A couple of months ago, I found myself working on hot fixes for Cuirass, whose repository had been gathering dust for months. One thing leads to another, and I=E2=80=99ve worked on a few improvements recently: =E2=80=A2 Guile-Squee (interface to PostgreSQL) now cooperates with Fiber= s, meaning that =E2=80=98exec-query=E2=80=99 is suspendable. =E2=80=A2 Thanks to advice from Chris Baines, Cuirass now uses a database connection pool instead of the database service thread it used to have. =E2=80=A2 =E2=80=98cuirass remote-server=E2=80=99 and =E2=80=98cuirass re= mote-worker=E2=80=99, the processes in charge of distributing builds remotely and that communicate over ZeroMQ, are now single fiberized processes (this was made possible by making the =E2=80=98receive-message=E2=80=99 procedure, built upon Guile-Simple-ZMQ, cooperative). These commands used to spawn a bunch of processes and threads. =E2=80=A2 Assorted improvements to the web interface and to logging. I=E2=80=99m regularly deploying the latest revision at using the Cuirass channel (I=E2=80=99m purposefully postponing an update of the =E2=80=98cuirass=E2=80=99 package = until I=E2=80=99ve acquired more experience and confidence.) If you=E2=80=99re running an ins= tance of Cuirass and feeling adventurous, you can try it as well: (cons* (channel (name 'cuirass) (url "https://git.savannah.gnu.org/git/guix/guix-cuirass.git") (introduction (make-channel-introduction "c75620777c33273fcd14261660288ec1b2dc8123" (openpgp-fingerprint "3CE4 6455 8A84 FDC6 9DB4 0CFB 090B 1199 3D9A EBB5")))) %default-channels) With these architectural changes, we should be able to make more visible improvements such as adding web hooks (so a Git repo can trigger a new evaluation), replacing polling with notifications in many cases, adding a Build Coordinator backend (convergence!), etc. See . Contributions welcome! :-) Ludo=E2=80=99.
