We want to get the photon animation patches landed in nightly before their scheduled release in 57. We'll use a preference and a CSS class on the window root element to occlude these changes while the pref is off.

No need to qe-verify this as verification of this pref will come with verification of other animation features that make use of the pref.

(In reply to Sam Foster [:sfoster] from comment #0) > We'll use a preference and a CSS class on the > window root element to occlude these changes while the pref is off. This would mess with these rules' specificity. Please use ifdef instead.

As :dao points out, we'll run into selector specificity issues if we use a class on the root element to selectively apply photo-animation -specific rule. The only other option is a %define, and %ifdefs in our CSS, JS etc. There doesnt seem to be a practical way to accomplish what we need at runtime. The idea here is that usage will be like: # in your mozconfig: mk_add_options MOZ_PHOTON_ANIMATIONS=1 # usage .some rule { original: value } %ifdef MOZ_PHOTON_ANIMATIONS .some rule { photon: value } %endif This allows us to get this work into the tree and test the aggregate ahead of the 57 release. Once nightly becomes 57, we'll remove the %defines and %ifdefs.

It seems I need to add this new flag to a configure file as well for this to stick. I'm not clear if I should by using set_define or project_flag. And which moz.configure file it should live in? It looks like there maybe a Right Way to do this which I'm not clear on. I'm going to push a new version of the patch - think of it as a straw-man.

Comment on attachment 8861201 [details] Bug 1358215 - Add a flag to permit early landing of photon animation changes ahead of 57. https://reviewboard.mozilla.org/r/133156/#review137420 This needs some changes, but I think you can get what you want with very little work. I'm going to be PTO tomorrow so if you want a followup review before next week ping another build peer (glandium is on vacation, so chmanchester, gps, or mshal are all good choices). ::: browser/base/moz.build:47 (Diff revision 3) > > DEFINES['MOZ_APP_VERSION'] = CONFIG['MOZ_APP_VERSION'] > DEFINES['MOZ_APP_VERSION_DISPLAY'] = CONFIG['MOZ_APP_VERSION_DISPLAY'] > > +# photon animations: Nightly-only and unless explicitly disabled > +if (CONFIG['NIGHTLY_BUILD'] and not (CONFIG['MOZ_PHOTON_ANIMATIONS'] is 0)) : kinda nit-picky, but the convention we use for `CONFIG` entries is just to treat them as boolean, since they're actually either `1` or unset, so this should just be: ``` if CONFIG['NIGHTLY_BUILD'] and CONFIG['MOZ_PHOTON_ANIMATIONS']: ``` ...but really you should make `MOZ_PHOTON_ANIMATIONS` get set automatically for `NIGHTLY_BUILD`, I'll cover this below. ::: browser/moz.configure:12 (Diff revision 3) > imply_option('MOZ_PLACES', True) > imply_option('MOZ_SERVICES_HEALTHREPORT', True) > imply_option('MOZ_SERVICES_SYNC', True) > imply_option('MOZ_SERVICES_CLOUDSYNC', True) > > +set_define('MOZ_PHOTON_ANIMATIONS', False) So: a) `set_define` is equivalent to setting something in `DEFINES`, but globally. If you only need the define in one place just use `DEFINES` in moz.build like you're doing above. If you need it globally then you'll want to keep this, but... b) You need to define an option somehow. The simplest way is to use `project_flag`, like: https://dxr.mozilla.org/mozilla-central/rev/0b77ed3f26c5335503bc16e85b8c067382e7bb1e/toolkit/moz.configure#507 . That even has a `set_as_define` option if you want the define as well. Look at `MOZ_ANDROID_CUSTOM_TABS` for an example that defaults to true for nightly only: https://dxr.mozilla.org/mozilla-central/source/mobile/android/moz.configure#42 .

Thanks for the detailed answer here. I'm going to push an updated patch using project_flag. The one thing I'm not clear on is how I'll tell people to disable this option for their nightly builds. I was thinking one would just mk_add_options MOZ_PHOTON_ANIMATIONS=0 to the mozconfig file, or even just use an env. variable when building: MOZ_PHOTON_ANIMATIONS=0 mach build, but it looks like I'll need to add an imply_option('MOZ_PHOTON_ANIMATIONS', False) somewhere?

Oh, ugh. Per bug 1257326 comment 12, this was an explicit design decision of `project_flag`. :-/

We'll need this in browser code too, so I suspect toolkit/moz.configure is not the right place for this. While you're at it, would you mind adding MOZ_PHOTON_THEME too for the work under bug 1325171?

> We'll need this in browser code too, so I suspect toolkit/moz.configure is not the right place for this.

I don't know what's needed there, but if it's just a simple build option/define like this then it should be easy enough to do.

I can't say I really *understand* the lint test failure there, but the thing it's complaining about is the function defined inside `delayed_getattr`. I changed the patch to add a separate `is_nightly` function and use that, and it passes the lint check now.

chmanchester gave r+ over IRC for the updated patch, and I filed bug 1363811 to find out if the lint test is doing the right thing.
