It seems like there's an issue with Android that sometimes the userData
passed to addAccountExplicitly is not correctly set in the Android cache
making it return null on subsequent fetches. It doesn't always happen
because some cases clear the cache, however I can consistently trigger
it by creating and deleting an account a few times in a row.
Android allows only having one address book per account, so until now
users of EteSync were only able to have one address book. This was
always an annoying limitation, but even more so now that journal sharing
is implemented.
Luckily, DAVdroid recently implemented multiple account support by
creating sub-accounts for address books.
This patch is an import of the DAVdroid changes, with adjustments to
work with EteSync, and a few changes that did not make sense for
EteSync. The original commits' split didn't provide any value over this
squash, and the amount of adjustments and addition needed to be done to
apply them, made me decide to squash this change together.
This commit is mostly based on:
dfec72ce6b8ff5e0780e9ac4418c81d080f4b60b
9817594da14ad8dffae18de386e14aeaf41312b9
This change only works for calendars at the moment, because we don't have shared
address books anyway.
This is currently only implemented in the client, and only as a read-only attribute,
you can't make a journal read-only yet. This requires server support that is not yet
there, but it's better to be ready for this sooner rather than later.
Some of the information is now saved there, and more will be transferred
soon. CollectionInfo includes the encrypted part, and journalentity the
non-encrypted part of the journal info, so both are needed.
We were storing the ctag separately although the data was already
present in the journal. The last entry's ID is always the CTAG.
This could cause issues if sync is aborted exactly at the right time.
I managed to trigger this issue on rare cases.
* move file name/UID generation from SyncManager to LocalContact, LocalEvent, LocalTask
* rename updateFileNameAndUID() to prepareForUpload()
* use random UUID for contacts, UidGenerator with Android device ID for events/tasks
* LocalEvent.prepareForUpload(): use existing UID_2445 if available
Commit 5d1c90dcba fixed a bug where
entries added from the server were marked as "local only" (null etag)
which was causing issues. That commit fixes it for newly added resources,
but existing resources remained broken.
This commit goes through the database and fixes all of the existing
broken resources. It skips dirty entries because figuring out if they
were just created or updated is complex, and the chances of doing an
update at exactly the same time there are dirty entries is quite low,
so the complexity involved is just not worth it.
I was trying to avoid it, and keep it as davdroid both for attribution,
and making it easy to cherry-pick fixes from DAVdroid.
However, it seems to be causing clashes with the davdroid app, although
every piece of documentation claims otherwise.[1]
At least it seems like cherry-picks can still be achieved using:
git cherry-pick -s recursive -X find-renames=30 COMMIT
