In a NixOS container, cmdBuildDerivation doesn't work because we're
not privileged. But we also don't need it because the store already
has the derivation.
Also, don't copy from/to the store since this gives errors about
missing signatures.
It contains Hydra, PostgreSQL and an frontend proxy. So you can get a
running Hydra instance by doing
$ nixos-container create hydra --flake hydra
$ nixos-container start hydra
The web interface is available on port 80.
This removes a supper annoying set of messages that polute the logs:
Aug 30 09:00:30 xxx.compute.internal hydra-server[957]: Trouble trying to detect your terminal size, looking at $ENV{COLUMNS}
Aug 30 09:00:30 xxx.compute.internal hydra-server[957]: Term::Size::Any is not installed, can't autodetect terminal column width
This attribute allows to know if an error occurred or not: when an
error occurs, errormsg is not an empty string. Note we can not use the
errormsg attribute because it can be arbitrarily long and is excluded
from the jobset API response.
This adds the following (pre-existing) attributes to the jobset response:
- nrtotal
- lastcheckedtime
- starttime
- checkinterval
- triggertime
- fetcherrormsg
- errortime
May 15 09:20:10 chef hydra-queue-runner[27523]: Hydra::Plugin::GitlabStatus=HASH(0x519a7b8)->buildFinished: Can't call method "value" on an undefined value at /nix/store/858hinflxcl2jd12wv1r3a8j11ybsf6w-hydra-0.1.2629.89fa829/libexec/hydra/lib/Hydra/Plugin/GitlabStatus.pm line 57.
(cherry picked from commit 438ddf5289)
Plugins are now disabled at startup time unless there is some relevant
configuration in hydra.conf. This avoids hydra-notify having to do a
lot of redundant work (a lot of plugins did a lot of database queries
*before* deciding they were disabled).
Note: BitBucketStatus users will need to add 'enable_bitbucket_status
= 1' to hydra.conf.
