A configurable limit has been added to restrict the number of
mutating calls in a `pql.Query`. This is to prevents requests from
timing out from large queries.
The default is set to 5000 writes per request and is configurable
through the configuration file and the command line flags.
This mainly involved running `RecalculateCache()` on all fragments
in `TopN` tests. It seems these tests have been running as LRU
caches, and once we made `ranked` the default, they stopped working.
Some tests were affected by the change in partition number and
therefore the change in fragment to node mapping.
Changes Gossiper to NodeSet.
Adds StaticNodeSet (for testing) and GossipNodeSet (for memberlist) implementations.
Changes NodeSet interface to return a pilosa-specific generic instead of `NodeSet interface`.
Removes NumMembers from interface (which is specific to memberlist).
Implements a Messenger interface with which to send inter-node messages via NodeSet.
The Pilosa implementation occurs in the GossipNodeSet.
Implements the Messenger as an object on Server, Handler, and Index.
Uses HealthStatus constants.
Removes commented-out code.
for gossip, make sure to bind to both host and port, and advertise those as well
adjust messenger to work with the db schema logic
add dependencies: hashicorp/memberlist, golang.org/x/sync
add dependency: golang.org/x/net
Uses `errgroup` to handle errors from broadcast messages.
Marshals message one time instead of once for every node.
Adds error handling for some errors that were being swallowed.
this affects the scanner/parser and makes it produce signed ints rather than
uints, and so it affects all code that is expecting unsighed ints to come out of
the parser.
This commit changes the executor to select a bitmap from the
standard view or the inverse view based on whether the row label
or column label is specified.
