Caolan

• landlock stuff
  • document what systmp and the childroot tmp directories hold
    → https://gerrit.collaboraoffice.com/c/online/+/9837
  • compare against namespaces, settings/multi-tenant not as well
    supported with landlock given that with namespaces we can mount
    the “shared” part into the tree.
  • best to just rework that to be land-lock friendly instead
    → https://gerrit.collaboraoffice.com/c/online/+/9975/7
  • get cypress etc to pass under landlock with dbgutil enabled
    • various tests deliberately have files that don’t exist that
      trigger asserts with landlock enabled, rework those and add a
      way to tag attempt to open in rw things that are allowed to
      fail so they don’t abort, e.g. probing if shared autotext is
      writeable
      → https://gerrit.collaboraoffice.com/c/online/+/9924
• coda stuff
  • inserting a slide from the sorter left the following slide current
    → https://gerrit.collaboraoffice.com/c/online/+/9525
  • sc: mark the csv import dialog’s kitPoll re-entry as expected
    → https://gerrit.collaboraoffice.com/c/online/+/9963
• email TODOs backlog
• an experimental build should not override the exotic file formats setting
  → https://gerrit.collaboraoffice.com/c/online/+/9932
• don’t ask exotic filters about content when LoadExoticFileFormats is 0
  → https://gerrit.collaboraoffice.com/c/online/+/9931
• strip perf’s " (deleted)" suffix before stackcollapse-perf.pl
• to improve flamegraphs when something does wrong, e.g. upgrade in flight (maybe)
  → https://gerrit.collaboraoffice.com/c/online/+/9922
• COVERITY_SUPPRESS_ASSERT=1519 to get coverity usable again
  → https://gerrit.collaboraoffice.com/c/online/+/9971
• push landlock stuff around a bit more
• backport various things
• various efforts to make non-incremental windows build fast
  • skip the python KillPython step so two windows builds don’t race over it
    → https://gerrit.collaboraoffice.com/c/online/+/10183
  • also skip the nss command-line tools in the gyp build
    → https://gerrit.collaboraoffice.com/c/online/+/10294
  • don’t let msbuild reuse its worker processes between builds
    → https://gerrit.collaboraoffice.com/c/online/+/10272
• poke at CODA webview tear down for bg tabs and recreate on fg
• very slow xlsx save on millions of intermediate blank rows before hitting a final line of content
  • xlsx export: skip blank cells that XclExpRow::Finalize drops again
    → https://gerrit.collaboraoffice.com/c/online/+/10386
  • xlsx export: collect the areas of a row before making any cell records
    → https://gerrit.collaboraoffice.com/c/online/+/10385
  • hide the calc cell cursor when switching sheet
    → https://gerrit.collaboraoffice.com/c/online/+/10300
• crashtesting: pass the collected page number to CheckMovedFwdCondition
  → https://gerrit.collaboraoffice.com/c/online/+/10147
• the biggest remaining crashtesting cluster
• big cluster of ci issues
  • skip the multi-page cursor test in multiuser/writer/cursor_spec.js
    → https://gerrit.collaboraoffice.com/c/online/+/10423

Mike

• PPTX 2st page background added after save

  • Fixed

• Crash when switching to Print preview from LO started from Java app

  • Fixed in main

• FILEOPEN: DOCX images are vertically cropped in LibreOffice Writer and LibreOffice-generated PDF, while rendering correctly in Microsoft Word

  • Fixed in main

• tdf#173160, tdf#167713

  • fixed regressions from earlier work

Tomaz

Vector rendering for online:

• Text prediction
  • Reviewed required commits for text prediction
    • need more attributes added to the text primitives that need to be taken into account
    • need exact cursor information - paragraph + index
    • added logging of text prediction again
• Animations for slideshows
• Adding support for missing primitives
  • Fix hairlines to be 1px in width regardless of the zoom level
  • Fixed issue with font faces - bold, italic were applied multiple times
• Master view rendering
  • Need special handling as it renders parts that are filtered in slides
  • Change to filter in client - when that is possible
  • Still we need to request
  • Master slide reuse
• Notes view
  • Analyzed what is needed

PPTX->ODP->PPTX regression - green shape

• Done, merged and confirmed

Working to get LAMBDA support into Calc:

• Look into OOXML compatibility issues [4]
  • Added many more cases
    • array union and intersection combined by @ or #
    • % combined by @ and #
    • checked and added a new MSO crafted self-asserting test document
    • added the roundtrip test on the document
    • added the ODF roundtrip test on the document
    • added a formula check when round-tripping so the formulas stay the same
    • probably makes sense to create more self-testing documents in MSO like tha as they cover a wide variety of checks for formulas (our existing self-asserting test are written in fods, so those check the formulas and import only)
  • Added Aron’s document to the tests and fixed the remaining XLS->XLSX issues
