https://cgit.freedesktop.org/harfbuzz/commit/?id=3d9a0306ebb48706778fd2c487c3cacc7d508d6c Overview of changes leading to 2.0.0 Wednesday, October 17, 2018 ==================================== - Added AAT shaping support (morx/kerx/trak). Automatically used if GSUB/GPOS are not available respectively. Set HB_OPTIONS=aat env var to have morx/kerx preferred over GSUB/GPOS. - Apply TrueType kern table internally, instead of relying on hb_font_t callbacks. - Khmer shaper significantly rewritten to better match Uniscribe. - Indic3 tags ('dev3', etc) are passed to USE shaper. - .dfont Mac font containers implemented. - Script- and language-mapping revamped to better use BCP 47. - Misc USE and Indic fixes. - Misc everything fixes. - Too many things to list. Biggest release since 0.9.1, with over 500 commits in just over 5 weeks! Didn't intend it to be a big release. Just happened to become. - hb-ft now locks underlying FT_Face during use.

Let's give this release a bit of time to settle, and get past the Fx64 soft-freeze before we consider taking it.

I ran 2.0.0 through Try just to see where things stand. I ran into two new issues: MSVC Werror build bustage: https://treeherder.mozilla.org/logviewer.html#?job_id=206684240&repo=try Looks like we have 3 in-tree uses of the old API that'll need switching to the new one. Android reftest failures: https://treeherder.mozilla.org/logviewer.html#?job_id=206687164&repo=try These hit both opt and debug builds, so I'm pretty sure it's real.

When we're ready to take the harfbuzz update, this should fix the issue of the deprecation warnings.

Comment on attachment 9030085 [details] [diff] [review] Update gfxFont/gfxFontEntry to use new harfbuzz API in place of deprecated functions Looks great, thanks for figuring that out! https://treeherder.mozilla.org/#/jobs?repo=try&revision=6f7e7bbe5779402b15e137cb081fabae813e27d2 Happy to land this all together once the reviews are ready to go :)

OK; I'm intending to keep an eye on stability upstream, and consider taking an update sometime in January. Leaving ni? flag as a reminder.

Overview of changes leading to 2.3.0 Thursday, December 20, 2018 ==================================== - Fix regression on big-endian architectures. Ouch! - Misc bug and build fixes. - Fix subsetting of simple GSUB/GDEF. - Merge CFF / CFF2 support contributed by Adobe. This mostly involves the subsetter, but also get_glyph_extents on CFF fonts. New API in hb-aat.h: +hb_aat_layout_has_substitution() +hb_aat_layout_has_positioning() +hb_aat_layout_has_tracking()

2.3.0 looks good on Try. https://treeherder.mozilla.org/#/jobs?repo=try&revision=1757eeedfae73fd1f54c704f73144c47fce11106

Comment on attachment 9030085 [details] [diff] [review] Update gfxFont/gfxFontEntry to use new harfbuzz API in place of deprecated functions Review of attachment 9030085 [details] [diff] [review]: ----------------------------------------------------------------- This just adjusts our code to use non-deprecated harfbuzz API and avoid build failure due to warnings-as-errors, without changing behavior. I expect we'll also want to add the new Indic-script v.3 tags to the ScriptRange records where appropriate (so I've left room in the struct for them), but let's do that in a separate bug.

Coverity found 18 new issues in this update. Complaining about dead code, Large stack use, and other things. No high impact defects (medium and low)

> Behdad, do you have access to Coverity results for HarfBuzz? Hey there. To be honest enabling it was my task but I got stock as the lack of familiarity, can you guys help us on enabling it again with our CI?

Seems that it is here: https://scan.coverity.com/projects/harfbuzz And see here: https://scan.coverity.com/faq#get-account If you want, we can share the results I was mentioning above.
