This commit adds a `Future` scope to the configuration options, and for
the time being includes a single flag within that scope: `rename`.
Usage:
--future.rename
The value is a boolean available internally at: m.Config.Future.Rename
Attributes are unmaintained and unused.
They have become more of a liability than a benefit.
This change eliminates them from the codebase.
The only user-visible change (assuming that attrs are not used) is that the attrs field will no longer appear in row JSON.
Long story short: Once we create a server and start it, we can't start
it again. We can't close it and restart it, and we can't just start
it without closing it.
Unfortunately, if the server's config needs to change, we have a Problem
here.
This ultimately means that the retry logic for GetListeners can't actually
retry successfully; if we fail on the first attempt, we necessarily fail
on any later attempts also, and if we try to fix that, we get panics.
But!
We don't actually NEED to retry. We just need to ensure that we can
open a :0 port, extract the actual port number, and use that in places
where the port number mattered, without having to rebind it.
The only actual place we needed to rebind things was opening gRPC
servers, so we introduce a gRPC Listener that can be used instead of
trying to bind to a specified port.
In a bunch of other cases where we had similar logic to try to allocate
and then use a port, we can switch to just using a provided listener.
For instance, net/http has `Serve(net.Listener, handler)`, not just
ListenAndServe(addr, handler).
This should eliminate the weird CI failures from eaddrinuse.
NOT fixed: server/cluster_test.go/TestClusterResize_AddNode isn't working
right now. The new node isn't actually being added to the existing cluster.
I attempted this but was outsmarted by it, and I think fixing the
rest of this is worth it as a separate thing.
port mapper gives out ports from 63000-65000 for the tests
fix another race
http test uses port.MustGetPort

ocd happy
test fix for grpc listener address already in use
test/disco allocates BindGRPC port from the port mapper
dump stack on each GetPort
verify each port is usable right away
server/config.go has Config.Validate() now

quiet, don't dump stack on each port alloc

happy linter
even gossip fallback should not be zero but rather use the port mapper
moved lonquerytime from cluster into server and moved cluster.longquerytime into top level config
kept cluster.longquerytime for backwards compatibility, favored if both longquerytime options are present
- all tests green on RoaringTx
- RoaringTx on by default
- blueGreenTx testing framework available for A-vs-B comparison
of Tx implementations
- flag -tx added to server command line but not wired to
change NewIndex() selection yet.
- 918 green tests, 14 tests red on BadgerTx.
A full list of the 14 red tests on BadgerTx follows.
Note that these red tests represent not defects in BadgerDB
or BadgerTx but rather failures of the pre-existing pilosa infrastructure to yet
be fully adapted from files to using a transactional storage engine.
As such these are tests that RBF should not be expected to
pass yet either.
Fixing the pilosa infrastructure to allow these tests
to go green under Badger is the next and highest priority
order of business, but RBF can get much testing benefit
from the 918 green tests we do have, and hence we merge
as much as we have today.
The 14 red tests when NewIndex() is set to use
BadgerTx are as follows. Note in particular
that pilosa cluster resizing is not working yet under a
transactional store.

support most field types in Inspect() query
currently, there's no support for `time` fields.
those will be dependent upon the output format
and the ability to materialize the timestamp from
the time views.
this commit also changes the response type of the
`Inspect()` query to be a tabular `RowResponse`.
