This will land in tandem with bug 1115437 and bug 1127888 which will ensure that all tests pass both with e10s and without.

Filed bug 1135130 for e10s-specific issues. Since this bug deals with riding the trains, and e10s is not yet riding the trains, e10s-specific bugs should not be blocking this one.

Backed out due to the sudden emergence of bug 1135431 when asyncInit is turned on :-(. According to try it goes orange ~50% of the time on Win64 debug.

Yes. We have it in the list in bug 1122046, bug 1131138 will take care of adding the requested prefs.

Release Note Request (optional, but appreciated)
[Why is this notable]: It will significantly improve browser responsiveness when NPAPI plug-ins are instantiated in a web page.
[Suggested wording]: Asynchronous initialization of NPAPI plug-ins has been enabled.

Enable asyncInit
Approval Request Comment
[Feature/regressing bug #]: Asynchronous plugin initialization
[User impact if declined]: Feature won't be available in 38 and will not be able to ride the trains ahead of e10s.
[Describe test coverage new/current, TreeHerder]: Flag enabled and tested extensively on try.
[Risks and why]: Moderate. Feature has been in the tree and tested for some time now. New unexpected issues may be encountered with a larger audience. It hasn't landed on Nightly yet because of e10s issues. Because this feature has a different implementation on e10s, it really needs to be activated on Aurora to be able to properly determine its effects in the non-e10s case. At the same time, we can always pref it off again if there are too many problems.
[String/UUID change made/needed]: None.

As 38 is going to be an ESR release, can we postpone that change for 39? The merge is next monday.
It is a nice feature but I don't see the point of rushing here... Especially with a moderate risk.

I'd really like to try it out now. The non-e10s case has barely seen any testing because it's been stuck on nightly. Since it is trivial to revert (by preffing off again), I'd really like to uplift ASAP.

It is too late in the 38 cycle to take a new feature or important change.
Moreover, the 38 release is one of the two major releases that we do now. I would like to avoid "noise" on this release with new features to focus on the one we have...
39 in aurora is just in a few days...

You're the release manager so it's your call, however I do protest: The fact that 38 is a "big" release is precisely why it would be really good to take this feature! Performance *is* a feature, and this particular one eliminates 1/2 of our top ten hangs. To me that is something that is worth including in a "big" release.

This is all about risk management. I agree with Sylvestre that this is not the right kind of risk to take late in the aurora cycle for 38.

Do you have any examples? If there are some issues then we need to file some bugs so I can look at them!

Bug 1121011, a dependency of this bug, may be an example. A Flash-based Japanese online stock trading system is also broken, but it's not reported yet.

I can't reproduce bug 1121011. A bug report for the latter issue would be nice.

See bug 1194833 for reproduction case where this breaks any video using Google's Flash-IMA toolkit for ads. Ads and video playback are both broken.

I don't understand why you enabled API in FF40, it's clearly still bugged, I triaged 3 or 4 new bugs about Flash apps failling to load, even famous apps like FarmVille 2 on Facebook.
IMHO, API should be disabled in a chemspill release until these bugs are fixed.
Comment 33•9 years ago

[Tracking Requested - why for this release]: This breaks various Flash content in Firefox 40, including video players, games, online stock trading system. I know 40.0.2 is already out, but this might be another chemspill driver. The risk should be pretty low, just change the dom.ipc.plugins.asyncInit pref to false as before.

I can easily tell you why: Nobody - yes, nobody at all - reported any issues with it while it was on Firefox 40 Beta, and everything that was tested by our QA engineers worked as well. So it was not "clearly" having issues. That said, it seems like this is one more piece that shows us that too few of the right people are using Beta at this time or those that are may not report their issues.

We don't need a back-out patch. If we decide we need to get this disabled for users, we can and should do this with an add-on hotfix, which does not need an actual point-release.

any plans as to when we would be rolling out the add-on hotfix for this?

None of these ended up attached to bug 1116806. If these things aren't being reported and/or the right people aren't being notified, then it's very difficult to get this right in time for release.
(In reply to Kohei Yoshino [:kohei] from comment #35)
> We need a back-out patch then.
As KaiRo indicated, we'll do this via hotfix addon if necessary. I will be engaging with the appropriate parties to come to a decision on this.

I filed bug 1195609 to track your bug. Async plugin init is supposed to work seamlessly with existing plugins without modification, provided that the plugins are correctly abiding by the API contract. In particular, make sure that your plugin is checking return codes from NPN functions.
Other than that, we're probably going to push a hotfix to disable the feature while the compatibility issues are being ironed out.
