Drone 2.0 - Push to main is being ignored

Drone Support

We have just updated to Drone 2.0rc and noticed that some builds are being ignored. The gist of our process is we open a PR to main and the PR build is running just fine. When the PR is merged it should trigger a build with the push to main. However, depending on the commit some builds appear to be ignored.

It appears to be related to a custom tag we put in our commit body that our builds use to bump the semantic version. For example @bump_minor@ or @bump_major@. Specifically it seems to be if any line in the commit message starts with an @ the push to main gets ignored.

these work
just a commit title

build: kick the build

commit title with a body and the tag at the end of the line

build: kick the build

maybe we need more body here? @bump_minor@

these dont
commit title and body is only the bump tag

build: kick the build

@bump_minor@

commit title, multi-line body where tag is at the start of the line

build: kick the build

maybe we need more body here? 

@bump_minor@

We saw in the logs that it said webhook ignored after receiving the /hook POST.

I recommend using this thread to debug:

This is unlikely related to 2.0 because the 2.0 release consists of frontend (UI) changes only. There haven’t been any recent changes to webhook processing code.

It is also normal to see webhook ignored messages in the logs since Drone ignores some webhoks by design (like branch delete, pr delete, etc).
