as "a bug" because there's no other way in core Python to ensure that
bytes written are actually on disk. At least ZODB wants this guarantee,
for robustness against crashes.
revision 2.234 of posixmodule.c
SF bug 563750 (Alex Martelli): posix_tmpfile():
The file returned by tmpfile() has mode w+b, so use that in the call
to PyFile_FromFile().
Bugfix candidate.
Patch from Mark Hammond, plus code rearrangement and comments from me.
posix_do_stat(): Windows-specific code could try to free() stack
memory in some cases when a path ending with a forward or backward slash
was passed to os.stat().
type.__module__ behavior.
This adds the module name and a dot in front of the type name in every
type object initializer, except for built-in types (and those that
already had this). Note that it touches lots of Mac modules -- I have
no way to test these but the changes look right. Apologies if they're
not. This also touches the weakref docs, which contains a sample type
object initializer. It also touches the mmap test output, because the
mmap type's repr is included in that output. It touches object.h to
put the correct description in a comment.
Anthony Roach.
Release the global interpreter lock around platform spawn calls.
Bugfix candidate? Hard to say; I favor "yes, bugfix".
These clearly *should* have been releasing the GIL all along, if for no
other reason than compatibility with the similar os.system(). But it's
possible some program out there is (a) multithreaded, (b) calling a spawn
function with P_WAIT, and (c) relying on the spawn call to block all their
threads until the spawned program completes. I think it's very unlikely
anyone is doing that on purpose, but someone may be doing so by accident.
This adds unsetenv to posix, and uses it in the __delitem__ method of
os.environ.
(XXX Should we change the preferred name for putenv to setenv, for
consistency?)
This is a big one, touching lots of files. Some of the platforms
aren't tested yet. Briefly, this changes the return value of the
os/posix functions stat(), fstat(), statvfs(), fstatvfs(), and the
time functions localtime(), gmtime(), and strptime() from tuples into
pseudo-sequences. When accessed as a sequence, they behave exactly as
before. But they also have attributes like st_mtime or tm_year. The
stat return value, moreover, has a few platform-specific attributes
that are not available through the sequence interface (because
everybody expects the sequence to have a fixed length, these couldn't
be added there). If your platform's struct stat doesn't define
st_blksize, st_blocks or st_rdev, they won't be accessible from Python
either.
(Still missing is a documentation update.)
