Introduction
[edit]From task T282740:
I made a table contain containing all Tasks and tried to order them by priority from 1 (highest) to 94 (lowest).
37 of 94 Task did not contain a Priority, I tried to triage them.
The current priorities are imho sometimes a bit inconsistent: phab:T36947 Incorrect text positioning in SVG rasterization (scale/transform; font-size; kerning) set is set to high but it can be solved by e.g. tasks that are set to low: phab:T265549 Update librsvg to > 2.44.10 and phab:T40010 RFC: Re-evaluate librsvg as SVG renderer on Wikimedia wikis. Try to make it a bit more consistent, but generally tried to keep the old priority if set.
Currently "Wikimedia-svg-rendering" has two boards: "Backlog" and "Fonts to install", however I would like to split them more well-arranged in 8 boards, otherwise it is dificult to have a clear view:
- Backlog (3tasks)
- Fonts (11tasks)
- MediaWiki (21tasks)
- Client-side-rendering (7tasks)
- update librsvg (28tasks)
- Unresolved librsvg-bug (20tasks)
- Math formula (4tasks)
I would set everything related to librsvg-bugs to "Stalled".
The duplicates I will suggest/discuss at the individual task, before taking an action. The suggested declined/invalid ones, I might mention them to think about it, but I would keep them open for now.
I highlighted in yellow the suggested changed priorities and the suggested changed status, and the missing upstream-labels.
I made the table-columns "related to T40010" and "related to Math formula", 1==true means it is related. 54 Tasks are related to phab:T40010, which has the highest number of subscribers, that's the reason why it is the only one with "high" priority.
I made the table-columns "Update to librsvg 2.51", "resvg", "Inkscape", 1==true mans that is fixed, 0==false means it is not fixed, empty means that it is not related.
- Updating librsvg fixes 28 tasks (not counting the two update libsvg-tasks)
- resvg fixes ~45 tasks
- inkscape fixes ~40 tasks.
