 +00:00
Vladimir Marangozov 58e64a82ee Move down the INT_MAX logic, because HAVE_LIMITS_H was always undefined
and this breaks the AIX build with an INT_MAX redefinition error.
"config.h" is included in pgenheaders.h, so moving this down fixes the
problem.
2000-09-03 23:47:08 +00:00
Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.
This should match the situation in the 1.6b1 tree.
2000-09-01 23:29:29 +00:00
Fred Drake dd19eaf966 Added a little more dependency information. 2000-08-31 05:11:48 +00:00
Guido van Rossum fee3a2dd8c Charles Waldman's patch to reinitialize the interpreter lock after a
fork.  This solves the test_fork1 problem.  (ceval.c, signalmodule.c,
intrcheck.c)

SourceForge: [ Patch #101226 ] make threading fork-safe
2000-08-27 17:34:07 +00:00
Thomas Wouters 434d0828d8 Support for three-token characters (**=, >>=, <<=) which was written by
Michael Hudson, and support in general for the augmented assignment syntax.
The graminit.c patch is large!
2000-08-24 20:11:32 +00:00
Fred Drake ef8ace3a6f Charles G. Waldman <cgw@fnal.gov>:
Add the EXTENDED_ARG opcode to the virtual machine, allowing 32-bit
arguments to opcodes instead of being forced to stick to the 16-bit
limit.  This is especially useful for machine-generated code, which
can be too long for the SET_LINENO parameter to fit into 16 bits.

This closes the implementation portion of SourceForge patch #100893.
2000-08-24 00:32:09 +00:00
Fred Drake eb375e49f5 Simplified inclusions and avoid prototypes copied in from elsewhere.
This also avoids a warning in anal mode.
2000-08-23 18:17:42 +00:00
Barry Warsaw 38aa14afb6 PyParser_ParseString(): When the err_ret structure is initialized, the
fields token and expected must also be initialized, otherwise the
tests in parsetok() can generate uninitialized memory read errors.
This quiets an Insure warning.
2000-08-18 05:04:08 +00:00
Peter Schneider-Kamp 7e01890986 merge Include/my*.h into Include/pyport.h
marked my*.h as obsolete
2000-07-31 15:28:04 +00:00
Thomas Wouters 334fb8985b Use 'void' directly instead of the ANY #define, now that all code is ANSI C.
Leave the actual #define in for API compatibility.
2000-07-25 12:56:38 +00:00
Tim Peters 4f1b2081e9 Removed all instances of RETSIGTYPE from the source code: signal
handlers "return void", according to ANSI C.
Removed the new Py_RETURN_FROM_SIGNAL_HANDLER macro.
Left RETSIGTYPE in the config stuff, because it's not clear to
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
to worry about systems that have signal-handlers return 'int' ? Not all of
the code does, though nothing will break because of it.
2000-07-22 23:33:22 +00:00
Thomas Wouters 23c9e0024a Mass ANSIfication.
Work around intrcheck.c's desire to pass 'PyErr_CheckSignals' to
'Py_AddPendingCall' by providing a (static) wrapper function that has the
right number of arguments.
2000-07-22 19:20:54 +00:00
Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either
comments, docstrings or error messages. I fixed two minor things in
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 ;)
2000-07-16 12:04:32 +00:00
Fred Drake 85f363990c Create two new exceptions: IndentationError and TabError. These are
used for indentation related errors.  This patch includes Ping's
improvements for indentation-related error messages.

Closes SourceForge patches #100734 and #100856.

Jeremy Hylton 94988067b9 Add new parser error code, E_OVERFLOW. This error is returned when
the number of children of a node exceeds the max possible value for
the short that is used to count them.  The Python runtime converts
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.)

1998-08-29 16:03:27 +00:00
Guido van Rossum 8efa47b63e We now assume that PyOS_Readline() is called with the interpreter lock
held.  It releases the lock around the call to the function pointed to by
PyOS_ReadlineFunctionPointer (default PyOS_StdioReadline()).
1998-08-27 19:43:43 +00:00
Guido van Rossum 6e73bf4032 Replace all calls to fprintf(stderr, ...) with PySys_WriteStderr(...). 1998-08-25 18:13:04 +00:00
Guido van Rossum 47fbc4049e Add a version of PySys_WriteStderr() that writes to stderr, so we can
use it in tokenizer.c.

Guido van Rossum 54758fa8ca Swap two statements in the dedent check loop. This makes absolutely
no difference, but avoids triggering an optimizer bug in the AIX
compiler where the loop unrolling does the wrong thing...
1998-02-16 22:18:00 +00:00
Guido van Rossum 35685240a9 Fixed the bug in searching for triple quotes -- change the 'quote2'
variable from a pointer to an index, so a realloc() of the buffer
won't disturb it.  Problem found by Vladimir Marangozov.
1998-02-16 15:42:50 +00:00
Guido van Rossum cf57d8b8c9 tok_nextc() should return unsigned characters, to avoid mistaking
'\377' for EOF.
1998-01-19 22:07:46 +00:00
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 44620646fd Renamed Py_input_hook to PyOS_InputHook.

Guido van Rossum aee094cc60 Added finalization routines. 1997-08-02 03:02:27 +00:00
Guido van Rossum ff0ec52d3c Finally plug the memory leak caused by syntax error (including
interactive EOF, which leaked *one* byte).
