They can jump straight to the end result and skip intermediaries. We can't have nice things with the 30+ year old tool that is GNU Make. Well, we could, it just require us to invent a build mode that short-circuits compilation, linking, etc and manually fetches the final object from the cache. IMO we should build this for Firefox and Firefox OS developers. We kinda/sorta already have this in xulrunner and parts of Firefox OS builds. We know the approach works. We just need to make it turnkey and better integrated with release automation. Are there any bugs on file with more details about the work needed to get this kind of high level cache for Firefox and/or Firefox OS? As you say, this would dramatically improve build times for front end changes that don't involve C++ at all. If this is too OT for the thread, please ping me on IRC. I'd like to help drag this forward if I can.
There may be a bug on file. I can't remember. But any forward progress on this front requires the deep involvement of a build module peer or someone who has intimate knowledge of the build system, its intersection with automation, and to some extent version control. I may have more fingers on one hand than people who have enough up-to-date context to formulate an optimal solution.
If we want progress on this front, those people need to meet next week and draw up battle plans. Furthermore, we need commitment from our respective managers that this should be a priority sometime in 2015. Even if we can't get a commitment to work on this, I think drafting up a plan to get there is worth spending time on.
I'm build module owner. I'll try to assemble something. _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
