Also reduce the grace period for merged PR branches to 1 week (from
2), and go through the on-disk repository instead of the github API.
Technically it might even be possible to do this un bulk, though that
seems annoying in case of failure (e.g. because somebody else deleted
the branch previously).
Fixes#1082
For historical reasons pretty much all tests used to use the contexts
legal/cla and ci/runbot. While there are a few tests where we need the
interactions of multiple contexts and that makes sense, on the vast
majority of tests that's just extra traffic and noise in the
test (from needing to send multiple statuses unnecessarily).
In fact on the average PR where everything passes by default we could
even remove the required statuses entirely...
Should limit the risk of cases where the fork contains outdated
versions of the reference branches and we end up with odd outdated /
not up to date basis for branches & updates, which can lead to
confusing situations.
- only remind weekly initially (not daily)
- root reminders on the forward port's creation, not the source's
merge date
- cap reminder interval at 4 weeks (instead of doubling every time)
- track reminders on forward ports, don't share between siblings
- remove `forwardport_updated_before` from the testing system, it's
now possible to just update `reminder_next` to a past date and see
if it gets triggered (it should to nothing on sources, or on forward
port in a state which does not warrant concern)
Fixes#801
The `to_pr` helper was added a *while* ago to replace the pretty
verbose process of looking a PR with the right number in the right
repository after a `make_pr`. However while I did some ad-hoc
replacement of existing `search` calls as I had to work with existing
tests I never did a full search and replace to try and excise searches
from the test suite.
This is now done. I've undoubtedly missed a few, but a hundred-odd
lines of codes have been simplified.
Reminding users that `r-` on a forward port only unreviews *that*
forwardport is useful, as `r+;r-` is not a no-op (all preceding
siblings are still reviewed).
However it is useless if all siblings are not approved or already
merged. So avoid sending the warning in that case.
Fixes#934
The FW reminder is useful to remind people of the outstanding forward
ports they need to process, as taking too long can be an issue.
They are, however, not useful if the developer has already done
everything, the PR is ready and unblocked, but the mergebot has fallen
behind and has a hard time catching up. In that case there is nothing
for the developer to do, so pinging them is not productive, it's only
frustrating.
Fixes#930
In some cases, feedback to the PR author that an r+ is redundant went
missing.
This turns out to be due to the convolution of the handling of
approval on forward-port, and the fact that the target PR is treated
exactly like its ancestors: if the PR is already approved the approval
is not even attempted (and so no feedback if it's incorrect).
Straighten up this bit and add a special case for the PR being
commented on, it should have the usual feedback if in error or already
commented on.
Furthermore, update `PullRequests._pr_acl` to kinda work out of the
box for forward-port: if the current PR is a forward port,
`is_reviewer` should check delegation on all ancestors, there doesn't
seem to be any reason to split "source_reviewer", "parent_reviewer",
and "is_reviewer".
Fixes#939
These are pretty simple to convert as they are straightforward: an
item is added to a work queue (table), then a cron regularly scans
through the table executing the items and deleting them.
That means the cron trigger can just be added on `create` and things
should work out fine.
There's just two wrinkles in the port_forward cron:
- It can be requeued in the future, so needs a conditional trigger-ing
in `write`.
- It is disabled during freeze (maybe something to change), as a
result triggers don't enqueue at all, so we need to immediately
trigger after freeze to force the cron re-enabling it.
Apparently I'd already fixed that in
286c1fdaee but it has yet to be
deployed.
While at it, add a feedback message to clarify that, unlike `r+`, `r-`
on forward ports does *not* propagate.
Fixes#912
98aaa910 updated the forwardport notifications system to notify on the
forward ports rather than the source, to try and mitigate or at least
shift some of the spam: spam the followers of the original
source (which might be many people) somewhat less, at the possible
cost of spamming the author and reviewer more because they get a
message per forgotten forward port.
This change aims to alleviate part of the latter, by only notifying on
PRs which actually need to be r+'d, and not notifying on those which
will implicitly "inherit" the reviews. This should cut down on
redundant notifications and let users focus on the important ones.
Currently webhook secrets are configured per *project* which is an
issue both because different repositories may have different
administrators and thus creates safety concerns, and because multiple
repositories can feed into different projects (e.g. on mergebot,
odoo-dev/odoo is both an ancillary repository to the main RD project,
and the main repository to the minor / legacy master-wowl
project). This means it can be necessary to have multiple projects
share the same secret as well, this then mandates the secret for more
repositories per (1).
This is a pain in the ass, so just detach secrets from projects and
link them *only* to repositories, it's cleaner and easier to manage
and set up progressively.
This requires a lot of changes to the tests, as they all need to
correctly configure the signaling.
For `runbot_merge` there was *some* setup sharing already via the
module-level `repo` fixtures`, those were merged into a conftest-level
fixture which could handle the signaling setup. A few tests which
unnecessarily set up repositories ad-hoc were also moved to the
fixture. But for most of the ad-hoc setup in `runbot_merge`, as well
as `forwardport` where it's all ad-hoc, events sources setup was just
appended as is. This should probably be cleaned up at one point, with
the various requirements collected and organised into a small set of
fixtures doing the job more uniformly.
Fixes#887
Using a regex as the pattern is quite frustrating due to all the
escaping necessary, which in this refactoring I found out I'd missed,
multiple times.
Convert the pattern to something bespoke but not too complicated, we
may want to add anchoring support and a bit more finesse and the
future but for now straightforward "holes" seem to work well. I've
added support for capturing and even named groups even if this as yet
unnecessary and unused.
Fixes#861

I have been convinced that this might be an improvement to the affairs
of the people: originally the message was sent to the source PR so we
wouldn't have to ping the author & reviewer and to limit the amount of
spam, *however*:
- we ended up adding pings anyway
- it also pings the followers of the source PR
- it increases the size of the original discussion (especially if was
- originally long)
- it adds steps to fixing the issue as you need to bounce from the
source to the forward ports
Note that this might still notify a lot of people as they might be
made followers of the forward ports automatically, and it increases
the messaging load of the forwardbot significantly. But we'll see how
things go. Worst case scenario, we can revert it back.
Fixes#836
Thank god I have a bunch of tests because once again I forgot / missed
a bunch of edge cases in doing the conversion, which the tests
caught (sadly that means I almost certainly broke a few untested edge
cases).
Important notes:
Handling of parent links
------------------------
Unlike PRs, batches don't lose their parent info ever, the link is
permanent, which is convenient to trawl through a forward port
(currently implemented very inefficiently, maybe we'll optimise that
in the future).
However this means the batch having a parent and the batch's PRs
having parents are slightly different informations, one of the edge
cases I missed is that of conflicting PRs, which are deparented and
have to be merged by hand before being forward ported further, I had
originally replaced the checks on a pr and its sibling having parents
by just the batch.
Batches & targets
-----------------
Batches were originally concepted as being fixed to a target and PRs
having that target, a PR being retargeted would move it from one batch
to an other.
As it turns out this does not work in the case where people retarget
forward-port PRs, which I know they do because #551
(2337bd8518). I could not think of a
good way to handle this issue as is, so scrapped the moving PRs thing,
instead one of the coherence checks of a batch being ready is that all
its PRs have the same target, and a batch only has a target if all its
PRs have the same target.
It's possible for somewhat odd effects to arise, notably if a PR is
closed (removed from batch), the other PRs are retargeted, and the new
PR is reopened, it will now be on a separate batch even if it also
gets retargeted. This is weird. I don't quite know how I should handle
it, maybe batches could merge if they have the same target and label?
however batches don't currently have a label so...
Improve limits
--------------
Keep limits on the PRs rather than lift them on the batchL if we can
add/remove PRs of batches having different limits on different PRs of
the same batch is reasonable.
Also leave limit unset by default: previously, the limit was eagerly
set to the tip (accessible) branch. That doesn't really seem
necessary, so stop doing that.
Also remove completely unnecessary `max` when trying to find a PR's
next target: `root` is either `self` or `self.source_id`, so it should
not be possible for that to have a later target.
And for now ensure the limits are consistent per batch: a PR defaults
to the limit of their batch-mate if they don't have one, and if a
limit is set via command it's set on all PRs of a batch.
This commit does not allow differential limits via commands, they are
allowed via the backend but not really tested. The issue is mostly
that it's not clear what the UX should look like to have clear and not
super error prone interactions. So punt on it for now, and hopefully
there's no hole I missed which will create inconsistent batches.
This commit revisits the commands set in order to make it more
regular, and limit inconsistent command-sets, although it includes
pseudo-command aliases for common tasks now removed from the core set.
Hard Errors
===========
The previous iteration of the commands set would ignore any
non-command term in a command line. This has been changed to hard
error (and ignoring the entire thing) if any command is unknown or
invalid.
This fixes inconsistent / unexpected interpretations where a user
sends a command, then writes a novel on the same line some words of
which happen to *also* be commands, leading to merge states they did
not expect. They should now be told to fuck off.
Priority Restructuring
----------------------
The numerical priority system was pretty messy in that it confused
"staging priority" (in ways which were not entirely straightforward)
with overrides to other concerns.
This has now being split along all the axis, with separate command
subsets for:
- staging prioritisation, now separated between `default`, `priority`,
and `alone`,
- `default` means PRs are picked by an unspecified order when
creating a staging, if nothing better is available
- `priority` means PRs are picked first when staging, however if
`priority` PRs don't fill the staging the rest will be filled with
`default`, this mode did not previously exist
- `alone` means the PRs are picked first, before splits, and only
`alone` PRs can be part of the staging (which usually matches the
modename)
- `skipchecks` overrides both statuses and approval checks, for the
batch, something previously implied in `p=0`, but now
independent. Setting `skipchecks` basically makes the entire batch
`ready`.
For consistency this also sets the reviewer implicitly: since
skipchecks overrides both statuses *and approval*, whoever enables
this mode is essentially the reviewer.
- `cancel` cancels any ongoing staging when the marked PR becomes
ready again, previously this was also implied (in a more restricted
form) by setting `p=0`
FWBot removal
=============
While the "forwardport bot" still exists as an API level (to segregate
access rights between tokens) it has been removed as an interaction
point, as part of the modules merge plan. As a result,
fwbot stops responding
----------------------
Feedback messages are now always sent by the mergebot, the
forward-porting bot should not send any message or notification
anymore.
commands moved to the merge bot
-------------------------------
- `ignore`/`up to` simply changes bot
- `close` as well
- `skipci` is now a choice / flag of an `fw` command, which denotes
the forward-port policy,
- `fw=default` is the old `ci` and resets the policy to default,
that is wait for the PR to be merged to create forward ports, and
for the required statuses on each forward port to be received
before creating the next
- `fw=skipci` is the old `skipci`, it waits for the merge of the
base PR but then creates all the forward ports immediately (unless
it gets a conflict)
- `fw=skipmerge` immediately creates all the forward ports, without
even waiting for the PR to be merged
This is a completely new mode, and may be rather broken as until
now the 'bot has always assumed the source PR had been merged.
approval rework
---------------
Because of the previous section, there is no distinguishing feature
between `mergebot r+` = "merge this PR" and `forwardbot r+` = "merge
this PR and all its parent with different access rights".
As a result, the two have been merged under a single `mergebot r+`
with heuristics attempting to provide the best experience:
- if approving a non-forward port, the behavior does not change
- else, with review rights on the source, all ancestors are approved
- else, as author of the original, approves all ancestors which descend
from a merged PR
- else, approves all ancestors up to and including the oldest ancestor
to which we have review rights
Most notably, the source's author is not delegated on the source or
any of its descendants anymore. This might need to be revisited if it
provides too restrictive.
For the very specialized need of approving a forward-port *and none of
its ancestors*, `review=` can now take a comma (`,`) separated list of
pull request numbers (github numbers, not mergebot ids).
Computed State
==============
The `state` field of pull requests is now computed. Hopefully this
makes the status more consistent and predictable in the long run, and
importantly makes status management more reliable (because reference
datum get updated naturally flowing to the state).
For now however it makes things more complicated as some of the states
have to be separately signaled or updated:
- `closed` and `error` are now separate flags
- `merge_date` is pulled down from forwardport and becomes the
transition signal for ready -> merged
- `reviewed_by` becomes the transition signal for approval (might be a
good idea to rename it...)
- `status` is computed from the head's statuses and overrides, and
*that* becomes the validation state
Ideally, batch-level flags like `skipchecks` should be on, well, the
batch, and `state` should have a dependency on the batch. However
currently the batch is not a durable / permanent member of the system,
so it's a PR-level flag and a messy pile.
On notable change is that *forcing* the state to `ready` now does that
but also sets the reviewer, `skipchecks`, and overrides to ensure the
API-mediated readying does not get rolled back by e.g. the runbot
sending a status.
This is useful for a few types of automated / programmatic PRs
e.g. translation exports, where we set the state programmatically to
limit noise.
recursive dependency hack
-------------------------
Given a sequence of PRs with an override of the source, if one of the
PRs is updated its descendants should not have the override
anymore. However if the updated PR gets overridden, its descendants
should have *that* override.
This requires some unholy manipulations via an override of `modified`,
as the ORM supports recursive fields but not recursive
dependencies (on a different field).
unconditional followup scheduling
---------------------------------
Previously scheduling forward-port followup was contigent on the FW
policy, but it's not actually correct if the new PR is *immediately*
validated (which can happen now that the field is computed, if there
are no required statuses *or* all of the required statuses are
overridden by an ancestor) as nothing will trigger the state change
and thus scheduling of the fp followup.
The followup function checks all the properties of the batch to port,
so this should not result on incorrect ports. Although it's a bit more
expensive, and will lead to more spam.
Previously this would not happen because on creation of a PR the
validation task (commit -> PR) would still have to execute.
Misc Changes
============
- If a PR is marked as overriding / canceling stagings, it now does
so on retry not just when setting initially.
This was not handled at all previously, so a PR in P0 going into
error due to e.g. a non-deterministic bug would be retried and still
p=0, but a current staging would not get cancelled. Same when a PR
in p=0 goes into error because something was failed, then is updated
with a fix.
- Add tracking to a bunch of relevant PR fields.
Post-mortem analysis currently generally requires going through the
text logs to see what happened, which is annoying.
There is a nondeterminism / inconsistency in the tracking which
sometimes leads the admin user to trigger tracking before the bot
does, leading to the staging tracking being attributed to them
during tests, shove under the carpet by ignoring the user to whom
that tracking is attributed.
When multiple users update tracked fields in the same transaction
all the changes are attributed to the first one having triggered
tracking (?), I couldn't find why the admin sometimes takes over.
- added and leveraged support for enum-backed selection fields
- moved variuous fields from forwardport to runbot_merge
- fix a migration which had never worked and which never run (because
I forgot to bump the version on the module)
- remove some unnecessary intermediate de/serialisation
fixes#673, fixes#309, fixes#792, fixes#846 (probably)
Continuation of 327500bc83 for an other
edge case of closing a PR to a detached branch with a merged
descendant. The mergebot would:
- warn on the parent about it being detached due to being closed
- then warn on the child about it being detached due to the parent
being closed (despite it being merged already)
- then warn the parent *again* due to the child being detached
At least some of those messages were still produced by the test case,
stop them.
Issue was noticed on odoo/odoo#145969 and odoo/odoo#145984 due to 16.2
being deactivated.
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.
Fixes#769
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.
Fixes#679
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).
Fixes#584
- avoid pinging the author of the fw PR (which is the forward-bot
itself)
- instead ping the author and reviewer of the source, and possibly the
reviewer of the PR if any
- might also be a good idea to ping reviewers of intermediate PRs?
- trying to r+ a detached PR *via the forwardbot* should warn, same as
a non-forwardport PR
- the following sibling of a closed PR should be detached from
it (probably)
- when a closed forward-port PR is reopened, there should be a
notification that it is detached and merged via mergebot
Fixes#617
Old messages were quite inconsistent in their pinging of the PR author
and reviewer.
Reviewed messages (probably missed some but...) and try to more
consistently ping when the feedback requires some sort of action in
order to proceed.
Fixes#592
The forward-port process currently automatically adds delegates of a
PR as delegates on its forward ports, but that only works for
the *source* pull request.
If a delegate is added to a forward-port, they were not able to
approve the followups to that initial port, which makes little sense.
Fixes#548
When using the forwardport's shortcut, the bot would not skip
already-approved PRs leading to a warning from the mergebot that the
PR was already approved (out of nowhere which was weird).
During the walk to the ancestors, skip any PR which is not
approvable (either already approved or in a state where that makes no
sense e.g. closed).
Fixes#543
If a reviewer doesn't have an email set, the Signed-Off-By is an
`@users.noreply.github.com` address which just looks weird in the
final result.
Initially the thinking was that emails would be required for users to
*be* reviewers or self-reviewers, but since those are now o2ms / m2ms
it's a bit of a pain in the ass.
Instead, provide an action to easily try and fetch the public email of
a user from github.
Fixes#531
* 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~~
Fixes#500
"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.
Fixes#509
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.
Fixes#482
a45f7260fa had intended to use the
original authorship information for conflict commit even if there were
multiple commits, as long as there was only one author (/ committer)
for the entire sequence.
Sadly the deduplication was buggy as it took the *authorship date* in
account, which basically ensured commits would never be considered as
having the same authorship outside of tests (where it was possible for
commits to be created at the same second).
Related to #505
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
Fixes#439.
Fixes#433.
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.
Fixes#419
2.29 changed the formatting of conflict labels (the stuff added at the
end of the closing conflict marker):
6cceea19eb
Used to be
>>>>>>> <commit>... <text>
now is
>>>>>>> <commit> (<text>)
Just ignore everything after the commit hash.
The exponential backoff offsets from the write_date of the children
PRs, however it doesn't reset, so the offsetting gets bumped up way
more than originally expected or designed if the child PRs are under
active development for some reason.
Fix this by adding a field to specifically record the date of merge of
a PR, and check that feature against the backoff offset. This should
provide more regular and reliable backoff.
Fixes#369
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
Closes#327, closes#336
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).
Fixes#284
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.
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
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.
Closes#274
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.
Fixes#255
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
Fixes#224
If a PR is *merged*, enqueue it for deletion (with a 2 weeks delay).
Mainly to avoid FW branches staying around long after they've been
merged (possibly eventually closed?), will also clean up regular
merged branches, including historical merges forgotten by their
author.
Fixes#230
* add a sorted method on fake models
* fix recordset equality to ignore ids order
* when creating commits on a ref, add a param to only *update* the ref
(forcefully): when simulating a force-push we don't want to *create*
a ref as that might silently be done in the wrong repository entirely
* fix pytest.skip call at the module level, not sure where it came
from and why I missed it until now
