Summary:
We've been syncing drafts messages but not the drafts flag in K2, making
them appear in Edgehill as regular old messages.
This commit makes K2 sync the drafts flag, and also correctly label
folders called "Drafts" with the 'drafts' role.
Because 2-way syncing of drafts is very complex and error-prone since
you need to add new drafts and delete the old ones on every update, and
we reaally don't want to do things like create multiplying draft copies
or accidentally lose a draft someone started composing elsewhere, we
simply exclude messages marked as drafts from being serialized to
Edgehill through the delta stream for now. This removes the confusing
behaviour and also sets a better stage for completing drafts sync later.
Eventually we will also want to add functionality to allow users to
select their drafts folder, but for now this code does the right thing
in many more cases.
While investigating this behaviour, I also discovered a bug we've never
seen before where Gmail isn't applying the \Draft flag to draft
messages, no matter which folder we fetch them from. :-/ This is very
unfortunate and there's no way for us to work around it other than to
fetch messages in the Drafts folder and manually apply the flag locally,
since "drafts" is not a label in Gmail, only another IMAP folder. Brandon
Long from the Gmail team says that this is because they've had
problems with clients which sync drafts, so the Gmail web client and
mobile apps do not set the \Draft flag on drafts. (I don't get how this
solves their problem, but okay.) Let's solve the issue on Gmail if it
comes up by user demand—should be relatively straightforward to
implement, but it adds sync work & complexity.

Summary:
This commit makes it so our syncback tasks send as few imap commands as possible by passing a set of UIDs whenever possible. Previously, we would send 1 command per message, with a single UID, which was very wasteful given that we can pass a set of UIDs. This is especially helpful for operating on threads with a large number of messages.
Syncback actions will now group all messages in a thread by the folder they belong to, and issue a single operation on the folder box. When removing all labels from a thread (setting labels to []), we need to issue a command of the form `box.delLabels(uids, labels)`, so we also group messages by set their set of labels to issue as few commands as possible.
This commit only batches imap commands, but we can still batch syncback actions themselves, which can be implemented in a separate patch.

Before this commit, if folder sync was complete, and the account didn't support CONDSTORE (e.g. Office365, Yahoo), we would only check for attribute updates every 10 minutes.
This commit makes it so we always check for attribute updates if the server doesn't support CONDSTORE
So for example, when marking a thread as read, we would perform the optimistic update in N1, queue the syncback task which would succeed, but the thread in k2s db would never get updated and become stale, with an unreadCount > 0. If we emitted a delta for that thread during the window of time where we ignored attribute updates, it would be set as unread again in N1, even though all of its messages were read.
This still doesn't guarantee that it wont happen (we could still get a delta for the thread before we actually fetch the attribute updates from IMAP), but before this commit it was sure to happen. This should be properly fixed with the sync scheduler refactor

Previously, we were not pripritizing archive sync when getting folders to sync, causing it to be synced almost last. I believe this was causing the issues regarding archived items coming back, because we would optimistically archive in N1, but the changes wouldn't be reflected in K2's database until we synced the archive, causing the data to become out of sync. If for whatever reason we got a delta for any of those messages before the archive was synced, they would pop back in the inbox because in k2, they were still in the inbox. This was exacerbated by the fact that all syncback tasks would interrupt the loop, so we would reach the archive until very late, making this scenario way more likely.
This still wont guarantee that it wont happen, because we dont do /any/ optimistic updates in K2, so we could still get deltas before we actually sync the folder, but makes the scenario way less likely. This should be properly fixed with the sync scheduler refactor

This commit also lowers the batch size of messages to fetch on folder sync down to 30. This is in order to prevent sync from getting stuck if we queue too many syncback tasks-- given that we only update the range of fetched uids after we've actually fetched and processed messages, if the batch size is too big and we interrupt too often, we might end up never advancing the range and re fetching the same messages over and over.
This also makes the sync loop run faster through all folders in general.

Because we optimistically fetch UIDs by expanding a range without looking
at the actual UIDs in the inbox and the actual space of UIDs with messages
attached may be sparse due to message moves, we need to track how many
messages we actually download during a range expansion and continue
expanding the range if we haven't downloaded enough messages.
If we reach a large gap where we download no messages at all during a batch, we
pause and check the actual UID list for the folder for the next UID to
download, as otherwise we may spin indefinitely fetching UIDs that don't exist.
(Example: my "Deleted Items" folder had about 300k worth of empty UIDs between
a very small UID and a very large UID. With the new system, this registers as a
completed sync within a single iteration as soon as sync hits the gap.)

Currently, our mail sync strategy of expanding UID ranges from UIDNEXT
backwards until a UID of 1 implicitly assumes that every UID corresponds to an
actual message. This assumption is incorrect, and results in several
significant bugs regarding sync status.
This patch fixes issue 1:
Since UIDs are persistent and, so long as the UIDVALIDITY is valid, ascend
monotonically upward, every time you move a message to a new folder you "lose"
UIDs lower down in the range. In my work Inbox, where I get a lot of mail,
archive all the time, and generally have only a small number of threads in the
mailbox, the smallest UID is over 100k. This means that, after all my inbox
messages are synced, the sync loop will continue attempting to download
nonexistent old messages in this mailbox for hundreds of sync iterations, and
will not mark the mailbox as fully synced until fetchmin reaches 1, regardless
of the fact that there are no actually messages being pulled down.
This patch needs a small associated patch to N1 to update how sync status is
calculated (coming soon).
The next patch in this series will deal with gaps in the UIDspace that slow
down syncing of a folder.

This swaps out our generic IMAP threading mechanism to use the threading
headers on the message instead of the prior way of grouping by subject
and then differentiating based on participants, as that design was
somewhat driven by what we could accomplish easily given legacy data
schema decisions and has serious caveats, such as different threads between
the same people with the same subject being misthreaded together. With K2, we
have free reign to change the data format, so we can do it right.
The algorithm is super simple:
- Define "references" as the union of the Message-Id, In-Reply-To, and
References headers on a message, filtered for valid RFC2822 Message-IDs
- On message sync, if any element of the new message's references
matches any element of an existing message's references, thread them
together
In order to accomplish this, we need to store References in a way that
allows each element to be indexed for fast lookup. That meant either
using the sqlite JSON1 extension + expression-based indices, or creating
a new table. I chose the latter as a time-tested and simple solution,
since we don't need the flexibility of JSON here.

Summary:
Headers can be quite big, so we might as well download and store only
the ones that we care about. This patch also makes it so we stop
downloading MIME structures twice per message.
While it's possible that we _may_ want to make more headers accessible
later, we don't currently make the generic pile of headers accessible to
N1 or N1 plugins in any way, so doing that would end up requiring
changes to the sync code regardless. I think it's worth optimizing the
base experience rather than trying to predict what we may want in the
future. Plus, it seems more likely that we'll want to build future
extensibility using thread metadata, rather than message headers.

Summary:
It's possible to have multiple inline HTML parts in a message, or even
a multipart/alternative part that contains text and HTML, followed by a
plaintext signature. Previously, if there was more than one text part in
an email, we would pick the _last_ text/html or text/plain part that we
found, and treat that as the entire message body. This works most of the
time, but fails to display the full message body in some edge cases.
This patch fixes that by resolving multipart/alternative subparts to a
single part in the mimepart fetch stage, and then treating each desired
mime part separately when parsing the message, concatenating them if
there are multiple.
This makes K2's handling of multipart MIME message text better,
bug-wise, than the Python sync engine's, which has been mangling some
rare messages forever. (Example from my email: every email from the MIT
EECS Jobs List has never displayed the mailing list signature in N1.)
Note that this patch also removes our tentative support for PGP
encrypted messages. I'd rather add that back in later when I've dug up
some real example messages to test on, rather than leaving it in in its
current not-really-tested and probably not-really-working state, since
it makes it harder to make sure that the rest of the logic isn't broken.

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.

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.

the DOM walking process once we've accumulated enough text to create

the new implementation is something like 10-100x faster for some messages.

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`.

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

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

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.
I didn't want to upgrade our sequelize version right now and cause of bunch of mysterious failures, so I've simply changed the `UPSERT` to be either an `INSERT`or `UPDATE`. We didn't really need it anyway.

Also renames JSONType() -> buildJSONColumnOptions() and
JSONARRAYType() -> buildJSONARRAYColumnOptions() to prevent passing
those return values in as just the type value instead of the entire
options object.
Since message IDs are now static but there's no good way to generate
static thread IDs while syncing an account from newest message first,
we give threads the ID of any message on that thread and, when setting
metadata, look up the local thread ID by first going through the
message table.
- Don’t need functions in delta.js which must be called to return promsies. Fun of promsies is that you don’t need to care when they’re built to attach a .then.
- Make boundary between route handler and delta stream builder more explicit, don’t do query parsing in helpers, always reply from handler.
- Remove pushJSON extension to outputStream which never actually received JSON.
- Remove `takeUntil` - disposing of the downstream observable should dispose of all the merged/upstream observables
- Rename inflate => stringify since the returned value is a string not an object.
- Remove support for delta streams with no cursors. Don’t think this was supposed to be a feature.
- Add accountId to Transaction models
- Make database hooks shared in isomorphic core
Summary:
T7253 has two related parts:
1. Stripping the '[Gmail]/' prefix from any canonical Gmail folders
2. Handling nested IMAP folders.
This diff fixes 1. Changes for 2. are forthcoming.
Test Plan: Tested manually. Checked that the part was stripped from the N1 folder list.

Moving to between gmail folders (all, spam, trash) or moving to inbox,
involves changing labels /and/ folders, simultaneously. For this I added
a task to perform both operations, and apply labels first before
attempting to move the folder
This also ensures that we can use the accountId as part of the ids for
other models, like labels and folders
Before this commit, labels and folders with the same name for different
accounts would have the same id, screwing things up in n1
