2022-06-03 r/4203 refactor(nix/buildkite): Explicit support for build phasesVincent Ambo1-63/+108
Previously the extra steps were roughly divided into steps that run "at build time" (i.e. before we publish results to Gerrit), and "post-build" (i.e. later on). In practice, these are something like a build/release pairing, where steps running after the build results are returned are mostly run for side-effects (e.g. publishing git subtrees to external repos). This refactoring makes this distinction explicit in //nix/buildkite and changes the extraSteps API with an explicit `phases` attribute instead of the previous `postStep` attribute. In practice the previous API is still supported, but will throw evaluation warnings until an arbitrarily chosen cutoff date of 2022-10-01 at which point we will change using it into a hard error. This uncovered a few strange behaviours which we only accidentally avoided, most of which I have left TODOs about and will clean up in subsequent commits. The purpose of this commit is to allow for separate evaluations of only build or only release steps, for example if release steps are evaluated in a slightly different context (e.g. with overridden versioning that is not relevant to standard CI functionality).

The isPowerPC predicate has been [removed], since it was misleadingly named (it just matches PowerPC, 32bit, little endian). This means the 64bit code path could now actually work.

I want to use this utility in a deploy script where the .drv is nix-copy-closure-d to a remote host and realized there. Consequently it doesn't make sense that the local deploy script depends on the derivation's outputs which drvPath does by default. This also came up when working on //nix/buildkite, although we didn't end up using it there.

Due to [nix#6579] the heuristic which allowed us to determine if a symlink points to a directory is not reliable – if restrict-eval is enabled it _will_ return wrong results.

2022-05-02 r/3996 feat(nix/lazy-deps): Add function to generate lazy binary dispatcherVincent Ambo1-0/+75
There is a reoccuring problem in readTree-type repositories that use nix-shell, where evaluation of the full set of dependencies that should be made available to users takes a noticeable amount of time, slowing down operations when `direnv` is involved. In depot, we have so far fixed this by maintaining a manual `//bin` directory which contains a set of symlinks to a central dispatch script that can dispatch to various tools in depot lazily. This script can instead be generated ad-hoc by Nix (pretty fast if we can make assumptions like `git` and `nix-build` existing on user's machines already) and added to $PATH. The function introduced in this commit implements the logic for that. The structure of the script is based on the existing `//bin/__dispatch`. This does not yet switch depot's envrc to use this new method of installing dependencies lazily.

This can lead to flaky behaviour where it returns no results and fails if `git gc` recently ran (Buildkite will do this occasionally). Though the parameter is semantically closer to what we're looking for, the output is *usually* the same commit since we're not dealing with more than one thing to compare.

2022-01-20 r/3640 fix(nix/buildkite): prevent swallowing errors from git-merge-baseVincent Ambo1-5/+7
The `local` usage we had before would silently swallow non-zero exit statuses from the substituted git commands. For some (as of yet unknown) reason, `git merge-base` seems to sometimes silently fail and produce no output, which broke the rest of the script logic. This change will lead to an earlier error, but we don't know if it is a fix for the actual cause of the git-merge-base problem because the shape of that problem is unclear.

2022-01-17 r/3602 feat(nix/buildkite): Check target map of parent to determine skipsVincent Ambo1-22/+22
This changes the logic for build pipeline generation to inspect an (optional) parentTargetMap attribute which contains the derivation map of a target commit. Targets that existed in a parent commit with the same drv hash will be skipped, as they are not considered to have changed. This does not yet wire up any logic for retrieving the target map from storage, meaning that at this commit all targets are always built. The intention is that we will have logic to fetch the target map (initially from Buildkite artefact storage), which we then pass to the depot via externalArgs when actually generating the pipeline.

2022-01-17 r/3601 feat(ops/pipelines): Create drvmap structure for each commitVincent Ambo1-3/+23
Always create a structure that maps all targets to derivations, and persist it as a JSON file. This relates to some of the ideas expressed in: https://docs.google.com/document/d/16A0a5oUxH1VoiSM8hyFyLW0WiUYpNo2e2D6FTW4BlH8/edit The file is always uploaded to Buildkite as an artifact. This allows for retrieving it based on the commit ID in a Buildkite GraphQL query. By default, Buildkite stores artefacts for 6 months. Storage location can be overridden (with custom retention) through some environment variables, but for now at TVL the Buildkite-managed storage is fine. See also: https://buildkite.com/docs/pipelines/artifacts In the subsequent filtering implementation, when diffing commits across a time-range that exceeds artefact retention time, we should simply default to building everything.

while trying to yantsify `mkSecrets` in https://cl.tvl.fyi/c/depot/+/4688, I(zseri) needed to debug a failing evaluation which boiled down to a result.ok containing something which wasn't boolean, but the error message didn't indicate where that value came from. I debugged yants and found that the only place which didn't simply combine boolean values or use functions which always return booleans, I managed to isolate the error to the `pred v` expression. To avoid the necessity to debug yants to find this, I improve the error message for this case to mention that - a restriction predicate is invalid - what's the name of the failing restriction - the unexpected predicate return value Change-Id: I6c570a33ccc5afc445f208e2e8855c49fb37abaf Reviewed-on: https://cl.tvl.fyi/c/depot/+/4698 Tested-by: BuildkiteCI Reviewed-by: zseri <zseri.devel@ytrizja.de> Reviewed-by: tazjin <mail@tazj.in> Autosubmit: zseri <zseri.devel@ytrizja.de>

These targets would be the same derivation, but named differently which is noisy and causes a few, mostly subtle issues: * Buildkite struggles with large pipelines a bit, we can save quite a few steps by removing these. * Having two jobs for the same derivation sometimes causes the annoying situation that an agent would do nothing except waiting for a lock. * Non-nix CI we add in the future may not be able to recognize that these targets are the same and do extra work unnecessarily.
