1091187 - Move selectionchange code in nsGlobalWindow::UpdateCommands

Status: NEW

(Core :: DOM: Core & HTML, defect)

Description

[Neil Deakin]

Bug 987040 made an unnecessary api change here and added code that doesn't have anything to do with updating commands. This should be undone and the code moved elsewhere.

Hi, I'd like to take this on as my first bug assuming its still valid.

From what I can see the affected code is here: 
https://dxr.mozilla.org/mozilla-central/source/dom/base/nsGlobalWindow.cpp#9754

Can you give an explanation of the intended function of this code and the intended function of the code to be moved?

Hi Jamie, thanks for taking this on. Some of the work for this has already been done in another bug. The remaining work is fairly simple:

1. Remove the two unused arguments from nsGlobalWindow::UpdateCommands.
2. Remove the check that looks for "selectionchange" within this method.

You'll need to change the uuid on the interface when the interface is changed. See https://developer.mozilla.org/en-US/docs/Generating_GUIDs

Otherwise this looks good.

Was this patch ready to land? Looks like this got stalled after being r+'d.

[Neil Deakin]

Yes, it should be ok, but we likely will need an updated patch.
