Neal Norwitz 30b5c5d011 Fix SF bug #1072182, problems with signed characters. 
Most of these can be backported.
 2005-12-19 06:05:18 +00:00
Neal Norwitz db83eb3170 Fix Bug #1378022, UTF-8 files with a leading BOM crashed the interpreter. 
Needs backport.
 2005-12-18 05:29:30 +00:00
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().
 2005-11-16 05:12:59 +00:00
Neal Norwitz c0d5faa9b4 Free coding spec (cs) if there was an error to prevent mem leak. Maybe backport candidate 2005-10-21 06:05:33 +00:00
Neal Norwitz 40d3781416 - Fix segfault with invalid coding. 
- SF Bug #772896, unknown encoding results in MemoryError, which is not helpful

I will only backport the segfault fix.  I'll let Anthony decide if he wants
the other changes backported.  I will do the backport if asked.

Walter Dörwald c1f5fff2b7 Apply SF patch #1101726: Fix buffer overrun in tokenizer.c when a source file 
with a PEP 263 encoding declaration results in long decoded line.
 2005-07-12 21:53:43 +00:00
Martin v. Löwis 4bf108d74f Patch #802188: better parser error message for non-EOL following line cont. 2005-03-03 11:45:45 +00:00
Hye-Shik Chang 7df44b384a SF #941229: Decode source code with sys.stdin.encoding in interactive 
modes like non-interactive modes.  This allows for non-latin-1 users
to write unicode strings directly and sets Japanese users free from
weird manual escaping <wink> in shift_jis environments.
(Reviewed by Martin v. Loewis)

Anthony Baxter c2a5a63654 PEP-0318, @decorator-style. In Guido's words: 
"@ seems the syntax that everybody can hate equally"
Implementation by Mark Russell, from SF #979728.
 2004-08-02 06:10:11 +00:00
Jack Jansen eddc1449ba Getting rid of all the code inside #ifdef macintosh too. 2003-11-20 01:44:59 +00:00
Marc-André Lemburg 1fb1400d08 Add URL for PEP to the source code encoding warning. 
Remove the usage of PyErr_WarnExplicit() since this could cause
sensitive information from the source files to appear in e.g.
log files.
 2003-02-17 18:31:57 +00:00
Just van Rossum f032f86e9e patch 680474 that fixes bug 679880: compile/eval/exec refused utf-8 bom 
mark. Added unit test.
 2003-02-09 20:38:48 +00:00
Mark Hammond a2e303c32d Fix [ 665014 ] files with long lines and an encoding crash. 
Ensure that the 'size' arg is correctly passed to the encoding reader to
prevent buffer overflows.
 2003-01-14 23:15:22 +00:00
Martin v. Löwis 95292d6caa Constify filenames and scripts. Fixes #651362. 2002-12-11 14:04:59 +00:00

Tim Peters 17db21ffd0 Removed reliance on gcc/C99 extension. 2002-09-03 15:39:58 +00:00
Martin v. Löwis f62a89b1e0 Ignore encoding declarations inside strings. Fixes #603509. 2002-09-03 11:52:44 +00:00
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.)
 2002-08-16 17:01:09 +00:00
Skip Montanaro 118ec70ea2 provide less mysterious error messages when seeing end-of-line in 
single-quoted strings or end-of-file in triple-quoted strings.
closes patch 586561.
 2002-08-15 01:20:16 +00:00

Jack Jansen cf0a2cfdb2 Added a cast to shut up a compiler warning. 2002-08-05 14:14:05 +00:00
Martin v. Löwis 725bb233b9 Add 1 to lineno in deprecation warning. Fixes #590888. 2002-08-05 01:49:16 +00:00
Martin v. Löwis 1ee99d31d9 Make pgen compile with pydebug. Duplicate normalized names, as it may 
be longer than the old string.
 2002-08-04 20:10:29 +00:00
Martin v. Löwis cd280fb59c Group statements properly. 2002-08-04 18:28:44 +00:00
Tim Peters 2c3f9c6f04 Repaired a fatal compiler error in the debug build: it's not clear what 
this was trying to assert, but the name it referenced didn't exist.
 2002-08-04 17:58:34 +00:00
Tim Peters 919603b27a Squash compiler wng about signed-vs-unsigned mismatch. 2002-08-04 17:56:42 +00:00
Martin v. Löwis 00f1e3f5a5 Patch #534304: Implement phase 1 of PEP 263. 2002-08-04 17:29:52 +00:00
Jack Jansen 7b8c7546eb Mass checkin of universal newline support. 
Highlights: import and friends will understand any of \r, \n and \r\n
as end of line. Python file input will do the same if you use mode 'U'.
Everything can be disabled by configuring with --without-universal-newlines.

See PEP278 for details.
 2002-04-14 20:12:41 +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).
 2001-08-30 20:51:59 +00:00
Tim Peters 9aa70d93aa SF bug [#455775] float parsing discrepancy. 
PyTokenizer_Get:  error if exponent contains no digits (3e, 2.0e+, ...).
 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.
 2001-08-08 05:00:18 +00:00
Tim Peters cf96de052f SF but #417587: compiler warnings compiling 2.1. 
Repaired *some* of the SGI compiler warnings Sjoerd Mullender reported.
 2001-04-21 02:46:11 +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
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
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
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.

Guido van Rossum 6da3434e03 Trent Mick: familiar simple Win64 patches 2000-06-28 22:00:02 +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.)
 2000-05-03 23:44:39 +00:00
Guido van Rossum 6c981ad25e Only write message about changed Tab size with -v. 2000-04-03 23:02:17 +00:00
Guido van Rossum ab5ca15f94 Fix by Eric Raymond: make the code that looks for various bits of 
tab-setting magic much smarter, more correct, and more easily
extensible.

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

Guido van Rossum 5026cb4dc6 Now that the string-sig has settled on r"obin" strings, restrict the 
<letter><string> notation to 'r' and 'R'.

 1993-05-12 08:24:20 +00:00
Guido van Rossum 9bfef44d97 * Changed all copyright messages to include 1993. 
* Stubs for faster implementation of local variables (not yet finished)
* Added function name to code object.  Print it for code and function

  number has changed accordingly)
* Print address of self for built-in methods
* New internal functions getattro and setattro (getattr/setattr with
  string object arg)
