Update to latest Gluon to allow access to the database for bridge. The
cache is placed in a `SharedCache` type to ensure that we respect calls
to `Connector.Close`.
In theory, this should never trigger an error, but this way we can catch
it if it happens.
https://github.com/ProtonMail/gluon/pull/391
Add two separate toggles to control event loop pausing. This is required
to prevent cases where the bridge requests the event loop to be paused
but a sync process completes and resumes the event loop.
For the loop to resume now both states need to be set to false. This
will be removed once GODT-2848 is implemented.
Wait for the current event poll to finish publishing events after a
request to pause the event loop. This is required to change the gluon
cache directory.
Rather than having the services subscribe to each individual event type,
have only one subscriber for the whole event object. This spreads the
logic to the service through the `EventHandler` type.
This is important for the next stage where the IMAP service will be
required to apply events from the past.
Handles all IMAP related tasks. Unlike the previous iteration, this new
service automatically adds and removes users from Gluon by interfacing
with server manager.
Add `OrderedCancelGroup` type to enforce the cancellation of go routines
in a reverse order. Additionally this type waits for the go-routine to
finish before proceeding to the next one.
We need this to guarantee that all the user services shut down properly
without deadlocking.
This patch moves the `user.User.CheckAuth` function into the `State`
type as it contains all the necessary information to perform this check.
A couple of more interfaces are added to abstract the retrieval of the
Bridge and the User's key passwords, as well as telemetry reports.
Finally, adds `State.OnAddressEvents` which other services should use to
update the state.
Identity Service contains all the information related to user state,
addresses and keys.
This patch also introduces the `State` type which can be used by other
services to maintain their own copy of this state to avoid lock
contention.
Finally, there are currently no external facing methods via a CPC
interface. Those will added as needed once the refactoring of the
architecture is complete.
This patch adds the User Event Service which is meant to replace the
current event polling flow.
Each user interested in receiving events should register a new
subscriber using the `Service.Subscribe` function and then react on
the incoming events.
The current patch does not hook this up Bridge user as there are no
existing consumers, but it does provide extensive testing for the
expected behavior.
Rather than accessing the Bridge user list, each user register their
individual SMTP service with the server manager.
Note that some dependencies on the user data are hidden behind the
`UserInterface`. These will be removed in a future patch.
Refactor code to isolate the SMTP functionality in a dedicated SMTP
service for each user as discussed in the Bridge Service Architecture
RFC.
Some shared types have been moved from `user` to `usertypes` so that
they can be shared with Service and User Code.
Finally due to lack of recursive imports, the user data SMTP needs
access to is hidden behind an interface until the User Identity service
is implemented.
