This reverts commit 0b3e3d2f39.
Interrupting sync by closing connection causes errors downstream when
`syncNow` is called elsewhere. Instead of interrupting by closing the
connection, we will post a patch to interrupt the sync loop properly
Summary:
Sync operations are mostly bound by I/O and the imap connection.
What we believe that is mostly affecting cpu and battery life is that node’s event
loop is being hosed with cpu intensive message processing operations.
To alleviate this, we do a few things:
- Restore a global message processing queue to process messages serially and meter cpu usage (message processing continues to be a fire and forget call from within sync operations)
- Move actual cpu intensive work to the message processing queue, i.e. `MessageFactory.parseFromImap`
- Keep track of message processing queue length, and skip sync operations if queue is too big to prevent massive memory consumption
This commit also renames the package from new-message-processor to
message-processor, given that now it processes both new and existing
messages, and we like to minimize confusion.

Summary:
refactor multi-send
This diff started off by fixing sending with attachments.
The issue is that our `FileUploadStore` listened for
`Actions.sendDraftSuccess` as its signal to remove the files from the
.nylas temp directory. Unfortunately, the old MultiSend tasks, after
delivery of the message, would try and put the base message in the sent
folder. Since we already deleted the file from our local temp dir,
creating the base message for the sent folder would fail.
This exposed a much bigger issue which is that we don't consistently
distinguish between "delivery" of a message and any post-processing we do
(like filling the sent folder). This was leading to a variety of other
subtle issues.
For example, N1 assumes that if the SendMessage task fails, then we pop
the draft back up and ask the user to try again. Unfortunately, since we
were combining "delivery" and "post processing" it was possible for the
message to actually deliver, but fail when stuffing the sent folder, or
fail due to some other random bug. This would cause the user to send the
message twice.
To help us ensure we never "deliver" twice and handle errors more
intuitively, I separated out the two concepts.
Now there are "send" set of tasks and endpoints, and a
"EnsureMessageInSentFolder" set of tasks and endpoint (the latter used to
be ambiguously known as ReconcileMultiSend, whatever that meant)
The logic for send hasn't changed. This is mostly a renaming and moving
files around.

Contrary to what you might think, a message can have both an empty From: header

we must save all of them and let the client decide how to display.

Summary: I've found a pretty annoying bug --- N1 would stop syncing all accounts after the Internet connection dropped.

Summary:
Because of JavaScript's asynchronous nature, it is possible that we will
be processing several downloaded messages concurrently. This can lead to
calling extractContacts() in an interleaved fashion, which it was not
designed to handle. It looks up which contacts are already in the
database and then performs inserts or updates accordingly, assuming
nothing has changed in the contacts table in between---which is not
true! If several messages have similar contacts, an insert race can
cause one of the inserts to throw an unhandled exception.
We fix this by simply catching the unique constraint error, and falling
back to an update instead. (There's not really a better way to deal
with write races other than to enforce that we process contacts from
messages serially, as transactions are of no help here.)
This commit also removes extractContacts()'s return value, which is not
currently used and I found confusing.

This issue was causing us constantly run the sync loop without pauses,
i.e. every next sync loop was scheduled immediately.
Currently, when we receive a new `'mail'`event, we trigger a new sync loop. Previously, when this happened while a sync loop was already in progress we would just ignore the event. However, my recent patch keeps track of how many times we tried to start a sync loop while one was already in progress. If the number of times this happens is > 0, it will schedule the next sync loop immediately (as opposed to waiting a constant amount seconds before the next loop).
The problem is that this new logic is making the sync worker always schedule the next sync loop immediately (without pausing for a few seconds). This is due to the following chain of events (assume we are just syncing `all` and `trash` folders):

This is a small patch but it's pretty complex, because of the numbers of moving parts. Gmail has two types of tokens, access and refresh tokens. Access tokens have a limited shelf life of one hour. After that they expire and you need to use your refresh token to get a new one.
We've decided to do the access token generation on the server, because we don't feel comfortable giving our users both our Google client id and secret. To do that, I've added an endpoint, `/gmail/auth/refresh` which returns a valid access token as well as an expiration date for the token.
The only place where we handle token expiration is in the sync workers. Before trying opening a new connection we check if our access token is expired. If yes, we get a new one from the API. If there's an issue doing this, we notify N1 using `NylasAPIHelpers.handleAuthenticationFailure`.

Add internal state to the sync worker to allow for it to be interrupted

The concept in this commit is that if we've tried to trigger a sync enough times
while its already in progress, bail and start over.
Usually, we manually trigger sync loops when we queue a new SyncbackTasks,
so that the newly queued task gets executed. This is necessary because the only
way to run SyncbackTasks is via the sync loop, for consistency and simplicity
reasons.
For example, we might run into a case where we queue a SendMessage task,
and we want it to be executed ASAP, but if we're in the middle of a
syncing a mailbox with a ton of folders, we wont get to the SendMessage
task after some considerable time.
Specifically this commit makes it so:
- If the number of sync attempts while in progress is > 0, make sure we schedule the next sync immediately
- If we reach a threshold of sync attempts while in progress, interrupt sync and restart

Initially, the problem that led to this diff was generating message ids that
wouldn't collide (which was causing errors in the message-processor). Collisions
in ids were being caused by messages that contained the exact same participants,
subject and date (most likely due bots or scripts sending emails in quick
succession)
To prevent collisions this commit adds the `message-id` header as part of the
database message id, and ensures that we set it correctly before sending, and
that it remains consistent through send, multi-send, and the sync loop.
During the refactor and review, I removed some code that assumed that we were
syncing drafts (which we aren't), and also fixes a few other known and
unknown issues around sending, message creation, and tracking, like assigning
the correct date header (we were previously assigning the draft creation date

When running syncback requests, if a task is meant to change the UID of
a message (e.g. move it to a new folder), that task should be run after
other tasks that don't affect the UID. Otherwise, when trying to run the
other tasks, they would reference a UID that is no longer valid.
This commit will make sure that we run any tasks that will change message uids last,
/and/ make sure that we don't run more than 1 task that will affect the uids of
the same messages in a row (i.e. without running a sync loop in between)
This commit will correctly keep track of folder and label ids when
creating them from N1.
Previously, when we sent the request to create a folder or label to our api,
we would immediately get back a serverId because it was created optimistically
in the back end— given that K2 is strictly non-optimistic, we won’t have a serverId
until some undetermined time in the future, and we need to somehow reference
the object that /was/ optimistically created in N1 to update the ui when
we do get the server id.
Since we can deterministically generate ids for folders and labels,
we "guess" what its going to be, and include it in the props of the syncback request
returned to N1. This is the simplest solution to get thing working
correctly right now, but we’ll need to revisit this in the future for
other types of objects (drafts, contacts, events), and revisit how we
will manage optimistic updates in N1 when we merge the 2 codebases
with K2 (given that K2 was designed to be non-optimisitc).
Summary:
Fixes T7283. We weren't creating deltas for contacts because we were inserting contacts using `UPSERT`, which requires us to add another sequelize hook. Unfortunately, support for this hook is only available on sequelize 4.x.
