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.
We want to distinguish different *kinds* of GroupCounts, so we're
making the GroupCounts parent object track its type so we can keep that
correct.
Adding this to protobuf, etc, then creates some weird behaviors
because sometimes we expect []GroupCount, and sometimes we expect
*GroupCounts. This implies changes to test cases. Also, the
changes to test cases imply that some test cases are probably now
wrong; for instance, they're expecting a "sum" column, equal to zero,
when no sum was requested.
We try to make the encoder handle a []*GroupCount gotten from another
node without panicing, and avoid breaking the semantics of the existing
messages, renumbering messages or components, etc.
Since a previous version, the `.Groups` member has been privatized,
and the `.Get()` convenience accessor has been renamed `.Groups()`
and is now used consistently in a way that should reduce the risk
of nil pointers causing crashes. Also, NewGroupCounts is used in
a couple more places.
This adds a "duration" parameter to RowResponse and TableResponse, which
will be populated with the query duration in nanoseconds.
For QueryPQLUnary and QuerySQLUnary, the duration is a included in the
returned TableResponse.
For QuerySQL and QueryPQL, only the first RowResponse in the stream will
contain the duration.
- 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.
fixes#703#676
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.
