Hello Guix!

These patches merge the beginning of reepca’s work on the Guile
implementation of the build daemon from last year’s GSoC.  It
is based on these commits by reepca:

   a647f6e74 deduplication: new module.
   b418ff86b guix: register-path: return #t on success.
   6b979a819 guix: register-path: do deduplication.
   374281f52 guix: register-path: reset timestamps after registering.
   b6d9b2675 guix: register-path: use new %store-database-directory
   4d945be54 guix: sql.scm: split into generic and store-specific parts.
   70cbb8c81 .dir-locals.el: properly indent sql macros.
   bcacbdfd2 guix: register-path: Honor environment variables.
   654c8a776 guix: register-path: Implement prototype in scheme.

I modified things in several ways:

  • Added configury to detect Guile-SQLite3 and make it an optional

  • Moved all the sqlite3-dependent code to (guix store database) so
    that it can really be optional; in reepca’s branch part of it was
    directly in (guix store).

  • Removed (guix sql).  Most of what it provided is now available in
    guile-sqlite3 proper, so I adjusted (guix store database) to take
    advantage of that.

  • Added tests for (guix store database) and (guix store
    deduplication), which allowed me to fix a couple of bugs.

The next step is to start using this internally in lieu of the
‘guix-register’ command.

At some point, we’ll have to make Guile-SQLite3 a mandatory dependency.
It would be nice if someone would take care of making proper releases of
it.  :-)  Any takers?  Danny?

BTW, kudos to you reepca for the nice code!

  Add (gnu store database).
  Add (guix store deduplication).

  build: Check for Guile-SQLite3.
  database: 'register-path' resets timestamps.
