For every update sent to gluon wait and check the error code to see if
an error occurred.
Note: Updates can't be inspect on the call site as it can lead to
deadlocks.
Prevent infinite error loop in event parsing by not returning errors if
we already have or do not have a given address. This occurs since we
sync the latest state at Bridge startup but still receive the events
which contain these changes later.
Do not treat unknown label creation/deletion/update or deletion in Bridge
as an error as the Gluon cache still needs to receive these events to
correct its internal state.
During sync a user may continue to perform operations on the server it
is possible we run into a message which has a labelID we are not aware
of. To counter this we issue `CreateMessage` updates with
`IgnoreUnknownMailboxIDs` set to true. Eventually, after sync the state
will resolve itself with events.
Add special case handling for draft messages so that if a Draft is
updated via an event it is correctly updated on the IMAP client via a
the new `imap.MessageUpdated event`.
This patch also updates Gluon to the latest version.
Only delete messages when unlabeled from trash/spam if they only exists
in All Mail and (spam or trash).
This patch also ports delete_from_trash.feature and use status rather
than fetch to count messages in a mailboxes.
This change implements safe.Mutex and safe.RWMutex, which wrap the
sync.Mutex and sync.RWMutex types and are assigned a globally unique
integer ID. The safe.Lock and safe.RLock methods sort the mutexes
by this integer ID before locking to ensure that locks for a given
set of mutexes are always performed in the same order, avoiding
deadlocks.
Labels can be held locally and updated in memory. This greatly improves
the responsiveness of IMAP mailbox operations as we don't need to fetch
all a user's labels to find the parent whenever a mailbox is moved.
This fixes various race conditions and leaks related to the user's sync
and API event stream. It was possible for a sync/stream to begin after a
user was already closed; this change prevents that by managing the
goroutines related to sync/stream within cancellable groups.
Add missing Close calls.
Properly handle nil channel for `user.startSync`.
This patch also updated liteapi and Gluon to latest master and dev
version respectively.
We need to unlock the user keyring anyway to unlock the address keyring,
so we should just return it instead of re-unlocking the user keyring
when sending a message.
