Fix for the UTF-8 decoder: it will now accept isolated surrogates
(previously it raised an exception which causes round-trips to
fail).
Added new tests for UTF-8 round-trip safety (we rely on UTF-8 for
marshalling Unicode objects, so we better make sure it works for
all Unicode code points, including isolated surrogates).
Bumped the PYC magic in a non-standard way -- please review. This
was needed because the old PYC format used illegal UTF-8 sequences
for isolated high surrogates which now raise an exception.
installations are present, by always unlinking the destination file
before copying to it. Without the unlink(), the copied file remains
owned by its previous UID, causing the subsequent chmod() to fail.
Bugfix candidate, though it may cause changes on platforms where
file ownership behaves differently.
contain the type of the file (regular file, socket, link, &c.).
This means that install_scripts will now print
"changing mode of <file> to 775" instead of "... to 100775".
2.2 bugfix candidate, I suppose, though this isn't actually fixing a bug.
TemproraryFileWrapper wrapper anymore, and should be immune from the
problem that a temp file inherited by a spawned process caused an
attempt to close the temp file in the spawning process to blow
up (the unlink in TemporaryFileWrapper.close() blew up with a
"Permission denied" error because, despite that the temp file got
closed in the spawning process, the spawned process still had it open
by virtue of C-level file descriptor inheritance). In context,
that bug took days to figure out <wink/sigh>.
This is an ancient race when multiple threads call gettempdir() (or
anything relying on it) for the first time.
Fixed x-platform via the Big Hammer of rearranging the code to serialize
the first calls. Subsequent calls are as fast as before.
Note that the Python test suite can't provoke this bug: it requires
setting up multiple threads making the very first calls into tempfile,
but the test suite uses tempfile several times before getting to
test_threadedtempfile.
Bugfix candidate.
