[PATCH 0/2] Add a test for the Prosody service.

[PATCH 0/2] Add a test for the Prosody service.

[Clément Lassieur]

These patches add a test for the Prosody service.  I chose to use GNU Freetalk
as the XMPP client because it is scriptable through a Guile interface.

Thanks for your feedback!

Clément Lassieur (2):
  service: shepherd: Replace spaces with hyphens in file names.
  tests: Add 'prosody-service-type' test.

[PATCH 1/2] service: shepherd: Replace spaces with hyphens in file names.

[Clément Lassieur]

* gnu/services/shepherd.scm (shepherd-service-file-name): Update
  'match-lambda' accordingly.

This fixes a bug whereby names of files defining services would be invalid if
'provisions' contained more than one element.

Maybe I should add a timeout somewhere, so the test doesn't wait forever
if the message is not actually received.  WDYT?

Please also add the new file to gnu/local.mk.

I think you can remove ‘os-with-service’ and simply add the Prosody
service explicitly in ‘%base-os’ (which could be rename ‘%prosody-os’
maybe).

Very neat that this can be done in Scheme too.  :-)

If it’s possible, I agree that adding a timeout (say 1 minute) would be
nice.

I think (file-exists? (string-append "/proc/" pid)) would be enough.

Better use ‘match’ here.  :-)

   (match (command-line)
     ((command jid password)
      …))

Could you send an updated patch?

Thank you!

But then, my test wouldn't be generic anymore, would it?  I would like
it to be Prosody-independent, so that one can add, say, the ejabberd
service easily.  That's why I call the service 'xmpp-daemon' instead of
'prosody'.  WDYT?

I think you’re right.  :-)  I didn’t know you had this in mind, but it’s
a good idea.
