any errors that might occur during coercion of the left operand and
turning them into a TypeError with a message text that was confusing in
the given context. This patch lets any errors through, as was already
done during coercion of the right hand side.
This is for consistency with imitation file objects like StringIO and BytesIO.
This commit also adds a few tests, where they were lacking for concerned
methods.
missing proper end-of-line termination. Patch and tests by
Scott Dial. The new tests include a test harness which will
make it easier to add additional tests.
`storbinary()` method of FTP and FTP_TLS objects gains an optional `rest`
argument. Patch by Pablo Mouzo.
(note: the patch also adds a test for the rest argument in retrbinary())
The reference to copyreg was a unnoticed leftover from the compatibility
support for the grand renaming of the standard library in Python 3. The
compatibility support was reverted in r63493, but not completely as this
patch shows.
Based on a patch by Amaury Forgeot d'Arc.
(Note that an empty archive is not the same as an empty file. An
empty archive contains no members and is correctly terminated with an
EOF block full of zeros. An empty file contains no data at all.)
The problem was that although tarfile was able to create empty
archives, it failed to open them raising a ReadError. On the other
hand, tarfile opened empty files without error in most read modes and
presented them as empty archives. (However, some modes still raised
errors: "r|gz" raised ReadError, but "r:gz" worked, "r:bz2" even
raised EOFError.)
In order to get a more fine-grained control over the various internal
error conditions I now split up the HeaderError exception into a
number of meaningful sub-exceptions. This makes it easier in the
TarFile.next() method to react to the different conditions in the
correct way.
The visible change in its behaviour now is that tarfile will open
empty archives correctly and raise ReadError consistently for empty
files.
properly, and use this to skip test_multiprocessing on platforms
where sem_open raises a signal. This should fix some FreeBSD buildbot
failures for test_multiprocessing.
- Fix#7362: give a good error message for parenthesized arguments with
defaults.
- Add a py3k warning for any parenthesized arguments since those are not allowed
in Py3. This warning is not given in tuple unpacking, since that incurs the
tuple unpacking warning.
string <-> float conversions; this makes sure that the result of the round
operation is correctly rounded, and hence displays nicely using the new float
repr.
