test suite for jsd?

John J. Barton — 2008-11-02T17:27:34

Are there tests for the 'jsd' layer of the debugger api? If so where are they hiding? Thanks, John.

Debugging stand-alone JS apps

Harald Krapfenbauer — 2008-10-29T14:39:06

Hello, There are several Eclipse JS debuggers around (e.g. in the Eclipse ATF project) which use the jsdIDebuggerService interface, but they all require XPCOM and run the debugger inside the Mozilla framework. Since Spidermonkey is able to run without the Mozilla framework too, I was wondering if it would be feasible to debug a JS application that runs from a simple Linux shell? Best regards, Harald

interactive session

I can't type anything into the interactive session, its as though the keyboard is disabled anyone got any ideas or is it a bug, am using running Venkman version 0.9.87.4 with Firefox 3.0.3

Re: Firebug internals discussion?

John J. Barton — 2008-09-30T04:18:25

http://groups.google.com/group/firebug The signal to noise ratio on this group is high: mostly my posts and spam. My proposal is to discuss 'jsd' and internal aspects of firebug. Of course others may choose to bring up the topics you suggest. Three people from Mozilla work on Firebug. The group here is mozilla.dev.apps.js-debugger, not .venkman.

On 05.08.2008 03:27 John J. Barton wrote Yes, I would. Simply, because it should be possible to ask the admins to create a 'mozilla.apps.firebug' group. That way one can safley assume, that the messages one wants to browse belong to the software s/he is using. We get overdrawn by information these days, it would be nice to have some pre-filtering by keeping newsgroups at a low signal-to-noise ratio. Imagine topics like these: - Can't get things to work! - Debugging stops halfway in my code and hangs. - Please help a newbie - etc. So our good reader opens these, reads into it, just to realize, that it was about Venkman and not about Firebug (or vice versa). As it is, Venkman still seems to be the semi-official js-debugger for Mozilla code, so this group should stay for Venkman. If any of the admins in responsibility are reading this, may I kindly ask you to think about a 'mozilla.apps.firebug' group, since I would like that one, too. I would appreciate that.

jsdIStackFrame scope jsParent

John J. Barton — 2008-09-16T05:35:18

A Firebug user just told me about "jsParent". This is a property of jsdIValue objects and it turns out that if the jsdIValue object is jsdIStackFrame.scope, then the jsParent is a link to the scope chain for the function on the stack. Is there any way to get this scope chain from a jsdIScript object? Its a property of the function not the stack correct? jjb

isLineExecutable() very slow.

John J. Barton — 2008-08-20T03:20:26

Just a little tidbit from Firebug experience: jsdIScript http://www.xulplanet.com/references/xpcomref/ifaces/jsdIScript.html has a method, PRBool isLineExecutable ( PRUint32 line , PRUint32 pcmap ) Based on some very informal measurements I found that it takes about 1ms per line to call this method. When you apply that to 40k lines, not much goes on for while. I don't know if this is intrinsic or just because of crossing in and out of C++ but it would be good to understand so we can create a faster next gen API. For example we could replace this with Array executableLines(pcmap); for most applications. jjb

Proposed changes to jsdIDebuggerService and friends

John J. Barton — 2008-08-15T16:56:05

Please take a look at Modernize jsdIDebuggerService https://bugzilla.mozilla.org/show_bug.cgi?id=449452 for links to several bug reports outlining improvements in jsd. Of the possible ways to proceed, I am inclined to push for Bug 379410 – debugger script detection using parent JSScript or if this is too hard, then a limited version of Bug 449454 – [jsd] Add frame argument to every jsd callback, eg jsdIScriptHook John.

Richard, might I ask what the objection is?

Yes. Richard

Re: Firebug internals discussion?

Justin Wood (Callek — 2008-08-08T19:53:32

Given that this is m.d.a.js-debugger and not .venkman sure, it fits. And furthermore as a user of both venkman and firebug I do prefer firebug of the two anyway, so the conversations will likely be enjoyable.

Re: Seamonkey 1.1.9 gets glacially slow after opening JS debugger

Peter Weilbacher — 2008-06-26T06:12:00

Hmm, it doesn't happen to me. I take it that you have tried to at least restart SeaMonkey afterwards (and perhaps also reboot the system)? I have no idea what could be causing either the initial delay when starting the JS Debugger nor the subsequent slowness when loading pages. AFAIK that tool doesn't have platform specific parts, so this might not be tied to OS/2. I'm cross-posting this to mozilla.dev.apps.js-debugger to get input from people who actually know that tool.

How to open Venkman with a given file?

Is it possible to programatically open Venkman with specified file (chrome url) opened by default, which is also automatically scrolled to a given line? Honza

Re: jsdIFilter?

John J. Barton — 2008-06-11T20:04:36

Thanks for your information. Unfortunately the only case I really need is scriptHook :-(. The big overhead in Firebug is caused because the only way to sort out scripts is to have a stack and scriptHooks do not have a stack. So I have to take the scriptHook and set a breakpoint to get a stack. I thought I could pay back some of the overhead if I could filter scriptHook calls to focus only on the ones that need processing. John.

Venkman has a mini-example/test in http://mxr.mozilla.org/seamonkey/ident?i=cmdTestFilters. No guarantees on its stability, though, as I don't know of anything that actually uses it (besides that mini-test in Venkman). Would be great if you can report back on if it works, doesn't work or takes down the world in a ball of fire. ;)
