We want the debugger server to be able to run in workers, where XPCOM is not available. To work around this, we are going to implement a CommonJS loader for workers, which does not depend on XPCOM, does not expose the chrome component to its modules, and provides any platform APIs we need as built-in modules. When running on the main thread, these platform APIs will be implemented as XPCOM components. When running on a worker thread, they will be implemented by the Worker Debugger API (see bug 757133).
The idea is that any server code that is able to run while it is being loaded by the worker loader on the main thread, will also be able to run on the worker thread. This allows us to get rid of all unnecessary XPCOM dependencies while still running on the main thread, and only then move everything over to the worker thread, which should make things much easier to debug.
To make sure people won't keep adding XPCOM dependencies to the code paths relevant for workers, I plan to refactor the xpcshell tests for those paths so that they are run twice: once for a server loaded with the devtools loader, and once for a server loaded with the worker loader.
Note that for all this to work, the code paths relevant for workers must load all their dependencies using the loader, and avoid the use of Cu.import and loadSubScript whenever possible, which makes this bug dependent on bug 859372.

Because we want to load the debugger server using different loaders, I tried to get rid of the dbg-server.jsm dependency in head_dbg.js. As it turns out, this causes strict warnings as errors to be turned on for several files. This patch fixes those strict errors.

To be able to run our tests against multiple servers, we need to make the server to be used a parameter of some of the helper functions in head_dbg.js. This patch takes care of that.

Fix strict errors in the debugger server

There is a shorter form for dealing with the annoying warnings for "foo.bar may be undefined". Instead of:

This patch refactors the breakpoint tests so that they are run against two loaders. Right now both loaders are separate instances of the devtools loader but in a subsequent patch I will replace one of them with the custom worker loader I've been working on.
I eventually want to include more of the xpcshell tests, but getting the breakpoint tests to work seems like a reasonable first step.

This patch implements the worker loader and runs it against the breakpoint tests. Note that this version of the loader still provides built-in modules that are based on the use of Components such as chrome, Services, Timers, etc. The next step will be to get rid of those dependencies for which I don't have replacement APIs on the worker side, and fix any code that breaks in the server as a result.
Note that this patch includes some minor changes to SDK code. I actually need to open a separate bug for those changes, but haven't gotten around to that yet (I'm currently stuck trying to get the SDK tests to run locally).
I've only included the SDK changes to the patch so that you can test it locally if you want to. Should you decide to r+ the patch, I will understand that to apply only to the non-SDK parts.

Implement the worker loader

Nothing serious, just a few minor comments and ideas. I like how clean and thoroughly commented the worker loader is!

This regular expression doesn't seem to work:
"foo/bar.js".match(/\.[^\\]*^/) === null
I'm guessing you probably meant to use /\.[^\\]*$/, but I still don't get the [^\\] part. Also note that this still fails for something like "foo/bar/". That is probably not important if we're going to be the only consumers of this loader, but in that case why not just write:

This seems like too much churn for such a trivial change. Why not just use default values and contain the changes to head_dbg.js? Something like:

This patch creates a whitelist of modules that are allowed to require the built-in chrome module. If a module that's not in the list tries to require chrome, it gets a vacuous object instead.
Initially, the whitelist will contain all modules that are needed for worker debugging that currently depend on the chrome module. This will help to identify what modules we need to refactor.
By maintaining a whitelist, we can remove the dependency on chrome on a module by module basis. This is desirable because we want some test coverage for this as soon as possible: any attempts to readd chrome dependencies to modules from which I already removed them should cause test failures.

You didn't undo the move of the test functions to the inner scope, which would have cut down the patch size to a minimum.

If not, I'll be happy to take another look at the updated patch.

Is that really better than throwing? It seems to me that it will lead to confusing error messages for the uninitiated.

I didn't undo them because the last test functions needs to call aCallback, which is an argument to the outer function. Simply indenting the test functions to make them part of the inner scope was less work than passing aCallback to every test function. Does that make sense, or would you still like me to do it differently?

We don't want to throw here. We want top-level code like:
const { Cu, Ci } = require("chrome");
to work inside workers, as long as you don't actually use any code paths that *use* Cu and Ci.
Compare this with the much uglier:
try {
var { Cu, Ci } = require("chrome");
} catch (e) {}
or:
if (hasChrome) {
var { Cu, Ci } = require("chrome");
}
to guard against requiring chrome in a worker. I tried both approaches, but decided against them in the end.
Also note that actually using something like Cu in a worker will give you an error like 'Cu is not defined'. That's not *too* confusing imho (assuming you'rw aware that Cu might not always be available ofc).

I would have used a global gCallback next to the existing ones, but it's not really important since the bulk of the changes were mechanical. I was mostly trying to optimize the review response time ;-)
Oh, and you are totally right about avoiding try/catch clauses for require("chrome"). I forgot about that.

Good point. It would be nice if we could lazily create xpcInspector in the loader, when the module is first required, but this is somewhat complicated by the fact that built-in modules are frozen when the loader is created.
Any suggestions to work around this?

We can't load JSM's in a worker, which means that we can't use XPCOMUtils.jsm. Since we only need 2 functions from this file, the easiest solution is to simply copy them over to DevToolsUtils.js, and require them from there.

Copy the lazy getter functions from XPCOMUtils.jsm to DevToolsUtils.js
Review of attachment 8423291 [details] [diff] [review]:
-----------------------------------------------------------------
If these are the only uses of the XPCOMUtils lazy getters that we care about, then we could do something even simpler. NetworkMonitorManager and stringBundle are used in a single location each, so we could just inline the lazy getter there (and get rid of the L10N helper). Both of these code paths are not going to be taken in a worker.
|console| doesn't seem to be used anywhere in this module and is also being preloaded as a loader global, so you should be able to simply remove it.

This patch refactors main.js to be worker friendly by removing or lazifying any top-level references to chrome. This should make this code runnable inside a worker as long as we don't use any code paths that actually require chrome.

DevToolsExtensions.jsm is needed by script.js, but as you know by know, we can't use jsm's inside a worker. Before we can refactor script.js to be worker friendly, we thus need to convert DevToolsExtensions.jsm into an SDK module.

So this makes calling createBundle eager from lazy and I think it will also happen for embeddings that don't even use DS__defaultAllowConnection. For that reason, I think it would be best to just create the bundle inside DS__defaultAllowConnection and use GetStringFromName directly, removing L10N completely. I looked at the platform code and CreateBundle doesn't do much. It's GetStringFromName that does the heavy lifting, so making it lazy wasn't buying us much anyway.

Ah, so you use the copied functions in this patch! In that case ignore my previous comment.
It seems like although small patches are easier to review, breaking them in too small bits results in not being able to see the bigger picture. Just a thought to keep in mind.

Are you sure about this? If I am not mistaken, some tests still fail when using async promises that the loader exposes by default. Make sure you get a green try run before landing this patch!

Did you get a clean test run with this patch? It looks to me like it would fail at least these:
toolkit/devtools/tests/mochitest/test_devtools_extensions.html
addon-sdk/source/test/test-page-mod.js
Also, can we move DevToolsExtensions.js to toolkit/devtools/server as it is server-side code, and call it content-globals.js?

Good catch on the test failures. I wrote that patch late at night, so I hadn't bothered to test it (what could possibly go wrong, right?) Sorry about that!

By the way, as it stands, the global cache in content-globals.js is not going to work inside a worker (we don't have Services, and we don't have Ci either). Is that going to be a problem? And if so, can we work around it?
Let's hash this out on irc tomorrow!

Turns out that protocol.js doesn't actually depend on Cu, even though it requires it, so this is a trivial patch.

The part that worries me here is that not having access to Ci will break all the object previewers in workers. How exactly are these object previewers used, and how does the observable behavior of the debugger change if they are not available?

I should also point out that Nick assured me that NetUtil won't be used on any code paths used inside workers, so simply wrapping it inside a lazy getter should be enough.

"Assured" is a little strong. I am pretty sure, but I could be wrong!
The object previewers are what are used to show
> a = { foo: 1, bar: 2 }
Object { foo: 1, bar: 2 }
instead of:
> a = { foo: 1, bar: 2 }
[object Object]
In the webconsole and the variables view sidebar in the debugger.

content-globals.js contains a few helper functions for adding content globals created by jetpack add-ons that use the page-mod API. Since workers don't have access to the DOM, that API should be unavailable there.

What Nick said. I said on IRC that we should be fine because I think the problematic previewers for workers are those that concern DOM objects, which won't be present in a worker. Fingers crossed of course.

I would avoid this line. Just use `devtools.require('devtools/server/content-globals')`; we do the same when we load custom loader for unit test, so it will be consistent with the rest of our code.

That line is there for a reason. If you use devtools.require the linker will treat it as an ordinary require and barf on it.

Note that I didn't actually change anything in this file other than its name and the way we require things. I appreciate the thoroughness of your review, but I'm not going to address style nits for code that was already there ;-)

I see. In our test case we have such code but we also requires module that are in the SDK. In that case, because `devtools` variable is not used at all except to get the `require`, you could just have:
const { devtools: {require: devtoolsRequire} } = Cu.import("resource://gre/modules/devtools/Loader.jsm", {});

I know, that's why I added in the first comment:
"Plus, you just port a previous code: usually when we do that we also trying to align the old code to the current code style, however feel free to ignore it in this specific case"

Land it in fx-team first.
Get the diff/patch, replace all of the "addon-sdk/source/" matches with "" (also remove diffs for files outside of this directory), `git apply <path-to-diff>`, `git commit -a --author="..." -m "..."`
or wait and I will do it before the next uplift.

Tests in the Jetpack tree are no longer working now that fx-team has the patch and the jetpack tree doesn't. (See https://tbpl.mozilla.org/?tree=Jetpack&rev=5c6388ee3fb1 )

Erik, can you make sure you get this synced over today so tests work again?

I wasn't quite happy with the last patch, so this patch cleans up that situation.
We still need to get rid of the dependency on Promise.jsm. I've filed a separate for that (see bug 1016301).

This seemed to fit better next to the other Cu.import statements, but oh well.

Nit: I think it would be cleaner to write this as:
let caller, func, path;
if (!isWorker) {
caller = ...
func = ...
path = ...

You should remove the .js extension.
