Christopher Baines 9265949cf6 cuirass: Perform some database "optimization" at startup.
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.

* bin/cuirass.in (main): Run it.

README

Cuirass is a continuous integration tool using GNU Guix.  It is intended as a
replacement for Hydra.

Requirements
============

Cuirass currently depends on the following packages:

  - GNU Guile 3.0.x or 2.2.x
  - GNU Guix (and all its development dependencies)
  - GNU Make
  - Guile-JSON 3.x
  - Guile-SQLite3
  - Guile-Git
  - Fibers

A convenient way to install those dependencies is to install Guix and execute
the following command:

   $ guix environment -l build-aux/guix.scm

This will build and enter an environment which provides all the necessary
dependencies.

Build Instructions
==================

When all the dependencies are available on you system, in order to build and
install Cuirass, you can proceed with the usual:

   $ ./configure && sudo make install

An alternative way is to directly install Cuirass in your Guix profile, using:

   $ guix package -f build-aux/guix.scm

To build it, but not install it, run:

   $ guix build -f build-aux/guix.scm

Example
=======

A quick way to manually test Cuirass is to execute:

  ./pre-inst-env cuirass --specifications=examples/hello-singleton.scm --database=test.db

This will read the file "examples/hello-singleton.scm" which contains a list of
specifications and add them to the database "test.db" which is created if it
doesn't already exist.

'cuirass' then loops evaluating/building the specs.  The database keeps track
of the specifications in order to allow users to accumulate specifications.
To resume the evaluation/build process you can execute the same command
without the '--specifications' option:

  ./pre-inst-env cuirass --database=test.db

To start the web interface run:

  ./pre-inst-env cuirass --web
