1635494 - Kill processes from about:processes

Status: ASSIGNED

(Core :: DOM: Content Processes, enhancement, P3)

Description

[David Teller [:Yoric] (please use "needinfo")]

We need a button to kill a process.

We may wish to allow both a graceful kill and a not-so-graceful one.

Comment 1

[David Teller [:Yoric] (please use "needinfo")]

I wonder if we should also have a "Pause process" for testing purposes.

Comment 2

[David Teller [:Yoric] (please use "needinfo")]

So, after discussing this on chat, the consensus is that we shouldn't try to be gentle with the content process when we kill it.

We should, however, make sure that we don't send a crash report.

Comment 3

[David Teller [:Yoric] (please use "needinfo")]

After chatting with gsvelto, it seems that a SIGKILL or a TerminateProcess should manage to kill the content process without sending a crash report.

Attachment: Bug 1635494 - nsIProcessToolsService;r?lina

A small xpcom module implemented in Rust, designed to provide low-level tools to deal with processes
from JS. For the moment, the only notable feature is kill(), designed to be used from about:processes

Services.processtools.kill() is designed to kill without causing crash reports.
Let's make sure it does not cause crash reports.

Depends on D82552

Just a utility shortcut to make using nsIProcessServiceTools more readable from JS.

Depends on D82553

This adds a new button to kill processes.

That's in a third-party library upon which I do not depend and that I do not touch in my commit, so I plead innocent on that one.

The underlying issue is... irritating.
It's a minor Rust papercut, I guess, but which turns into a build bustage.
