# Caolan

- use embedded thaw/freeze to make navigator optimization for  
online easier on the eye.

- harfbuzz upgrade causes crashtesting asserts  
engage with behdad to get it sorted  
 → [increase maximum set\_flags range by caolanm · Pull Request #5315 · harfbuzz/harfbuzz · GitHub](https://github.com/harfbuzz/harfbuzz/pull/5315)
- fix a set of crashes seen in 25.04 crashreports

- coolwsd memory work, malloc\_trim on all idle  
 → [malloc\_trim when idle by caolanm · Pull Request #11875 · CollaboraOnline/online · GitHub](https://github.com/CollaboraOnline/online/pull/11875)
- push clipboard work forward a little more
- crash in coolwsd  
 → [lockStateUpdateRequest holds ClientSession by weak\_ptr by caolanm · Pull Request #11888 · CollaboraOnline/online · GitHub](https://github.com/CollaboraOnline/online/pull/11888)
- slides for cool days
- help bayram with bisect and mystery header issue
  - bisect doesn’t really help in the end, points to changes  
in what headers get imported rather than the substantive issue
  - One issue at least seems to be that writer doesn’t allow a  
combination of header/footer/body to give a body area less  
than 20% of the page height.
  - next step: Debug SwHeadFootFrame::GrowFrame and find where  
the desired height is limited/clipped/bounded.

- crashes seen in co-25.04

- Check a11y in online. GNOME desktop accessibility + online screen  
reader enabled doesn’t do much in chrome. But works in firefox, so  
for purposes of checking that a11y is successfully enabled that  
combo works fine.
- memory optimization: have a look at pahole output for some  
calc structures.

# Mike

- Calc slow with Select All
  - The speed-up in co-25.04 is due to Armin’s ITEM work; no way to backport that
    - Had some additional perf improvements in master for the new code, found during code reading; cherry-picking to co-25.04

  - So searching for a way to optimize the iteration algorithm in sc, to avoid need of too many SfxItemSet lookups.

# Tomaz

PPTX – font embedding

- Added test for Export (as it doesn’t depend on libeot) and a round-trip test (which depends on libeot.
- Change libeot to be enabled by default - first on Linux and macOS
  - Windows doesn’t compile

- Making libeot compile on Windows by using gbuild instead autotools
  - fix build issues on Windows - err.h is not available on Windows, but it is not even used, so remvoe the include
  - also only build libeo, not the eot2ttf tool, which uses err.h

impress -PPTX - image resied : the ratio isn’t kept

- Weird issue with the “Position and Size” dialog
- Seems that enabling “Keep ratio” doesn’t actually select that in the dialog code in core (looking at the video)
  - on OK we remember the state of the “keep ratio” check box, but next time we enter the dialog the “Keep ratio” is disabled

- There are other issues with the dialog, which could be related
  - enabling “Protected / Position” doesn’t disable spin boxes or “keep ratio” checkbox
  - disabling “Protected / Position” doesn’t enable back the “Protected / Size” checkbox so can’t change that option
  - seems there are issues with state synchronization in that dialog on COOL
