Re: [webkit-dev] JavaScriptCore Debugger - Non-Browser Implementation
Hi, The APIs exist, so it should be possible to make one, but no one has done so at this time, so far as I know. We did implement a remote debugger in JSC in Wakanda Server. It will be open-sourced very soon. For a quick demo please take a look at this video: http://www.wakanda.org/blog?page=2 -Sergiy Temnikov Wakanda Server architect Message: 4 Date: Mon, 13 Feb 2012 11:39:52 -0800 From: Maciej Stachowiak m...@apple.com To: Matt Veenstra matts_li...@tribalmedia.com Cc: WebKit Development webkit-dev@lists.webkit.org Subject: Re: [webkit-dev] JavaScriptCore Debugger - Non-Browser Implementation Message-ID: f2261cff-e25e-41cd-8f71-c001c4db6...@apple.com Content-Type: text/plain; CHARSET=US-ASCII On Feb 7, 2012, at 10:18 PM, Matt Veenstra wrote: Hello, I am looking for a tool to help debug JavaScript code for JavaScriptCore when NOT using a browser?

Re: [webkit-dev] Remote debugger
OK, cool! Thanks a lot. Nice to see a functioning browser to browser debugging. Do you know if the Web Inspector protocol specification is stable and finalized now?

Some information on the protocol and is outlined in the following links. I don't think they are up to date; I think things have improved and evolved since then. Pavel and Ilya may be able to comment more on the protocol since there has been quite a bit of work recently splitting it up into different domains to turn on/off debugging different domains or feature sets. But I think the protocol has been stable for a while. I think they even had some discussion with the Firebug team when they talked about a debugging protocol, but I can't seem to find where that discussion took place. http://webkit.org/b/43732 Web Inspector: Remote debugging meta-bug https://docs.google.com/document/edit?id=1d_N-OIb3UztuC-_g0piXsIIdp89HnMcDk-uSQ8uamW4hl=enauthkey=CIf48O4Jpli=1#https://docs.google.com/document/edit?id=1d_N-OIb3UztuC-_g0piXsIIdp89HnMcDk-uSQ8uamW4hl=enauthkey=CIf48O4Jpli=1 Here is a screencast, previously posted to this list, of it working in Chromium: https://lists.webkit.org/pipermail/webkit-dev/2010-August/013797.html http://screencast.com/t/YTI2OTY4YTEt There has been some work on an internal WebKit solution based on Web Sockets: http://webkit.org/b/43988 Web Inspector: Remote Web Inspector support for QtWebKit [Already Landed] http://webkit.org/b/51364 Web Inspector: Remote Web Inspector - Cross Platform InspectorServer [Open - Issues to be Worked Out] External to WebKit, Patrick Mueller has been working on weinre.

Re: [webkit-dev] Remote debugger
Hello, I have not been on the calls but I have posted about my remote debugger work on the FireBug working group message board. It is true that Crossfire is smaller than the Web Inspector protocol but it has all I need for the remote debugging of a faceless server that runs JavaScript. In fact the two protocols are quite close to each other, at least the part related to the source code inspection and tracing. I might even support both seeing that it does not require too much work to reformat messages from one protocol to another. I wish the two protocols were unified and compatible :-) -Sergiy [cid:f9ed10.png@1aafdebe.4b9b52d9] Sergiy Temnikov Architecte Logiciel Email : sergiy.temni...@4d.commailto:sergiy.temni...@4d.com Web : www.4D.comhttp://www.4D.com 4D SAS 60, rue d'Alsace 92110 Clichy - France Standard : +33 1 40 87 92 00 De : Patrick Mueller [mailto:pmue...@gmail.com] Envoyé : vendredi 18 février 2011 20:08 À : Joseph Pecoraro Cc : Sergiy Temnikov; webkit-dev@lists.webkit.org; Pavel Feldman; loi...@chromium.org Objet : Re: [webkit-dev] Remote debugger Hello Sergiy, Have you been on any of the FireBug working group calls? Wondering if John J Barton and Michael Collins (like me, they also work at IBM) are familiar with your work. I join the calls occasionally, just to keep up to speed with CrossFire, and don't remember hearing from you - but I also don't pay a whole lot of attention during those calls :-) My understanding is that CrossFire really only supports JS breakpoints at the moment - if you look at the protocol that Web Inspector uses, you'll see it's quite a bit larger. In addition to everything Joe mentioned, there's a guy who has Web Inspector hooked up to node.js for doing source-level debugging with node with the WI front-end. https://github.com/dannycoates/node-inspector - I keep meaning to get in touch with that guy, but haven't yet.

[webkit-dev] WebKit on the server side
Hi, We are working on a new application server that uses WebKit for server-side JavaScript execution (and remote JavaScript debugging too). However, we can not use WebKit as is because we can not link with any of the GUI libraries and WebKit does. Instead, we compile just the JavaScriptCore part for JS execution. So my question is, are there any plans in the future to refactor or redesign WebKit to be more suitable for server environment? Would this, in your opinion, interest the WebKit community? For example, the first thing we had to deal with is the JS debugger. Debugger interface is defined in JavaScriptCore but its implementation lives in WebCore. Most of the debugger's implementation is abstract except for the part which sends event notifications to pages and frames objects which are GUI dependent and so can not be used in a faceless server application. So we basically copied the source of the existing debugger, commented out GUI related calls and added some stuff to transform it into a debugger which can be controlled remotely over the network. I would be happy to contribute to the WebKit project to add a layer of abstraction to the existing debugger implementation to cut its dependence on GUI and move it to JavaScriptCore from WebCore's inspector. Another example would be the XMLHttpRequest class implementation which exists in WebCore. In many indirect ways it depends on GUI even though it should not. As such, we can not simply expose it in our JavaScript environment on a faceless server. There are many other classes like it. All in all, so far it has been great fun to make the WebKit code run on the server side. I just wanted to raise awareness of the needs of server-side developers. -Sergiy Temnikov, Wakanda Server Architect Wakanda Software ___ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
