Automated references
--------------------
For example let's say you fixed [Bugzilla Issue 16582](https://issues.dlang.org/show_bug.cgi?id=16582)
and make a PR for on GitHub.
If one of your commits mentions the issue, e.g. like this Git commit message:
```
fix Bugzilla Issue 16582 - ParameterDefaults fails w/ scope parameter
```
The Dlang-Bot will do all the hard work of linking and referencing
between Bugzilla, GitHub and Trello do for you.
### GitHub
It would comment on GitHub with list of all mentioned issues and link them to Bugzilla:
The first column of the table is the current status of the referenced issue.
A `✗` means that the issue is only mentioned (i.e. the commit message doesn't contain "Fix")
and the Bugzilla issue won't be auto-closed nor listed in the changelog as fixed:
### Trello
For the [Trello board](https://trello.com/b/XoFjxiqG/active) it will also provide a
reference:
And once a PR gets merged, the bot moves the linked Trello card to "Testing / Review".
### Bugzilla
Once a PR has been merged (i.e. the commits got pushed to master or stable),
GitHub's Bugzilla integration will automatically comment to Bugzilla with a regarding commit:
It will also automatically close the referenced issues if `fix` or `fixes` (case-insensitive)
appears before the issue reference.
Using this syntax is also very important because for the changelog generation, the
git history will be used. Thus _only_ if the Dlang-Bot has detected an issue
and commented on your PR it can become part of the changelog.
In doubt, you can use e.g. [Regex101](https://regex101.com/r/vjOAM4/1) to validate your commit message.
### Referencing multiple issues
It's possible to reference multiple issues, e.g. with "Fixes issues 17494, 17505, 17506" the Dlang-Bot would detect:
Accepted optional separators are: commas (`,`), the word `and`, as well as the plus sign (`+`),
and any amount of whitespace. Dlang-Bot will aggregate all mentioned issues over multiple commits.
### Nerdy details
- one can mention multiple issues in one commit and/or multiple commits
- the exact RegEx is:
```
(?:^fix(?:es)?(?:\s+(?:issues?|bugs?))?\s+(#?\d+(?:[\s,\+&and]+#?\d+)*))|(?:(?:issues?|bugs?)\s+(#?\d+(?:[\s,\+&and]+#?\d+)*))
```
(the GitHub Bugzilla integration and the Dlang-Bot use the same RegEx to parse
git commit messages)
Auto-merge (WIP)
---------------
At the moment the Dlang-Bot supports merging via special `auto-merge` and
`auto-merge-squash` labels. The later will perform a squashed merge of all commits
in the PR into a single one.
A reviewer can toggle a PR for "auto-merge" by simply adding the `auto-merge` label
(`auto-merge-squash` respectively).
### Nerdy details
- this relies on the "restricted branches" feature of GitHub (the Dlang-Bot will
send the attempt to merge to the GitHub API)
- once a new commit event occurs (push, synchronization) the Dlang-Bot will
automatically remove set all auto-merge labels from the PR
- for status events the GitHub API doesn't allow to get an information about the
- the Dlang-Bot will then try to restart the PR on every new event.
- concerning PR of the commit (thus all potential auto-merge PRs are checked)
_Note_: at the moment the Dlang-Bot doesn't store _any_ authentication token, so
it can't perform actions on behalf of others.
Warn about common mistakes
--------------------------
The Dlang-Bot will try to detect common mistakes and warn the contributor.
Currently implemented:
- Regression fixes doesn't target `stable`
Find stalled PRs
----------------
The Dlang-Bot goes over all pull requests every day and will label PRs:
- ["stalled"](https://github.com/dlang/phobos/issues?q=is%3Aopen+is%3Apr+label%3Astalled) (PR has had no activity within 60 days)
- ["needs rebase"](https://github.com/dlang/phobos/issues?q=is%3Aopen+is%3Apr+label%3A%22needs+rebase%22) (PR has a merge conflict)
- ["needs work"](https://github.com/dlang/phobos/issues?q=is%3Aopen+is%3Apr+label%3A%22needs+work%22) (PR has more than two failing CI providers)
Currently this feature is in alpha-mode and only enabled for Phobos.
Allow PR submitters to label their PRs
---------------------------------------
Dlang-Bot detects a pre-defined set of labels in the `[]` part of PR title and will label the PRs accordingly.
Multiple labels are supported.
Currently the hard-coded set of detected labels is:
- WIP
- trivial
Send contributing advice message
---------------------------------
For all repos in the `dlang` organization Dlang-Bot provides contributing advice on a new PR:
Auto-label PRs
---------------
If a PR contains [Bugzilla references](#automated-references), the Dlang-Bot will automatically add a respective label:
Of course, other issue types can be detected as well:
Using the Dlang-Bot for your project
------------------------------------
@dlang-bot responds to GitHub events sent to its webhook.
To use the bot in your project, configure a webhook with the following settings:
- Payload URL: `https://bot.dlang.io/github_hook` (or your own instance)
- Content type: `application/json`
- Select at least these events (or all):
- Label
- Pull request
- Pull request review
- Pull request comment
- Status
For `auto-merge`:
- a respective label needs to be added (at the `dlang` repositories `#d3d3d3` is used as a label color)
- `@dlang-bot` (or your own bot) needs to have write access to the GitHub repo (GitHub's protected branches are ideal for this)
For example, `dlang/phobos` is configured as follows:
Improve the bot
---------------
Run the testsuite:
```
dub test -- --single --debug --trace --debug
```
Missing a feature?
------------------
