Hey Scott, in the future please don't leave the description blank as it makes it harder to find bugs and adds context for others who find it and may not understand what it's about. Thanks

I've changed the `gSubDialog` function so that it acts like a SubDialog manager. When `gSubDialog.open` is called, it creates a new SubDialog instance, and add/remove listeners accordingly. I also removed some promise code that handles closing timing. I don't think it's necessary anymore because closing happens synchronously now when the entire SubDialog node is removed (rather than unloaded).
The test cases don't work yet because I've changed the DOM structure. I'll update them and upload the patch ASAP.

The patch has been updated to produce a more sensible diff. Updated `browser_subdialogs.js` tests, but there are still 3 spots that are failing. Two of which are related to the page back function (which closes the dialog). I'm not sure what I did but it appears to be a focus issue.
I just noticed that there are dialog related tests in head.js and other files which I will also update.

Bug 1340987 - (Part 1) Use arrow functions in gSubDialog.

Note that you will need to make the change to in-content-old too. Same for subdialos.js I think though maybe we can unfork that file?

Instead of switching this all to be created programmatically did you consider having the "template" in the document (e.g. adjacent to the stack) and cloning it via cloneNode for each opened dialog? Similar to the idea of using <template> (though this is XUL)? That would allow this DTD string to be resolved by the parser properly.

What is the reason for removing the argument defaults values? They were there to indicate which arguments are optional. Are you wanting them to always be explicitly passed? I realize that real consumers will use the global gSubDialog.open.

Can you please try to separate this patch into separate commits since it's hard to review as-is:
* Switch to arrow functions in a few places which means changing to `this` inside
* Switching to a stack and using the SubDialog prototype.
* All of the code related to removing `unload`/`_isClosing`

Ok I'm using cloneNode on the "template" for creating new dialogs now :)

I have split up the patch into different parts. It's much more readable now!

Sorry about the mess on the initial patch. Hope it's more readable now :)
I've commented out a few test cases because I couldn't get it working still. It's about the fact that we should be able to use goBack to cancel/close a subdialog:

Hi Matt, I'm trying a different approach that will possibly reduce the amount of code change and resolve the goBack issue previously mentioned. So if you haven't got around reviewing this it's okay. I'll update the patch again soon.

Bug 1340987 - (Part 2) Make Preference SubDialog stackable.

I think the @overlay attribute should have a more semantic meaning because currently the selector for it doesn't have much semantic meaning. Is it really indicating that it's topmost? If so, use topmost="true" (XUL attributes use booleans).

It seems to me like this should be dispatched on `_overlay` so that the event target is more useful and you can use instead of assume that the close is always for the topmost dialog.

I guess this should be deleted since it's now a getter?

The distinction between these three getters isn't very clear, different names would help and if that's not enough then JSDoc comments may.

This feels a bit ununsual to me. `_lowerDialog` is always the third from the top?
::: browser/components/preferences/in-content/subdialogs.js:478
(Diff revision 2)

Why not `getElementById("dialogTemplate")`? It seems more clear and less fragile.

(Diff revision 2)
> + this._dialogs.push(new SubDialog({template: this._dialogTemplate,

Why are we pushing one at `init` time and using is as `_newDialog`? If there's a good reason it should be explained since the natural way would be to construct the subdialog just before calling its .open method
::: browser/components/preferences/in-content/subdialogs.js:527

::: browser/components/preferences/in-content/subdialogs.js:527
(Diff revision 2)
> + _onDialogClose() {
> + this._newDialog._overlay.remove();
> + this._dialogs.pop();
So this is where we actually remove the dialog element? Why don't we have to wait until the closing promise is resolved? The `_newDialog` name is confusing to me here. Should `_newDialog` be `_topMostDialog`?
It seems to me like most of the SubDialog.prototype.close code can be removed, since we don't have to worry about re-using anymore, right?

(Diff revision 2)

`_ensureStackEventListeners` is how I've seen code communicate that calling it multiple times won't cause problems. Note that I also replaced "Parent" with "Stack" since I think it's more clear.

`_removeStackEventListeners`

Why not display:none for #dialogTemplate or #dialogStack? display:none allows layout to avoid frame construction. You can use the @hidden=true (XUL using boolean attributes) instead of using styles.

Can you add 2 checks in this method:
1) that gSubDialog's array of dialogs decreases by 1
2) that the count of children of the stack decreases by 1

This is a case where the difference between `_newDialog` and `_topDialog` are important but it's not immediately clear to me that this is correct partly due to naming.
Can you explain this to me if you don't end up cleaning this up based on part 2 suggestions?

Sorry, this note was for myself. I meant to say that I think we should somehow handle close being called on a dialog which isn't top-most. The simplest would be to through an error and don't close it maybe using preventDefault?

I have removed the _newDialog getter and renamed it to _preloadDialog. The _lowerDialog is moved into the _onDialogOpen where it's used.
> Why are we pushing one at `init` time and using is as `_newDialog`? If there's a good reason it should be explained since the natural way would be to construct the subdialog just before calling its .open method
Yeah this is a bit strange. I am changing this to only push the _preloadDialog to _dialogs only when it's opened.
> Sorry, this note was for myself. I meant to say that I think we should somehow handle close being called on a dialog which isn't top-most. The simplest would be to through an error and don't close it maybe using preventDefault?
In order to allow the dialogs below to be closed, I've a few changes:
- The reference of the closed dialog is passed into `_onDialogClose`, and check if it's the `_topDialog`.
- Since the top-most dialog might not be the one closed, `_dialogs.length` could no longer be used as a ID. `_dialogID` is used instead, and it increments whenever a dialog is created.

Ideally we should be able to remove the dialog element when we close it, but a lot of tests are closely coupled to rely on the existence of the element.

I've renamed `_newDialog` to `_preloadDialog`. Hope this would make it more understandable.

I've added Part 5 which applies the changes to in-content-old, and unforked subdialogs.js, as well as fixing all the tests that are affected.

Rather than unforking subdialogs.js, it's probably better to apply the changes to the `in-content-old/subdialog.js` file.
Since `subdialog.js` references `in-content(-old)/preferences.css` and `in-content(-old)/dialog.css`, unforking it would mean we need to stick to one version of the stylesheets. It would be problematic if the styles related to subdialogs are required to be different for the new and old preferences.

`_nextDialogID`? As-is I could read it as being the ID for this `gSubDialog` instance which doesn't really make sense.

Instead of `content` can you use `gBrowser.selectedBrowser.contentWindow` (feel free to alias to a `let`) since `content` is a magical alias that may lead people to assume this code is running in a ContentTask or in the frame scope but it's running in the ChromeWindow scope.

What's this for? It may deserve a comment but I'm not sure this change is a good idea yet.

I thought about this but don't really have a good reason for separating the two, so I think I'll just move the init logic to the constructor.

> Instead of `content` can you use `gBrowser.selectedBrowser.contentWindow` (feel free to alias to a `let`) since `content` is a magical alias that may lead people to assume this code is running in a ContentTask or in the frame scope but it's running in the ChromeWindow scope.
Ok I'll do that.
> What's this for? It may deserve a comment but I'm not sure this change is a good idea yet.
I found that without it, `browser/components/preferences/in-content/tests/browser_connection.js` would crash when calling `content.gSubDialog.open`, but I haven't been able to pin point the cause of it...

I think we should debug this more. What was the stack of the crash? Did it crash locally or only on Try?

It crashes both locally and on Try. Here's a try I just did: https://treeherder.mozilla.org/#/jobs?repo=try&revision=2cb2586fb8d0f4e713cc80216ab246a77e99c403
It happens when `openAndLoadSubDialog` is used, so there are 3 tests that are affected: `browser_connection.js`, `browser_connection_bug388287.js`, and `browser_proxy_backup.js`. It crashes at calling `content.gSubDialog.open`, but the function isn't `undefined`. In the crash log is does say `Crash reason: EXC_BAD_ACCESS / KERN_INVALID_ADDRESS`. Wonder if you've encountered something similar to this?

The useful part is the stack in debug builds which are at: https://treeherder.mozilla.org/logviewer.html#?job_id=94724243&repo=try&lineNumber=4214-4254

Can you switch this to use .name instead?

The crash report points to this line: https://hg.mozilla.org/mozilla-central/annotate/a374c3546993/dom/base/nsGlobalWindow.cpp#l3993 but that doesn't make much sense to me. Can you attach a native debugger with `./mach run --debug` and set a breakpoint on that line and see what line it actually crashes on. I'm wondering if some inlining, optimization, or preprocessor is changing things a bit.

Is there a reason for the ordering of these two lines? There's a chance it's related to the crash if an XBL binding is involved.

Making a minimal test case by commenting out test and product code until it stops crashing would help narrow down the cause. It's related to openDialog and the arguments passed to it. Maybe an argument changed types and can't be handled anymore?

Here is the stack of crash, still need to find out why. For my brief skim, it seems like we hit a assertion[1] when doing window.openDialog().

Yes that could be removed.

`.name` wouldn't work here because it's not shown in the document yet.

Since John is caught up in other M3 bugs, and don't have the capacity to thoroughly trace the crash that occur in the tests. He had some ideas but nothing conclusive yet. I'm also solving bugs related to select element. Wonder if we could settle with the workaround for the time being? I've left a comment for future reference: https://reviewboard.mozilla.org/r/128970/diff/5-6/
Some test files have changed quite a bit since the mass replace of `async & await` so I tried rebase it first and pushed to try. The result seems okay: https://treeherder.mozilla.org/#/jobs?repo=try&revision=38d6ae099200bf2d99ab1b9a24035763ead1d439
I haven't pushed the rebased code because it would mess up the interdiff quite a bit.

I think the crash is simply because the openDialog code path assumes[1] that the name being passed to openDialog from chrome callers is of a frame that is ready to use but now that we dynamically append a frame it's no longer ready. A simple way to know if the <browser> binding is attached is to wait for the about:blank load event after appending. This seems to work fine and you can confirm that it's not just working now because of the Promise itself by switching to a Promise.resolve() instead... it will still crash.
If possible we should switch `open` to an async function and await on the about:blank load inside it. I'm not sure if that will cause other test failures or not though... it seems like opening is async anyways so it's probably better that way.

I'm pretty sure the problem is because the frame/browser isn't ready when we call openDialog, so simply waiting for it to be ready can fix the problem. See comment 67.

Thanks Matt, the solution you suggested works nicely. I've rebased the patches to central, and running try now: https://treeherder.mozilla.org/#/jobs?repo=try&revision=fda97fc316dd12aa89796aad5a0900d618813772
One thing I added was moving focus when opening and closing dialogs. Without it, keyboard shortcut would not work properly when dialog is closed.
