Import form refuses Mercurial URLs
In GitLab 13.12 (Heptapod 0.23), there is a validation that the URL ends in .git
, which seems to be too harsh. This is the probable cause.
In any case, this validation changes with GitLab 14.1 (perhaps in 14.0 already), and we'll test it manually, or, better, introduce a Selenium test.
Note: there are functional tests for imports already, but they rely on the REST API.
