When components / flags selected --> maintain consistency in coverage data across `repo overview`

[jerrodcodecov]

What product do you want to improve? Repo overview page

Is your feature request related to a problem? Please describe. Right now, when you select certain set of components or flags on a given branch, it's actually not obviously in the file tree what the overall coverage is for the selected set of components or flags

Describe the solution you'd like I think it would make sense to include a "total" or "sub-total" in the file tree view

Describe alternatives you've considered Alternatively, we could also have the sunburst, coverage over time and repo coverage numbers update dynamically as components are selected.

If we don't take this approach, we should additionally clarify that the "selected components / flags" are only applicable to the file tree, and not metrics "above the line"

@codecovdesign seeking an update on ingestion on this matter, thanks!

[codecovdesign]

@jerrodcodecov thanks ping, marking in-discovery, adding to design sprint (upcoming) and will finalize/prep to dev ready

[codecovdesign]

@katia-sentry here's demo/prototype based on the description suggestion. The design can be broken down in different ways and depending on the constraints the page could work together or separately; here are areas it'd be great to look at:

• If user applies selection to sunburst, the files match the selection
• If filters are applied subtotal of the lines shown, per the component/flag
• If either are applied, the summary atop also aligns to the main selection
  • this could be one part that doesn't coordinate to the selection (remains as repo data)

Could we schedule a design/eng discovery around this one?

[katia-sentry]

@codecovdesign yes we can schedule a sync for this with @RulaKhaled and @rohitvinnakota-codecov

[codecovdesign]

review with @rohitvinnakota-codecov @RulaKhaled 3/20

• create bug issue for sunburst path vs file path (sunburst showing) https://github.com/codecov/engineering-team/issues/1442
• Rola: partial to show the summary as a constant (showing repo data)
  • related would be then to move the filters above the charts since it controls the data below
• initial iteration to consider: display sub-totals below files table when filters are applied

[codecovdesign]

review 2 with @rohitvinnakota-codecov and @RulaKhaled

• today components file data corresponds to filters applied
  • however flags data appears to have issues when filters are applied
  • example: see applied filter here is not filtering (https://app.codecov.io/gh/codecov/worker?flags%5B0%5D=latest-uploader-overall) but at the file level it does appear (https://app.codecov.io/gh/codecov/worker/blob/main/database%2Fbase.py)
    • related bug issue: https://github.com/codecov/internal-issues/issues/370
  • based on this will revisit #1453
• interim there is a bug issue to resolve: #1455

Next steps are to resolve the bug findings, then revisit the updates to filtering / sunburst etc

[vlad-ko]

Do we have any update that I could share with the customers?

[codecovdesign]

@vlad-ko it looks like the initial blockers have been addressed; tentatively moving https://github.com/codecov/engineering-team/issues/1453 to dev ready cc @katia-sentry

[katia-sentry]

Thanks @vlad-ko @codecovdesign. I've added https://github.com/codecov/engineering-team/issues/1453 to next sprint
