Bug reporting

Jenkins / CI update (Adria)

Crash testing (Caolan)

  • 2026-10-07: 22 (-3, +17)

    • mostly my own “basic” init during basic init recursion problem

  • 2026-09-30: 8 (-1, +0)

    • good result, out of ~700k

  • Not decided what to do with the next ~million test documents …

    • could we run a long one over the whole set ? (Michael)

  • thinking about using excess Jenkins build power at the weekend to do this fast (Caolan)

    • should also move away from classic / soffice.bin pieces …

    • then plumbing can be someone else’s …

  • can we move to COOL to be safer & better contained (Michael)

    • we do a ton of convert-to type end-points – converting important to non-important.

    • AI: ask Adria to help out here (Caolan)

TTT talks

Killing soffice.bin inside COOL (Michael M)

  • Continuing to work on this …

  • getting performance of top-level compile good … tests/ code is too slow …

    • should be small & snappy …

    • better integrating

  • What about missing pieces ? Forms & Mail-merge (Noel)

    • Forms inside writer documents …

    • We have decent support for content controls in COOL (Miklos)

      • and form fields are there too, not an issue.

      • Minimal support for shape-based forms – where MS equiv. is ActiveX

        • want to hide this as much as possible.

        • but click → VBA macro bits may have minimal support still.

    • We’re not shipping / supporting soffice.bin from the CODA branch anyway (Michael M)

  • UI tests – are still using soffice.bin (Miklos)

    • just the headless/ one on Linux – so we can drop other VCL backends …

    • CI will complain about this anyway if there is a problem.

  • created coconvert thing – to make bisection / file-conversion better

    • Aron is improving that to make it command-line argument compatible to help bisectors.

  • Nice to drop chunks of code-paths there, threading horrors, VCL weirdness,
    and non-LOK code-paths.

What’s cooking

  • Szymon

    • mostly doing reviews

  • Stephan

    • extensions served from `make -C browser install-demo-extensions` should now work in all CODA-M,-Q,-W (–enable-debug, --enable-experimental) builds

  • Caolan

    • some coda crashes (xlsx Yield during load allowing an interleaved ‘inner’ load) confusing who should get the message.

    • eslint now warns if you would attempt to use .innerHTML

  • Adrià

    • windows11 incus vm copy from physical hosts

    • help debugging RAM issues on new hardware

    • clang loplugin – job modification + enabling almalinux9 agents to run it

    • grafana panel to show build, queue times and success rates for jobs

  • Miklos

  • Michael S

    • SBOM improvements

  • Michael M

    • Compile performance work

      • chrono is surprisingly expensive to include … for a 64bit nanosecond …

      • splitting modules, reducing dependencies

      • getting in-line code out of headers …

      • PCH → could this be the default for clang ? … (Michael)

        • working with gcc nicely with --enable-pch=full on linux + ccache (Noel)

    • Cleaning up the top-level test/ compile performance

    • Database connectivity bits …

      • would be good to remove them …

  • Quikee

    • Added reflection effect

      • Added Sliders to JSDialog – used in Sidebar for the reflection effect

    • Vector rendering

      • delta and slide/master/note page fixes, then can start draining Armin’s commits from the branch

  • Andras

    • release engineering

    • tinderbox for PHP Proxy (cypress fixes + 1 fix to proxy.php already)

      • we run quite a lot of the cypress tests – only a few are removed for proxy.php …

  • Regina

    • working with Armin on SmartArt, ongoing

  • Noel

    • **Looking for feedback on --enable-libunited https://gerrit.collaboraoffice.com/c/online/+/6046**

      • could we use -ffunction-sections and a profiler to work out what is called (Michael)

        • and shuffle that code next to each other …

      • get it in without tunrning it on → and then switch it on later ?

      • Needs 500 symbols for internal symbol lookups with dlsym() aronud the place …

    • removing/replacing macros like SAL_CALL/SAL_DELETED_FUNCTION

    • very very very slowly merging Outliner into EditEngine.
