2ad188201b [IMP] runbot_merge: speedup frontend page
The mergebot page become a bit slow with the years, it is time to make
small optimisation to speed up thinks a little.

Note: all changes where applied modifying the views or adding index by
hand. There is still room for improvement but it would need more in
depth refactoring, mainly adding specialized computed fields to
enable a better batching.

The first issue was using branch.staging_ids

    branch.staging_ids.sorted(lambda s: s.staged_at, reverse=True)[:6]

The number of staging_ids is increasing and prefetching + sorting all
of them is slow.

The proposed solution is to replace it by a search, not ideal, a
specialized compute field may be a good idea, but this is a quick fix
that can be done editing a view.

    branch.env['runbot_merge.stagings'].search([('target', '=', branch.id)],order='staged_at desc', limit=6)

Other changes are just index on critical columns.

Before changes, /runbot_merge page takes ~5s to load
After changes,  /runbot_merge page takes ~1s to load

Small note: note 100% sure that runbot_merge.batch.target was useful

23e1b93465 [FIX] runbot_merge: a few issues with updated staging check
1cea247e6c tried to improve staging
checks to avoid staging PRs in the wrong state, however it had two
issues:

PR state
--------

The process would reset the PR's state to open, but unless the head
was being resync'd it wouldn't re-apply the statuses on the state,
leading to a PR with all-valid statuses, but a missing CI.

Message
-------

The message check didn't compose the PR message the same way PR
creation / update did (it did not trim the title and description
individually, only after concatenation), resulting in a
not-actually-existing divergence getting signaled in the case where
the PR title ends or the description starts with whitespace.

Expand relevant test, add a utility function to compose a PR message
and use it everywhere for coherence.

Also update the logging and reporting to show a diff of all the
updated items (hidden behind a `details` element).

907c6072d1 [FIX] runbot_merge: cancel master staging on freeze
If there are bump PRs anyway: the bump commits will cause the
forward-port of the staging to fail, so might as well clearly notify
everybody of the issue if there is a pending staging, and not waste
too much time waiting for a staging which can not succeed.

We could also cancel stagings when there's no bump PR, but it's not
clear that there's any reason to do so: if we didn't touch any master
branch, there's no reason for the staging to fail, or to otherwise
cancel it.

And obviously we can't have staged anything on the new branch so
there's nothing to cancel.

8d7d6302d3 [FIX] runbot_merge: make freeze wizard labels lookup not shit
I DECLARE BANKRUPTCY!!!

The previous implementation of labels lookup was really not
intuitive (it was just a char field, and matched labels by equality
including the owner tag), and was also full of broken edge
cases (e.g. traceback if a label matched multiple PRs in the same repo
because people reuse branch names).

Tried messing about with contextual `display_name` and `name_search`
on PRs but the client goes wonky in that case, and there is no clean
autocomplete for non-relational fields.

So created a view which reifies labels, and that can be used as the
basis for our search. It doesn't have to be maintained by hand, can be
searched somewhat flexibly, we can add new view fields in the future
if desirable, and it seems to work fine providing a nice
understandable UX, with the reliability of using a normal Odoo model
the normal way.

Also fixed the handling of bump PRs, clearly clearing the entire field
before trying to update existing records (even with a link_to
inbetween) is not the web client's fancy, re-selecting the current
label would just empty the thing entirely.

So use a two-step process slightly closer to the release PRs instead:

- first update or delete the existing bump PRs
- then add the new ones

The second part is because bump PRs are somewhat less critical than
release, so it can be a bit more DWIM compared to the more deliberate
process of release PRs where first the list of repositories involved
has to be set up just so, then the PRs can be filled in each of them.

ae53c87fc9 [FIX] runbot_merge: allow adding and removing release PR lines
In order to support partial freezing, we need the ability to remove
some of the release lines for the repos we don't want to
freeze (e.g. because they don't use per-version branches).

This subsequently means we need the ability to *create* new lines if
we fucked up and removed one we should not have. Alternatively the
freeze meat-bot could cancel the entire thing and redo the wizard but
that seems harsh and mean, so don't do that.

Fixes 0f3647b7c7 which specifically
mentioned partial freeze then proceeded to make them entirely
impossible anyway.

1cea247e6c [FIX] runbot_merge: sync PR target and message on check
Previously the mergebot would only sync the head commit, but synching
more is useful.

Also update the final sanity check on staging:

- as with check, update the message & target branch
- reset PR state and post a message when updating message instead of
  doing so silently

Note: maybe only fail the staging if the message is updated *and*
relevant to staging (aka there's a merge method and it's not
`rebase`)?

2746a13163 [FIX] runbot_merge: multi-commit squashing
If commits have different authors (/ committers), the mergebot would
ask github to create a commit with an author (/ committer) of `None` /
`null`.

Apparently github really does not like that, and complains that

> nil is not an object

So remove the key entirely. Also fix the collision between `author`
and the `Co-Authored-By` list, which could lead to trying to set an
`author` of `[name, email]` instead of an object, which is also not
accepted by github.

0f3647b7c7 [FIX] *: freeze wizard take 3
Fixes to the new bits which didn't really work:

- Fix borked view layout
- Add some help to the label fields
- Improve the resolution of label -> pr, and fix
- Also make the feature actually work for bump PRs
- Also make pr -> label work more reliably, now allows setting one PR
  and getting the other PRs of the same batch (with the same label)
  even without setting the label by hand

An autocomplete for the label has been considered but there is no
autocomplete field for char/selection fields, and it seems way too
much work for the utility:

- either create a brand new widget for 15.0 which will have to be
  entirely rewritten in 16
- or create a transient model composed entirely of fake records to
  provide an m2o to records which don't actually exist as label
  bearers, which is also a lot of unnecessary work

NOTE: we want to support partial freezing (aka not freeze all the
      branches because some of them have different release models
      than others), so some project repos *not* having a release
      PR is fine and normal, such a validation should not be added.

7948e59c51 [FIX] *: fix forward port inserter if last branch is disabled
In case where the last branch (before the branch being frozen) is
disabled, the forwardport inserter screws up, and fails to correctly
create the intermediate forwardports from the new branch.

Also when disabling a branch, if there are FW PRs which target that
branch and have not been forward-ported further, automatically
forward-port them as if the branch had been disabled when they were
created, this should limit data loss and confusion.

Also change the message set on PRs when disabling a branch: because of
user conflicts in test setup, the message about a branch being
disabled would close the PRs, which would then orphan the followup,
leading to unexpected / inconsistent behaviour.

985aaa5798 [FIX] runbot_merge: lock-in statuses after a staging has finished
The `statuses` field of a staging is always "live" because it's a
computed non-stored field. This is an issue when a staging finishes in
whatever state, then someone gets new statuses sent on one of the head
commits, either by rebuilding (part of) the staging or by just using
the same commit for one of their branches.

This makes the reporting of the main dashboard confusing, as one might
look at a failed staging and see all the required statuses
successful. It also makes post-mortem analysis more complicated as the
logs have to be trawled for what the statuses used to be (and they
don't always tell).

Solve this by storing a snapshot of the statuses the first time a
staging moves away from `pending`, whether it's to success or failure.

0c882fc0df [IMP] runbot_merge: automation around branch deactivation

- surface the state of the branch in the PR dashboard (also surface

- close & notify every PR to a branch being deactivated
- cancel any current staging to the branch (as a consequence of the
  above)

b86092de83 [IMP] *: freeze wizard v3, freezer and wizarder
Stop *staging* release PRs: they are normally fairly simple and should
not fail their staging outside of unreliable tests (or possibly a few
edge cases e.g. forgot one version change thing), however staging them
creates the possibility of a "version hole" on the release branch
which is undesirable.

Instead, immediately and unconditionally push the release commits onto
the newly created branches, if there are things which don't work they
can be fixed afterwards (and the process refined, maybe).

Also add the same feature for *bump* PRs, with the difference that the
bump PRs are not created / requested by default (they have to be opted
in individually).

For convenience, add a feature which automatically finds the PRs via
inputting the label (not really tested yet).

2898c7edd4 [FIX] runbot_merge: updating of commit date on rebase
On #509, the rebasing process was changed to forcefully update the
commit date of the commits, in order to force trigger builds.

However when squashing was re-enabled for #539 for some fool reason it
implemented its own bespoke rebasing (despite that not actually saving
any API call that I can see), meaning it did *not* update the commit
date. As such, an old commit being squashed would not get picked up by
the runbot, which is what happened to odoo/documentation#1226 (which
ultimately had to be hand-rebased after some confusion as to why it
did not work).

Update `_stage_squash` to go through `rebase` the normal way, also
update `rebase` to pop the commit date entirely instead of setting it
manually, and update the squashing test to check that the commit date
gets properly updated.

1add3d4854 [FIX] runbot_merge: freeze being triggered upon reopening the wizard
The freeze wizard was implemented using a single action to open and
validate the dialog.

This was a mistake, as it means if there are no errors left (e.g. all
the PRs being waited for are now validated) trying to view the freeze
wizard will immediately validate it and commit the freeze, which is
unexpected, surprising, and unsafe e.g.

- open wizard
- add freeze prs
- add a required pr or two
- close and go do something else
- be told that more PRs need to be waited for
- reopen wizard
- oops freeze is done

So split the "open action" part of `action_freeze` into opening the
action and performing the freeze. The "freeze" / "view freeze" button
on the project only activates the latter, and the actual freeze
operation is only triggered from the wizard's "Freeze" button.

4da0f5df69 [ADD] runbot_merge: ~~tree~~ freeze wizard
Provides a less manual interface for creating the freeze:

* takes the name of the branch to create
* takes any number of PRs which must be part of the freeze
* takes PRs representing the HEADs of the new branches

Then essentially takes care of the test.

Implementation of the actual wizard is not trivial but fairly
straightforward and linear, biggest issue is not being able to
`project_id.branch_ids[1]` to get the new branch, not sure why but it
seems to ignore the ordering, clearing the cache doens't fix it.

When creating the branches, add a sleep after each one for secondary
rate limiting purposes. Same when deleting branches.

Also the forwardbot has been updated to disable the forwardport cron
while a freeze is ongoing, this simplifies the freezing process.

Note: after recommendation of @aab-odoo, tried using `_applyChanges`
in `_checkState` but it simply did not work: the two relational fields
got completely frozen and were impossible to update, which is less
than ideal. Oh well, hopefully it works well enough like this for now.

bce0836aa9 [FIX] runbot_merge: avoid editing title line of commits
When a commit is lacking the purpose (?) tag e.g. `[FIX]`, `[IMP]`,
..., a normal commit message of the form `<module>: <info>` marches
the looks of a git pseudo-header.

This results in a commit rewrite rejiggering the entire thing and
breaking the message by moving the title to the pseudo-headers and
mis-promoting either the `closes` line of body content to "title",
resulting in a really crappy commit message
e.g. odoo/odoo@d4aa9ad031.

line, and re-inject it without processing in the output.

To make the logs less weird, always log a staging failure even when it

bf34e9aa95 [FIX] runbot_merge: ensure PR description is correct on merge
Because sometimes github updates are missed (usually because github
never triggers it), it's possible for the mergebot's view of a PR
description to be incorrect. In that case, the PR may get merged with
the wrong merge message entirely, through no fault of the user.

Since we already fetch the PR info when staging it, there's very
little overhead to checking that the PR message we store is correct
then, and update it if it's not. This means the forward-port's
description should also be correct.

While at it, clean the forward port PR's creation a bit:

- there should always be a message since the title is required on
  PRs (only the body can be missing), therefore no need to check that
- as we're adding a bunch of pseudo-headers, there always is a body,
  no need for the condition
- inline the `pr_data` and `URL`: they were extracted for the support
  of draft PRs, since that's been removed it's now unnecessary

bef6a8e2d0 [FIX] runbot_merge: point to the right status on staging failure
On staging failure, the 'bot would point to the first error or failure
status it found on the commit. This turns out not to be correct as
we (now) have various statuses which are optional, and may fail
without blocking stagings (either because they're solely informational
or because they're blocking & overridable on PRs).

Fix this so the 'bot points to the first *required* failure.

82174ae66e [IMP] *: add draft support to mergebot, kinda
* Remove the forwardport creating PRs in draft, that was mostly to
  avoid codeowners triggering but we've removed the github one and
  hand-rolled it, so not a concern anymore.
* Prevent merging `draft` PRs, the mergebot rejects approval on draft
  PRs and insults people.

TBD (maybe): try to create *conflicting* forward-port PRs in draft so
it's clearer they need to be *fixed*? Issue of not being able to do
that on all private repositories remains so~~

4b12d88b3e [IMP] runbot_merge: remove unnecessary uniquifier dummy commits
"Uniquifier" commits were introduced to ensure branches of a staging
on which nothing had been staged would still be rebuilt properly.

This means technically the branches on which something had been
staged never *needed* a uniquifier, strictly speaking. And those lead
to extra building, because once the actually staged PRs get pushed
from staging to their final destination it's an unknown commit to the
runbot, which needs to rebuild it instead of being able to just use
the staging it already has.

Thus only add the uniquifier where it *might* be necessary:
technically the runbot should not manage this use case much better,
however there are still issues like an ancillary build working with
the same branch tip (e.g. the "current master") and sending a failure
result which would fail the entire staging. The uniquifier guards
against this issue.

Also update rebase semantics to always update the *commit date* of the
rebased commits: this ensures the tip commit is always "recent" in the
case of a rebase-ff (which is common as that's what single-commit PRs
do), as the runbot may skip commits it considers "old".

Also update some of the utility methods around repos / commits to be
simpler, and avoid assuming the result is JSON-decodable (sometimes it
is not).

Also update the handling of commit statuses using postgres' ON
CONFLICT and jsonb support, hopefully this improves (or even fixes)
the serialization errors. Should be compatible with 9.5 onwards which
is *ancient* at this point.

6096cc61a9 [IMP] *: tag all rebased commits with source PRev
Although it's possible to find what PR a commit was part of with a bit
of `git log` magic (e.g. `--ancestry-path COMMIT.. --reverse`) it's
not the most convenient, and many people don't know about it, leading
them to various debatable decisions to try and mitigate the issue,
such as tagging every commit in a PR with the PR's identity, which
then leads github to spam the PR itself with pingbacks from its own
commits. Which is great.

Add this information to the commits when rebasing them (and *only*
when rebasing them), using a `Part-of:` pseudo-header.

30cfc4fe59 [IMP] runbot_merge: disable active test on batch fields
For post-mortem investigations and manipulations, they're inconvenient
as the batches are deactivated on success and failure.

f6aff3e71c [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
