When using the "build" or "sysbuild" jobset input types in conjunction
with a binary cache store, the evaluator needs to be able to fetch
store paths from the binary cache. Typical usage:
store_uri = s3://nix-test-cache?secret-key=...
eval_substituter = s3://nix-test-cache
Also, the public key of the binary cache must be added to
binary-cache-public-keys in nix.conf, otherwise the local nix-daemon
won't allow the store paths to be copied over.
Also, remove support in hydra-eval-jobs for multiple jobset input
alternatives. The web interface hasn't supported this in a long
time. Thus we can use the regular "--arg" handler.
This makes downloading/viewing build results work with binary cache
stores. For good performance, this should be used in conjunction with
ca580bec35,
i.e. you should set store_uri to something like
s3://my-cache?local-nar-cache=/tmp/nar-cache
to cache NARs between requests.
When creating a Hydra user with the `hydra-create-user` command, you can now
provide a SHA1 password hash with the `--password-hash` flag. This is useful for
the upcoming work on Fully Declarative Hydra, since the end user should not have
to specify plaintext passwords in their `configuration.nix` file.
Thus, we no longer hold the send lock while substituting missing paths
on the build machine. This is a good thing in particular for macOS
builders which have a tendency to hang forever in curl downloads.
Previously, when hydra-queue-runner was restarted, any pending "build
finished" notifications were lost. Now hydra-queue-runner marks
finished but unnotified builds in the database and uses that to run
pending notifications at startup.
The queue runner can now run up to ‘max-concurrent-notifications’ in
parallel (default is 2). This is useful when some hydra-notify
invocations can take a long time to complete (e.g. because they need
to compress a giant build log) and we don't want this to block all
other notifications.
As @dtzWill discovered, with the concurrent hydra-evaluator, there can
be multiple active transactions adding builds to the database. As a
result, builds can become visible in a non-monotonically increasing
order, breaking the queue monitor's assumption that build IDs only go
up.
The fix is to have hydra-eval-jobset provide the lowest build ID it
just added in the builds_added notification, and have the queue
monitor check from there.
Fixes#496.
This plugin will post to the build status system in BitBucket. In order
to use it you need to add to ExtraConfig
<bitbucket>
username = bitbucket_username
password = bitbucket_password
</bitbucket>
You can use an application password https://blog.bitbucket.org/2016/06/06/app-passwords-bitbucket-cloud/
This can take an excessive amount of time. For example, on
hydra.nixos.org, a call to hydra-notify takes 0.7s even if there are
no plugins. So for an eval with ~45K new builds, the calls to
hydra-notify add up to about 9 hours.
The proper fix would be to pass a list of build IDs, or an eval ID.
This can be used with declarative projects to build PRs.
The github_authorization section should contain verbatim Authorization header contents keyed by repo owner for private repos
1. From the hydra configuration file.
The configuration is loaded from the "git-input" block.
Currently only the "timeout" variable is been looked up in the file.
<git-input>
# general timeout
timeout = 400
<input-name>
# specific timeout for a particular input name
timeout = 400
</input-name>
# use quotes when the input name has spaces
<"foot with spaces">
# specific timeout for a particular input name
timeout = 400
</"foo with spaces">
</git-input>
2. As an argument in the input value after the repo url and branch (and after the deepClone if is defined)
"timeout=<value>"
The preference on which value is used:
1. input value
2. Block with the name of the input in the <git-input> block
3. "timeout" inside the <git-input> block
4. Default value of 600 seconds. (original hard-coded value)
The code is generalized for more values to be configured, it might be too much
for a single value on a single plugin.
Adding a 96-core aarch64 build machine to the build farm caused the
potential number of database connections to increase a lot, so we
started hitting the Postgres connection limit.
* The "Jobset" page now shows when evaluations are in progress (rather
than just pending).
* Restored the ability to do a single evaluation from the command line
by doing "hydra-evaluator <project> <jobset>".
* Fix some consistency issues between jobset status in PostgreSQL and
in hydra-evaluator. In particular, "lastCheckedTime" was never
updated internally.
