- blue_green for doing migration. Called before Holder.Open finishes.
- holdbkg.go added for index lookup. Less wedging between a deadlock and a race.
- fix fault under read-only map under lmdb at
TestExecutor_Execute_Row_Range/RowIDColumnID by doing cow in roaring.
- roaring -tags gofuzz builds again
- roaringparanoia build tag added to make test targets in Makefile
- add rbf.NewDBWithAllocZero for out-of-bounds memory checks
- .circleci/config.yml test-shardwidth-22 with large run container, kept OOM-ing we suspect.
Fixes#819
The testhook/ package provides an easy way to set up multiple
hooks to run before/after tests are run.
The audit hooks track open and closes of storage backends,
files, indexes, and holders, for example. A tempdir wrapper
creates temporary directories which are automatically cleaned up
when the test ends. Any kind of resource creation that
should be closed at test conclusion can be tracked. We
will complain at the end of the TestMain if resources are
leaking.
Leaks under go1.13:
We use a wrapper function which is a no-op for go 1.13, but actually
calls testing.TB.Cleanup in go1.14, so we can still build with 1.13 even though
tests will leak files all over the place there. Because of this,
don't run the testhook tests when using 1.13, as they'll always fail.
- the test/pilosa.go http client now times out after 10 seconds
to help diagnose hung server situations.
- Makefile targets added to get better progress reports.
This commit adds support for advertise address by using a new config
option `advertise`, or by defaulting its value to that
specified in `bind`.
Also adds support for listening on 0.0.0.0 by trying to determine
the preferred outbound IP to use for the advertise address.
I'd like to add stat tracking to Roaring, which means it
has to be able to import the stats package, which means
stats has to be a package rather than part of the pilosa
package. If stats stops being in pilosa, it still needs
a way to import logger, so logger also has to leave the
pilosa package. Then everything using them needs to import
them and use package selectors on their names.
This doesn't actually add the stats support to roaring,
it just makes it so there's a way to import the stats
code from something in the roaring package.
This commit removes the previous `MaxShard` tracking and replaces
it with an `Available Shards` set tracking. This allows sparse shard
tracking without implicitly tracking all shards in between.
gossip now takes a single "MemberServer" which is implemented by server. Several
interfaces have been removed.
MemberServer contains ReceiveMessage which is a superset of the functionality of
ReceiveEvent, LocalStatus and HandleRemoteStatus are all that's left of
StatusHandler - ClusterStatus was not used and is gone. The Node() method is
actually a subset of LocalStatus() functionality. Maybe we should break up
localstatus or remove Node... not sure.
Remove BroadcastReceiver test which was a bit silly.
NodeEvent can now be unexported, and is.
since the gossip MemberSet has access to Server, it wasn't really necessary to
pass it a Node object when calling Open on it from Cluster. The end goal is to
have it be removed from Cluster entirely, and have it be Opened externally, and
this is a step toward that.
Exposing Node method on Server doesn't really expose any more than was already
there as the same info can be gotten from LocalStatus with a bit of type
casting. I figured adding the method was a little cleaner, and we could collapse
all the functionality when the dust has settled.
The Cluster.open method has been broken into two parts - one of which happens
earlier (at NewServer time), and the other will eventually just be "waiting to
make sure we've joined the cluster". Right now it's calling Memberset.Open, and
then waiting to make sure the cluster has been joined.
pilosa.Server now implements StatusHandler and EventReceiver and needs only
start a gossip memberset. A gossip member set now takes a server as an argument
explicitly and the maze of handlers and receivers and the starting sequence is
somewhat simplified.
Server now trivially implements EventHandler by passing the call along to its
Cluster object which has the actual implementation. This means that less things
will need to refer to cluster.
