fix: kill all tlogs in one region prevents the remote logs from recovering in that region, do not allow that to prevent us from configuring usable_regions=1.

added more recovery states.

fix: during upgrades, a storage server which does not have data for a shard could be in the source servers, so as a fallback if a fetch keys fails long enough disable locality based load balancing to allow the storage server to peek from someone different than itself

Add metrics for watches and mutations on the storage server. The storage server tracks its lag with the logs, and status tries to report a more accurate measure of this lag.

Some more trace event normalization
2018-06-08 13:57:00 -07:00
e5488419cc
Attempt to normalize trace events:
...
* Detail names now all start with an uppercase character and contain no underscores. Ideally these should be head-first camel case, though that was harder to check.
* Type names have the same rules, except they allow one underscore (to support a usage pattern Context_Type). The first character after the underscore is also uppercase.
* Use seconds instead of milliseconds in details.
Added a check when events are logged in simulation that logs a message to stderr if the first two rules above aren't followed.
This probably doesn't address every instance of the above problems, but all of the events I was able to hit in simulation pass the check.

fix: do not finish a shard relocation until all of the storage servers have made the current recovery version durable. This is to prevent dropping a needed storage server as a source for a shard after dropping a remote configuration

fix: do not allow a storage server to be removed within 5 million versions of it being added, because if a storage server is added and removed within the known committed version and recovery version, they storage server will need see either the add or remove when it peeks

locality aware load balancing was disabled on the storage servers because emergency teams might cause a server to be assigned a shard when it does not actually have the data. This problem has been fixed, so we can re-enable locality aware load balancing.
