timeout when interrupted by a signal, except if the signal handler raises an
exception. This change is part of the PEP 475.
The asyncore and selectors module doesn't catch the InterruptedError exception
anymore when calling select.select(), since this function should not raise
InterruptedError anymore.
The previous patch only dealt with KeyboardInterrupt when all of the
data had been consumed by the pager. This deals with the interrupt
when some data is still pending.
This mimics get_param's error handling for the most part. It is slightly
better in some regards as get_param can produce some really weird results for
duplicate *0* parts. It departs from get_param slightly in that if we have a
mix of non-extended and extended pieces for the same parameter name, the new
parser assumes they were all supposed to be extended and concatenates all the
values, whereas get_param always picks the non-extended parameter value. All
of this error recovery is pretty much arbitrary decisions...
Previously, if you hit ctl-c while the pager was active, the python that
launched the subprocess for the pager would see the KeyboardInterrupt in the
__exit__ method of the subprocess context manager where it was waiting for the
subprocess to complete, ending the wait. This would leave the pager running,
while the interactive interpreter, after handling the exception by printing
it, would go back to trying to post a prompt...but the pager would generally
have the terminal in raw mode, and in any case would be still trying to read
from stdin. On some systems, even exiting python at that point would not
restore the terminal mode. The problem with raw mode could also happen if
ctl-C was hit when pydoc was called from the shell command line and the pager
was active.
Instead, we now wait on the subprocess in a loop, ignoring KeyboardInterrupt
just like the pager does, until the pager actually exits.
(Note: this was a regression relative to python2...in python2 the pager
is called via system, and system does not return until the pager exits.)
* _PyTime_AsTimeval() now ensures that tv_usec is always positive
* _PyTime_AsTimespec() now ensures that tv_nsec is always positive
* _PyTime_AsTimeval() now returns an integer on overflow instead of raising an
exception
* Rename _PyTime_FromObject() to _PyTime_FromSecondsObject()
* Add _PyTime_AsNanosecondsObject() and _testcapi.pytime_fromsecondsobject()
* Add unit tests
Use time.gmtime() instead of time.sleep(), because time.sleep() is no more
declared with METH_VARARGS but with METH_O. time.gmtime() is still declared
with METH_VARARGS and so it is called with PyCFunction_Call() which is the
target of the test_gdb unit test.
