behavior, creating many threads very quickly. A long debugging session
revealed that the Windows implementation of PyThread_start_new_thread()
was choked with "laziness" errors:
1. It checked MS _beginthread() for a failure return, but when that
happened it returned heap trash as the function result, instead of
an id of -1 (the proper error-return value).
2. It didn't consider that the Win32 CreateSemaphore() can fail.
3. When creating a great many threads very quickly, it's quite possible
that any particular bootstrap call can take virtually any amount of
time to return. But the code waited for a maximum of 5 seconds, and
didn't check to see whether the semaphore it was waiting for got
signaled. If it in fact timed out, the function could again return
heap trash as the function result. This is actually what confused
the test program, as the heap trash usually turned out to be 0, and
then multiple threads all got id 0 simultaneously, confusing the
hell out of threading.py's _active dict (mapping id to thread
object). A variety of baffling behaviors followed from that.
WRT #1 and #2, error returns are checked now, and "thread.error: can't
start new thread" gets raised now if a new thread (or new semaphore)
can't be created. WRT #3, we now wait for the semaphore without a
timeout.
Also removed useless local vrbls, folded long lines, and changed callobj
to a stack auto (it was going thru malloc/free instead, for no discernible
reason).
Bugfix candidate.
time.tzname[1] and not time.daylight`` is true when it should only when
time.daylight is true. Tests are also fixed.
Closes bug #763047 and its cohort #763052.
(which is not to say it's right), so re-enable it.
Documenting Python and Installing Python Modules still have problems
when converting to GNU info, so we'll continue to leave them out for
now.
because it was still looking in the ossaudiodev module namespace for
this symbol.
As the symbol has already been rebound as a global, use that instead.
scope of the _XOPEN_SOURCE and _POSIX_C_SOURCE symbols, including:
- getloadavg()
- typedefs for u_int, u_long, u_char, u_short, ushort & uint
These are now all defined under the control of a __BSD_VISIBLE symbol.
The lack of the typedefs causes several extension modules to build
incorrectly or not at all, and is the cause of failures reported for
test_socket and test_tempfile on this platform
(see python-dev: 29/6/03, pieterb@gewis.nl, "Running tests on freebsd5")
This change does not appear to be needed in the 2.2 branch.
