media.py sets CWD to the media directory of the collection
(collection.media), and relies on that directory being
maintained as CWD throughout execution. The original CWD
is restored in the close() function.
Remove reliance on CWD being set and maintained throughout
execution of media.py. Improves portability and usability
in different codebases.
Before sqlite 3.15, the parameter to vacuum was ignored. Since sqlite
3.15, it became a database name parameter. The "vacuum analyze" syntax
was never supported by sqlite, seems to be just a psql thing.
The error for this is "OperationalError: unknown database analyze", and
happens when doing a media sync.
we need to switch to autocommit mode before executing vacuums &
certain pragmas
also removed the pysqlite version workaround; we just use the
python-provided versions in all cases now as it is new enough
- wrap request in AnkiRequestsClient so we can keep track of
upload/download bytes without having to monkey patch anything
- force a 64kB buffer size instead of the default 8kB
- show one decimal point in up/down so small requests still give
visual feedback
- update add-on downloading and update check to use requests
- remove the update throttling in aqt/sync.py, as it's not really
necessary anymore
- fix an extra \r\n being included at the end of the last form var
- req()s in the middle of a sync should throw an exception if they
receive a 403, as the calling code does not check for an empty return
universal_newlines uses system locale which is ascii on osx unless
LC_CTYPE/LANG is set to utf8, so we need to be explicit about the
encoding we want instead
we also lose line buffering, so we have to explicitly flush
