aggregate{Avg,Min,Max}->Update now tested for DataTypeDecimal.
{avg,min,max}PlanExpression->WithChildren now tested.
percentilePlanExpression->{Evaluate,Plan,WithChildren} is not
tested because percentile gets sent directly to PQL rather than
getting planned and evaluated in SQL.
aggregateLast->everything is not tested because Last is not yet
completely implemented.
We distinguish between "TrackExistence option is set"
and "we are actually doing existence tracking", to avoid
mishaps like accidentally creating an "existence" view for
a BSI field or something like that. This logic was being
done probably-correctly in one place, and ignored or
handwaved in some, so this is an attempt to just make
it more consistent.
We had two different versions of this, and a comment referring to a third
which doesn't exist, so I've consolidated them and made them slightly
pickier, to avoid problems like the one I ran into developing the existence
tracking where one of these optimistically transformed names it actually
shouldn't have. Now if we don't expect a view name, we yield an error,
rather than silently performing a transformation.
This also implies updating the ImportRoaring_MultiView test to use
two valid view names.
There's a lot going on here. First, we were treating "the test is
a Condition" as implying BSI, which it doesn't anymore. Second, the
behavior of conditions was weird and BSI-specific. Third, we had
to propagate these changes and features throughout a bunch of code,
including both the core featurebase code and the DAX replacements/copies
of it, plus the SQL3 layer.
We refactor this so that tests for equality and inequality work for
non-BSI fields, so now if you accidentally use `==` in a Row call
on a non-BSI field, it still works; that's not specific to BSI
fields anymore.
We add a TrackExistence flag to fields, and propagate it through
things like our protobuf code, etcetera, so that we can successfully
create fields. Newly-created fields get this by default, because
we add it unconditionally to them, but the paths that are being
called with existing fields don't add it. So, when we "create"
(really, just load the definition of) a field from something stored
in the schema, we don't add TrackExistence to it, but any path to
creating a new field should.
A time quantum field with NoStandardView will *effectively*
lack TrackExistence.
For sets, mutexes, and time quantums with a standard view, anything
that sets bits will also set a corresponding bit for the record in
a new "existence" view. This allows us to distinguish between an
empty set and a null, and also allows null checks to be constant-time.
When clearing bits, we don't clear existence bits EXCEPT that if
you clear a bit in a mutex, *and the bit actually existed*, we clear
the existence bit. For sets and time quantums, clearing bits never
clears the existence bit.
Deleting records clears the existence bit.
We also add code to the `batch` subpackage to generate suitable
existence field bitmaps and import them. This logic correctly handles
empty sets and nils. The `batch` package does not allow specification
of anything equivalent to clearing a single bit from an existing
record, so we don't have to deal with the mutex complexity in that
case, which is good because it would be impossible.
This requires a number of other subtle changes, such as allowing
new fields to have more than one FieldOption specified for them.
We also drop the handful of implementation bits relating to the
"fullySorted" internal-use-only import flag, which existed only to
support the JSON ingest API, which we've removed.
The most dangerous part of this is that the mutex semantics are
impossible to implement on top of our existing API, because they
require us to know, not how *many* bits we cleared, but which
*specific* bits we cleared. I've implemented this as a new Tx method,
which is almost certainly going to be tech debt one day; if we some
day drop the Import API, we should remove that.
The testing for this is only currently covering the Set/Clear
behavior of PQL, and the Import API. The batch tests haven't been
written yet.
Fields that don't have existence tracking enabled refuse to perform
null/not-null tests. They should also report themselves as having
no null values -- if a record exists, sets in it are considered
empty rather than null.
The SQL3 support requires a number of subtle modifications to both
featurebase and some addon tooling. The essential thing is dropping
the unconditional translation of nil slices to non-nil empty slices
in translateResult, both in the executor and the orchestrator. We
also modify the logic that handles generating results from Extract
calls, to ensure that non-null sets get an empty slice created for
them even if they never have any values assigned.
The expected results for some tests are different now; we expect to
get nil slices, rather than 0-length non-nil slices, for fields which
were never written for a given record. Most tests were not changed.
(In every case, if a test was failing, I actually checked the logic
before changing expected results. This required a lot of tracking down
of edge cases.)
The batch package now rejects as an error attempts to clear single
bits from mutex fields, because so far as I can tell it's simply
impossible to have a roaring import that specifies the correct semantics
there; you can't tell whether to clear an existence bit without
access to the currently-set bits, which the batch API doesn't have.
We already supported the special case of specifying a clear value
of nil for clearing a mutex field; now that is the only allowed
value for a mutex field to have in row.Clears.
We change the logic for fixing up incoming view names (in two places)
to stop assuming that any view in a time field other than "" that does
not have viewStandard as a prefix is a partial time quantum name that
should have "standard_" prepended to it. This allows us to submit
bitmaps for "existence" to time quantum fields and not have them
silently transformed into "standard_existence" because that's what we'd
do with "202203".
We drop the field ClearBits method, which was totally unused.
We drop the sliceDifference function, which was used in a previous
mutex implementation and hasn't been used in ages, and the test
case for it, and the helper function used only by that test case.
At some point in some other refactor, this option got removed from the
function call it was supposed to be an option to.
But actually that was... not correct either.
Because if you look closely, it turns out that this test was completely
broken; we were ignoring the results that were in the test, and using
inline results, but that's okay, because we were also doing the wrong
query for the second test, and ignoring the Field Options specified in
the test... all fixed now.

FB-2041
Added tests for typeIsTimeQuantum and typeIsSet and made them pass.
Added tests for DataTypeTuple cases in typesAreAssignmentCompatible.
Timestamp conversion checking is handled before it gets to that
point but I left those branches in as a backstop.
Checking to see if DataType[String,ID]SetQuantum can be assigned
to themselves doesn't appear to be reachable currently but left
those branches in, because something may use them in future.
Added one test to the DAX skip list since it's the IDSetQ version
of a StringSetQ test that was already on there, changed skip list
to refer to both tests by name instead of by number.
* serverless sqldb use same env for test config as normal
* rip boltdb implementation of controller backend out
it was replaced by postgres and no longer works properly.
This involved migrating a number of tests which only worked with
boltdb, which exposed several ways in which the postgres
implementation had slightly different behavior from the bolt
one:
1. ordering of results in some cases, and
2. (more importantly) erroring when a record to delete was not
found. The bolt implementation silently ignored it when things to
delete weren't found, so we make some changes to match that behavior.
Also stopped propagating CreatedAt and UpdatedAt from DB tables into
dax types. These were breaking existing tests. Perhaps it would be
better to actually use them, but for now they will only exist at the
DB level.
This change set also moves the insertion of the directive_versions
record out of migrations and into the startup/connection code. Having
this in the migrations was a bit ugly because you couldn't just
truncate all the tables and have everything work from
scratch. Inserting it during startup is fairly innocuous, and will
just continue on if it already exists.
* update directive_version test
I changed the initial value to 0 so that the first version that gets
sent out is 1
* fbsql disconnect from database with `\c -`
This adds the ability to disconnect from the current database by passing
a hyphen to the `\c` meta-command.
* Update cli/cli.go

For on-prem serverless, if we restart the process containing the
controller and computer(s), when they come back up, the controller
doesn't know that the computers have been restarted, so it doesn't send
them a directive. This change forces the controller to send a directive
upon startup by a computer.
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

* 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

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()
