Christine Spang 359e32282f [local-sync] Sync draft flag from provider to K2 & exclude drafts from Edgehill
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.

K2 - Local Sync Engine & Cloud Services for Nylas Mail

This is a collection of all sync and cloud components required to run N1.

  1. Cloud API: The cloud-based auth and metadata APIs for N1
  2. Cloud Core: Shared code used in all remote cloud services
  3. Cloud Workers: Cloud workers for services like send later
  4. Isomorphic Core: Shared code across local client and cloud servers
  5. Local Sync: The local mailsync engine integreated in Nylas Mail

See /packages for the separate pieces. Each folder in /packages is designed to be its own stand-alone repositoriy. They are all bundled here for the ease of source control management.

Initial Setup for All Local & Cloud Services:

New Computer (Mac):

  1. Install Homebrew
  2. Install NVM brew install nvm
  3. Install Node 6 via NVM: nvm install 6
  4. Install Redis locally brew install redis

New Computer (Linux - Debian/Ubuntu):

  1. Install Node 6+ via NodeSource (trusted):
  2. curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
  3. sudo apt-get install -y nodejs
  4. Install Redis locally sudo apt-get install -y redis-server redis-tools benefit of letting us use subdomains.
