- check that serverlessStorage is not nil before closing it
- check that we don't already hold a lock on a serverless storage
Manager before trying to load it. This fixed at least one test failure.
These jobs all need TLC and to be moved to the new ansible platform. For
now, we're removing them because if they accidentally get triggered,
they cost a lot of money very quickly, and don't necessarily get us
anything useful if they pass or fail.
Revert "Updating any AWS shape instance to use"
...our existing reserved instance types. This simply ensures if we ever
do run one of these tests it is against existing reserved instances. If
the tests get removed thats OK also."
This reverts commit 69be968d6d.
* Prevent file corruption when writing tar backup to stdout
FB-1794
Tar backups written to stdout were coming out corrupt. This turned
out to be due to log messages getting written to stdout and ending
up in the tar file. We now check to see if the tar file and the log
are both going to stdout, and if they are, send the logs to stderr
instead.
Testing did not have any kind of consistency or validity check. We
now compare a tar file sent to a file and a tar file sent to stdout
to make sure they're the same. This does not guarantee correctness
but does at least catch this form of corruption.

* Make interfaces more specific than "MDS"
- Introduce `dax.Schemar` interface
- Introduce `dax.Noder` interface
- The rest is generally to standardize on the new interfaces.
- Remove `pilosa.SchemaInfoAPI` interface
- Move `TranslateNode` and `ComputeNode` types from controller to dax package
- Remove `queryer.FeatureBaseImporter`
- Remove `queryer.MDS` interface
- Remove `queryer.Importer` interface
- Identify types using an "MDS" interface and split into Noder/Schemar as necessary
- Changed `Queryer.orchestrator` to a `map[qual]*qualifiedOrchestrator` because we can't share an orchestrator across quals
* Convert orchestrator to use TableKeyer
* Fix "qualifer" misspellings
* Remove `track_existence` and `shard_width` from SHOW TABLES output
* Thread Owner, UpdatedAt, UpdatedBy through SchemaAPI
I took the liberty of renaming "LastUpdatedUser" to "UpdateBy" to align
with "UpdatedAt".
This commit introduces an interface called `TableKeyer` which anything that means to represent a "table"
can implement. Examples are `dax.QualifiedTable`, `dax.Table`, and `string` (for legacy pilosa calls
where Execute simply took `index string`).
In the case of `orchestrator.Execute()` and `qualifiedOrchestrator.Execute()`, we are intentionally strict
about which type of `TableKeyer` the respective method accepts. If we find, in the future, this is too
restrictive, we can loosen that; but for now it helps us understand what is expected.
* Move batch.Importer interface to pilosa.Importer
In addition to moving the interface, it updates all the methods to use
dax.TableID (for example) intead of a string pilosa index name.
* Change unused onPremImporter methods to no-op.
onPremImporter is a wrapper around API which implements the Importer
interface. This is currently only used by sql3 running locally in standard
(i.e not "serverless") mode. Because sql3 always sets
`useShardTransactionalEndpoint = true`, There are several methods which this
implemtation of the Importer interface does not use, and therefore they
intentionally no-op.
* This adds in support to the lattice UI application to use the SQL3
endpoint. If the `/sql` endpoint returns 404, it will use the SQL1
endpoint. If the `/sql` endpoint is available, it will send SQL queries
to that. It does not try the SQL1 endpoint if the SQL3 endpoint returns
an error processing the query. That is, it is all SQL3 or SQL1.
- Below are the specific changes:
- Adds a file that contains functions for interacting with http services as opposed to just grpc/event-based services. As of this commit, it is only the SQL3 endpoint.
- This adds a variable to track if we are using the SQL3 endpoint or not
- This adds a function to handle the response from the SQL3 endpoint
- Adds a function to eventServices to query the sql3 HTTP endpoint
- Fixed a missing semicolon in grpcServices

* Introduce ServiceManager and Refactor DAX Integration tests
The ServiceManager provides an interface with which to manage
featurebase (dax) services (mds, queryer, computer). It replaces the
confusing interface implementations in /dax/server/server.go (which
optionally used pointers to in-process objects to satisfy an interface)
with (for now) http implementations. The thought is that even if we're
running all services in-process, we should communicate between services
over http in order to mirror what we would do in a production
environment where the services are running on different nodes.
This batch of commits does quit a lot, most of which is captured here:
- Added `path` support to `dax.Address`. Address is now a string of the form [scheme]://[host]:[port]/[path].
- Added `Holder.directiveApplied` to determine (in tests) if the computer has completed applying the latest directive. This is somewhat temporary until we improve the mds-to-computer logic.
- Removed the "service prefix" code which was prepending client URL paths with the prefix. Instead, the serviceType (mds, queryer, computer[n] is now part of `dax.Address`).
- Removed, from the dax config, the top level `StorageMethod` and `StorageDSN` and now just have `MDS.Config.DataDir`.
- Added `Computer.Config.N` to specify the number of computers to run in-process.
- Moved the `pilosa.MDS` interface to `computer.Registrar`. This is an example of getting the interfaces defined in the right packages.
- Added `SnapshotTable()` method to the mds client (to align with its API).
- Changed `Balancer.AddJob()` to `Balancer.AddJobs()` to support, for example, adding 256 partitions in a single call. Refactored some of the naive Balancer to account for this.
- Added a `Seed` to the top-level config. It's not really useful because of package `crypto/rand`.
- Added an in-memory implementation of the DisCo interface and disabled etcd in a computer service.
- Create sepearte data-dirs for each in-process computer.
- Disabled grpc in dax.
- Modified the sql3 test definition format to support multiple insert steps and separate query results (to align with those steps).
* Changes necessary to get multiple computer instance running in-process
For now the config looks like this:
```
[computer]
run = true
n = 4
```
but we can probably just change that to be something like:
```
[computer]
run = 4
```
*Issues found running multiple "computers" in-process*
- grpc was trying to bind on the same port
- changed GRPCListener from `*net.TCPListener` to `net.Listener`
- created a nopListener and set to that for now (i.e. disabled grpc)
- etcd was starting more than once
- changed dax to use in-memory implementations of the disco interfaces (i.e. stop using etcd)
- IDAllocator (which uses boltdb) was trying to open the `idalloc.db` file more than once
- realized we have to set separate data-dirs for each holder. that fixed it.
* Port dax integration tests to ManagedCommand
* Modify Balancer-related methods like AddJob to AddJobs
There were (and still are) a lot of places where we were adding on job
at a time, even when we had a long list of jobs to add. This resulted in
every job add (for example adding 1 of 256 shards) taking ~40ms, or over
10s to create a keyed table. One reason was because each job add was
making multiple boltdb transactions.
* Port over more dax integration test stuff
* Add DirectiveApplied to signify that snapshot/writes have loaded.
We use this in tests to avoid using sleeps.
This should be considered temporary; we're going to need a more robust
solution for determining when a computer node is ready to serve complete
data.
* Finish porting dax integration tests
* Improve godocs
* Remove docker-based DAX integration tests.
* go mod tidy
* Move test/managed.go to avoid package conflicts
* Modify IDK integration tests to work with ServiceManager changes
This is really just computer -> computer0
And the MDS DataDir config change.
* cleanup found during review
* echo $CI_COMMIT_REF_SLUG in CI
* remove docker image arg, use build instead
* fixed a bunch of issues with non-pql aggregation; moved some decimal related functionality; made top actually top (for the non-pql case); experimental create function
* drive up test coverage
implements an fb_exec_requests system table. The purpose of this table is to allow access to internal state to see what queries are running and have been run.

Reproducible builds are something we should be doing, and we are there
as far as making them in CI is concerned with this change.
The changes to the Dockerfile/Makefile do nothing if the
SOURCE_DATE_EPOCH environment variable is not set before `make build`
happens, or if the build arg is not passed in to docker.
FB-1771
In api_test.go, it was being used to make sure that incorrect input
produced the right errors; this is now handled by making sure the
error isn't nil and then checking its string against the expected
error string.
In executor_test.go and internal_client_test.go, it was being used
to compare QueryResponse structures, which contain an error.
handler.go now has a function specifically for comparing them,
which can provide additional detail if necessary.
Added a test for SameAs to handler_test.go.
* tighten up checks for order by expressions fixed ordering by expressions
* added testing to cover order by cases
* Add DecimalAgg member to proto GroupCount definition
In DAX, where we have split the orchestrator from the executor, and the
orchestrator can run on a different host, there are cases where
`GroupCount`s can travel over the wire via the Internal Client. In these
cases, when the group count contains a decimal aggregate, we need to
send that value as the appropriate type.
* fixed missing cases in order by and case block eval
