Kyle Havlovitz c6f461aa25 Enable snapshots in dev mode (#2453) 2016-10-31 14:39:47 -04:00
James Phillips bc29610124 Adds support for snapshots and restores. (#2396)
* Updates Raft library to get new snapshot/restore API.

* Basic backup and restore working, but need some cleanup.

* Breaks out a snapshot module and adds a SHA256 integrity check.

* Adds snapshot ACL and fills in some missing comments.

* Require a consistent read for snapshots.

* Make sure snapshot works if ACLs aren't enabled.

* Adds a bit of package documentation.

* Returns an empty response from restore to avoid EOF errors.

* Adds API client support for snapshots.

* Makes internal file names match on-disk file snapshots.

* Adds DC and token coverage for snapshot API test.

* Adds missing documentation.

* Adds a unit test for the snapshot client endpoint.

* Moves the connection pool out of the client for easier testing.

* Fixes an incidental issue in the prepared query unit test.

I realized I had two servers in bootstrap mode so this wasn't a good setup.

* Adds a half close to the TCP stream and fixes panic on error.

* Adds client and endpoint tests for snapshots.

* Moves the pool back into the snapshot RPC client.

* Adds a TLS test and fixes half-closes for TLS connections.

* Tweaks some comments.

* Adds a low-level snapshot test.

This is independent of Consul so we can pull this out into a library
later if we want to.

* Cleans up snapshot and archive and completes archive tests.

* Sends a clear error for snapshot operations in dev mode.

Snapshots require the Raft snapshots to be readable, which isn't supported
in dev mode. Send a clear error instead of a deep-down Raft one.

* Adds docs for the snapshot endpoint.

* Adds a stale mode and index feedback for snapshot saves.

This gives folks a way to extract data even if the cluster has no
leader.

* Changes the internal format of a snapshot from zip to tgz.

* Pulls in Raft fix to cancel inflight before a restore.

* Pulls in new Raft restore interface.

* Adds metadata to snapshot saves and a verify function.

* Adds basic save and restore snapshot CLI commands.

* Gets rid of tarball extensions and adds restore message.

* Fixes an incidental bad link in the KV docs.

* Adds documentation for the snapshot CLI commands.

* Scuttle any request body when a snapshot is saved.

* Fixes archive unit test error message check.

* Allows for nil output writers in snapshot RPC handlers.

* Renames hash list Decode to DecodeAndVerify.

* Closes the client connection for snapshot ops.

* Lowers timeout for restore ops.

* Updates Raft vendor to get new Restore signature and integrates with Consul.

* Bounces the leader's internal state when we do a restore.

Makes empty checkServiceNode return a nil.
The change in #2308 had an inadvertent interface change, so we fix that with
a special case in this fix.

Stops scaling the commit timeout. 2016-08-25 15:05:40 -07:00
James Phillips f65ef936cb
Increases RPC hold timeout for new default timing.
Rather than scale this we just bump it up a bit. It'll be on the edge in
the lower-performance default mode, and will have plenty of margin in the
high-performance mode. This seems like a reasonable compromise to keep the
logic here simple vs. scaling, and seems inline with the expectations of
the different modes of operation.

This required a small mod to core Consul code to cope with an interface
change.

Switches all ACL caches to 2Q. 2016-08-09 11:00:22 -07:00
James Phillips 1e75fa0362
Moves ACL ID generation down into the endpoint.
We don't want ACL replication to have this behavior so it was a
little dangerous to have in the shared helper function.

James Phillips 06a510a808
Removes unsafe "recover to empty" code.
This isn't safe because it would implicitly commit all outstanding log
entries. The new Raft library already has logic to not start a vote if
the current node isn't in the configuration, so this shoudn't be needed.
