Previously they were allowed to be added, but all searches and
operations treated them as case-sensitive, creating an inconsistency.
The new implementation will change new tags with different case than
existing ones to the version currently in the database.
This may cause some slowdown in collections with a very large number of
tags since the only way to do this at the moment is to scan through
every one of them. Changing the format tags are stored in in the future
may be useful.
deletes in particular take some time for the server to process, but
don't require much bandwidth, leading to the progress appearing to
have pause when content is actually being processed
this also gives the user an idea of how long the process will take to
complete
- media syncing no longer locks the account, so it can be done
in the background in the future, and multiple clients can safely
sync media at the same time
- all operations are now idempotent, so they can be repeatedly safely
in the event of a connection error
- whether it's a normal incremental sync, an initial sync,
or the media database has been deleted, no files will be uploaded
or downloaded if they already exist on the other side
- file removals are now chunked like additions & updates, preventing
timeouts due to large requests
- if the server can't process a chunk in time, it will return a count
of what it did process, so the client can retry the rest
Notes for AnkiDroid:
- when porting this, recommend you pick a different name for the
.media.db2 file, so users don't accidentally copy the AD version to
the desktop or vice versa
- please make sure filenames are added to the zip in NFC form
If duplicate notes are already in the collection and, based on the first
field of all of them, they should be updated, update all of them instead
of just the first one we come across.
When "allow HTML" was turned off, Anki was replacing newlines with <br>s
in the text of the new notes before it escaped HTML characters, so the
line breaks were becoming <br>.
Even if there are several (duplicate) notes in the collection that
match, only send the message once to avoid making it look like multiple
dupes have been added.
This change keeps drag-and-drop behavior the same except for displaying
an error if an otherwise acceptable move would nest anything underneath
a filtered deck.
