The goal of this bug is to introduce a new Application panel. Guidelines: - panel should use react - panel should be off by default (and not visible in the DevTools options if possible) - panel should use localization mechanisms but the new localization files should *not* be picked up by localization teams, as we expect the strings to be updated frequently in the beginning (see Bug 1408368 for an example) - panel should only show the list of service workers (no filtering, this will be handled in a separate bug) - list of service workers shoudl be read only

Some additional context for the reviews: - the panel is preffed off for now. You can enable it with devtools.application.enabled (e.g. `./mach run --devtools --setpref devtools.application.enabled=true`) - my intention is to focus on the initial code for the panel here. I intentionally left out localization and tests (Bug 1450073 and Bug 1450071). I can fold that in if needed. - when testing, service worker debugging normally only works at the moment in "single child process" e10s. As opposed to about:debugging where we check if service worker debugging can be used, here we assume debugging "should work" before the panel is shipped. You might want to force single e10s by setting dom.ipc.multiOptOut or by using about:debugging#workers - the panel currently shows all workers (eg exactly the same list as about:debugging#workers!). Showing only the workers for the domain (or page) will be done in Bug 1450064

Comment on attachment 8965479 [details] Bug 1445197 - part 4: Implement application panel UI to display all workers; https://reviewboard.mozilla.org/r/234204/#review240040 I have mainly nits and questions here, but this looks like a solid start :) Happy to r+ this since you have tests on your todo list ::: devtools/client/application/index.html:11 (Diff revision 1) > <head> > - <script src="chrome://devtools/content/shared/theme-switching.js"></script> > + <link rel="stylesheet" type="text/css" href="resource://devtools/client/application/application.css" /> > </head> > <body class="theme-body" role="application"> > <div id="mount"></div> > + <script src="chrome://devtools/content/shared/theme-switching.js"></script> nit: would it make sense to have this script file here in part1 patch ? **Really** not important though ::: devtools/client/application/initializer.js:25 (Diff revision 1) > +// Inject to global window for testing > +window.store = store; > +window.actions = actions; or maybe we could expose them through methods on Application (`getStore`, `getActions` )? Not feeling strongly about this though ::: devtools/client/application/initializer.js:52 (Diff revision 1) > > - render(app, this.mount); > + await this.updateWorkers(); > + }, > + > + async updateWorkers() { > + let client = this.toolbox.target.client; looks like we can use `this.client` here ::: devtools/client/application/src/components/App.css:5 (Diff revision 1) > + .application { > + height: 100%; > + padding: 0 0 0 20px; > + overflow: auto; > + display: flex; > + flex-direction: column; > +} Lately I tried to make sense of "complex" layouts (flex, grid) in css files by adding ascii visualisations of what it should look like (see https://searchfox.org/mozilla-central/rev/d0413b711da4dac72b237d0895daba2537f1514c/devtools/client/themes/webconsole.css#706-722 or https://hg.mozilla.org/try/diff/e976bc9e281c/devtools/client/themes/webconsole.css#l1.14 ) in order to make it easier for contributors to know what to expect. here it might make sense to do so (even more I'd say because we don't know which children .application has since they're declared in separate css files) ::: devtools/client/application/src/components/Worker.css:13 (Diff revision 1) > + > +.service-worker-container { > + margin-bottom: 20px; > + width: 100%; > + max-width: 600px; > + box-sizing: border-box; should we put the `box-sizing: border-box` on `*` in App.css so we don't have unexpected behaviour when introducing new elements ? ::: devtools/client/application/src/components/Worker.css:17 (Diff revision 1) > + max-width: 600px; > + box-sizing: border-box; > + position: relative; > +} > + > +.service-worker-container > div { maybe this is a bit brittle ?

It feels a bit strange when accessing the store to have `state.workers.workers`

Comment on attachment 8964976 [details] Bug 1445197 - part 1: Create an application panel for DevTools; https://reviewboard.mozilla.org/r/233708/#review240630 I gave the patch a try (note that it needs rebase after accessibility panel landed), it seems to work great but I always get a broken debugging with this exception: console.error: (new TypeError("form is undefined", "resource://devtools/shared/base-loader.js -> resource://devtools/shared/fronts/device.js", 53)) ::: devtools/client/application/initializer.js:46 (Diff revision 2) > + render(Provider({ store }, app), this.mount); > + > + this.client.addListener("workerListChanged", this.updateWorkers); > + this.client.addListener("serviceWorkerRegistrationListChanged", this.updateWorkers); > + this.client.addListener("registration-changed", this.updateWorkers); > + this.client.addListener("processListChanged", this.updateWorkers); Note about perf: You are calling updateWorkers in various events which may fire frequently. getWorkerForms is called from updateWorkers and spawns various RDP requests: - listServiceWorkerRegistrations and listWorkers - but also listProcesses and for all returned content processes: getProcess, listWorkers. I don't think that's something to worry about in the first iteration, but definitely something to keep in mind. ::: devtools/client/application/src/components/WorkerListEmpty.js:37 (Diff revision 2) > + } > + > + openAboutDebugging() { > + let { toolbox } = this.props; > + let win = toolbox.doc.defaultView.top; > + win.openUILinkIn("about:debugging#workers", "tab", { relatedToCurrent: true }); Brian just added an helper module to more easily open links: https://searchfox.org/mozilla-central/source/devtools/client/shared/link.js ::: devtools/client/definitions.js:444 (Diff revision 2) > } > }; > > +Tools.application = { > + id: "application", > + ordinal: 14, Looks like accessibility panel won for #14 ;) ::: devtools/client/definitions.js:455 (Diff revision 2) > + tooltip: "Application", > + inMenu: false, > + hiddenInOptions: true, > + > + isTargetSupported: function(target) { > + return true; Do you really aim to enable this panel on all toolboxes? Shouldn't you disable it from the browser toolbox (target.chrome)? from the addon toolbox (target.isAddon)? Or only enable it for common toolboxes (target.isLocalTab)? Right now, it is displayed into SW toolboxes, which looks unexpected.

Should we wall this attribute "serviceWorkers"? Also, `registrations` isn't used in this changeset. It looks like an internal for this method and not something to export. ::: devtools/client/shared/workers/worker.js:154 (Diff revision 1) > + return { registrations, workers, mergedServiceWorkers }; > +} > + > +module.exports = { > + debugWorker, > + getWorkerForms, I'm not convinced about the location of this code. Do you have plans about this new "devtools/client/shared/workers" folder? getWorkerForms typically looks like a Front method. Now, root actor is still an old fashion actor and has an old fashion client. May be it is better to put such code there: https://searchfox.org/mozilla-central/source/devtools/shared/client/root-client.js#30 Or is it introducing too much worker specifics in RootClient? Regarding debugWorker, gDevToolsBrowser has been an historical choice for toolbox opening: https://searchfox.org/mozilla-central/search?q=.showToolbox(&case=false®exp=false&path=devtools-browser.js We get code related to all common toolbox opening (selectToolCommand/toggleToolboxCommand) and content process toolbox. Now, if you plan to have more worker related code, it may make sense to have this new folder.

Other panels (webconsole, netmonitor) use the same pattern, so I think I will stick to this for consistency. I agree about the added value of keeping filenames in sync with Classes, but in this case my vote would be towards renaming the files. > nit: Maybe add some jsdoc ? Sure. I quickly described the role of the panel, but I didn't write a detailed description as these things tend to go out of sync quickly. > If I read the code well, I don't think Application#destroy is async.

Thanks for the review Honza! Just added a comment, and interestingly it made me realize something. I guess we could have a simpler structure for this panel. Splitting the init code between panel.js and initializer.js mostly makes sense if we need to support Launchpad on top of the regular dev workflow. I'll keep it for now, but maybe we can simplify later.

As discussed I agree that the path devtools/client/application is somewhat confusing and introducting a "panels" level in the hierarachy would make it much clearer.

Ok to move debugWorker to devtools-browser (maybe a dedicated module with an explicit name would be nice) I don't like devtools/client/shared/workers either :) I want to obviously share this logic between about:debugging and the application panel, because it has some complexity. On the other hand I'm not sure if all the workarounds we have at the moment will stay after the multi-e10s sw refactor. That's the main reason I wanted a separate file here. Although it could have been a worker-utils.js in devtools/client/shared rather than having its own folder. I will move it to root-client for now. I really don't know what name to pick though. Maybe listAllWorkers with a comment to explain how it differs from listWorkers?

Just trying > to see if this should be logged as a different bug or should block this one. Actually seems like service worker debugging is broken right now. I am guessing debugger v32 with https://github.com/devtools-html/debugger.html/pull/5761 broke it ...

Comment on attachment 8965479 [details] Bug 1445197 - part 4: Implement application panel UI to display all workers; https://reviewboard.mozilla.org/r/234204/#review240040 > or maybe we could expose them through methods on Application (`getStore`, `getActions` )? > Not feeling strongly about this though That sounds good, I didn't add the getters yet since they are test only. I will add them together with the tests! I moved the creation of `store` and `actions` to the bootstrap method. They are now stored on window.Application (let me know if I should keep them out, I tested quickly and didn't see any issue but you never know!) > Lately I tried to make sense of "complex" layouts (flex, grid) in css files by adding ascii visualisations of what it should look like (see https://searchfox.org/mozilla-central/rev/d0413b711da4dac72b237d0895daba2537f1514c/devtools/client/themes/webconsole.css#706-722 or https://hg.mozilla.org/try/diff/e976bc9e281c/devtools/client/themes/webconsole.css#l1.14 ) in order to make it easier for contributors to know what to expect. > > here it might make sense to do so (even more I'd say because we don't know which children .application has since they're declared in separate css files) Sounds like a good idea! Gave it a try both here and in Worker.css. > should we put the `box-sizing: border-box` on `*` in App.css so we don't have unexpected behaviour when introducing new elements ? Good catch, that should be defined in application.css once and for all. > maybe this is a bit brittle ? Could we add a classname to this div we want to style, and here replace the rule with `.service-worker-container .the-super-div` ? I can actually just move it to .service-worker-container here i think. I will do that for now, but feel free to push back! > here, instead of passing the whole toolbox, could we only pass an openAboutDebugging function in the props, that the render function will be able to call ? > This way we keep props the to the minimum amount of things needed (which can also make component testing easier) Sure. will make testing easier. Reused a "serviceContainer" approach similar to what the console does. > maybe we could make this an `<ul>`, and either create the `<li>`s in workers.map here (and return an array from the Worker component), or make the worker component top-element (`.service-worker-container`) an `li` ? Done (worker component returns a li) > I wonder if this could be misleading in some way (like we are trying to create actual workers). Maybe we could rename it WorkersState or something ? renamed to WorkersState > nit: could we name it `list` or `all` or something else than `workers` ? It feels a bit strange when accessing the store to have `state.workers.workers` Sure, renamed to list.

It is especially useful to do that when you click on `Debug` while a toolbox is already opened. Instead of focusing the toolbox *and* switching to the debugger, it will only focus the toolbox. ::: devtools/shared/client/root-client.js:166 (Diff revision 2) > return this.request(packet); > }, > > /** > + * Retrieve the service worker registrations currently available for the provided > + * DebuggerClient. for the provided DebuggerClient => for this client? ::: devtools/shared/client/root-client.js:239 (Diff revision 2) > + /** > + * Retrieve all service worker registrations as well as workers from the parent > + * and child processes.

As mentioned to :ochameau and :jryans on slack, there is an issue with the current approach when it comes to: - hitting breakpoints in service worker scripts - getting the accurate status of the service worker To retrieve service workers we call listWorkers both: - on the Root actor - on all the ChildProcess actors And to get child process actors we call https://searchfox.org/mozilla-central/source/devtools/server/actors/root.js#524-527 . This is guarded by `if (!DebuggerServer.allowChromeProcess)`. For about:debugging this is true, but not for a regular toolbox. The consequence is that the application panel is not aware about the worker instances running in content processes. If you start a service worker manually (with the Start link), a worker will now be returned from the Root actor's listWorkers method (?). It can be used to open a Toolbox, and will show the correct sources, but setting a breakpoint will never break as expected. I am not sure how to proceed. I doubt we want to set allowChromeProcess to true for all toolboxes, or remove the limitation on getProcess. Maybe introduce a new dedicated API on the root actor that would return all workers, not blocked on allowChromeProcess? [Note that this works almost by "chance" for about:debugging because we first grab the WorkerActor from the RootActor and override it with the correct one from the ChildProcessActor.]

I imagine we are going to sync with fission work as I get to understand that the client is going to connect to many target at ones, these targets could be these workers living in other processes. So I would like to hear from :jryans here first before looking into your suggestions.
The main security concern with `allowChromeProcess` as I understand it is ensuring the user has opted into allowing _remote_ debugging of chrome processes. Looking at the main vectors that start remote servers: * GCLI listen[1]: Tied to devtools.chrome.enabled * --start-debugger-server[2]: Requires devtools.chrome.enabled = true (a bit strange, but good enough) Both remote paths create separate loaders and servers, so they are isolated from whatever choices we might make about local debugging. Given this info, I think we can safely change `target#makeRemote` to set `allowChromeProcess = true` for `isLocalTab`, which seems like it will solve the issues you are hitting. (Also, as part of Fission I am planning a new discovery mechanism for things like workers, so I'd rather not and something temporary here unless there is a strong need for it.)

Thank you both for your replies! I will log a separate bug to set allowChromeProcess to true in makeRemote().

Can we use variables or is this a common practice in DevTools? We generally use variables for things that need to change depending on the style or platform. I believe this is consistent with the rest of DevTools, which doesn't necessarily make it right. A RFC would probably be a good fit for a proposal related to this. > This diagram is a very nice touch! Suggested by Nicolas, but I agree :) > Could we use a unitless value here? to avoid this scenario: https://developer.mozilla.org/en-US/docs/Web/CSS/line-height#Prefer_unitless_numbers_for_line-height_values Sure, switched to 1.5 > how is this going to work with long names? will they break? I guess we'll have to test/adapt in the future Good point, for now we just have "Source" and "Status" but in other locales this might go over 60px. To be safe for now let's switch to min-width: 60px; > What does this message mean? It sounds a bit "too technical", did you mean "Service Workers which are not running cannot be debugged?" Yes. I wanted to keep the sentence consistent in its structure with the other log "Running or inactive service workers can not be started", but it's true that "Non-running" is hard to grasp.
