When unmarshalling ops, we weren't adding a meaningful OpN to them,
resulting in misleading reports from `pilosa inspect`. Also, we were
mistakenly reporting things as "mapped" when they were actually
using their internal storage (as with small array containers).
Add the "sanity check" to `pilosa inspect` so that errors like the
above get noticed more easily and corrected. Also, to make that work,
have roaring.InspectBinary actually put containers in the bitmap
it creates rather than just creating info entries for them.
In nearly all cases, we can just switch ioutil.TempDir->testhook.TempDir
and similarly for TempFile. There's one case where we can't because we
need files to be removed before tests are over.
Also in the process give identifiable names to a lot of temporary files
and make sure they're being cleaned up, and don't use "/tmp/foo" as a
file name in a test that could be running in more than one test process
at once. :)
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
- fix a bug in computing leafCell.BitN in a run after a bit Remove
- shrink bitmaps on remove
- util_test.go has Cursor.DebugSlowCheckAllPages to verify;
used by cursor_test.go
- 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.

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.
1. Tests can choose the Tx engine desired by setting the PILOSA_TXSRC
env variable. For example:
PILOSA_TXSRC=badger go test -v -run TestImportClearRestart
2. pilosa server --tx is enabled now.
Examples:
pilosa server --tx roaring # gives the legacy approach.
pilosa server --tx rbf # will activate RBF
pilosa server --tx badger # will activate BadgerDB
pilosa server --tx badger_rbf # will run Blue-Green badger to RBF comparisons.
and so forth. See pilosa server -h or txfactory.go for all valid --tx choices.
3. Mechanism that makes both tests(1) and pilosa server(2) work at once:
pilosa/server/server.go injects PILOSA_TXSRC into env to
communicate with NewIndex in pilosa/index.go.
- 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.
