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.
Setting
xxx-jobset-repeats = patchelf:master:2
will cause Hydra to perform every build step in the specified jobset 2
additional times (i.e. 3 times in total). Non-determinism is not fatal
unless the derivation has the attribute "isDeterministic = true"; we
just note the lack of determinism in the Hydra database. This will
allow us to get stats about the (lack of) reproducibility of all of
Nixpkgs.
Builds can now specify the attribute "isDeterministic = true" to tell
Hydra to build with build-repeat > 0. If there is a mismatch between
rounds, the step / build fails with a suitable status.
Maybe this should be a meta attribute, but that makes it invisible to
hydra-queue-runner, and it seems reasonable to make a claim of
mandatory determinism part of the derivation (since e.g. enabling this
flag should trigger a rebuild).
We now take into account the memory necessary for compressing the NAR
being exported to the binary cache, plus xz compression overhead.
Also, we now release the memory tokens for the NAR accessor *after*
releasing the NAR accessor. Previously the memory for the NAR accessor
might still be in use while another thread does an allocation, causing
the maximum to be exceeded temporarily.
Also, use notify_all instead of notify_one to wake up memory token
waiters. This is not very nice, but not every waiter is requesting the
same number of tokens, so some might be able to proceed.
