[Edbrowse-dev] js shell

[Edbrowse-dev] js shell

[Karl Dahlke]

Again, wondering why edbrowse works with our compiled js 24 library
but not with their distributed library.
Has anyone looked at their shell application?

/usr/local/mozjs-24.2.0/js/src/shell/js.cpp

If you take this stand alone program and compile it
against the debian library does it run?
If not I would think that worthy of a bug report.
If yes then there is information there.

I did a grep for NewRuntime
and there are only a couple calls between that and NewContext,
which is the point where we segfault.
I don't think the intervening calls are important,
although SetNativeStackQuota might be,
don't know what that does.

Well it seemed like something to look at,
an application that they provide, that uses their library,
that is suppose to work.

It isn't quite standalone, as it uses headers private to mozjs, some of
which are autogenerated.  I can't seem to get it to build without
building the whole libmozjs.
On Debian, the libmozjs source is intertwined with the source for
iceweasel, which is basically their rebranded firefox.  So in order to
build the js shell, I have to build a whole web browser!
Or at the very least, I need to get through its ./configure phase.
Unfortunately, that's going to require installing a bunch of development
packages for GUI libraries, and my VM disk image just doesn't have enough
space for that.

They do package the JS shell, and it works fine,
but it is statically linked against Spidermonkey.  IMHO, that isn't a
good test of whether the dynamic libmozjs library is working properly.

A better question is this.  Do they have any package that does link
against the libmozjs dynamic library?
Yes they do.

So presumably all of that stuff that depends on xulrunner -- and
indirectly on libmozjs -- works just fine.  Can we conclude that their
package doesn't have a bug and we're doing something wrong in JS
initialization?
