Tim Peters eba84cdacb An MSVC makefile to rebuild the grammar files (graminit.[ch]) manually.
Ugly, but it works.

Guido van Rossum 25dfe2c095 Silence parser generator output. 2001-09-11 16:43:16 +00:00
Tim Peters d507dab91f SF patch #455966: Allow leading 0 in float/imag literals.
Consequences for Jython still unknown (but raised on Jython-Dev).

Tim Peters 9aa70d93aa SF bug [#455775] float parsing discrepancy.
PyTokenizer_Get:  error if exponent contains no digits (3e, 2.0e+, ...).

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.

Guido van Rossum 3c033230ec Fis SF bug #442647: not all forms of legal future statements were
parsed correctly.  Now they are.
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.)

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.

2000-08-24 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.

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 ;)

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 8efa47b63e We now assume that PyOS_Readline() is called with the interpreter lock

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

1998-02-16 15:42:50 +00:00
Guido van Rossum cf57d8b8c9 tok_nextc() should return unsigned characters, to avoid mistaking

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 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.
