Jeremy Hylton 6b4ec5135b Fix for SF bug #117241
When a method is called with no regular arguments and * args, defer
the first arg is subclass check until after the * args have been
expanded.

N.B. The CALL_FUNCTION implementation is getting really hairy; should
review it to see if it can be simplified.

Fred Drake 661ea26b3d Ka-Ping Yee <ping@lfw.org>:
Changes to error messages to increase consistency & clarity.

This (mostly) closes SourceForge patch #101839.

Thomas Wouters 0be483fd4d Do a better job at staying on-screen :P (Sorry, it's late here.) I'm
assuming here that the ANSI-C adjacent-string-concatenation technique is
allowable, now that Python requires an ANSI C compiler.

Thomas Wouters 8fb62a2e9a Adjust debugging code in the implementation of the DUP_TOPX bytecode, use
Py_FatalError() instead, and clarify the message somewhat. As discussed on
python-dev.
2000-10-11 23:20:09 +00:00
Fred Drake 48fba733b9 Remove the last gcc -Wall warning about possible use of an uninitialized
variable.  w should be initialized before entering the bytecode
interpretation loop since we only need one initialization to satisfy the
compiler.
2000-10-11 13:54:07 +00:00
Tim Peters 35ba689cab Attempt to fix bogus gcc -Wall warnings reported by Marc-Andre Lemburg,
by making the DUP_TOPX code utterly straightforward.  This also gets rid
of all normal-case internal DUP_TOPX if/branches, and allows replacing one
POP() with TOP() in each case, so is a good idea regardless.

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
Marc-André Lemburg d1ba443206 This patch adds a new Python C API called PyString_AsStringAndSize()
which implements the automatic conversion from Unicode to a string
object using the default encoding.

The new API is then put to use to have eval() and exec accept
Unicode objects as code parameter. This closes bugs #110924
and #113890.

As side-effect, the traditional C APIs PyString_Size() and
PyString_AsString() will also accept Unicode objects as
parameters.

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.
This should match the situation in the 1.6b1 tree.

Tim Peters d320c348f8 Revert removal of void from function definition. Guido sez I can take it
out again after we complete switching to C++ <wink>.  Thanks to Greg Stein
for hitting me.
2000-09-01 03:34:26 +00:00
Guido van Rossum 349ff6f7e2 Set the recursion limit to 1000 -- 2500 was not enough, let's be
conservative.
2000-09-01 01:52:08 +00:00
Tim Peters 51de6906be Supply missing prototypes for new Py_{Get,Set}RecursionLimit; fixes compiler wngs;
un-analize Get's definition ("void" is needed only in declarations, not defns, &
is generally considered bad style in the latter).
2000-09-01 00:01:58 +00:00
Jeremy Hylton ee5adfbae6 add user-modifiable recursion_limit
ceval.c:
    define recurion_limit (static), default value is 2500
    define Py_GetRecursionLimit and Py_SetRecursionLimit
    raise RuntimeError if limit is exceeded
PC/config.h:
    remove plat-specific definition
sysmodule.c:
    add sys.(get|set)recursionlimit

Paul Prescod e68140dd3c Better error message with UnboundLocalError 2000-08-30 20:25:01 +00:00
Barry Warsaw 093abe005d eval_code2(): Guido provides this patch for his suggested elaboration
of extended print.  If the file object being printed to is None, then
sys.stdout is used.

Thomas Wouters dd13e4f91f Replace the run-time 'future-bytecode-stream-inspection' hack to find out
how 'import' was called with a compiletime mechanism: create either a tuple
of the import arguments, or None (in the case of a normal import), add it to
the code-block constants, and load it onto the stack before calling
IMPORT_NAME.
2000-08-27 20:31:27 +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)

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
Barry Warsaw 23c9ec87cf PEP 214, Extended print Statement, has been accepted by the BDFL.
eval_code2(): Implement new bytecodes PRINT_ITEM_TO and
PRINT_NEWLINE_TO, as per accepted SF patch #100970.

Also update graminit.c based on related Grammar/Grammar changes.
2000-08-21 15:44:01 +00:00
Thomas Wouters 0400515ff0 Fix the bug Sjoerd Mullender discovered, where find_from_args() wasn't
trying hard enough to find out what the arguments to an import were. There
is no test-case for this bug, yet, but this is what it looked like:

from encodings import cp1006, cp1026
ImportError: cannot import name cp1026

'__import__' was called with only the first name in the 'arguments' list.

Fred Drake 04e654a63c Remove a couple of warnings turned up by "gcc -Wall". 2000-08-18 19:53:25 +00:00
Thomas Wouters 5215225ea1 Apply SF patch #101135, adding 'import module as m' and 'from module import
name as n'. By doing some twists and turns, "as" is not a reserved word.

There is a slight change in semantics for 'from module import name' (it will
now honour the 'global' keyword) but only in cases that are explicitly
undocumented.
2000-08-17 22:55:00 +00:00
Thomas Wouters 0be5aab04d Merge UNPACK_LIST and UNPACK_TUPLE into a single UNPACK_SEQUENCE, since they
did the same anyway.

I'm not sure what to do with Tools/compiler/compiler/* -- that isn't part of
distutils, is it ? Should it try to be compatible with old bytecode version ?

Moshe Zadka aa39a7edf7 Initialized opcode and oparg to silence a gcc -Wall warning. 2000-08-07 06:34:45 +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
Thomas Wouters f70ef4f860 Mass ANSIfication of function definitions. Doesn't cover all 'extern'
declarations yet, those come later.
2000-07-22 18:47:25 +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 ;)

Jack Jansen cbf630f0a9 Include macglue.h for some function prototypes, and renamed a few
mac-specific functions to have a PyMac_ name.

Guido van Rossum 582acece2e Trent Mick's Win64 changes: size_t vs. int or long; also some overflow
tests.

Guido van Rossum 20c6add7ff Trent Mick:
Change static slice_index() to extern _PyEval_SliceIndex() (with
different return value interpretation: 0 for failure, 1 for success).
2000-05-08 14:06:50 +00:00
Guido van Rossum cc229ea76f Add useless 'return 1' to prtrace() to shut up VC++. 2000-05-04 00:55:17 +00:00
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 25826c93c4 Charles Waldman writes:
"""
Running "test_extcall" repeatedly results in memory leaks.

One of these can't be fixed (at least not easily!), it happens since
this code:

def saboteur(**kw):
    kw['x'] = locals()
d = {}
saboteur(a=1, **d)

creates a circular reference - d['x']['d']==d

The others are due to some missing decrefs in ceval.c, fixed by the
patch attached below.

Note:  I originally wrote this without the "goto", just adding the
missing decref's where needed.  But I think the goto is justified in
keeping the executable code size of ceval as small as possible.
"""

[I think the circular reference is more like kw['x']['kw'] == kw. --GvR]

Guido van Rossum 5db862dd0c Skip Montanaro: add string precisions to calls to PyErr_Format

Jeremy Hylton 074c3e62d1 Two fixes for extended call syntax:
If a non-tuple sequence is passed as the *arg, convert it to a tuple
before checking its length.
If named keyword arguments are used in combination with **kwargs, make
a copy of kwargs before inserting the new keys.
2000-03-30 23:55:31 +00:00
Barry Warsaw b2ba9d8963 eval_code2(): Oops, in the last checkin, we shouldn't check for
PyErr_Occurred(), just set x=NULL and break.  Oh, and make Jeremy stop
nagging me about the "special" indentation for this block.
2000-03-29 18:36:49 +00:00
Barry Warsaw 4961ef7086 eval_code2(): In the extended calling syntax opcodes, you must check
the return value of PySequence_Length().  If an exception occurred,
the returned length will be -1.  Make sure this doesn't get obscurred,
and that the bogus length isn't used.
2000-03-29 18:30:03 +00:00
Jeremy Hylton 7690151c7e slightly modified version of Greg Ewing's extended call syntax patch
executive summary:
Instead of typing 'apply(f, args, kwargs)' you can type 'f(*arg, **kwargs)'.
Some file-by-file details follow.

Grammar/Grammar:
    simplify varargslist, replacing '*' '*' with '**'
    add * & ** options to arglist

Include/opcode.h & Lib/dis.py:
    define three new opcodes
        CALL_FUNCTION_VAR
        CALL_FUNCTION_KW
        CALL_FUNCTION_VAR_KW

Python/ceval.c:
    extend TypeError "keyword parameter redefined" message to include
        the name of the offending keyword
    reindent CALL_FUNCTION using four spaces
    add handling of sequences and dictionaries using extend calls
    fix function import_from to use PyErr_Format

Guido van Rossum a400d8a96d Fix a bug in exec_statement() noted incidentally by Tim Peters in
PR#175 -- when exec is passed a code object, it didn't sync the locals
from the dictionary back into their fast representation.

Also took the time to remove some repetitive code there and to do the
syncing even when an exception is raised (since a partial effect
should still be synced).

Guido van Rossum ba98a42a0f Change the last PyErr_Format %s format to %.400s. 1999-11-15 19:29:33 +00:00
Guido van Rossum 25da5bebd8 Fix PR117. The error message is "keywords must be strings". Perhaps
not as descriptive as what Barry suggests, but this also catches the
(in my opinion important) case where some other C code besides apply()
constructs a kwdict that doesn't have the right format.  All the other
possibilities of getting it wrong (non-dict, wrong keywords etc) are
already caught so this makes sense to check here.
