1101478 - Remove the WindowsJumpLists.jsm depedency on hasHistoryEntries

Status: RESOLVED FIXED

(Firefox :: General, defect)

Description

[Marco Bonardo [:mak]]

The hasHistoryEntries usage there is not very mandatory.

the optimizations we make for the empty history case may affect a very minor percentage of users (permanent pb) for which the queries would be fast already.

The clear history on shutdown would be better served by doing an update on clear history, more generally.

Marco, please add this to the current iteration.

I haven't set up review board yet and have no idea how to work with it. I'll look into that but if you're interested in quick turn around time please post a normal dif for review.

You don't have to setup anything, just enter the link with your user/password for bugzilla, go to the "diff" section and it basically works like Splinter. When you are done adding comments, go to the "reviews" section, choose publish and mark the Ship it! check box if it's a plus.

I actually had your same doubts when I got my first request with RB, but it took just a few minutes, not much different than Splinter.

in case of doubts, this should help with the UI:

I can't seem to get the splinter interface working. you have white space cleanup you need to do in one spot.

[Marco Bonardo [:mak]]

just clicking once on the line NUMBER should allow you to add a comment through a popup (And that opens an issue for me to fix).

Btw, found the spot, thanks.

Thanks. I think I was clicking on individual lines expecting a splinter inline comment panel to appear. Will try the line number trick next time.

All in all, looking forward to working with this.

Backed out on inbound for suspicion of causing the spike in bug 1103966.
https://hg.mozilla.org/integration/mozilla-inbound/rev/8e5fce59af55

I'll back this out from Aurora as well once it's confirmed fixed on trunk.

I'm unassigning this cause the benefit is almost nonexistent atm, while investigating the shutdown crash could take huge effort.

It's basically not worth it now.

Comment 19

[Mike Conley (:mconley) (:⚙️)]

BHR / arewesmoothyet.com indicates that there are a non-zero set of users experiencing hundreds of milliseconds worth of hangs with hasHistoryEntries on the stack due to main thread IO. I think we should revisit this.

Comment 20

[Marco Bonardo [:mak]]

The backout issue may be gone in the meanwhile, I just never had a chance to check if this still causes bug 1103966.
Apart from the NetUtil usage the original patch should still apply.

Comment 21

[:Gijs (he/him)]

P2 to at least investigate per the previous comments.

Comment 22

[Marco Bonardo [:mak]]

I'm re-testing the patch on Try.

Comment 23

[Marco Bonardo [:mak]]

I retriggered it a ton of times on Try and didn't see any crashes
