wohali commented on issue #2345: port to spidermonkey 60 URL: https://github.com/apache/couchdb/pull/2345#issuecomment-564816138 Hi @jiangphcn , this is a big PR and it's taking me a bit of time to work through. While I'm doing that, I went and had a look for pre-built versions of SM60. libmozjs-60 is available pre-built only on: * Debian buster (10.x) and newer. * Ubuntu disco (19.04) and newer - but no LTS releases past bionic (18.04LTS) exist yet. @willholley so far I cannot find libmozjs60 precompiled for _any_ version of RHEL/CentOS, is this true? This probably means that for the rest of our binary build matrix, we'll have to start building libmozjs60 and distributing it ourselves, as we do today for the ancient 1.8.5 library. That means building it for: * Debian stretch (9.x) * Ubuntu xenial (16.04LTS) * Ubuntu bionic (18.04LTS) * CentOS 7 * CentOS 8 * Windows 64-bit I'm intentionally excluding CentOS 6 from that list because it will go End-Of-Life on November 2020; people stuck on it can live with 1.8.5 a little longer, I think. 😉 The alternative is that we only ship our binaries with 60 in them only for Debian buster, and maybe Windows (tech preview), then add in the other platforms over time, as packages materialise (or if we decide to pick up the slack). Perhaps we know someone over at RH/CentOS who can get a mozjs60 package released for CentOS 8 at the very least... The good news is that the Docker container can probably be moved from stretch to buster fairly easily (there was a single bug outstanding against ppc64le, which may actually be a qemu bug) so our Docker users can enjoy the new support with this release. What do you think?
