Bug reporting

Jenkins / CI update (Andras)

  • Mohit’s monorepo test change

  • Szymon’s monitoring: “last builds” monitoring

  • Gerrit for online main

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

  • Current state: pretty stable (Andras)

    • 2 breakages yesterday (one unstable test, then wasm)

  • New hardware:

    • right now, it looks stable (Adria)

    • slower than ideal during peak hours; almost idle over the weekend (Andras)

    • Turnaround time? (Miklos)

      • good to have the median not avg …

      • getting the last ~100 builds …

  • AI: extract and log the build times – and present them next & every time (Adria)

    • E.g. what is the median turnaround time for “Gerrit for online main” in the last 50 builds

    • online.git scripts/cool_tc_stats.py ← extend this (Miklos)

  • There is ccache on windows machines which is great (Caolan)

    • Compiling without optimization might go quicker on Windows

    • gcc omits various warnings if not optimizing, not clear if windows does.

  • What is the slowest job? (Michael M)

    • Windows is stabilizing, but flatpak is the slowest one …

    • Depends – if something changes something fundamental in engine/ makes a big difference.

  • Competing patches – both pass CI, but when both merged everything fails (Andras)

    • a huge queue piles up immediately when things go wrong.

  • Brings back the previous idea – for releng to bump build-fixing patches to the top of the queue (Caolan)

    • if confident – just merge it without waiting for CI and let people know

    • yesterday – Andras stopped 40 Jenkins jobs that would fail anyway; but we’d have to wait a day to see them fail.

  • We could instead abort as soon as a single platform fails ? (Miklos)

    • great if it’s a compiler error (Caolan)

      • bad if it’s Windows has run-out-of-space …

      • how to decide which is which.

  • **Caolan says: https://plugins.jenkins.io/PrioritySorter/ **

  • We could have bad commit ranges (Noel)

    • just abort all builds in those ranges

  • AI: install PrioritySorter (Adria/Timar) → and re-start at the weekend.

Crash testing (Caolan)

  • 2026-06-17 192 (-34, +0)

    • MatrixResizeGuard for ScColumn::CalcAll fix in motion

    • unshare formula cells the matrix import overwrites

  • Expect the run after next to be even better

  • Waiting for Aron’s feedback on the SmartDoc consensus

    • lets dump them all in.

  • Can we write a batch fetching script for PPTX/PPT bits ? (Michael)

TTT talks

What’s cooking

  • Stephan

    • Noel’s OUstring work, completing that

    • CODA collaboration, getting that past review

  • Noel

    • looking at the cpo namespace rename (C++)

    • looking at doing this incrementally

  • Miklos

  • Caolán

  • Adrià

    • CODA flatpak snapshot repo and setup to daily generation. Debug flaky(?) job

      • Debug why flatpak job is flaky in fermat (not in mersenne)

      • could allow add more flatpak build capacity

    • Cleanup github 24 & 26 jobs and ws from jenkins (migrate github 24 jobs to gerrit)
