[FIX] : prevent merging conflicts commits with loss of authorship Proper attribution is important in general, but especially for external contributors. Before this change, and the previous change fixing authorship deduplication, it was rather easy for a "squashed" conflict commit (attributed to the 'bot for lack of a really clean option) to get merged by mistake. This commit changes two things: The mergebot now refuses to stage commits without an email set, the github API rejects those commits anyway so any integration mode other than `merge` would fail, just with a very unclear error * The forwardbot now creates commits with an empty author / committer email when the pull request as a whole has multiple authors / committers. This leverages the mergebot update. Also clean up the staging process to provide richer error reporting using bespoke exceptions instead of simple assertions. I'm not sure we've ever encountered most of these errors so they're really sanity checks but the old reporting would be... less than great. Fixes #505 2021-08-03 18:45:21 +07:00			`class Mismatch(MergeError):`
[FIX] mergebot: improve handling of having missed PR updates 1. if we try to stage a PR and realize we'd stored / checked the wrong head, cancel the staging and notify the PR 2. provide a command to forcefully update pr heads (or at least check that a PR's head is up to date) Closes #241 2019-11-20 20:57:40 +07:00			`pass`

[CHG] runbot_merge: make merge method non-blocking Because of the false negatives due to github's reordering of events on retargeting, blocking merge methods can be rather frustrating or the user as what's happening and how to solve it isn't clear in that case. Keep the warnings and all, but remove the blocking factor: if a PR doesn't have a merge method and is not single-commit, just skip it on staging. This way, PRs which are actually single-commit will stage fine even if the mergebot thinks they shouldn't be. Fixes #957 2024-10-07 13:07:59 +07:00			`pass`
