Fred Drake 6da0b9148c Michael Hudson <mwh21@cam.ac.uk>:
As I really do not have anything better to do at the moment, I have written
a patch to Python/marshal.c that prevents Python dumping core when trying
to marshal stack bustingly deep (or recursive) data structure.

It just throws an exception; even slightly clever handling of recursive
data is what pickle is for...

[Fred Drake:]  Moved magic constant 5000 to a #define.

This closes SourceForge patch #100645.

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 2efa369861 Use modern PyArg_ParseTuple style, with function names. 2000-03-31 00:37:41 +00:00
Guido van Rossum c279b53b4f Marc-Andre Lemburg: support marshalling Unicode objects (code 'u'). 2000-03-10 23:03:02 +00:00
Guido van Rossum 5bd893b1ea The previous checkin contained an experiment of Greg Stein's that wasn't
meant for checkin, and which broke marshal.loads().
1998-10-08 01:45:47 +00:00
Guido van Rossum d076c73cc8 Changes to support other object types besides strings
as the code string of code objects, as long as they support
the (readonly) buffer interface.  By Greg Stein.

Guido van Rossum a45cb45965 When unmarshalling, add test for negative lengths on strings, tuples
and lists; if the size is negative, raise an exception.  Also raise an
exception when an undefined type is found -- all this to increase the
chance that garbage input causes an exception instead of a core dump.

Guido van Rossum ba7cc0cfba Remove unnecessary PyErr_Clear(). 1998-05-14 02:31:26 +00:00
Guido van Rossum 730806d3d9 Make new gcc -Wall happy 1998-04-10 22:27:42 +00:00
Guido van Rossum 6fc06e770f Plugged a leak. (The same as the one plugged in compile.c -- forgot
to free lnotab).
1997-07-26 23:30:18 +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 79f25d9a7b Quickly renamed the remaining files -- this directory is done. 1997-04-29 20:08:16 +00:00
Guido van Rossum 45b83915f8 New form of PyFPE_END_PROTECT macro. 1997-03-14 04:32:50 +00:00
Guido van Rossum 0ae748d3c4 Changes for Lee Busby's SIGFPE patch set.
New file pyfpe.c and exception FloatingPointError.

Guido van Rossum 98a9b312e8 Marshal the new stacksize item in code objects. 1997-01-17 21:07:08 +00:00
Guido van Rossum c1547d930f Better way to handle 64-bit ints, keeping gcc -Wall happy.
Tested with AMK's help.
1996-12-10 15:39:04 +00:00
Guido van Rossum b0c168cbe8 Tentative changes to make this work better on 64-bit machines.
A plain int that doesn't fit in 32 bits will be marshalled using a new
type.  32 bits machines can't handle this and will issue a warning.
1996-12-05 23:15:02 +00:00
Guido van Rossum d266eb460e New permission notice, includes CNRI. 1996-10-25 14:44:06 +00:00
Guido van Rossum e449af7da9 Ellipses -> Ellipsis rename (the dictionary really says that it should
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
1996-10-11 16:25:41 +00:00
Guido van Rossum 3f3bb3d3c9 Added *PyMarshal_WriteObjectToString() (moved the relevant code there
from marshal_loads()).

Guido van Rossum 6d023c98b0 Added 1995 to copyright message.
bltinmodule.c: fixed coerce() nightmare in ternary pow().
modsupport.c (initmodule2): pass METH_FREENAME flag to newmethodobject().
pythonrun.c: move flushline() into and around print_error().
1995-01-04 19:12:13 +00:00
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 a44031031c Plug memory leak for code objects 1994-10-05 12:24:16 +00:00
Guido van Rossum 1d5735e846 Merge back to main trunk 1994-08-30 08:27:36 +00:00
Guido van Rossum f1dc566328 * Makefile: added all: and default: targets.
* many files: made some functions static; removed "extern int errno;".
* frozenmain.c: fixed bugs introduced on 24 June...
* flmodule.c: remove 1.5 bw compat hacks, add new functions in 2.2a
  (and some old functions that were omitted).
* timemodule.c: added MSDOS floatsleep version .
* pgenmain.c: changed exit() to goaway() and added defn of goaway().
* intrcheck.c: add hack (to UNIX only) so interrupting 3 times
  will exit from a hanging program.  The second interrupt prints
  a message explaining this to the user.
1993-07-05 10:31:29 +00:00
Guido van Rossum 25831652fd Several changes in one:
(1) dictionaries/mappings now have attributes values() and items() as
well as keys(); at the C level, use the new function mappinggetnext()
to iterate over a dictionary.

(2) "class C(): ..." is now illegal; you must write "class C: ...".

(3) Class objects now know their own name (finally!); and minor
improvements to the way how classes, functions and methods are
represented as strings.

(4) Added an "access" statement and semantics.  (This is still
experimental -- as long as you don't use the keyword 'access' nothing
should be changed.)
1993-05-19 14:50:45 +00:00
Guido van Rossum f56e3db1dd Support for frozen scripts; added -i option. 1993-04-01 20:59:32 +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
