Evan Tschannen ccaa860ffc fix: all storage servers must reboot during a forced recovery, because their rejoin commit might have been lost 2019-02-18 15:27:18 -08:00
Evan Tschannen 9cfadad41b fix: if the tagPartitionedLogSystem cannot do a forced recovery, the master should not execute it forced recovery based modifications either 2019-02-18 15:13:18 -08:00
Evan Tschannen 8f2af8bed1 fix: forced recoveries now require a target dcid which will become the new primary location. During the forced recovery, the configuration will be changed to make that location primary, and usable_regions will be set to 1. If the target dcid is already the primary location, the forced recovery will do nothing. This makes forced recoveries idempotent, so it is safe to the client to re-send forced recovery commands to the cluster controller.
fix: the cluster controller attempts to do a commit to determine if the cluster is alive, since its own internal recoveryState might not be up-to-date.

fix: forceMasterFailure on the cluster controller did not always cause the current master to be re-recruited
2019-02-18 14:54:28 -08:00
Evan Tschannen 4c35ebdcc6 fix: because of forced recoveries, storage servers in remote regions cannot update their durable version to (lastLogVersion - 5e6), because the lastLogVersion might have jumped due to an epoch end and the recovery version after the forced recovery could be before the epoch end, causing the storage server to want to rollback to a version it does not have on disk 2019-02-18 14:40:30 -08:00

Jingyu Zhou aea602d9c7 Remove getRecoveryInfo from master interface. 2019-02-14 16:37:16 -08:00
Jingyu Zhou 886e7ab2ba Add a new DataDistributor role.
Let cluster controller to start a new data distributor role by sending a
message to a chosen worker.
Change MasterInterface usage in DataDistribution to masterId

Add DataDistributor rejoin handling.

This allows the data distributor to tell the new cluster controller of its
existence so that the controller doesn't spawn a new one. I.e., there should
be only ONE data distributor in the cluster.

If DataDistributor (DD) doesn't join in a while, then ClusterController (CC) tries
to recruit one as DD. CC also monitors DD and restarts one if it failed.

The Proxy is also monitoring the DD. If DD failed, the Proxy will ask CC for
the new DD.

Add GetRecoveryInfo RPC to master server, which is called by data distributor
to obtain the recovery Transaction version from the master server.

Robert Escriva 268093a96d Adjust all includes to be relative to the root.
Remove the use of relative paths.  A header at foo/bar.h could be included by
files under foo/ with "bar.h", but would be included everywhere else as
"foo/bar.h".  Adjust so that every include references such a header with the
latter form.

Evan Tschannen 866ccfe344 added the ability to allow the master to finish recovery before all storage servers in both regions have their mutations. This allows you to recover from scenarios where you lose all your tlogs in one dc. 2018-07-04 01:59:04 -04:00

We will not recruit in DCs with negative priority.

Alex Miller fcfa00928b Make RecoveryState an enum class.
This means that all the == 7 or != 0 checks go away, and explicit names must be used.
2018-06-12 16:50:25 -07:00
A.J. Beamon 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.

Alex Miller f70e3b9fe8 Add or change a bunch of comments to provide descriptions of function contracts.
This cleans up a bit of the VersionStamp DR work I did, and leaves hints and
advice for anyone who will be touching mutation applying code in the future.
2017-12-20 16:57:14 -08:00
Alex Miller b5a6bc0ab7 Fix VersionStamp problems by instead adding a COMMIT_ON_FIRST_PROXY transaction option.
Simulation identified the fact that we can violate the
VersionStamps-are-always-increasing promise via the following series of events:

1. On proxy 0, dumpData adds commit requests to proxy 0's commit promise stream
2. To any proxy, a client submits the first transaction of abortBackup, which stops further dumpData calls on proxy 0.
3. To any proxy that is not proxy 0, submit a transaction that checks if it needs to upgrade the destination version.
4. The transaction from (3) is committed
5. Transactions from (1) are committed

This is possible because the dumpData transactions have no read conflict
ranges, and thus it's impossible to make them abort due to "conflicting"
transactions.  There's also no promise that if client C sends a commit to proxy
A, and later a client D sends a commit to proxy B, that B must log its commit
after A.  (We only promise that if C is told it was committed before D is told
it was committed, then A committed before B.)

There was a failed attempt to fix this problem.  We tried to add read conflict
ranges to dumpData transactions so that they could be aborted by "conflicting"
transactions.  However, this failed because this now means that dumpData
transactions require conflict resolution, and the stale read version that they
use can cause them to be aborted with a transaction_too_old error.
(Transactions that don't have read conflict ranges will never return
transaction_too_old, because with no reads, the read snapshot version is
effectively meaningless.)  This was never previously possible, so the existing
code doesn't retry commits, and to make things more complicated, the dumpData
commits must be applied in order.  This would require either adding
dependencies to transactions (if A is going to commit then B must also be/have
committed), which would be complicated, or submitting transactions with a fixed
read version, and replaying the failed commits with a higher read version once
we get a transaction_too_old error, which would unacceptably slow down the
maximum throughput of dumpData.

Thus, we've instead elected to add a special transaction option that bypasses
proxy load balancing for commits, and always commits against proxy 0.  We can
know for certain that after the transaction from (2) is committed, all of the
dumpData transactions that will be committed have been added to the commit
promise stream on proxy 0.  Thus, if we enqueue another transaction against
proxy 0, we can know that it will be placed into the promise stream after all
of the dumpData transactions, thus providing the semantics that we require:  no
dumpData transaction can commit after the destination version upgrade
transaction.
