DAX now relies on Postgres, so we use the Postgres which is already in
the IDK tests (for the external lookups thing) to use as the
controller's metadata store as well. The env variables are a little
confused, but I'll clean that up separately.
There's no actual way to forcibly sequence our check of the history
until after the history has been updated, but it's pretty fast usually,
just not always instantaneous. Without this, adding a few millisecond
delay in the tracker reliably produces the test failures we kept seeing
with an unexpectedly low length of 3. With this, it passes consistently
even with the artificial delay.
The query tracker being asynchronous is probably fine, but we need
to test it as though it might take a while.
Switch Serverless from using BoltDB to Postgres as metadata store.
Previously, the controller stored all metadata to BoltDB. This implements SQLDB (currently Postgres flavored) as the backing store for metadata. This will allow us to have multiple instances of the controller running for HA, and to easily inspect and repair the contents of the metadata store.
Unfortunately, it was not straightforward to keep the BoltDB implementation working alongside the SQL one, so it will be removed in a later patch. Once that's done, the SQL implementation should allow for a number of simplifications of the schemar and balancer interfaces.
Database migration is built directly into the application by embedding the migration files and logic from the `soda` command line tool. When connecting to the RDBMS, the app will always attempt to create the necessary database and apply any outstanding migrations.
Integration tests truncate all tables upon start, but *not* at the end, so the state of the database can be inspected after integration tests.
Had to refactor some of the controller's background tasks to make sure they get properly shut down on controller exit.
This is the time being used in our other CI pipeline.
The alternative to doing this is ripping out all of this code so that
we're not running two CI pipelines...
* renamed 2 system tables
* adding table column for types
* added a type field to fb_database_nodes system table
* updated ClusterNode struct
* adding backwards compatibility
this commit also adds support for ordering systemTables and implements the method
* fixed linting

Co-authored-by: Travis Turner <travis@molecula.com>
* Enable linter: stylecheck
This enabled the stylecheck linter, but excludes some staticchecks for
now. The following are ignored because they will take a bit of time to
address, but the intention is to address them and remove them from the
exclusion list.
ST1000: at least one file in a package should have a package comment
ST1003: golang naming standards
ST1008: error should be returned as the last argument
ST1016: methods on the same type should have the same receiver name
ST1020: comment on exported function
* Address ST1015
For some reason this failed in CI but not locally. I can't figure out
why that check isn't happening locally. This just moves the switch
statements around so that the `default` is the first (or last) item.
* Adjust error string in test to match case-adjusted error
* Remove TestCloseTimeout
* stub out a test framework for fbsql
* Introduce fbsql integration test framework.
This also adds support for `pset location` to set the geo location (i.e.
time zone) in which timestamps should be displayed. And it adds support
for comments (lines starting with `--`) in the line reader/splitter.
* Replace Stdin and Stderr with setters and un-export them
* Add (commented out) linters that we should introduce
I went through the available linters and added (commented out) the ones
I think we should work on in the near term. In other words, fix them,
then uncomment them so they are enabled in CI.
* linter: errchkjson
* linter: ineffassign
* linter: gosimple
* linter: errname
FB-1897
The specs for the datetimepart function are, as far as i can tell,
identical to the existing datepart function. Per Pat, replaced the
datepart function with datetimepart rather than just adding
datetimepart as an alias. Made sure existing tests that were using
datepart got switched over.
Second go at this after sorting out weirdness with git.
Until we have API token support, connecting to cloud requires the
cognito configuration. This commit adds the production cognito settings
for defaults, and we have intentinally omitted these from the documentation.
FB-1896
Added the datetimename function, which returns parts of a timestamp
as strings. Month and day of the week are named ("January", "Monday")
while others are returned as a string of digits ("2023").
Added tests to the test definitions.
* Set fbsql prompt based on the connected database
This also changes the prompt to align with psql, where it begins with:
db=#
and the mid looks like:
db-#
* Require organizationID in on-prem, serverless queries
* Support meta-commands in `--file` command
I'm not sure why this was restricted before. Just an oversight.
* Change default history file name to fbsql_history
* Add port short flag: p
* Support meta command \list (for \l) and \out (for \o)
* cleanup while writing docs
* Have \cd with no arguments change to home directory
* Avoid shadowing `action`
* Add kafka support to CLI (fbsql)
This commit adds the ability to provide a `--kafka-config` command line
argument referncing a toml file to configure kafka.
* Move "Molecula Consumer" message to the logger; hide it in basic mode
* Fold decimal(scale) into kafka.source-type
* Build fbsql with cgo in docker for CI
* Re-organize the fbsql kafka config and setup.
Allow field config to use the table schema if no fields provided.
* Display timestamp fields with format RFC3339Nano
* remove kafkaRunner (no longer used)
* Fix cli/batch test (and make sure it's not excluded from CI)
The logic in our Makefile was exluding from tests any package with
`/batch` in the package name. This excluded `/cli/batch`, which is not
good.
This commit changes the exclusion logic to include the `/v3` portion of
the package name, so `/v3/batch`.
* Rename Basic() to SetBasic()
Buckle in, this one's a ride.
This is attached to the same PR as a fix for exiting abruptly
during some tests because I ran into that issue, and comprehended
it, while trying to track down weird and sporadic test failures
that were actually this issue.
The actual, underlying, problem: `make test`, by running all the
tests at once, was hitting a bug that was mostly effectively
triggered by running the `dax/test/dax` tests, and the top-level
`featurebase/v3` tests, at the same time. However, the interaction
was nothing as obvious as temporary files, etcd configuration,
or whatever.
We were running out of port numbers.
The tests were using a bit over 30k simultaneous established TCP
connections, each to different ports, because we were creating
new clients for basically every single operation. For instance,
in a single SQL test that did an import and then a read, we
were creating a new client for each field written to, and then
also creating a new client for each field in results that needed
key translation. And none of these clients were closed or
timed out in any way. In fact, Go doesn't really *do* "closing"
of clients; the closest is that an http.Client can be told to
close idle connections that it has been keeping open.
The worst offenders were both named `fbClient`, and were nigh-identical,
except one of them was implemented as a method on `importer` in the
IDK tree, and one was a standalone function.
It may seem surprising that the method on `importer` is using a shared
client pool for all importers, rather than a new pool for each
importer. This is because we potentially make quite a few importers
during tests.
Before this, running either of the dax tests or the top-level
tests would show well over ten thousand simultaneous ESTABLISHED
connections. After this, the dax tests used nearly twenty.
The problem with port consumption like this, while more noticeable
on MacOS, is also something we could hit on the CI runners, especially
if a single runner ended up with more than one test suite running
at the same time. This probably manifests as sporadic very strange
failures of CI, with messages about "cannot assign requested address".
(Note that an outgoing connection to a successfully-created port
requires *another* port to be assigned for the outbound socket.)
This was complicated dramatically by the fact that, for some
utterly cursed reason, it was *especially* common for the point
at which we hit this, in the top-level featurebase tests, to be
running one of the backup tests in TestVariousQueries, and
specifically, to be hitting it on the dataframe part of the
backup... Which is to say, on the *one* path in the backup function
that called log.Fatal, and thus terminated the featurebase process
abruptly without further commentary.
The testing package is full of subtle magic, and one of the most
subtle is this: t.Logf, etcetera, all write to a buffer which is
then displayed after the test is run. Which means that, if you
exit, the buffer is never displayed. This means that, if a test
case can fail in a way that causes an instant exit, you don't
hit defers, you don't get your log messages, you just get a mysterious
exit of the process.
We have two cases where backup commands were calling log.Fatal
instead of returning an error. The error in question is displayed
correctly and informatively if returned, so we return it.
We also have one case where we were using os.Exit to avoid a
deadlock. Instead, we make the thing that would deadlock
conditional on the test not having failed. In the event that
the test fails, we now print our failure message correctly,
then also report an unclosed cluster. That's fine.
