disco/etcd work: fix lots of races, start all cluster nodes at once.
port mapper gives out ports from 63000-65000 for the tests

fix another race

http test uses port.MustGetPort

rbf: remove :0 port request

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

panic if gossip port is 0. validate server.Config

fix another gossip port 0

builds

quiet, don't dump stack on each port alloc

builds

happy linter

even gossip fallback should not be zero but rather use the port mapper

for datasets with lots of views, because we don't
replicate path, index, field, view strings so often.

implement TopK on time
This replaces the former TopK BSI building algorithm, as the row cache was too expensive.
Additionally, BSI addition has been optimized with specialized adders inside of roaring.

0175c66756 Use immutable.SortedMap for root records
This commit fixes a bug where the root record cache was being
updated in-place causing a race condition with other transactions
using it. The cache implementation has been changed from `rbtree`
to an `immutable.SortedMap`.

8095455355 container performance benchmarking
This adds a series of archetypal containers that represent the
common use cases (arrays, bitmaps, or runs of various cardinalities)
and runs the basic operations against them for benchmarking purposes.

`benchpretty` is an app to snatch the BenchmarkCt* lines from
benchmark runs and display them in a possibly more usable form,
mostly as a precursor to cool analysis things.

This also adds a test to verify that intersectionCount(a, b)
is the same as intersect(a, b).N() for all the archetypal
containers.

This also includes a performance fix for intersectBitmapRun which
was spotted while running these tests.

76fe49d390 un-disable checkptr by fixing the memory problems
Step one: switch to etcd.io's bbolt fork of boltdb.

The etcd-io fork of boltdb isn't archived, and has fixes for boltdb's
interactions with checkptr, allowing us to drop the checkptr-disabling
hackery.

This seems to be a drop-in replacement; etcd/bbolt says that the file
format is "fixed" (I believe in the sense of "unchanging"), and I can
run pilosa on an existing data directory with this.

Step two:

Fix missing caps in roaring.go that were also triggering the same
issues.

31d54010f8 blue_green verification and migration capabilities.
- on startup in blue_green mode, we will migrate
   blue to green if blue is empty.
 - otherwise, when blue has data, we verify
   against green before proceeding with the
   blue_green run.
 - small optimization in the rbf cursorx.go to
   short-circuit processing on a nil bitmap.
   This avoids a roaringparanoia tag panic.
 - back out holdbkg.go, was too slow.
   add a distinct Holder.imu lock instead.

2eb097c14d blue_green migration. holdbkg.go holder goroutine.
- 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.

150c8a5b06 database per shard, HolderConfig, rbf bit-wise import speedups.
- introduce Query Context (Qcx) for managing database-per-shard.
- replaces the MultiTx, so mtx.go is retired and removed.
- introduces the HolderConfig struct and all Holders now have
  a path from birth.
- rbf speedups on bitwise writes
- badgerdb is removed due to unresolvable write conflicts.

cecaf99ee4 testhook: leak auditing infrastructure
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.

123ce41840 add lmdb, Tx call stats, and prep for db/shard.
- lmdb as a backend (lmdb.go)
   (lmdb is the fastest known transactional storage backend)
 - per Tx call statics report enabled with PILOSA_CALLSTAT=true (stattx.go)
 - framework for per-shard db (dbshard.go)
 - txfactory handles any pair under blue-green testing (txfactory.go)
 - enable CGO in Dockerfiles for lmdb

547ee14f5b all test green on rbf. WOOT.
- rbf had races around the new rootRecords cache in tx
 - rbf tx needed a write lock on the db now that rootRecords are written
 - added a global registry for rbfDB to correctly dedup instances
 - implement DeleteFragment, DeleteIndex for rbf
 - use badger style keys for rbf to allow content checksumming to be list
    containers in the same order
 - lots of other integration of rbf into pilosa layer.

97b530ca78 integration of Tx, RoaringTx and BadgerTx implementations.
- 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.

This allows a BSI field to have an option indicating
that it is a foreign key to another index. If the foreign
index has column keys, then this field handles string values

`All()` is a PQL function that can be used as a typical
