Spidermonkey 1.8.5 is deprecated

[aelmahmoudy]

Spidermonkey 1.8.5 has been removed from Debian, because it is unmaintained and has a security vulnerability. Could elinks migrate to mozjs-52 or mozjs-60 ?

[rkd77]

I updated code to mozjs-17.0. Is this version maintained in Debian?

[aelmahmoudy]

Debian only has mozjs-52 & mozjs-60

I tried building that commit (after patching confgure.ac to use mozjs-52), but configure script reported that Spidermonkey is found but not usable.

[aelmahmoudy]

I patched configure.ac by inserting: AC_LANG_PUSH([C++]) [...] AC_LANG_POP([C++]) around the AC_LINK test, and it passed. Yet the build failed, since the code is in C and the mozjs lib is using C++ constructs.

[aelmahmoudy]

Couldn't this be done by adding a C wrapper around mozjs library instead of converting elinks' complete code to C++ ?

[rkd77]

I don't know C++ nor SpiderMonkey. In the future it is possible, but not now.

[doughdemon]

I'm looking into porting to newer versions of SpiderMonkey by compiling only the src/ecmascript and src/scripting/smjs directories with C++. This might work, though is not completely ideal because the mixture of C and C++ produces many type conversion warnings.

[rkd77]

I would rather switch to QuickJS . It is C and has smaller memory footprint, but first I want to finish libdom "migration". I stopped on tables. JS is rather next year, not now.

I see, that makes sense. (QuickJS does look similar to old Spidermonkey.)

[aelmahmoudy]

Unfortunately QuickJS is not available on Debian

[niutech]

Can't you use the Mozjs C API?

[rkd77]

I spent too much time on SpiderMonkey to give up now. It compiles with mozjs52, but segfaults. I have no idea yet, how to resolve it. If you know, please write it here, or prepare a patch. Usually it related to threads. js::PerThreadData::runtimeFromMainThread (this=0x0) or JS_AbortIfWrongThread(cx).

[niutech]

According to the NEWS file, elinks 0.15.0 now uses mozjs78-dev or QuickJS-2021-03-27 for ECMAScript support. So can we close this issue?

[doughdemon]

sounds good to me.

[MagicalDrizzle]

so currently you have to use mozjs78 correct? cause if yes then I wasted way too much time compiling mozjs17 oops

[rkd77]

yes, either mozjs78 or quickjs, but do not expect too much.

[raekuul]

just as a heads-up: I had installed libmozjs-78-dev on a Debian Testing system and it was not detected by the configure script. The same system also has libmozjs-91-dev installed so it might be a package conflict.

[rkd77]

You need also libsqlite3-dev and libxml++5.0.1.GIT or higher. I doubt libmozjs-91-dev has any influence on build process. And add CC=g++ to ./configure invocation. meson builds are faster.

[holtzermann17]

Hi, just to update: I got it to build with recent libmozjs (revising to package=mozjs-102 in the configure file). I had to bring in some dependencies like this:

PKG_CONFIG_PATH="/opt/netsurf/pkgconfig:/opt/netsurf/inst-gtk2/lib/pkgconfig/" ./configure --with-spidermonkey --enable-256-colors

Configure reports:

...
checking for SpiderMonkey (mozjs-102) in pkg-config mozjs-102... yes
...
ECMAScript (JavaScript) ......... SpiderMonkey document scripting
...

The build completes successfully. However, even though I have the ECMAScript option turned on in elinks, when I go to https://www.whatismybrowser.com/detect/is-javascript-enabled, it tells me that it's not enabled.

Edit: I tried with quickjs instead, and still the site didn't detect Javascript enabled!

[rkd77]

Besides examples in test directory, none of real scripts are operational. I want to "migrate" from libxml++ to libdom first, to be able to copy more code from netsurf. Progress is slow. js is postponed. The plan is to gradually make to work some scripts like a js terminal emulator, searching in Python docs, and playable tetris, but the first milestone I want to achieve is functional background colors in documents.

[andrewp907]

What is the current status of enabling JavaScript support on elinks on Debian?
