hercules-ci-agent-0.6.3

Fixed

• Fix a concurrency problem causing not all evaluation events to be written to server when evaluation fails.

• Fix evaluation errors triggered by build outputs go missing from cache, by requesting a forced rebuild.

• Fix blocked shutdown on NixOS, fix agent status in dashboard, by stopping agent before network shutdown #195.

• Fix upload of large outputs by using the correct http client manager for Cachix, removing a timeout.

Changed

• Agent will now try to verify that the nix-daemon has narinfo-cache-negative-ttl = 0. This is required for correct operation.

hercules-ci-agent-0.6.2

Fixed

• Update cachix to support the API change for the new CDN. This update is required for uploading sources and compressed outputs over 100MB in size. Please update.

hercules-ci-agent 0.6.1

Fixed

• Fix token leak to system log when reporting an HTTP exception. This was introduced by a library upgrade.
  This was discovered after tagging 0.6.0 but before the release was
  announced and before moving of the stable branch.
  Only users of the hercules-ci-agent master branch and the unannounced
  tag were exposed to this leak.
  We recommend to follow the stable branch.

• Temporarily revert a Nix GC configuration change that might cause problems
  until agent gc root behavior is improved.

hercules-ci-agent 0.6.0

Changed

• Switch to Nix 2.3 and NixOS 19.09. You should update your deployment to reflect the NixOS upgrade, unless you're using terraform or nix-darwin, where it's automatic.
• Increased parallellism during push to cachix
• Switch to NixOS 19.09
• Enable min-free/max-free Nix GC

Fixed

• Transient errors during source code fetching are now retried
• Fixed a bug related to narinfo caching in the context of IFD
• Fixed an exception when the root of ci.nix is a list, although lists are unsupported

hercules-ci-agent 0.5.0

Added

• Now deployable with terraform-hercules-ci

Changed

• The binary-caches.json file can now be deployed like any other confidential file. Its contents are not required at module evaluation time any more.

• The services.hercules-ci-agent.binaryCachesFile option has been removed.

  NixOps users: rename to deployment.keys."binary-caches.json".file

  Others: remove your binaryCachesFile value. Make sure binary-caches.json is deployed.

• The binary-caches.json file is now required. The empty object {} is a
  valid file, but we highly recommend to configure a cache.

Fixed

• The agent will now actually auto-restart when the secrets files change.

hercules-ci-agent 0.4.0

Added

• Support for import-from-derivation. See https://blog.hercules-ci.com/2019/08/30/native-support-for-import-for-derivation/ for details.

Changed

• Report build failures and technical errors (misconfigurations, etc) separately

• Remove HerculesScribe

• Worker now uses structured logging (including worker pid, etc)

Fixed

• Disable parallel GHC GC to improve runtime performance

• Bump Cachix to fix a few bugs (errors with too many derivations, performance fixes, etc.)

• Modern BoehmGC initial settings for Nix memory limits

hercules-ci-agent 0.3.2

Fixed

• Deploying the agent from different system (darwin to linux) resulted into using the wrong executable

hercules-ci-agent 0.3.1

Changed

• Emit a log when evaluator starts to push to cachix

• Increase attribute limit to 50k

• Pin nixpkgs commit and speed up compilation via https://hercules-ci.cachix.org

Fixed

• Possible exception during evaluation was not propagated,
  resulting into lack of retries

• #8: Refresh agent session on cluster join token change

• Fix segfault on involved IFD project (remove a finalizer)

• Cachix: fix a crash with a lot of attributes (when determining closure graph)
