Alex Dadgar 8504505c0d client uses passed logger and fix fingerprinters 2018-10-16 16:53:30 -07:00
Michael Schurter 9d1ea3b228 client: hclog-ify most of the client 
Leaving fingerprinters in case that interface changes with plugins.

Michael Schurter e42154fc46 implement stopping, destroying, and disk migration 
* Stopping an alloc is implemented via Updates but update hooks are
  *not* run.
* Destroying an alloc is a best effort cleanup.
* AllocRunner destroy hooks implemented.
* Disk migration and blocking on a previous allocation exiting moved to
  its own package to avoid cycles. Now only depends on alloc broadcaster
  instead of also using a waitch.
* AllocBroadcaster now only drops stale allocations and always keeps the
  latest version.
* Made AllocDir safe for concurrent use

Lots of internal contexts that are currently unused. Unsure if they
should be used or removed.

Michael Schurter 4236255686 lots of comment/log fixes 2018-10-16 16:53:30 -07:00
Michael Schurter 357641c364 persist alloc state on changes, not periodically 
Allow alloc and task runners to persist their own state when something
changes instead of periodically syncing all state.

Michael Schurter a3fe0510d1 Move all encoding and put deduping into state db 
Still WIP as it does not handle deletions.

Michael Schurter a5d3e3fb0a Implement alloc updates in arv2 
Updates are applied asynchronously but sequentially
 2018-10-16 16:53:30 -07:00
Michael Schurter a4b4d7b266 consul service hook 
Deregistration works but difficult to test due to terminal updates not
being fully implemented in the new client/ar/tr.

Michael Schurter 516d641db0 client: implement all-or-nothing alloc restoration 
Restoring calls NewAR -> Restore -> Run

NewAR now calls NewTR
AR.Restore calls TR.Restore
AR.Run calls TR.Run

Michael Schurter 0f7dcfdc9a example redis job "runs" on arv2! see below 
Tons left to do and lots of churn:
1. No state saving
2. No shutdown or gc
3. Removed AR factory *for now*
4. Made all "Config" structs local to the package they configure
5. Added allocID to GC to avoid a lookup

Really hating how many things use *structs.Allocation. It's not bad
without state saving, but if AllocRunner starts updating its copy things
get racy fast.

Alex Dadgar f24ce2c50c Driver health detection cleanups 
This PR does:

1. Health message based on detection has format "Driver XXX detected"
and "Driver XXX not detected"
2. Set initial health description based on detection status and don't
wait for the first health check.
3. Combine updating attributes on the node, fingerprint and health
checking update for drivers into a single call back.
4. Condensed driver info in `node status` only shows detected drivers
and make the output less wide by removing spaces.

Handle the ErrNoLeader case and apply slower retries. Also when we have

missed for more than 30 seconds.
