If the stagings are going to be created locally (via a git working
copy rather than the github API), the mergebot part needs to have
access to the cache, so move the cache over. Also move the maintenance
cron.
In an extermely minor way, this prefigures the (hopeful) eventual
merging of the ~~planes~~ modules.
In 81ce4ea02b the delta for PRs being
listed in the `/forwardport/outstanding` page was increased from 3
days to 7 (1 week), however the warning box in the home page still
used the old cutoffs leading to
An inconsistency between the two and an effective severe overcounting,
as the reason why the cutoff was increased to a week is forward ports
can take a while or the author / reviewer can be a touch busy at end
of week, so 3~4 days are routine when a PR is merged on thursday or
friday (and even worse if there's bank holidays in the mix).
Fix outstanding query to make a positive `state` filtering, instead of
negative, matching 3b52b1aace8674259812a76b1566260937dbcacb.
Also manually create a map of stagings (grouped by branch) sharing a
single prefetch set.
For odoo the mergebot home page has 12 branches in the odoo project
and 8 in spreadsheet, 6 stagings each. This means 120 queries to
retrieve all the heads (Odoo stagings have 5 heads and spreadsheet
have 1, but that seems immaterial).
By fixing `_compute_statuses` and creating a single prefetch set for
all stagings of all branches we can fetch all the commits in a single
query instead of 120.
- add support for authorship (not just approval)
- make display counts directly
- fix `state` filter: postgres can't do negative index lookups
- add indexes for author and reviewed_by as we look them up
- ensure we handle the entire source filtering via a single subquery
Closes#778
- 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
Fixes#727
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
The current system makes / lets GC run during fetching. This has a few
issues:
- the autogc consumes resources during the forward-porting
process (not that it's hugely urgent but it seems unnecessary)
- the autogc commonly fails due to the combination of large repository
(odoo/odoo) and low memory limits (hardmem for odoo, which get
translated into soft ulimits)
As a result, the garbage collection of the repository sometimes stops
entirely, leading to an increase in repository size and a decrease in
performances.
To mitigate this issue, disable the automagic gc and maintenance
during normal operation, and instead add a weekly cron which runs an
aggressive GC with memory limits disabled (as far as they can get, if
the limits are imposed externally there's nothing to be done).
The maintenance is implemented using a full lockout of the
forward-port cron and an in-place GC rather than a copy/gc/swap, as
doing this maintenance at the small hours of the week-end (sat-sun
night) seems like a non-issue: currently an aggressive GC of odoo/odoo
(using the default aggressive options) takes a total of 2:30 wallclock
(5h user) on a fairly elderly machine (it's closer to 20mn wallclock
and 2h user on my local machine, also turns out the cache repos are
kinda badly configured leading to ~30% more objects than necessary
which doesn't help).
For the record, a fresh checkout of odoo/odoo right now yields:
| Overall repository size | |
| * Commits | |
| * Count | 199 k |
| * Total size | 102 MiB |
| * Trees | |
| * Count | 1.60 M |
| * Total size | 2.67 GiB |
| * Total tree entries | 74.1 M |
| * Blobs | |
| * Count | 1.69 M |
| * Total size | 72.4 GiB |
If this still proves insufficient, a further option would be to deploy
a "generational repacking" strategy:
https://gitlab.com/gitlab-org/gitaly/-/issues/2861 (though apparently
it's not yet been implemented / deployed on gitlab so...).
But for now we'll see how it shakes out.
Close#489
It's likely that the PR pages are seen more commonly than the
dashboard by most users, so add alerts there in case users wonder
what's happening.
Fixes#580
This is an important bit of information but it was not visible without
going into the backend.
`user-select-none` doesn't work in BS3 but that way it'll be ready for
an eventual update. Currently when hovering the badge the cursor
switches to text selection, and the text is selectable, which is
useless.
Complements 4e235a2 and finishes the fixes for #617
- code in the various menus added over time through the UI (queues,
configuration, ...)
- update / improve PR layout a tick
- fix "outstanding forward ports" count on the dashboard
- improve hover title / help on dashboard
- add date of last modification (usually date of success / failure)
- make casing more coherent (everything lowercase)
- add explicit note that UTC date on staged at label is staged at datetime
- rediscover yet again that the staging information is when hovering
on the staging *except the staged at label*
- improve `PullRequest.unstage` to always insert the PR at the start of the
reason when cancelling the staging, for clarity / traceability
Closes#560, closes#609
* Adds a changelog page, linked from the main, with content
automatically loaded from the source. To avoid conflicts, each entry
is its own file and entries are grouped by the month during which
the update will (probably) be deployed
* The last group (most likely "last update") doesn't have a title, the
rest do.
* Add changelog entries from the last update so it's not too empty.
* Also update the layout for the alerts a bit: remove bottom margin to
reduce loss of whitespace.
The list of outstanding forwardports was pretty messy as the ordering
was unclear and there was little way to really drill into the thing.
* Shows outstanding forward ports sorted by merged date ascending, the
oldest-merged PRs are the ones most in need of fixing while PRs
which were only just merged can safely be ignored.
* List reviewers with outstanding forward-ports, allow filtering by
clicking on their name, allow deseleting through the subtitle of the
page.
* Don't display reviewer in list when page is already filtered by
reviewer.
Also improve PR page a bit:
* Add reviewer.
* Add direct link to backend (closes#524).
Closes#529
Though the forwardport posts regular reminders that an fw is outdated,
it can be easy to miss for the non-subject (and apparently the
subjects often just ignore the information entirely).
Add a few relevant links there:
* on PR pages, add a link to either the source or the
forward-ports (if applicable), as well as the merge date
* add a new page which lists all the PRs with outstanding
forwardports, as well as the forwardports in question
Fixes#474
Genericise runbot_merge's tagging (move states to the "UI" but only
store / manage actual tags), and remove forwardport.tagging as it's
now redundant.
Closes#232
During freezes it can be useful to notify viewers that nothing is
going to forward port or merge for a while, and that this is
intentional (not something that's broken).
Fixes#307
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
When posting a reminder that there are open / waiting forward ports on
a source PR, also post *which* PRs those are.
While at it, move the cron code in a proper python file (so we can use
stuff from odoo.tools), and fix display_name so we can straight use
display_name as a github ref' ({owner}/{repo}#{number}). This impacts
log-grepping but it seems like an improvement nonetheless.
Closesodoo/runbot#228
Having all the feedback be sent by the mergebot user (github_token) is
confusing. Add a way to specify which field of project should be used to
source the token used when sending feedback.
Fixes#190
* don't warn on every PR on the dot every week, instead wait for the
PRs to be "sufficiently old" (at least 3 days)
* after discussion with bugfix, the reminder ping should be sent every
day following the PR being "old enough"
* run the cron every day instead of every week
* add an override context key for test purposes
Closes#198
* 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.
