Status: RESOLVED FIXED

(Developer Services :: Mercurial: hg.mozilla.org, defect)

Description

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

https://hg-edge.mozilla.org/integration/autoland/rev/92bf770c26f031ef3fe51f63d31b3b16ab47c30d only loads the in-page headers and stops when the actual patch content shall be submitted.

Julien identified the regressor and will look at this on Thursday. This is the stacktrace he provided:

When revsingle is passed an empty revset it raises InputError, so catch
that case for when the referenced git commit either doesn't exist or is
further back than the backoutsearchlimit.
