Thomas Wouters c6e55068ca Use Py_VISIT in all tp_traverse methods, instead of traversing manually or
using a custom, nearly-identical macro. This probably changes how some of
these functions are compiled, which may result in fractionally slower (or
faster) execution. Considering the nature of traversal, visiting much of the
address space in unpredictable patterns, I'd argue the code readability and
maintainability is well worth it ;P

Thomas Wouters edf17d8798 Use Py_CLEAR instead of in-place DECREF/XDECREF or custom macros, for
tp_clear methods.

Neal Norwitz 2aa9a5dfdd Use macro versions instead of function versions when we already know the type.
This will hopefully get rid of some Coverity warnings, be a hint to
developers, and be marginally faster.

Some asserts were added when the type is currently known, but depends
on values from another function.

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.

Nicholas Bastin a7604bf1b4 Moved tracebackobject to traceback.h, Closes SF Bug #497067 2004-03-21 18:37:23 +00:00
Jack Jansen fb2765666f Getting rid of support for the ancient Apple MPW compiler. 2003-11-19 15:24:47 +00:00
Michael W. Hudson c85b6a2d4d After the removal of SET_LINENO, PyCode_Addr2Line has always been
called to find tb_lineno -- even if Py_OptimizeFlag is true.

So don't call it again when printing the traceback.

Michael W. Hudson dd32a91cc0 This is my patch
[ 587993 ] SET_LINENO killer

Remove SET_LINENO.  Tracing is now supported by inspecting co_lnotab.

Many sundry changes to document and adapt to this change.

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.

Jeremy Hylton 518ab1c02a Use PyOS_snprintf instead of sprintf. 2001-11-28 20:42:20 +00:00
Tim Peters 6d20b43a4e SF bug 485175: buffer overflow in traceback.c.
Bugfix candidate.
tb_displayline():  the sprintf format was choking off the file name, but
used plain %s for the function name (which can be arbitrarily long).
Limit both to 500 chars max.

Jeremy Hylton fd14d8e187 Make traceback objects collectable.
This should eliminate the traceback returned by sys.exc_info() as a
common source of memory leaks.

Tim Peters d7c3652aa7 Removed two pointless and obfuscating macros. 2001-10-22 19:34:09 +00:00
Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.
This should match the situation in the 1.6b1 tree.

Thomas Wouters f70ef4f860 Mass ANSIfication of function definitions. Doesn't cover all 'extern'
declarations yet, those come later.

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

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 6d10887cdc Change traceback error message to "most recent call last" from
"innermost last".  The latter was mysterious to newbies.

Guido van Rossum d724b23420 Christian Tismer's "trashcan" patch:
Added wrapping macros to dictobject.c, listobject.c, tupleobject.c,
frameobject.c, traceback.c that safely prevends core dumps
on stack overflow. Macros and functions in object.c, object.h.
The method is an "elevator destructor" that turns cascading
deletes into tail recursive behavior when some limit is hit.

Guido van Rossum 3aca65312a Tim Peters fixed PR#75: very long lines cause incorrect tracebacks. 1999-09-18 20:49:39 +00:00
Guido van Rossum 7e8d26d78c PyFile_WriteString now returns an error indicator instead of calling
PyErr_Clear().  Add checking of those errors.
1997-05-22 22:35:47 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management.
All per-thread globals are moved into a struct which is manipulated
separately.

Guido van Rossum b3f515af64 Get the line number from PyCode_Addr2Line instead of believing
tb_lineno.  Store it in tb_lineno for the user.

Guido van Rossum 1ae940a587 Lots of changes, most minor (fatal() instead of abort(), use of
err_fetch/err_restore and so on).  But...
NOTE: import.c has been rewritten and all the DL stuff is now in the
new file importdl.c.

Guido van Rossum bfd5d755a0 * Python/traceback.c: security fix -- check for buffer oveflow
before concatenating sys.path item and module name

Guido van Rossum 13836d9e6d add function name to traceback info
MPW fixes
1994-08-29 12:09:58 +00:00
Guido van Rossum 67a5fdbcc2 * mpzmodule.c: cast some methods to the proper type.
* traceback.c (tb_print): use sys.tracebacklimit as a maximum number of
  traceback entries to print (default 1000).
* ceval.c (printtraceback): Don't print stack trace header -- this is now
  done by tb_print().
1993-12-17 12:09:14 +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
  objects.  THIS MAKES THE .PYC FILE FORMAT INCOMPATIBLE (the version
  number has changed accordingly)
* Print address of self for built-in methods
* New internal functions getattro and setattro (getattr/setattr with
  string object arg)
* Replaced "dictobject" with more powerful "mappingobject"
* New per-type functio tp_hash to implement arbitrary object hashing,
  and hashobject() to interface to it
* Added built-in functions hash(v) and hasattr(v, 'name')
* classobject: made some functions static that accidentally weren't;
  added __hash__ special instance method to implement hash()
* Added proper comparison for built-in methods and functions
1993-03-29 10:43:31 +00:00
Guido van Rossum 3165fe6a56 Modified most (but not yet all) I/O to always go through sys.stdout or
sys.stderr or sys.stdin, and to work with any object as long as it has
a write() (respectively readline()) methods.  Some functions that took
a FILE* argument now take an object* argument.

Guido van Rossum 247ff718df Don't use printobject() to print a string (filename).
Print ';' instead of ',' between file and line for MPW.
