Guido van Rossum ce8e1dc395 clean up warnings in Win32 build of mmapmodule.c 2000-07-01 00:51:51 +00:00
Guido van Rossum 9f754e0e2d In b_setitem(), instead of the platform dependent CHAR_MIN and
CHAR_MAX, use hardcoded -128 and 127.  This may seem strange, unless
you realize that we're talking about signed bytes here!  Bytes are
always 8 bits and 2's complement.  CHAR_MIN and CHAR_MAX are
properties of the char data type, which is guaranteed to hold at least
8 bits anyway.

Otherwise you'd get failing tests on platforms where unsigned char is
the default (e.g. AIX).

Thanks, Vladimir Marangozov, for finding this nit!

Fred Drake a44d353e2b 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.

Fredrik Lundh 0640e1161f the mad patcher strikes again:
-- added pickling support (only works if sre is imported)

-- fixed wordsize problems in engine
   (instead of casting literals down to the character size,
   cast characters up to the literal size (same as the code
   word size).  this prevents false hits when you're matching
   a unicode pattern against an 8-bit string. (unfortunately,
   this broke another test, but I think the test should be
   changed in this case; more on that on python-dev)

-- added sre.purge function
   (unofficial, clears the cache)

Fred Drake a04eaad5c7 Trent Mick <trentm@activestate.com>:
This patch fixes possible overflows in the socket module for 64-bit
platforms (mainly Win64). The changes are:

- abstract the socket type to SOCKET_T (this is SOCKET on Windows, int
on Un*x), this is necessary because sizeof(SOCKET) > sizeof(int) on
Win64

- use INVALID_SOCKET on Win32/64 for an error return value for
accept()

- ensure no overflow of the socket variable for: (1) a PyObject return
value (use PyLong_FromLongLong if necessary); and (2) printf
formatting in repr().

Closes SourceForge patch #100516.

Guido van Rossum f385c5e544 Patch by Nadav Horesh to make acosh and asinh better.
Tim posted a long comment to python-dev (subject: "Controversial patch
(cmath)"; date: 6/29/00).  The conclusion is that this whole module
stinks and this patch isn't perfect, but it's better than the acosh
and asinh we had, so let's check it in.

Fredrik Lundh 01016fe972 - fixed split behaviour on empty matches

2000-06-30 00:27:46 +00:00
Fredrik Lundh 29c08beab0 still trying to figure out how to fix the remaining
group reset problem.  in the meantime, I added some
optimizations:

- added "inline" directive to LOCAL

  (this assumes that AC_C_INLINE does what it's
  supposed to do).  to compile SRE on a non-unix
  platform that doesn't support inline, you have
  to add a "#define inline" somewhere...

- added code to generate a SRE_OP_INFO primitive

- added code to do fast prefix search

  (enabled by the USE_FAST_SEARCH define; default
  is on, in this release)

Fred Drake 0e12395190 Trent Mick <trentm@activestate.com>:
This patch fixes a possible overflow in the Sleep system call on
Win32/64 in the time_sleep() function in the time module. For very
large values of the give time to sleep the number of milliseconds can
overflow and give unexpected sleep intervals. THis patch raises an
OverflowError if the value overflows.

Closes SourceForge patch #100514.

Fred Drake 699f352fb2 Trent Mick <trentm@activestate.com>:
This patch fixes the posix module for large file support mainly on
Win64, although some general cleanup is done as well.

The changes are:

- abstract stat->STAT, fstat->FSTAT, and struct stat->STRUCT_STAT
This is because stat() etc. are not the correct functions to use on
Win64 (nor maybe on other platforms?, if not then it is now trivial to
select the appropriate one). On Win64 the appropriate system functions
are _stati64(), etc.

- add _pystat_fromstructstat(), it builds the return tuple for the
fstat system call. This functionality was being duplicated. As well
the construction of the tuple was modified to ensure no overflow of
the time_t elements (sizeof(time_t) > sizeof(long) on Win64).

- add overflow protection for the return values of posix_spawnv and
posix_spawnve

- use the proper 64-bit capable lseek() on Win64

- use intptr_t instead of long where appropriate from Win32/64 blocks
(sizeof(void*) > sizeof(long) on Win64)

This closes SourceForge patch #100513.

Fred Drake dfb4ebda24 Trent Mick <trentm@activestate.com>:
Mark Hammond provided (a long time ago) a better Win32 specific
time_clock implementation in timemodule.c. The library for this
implementation does not exist on Win64 (yet, at least). This patch
makes Win64 fall back on the system's clock() function for
time_clock().

This closes SourceForge patch #100512.

Fredrik Lundh 8094611eb8 - fixed another split problem
(those semantics are weird...)

- got rid of $Id$'s (for the moment, at least).  in other
  words, there should be no more "empty" checkins.

- internal: some minor cleanups.
2000-06-29 18:03:25 +00:00
Fredrik Lundh be2211e940 - fixed split
(test_sre still complains about split, but that's caused by
  the group reset bug, not split itself)

- added more mark slots
  (should be dynamically allocated, but 100 is better than 32.
  and checking for the upper limit is better than overwriting
  the memory ;-)

- internal: renamed the cursor helper class

- internal: removed some bloat from sre_compile

Fredrik Lundh 75f2d675ed - last patch broke parse_template; fixed by changing some

Guido van Rossum cc6a438d7f Trent Mick:
Fix warnings on 64-bit build build of signalmodule.c

- Though I know that SIG_DFL and SIG_IGN are just small constants,
there are cast to function pointers so the appropriate Python call is
PyLong_FromVoidPtr so that the pointer value cannot overflow on Win64
where sizeof(long) < sizeof(void*).

Guido van Rossum 534b7c5c96 Trent Mick:
This patch fixes cPickle.c for 64-bit platforms.

- The false assumption sizeof(long) == size(void*) exists where
PyInt_FromLong is used to represent a pointer. The safe Python call
for this is PyLong_FromVoidPtr. (On platforms where the above
assumption *is* true a PyInt is returned as before so there is no
effective change.)

- use size_t instead of int for some variables

Guido van Rossum 3262e16753 Trent Mick:
This patches fixes a possible overflow of the optional timeout
parameter for the select() function (selectmodule.c). This timeout is
passed in as a double and then truncated to an int. If the double is
sufficiently large you can get unexpected results as it
overflows. This patch raises an overflow if the given select timeout
overflows.

[GvR: To my embarrassment, the original code was assuming an int could
always hold a million.  Note that the overflow check doesn't test for
a very large *negative* timeout passed in -- but who in the world
would do such a thing?]

Guido van Rossum 40ced50cb0 Jack Jansen: Mac Carbon: don't include sys/types if we don't have it 2000-06-28 20:56:30 +00:00
Fred Drake 541dc3b7b2 Trent Mick <trentm@activestate.com>:
The cause: Relatively recent (last month) patches to getargs.c added
overflow checking to the PyArg_Parse*() integral formatters thereby
restricting 'b' to unsigned char value and 'h','i', and 'l' to signed
integral values (i.e. if the incoming value is outside of the
specified bounds you get an OverflowError, previous it silently
overflowed).

The problem: This broke the array module (as Fredrik pointed out)
because *its* formatters relied on the loose allowance of signed and
unsigned ranges being able to pass through PyArg_Parse*()'s
formatters.

The fix: This patch fixes the array module to work with the more
strict bounds checking now in PyArg_Parse*().

How: If the type signature of a formatter in the arraymodule exactly
matches one in PyArg_Parse*(), then use that directly. If there is no
equivalent type signature in PyArg_Parse*() (e.g. there is no unsigned
int formatter in PyArg_Parse*()), then use the next one up and do some
extra bounds checking in the array module.

This partially closes SourceForge patch #100506.
