Add new package Mozilla JS-24.2.0

[thomas]

​http://ftp.mozilla.org/pub/mozilla.org/js/mozjs-24.2.0.tar.bz2

Is that a successor of the currently used mozjs17.0.0 ?

[Fernando de Oliveira]

Yes, it seems to be a successor. But it is clearly stated that there are API differences. I am studying that since today.

[Fernando de Oliveira]

They have no common file or directory. Installed it, then DEST installed the two packages in BLFS linked to mozjs and their libraries are still linked to version 17.0.0, if linked at all to mozjs (thanks again for scanelf, Igor).

Have the tendency to say that having the two versions installed is not a problem for the system, but newer is useless for BLFS, at this stage.

Will wait for more opinions, but I am thinking of closing this ticket as invalid.

[thomas]

Do the packages fail to compile/link when only 24.2.0 is on the system? Btw, I know polkit is using JS, which is the other one?

[Fernando de Oliveira]

Packages: polkit and Gjs.

Today, tested only polkit. Configured with 24.2.0, "make" fails.

[Armin K]

Ticket is perfectly valid in the same way as BlueZ-5.x and OpenJPEG-2.0.0

You just have to wait for software to get ported to use it.

According to gjs git log, it has been alredy ported to use MozJS-24.0.0 and it will be default in next Gjs stable release (1.40.x or whatever)

​https://git.gnome.org/browse/gjs/log/

As for Polkit, no sign of MozJS-24.0.0 support yet but I guess it will be available with next GNOME release.

[Fernando de Oliveira]

Thanks finally for some comment, Armin.

[Fernando de Oliveira]

Now, we have a problem. Polkit is still the same, but gjs-1.40.0 needs mozjs-24.2.0.

Is this a case when two versions of a package need to coexist in the book?

[Fernando de Oliveira]

Adding as a new package JS-24.2.0 (/trunk/BOOK/general/genlib/js2.xml) seems to be the only solution. Polkit-gnome is still at 0.105, as is polkit, and this needs js-17.0.0.

Word of warning, I cannot build libpeas with js24 installed. Both js17 and js24 are installed. I've searched far and wide for a solution to no avail. This is the only reference I could find ​http://comments.gmane.org/gmane.comp.gnome.devel.announce/359

To save you a bit of time if you haven't started already. With js24 I needed to set 'SHELL=/bin/bash' (in chroot) and the following at the end:

find /usr/include/mozjs-24/            \
     /usr/lib/libmozjs-24.a         \
     /usr/lib/pkgconfig/mozjs-24.pc \
     -type f -exec chmod -v 644 {} \;

[Fernando de Oliveira]

Thank you very much, Wayne.

It is really a problem. We cannot update GNOME without js24. So, I think that all agree with that. But we cannot update with it, because libpeas is necessary.

I cannot use the dev machine at the moment, so later will see that new problem (and probably ne ticket!).

Will search a bit more.

[Wayne Blaszczyk]

Apologies for hijacking the ticket but it looks like libpeas 1.10.0 has just been released.

Overview of Changes in libpeas 1.10.0 ====================================

• Remove support for gjs-based Javascript plugins
• Misc bugfixes

Will let you know how I go.

[Wayne Blaszczyk]

Raised Ticket 4882. Confirmed that libpeas 1.10.0 fixes issue with JS24.

[Fernando de Oliveira]

Thanks.

[Fernando de Oliveira]

Before I forget:

many xml variables are named js2 or JS2 or libmozjs2, as well as the xml file: js2.xml

tried to keep in the readable text JS, instead of JS2

svn copied from js.xml (almost un update), so I believe setting props is not necessary, please tell me if it is

Please, tell me if I need to modify anything.

I would like to thank to all that contributed to this ticket resolution:

Thomas, Armin and Wayne.

Sorry, Thomas for having closed by mistake, thankfully corrected by Armin.

Wayne, particularly has done a big part of the page. I forgot to add two things: Remember the user that it can be installed alongside version 17.0.0, and 'SHELL=/bin/bash' (in chroot)'.

[Fernando de Oliveira]

I think it is fixed at r12921.

Will close tomorrow, if there are no comments/suggestions/fixes.
