This commit does several things, the big change is to try and construct a
simpler query for SQLite. I'm not confident that SQLite's query planner can
look past handling the NULL parameters, so I think it could be helpful to try
and create a simpler query, both to avoid that problem if it exists, but also
move the complexity in to Guile code, which I think is a bit more manageable.
The way ordering is handled is also changed. Order is one of the filters,
although it's not a filter, and some of the other filters also influenced the
order. I think there are things still to fix/improve with the handling of
ordering, but at least this commit just has the ordering happen once in the
query.
* src/cuirass/database.scm (filters->order): Remove procedure, inline in to
db-get-builds.
(db-get-builds): Change query generation in an attempt to make it easier to
tune the queries for performance.
Add a "optimize" step that occurs when starting up the main Curiass
process. Currently this does two things, but could be extended to do more.
The "PRAGMA optimize;" command prompts SQLite to ANALYZE tables where that
might help. The "PRAGMA wal_checkpoint(TRUNCATE);" command has SQLite process
any unprocessed changes from the WAL file, then truncate it to 0 bytes. I've
got no data to suggest this helps with performance, but I'm hoping that going
from a large WAL file to a small one occasionally might be useful.
* src/cuirass/database.scm (db-optimize): New procedure.
* bin/cuirass.in (main): Run it.
* src/cuirass/database.scm (db-get-inputs, db-get-checkouts): Export.
* src/cuirass/http.scm (evaluation-html-page): Pass #:checkouts and
#:inputs to 'evaluation-build-table'.
* src/cuirass/templates.scm (evaluation-build-table): Add #:checkouts
and #:inputs. Emit a table with "Input" and "Commit" columns.
The number of threads is copied from bin/cuirass.in. When you have at least
two processors, this will allow database queries to be executed in parallel.
With some crude testing using the Apache HTTP server benchmarking tool (ab
from the httpd package), the max request latency does seem to drop when
multiple threads are used, especially when the database queries are slow (I
tested by adding usleep to the worker thread code).
* src/cuirass/database.scm (with-database): Pass #:parallelism to
make-worker-thread-channel.
While this is a generic method, and initializer function will give the
flexibility required to create multiple worker threads for performing SQLite
queries, each with it's own database connection (as a result of calling the
initializer once for each thread). Without this change, they'd all have to use
the same connection, which would not work.
* src/cuirass/utils.scm (make-worker-thread-channel): Change procedure to take
an initializer, rather than arguments directly.
* src/cuirass/database.scm (with-database): Adjust to call
make-worker-thread-channel with an initializer.
* tests/database.scm (db-init): Change to use make-worker-thread-channel
initializer.
* tests/http.scm (db-init): Change to use make-worker-thread-channel
initializer.
As far as I'm aware, it's necessary to use a separate thread for interacting
with SQLite as one of the threads used for fibers will be blocked while the
SQLite query is running.
This doesn't mean all queries have to be executed one at a time though,
providing the queries are executed outside the threads used by fibers, and a
single connection isn't used in multiple threads.
These changes start to move in this direction, first by just changing the
terminology.
* src/cuirass/base.scm (clear-build-queue, cancel-old-builds): Change
with-db-critical-section to with-db-worker-thread.

The internal rowid's are used for builds as you can request builds by using
the rowid in the URL.
The motivation here is to enable running VACUUM operations in SQLite, without
risking the rowid's for Builds changing. It would be bad if they change, as
they're used in the URL's for builds.
* src/schema.sql (Builds): Add id column.

UNIQUE constraint.

Being able to take a derivation and query the build information is useful, but
in cases where there are multiple derivations that produce the same outputs,
the probability of getting the data back from Cuirass is reduced.
This is because Cuirass might not have build the exact derivation you have,
but a different derivation that produces the same outputs (this can commonly
happen when a related fixed output derivation changes).
Cuirass doesn't store derivations if they produce the same outputs as a
derivation it already knows about, so it can't determine if this is the
case. Therefore, provide a way of querying build results by output, rather
than derivation.
The motivation behind this is to make it easier to import build information in
to the Guix Data Service.
