ipfs-cluster-service now has a migration subcommand that upgrades
persistant state snapshots with an out-of-date format version to the
newest version of raft state. If all cluster members shutdown with
consistent state, upgrade ipfs-cluster, and run the state upgrade command,
the new version of cluster will be compatible with persistent storage.
ipfs-cluster now validates its persistent state upon loading it and exits
with a clear error in the case the state format version is not up to date.
Raft snapshotting is enforced on all shutdowns and the json backup is no
longer run. This commit makes use of recent changes to libp2p-raft
allowing raft states to implement their own marshaling strategies. Now
mapstate handles the logic for its (de)serialization. In the interest of
supporting various potential upgrade formats the state serialization
begins with a varint (right now one byte) describing the version.
Some go tests are modified and a go test is added to cover new ipfs-cluster
raft snapshot reading functions. Sharness tests are added to cover the
state upgrade command.
Use docker to run ipfs
Improve intialization of daemons
Fix a bunch of tests
Improve run script
Make sure everything is shell-compatible (remove bash syntax)
Fit to run in travis
* Added travis sharness build
* ipfs-cluster-ctl help text width overflow fixed
* Expect success from fixed sharness test
* First travis-sharness PR touch up
Undoes gx rewrite of cluster-ctl dependencies
Undoess linebreaking of usage descriptions
Changes test to check for lines in excess of 120 chars instead of 80
run-sharness script now correctly tracks exit codes and exits with error
I have attempted to address all of the comments on the original PR.
The sharness tests now make use of prereqs, see test-lib for details
and helper functions.
