Only declaring these as interns inside the CLI's main C module
caused build problems on some platforms (notably Cygwin), so
this switches them to a regular underscore prefixed "private" C
API declaration.
This kludge is from 1992. Any C99 compiler is going to be able to handle the
ceval dispatch switch.
Anyway, we have much bigger switches than the ceval dispatch one around. (See,
e.g., Objects/unicodetype_db.h.)
The startup refactoring means command line settings
are now applied after settings are read from the
environment.
This updates the way command line settings are applied
to account for that, ensures more settings are first read
from the environment in _PyInitializeCore, and adds a
simple test case covering the flags that are easy to check.
Fix the pthread+semaphore implementation of
PyThread_acquire_lock_timed() when called with timeout > 0 and
intr_flag=0: recompute the timeout if sem_timedwait() is interrupted
by a signal (EINTR).
See also the PEP 475.
The pthread implementation of PyThread_acquire_lock() now fails with
a fatal error if the timeout is larger than PY_TIMEOUT_MAX, as done
in the Windows implementation.
The check prevents any risk of overflow in PyThread_acquire_lock().
Add also PY_DWORD_MAX constant.
Calendar.itermonthdates() will now consistently raise an exception when a date falls outside of the 0001-01-01 through 9999-12-31 range. To support applications that cannot tolerate such exceptions, the new methods itermonthdays3() and itermonthdays4() are added. The new methods return tuples and are not restricted by the range supported by datetime.date.
Thanks @serhiy-storchaka for suggesting the itermonthdays4() method and for the review.
* Add Tools/scripts/smelly.py: script checking if all symbols
exported by libpython start with "Py" or "_Py".
* Modify "make smelly" to run smelly.py: the command now fails with a
non-zero exit code if libpython leaks a "smelly" symbol.
* Travis CI now runs "make smelly"
Rework the code choosing BLAKE2 code paths from using the optimized
variant on all x86_64 machines to using it when SSSE3 or better
supported instructions sets are available.
Firstly, this solves the problem of using pure SSE2 code path on x86_64
machines. As reported in the bug, this code is slower than the reference
code on all tested x86_64 machines. Furthermore, on Athlon64 that lacks
SSSE3, it is even 2.5 times slower than the reference code! Checking
for SSSE3 therefore ensures that the optimized implementation will only
be used when it has a chance of performing better.
Secondly, this makes it possible to use SSSE3+ optimizations on 32-bit
x86 systems. This allows for even 2 times speed gain on modern 32-bit
x86 systems (tested in a 32-bit chroot).
Fix the following Coverity warning:
>>> CID 1420038: Control flow issues (DEADCODE)
>>> Execution cannot reach this statement: "res = sem_trywait(self->han...".
321 res = sem_trywait(self->handle);
The deadcode was introduced by the commit
c872d39d32.
Improve human friendliness of the Popen API: Add text=False as a
keyword-only argument to subprocess.Popen along with a Popen
attribute .text_mode and set this based on the
encoding/errors/universal_newlines/text arguments.
The universal_newlines parameter and attribute are maintained for
backwards compatibility.
