Changelog

0.36.0

Release 2024-10-03

  • Adds a link to the readme when reporting parse errors. (#269)
  • In simple cases, successful commands will now trigger a 👍 reaction instead of a comment. (#272)

0.35.1

Release 2024-06-17

  • Fixes an issue with retying failed PRs after a priority merge.

0.35.0

Release 2024-06-05

  • Adds APi endpoint to get project status

0.34.0

Release 2024-04-25

  • Adds the option to jump the merge train. This can be done using with priority at the end of the merge command.
  • Adds the merge priority to the merge commit message as Priority: <priority>.

0.33.2

Release 2024-03-29

  • Fixes a bug where the parser didn't backtrack when one of the configured environments or subprojects is a prefix of another.

0.33.1

Release 2024-03-12

  • Adds a list of recently promoted PRs to check if a push to master is one of these recently promoted PRs.

0.33.0

Release 2024-01-13

Compatibility:

  • The state serialization format of previous versions is incompatible with 0.33.0. The recommended way to update is to stop Hoff at a quiet time when no builds are in progress, delete the state files, and start 0.33.0. The new version of Hoff will automatically create a new state file using the new format when run.

Changes:

  • Add Deploy-Subprojects: <subprojects> to merge commit messages of PRs approved with the merge and deploy command. is a comma-separated subset of the configured subprojects of the project, or the string "all".
  • The merge and deploy command now accepts a comma-separated list of subprojects. If no subprojects are configured or passed to the command, all is assumed.
  • Subprojects can be configured per repository in your config.json under deploySubprojects.

0.32.3

Release 2024-01-03

  • Add 'auto-refresh' button to web UI which, when turned on, refreshes the web UI every few seconds to make it easier to stay informed of Hoff's progress. (This change only touches the web UI. No changes in Hoff's functionality itself.)

0.32.2

Release 2023-12-14

  • Wait with promoting to master until the PR has been updated after the force push.

0.32.1

Release 2023-11-28

  • Push integration results atomically to avoid PRs being closed incorreclty.

0.32.0

Release 2023-11-07

  • Add featureFreezeWindow configuration option. During a configured feature freeze, only commands suffixed with as hotfix are allowed. The feature is similar to the on friday feature.

0.31.11

Release 2023-10-26

  • Disallow merge and deploy without a specified environment if multiple environments are available.

0.31.10

Released 2023-10-26

  • Always create merge commits when a single-commit PR is approved for merge and tag.

0.31.9

Released 2023-10-23

  • Allow a merge command in the description of a merge request, to be able to directly create a pull request and approve it for merging.

0.31.8

Released 2023-10-16

  • Restart integration after a push to the target branch. This is to prevent waiting on CIs that are not up to date anymore.
  • Respond with 204 (NoContent) instead of 501 (UnImplemented) when responding to unsupported event hook types sent by Github. This is to prevent Github from interpreting the responses as errors.
  • Log unsupported event hook types to STDOUT>.

0.31.7

Released 2023-10-10.

  • Increased internal event queue sizes from 10 to 128 to reduce the chance of Hoff dropping events when receiving dozens of webhook events at the exact same time.
  • When Hoff drops a webhook event because its internal event queue is full, it will now log the evenet to STDOUT>

0.31.6

Released 2023-10-05.

  • Fix fat-fingering the number version in the cabal file.

0.31.5

Released 2023-10-05.

  • Avoid corrupting the internal project state when a merge command is issued multiple times. Now, issuing a merge command on a pull request that is in progress of being integrated, the entire pull request's state is reset and the new merge command is processed.

0.31.4

Released 2023-06-09.

  • Fixed a regression from 0.31.3 where links in Hoff's messages are not properly displayed on GitHub.

0.31.3

Released 2023-06-07.

  • Changed the build system to use plain Cabal instead of Stack. Check the readme for more details.
  • Prevent Hoff from replying to its own feedback messages. This is relevant when the command prefix is set to the bot's username, and the merge command was posted from that same account. Before this change Hoff would reply with a harmless but annoying parser error message.

0.31.2

Released 2023-05-23.

  • Fixed a regression from 0.31.0 where Hoff would enter a feedback loop when posting a parser error message, as those error messages also contain Hoff's command prefix.

0.31.1

Released 2023-05-22.

  • Fixed mismatching version numbers in the Nix build.

0.31.0

Released 2023-05-22.

  • Added a new, stricter parser that posts clear error messages when the comment contains invalid merge commands. This avoids situations like @hoffbot merge and deploy to foobar causing a deploy to the default environment as Hoff would previously simply match the @hoffbot merge and deploy part. Merge commands now need to be either on their own line, or at the end of a line optionally followed by some punctuation.
  • There is now a @hoffbot retry command to retry merges with failing test. This is equivalent to closing the PR, reopening the PR, and then asking the bot to initiate the merge again, but in a single step and without actually closing the PR first.

0.30.0

Released 2023-05-15.

  • Hoff no longer prints the internal state any time it receives an event.
  • Hoff's internals have been rewritten using effectful.

0.19.2

Released 2021-05-02.

  • Updated the Nix builds to use GHC 9.2.

0.19.1

Released 2021-04-12.

  • Fixed URLs to tag pages on GitHub.

0.19.0

Released 2021-02-12.

  • Hoff now interprets instructions left through a pull request review, so you can say “@bot merge” directly from a review. This applies to the overall review body, not to individual review comments left on the diff. Hoff ignores the status of the review (approval, changes requested, etc.), it only looks for the “@bot merge” command.

0.18.0

Released 2021-01-27.

Compatibility:

  • The state serialization format of 0.18.0 is incompatible with 0.17.0. The recommended way to update is to stop Hoff 0.17.0 at a quiet time when no builds are in progress, delete the state files, and start 0.18.0. Hoff will scan for open pull requests at startup, but approval status will be lost.

    The new version of Hoff will automatically create a new state file using the new format when run.

Changes:

  • Add Auto-deploy: false as a Git trailer to merge commit messages of PRs approved with the "{prefix} merge" command.

    This change does not affect single-commit PRs, as these are merged by fast-forwarding the target branch and don't have a merge message.

  • Add support for a new merge command "{prefix} merge and deploy".

    When this command is used Hoff will perform a rebase and merge in the same way as is done in response to the "merge" command.

    Unlike the "merge" command, Hoff will

    • Always create a merge commit, even for single-commit PRs, and

    • Append Auto-deploy: true (instead of Auto-deploy: false) to the commit message of the resulting merge commit.

      This information can later be used in a CI/CD pipeline to trigger an automatic deploy.

0.17.0

Released 2021-01-06.

  • Include pull request title in the merge commit message.

0.16.0

Released 2020-08-05.

Compatibility:

  • The state serialization format of 0.16.0 is incompatible with 0.15.0. The recommended way to update is to stop Hoff 0.15.0 at a quiet time when no builds are in progress, delete the state files, and start 0.16.0. Hoff will scan for open pull requests at startup, but approval status will be lost.

Bugfixes:

  • Hoff will no longer incorrectly leave a comment that it will rebase a pull request after re-approving a pull request that failed to build. It now re-reports the build failure in the reply instead. Close and re-open the pull request to clear the build status.

0.15.0

Released 2020-06-29.

Compatibility:

  • The state serialization format of 0.15.0 is incompatible with 0.14.0. The recommended way to update is to stop Hoff 0.14.0 at a quiet time when no builds are in progress, delete the state files, and start 0.15.0. Hoff will scan for open pull requests at startup, but approval status will be lost.

Other changes:

  • The bot user will now leave a comment when it abandons a pull request that was being integrated.
  • Unhandled exceptions now crash the process, instead of only the thread. This means failures are now loud, rather than processing slowly grindinding to a halt due to bounded queues filling up.
  • Fix a crash that could happen when pushing a previously successfully rebased pull request failed (because something else was pushed in the meantime), and a new rebase attempt ended with a conflict.

0.14.0

Released 2020-03-27.

  • Fix formatting typo in the comment that the bot leaves on a failed rebase.

0.13.0

  • The bot user will now comment with detailed instructions on how to rebase, if the automated rebase fails.
  • Synchronize the state with GitHub at startup. It is no longer necessary to close and reopen a pull request if a webhook delivery was missed, restarting Hoff should bring everything in sync again.
  • The binary now accepts --read-only, which will prevent disruptive side effects such as pushing and leaving comments, but it will still pull, and make API calls to the GitHub API that only read data. This is useful for local development, or for a dry run of a new setup.

0.12.0

  • Compatibility: The schema of the state files has changed. Hoff v0.12.0 can read v0.11.0 state files, so an upgrade is seamless, but a downgrade would require manual intervention.
  • Fix bug where Hoff would stop to try merging, after pushing to master fails because something else was pushed to master meanwhile.

0.11.0

  • Accept merge command anywhere in comments.
  • Take dependencies from Stackage LTS 14.21, up from 9.0.

0.10.0

  • Do not delete branches after merging a pull request, GitHub has that functionality now, and it can interfere with dependent pull requests.
  • Add overview pages that show everything in all repositories of an owner on one page.
  • Fix a bug in the queue position comment that the bot leaves.
