7781d8b09c [IMP] runbot_merge: only show required statuses in the dashboard
Apparently a long-running issue but not really a concern before the
new mergebot started sending a lot more statuses: stagings would show
a list of all statuses they received, including optional / irrelevant
statuses.

Get a list of required statuses and only show that on the staging
dropdowns.

22e18e752b [ADD] runbot_merge: allow overriding statuses
Adds an `override` mergebot command. The ability to override is set on
an individual per-context per-repository basis, similar to but
independent from review rights. That is, a given individual may be
able to override the status X on repository A and unable to do so on
repository B.

Overrides are stored in the same format as regular statuses, but
independent from them in order to persist them across builds.

Only PR statuses can be overridden, statuses which are overridable on
PRs would simply not be required on stagings.

An alternative to implementing this feature in the mergebot would be
to add it to individual status-generating tools on a per-need
basis.

Pros of that alternative:

* display the correct status on PRs, currently the PR will be failing
  status-wise (on github) but correct as far as the mergebot is
  concerned
* remove complexity from the mergebot

Cons of that alternative:

* each status-generating tool would have to implement some sort of ACL
  system
* each status-generating tool would have to receive & parse PR
  comments
* each status-generating tool would have to maintain per-pr state in
  order to track overrides

Some sort of helper library / framework ought make that rather easy
though. It could also be linked into the central provisioning system
thing.

5c1caa1a18 [IMP] runbot_merge: provide for statuses being only on PRs or stagings
Requirement for odoo/runbot#376: one can't expect there being someone
to override CI checks on stagings, so it only makes sense for checks
on PRs, which in turns requires that there could be checks only
required on PRs.

Could also be useful for features like incremental linting /
formatting, we may want to apply checks on PRs which filter on the
lines modified, but not require the entire software be reformatted at
once.

be228a5681 [IMP] runbot_merge: split status configuration into own object
Having the required statuses be a mere list of contexts has become a
bit too limiting for our needs as it doesn't allow e.g. adding new
required statuses on only some branches of a repository (e.g. only
master), nor does it allow putting checks on only branches, or only
stagings, which would be useful for overridable checks and the like,
or for checks which only make sense linked to a specific revision
range (e.g. "incremental" linting which would only check whatever's
been modified in a PR).

Split the required statuses into a separate set of objects, any of
which can be separately marked as applying only to some branches (no
branch = all branches).

b2a4da4739 [FIX] runbot_merge: update squash flag on reopen
While the head gets updated (properly), the squash flag did not which
could lead to odd results. Since a PR can only be reopened if it was
regular-pushed to (not after a force push) there are two scenarios:

* the PR updated to have 0 commits, closed, pushed to with one commit
  then reopened, after reopening the PR would be marked as !squash and
  would ask for a merge method (that's what happened with
  odoo/odoo#51763)
* the PR has a single commit, is closed, pushed to then reopened,
  after reopening the PR would still be marked a squash and potentially
  straight rebased without asking for a merge method

Nothing would break per-se but both scenarios are undesirable.

5f8ad6a626 [IMP] runbot_merge: support for merging partners w/ github_login
The logic of the partner merge wizard is to collect all relevant data
from source partners, write them to a destination partner, then remove
the sources.

This... doesn't work when the field in question has a UNIQUE
constraint (like github_login), because it's going to copy the value
from a source onto a dest which will blow the constraint, and so the
copy fails. In that case the user first has to *move over* the unique
field's value then they can use the wizard.

Just fix for the github login: take all sources, remove (and store)
their github logins, then write the login onto the dst.

An alternative would have been to *defer* the constraint, however:

* it only works on unique constraints, not unique indexes
* it requires the constraint to be declared DEFERRABLE

0b73e5c640 [IMP] fwbot: warning on r+ for failed PR
approving a PR which failed CI should trigger a feedback message since
6cb58a322d (#158), the code has not been
removed and the tests still pass.

However fwbot r+ would go through its own process for r+ which would
explain why that feedback is sometimes gone / lost (cf #327 and #336).

* make fwbot r+ delegate to mergebot r+
* add dedicated logging for this operation to better analyze
  post-mortem
* automatically ping the reviewer to specifically tell them they're idiots
* move the feedback item out of the state change bit, send it even if
  it's a useless r+ (because it's already r+'d)
* add a test for forward-ports

b96bc9a58c [FIX] runbot_merge: make github_login case insensitive
Rather than try to fix up various bits where we search & all and
wonder what index we should be using, make the column a CIText.

For mergebot the main use case would be properly handling
delegate=XXX: currently if XXX is not a case-sensitive match we're
going to create a new partner with the new github login and
give *them* delegation, and the intended target of the delegation
isn't going to work correctly.

Also try to install the citext extension if it's not in the database,
and run the database-creation process with `check=True` so if that
fails we properly bubble up the error and don't try to run tests on a
corrupted / broken DB.

742e3219a6 [IMP] runbot_merge: make review rights repo-dependent
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.

05444aaf3f [IMP] runbot_merge: downgrade PRs to priority 1 on r-
Before this change, `r-` on a pr[p=0] does essentially nothing. At
most it will unstage if the PR had been (somewhat unnecessarily) r+'d
in the past but then the PR will get re-staged immediately.

To avoid this odd behaviour, if r- is sent to a p=0 PR not only is
the PR unreviewed (if it was reviewed) it always gets unstaged, and
its priority gets reset to 1 (high priority but doesn't bypass CI and
review). Also send a comment on that subject so followers of the pr
are notified.

9d661480fc [IMP] runbot_merge: split staging cron in two
The staging cron was already essentially split between "check if one
of the stagings is successful (and merge it)" and "check if we should
create a staging" as these were two separate loops in the cron.

But it might be useful to disable these two operations separately
e.g. we might want to stop the creation of new staging but let the
existing stagings complete.

The actual splitting is easy but it turns out a bunch of tests were
"optimised" to only run the merge cron. Most of them didn't blow up
but it seems more prudent to fix them all.

The PR creation had been fixed to always validate even without a
commit found (in case there was no need for a commit), but the update

0831c899e8 [FIX] runbot_merge: the fix
The test was checking things would work properly with
required_statuses being an empty string, because I'd also forgotten an
empty field becomes stored as `False` in the database, so trying
things out live neither the PRs nor the staging would work as their
assumption that they could straight split the required_statuses would
always fail.

Update the test to better match expectations, and hopefully this is
the end of that saga.

4bdf7e5eda [FIX] runbot_merge: stagings involving repos w/o required statuses
PRs transitioning to 'ready' had been checked and tested but turns out
I had completely forgotten to test that stagings would validate
properly therefore of course they didn't.

The issue here was I'd forgotten `''.split(',')` returns `['']` rather
than `[]`, so on an empty required_statuses the staging validator
would keep looking for a status matching the context `''` and would
never find it, keeping the staging pending until timeout. So most
likely the problem could have been resolved by just adding a condition
to

    [r.strip() for r in repomap[c.sha].required_statuses.split(',')]

but I'd already done all the rest of the reorganisation by that point,
test pass and I think it's a somewhat better logic. Therefore I'll go
with that for now.

* properly handle empty required_statuses during staging validation
* remove the final postcondition, if we're missing commits which don't
  require any statuse we should not care
* expand test to include up to merging PRs
* automatically create dummy commits when creating stagings, that way
  the relevant commits are in the database (can't hurt)

PS: an other alternative would have been to filter out or skip ahead
on commits which don't require any statuses aka cmap &
required_statuse / cmap would not even have that entry

629e00a117 [IMP] runbot_merge: add related PRs to top comment
Discussing #238 with @odony, the main concern was the difficulty of
understanding if things merged in one repo were related to things
merged in an other repo: currently, knowing this requires going to the
merged PR, getting its label, and checking the PRs with the same HEAD
in the other repository to see if there's a correlation (e.g. PRs
merged around the same time).

The current structure of the mergebot makes it reasonably easy to add
the other PRs of the batch in the pseudo-headers, such that we get
links to all "related" PRs in the head commit (and links back from the
commits which is probably less useful but...)

d453943252 [IMP] *: unify gh test API between runbot and fw-bot
The fw-bot testing API should improve the perfs of mergebot tests
somewhat (less waiting around for instance).

The code has been updated to the bare minimum (context-managing repos,
change to PRs and replacing rolenames by explicit token provisions)
but extra facilities were used to avoid changing *everything*
e.g. make_commit (singular), automatic generation of PR refs, ...

The tests should eventually be updated to remove these.

Also remove the local fake / mock. Being so much faster is a huge
draw, but I don't really want to spend more time updating it,
especially when fwbot doesn't get to take advantage. A local /
lightweight fake github (as an external service over http) might
eventually be a good idea though, and more applicable (including to
third-parties).

7659293a2b [IMP] runbot_merge: update staging timeout on 'pending' CI
If the CI is greatly backed up (either insufficient capacity or jobs
spike) a timeout which is normally perfectly fine might be
insufficient e.g. given a 2h timeout, if a job normally takes 80mn but
the staging's job starts 40mn after the staging was actually created
we're sunk. And cancelling the staging once the job has finally gotten
started is not going to improve load on the CI, it just wastes a CI
slot.

Therefore assume a `pending` event denotes the actual start of the job
on the CI, and reset the timeout to start from that moment so
ci_timeout is the timeout of the CI job itself, not of the staging
having been created.

f671dcc828 [ADD] forwardbot
* 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.

b1b959d472 [FIX] runbot_merge: properly handle retarget from deactivated branch
A deactivated branch is generally treated as unmanaged which is mostly
correct except for the case of retargeting an existing PR.

When a branch is deactivated the corresponding PRs are not removed, so
it's possible to have live PRs associated with ~unmanamaged
branches. When retargeting those PRs to active branches, the mergebot
would assume there was no existing PR and would create a duplicate,
then either get completely lost (before
a84595ea04) or blow up (after the same).

Properly search amongst deactivated branches for retargeting sources
so we update the relevant PR instead of trying to create duplicates.

[FIX] runbot_merge: resync tags on stage change
Before this change mergebot assumes github's tags are in sync with its
"previous" state, but because tags update was highly non-atomic (one
call per removal plus one for additions) and state can further change
between a failure and an update retry (especially as the labels endpoint
fails *a lot*), it's possible for set tags (in github) to be completely
desync'd from the mergebot state, leading to very misleading on-pr
indications.

This first fetches the current tagstate from github (to not lose non-
mergebot tags) then (hopefully atomically) resets all tags tags based on
the current mergebot state. This should avoid desyncs, and eventually
resync PRs (if they change state).

5aa9f5a567 [IMP] runbot_merge: extract commit validation to cron
Before this, impacting a commit's statuses on the relevant PR or
staging would be performed immediatly / inline with its
consumption. This, however, is problematic if we want to implement
additional processing like #87 (and possibly though probably not #52):
webhook handlers should be kept short and fast, feeding back into
github would not be acceptable.

- flag commits as needing processing instead of processing them
  immediately, this uses a partial index as it looks like the
  recommended / proper way to index a boolean column in which one of
  the values is searched much more than the other (todo: eventually
  check if that actually does anythnig)
- add a new cron for commits processing
- alter tests so they use this new cron (mostly by migrating them to
  `run_crons` though not solely as some still need more detailed
  management to properly check intermediate steps)

Fix an issue with closing a staged PR while at it (the "merging" tag
would potentially never be removed).
