emacs-app-devel build fail on master not detected by buildbot

[Nathaniel W Griswold]

Thank you, Christopher.

Are you saying the date-style depth would be the right way forward? That seems fine and then the maintainers could either keep up or not. The current idea of using the breakage event as a signal to update the port file is kinda bad IMO.

If the port no longer builds because the referenced commit is more than 1,000 commits in the past, then the port is ripe for a bump. Increasing the depth or using a date-based strategy will just balloon the amount of data fetched.

Since the clone produced from the Portfile uses depth 1000, This means that port cannot check out that commit in its local checkout and the port build fails on that step.

If a git clone with a —depth=${val} is found in the Portfile for a port or subport, then the build system could trigger a build periodically at some rate that doesn’t stress the build setup too much. I don’t know how many Portfiles have `git clone —depth=${val} ${repo}` git.url values but if there aren’t that many you could trigger these builds quite often.
