# Caolan

- experiment with splitting up StorageBase::validate to  
see if the piece that uses DNS could use the async DNS  
and get its cached result. so this piece gets the same results  
as the async connect.
  - that looks plausible for wsd/RequestVettingStation.cpp  
and wsd/wopi/WopiProxy.cpp
  - but less so for the StorageBase::create use

- maybe if we do the dns query at the entry point to the whole  
process and bubble resolvedHost alongside the uri throughout
  - trying this becomes unwieldy pretty fast

- rework sync dns to reuse async dns to share its cache,  
more straight forward at least

- memory-optimization
  - fix coolmap crash
  - prototype calling type detection during preload to share that  
between children, need to provide zip data to get it to load  
office file format related stuff

- file descriptor leak seen with cypress tests
- turns out that this is since the autotext presets installation,  
nothing closes the sockets used to download these. A sync download  
will close the socket as a side effect of how that works, but async  
download doesn’t.
- file descriptor leak
- A plausible fix for the new ones

- I think there are two additional sockets per document “leaking”,  
maybe from the fileserver keep-alive, needs some more examination
- memory-optimization, submit patch to preload typedetection

# Mike

- Missing “underlining” on a long row of space characters
  - A “regression” from [https://gerrit.libreoffice.org/c/core/+/161400](https://gerrit.libreoffice.org/c/core/+/161400)
  - Missing support for Word’s ulTrailSpace compat option
  - Tried to avoid making SwHolePortion for the part that needs to stay underlined
  - That breaks “Word-compatible trailing blanks”, because it starts to participate in alignment (it must not)
  - An idea: split the SwHolePortion into two, and make the one inside the page margins to draw underline
  - Making it in SwTextGuess::Guess is complicated; breaks the smart shrinking feature
  - SwTextPortion::Format\_ looks suitable
  - Some pre-existing problems need to be fixed
  - Merged the master patches
  - The remaining problems postponed

# Tomaz

PPTX – font embedding

- Making MSO accept LO embedded fonts

- MSO has cloud fonts, which will download the font in case the font is missing
  - makes it a PITA to figure out if the font is actually used - need to turn off connection and delete the cache
  - a bit of success with Roboto font - it seems
    - it used the font and it also exported the same font

  - most fonts still don’t work however and not at all in MSO Online
  - trying to do EXACTLY what MSO does, but this needs also attributes that we currently don’t export (panose and stuff)
  - and as close to the EOT structure as MSO uses… (version 0x00020002 instead of 0x0002001 we use) even if it doesn’t make a difference
  - stop with this for now to get other needed bits in (embedded font import), then fix this afterwards

- Implemented import of embedded fonts
  - round-trip works fine - we can read EOT perfectly unlike MSO

- Added TTF Reader - will reuse more code in the future with sft.hxx
  - Tested reading of Ahem.ttf testing font

- Added more tests
