Why does Roboto not display in Firefox Nightly? #738

sucrose · 2017-04-26T13:41:18Z

I receive these errors in the console on my Windows 7 system using Firefox 54.0a2 (2017-04-26) (64-bit):

downloadable font: Layout: DFLT script doesn't satisfy the spec. DefaultLangSys is NULL (font-family: "Roboto" style:normal weight:normal stretch:normal src index:2) source: http://fonts.gstatic.com/s/roboto/v16/CWB0XYA8bzo0kSThX0UTuA.woff2 css:50:12

This happens when gfx.downloadable_fonts.otl_validation is set to true (the default for Nightly but not stable releases)

The text was updated successfully, but these errors were encountered:

cesarbruno16 · 2017-06-19T08:18:20Z

there's soluction to this problem?

m4rc1e · 2017-06-19T10:37:42Z

I'm not able to replicate this with Firefox 55.0b2 (64 bit).

I'm guessing Mozilla changed the settings for OTS sanitizer in 54.0a2 and have now reverted them back.

scheinercc · 2017-06-19T12:24:52Z

It is fine in 55 (macOS; beta/dev) indeed, though the issue still there in current nightly (v56). Default setting for gfx.downloadable_fonts.otl_validation in v55 currently is 'false' while in v56 it is (still!?) 'true'.

wisniewskit · 2017-07-22T03:28:41Z

Only the nightly Firefox builds specifically should have gfx.downloadable_fonts.otl_validation set to true by default, whereas betas (including dev edition) and stable versions do not.

scheinercc · 2017-07-22T14:40:26Z

Maybe @sucrose can change the title to "Roboto not displaying in Firefox Nightly (gfx.downloadable_fonts.otl_validation set to true)" or similar?

davelab6 · 2017-07-23T21:07:41Z

OpenType spec v1.8.2 released recently (http://typedrawers.com/discussion/2276/opentype-1-8-2-released#latest) which changes the spec to make this valid.

davelab6 · 2017-07-23T21:08:34Z

The solution is going to be for OTS to be updated by @khaledhosny to reflect the latest spec, and for that to trickle down to Firefox.

davelab6 · 2017-08-11T19:44:16Z

The solution is going to be for OTS to be updated by @khaledhosny to reflect the latest spec, and for that to trickle down to Firefox.

Per khaledhosny/ots#131 and https://bugzilla.mozilla.org/show_bug.cgi?id=1331797#c29 I was wrong about this; we now see Nightly has the latest OTS (https://github.com/khaledhosny/ots/) but the problem persists, and Khaled has confirmed that OTS should not be changed to allow the error. (Also, I found the overall rationale for using OTS is in https://bugzilla.mozilla.org/show_bug.cgi?id=964696#c5)

So, since the fonts imported into the Google Fonts API are valid, and OTS is valid in rejecting the fonts exported from the API, the issue lies with the https://github.com/fonttools/fonttools subsetter which the GF API uses. I hope someone at Mozilla can provide a patch.

davelab6 · 2017-08-11T22:17:11Z

@behdad has fixed the underlying problem in the fonttools subsetter -
fonttools/fonttools@6eb807b - so when the fonttools copy used by the GF API is updated, Nightly should stop barfing :)

Thank you Behdad!!!

jfkthame · 2017-09-27T16:19:58Z

We're still seeing invalid Roboto resources served by Google Fonts; e.g.

downloadable font: Layout: DFLT script doesn't satisfy the spec. DefaultLangSys is NULL (font-family: "Roboto" style:normal weight:100 stretch:normal src index:2) source: http://fonts.gstatic.com/s/roboto/v16/2tsd397wLxj96qwHyNIkxHYhjbSpvc47ee6xR_80Hnw.woff2

Any chance the fix could get deployed sometime soon?

davelab6 · 2017-09-27T18:33:17Z

Soon! :)

scheinercc · 2017-10-01T13:23:50Z

FYI, Roboto is working for me in Nightly 58.0a1 (2017-09-30)

When I load all fonts, I get the error "Native load test failed:" for these fonts:

Pangolin
Philosopher
Sedgwick Ave
Sedgwick Ave Display
Sedgwick Ave
Sedgwick Ave Display
Cabin Sketch
Kurale
Bellefair
Londrina Solid
Londrina Shadow
Londrina Sketch
Baloo Tammudu

jfkthame · 2017-10-01T14:32:59Z

I didn't check all of these, but at least the first few seem to have a different problem than the missing defaultLangSys that was the problem in Roboto:

behdad · 2017-10-01T15:56:41Z

downloadable font: Layout: Lookup flags require GDEF table, but none was found: 8

That's BS. The spec is clear that GDEF glyph classes may be automatically synthesized.

I suggest we stop wasting Google's and Khaled's time and resources on fixing this crap of a code that is GSUB/GPOS/GDEF in OTS and let Firefox do whatever they want. They apparently have not been caring enough to fix the code themselves or just disable it as it should be.

@khaledhosny I suggest you remove that code from OTS. Jonathan can maintain a fork if he wants.

This is my last comment on this matter.

jfkthame · 2017-10-01T18:33:48Z

downloadable font: Layout: Lookup flags require GDEF table, but none was found: 8

That's BS. The spec is clear that GDEF glyph classes may be automatically synthesized.

According to https://www.microsoft.com/typography/otspec/chapter2.htm, under LookupFlag bit enumeration: "IgnoreBaseGlyphs, IgnoreLigatures, or IgnoreMarks refer to base glyphs, ligatures and marks as defined in the Glyph Class Definition Table in the GDEF table. If any of these flags are set, a Glyph Class Definition Table must be present."

That's what OTS is implementing here, AFAICS. Is there another part of the spec that contradicts this? If so, please point it out, as we should ask for the inconsistency to be resolved in the spec.

scheinercc · 2017-10-01T19:38:12Z

@davelab6 @jfkthame if someone else can confirm that Roboto is working in Nightly I guess we can close this bug and rather reopen new ones for the above accordingly!?

wisniewskit · 2017-10-01T19:45:18Z

@scheinercc, unfortunately, I just tried loading the Google Fonts Roboto page with a completely fresh profile with today's Firefox nightly, and it's still not showing any text (I get the same "Native load test failed:" messages on that page) :(

A CDN propagation issue, perhaps?

scheinercc · 2017-10-01T19:57:42Z

Ah, interesting. @wisniewskit thanks for checking!
I thought if it loads on the main page, it would generally load, but I can see the characters are missing (and the error appearing in the console), even though I can see the preview text - until I use a character like "è" or "ē", than even the preview fails with additional error messages.

khaledhosny · 2017-10-02T20:43:02Z

This only affects Firefox Nightly, right? Beta and Stable already disable OTS sanitizing of OTL tables.

jfkthame · 2017-10-02T21:09:20Z

Right.

@englishextra Firefox 54 is obsolete and was superseded by 56; please always keep it current.

@fitojb

Firefox 54 is obsolete

Are you serious? It's of Jun 29, 2017

please always keep it current.

What?

wisniewskit · 2017-10-08T22:44:11Z

@englishextra, I certainly won't stop you from running old versions if you'd prefer, but it is generally unsafe to run browser versions older than the latest one (even ones that are only a few months old). You can see the known vulnerabilities fixed in version 55 here and version 56 here.

Beyond that, let's please not hijack this thread anymore about this topic, folks.

englishextra · 2017-10-08T22:48:54Z

Hey, I'm doing webdev, and I know that regular users, that I'm writing sites for, use ancient browsers. I do have Nightly and the whole zoo of browsers. I gave an info as of FF 54 - which is in my case the benchmark version of FF. That's it and nothing alse more.

55 here and version 56 here.

That's what I came here for, to make sure the sanitize error is not on my side as a web dev.
Thanks

davelab6 · 2017-10-18T23:32:25Z

This should now be fixed

wisniewskit · 2017-10-18T23:54:19Z
