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.

Barry Warsaw b78165566e Exception__str__(): In case 1, be sure to decref the tmp local
variable.  This crushes another memory leak.  Slight rewrite
included.

Barry Warsaw 7dfeb42939 EnvironmentError__init__(): The two case clauses were missing
`break's.  This first missing break caused a memory leak when case 3
fell through case 2 in the following example:

os.chmod('/missing', 0600)

Tim Peters 4be47c0f76 Get rid of unused vars in builtin_unicode (they were causing
legit warnings).

Marc-André Lemburg 1b1bcc9935 Fixed unicode() to use the new API PyUnicode_FromEncodedObject().
This adds support for instance to the constructor (instances
have to define __str__ and can return Unicode objects via that
hook; string return values are decoded into Unicode using the
current default encoding).

Fred Drake 615ae55eca Trent Mick <trentm@activestate.com>:
The common technique for printing out a pointer has been to cast to a long
and use the "%lx" printf modifier. This is incorrect on Win64 where casting
to a long truncates the pointer. The "%p" formatter should be used instead.

The problem as stated by Tim:
> Unfortunately, the C committee refused to define what %p conversion "looks
> like" -- they explicitly allowed it to be implementation-defined. Older
> versions of Microsoft C even stuck a colon in the middle of the address (in
> the days of segment+offset addressing)!

The result is that the hex value of a pointer will maybe/maybe not have a 0x
prepended to it.


Notes on the patch:

There are two main classes of changes:
- in the various repr() functions that print out pointers
- debugging printf's in the various thread_*.h files (these are why the
patch is large)


Closes SourceForge patch #100505.

Fred Drake 4c82b2366f Trent Mick <trentm@activestate.com>:
This patch fixes possible overflow in the use of
PyOS_GetLastModificationTime in getmtime.c and Python/import.c.

Currently PyOS_GetLastModificationTime returns a C long. This can
overflow on Win64 where sizeof(time_t) > sizeof(long). Besides it
should logically return a time_t anyway (this patch changes this).

As well, import.c uses PyOS_GetLastModificationTime for .pyc
timestamping.  There has been recent discussion about the .pyc header
format on python-dev.  This patch adds oveflow checking to import.c so
that an exception will be raised if the modification time
overflows. There are a few other minor 64-bit readiness changes made
to the module as well:

- size_t instead of int or long for function-local buffer and string
length variables

- one buffer overflow check was added (raises an exception on possible
overflow, this overflow chance exists on 32-bit platforms as well), no
other possible buffer overflows existed (from my analysis anyway)

Closes SourceForge patch #100509.

Guido van Rossum 5e08cb8e50 Vladimir Marangozov:
This patch fixes a problem on AIX with the signed int case code in
getargs.c, after Trent Mick's intervention about MIN/MAX overflow
checks. The AIX compiler/optimizer generates bogus code with the
default flags "-g -O" causing test_builtin to fail: int("10", 16) <>
16L. Swapping the two checks in the signed int code makes the problem
go away.

Also, make the error messages fit in 80 char lines in the
source.

Guido van Rossum 98626cd7ac Urmpf. Quality control on this patch lapsed a bit. :-(
The depth field was never decremented inside w_object(), and it was
never initialized in PyMarshal_WriteObjectToFile().

This caused imports from .pyc files to fil mysteriously when the .pyc
file was written by the broken code -- w_object() would bail out
early, but PyMarshal_WriteObjectToFile() doesn't check the error or
return an error code, and apparently the marshalling code doesn't call
PyErr_Check() either.  (That's a separate patch if I feel like it.)

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

Guido van Rossum 106f2dae86 Trent Mick:
Various small fixes to the builtin module to ensure no buffer
overflows.

- chunk #1:
Proper casting to ensure no truncation, and hence no surprises, in the
comparison.

- chunk #2:
The id() function guarantees a unique return value for different
objects.  It does this by returning the pointer to the object. By
returning a PyInt, on Win64 (sizeof(long) < sizeof(void*)) the pointer
is truncated and the guarantee may be proven false. The appropriate
return function is PyLong_FromVoidPtr, this returns a PyLong if that
is necessary to return the pointer without truncation.

[GvR: note that this means that id() can now return a long on Win32
platforms.  This *might* break some code...]

- chunk #3:
Ensure no overflow in raw_input(). Granted the user would have to pass
in >2GB of data but it *is* a possible buffer overflow condition.

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.

Jeremy Hylton 94988067b9 Add new parser error code, E_OVERFLOW. This error is returned when
the number of children of a node exceeds the max possible value for
the short that is used to count them.  The Python runtime converts
this parser error into the SyntaxError "expression too long."

Mark Hammond 440d898230 Added a new debug method sys.gettotalrefcount(), which returns the total number of references on all Python objects. This is only enabled when Py_TRACE_REFS is defined (which includes default debug builds under Windows).
Also removed a redundant cast from sys.getrefcount(), as discussed on the patches list.

Barry Warsaw 675ac285ae The standard exception classes. Moved here from ../Modules/_exceptions.c 2000-05-26 19:05:16 +00:00
Barry Warsaw f17861badc Added exceptions.o to the list of object to build in this subdir. 2000-05-26 19:04:27 +00:00
Barry Warsaw 78e6c671db All the exception building related stuff has been moved out of this
module and into _exceptions.c.  This includes all the PyExc_* globals,
the bltin_exc table, init_class_exc(), fini_instances(),
finierrors().

Renamed _PyBuiltin_Init_1() to _PyBuiltin_Init() since the two phase
initializations are necessary any more.

Removed as obsolete _PyBuiltin_Init_2(), _PyBuiltin_Fini_1() and
_PyBuiltin_Fini_2().
2000-05-25 23:15:05 +00:00
Barry Warsaw f242aa0d1e Py_Initialize(): Now that standard exceptions are builtin, we don't
need two phase init or fini of the builtin module.  Change the call of
_PyBuiltin_Init_1() to _PyBuiltin_Init().  Add a call to
init_exceptions().

Py_Finalize(): Don't call _PyBuiltin_Fini_1().  Instead call
fini_exceptions() but move this to before the thread state is
cleared.
2000-05-25 23:09:49 +00:00
Barry Warsaw 1226588e57 bltin_exc: Removed the leaf_exc flag in the structure, which was only

Guido van Rossum 80dc16baaa Trent Mick:
Changes the 'b', 'h', and 'i' formatters in PyArg_ParseTuple to raise an
Overflow exception if they overflow (previously they just silently
overflowed).

Changes by Guido: always accept values [0..255] (in addition to
[CHAR_MIN..CHAR_MAX]) for 'b' format; changed some spaces into tabs in
other code.
