Bug reporting

Jenkins / CI update (Adria)

  • Mohit’s monorepo test change

  • Szymon’s monitoring: “last builds” monitoring

  • Gerrit for online main

    • Week 36: Success rate is 50%, failed builds are 25/50

    • Week 36: Turnaround time is 48 min (median of last 46 SUCCESS/FAILURE builds)

      • Yesterday was pretty good (Adria)

  • Getting the slow Intel Mac builder off ? (Michael M)

    • Due to work on new Mac hardware setup tomorrow (Adria)

      • Mac Intel is off already.

TTT talks

Multi-process modeling (Michael M)

  • Simulating processess …

    • Would help with the macOS rules where you can’t fork inside the sandbox

  • Can we find and group our global state together

  • Don’t have a mechanism to make sure global state is protected (Miklos)

    • could have accessor pattern – can’t access without first locking it.

    • Might be able to do this without too much effort ?

    • Not a fan of lots of mutexes (Michael)

  • Global state → shared thread-local … (Quikee)

    • not screaming and running around – formular-bars – in a global state …

      • made it thread-local – could help multiple formula-bars at the same time – was working.

  • Mildly amused (Caolan)

    • tried to put all these things into local functions – to get auto C++ thread-safe mutex

      • need to re-think all of that perhaps

      • no real feeling one way or the other.

  • Benefit for anything non-Mac-OS (Stephan)

    • can’t do fork for background save – like multiple-processes …

    • May be useful for Android + iOS (Michael)

    • Safer to spawn a process (Stephan)

    • only useful for CODA (Michael)

      • Don’t use this stuff FakeSocket … could spawn on Windows / Linux but don’t.

    • Any crash brings all ‘processes’ down (Michael)

      • seems scary but … auto-save in CODA etc.

What’s cooking

  • Miklos

  • Szymon

    • JSDialog fixes for reloading toolbars

    • Working on Impress

  • Adrià

    • **Added more CI capacity. **

      • +10 new linux agents for linux related jobs (cypress, android, dbgutil, etc.)

      • Working on enabling windows agent on incus VM to increase capacity. Goal -> to scale easy

      • Start working on enabling 2 new macmini M4 to increase macos / ios CI capacity

      • **retired Mac based on intel **

    • Monitoring enhancement - working on new grafana dashboard for CI (jenkins api + prometheus) to help identifying issues and taking remediation actions

  • Stephan

    • GAS-like (Writer) JS extensions API

  • Caolan

    • An --enable-qt app build which coexists with server online, so one build for both outputs

    • An effort to have the “make clean” work done in parallel with make

    • I think it might be plausible to make msbuild do some more parallel building if some of the externals are shown to be a bottleneck

  • Andras

    • SBOM / supply chain

      • Docker: image-level SBOMs generated at build time; images published the way ZenDiS publishes its hardened bases

      • VEX: triaged all remaining SBOM scan findings (raptor 2.0.16 CVEs as fixed / not affected, two open items closed)

      • ** Dependency bumps: OpenSSL 3.5.8, Python 3.14.7 (off the 3.14.5rc1 pre-release), d3 7.9.0 (d3-color ReDoS fix), dompurify 3.4.14**

    • Engine dead code and UI removal

      • **Desktop notebookbar fully removed: implementation, UI variant data files, UI mode chooser, User Interface dialog, addon
        merging, SID_NOTEBOOKBAR, vcl leftovers, unread toolbar mode properties, stale log area
        **

      • ** Tools - Customize dialog removed (made unreachable, then dialog, slot ids and strings)
        **

      • ** Help - Send Feedback removed
        **

      • ** org.openoffice.Office.ExtensionManager configuration removed
        **

      • ** Old .NET Framework (CLI) UNO bindings and dead /clr gbuild support removed; CODA-W no longer builds the .NET UNO bridge**

    • CODA-W build without WSL, we can use MSYS2. WSL still works but MSYS2 is “advertised” in documentation

    • Localization: AI chat sends stable message codes so the client can localize them

    • Accept CIDR networks in every host allowlist – former regex syntax will work as well.

  • Tomaz

    • Vector rendering: master pages, note pages

      • More primitives: glow effect

  • Mike

    • Preparing for work on re-introducing multi-line links in PDF/UA, dropped earlier because of perf issues. Not started yet.
