Summary: Previously, calling the IMAPConnectionPool `onDone` callback when checking out a connection would just return the connection to the pool without re-establishing it the next time we checked it out of the pool. When the `onDone` callback was called in an error scenario, this had the unintended consequence of returning a bad connection to the pool, and then re-using this bad connection. The only scenario when the connection was re-established was if `onConnected` threw an error, but if the connection was kept open outside the scope of onConnected, this logic would never run. To make things simpler and more consistent, `onDone` will always destroy all connections and connections will always be re-established from scratch every time they are checked out of the pool. The pool acts more as a limit to the number of connections per account, than an actual shared pool of connections.

Client Sync
This is the mail sync engine that runs within the Nylas Mail client
It is symlinked in as an internal_package
of Nylas Mail via the postinstall
script of the root repo.
Important Usage Notes:
Since this is symlinked in as an internal_package
of Nylas Mail, there are a
handulf of considerations when developing in client-sync. Some common gotchas:
- You MAY use
NylasEnv
,NylasExports
and other injected libraries in the Nylas Mail client environment. - You MAY use any 3rd party library declared in
client-app/package.json
. Since this gets added as a plugin of the Nylas Mail client, you'll have access to all libraries. This works because theclient-app/node_modules
was added to the global require paths. That lets us access client-app plugins without being a file directory decendent of client-app (client-sync is now a sibling of client-app) - You may NOT add "dependencies" to the
client-sync/package.json
. If you need a 3rd party library, add it to the mainclient-app/package.json
. All Nylas Mail plugins (those inside ofinternal_packages
), may no longer declare their own dependencies. - You should be aggressive at moving generic mail methods to
isomorphic-core
. We may eventually want to make large chunks of client-sync work in a cloud environment as well.
