This is useful as the author of the original PR doesn't necessarily
have (write) access to the repository where the forward-port PR was
created. As a result, while they can r+ the PR they're unable to close
it (via github's interface).
Since the forwardport bot created the PR, it can also close it, which
seems like a useful feature.

As the odds of having more projects or more repos with different
requirements in the same project, the need to have different sets of
reviewers for different repositories increases.
As a result, rather than be trivial boolean flags the review info
should probably depend on the user / partner and the repo. Turns out
the permission checks had already been extracted into their own
function so most of the mess comes from testing utilities which went
and configured their review rights as needed.
Incidentally it might be that the test suite could just use something
like a sequence of commoditized accounts which get configured as
needed and not even looked at unless they're used.
If a new branch is added to a project, there's an issue with *ongoing*
forward ports (forward ports which were not merged before the branch
was forked from an existing one): the new branch gets "skipped" and
might be missing some fixes until those are noticed and backported.
This commit hooks into updating projects to try and see if the update
consists of adding a branch inside the sequence, in which case it
tries to find the FP sequences to update and queues up new
"intermediate" forward ports to insert into the existing sequences.
Note: had to increase the cron socket limit to 2mn as 1mn blew up the
big staging cron in the test (after all the forward-port PRs are
approved).
Fixes#262
[FIX]
Add handling of branch filtering to the forwardport module:
* don't forward port (and trigger an error) when trying to port
PRs to different next targets
* otherwise port normally
e.g. given a project with repos A and B and branches a, b and c, with
branch b being excluded from repo B:
* a PR merged into A.a will be forward-ported to A.b and A.c
* a PR merged into B.a will be forward-ported to B.c (skipping the
excluded B.b)
* a PR set merged into (A.a, B.a) will *not* be forward-ported, and a
message will be posted to each PR denoting the incompatibility
Test is probably more complex than necessary (thinking about it, the
failed staging is probably unnecessary) but that triggers the issue
and matches the original scenario.
The problem was really with new CI events being received on the last
forward-port PR of a sequence: previous PRs would have a child PR so
the check would abort, but for the last PR it would go through, fail
to find an active batch, then blow up as it tries to create a
forwardport.batch without an actual batch.
Change this to use the existence of an inactive batch not linked to a
staging as a flag that the PR has been processed and forward-ported.
Closes#218
* Cherrypicking is handrolled because there seems to be no easy way to
programmatically edit commit messages during the cherrypicking
sequence: `-n` basically squashes all commits and `-e` invokes a
subprocess. `-e` with `VISUAL=false` kinda sorta works (in that it
interrupts the process before each commit), however there doesn't
seem to be clean status codes so it's difficult to know if the
cherrypick failed or if it's just waiting for a commit of this step.
Instead, cherrypick commits individually then edit / rewrite their
commit messages:
* add a reference to the original commit
* convert signed-off-by to something else as the original commit was
signed off but not necessarily this one
* Can't assign users when creating PRs: only repository collaborators
or people who commented on the issue / PR (which we're in the
process of creating) can be assigned.
PR authors are as likely to be collaborators as not, and we can have
non-collaborator reviewers. So pinging via a regular comment seems
less fraught as a way to notify users.
