** Description changed:
Availability
Ubuntu is a bit ahead of Debian here but the mozjs packages are maintained in
Debian. I have an ITP filed (#860396) to maintain this with the Debian
pkg-gnome team since I don't think anyone else wants the burden of maintaining
it.
Built for all supported architectures.
Rationale
=
Required by gjs (LP: #1683989) which is required by GNOME Shell. Beside
gnome-shell, gjs is also used by these apps which might be in a default Ubuntu
install.
* gnome-characters
* gnome-documents
* gnome-maps
* gnome-sushi
* gnome-weather
Security
mozjs38 is Firefox's SpiderMonkey JavaScript engine. Therefore, it gets lots
of CVEs (not all Firefox CVEs affect mozjs but there are several that do).
https://www.mozilla.org/en-US/security/known-vulnerabilities/firefox-
esr/#firefoxesr38.8
Here's how things have improved in the past 6 months though. GNOME 3.22
was still using mozjs24 which is several years out of date. For GNOME
3.24, Philip Chimento (the gjs developer) ported to mozjs31 and then
mozjs38. He currently expects to finish the port all the way to mozjs52
for GNOME 3.26 https://bugzilla.gnome.org/781429 . Although it's too
early to make a definitive decision, I think there's a good chance we
will ship GNOME 3.26 in Ubuntu 17.04. mozjs52 corresponds with the
current Firefox ESR release.
Until now, Mozilla didn't really handle Spidermonkey releases very well,
doing one release per ESR cycle. mozjs is now being built as part of
Mozilla's regular builds so I think we'll be able to get them to do
regular releases too.
Each ESR is supported for about one year:
https://www.mozilla.org/en-US/firefox/organizations/faq/
We no longer install the /usr/bin/js binary.
For 17.04, I updated the package to use the last Firefox 38 ESR as its
base (LP: #1683103)

Upstream build tests are being run now using dh_auto_test. Failing tests
do not fail the build on arm64, ppc64el, and s390x until we handle
https://bugzilla.mozilla.org/1357593
No autopkgtests.
Partly because of how old mozjs38 is, we build with autoconf2.13 and
have several patches. Hopefully, those won't be needed with mozjs52.

Background information
==
Of course, there's a Long Term Support problem with this package.
Red Hat Enterprise Linux has begun working around this issue by fully
upgrading the GNOME stack periodically. (RHEL 7 shipped with GNOME 3.8;
7.2 updated it to 3.14. GNOME 3.22 might come later this year.
Most other GNOME LTS distros (like Debian and SUSE) don't upgrade mozjs.
I expect we will be able to drop mozjs24 from the archives before 18.04
LTS. The developers of the packages using it are working on porting to
mozjs38 now. Maybe they can port to mozjs52 before 18.04 LTS too.
