270dfdd495 [REF] *: move most feedback messages to pseudo-templates
Current system makes it hard to iterate feedback messages and make
them clearer, this should improve things a touch.

Use a bespoke model to avoid concerns with qweb rendering
complexity (we just want GFM output and should not need logic).

Also update fwbot test setup to always configure an fwbot name, in
order to avoid ping messages closing the PRs they're talking
about, that took a while to debug, and given the old message I assume
I'd already hit it and just been too lazy to fix. This requires
updating a bunch of tests as fwbot ping are sent *to*
`fp_github_name`, but sent *from* the reference user (because that's
the key we set).

Note: noupdate on CSV files doesn't seem to work anymore, which isn't
great. But instead set tracking on the template's templates, it's not
quite as good but should be sufficient.

2009177ada [IMP] *: allow disabling staging on branch, remove fp target flag
- currently disabling staging only works globally, allow disabling on
  a single branch

  - use a toggle
  - remove a pair of tests which work specifically with `fp_target`,
    can't work with `active` (probably)
  - cleanup search of possible and active stagings, add relevant
    indexes and use direct search of relevant branches instead of
    looking up from the project

- also use toggle button for `active` on branches
- shitty workaround for upgrading DB: apparently mail really wants to
  have a `user_id` to do some weird thing, so need to re-add it after
  resetting everything

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.

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`)?

ef52785d82 [IMP] forwardport: store and display detachment reason
Currently, if a PR forward-port PR gets detached the reason for it is
not always obvious, and may have to be hunted in the logs or in
"sibling" PRs.

By writing a forward port reason (hopefully) ever time we detach a PR,
and displaying that reason in the form and dashboard, the
justification should be a lot more obvious.

2742fe18fd [FIX] forwardport: correct batching of intermediate PRs
When inserting a new branch, if there are extant forward ports
sequences spanning over the insertion, new forward ports must be
created for the new branch.

This was the case, *however* one of the cases was handled incorrectly:
PR batches (PRs to different repositories staged together) must be
forward-ported as batches. However when creating the "insert" batches,
these PRs would be split apart, leading to either inconsistent states
or an inability to merge the new forward ports (if they are
co-dependent which is a common case). This is because the handler
would look for all the relevant PRs to forward ports, but it would
fail to group them by label thereafter.

Fix that, create the `insert` batches correctly, and augment the
relevant test with an additional repository to test this case.

No gh issue was created, but this problem was reported on
odoo/odoo#110029 and odoo/enterprise#35838 (they were re-linked by
hand in the runbot and mergebot, but on github the labels remain
visibly different, one having the slug ZCwE while the other
hasO7Pr).

It's possible that the problem had occurred previously and not been
noticed (or reported), though it's also possible this issue had never
occurred before: for the latest freeze (16.1) there were 18 forward
ports spanning the insertion, but of them only 2 were the same batch.

a563fcf907 [REM] forwardport: fp_sequence field
It's almost certainly not useful, save as a minor convenience for
tests: decorrelating the branch sequence and the fp sequence seems
like it would only be extremely confusing, and on the mergebot all the
fp_sequence values are set to the default while the sequence values
are set to something useful and sensible (kinda).

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.

b45ecf08f9 [IMP] forwardport: handling of missing magic refs
Github can fail to create the magic refs on PRs
(`pull/refs/?/head`). Since forwardport relies on these refs to fetch
PR content this is an issue when it occurs, as the forward ports fail
in a loop.

After discussion with Github support, it turns out Github enabled
`allowReachableSHA1InWant` a while back, meaning it's possible to
fetch content by commit (rather than ref) as long as the content is
"in network".

Use this property as fallback when checking if we can see the PR head
before forward porting.

Also:

- remove explicit configuration of GC during fetch, it doesn't disable
  the autogc (yet?) but that's likely going to happen anyway
- update logging and logger hierarchy during forward port to make
  things clearer and easier to extract, although based on PR id rather
  than number
- rate limit failing forward ports to avoid running them on every cron
  (~ every minute), run them every ~30mn instead, this provides higher
  odds of recovery with less log garbage in case of transient github
  failure, and if the PR is stuck it limits the log pollution

32bf0deda6 [IMP] *: store filestore & forwardport checkouts in temp dirs
I'm surprised this ever worked, I guess concurrent tests stopped
working long before that? Or I misunderstood some of the historical
failures as transient?

During the cleanup of the forwardport test, I'd empty out the
`user_cache_dir('forwardport') / owner`, except the owner is always
the same (more or less) so all the tests check out their repos (and
working copies) in the same directory. If one test is cleaning up
while an other is performing a forward port, the second will blow up.

Also move the filestore to a tempdir, especially during creation of
the template db: it gets leaked so over time that generates gigabytes
of data which doesn't get cleaned up. But the template db filestore is
only "necessary" during the creation of the template, once the
template's been created it's of no use and won't be copied to create
the test dbs (though it could be, I guess).

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).

2337bd8518 [FIX] forwardport: chain crash on insert in forward-port cron
On two of the freezes, thereafter the logs showed serial crashes in
the forwardport cron when trying to find the insertion point for a new
forward-port.

The first time was not really diagnosed, the second time the cause was
found to be a retargeted PR which led to a failure of the "insertion"
forward port, which did not take that possibility in account (it
assumed -- sensibly I believed -- that an intermediate FP following a
branch insertion would always succeed, sadly the malevolent universe
had other plans).

So only insert the new forward port inside its sequence (if necessary)
if the forward port actually succeeded, otherwise ignore it.

e05cc77a57 [FIX] forwardport: don't forwardport freeze PRs
The freeze wizard has support for merging freeze / release PRs on each
of the newly created branches. But since this would be done by, well,
merging, those PRs would get forward-ported to master, and would have
to be closed there.

This creates additional work for the freeze master, and noise /
parasitic PRs.

Obviously it's possible for the freeze master to set some nonsense `up
to` (nonsense because the "real" limit doesn't exist yet at that
point), but really it never makes any sense to forward port release
PRs, so the wizard should do it.

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.

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.

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.

6b1f698c23 [IMP] forwardport: handling of updates causing conflicts on followups
If a PR is updated and has extent forward-ports, those forwardports
get updated automatically ("followup").

However there is an issue if the udpate causes a conflict in the
followup: the conflict gets silently pushed, and may fairly easily get
merged if it occurs in an area which the CI doesn't cover.

It's unclear what the policy really should be for this issue, and
there is no real way to *block* a pull request at the moment (save by
putting it in error at the mergebot level I guess?), so for now
clearly notify the user on both the modified PR and the followup,

e175609950 [IMP] forwardport: unmodified fw automatically inherit overrides
Before this change, a CI override would have to be replicated on most
/ all forward-ports of the base PR. This was intentional to see how it
would shake out, the answer being that it's rather annoying.

Also add a `statuses_full` computed field on PRs for the aggregate
status: the existing `statuses` field is just a copy of the commit
statuses which I didn't remember I kept free of the overrides so the
commit statuses could be displayed "as-is" in the backend (the
overrides are displayed separately). And while at it fix the PR
dashboard to use that new field: that was basically the intention but
then I went on to use the "wrong" field hence #433.

Mebbe the UI part should be displayed using a computed M2M (?)
as a table or as tags instead? This m2m could indicate whether the
status is an override or an "intrinsic" status.

Also removed some dead code:

* leftover from the removed tagging feature (removed the tag
  manipulation but forgot some of the setup / computations)
* unused local variables
* an empty skipped test case

5c19342bf6 [CHG] runbot_merge, forwardport: remove labelling
Because github materialises every labels change in the
timeline (interspersed with comments), the increasing labels churn
contributes to PRs being difficult to read and review.

This change removes the update of labels on PRs, instead the mergebot
will automatically send a comment to created PRs serving as a
notification that the PR was noticed & providing a link to the
mergebot's dashboard for that PR where users should be able to see the
PR state in detail in case they wonder what's what.

Lots of tests had to be edited to:

- remove any check on the labels of the PR
- add checks on the PR dashboard (to ensure that they're at least on
  the correct "view")
- add a helper to handle the comment now added to every PR by the 'bot
- since that helper is needed by both mergebot and forwardbot, the
  utils modules were unified and moved out of the odoo modules

Probably relevant note: no test was added for the dashboard
ACL, though since I had to explicitly unset the group on the repo used
for tests for things to work it looks to me like it at least excludes
people just fine.

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

Closes #327, closes #336

aa2248e379 [IMP] forwardport: close command
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.

dde59b9fe6 [IMP] runbot_merge, forwardport: better signed-off-by handling
Remove original-signed-off-by, doesn't actually seem useful given the
semantics of signed-off-by according to the kernel doc'. Plus it
didn't actually work as the intent was to keep the signoff of the
original PR in the forward-port, but that signoff is not part of the
commit we're cherrypicking (it gets added on the fly when the commit
is merged).

Therefore explicitly get the ack-chain into the PR: when merging an FP
PR, try to integrate the signoff of the original PR, that of the final
FP pr, and while at it that of the last explicit update in the commit
chain (e.g. in case there's been a conflict or something).

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.

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.

35dbfd2c12 [FIX] runbot_merge: status deduplication (maybe)
Despite the existing dedup' sometimes the "xxx failed on this
forward-port PR" would still get multiplicated due to split builds
e.g. in odoo/odoo#43935 4 such messages appear within ~5 minutes, then
one more 10mn later.

This is despite all of them having the same "build" (target_url) and
status (failure). Since the description is the only thing that's not
logged I assume that's the field which varies and makes the dedup'
fail. Therefore:

* add the description to the logging (when getting a status ping)
* exclude the description when checking if a new status should be
  taken in account or ignored: the build (and thus url) should change
  on rebuild

Hopefully fixes #281

9aac1b4a3e [ADD] forwardport: special handling of adding branches to projects
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).

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

7d79ad8d3e [FIX] forwardport: don't keep the commit date
This is not super useful and causes issues with runbot as it uses
commit dates to decide how "old" branches are, and ignores (doesn't
create when it scans them) branches more than a month old.

So the forwardport branches will be completely ignored (not considered
let alone tested) if we happen to forward-port a PR last updated more
than a month ago. Which is somewhat inconvenient.

a45f7260fa [IMP] forwardport: better handle authorship information
Before this:

* the forwardport bot always sets itself as the committer when it
  creates a forward-port branch
* when creating squashed / conflict commits, it becomes both author
  and committer

This is not great as it loses a fair amount of authorship information
and doesn't properly give credit where credit is due. Improve this in
the following ways:

* use the original authorship information as-is when forward-porting
  commits
* the the forward port fails, use the original authorship information
  as-is if there's a single commit to forward port
* otherwise if there's only a single author / committer across the
  branch being forwardported use that, if there are multiple give up
  and use the identity of the 'bot, since the branch will probably
  need to be re-done in full the authorship information of the
  placeholder commit should not matter overly much

Uses git's magic ENV variables as that's pretty much the only way to
properly override the COMMITTER date: conf items only provide for
author and committer *identity* (name and email), and while `commit`
allows overriding the *authorship* date (`--date`) it doesn't provide
any option for the *commit* date.

8e67aed792 [IMP] runbot_merge: limit spamming on PR close
When closing a PR, github completely separates the events "close the
PR" and "comment on the PR" (even when using "comment and close" in
the UI, a feature which isn't even available in the API). It doesn't
aggregate the notifications either, so users following the PR for
one reason or another get 2 notifications / mails every time a PR
gets merged, which is a lot of traffic, even more so with
forward-ported PRs multiplying the amount of PRs users are involved
in.

The comment on top of the closure itself is useful though: it allows
tracking exactly where and how the PR was merged from the PR, this
information should not be lost.

While more involved than a simple comment, *deployments* seem like
a suitable solution: they allow providing links as permanent
information / metadata on the PRs, and apparently don't trigger
notifications to users.

Therefore, modify the "close" method so it doesn't do
"comment-and-close", and provide a way to close PRs with non-comment
feedback: when the feedback's message is structured (parsable as
json) assume it's intended as deployment-bound notifications.

TODO: maybe add more keys to the feedback event payload, though in my
      tests (odoo/runbot#222) none of the deployment metadata
      outside of "environment" and "target_url" is listed on the PR
      UI

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).

37cf6accb7 [FIX] forwardport: FP PR getting CI'd after initial FP check
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.

However this turns out to have a huge issue in the presence of renamed

much undesirable.

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.
