nbp mentions that JSCList should be killed off someday - let's write C++ instead. It is mostly still used in the js debugger. http://dxr.mozilla.org/mozilla-central/search?q=JSCList Found when JSCList caused false positives in Coverity static analysis results (based off around Oct 31, 2013).

Bug 803441 seemed more like a meta bug, and this bug seemed to be about JSCList usage in the js debugger (as per comment 0), so let's firm it up this way. (Moreover there wasn't a dependent bug on bug 803441 which mentions the js debugger)

I am in favor of this change. :)

note to self: I'd prefer using the coverity keyword to track actual issues found by coverity.

Hello!Is this bug still unsolved?I'm new to open source and I would like to give this a try.

Hi HellosAazS, and welcome! This is still unsolved, yes. A good start for working on this is probably to take a look at the remaining uses here: http://searchfox.org/mozilla-central/search?q=JSCList&path= It looks there are only a few remaining, so removing JSCList itself doesn't seem too far off. If you need any more information, set the "Need more information from" checkbox and enter ":erahm" in the text input next to it so Eric gets notified. Otherwise, once you have a patch attach it here and set the "review" flag on the attachment, again with ":erahm" in the text input that'll appear next to the checkbox.

Will do.Thanks for the help!

Hello, Eric! I'm new to here and I'm trying to solve this bug. I've tried to read source code of Debugger(which use JSCList) and LinkedList in http://searchfox.org/mozilla-central/search?q=JSCList&path= . But when I want to modify the code, I found that I lost in the thousands lines of code and don't know where to start and what to do first. I know this question is somewhat stupid, but I've never work with open source before, please forgive me! Could you please guide me a little or give me any clues? That will be helpful and thank you in advanced! (P.S.:This is the first time I use Bugzilla,so I don't know whether this comment is inappropriate or not.If it is,please let me know and please accept my apologies!)

(In reply to HellosAazS from comment #8) > Could you please guide me a little or give me any clues? Of course! This bug sounds pretty simple, we ideally want to convert the usage of |JSCList| [1] to |mozilla::LinkedList| [2], but it turns out it's a bit tricky as we seem to want to hold these elements in multiple lists and |mozilla::LinkedList| doesn't support that. I'll layout what lists we have below and loop in a JS engine expert to help us sort this out. First we can see the usages from searchfox are limited to js/src/vm/Debugger.cpp, js/src/vm/Debugger.h, and js/src/vm/Runtime.h [3]. So hopefully that's a little less intimidating. From what I can tell there three lists remaining: #1 - JSRuntime::onNewGlobalObjectWatchers_ [4] This holds a list of |js::Debugger| instances. We can see that |js::Debugger| is already a |LinkedListElement|, which is both a good thing and a bad thing. This means it's already held in a separate linked list and we'll need to figure out how to manager that. #2 - Debugger::breakpoints [5] This holds a list of |js::Breakpoint| instances. We would want to make |js::Breakpoint| implement |LinkedListElement| like so: > class Breakpoint : public mozilla::LinkedListElement<Breakpoint> But there's a catch, as the next list also wants to hold the same breakpoints. #3 - BreakpointSite::breakpoints [6] This also holds a list of |js::Breakpoint| instances. Jim do you have any thoughts on how HellosAazS should proceed?

Thanks, these info help me a lot! I'll focus on these parts while waiting to know if Jim has any suggestions!

Hi, Eric!I think Jim haven't reply this.Do you have any suggestions on how I should proceed? Or do you think I should find another bug until there's more information?

It might be a good idea to switch to another bug while we wait for jimb to respond. You might be interested in a similar, but more straightforward bug 1357155 in the meantime. Thank you again for your interest in contributing!

Sorry to be slow to reply. I can see why this might have been marked as a "good first bug", but having looked it over, I'm not sure it is. I think Debugger happens to be a complicated use of a usually simple feature. As Eric points out, JSCList allows nodes to be inserted in more than one list at a time, whereas mozilla::LinkedList does not. So Debugger is not a situation where we can simply replace the one with the other. The linked list management for breakpoints is pretty hairy, and unless you're quite comfortable with C++, this probably just isn't a good place to start. It's possible to replace Debugger::onNewGlobalObjectWatchersLink and JSRuntime::onNewGlobalObjectWatchers_ with something like a mozilla::Vector, but that would mean that removal would change from a constant-time unlink operation to a scan of the vector, linear in the number of Debuggers. That's probably fine in almost all realistic circumstances. But this, too, requires a pretty solid understanding of pointers and lifetimes in C++. HellosAazS, take a look at that and if it looks straightforward, If we had bug 1277725, that might change the situation a bit.

Thanks for your explanation! I think this is a little complex for me as I don't familiar with the codebase now. I'll still give it a try and hope that if I could find the way to solve this.

Clearing mentor flags, this isn't a good first bug.

It wants to do pointer comparison (this == toFind), the auto loop would give a ref. I guess we could & that. I don't care much either way.

(In reply to Eric Rahm [:erahm] (PTO May 4 - 8) from comment #31) > ni for comment 30. Le sigh, that test isn't right. If the element is the only element in the list it's mNext is null and it's mPrev is null. I'll look at this again tomorrow.
