Build custom packages with cuirass.

Build custom packages with cuirass.

Hi,

I'm trying to use cuirass to build all the packages of my current
manifest on top of guix master periodically.

Some of my packages are custom, so I need cuirass to be aware of
GUIX_PACKAGE_PATH env variable.

The only way I found is to patch cuirass service (cf. following patch).
Is this a good idea ? Is someone doing this kind of stuff here ?

Thank you,

Mathieu

A quick and dirty way to fix your issue would be to add the absolute
base directory name for your custom package modules in the '#:load-path'
part of you specification.  However this will only work if your modules
names are '(gnu packages ...)'.

I guess Cuirass should handle this use case with '-L', '--load-path'
command line arguments like what 'guix build' does.  WDYT?

Would you be interested in implementing this?

Thanks.

Yes, it would be better than my initial idea.

Yes of course :)

Using cuirass I also noticed two other things that might need to be fixed:

* When network isn't up yet at cuirass service start,
or goes down for a moment, the url fetching
fails and cuirass service stays hanged and needs to be restarted.

* For an unknown reason, I have random freezes of cuirass, the polling
  stops and nothing is outputed to log. I'm stracing it to find out why
  ...

Otherwise it works fine for me !

I have created 2 separate issues on Notabug Web interface to track those
bugs:

Thanks for reporting them.
