1138384 - (enable-writing-mode-release) enable CSS writing-mode support in release channels

Status: RESOLVED FIXED

(Core :: Layout, defect)

Description

[Jonathan Kew [:jfkthame]]

+++ This bug was initially created as a clone of Bug #1099032 +++

Bug 1099032 will enable writing-mode support by default for developer channels. We intend to hold back from enabling it on release channels until more CSS layout features are properly vertical-enabled; those bugs should block this one.

Attachment: Enable CSS writing-mode support for all channels

Once we land the various table-layout patches that are currently in flight, I think we're in good enough shape to do this.

What about flexbox and the underline stuff?

Comment 3

[Daniel Holbert [:dholbert]]

Flexbox is largely already logicalized, and I've got work-in-progress patches to finish it off. (once I finish with my reviews) 

(Not sure what the underline stuff is.)

Bug 1111955. The default position of underline is not very right for Japanese. The problem is that there is a pending issue on the spec, which doesn't seem to be clear yet.

Probably that shouldn't be a blocker of this bug, since our behavior currently matches that of all other browsers. Although we probably want to fix the eventually, it could happen later.

As an interim solution, pending spec finalization, this has been fixed in bug 1175789. So I don't think we need to block on it here.

As with all feature-enablings, we should be open to backing this out on release channels (and punting for a release), if we uncover any serious brokenness [particularly on real sites] without an easily-backportable fix.

r=me with that in mind.

Yes, definitely.

Pushing to inbound, in the hope it'll merge to central sometime before the uplift...

Comment 10

[Jean-Yves Perrier [:teoli]]

I've updated https://developer.mozilla.org/en-US/Firefox/Releases/41#CSS
and the compat table
of the logical properties, writing-mode and text-orientation (but not text-combine-upright)

Comment 11

[Florian Bender]

Release Note Request (optional, but appreciated)
[Why is this notable]: better l10n/i18n support for the Web
[Suggested wording]: Implemented CSS3 Writing Modes
[Links (documentation, blog post, etc)]: (MDN see comment 10)

Comment 12

[David Baron :dbaron:]

I think this should go in the documentation it's already in (comment 10), but should not be in the release notes unless we have a coherent policy for choosing which developer-facing things go in the release notes.  Instead, the release notes should point to the developer documentation that we already have and is quite thorough.

Comment 13

[Ritu Kothari (:ritu) (Inactive, please n-i to RyanVM, jcristau, or pascal)]

Since this is already in the developer notes for FF41 here: https://developer.mozilla.org/en-US/Firefox/Releases/41#CSS, we do not need to add it to FF41 release notes.

Comment 14

[Daniel Holbert [:dholbert]]

I think that means this bug should be marked as "relnote-firefox:41+",though, right? (not "relnote-firefox:-)

According to [1], relnote-firefox:- means "this bug does not meet the bar for inclusion in release notes", whereas relnote-firefox:41+ would mean "Drivers have determined this bug will be included in Firefox41 release notes."  It seems like the latter is correct.

Daniel, AFAIK, there are two different sets of release notes. 
1) https://www.mozilla.org/en-US/firefox/releases/ and, 
2) https://developer.mozilla.org/en-US/Firefox/Releases

RelMan team (including me) work on 1) and use relnote-firefox flag to track which bug fix makes into which release version notes. The developer notes 2) are managed by MDN folks and I think they use dev-doc-needed keywords.

Comment 16

[Daniel Holbert [:dholbert]]

Thanks -- I don't think that quite addresses what I was asking. I wasn't talking about dev-doc-needed or any MDN-related stuff. I'm asking about "relnote-firefox" and making sure that "-" is actually correct here.

The Release Management wiki page that I linked to in comment 14 describes the definitions of the various "relnote-firefox" values, and it seems to differ from how you set that flag here -- if that page is no longer correct, could you or someone else update it to reflect the current semantics?  (Or, if the wiki page is indeed correct, then I think perhaps this bug should actually be "relnote-firefox:41+"?)

Comment 17

[Ritu Kothari (:ritu) (Inactive, please n-i to RyanVM, jcristau, or pascal)]

Daniel, that page was updated (revamped) about 2 months ago by me. :) I do not see the inconsistency. However, I will update that page to mention that if a note is included in MDN and also nominated for FF release notes inclusion, it will be denied and relnote-firefox will be set to "-".

Again, this bug does not meet the bar for inclusion in release notes for FF41 and therefore relnote-firefox set to "-". The reason it does not meet the bar is because we do not want to copy MDN developer notes into FF release notes. Hope that helps!

Comment 18

[Daniel Holbert [:dholbert]]

Ah, I see -- I mistook the link in comment 13 as being an actual release notes link. That makes sense now -- thanks!

That would be great & would help clarify this for future folks who may be confused like I was -- thanks!
