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 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 43713e5a28 Massive patch by Skip Montanaro to add ":name" to as many
PyArg_ParseTuple() format string arguments as possible.

Guido van Rossum 947a0fa4f9 According to Ron Bickers, and with apparent approval of Chris
Herborth, the code in list2set() that sets max unconditionally to 0
should not be used on BeOS.  So be it.  Anybody using BeOS, please
test!

Guido van Rossum bcc207484a Changes for BeOS, QNX and long long, by Chris Herborth. 1998-08-04 22:53:56 +00:00
Guido van Rossum d20781b518 On Windows, put the select file descriptor arrays on the heap.
This is because they are huge and the stack is limited on Windows.
Other platforms keep declaring it on the stack.

Guido van Rossum 8e9ebfd337 os2 patch by Jeff Rush 1997-11-22 21:53:48 +00:00
Guido van Rossum 0cb96de269 Apply two changes, systematically:
(1) Use PyErr_NewException("module.class", NULL, NULL) to create the
    exception object.

(2) Remove all calls to Py_FatalError(); instead, return or
    ignore the errors -- the import code now checks PyErr_Occurred()
    after calling a module's init function, so it's no longer a
    fatal error for the initialization to fail.

Also did some small cleanups, e.g. removed unnecessary test for
"already initialized" from initfpectl(), and unified
initposix()/initnt().

I haven't checked this very thoroughly, so while the changes are
pretty trivial -- beware of untested code!

Barry Warsaw 529fcfe31f list2set(): correct return value (an int, not a PyObject*). 1996-12-16 18:15:34 +00:00
Barry Warsaw 24c4b3d4e8 list2set(): PyList_GetItem could fail. 1996-12-13 23:22:42 +00:00
Barry Warsaw c1cb360683 Reworked to eliminate all potential memory problems, including
deletion of object from list argument during callout to fileno().

Barry Warsaw e4ac0aa618 Several changes... Guido *please* take a look!
1. Renamed

2. Several coding styles were being used here, owing to the multiple
   contributors.  I tried to convert everything to standard "python"
   coding style for indentation, paren and brace placement, etc.

3. There were several potential error conditions that were never being
   checked, and where I saw them, I added checks of return values,
   etc.  I'm pretty sure I got them all.

4. There were some old-style (pre PyArg_ParseTuple) argument
   extraction and these were converted to use PyArg_ParseTuple.

All changes compile and run with the new test_select.py module, at
least on my Solaris/Sparc box.

Sjoerd Mullender 78ed420314 Fixed a couple of bugs: getargs doesn't use % escapes, and seconds
must be set after timeout is initialized.
