Documentation on coext ODF extensions (Regina)

  • See <https://forum.collaboraonline.com/t/cool-tc-meeting-agenda-2026-07-22-16-00-cest/4885/2>

  • ODF requires documentation for the coext namespace

    • LO documents the loext namespace in the TDF wiki

  • Idea was to copy the relevant pages from the TDF wiki to somewhere on COOL infra (Michael S)

    • perhaps in git

    • haven’t gotten around to do that yet

    • some lightweight markup would be ideal, to have copy easy from/to markdown

    • dev-notes/ already has developer documentation, hosting it there would be an option (Miklos)

  • Suggest to came up with a proposal for next week (Michael S)

Release Engineering update (Andras)

  • Releases

    • COOL 26.04 this week, cp-26.04.2-3 is tagged already

Bug reporting

Jenkins / CI update (Adria)

  • Mohit’s monorepo test change

  • Szymon’s monitoring: “last builds” monitoring

    • Week 30: Cypress clean pass: 21%, 567/723 have at least one “retry”

    • Better than last week

  • The Windows build broke this week (Regina)

    • –disable-pch gives you the config which is tested in Jenkins (Miklos)

    • CI uses ccache, not pch

    • It is *believed* that ccache and enable-pch don’t work together. But I wonder if that is true (Caolan)

    • If pch breaks, it’s easy to fix it (Michael S)

    • Open the pch file, the top of the file has a comment with a commandline to re-run, then it works

  • Gerrit for online main

    • Week 30: Success rate is 34%, failed builds are 33/50

    • Week 30: Turnaround time is 3 hr 16 min (median of last 30 SUCCESS/FAILURE builds)

    • New Windows instance is added, almalinux9 agents are added (Adria)

    • Almost all the jobs have more than one host to build on

Crash testing (Caolan)

  • 2026-07-22: 55 (-37, +0)

    • more good progress

  • 2026-07-15: 92 (-79, +0)

    • progress on the new crashes, and some more of those hopefully fixed in the next pending run

TTT talks

What’s cooking

  • Stephan

    • Having working cypress tests locally now (with -j2)

      • Visual testing finds differences locally where it passes on CI

      • trying to make a toplevel ‘make check’ work; CI only runs parts of ‘make check’ in separate sub-jobs

    • Back to scripting / collaboration

  • Miklos

  • Caolán

    • looking at if the bottlenecks in the non-graphical tests

    • seems parallelism can be improved there, both inside and outside engine/

  • Adrià

    • K6 VM in mersenne for performance and load tests, connected to bee jenkins

    • configuring new windows agent (gardner) to build coc-25.04 and coc-26.04 builds (online main already working)

    • **Creating branded CIB Office from co-25.04 branch
      **

  • Szymon

  • Michael S

    • poppler and libxml2 updates

    • libxml2, cmake: does cmake do its own parallelism? (Caolan)

      • Not checked (Michael S)
