   action-166 mobile perf

   Vlad: useful but not critical

   kuettel: chrome on android is using woff2 without issue

   kenji: several metrics, such as when font cant be used, was 30%
   ... now its 25% and its mostly because of woff2 as well as some
   other optimisations.
   ... also a metric for how long to display the text. was 630ms
   now 400ms so woff2 has improved things
   ... compared to woff1
   ... data is sent from chrome users who agree t send stats.
   these are from chrome 35
   ... compared to chrome 37 with woff2

   rod: there was an issue about higher battery life

   kuettel: prefer to keep this action open as we add more data

   kenji: memory might be tricky, needs more analysis

   action-122?

   <trackbot> action-122 -- Raph Levien to Investigate the TTC
   support as part of the WOFF 2.0 pre-processing mechanism -- due
   2013-10-30 -- OPEN

   <trackbot> [14]http://www.w3.org/Fonts/WG/track/actions/122

     [14] http://www.w3.org/Fonts/WG/track/actions/122

   trackbot, status

   (suggests adding Kenji as he is missing from trackbot users)

   kuettel: was not clear what we decided earlier. css webfonts
   does not support ttc

   behedad: its in the CSS3 spec but not implemented

   kuettel: raph had suggested a way but it was not prototyped

   Vlad: adobe has been active to extend TTC to OT collection with
   CFF fonts
   ... so guessing they see it as important

   kuettel: christopher slye had been contacted to see if adobe
   was interested.

   Vlad: christoopher stepped down, Adobe have another rep now

   (wg members
   [15]https://www.w3.org/2000/09/dbwg/details?group=44556 )

     [15] https://www.w3.org/2000/09/dbwg/details?group=44556

   kuettel: so we could prototype

   rod: sure, could look at that. what was raph's suggestion?

   kuettel: look at scope of changes, then consult with behedad
   and raph
   ... should not change wire format

   (re-assigned to Rod with target 31 oct)

   actoion-129?

   action-129?

   <trackbot> action-129 -- David Kuettel to Prepare a mime type
   application draft and justification for top-level "font"
   registration (with Vlad) -- due 2014-02-05 -- OPEN

   <trackbot> [16]http://www.w3.org/Fonts/WG/track/actions/129

     [16] http://www.w3.org/Fonts/WG/track/actions/129

   kuettel: takes a long time, is not blocking

   Vlad: as with woff1 we will register in application subtree
   ... spoke to some folks involved, and they said unless there is
   very compelling explanation for a separate top level type, then
   it will not be accepted
   ... but it is at least possible now

   kuettel: target date Jan 31 2015

   action-132?

   <trackbot> action-132 -- David Kuettel to Track progress of
   Brotli specification to RFC -- due 2014-09-10 -- OPEN

   <trackbot> [17]http://www.w3.org/Fonts/WG/track/actions/132

     [17] http://www.w3.org/Fonts/WG/track/actions/132

   zoltan says spec has been sent as ID, needs feedback, WG could
   help for review

   action chrisl to use ietf-w3c liaison to get review and
   guidance for next steps on Brotli ID

   <trackbot> Created ACTION-146 - Use ietf-w3c liaison to get
   review and guidance for next steps on brotli id [on Chris
   Lilley - due 2014-09-23].

   kuettel: compression team thrilled to see brotli picked up and
   deployed in browsers

   action-133?

   <trackbot> action-133 -- Raph Levien to Review the spec edits
   and finalize the definition of the "nominal size" -- due
   2014-08-20 -- OPEN

   <trackbot> [18]http://www.w3.org/Fonts/WG/track/actions/133

     [18] http://www.w3.org/Fonts/WG/track/actions/133

   Vlad: raph still intends to clarify this, by early october
   ... critical, as little benefit and hard to implement
   ... not enough info for decoder to allocate memory with
   confidence

   ChrisLilley: agree, its not like woff1 which had a guarantee
   due to bitwise identical, not the case here

   Vlad: alternative is to specify an exact implementation but
   that constrains implementation

   rod: its clear ppl have to manage memory themselves

   Vlad: goal with mtx was optimal decompression
   ... original size may be a good estimate of required size but
   is not a guarantee
   ... keep action on raph

   action-138?

   <trackbot> action-138 -- Vladimir Levantovsky to Review
   conformance statements for woff 1.0 and transfer the applicable
   ones over -- due 2014-09-17 -- OPEN

   <trackbot> [19]http://www.w3.org/Fonts/WG/track/actions/138

     [19] http://www.w3.org/Fonts/WG/track/actions/138

   Vlad: sent an email

   [20]http://lists.w3.org/Archives/Public/public-webfonts-wg/2014
   Sep/0016.html

     [20] http://lists.w3.org/Archives/Public/public-webfonts-wg/2014Sep/0016.html

   Vlad: in woff1, we tried to reproduce same structure as sfnt so
   table directory was fixed size and padded. each table reference
   was uncompressed or separately compressed, and 4byte aligned,
   and end padded
   ... in woff2 alltable directory entires variable length, very
   small, one byte of flags plus up to 5 bytes of size, so padding
   removes that benefit
   ... thus anything about byte alignment and padding is not
   applicable
   ... so must parse whole set of enties for find where compressed
   stream starts
   ... table is not parsed until after header is decompressed. in
   multithread you conld decompress in anther thread

   behedad: its such a small bit of data, not worth optimising for
   ... its like 20 bytes

   Vlad: we have two byte reserved, not sure why

   ChrisLilley: think it was for padding only

   Vlad: could use them to hold table offset

   behedad: require it to be zero for later expansion

   Vlad: already discussed, file format requires zero but ua not
   required to fail on non-zero

   behedad: first, throwing away an extension opportunity, and
   introduce twqo ways to compute same thing so you get platform
   variabilities. dont like the redundancy
   ... currently done by computing the offset by counting

   ChrisLilley: could see that as a potential exploit

   behedad: its using it as a cache, like TT did, with bad results

   Vlad: already updated the spec to see what the wordin would
   look like
   ... added para that says it is different to sfnt; reflect exact
   order in compressed font stream
   ... theis was implied but not directly stated

   ChrisLilley: good catch

   close action-138

   <trackbot> Closed action-138.

   keep things as-is

   action-143?

   <trackbot> action-143 -- Vladimir Levantovsky to Update the
   spec in regards to the bug -- due 2014-09-17 -- OPEN

   <trackbot> [21]http://www.w3.org/Fonts/WG/track/actions/143

     [21] http://www.w3.org/Fonts/WG/track/actions/143

   Vlad: in woff 1 there were some useful notes that could be
   copied over
   ... all the checksums are screwed up, I realised
   ... due to transforms. spec is silent thatthese need to be
   recomputed

   kuettel: google implementation is recomputing the checksums
   already

   Vlad: keep 143 open for now. used to have a definition of
   transformed glyph header, and assumed sequence of compressed
   data streams. so needs entire transformed glyph sequence
   explicitly spelled out
   ... so edit spec to clarify sequence of data fields

   this relates to action-144

pending review actions

   [22]https://www.w3.org/Fonts/WG/track/actions/pendingreview

     [22] https://www.w3.org/Fonts/WG/track/actions/pendingreview

   these are all reflected in the latests spec. so unless you saw
   an issue in the spec, they are done

   action-140 causes a change in the google implementation

   kuettel: we need to update for that
   ... we need to test that change

   close action-125

   fixed, especially if it could be exploited. fuzzer is silent at
   this point. still running, but so far not found

   close action-128

   <trackbot> Closed action-128.

   ChrisLilley: not enough svg in OT to form real conclusions

   close action-126

   <trackbot> Closed action-126.

   kuettel: brotli is very good for general text not just fonts.
   works well on html and xml

   behedad: suggested svgz in svg table, more for non-web use. but
   its redundant to gzip the svg and the brotli

   Vlad: OT spec doesn't allow for gzip compressed svg

   behedad: its part of the svg spec itself

   Vlad: reasonable to allow either.
   ... for woff case it may be better to unzip and then brotli it
   ... ISO spec under final review, so not much time for comments

   ChrisLilley: so its DIS now?
   ... changes are suggested bot blocking

   (we will not require any SVG pre-processing)

   Vlad: older windows used dsig to set the icon on the font

   behedad: word only allows OT features if font has DSIG

   <Vlad> sergey, are you there

   sergeym, are you there?

   Vlad: sergey checked and no impls rely on dsig, onlyolder
   windows version to select appropriate icon

   <sergeym> I'm out of batery on my phone. Will call back as sson
   as possible

   Vlad: we dedided that making an empty DSIG had no value.
   Jonathan suggested removing it
   ... discussing dsig changes, concern over empty DSIG table
   ... can you confirm no apps rely on DSIG?
   ... older Word versions to enable OT features?

   sergeym: they do not depend on DSIG, they rely on cff vs TT

   Vlad: so we required encoder to remove dsig

   behedad: is decoder required to reject if DSIG present?

     [33] http://www.w3.org/Fonts/WG/track/actions/142

   Vlad: requires explicit bbox. was already case, adeed
   conformance requiremrent as UA and FF.

   close action-142

   <trackbot> Closed action-142.

   Vlad: google impl always drops bbox from simple glyph. ok if
   control points always on extrema

   behedad: spec is not clear if they are not extrema points. best
   to have bbbox of hull of all listed coordinates

   Vlad: (example where bbox is larger than the points)
   ... spec says that if bbox cannot be calcuilated from coord
   data, do not drop it

   behedad: impls do not do a tight ink bbox, they do the bbox of
   all on- and 0ff-curve points]
   ... spec needs to say that

   kbx: should we display warning if not?
   ... is it a minor case?

   Vlad: claim was that google drops all bboxes

   kbx: can we show its uncommon

   behedad: fontforge until recently did geometric bbox and
   truncating it, so they were all off
   ... but dropping is harmless, shifts by one unit

   kbx: we could instrument chrome to see if this shows up

   behedad: only reason there is this part of spec, is to
   accomodate fonts that are not correctly constructed

   Vlad: but tt spec does not require correctness here

   behedad: has beemn misinterpreted over time

   ChrisLilley: possible to construct one where the glyph is
   clipped away

   Vlad: (quotes, best if xmin is left side bearing) but not
   required

   behedad: bt that refers to value from hmtx table

   [34]http://www.microsoft.com/typography/otspec/hmtx.htm

W3C Process

   Chris talking about the new process at w3c re last call /
   candidate recommendation

   there used to be last call followed to CR.

   problem is that if you made changes after last call, there
   could be some issues.

   now the 2 stages are combined.

   you can make changes. Major changes trigger another patent
   exclusion.

   For 2 years, we can use the old approach or the new approach.
   After that it's only the new approach.

   We need to decide which one.

   We should also try to make a decision to go to last call and if
   needed determine what are the blocking items to get there.

   <Vlad> sergey, are you ready to call in?

   <ChrisLilley> faq
   [36]https://www.w3.org/wiki/ProcessTransition2014

     [36] https://www.w3.org/wiki/ProcessTransition2014

   Vlad suggesting we go to last call as soon as the action items
   are closed.

   in short, the old way seems more practical at this point.

   open question about rejecting on invalid checksum

   Chris / David: what did Woff 1 do in that case?

   Vlad / Behdad: it should be a note, there doesn't seem to be
   any rendering engine that actually care about the checksum

Conformance test Suite

   Vlad: would like to look at the different statement and outline
   a plan on how this could be tested

   action vlad review and edit the conformance test for extraneous
   data

   <trackbot> Created ACTION-148 - Review and edit the conformance
   test for extraneous data [on Vladimir Levantovsky - due
   2014-09-23].

   Chris: for uintbase128, need to hex edit the fonts as it
   probably would not be easy to produce all the specimen from
   regular authoring tools

   Vlad: mustAccept255UInt16 is just a matter of producing the
   specimen fonts (3 possible encodings) and testing those.

   Chris is editing the wiki

   mustRejectInvalidUintBase128

   is also doable, Chris is editing the wiki.

   mustNotUseReservedValue is also easy, Chris is editing the wiki
   with the approach.

   mustBeInvalidated-FailDecompress: a valid font, a corrupted
   font, a woff 2 font with gzip stream (see wiki for additional
   details)

   mustBeInvalidated-FailSize: start from valid fonts and modify
   lengths (wiki edited)

   boundingbox requirement should probably just be "MUST be
   calculated" instead of "MUST be calculated at the time of
   decoding" (so that UA have more freedom in terms of potential
   optimizations)

   mustCalculateBBox: should be tested with a single glyph "PASS"
   font with no BBox.

   Vlad: questions about a CTS for Brotli itself (input files that
   must be decompressed or failing)

   David: any requirements from the IETF about this aspect?

   Chris: need to confirm

   action ChrisLilley to check expectations regarding CTF from
   IETF

   <trackbot> Created ACTION-149 - Check expectations regarding

   shouldBeShort: can't be tested but is a sound recommendation.

   <kuettel_> (3) between extended metadata and private data

   <kuettel_> vlad, chris: discussed whether there would be an
   opportunity for an exploit around private data. e.g. someone
