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 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.

Guido van Rossum fa48116993 Trent Mick: use size_t instead of int where appropriate (time_strftime()). 2000-06-28 21:33:59 +00:00
Fred Drake aff601804d M.-A. Lemburg <mal@lemburg.com>:
Fixed a bug due to a /* inside /*...*/. GCC doesn't like
this and bombs.

Guido van Rossum c410e92974 Jack Jansen:
This patch is a workaround for Macintosh, where the GUSI I/O library
(time, stat, etc) use the MacOS epoch of 1-Jan-1904 and the MSL C
library (ctime, localtime, etc) uses the (apparently ANSI standard)
epoch of 1-Jan-1900. Python programs see the MacOS epoch and we
convert values when needed.

Andrew M. Kuchling c24ca4b192 Fix probable bug; if errno == EINTR, floatsleep() doesn't break out of
a Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS block, but it
   calls Py_BLOCK_THREADS anyway. The change moves Py_BLOCK_THREADS
   to inside the if, so it's only executed when the function
   actually returns unexpectedly.

Jeremy Hylton 7ceab65468 Fix bogus error reporting on strptime: let PyArg_ParseTuple set exception.
Also, wrap long line.

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 b2b42ddcb1 The functions asctime() and mktime() are documented to take a 9-tuple
only.  Through some mysterious interaction, they would take 9 separate
arguments as well.  This misfeature is now disabled (to end a
difference with JPython).

Guido van Rossum 09cbb01989 Jack Jansen: Mac has no EINTR. 1999-11-08 15:32:27 +00:00
Guido van Rossum a5456d5042 In floatsleep(), when using select(), ignore EINTR error. 1999-08-19 14:40:27 +00:00
Guido van Rossum ea424e19f1 Apparently __GNU_LIBRARY__ is defined for glibc as well as for libc5.
The test really wanted to distinguish between the two.  So now we test
for __GLIBC__ instead.  I have confirmed that this works for glibc and
I have an email from Christian Tanzer confirming that it works for
libc5, so it should be fine.

Guido van Rossum 0ffdd05cc3 Jonathan Giddy notes, and Chris Lawrence agrees, that some comments on
#else/#endif are wrong, and that #if HAVE_TM_ZONE should be #ifdef.

Guido van Rossum 57731607c3 Chris Lawrence writes:
"""
The GNU folks, in their infinite wisdom, have decided not to implement
altzone in libc6; this would not be horrible, except that timezone
(which is implemented) includes the current DST setting (i.e. timezone
for Central is 18000 in summer and 21600 in winter).  So Python's
timezone and altzone variables aren't set correctly during DST.

Here's a patch relative to 1.5.2b2 that (a) makes timezone and altzone
show the "right" thing on Linux (by using the tm_gmtoff stuff
available in BSD, which is how the GLIBC manual claims things should
be done) and (b) should cope with the southern hemisphere.  In pursuit
of (b), I also took the liberty of renaming the "summer" and "winter"
variables to "july" and "jan".  This patch should also make certain
time calculations on Linux actually work right (like the tz-aware
functions in the rfc822 module).

(It's hard to find DST that's currently being used in the southern
hemisphere; I tested using Africa/Windhoek.)

Guido van Rossum d3eb5774ad Patch by Chris Herborth for BeOS code.
He writes:

I had an off-by-1000 error in floatsleep(),
and the problem with time.clock() is that it's not implemented properly
on QNX... ANSI says it's supposed to return _CPU_ time used by the
process, but on QNX it returns the amount of real time used... so I was
confused.

Guido van Rossum c222ec28a5 Patch by Tadayoshi Funaba (with some changes) to be smarter about
guessing what happened when strftime() returns 0.  Is it buffer
overflow or was the result simply 0 bytes long?  (This happens for an
empty format string, or when the format string is a single %Z and the
timezone is unknown.)  if the buffer is at least 256 times as long as
the format, assume the latter.
1999-02-23 00:00:10 +00:00
Guido van Rossum 360eb9f278 We don't support leap seconds, so the seconds field of a time 9-tuple
should be in the range [0-59].  Noted by Tadayoshi Funaba.
1999-02-22 16:19:52 +00:00
Guido van Rossum 446ccfe1ac The doc string for strptime had the arguments reversed -- the string
comes first, the format second!  Scott Cotton discovered this.
1999-01-07 18:29:26 +00:00
Guido van Rossum 0a6363d7e1 Get rid of the strptype() declaration -- on some BSD systems, it's a
conflict, and it should be declared in time.h anyway.
(Too bad if gcc -Wall won't be happy if it isn't declared...)
1999-01-03 13:00:34 +00:00
Guido van Rossum 3886bb6997 Add DL_EXPORT() to all modules that could possibly be used
on BeOS or Windows.
1998-12-04 18:50:17 +00:00
Guido van Rossum c20687355b Make gcc -Wall happy:
(1) add dummy decl for strptime();
(2) move the code to set accept2dyear to the front of inittime().

Guido van Rossum 2645241add Fixes for OS/2 by Jeff Rush. 1998-09-28 22:07:11 +00:00
Guido van Rossum cfbaecc546 Y2K fix affecting asctime(), mktime(), strftime().
2-digit years are now converted using rules that are (according to
Fredrik Lundh) recommended by POSIX or X/Open: 0-68 mean 2000-2068,
69-99 mean 1969-1999.

2-digit years are now only accepted if time.accept2dyear is set to a
nonzero integer; if it is zero or not an integer or absent, only year
values >= 1900 are accepted.  Year values 100-1899 and negative year
values are never accepted.

The initial value of time.accept2dyear depends on the environment
variable PYTHONY2K: if PYTHONY2K is set and non-empty,
time.accept2dyear is initialized to 0; if PYTHONY2K is empty or not
set, time.accept2dyear is initialized to 0.

Guido van Rossum 0ef577b966 Added doc strings. 1998-06-27 20:38:36 +00:00
Guido van Rossum 87ce7bbc39 Added strptime, if it exists. Modified after a patch by Jesse Hallio. 1998-06-09 16:30:31 +00:00
Guido van Rossum 1f41f846a3 Instead of calling mktime(), which has all sorts of unwanted side
effects, simply zero out the struct tm buffer before using it; this
should take care of the BSD folks' concern just as well.
1998-04-27 19:04:26 +00:00
Guido van Rossum 60cd813810 Check for HAVE_MKTIME (if you don't have it, some tests will fail, but
at least the build will now succeed).  For Sony NEWS-OS, BSD 4.3 based.

Guido van Rossum 7853570651 Raise ValueError: "unconvertible time" when ctime() returns NULL,
instead of dumping core.
1998-03-03 22:19:10 +00:00
Guido van Rossum 1d0d7e4e48 At Jeff Rush' request, add Py_BEGIN/END_ALLOW_THREADS around call to
DosSleep().
1997-12-29 20:03:10 +00:00
Guido van Rossum be1eb0d9ed (1) call mktime() just before strftime(); it normalizes the buffer and
may set the timezone name for BSD systems...

(2) fake all of the timezone variables for the mac.

Guido van Rossum 8e9ebfd337 os2 patch by Jeff Rush 1997-11-22 21:53:48 +00:00
Guido van Rossum 8607ae2e57 Move the Py_{{BEGIN,END}_ALLOW,BLOCK}_THREADS macros in time_sleep()
to inside floatsleep().  This is necessary because floatsleep() does
the error handling and it must have grabbed the interpreter lock and
thread state before it can do so.

a conflicting definition somewhere).
Resolved line wrap for error message in ins().

Guido van Rossum b2fb36498d Sleep() turns out to be win32 specific.
The timezone etc. overrides are win16 specific.
Hope I got this right now...
