Richard van der Hoff e13c6c7a96 Handle one-word replication commands correctly
`REPLICATE` is now a valid command, and it's nice if you can issue it from the
console without remembering to call it `REPLICATE ` with a trailing space.

Richard van der Hoff c3e4b4edb2 Fix warnings about not calling superclass constructor
Separate `SimpleCommand` from `Command`, so that things which don't want to use
the `data` property don't have to, and thus fix the warnings PyCharm was giving
me about not calling `__init__` in the base class.

Richard van der Hoff 6a519a0ca0 Remove vestigal references to SYNC replication command
We've ripped pretty much all of this out: let's remove the remains.

Fix race in replication (#7226)
Fixes a race between handling `POSITION` and `RDATA` commands. We do this by simply linearizing handling of them.

Move server command handling out of TCP protocol (#7187)
This completes the merging of server and client command processing.

Move client command handling out of TCP protocol (#7185)
The aim here is to move the command handling out of the TCP protocol classes and to also merge the client and server command handling (so that we can reuse them for redis protocol). This PR simply moves the client paths to the new `ReplicationCommandHandler`, a future PR will move the server paths too.

Remove connections per replication stream metric. (#7195)
This broke in a recent PR (#7024) and is no longer useful due to all
replication clients implicitly subscribing to all streams, so let's
just remove it.

Erik Johnston 4f21c33be3
Remove usage of "conn_id" for presence. (#7128)
* Remove `conn_id` usage for UserSyncCommand.

Each tcp replication connection is assigned a "conn_id", which is used
to give an ID to a remotely connected worker. In a redis world, there
will no longer be a one to one mapping between connection and instance,
so instead we need to replace such usages with an ID generated by the
remote instances and included in the replicaiton commands.

This really only effects UserSyncCommand.

* Add CLEAR_USER_SYNCS command that is sent on shutdown.

This should help with the case where a synchrotron gets restarted
gracefully, rather than rely on 5 minute timeout.

Erik Johnston 4cff617df1
Move catchup of replication streams to worker. (#7024)
This changes the replication protocol so that the server does not send down `RDATA` for rows that happened before the client connected. Instead, the server will send a `POSITION` and clients then query the database (or master out of band) to get up to date.

Fix ClientReplicationStreamProtocol.__str__ (#4929)

anyway.

2019-02-26 15:12:33 +00:00
Erik Johnston 313987187e Fix tightloop over connecting to replication server
If the client failed to process incoming commands during the initial set
up of the replication connection it would immediately disconnect and
reconnect, resulting in a tightloop.

This can happen, for example, when subscribing to a stream that has a
row that is too long in the backlog.

The fix here is to not consider the connection successfully set up until
the client has succesfully subscribed and caught up with the streams.
This ensures that the retry logic timers aren't reset until then,
meaning that if an error does happen during start up the client will
continue backing off before retrying again.

Richard van der Hoff 0e8d78f6aa Logcontexts for replication command handlers
Run the handlers for replication commands as background processes. This should
improve the visibility in our metrics, and reduce the number of "running db
transaction from sentinel context" warnings.

Ideally it means converting the things that fire off deferreds into the night
into things that actually return a Deferred when they are done. I've made a bit
of a stab at this, but it will probably be leaky.
