If non-primary host fails to process a request, retry on primary node.
conditions when we should not do this:
- no error
- we've aleady tried the primary
- we're making a status request to get the primary node...this
could lead to lock contention if we allow it to happen as we are
making an http request within an on going http request to discover
the primary node.
This also deletes the RemoveHost method and the associated test b/c
it is not used anywhere anymore and updates the returned error type.
We have code to correctly fill in cell.BitN when a leaf cell already
exists but isn't of the correct sort, but not to handle the case where
it already exists and *is* a BitmapPtr, but doesn't necessarily have
the right BitN value.
This test tries to verify that we can create multiple fields on a cluster
without deadlocking or getting errors *other than* ErrFieldExists or
wrappers of it. The "or wrappers of it" implies a change to ConflictError's
semantics, but honestly I think it should have had those semantics all along.
Two CreateField messages reaching different nodes in a cluster at the same
time could cause a deadlock because each CreateField runs with a write lock
held, then issues requests to other nodes which, at a minimum, need
a read lock and which may require a write lock. Reorder things a bit to
make the broadcast to other nodes happen outside the lock. We may also
need to do something to have nodes handle the case where something's been
created in etcd but they haven't gotten the message about it yet.
Creates a timestamp field in the TestSQLQuery dataset.
Modifies a helper function to allow datasets with
timestamp to be properly converted to table responses.
Adds test cases for:
- conditional where clauses
- where clause with group by
- timestamp within where clause
- select distinct with where clause
This was in response to some feedback we got about the new release
format. Executables were no longer had executable permission due to
going through S3 (hence the tarballs), and we wanted a more consistent
directory structure in the final release which included the versions
of various components.
this is related to work for [fb-1127](https://molecula.atlassian.net/browse/FB-1127)
cardinality reporting has caused no shortage of issues such that we recommend
disabling them almost everywhere.
this commit removes the cardinality calculation for right now, as well as the option
to enable/disable schema details.
