10/22/2015, 8:04 PMPerfect, thanks - b
bored-art-40741
10/22/2015, 8:04 PMSorry I haven't been keeping up with these - b
bored-art-40741
10/22/2015, 8:04 PMI'm interested, but I'm also knee deep in other parts of the 4sq world right now - e

10/22/2015, 8:04 PMIt probably easiest to work backwards from the examples - e
enough-analyst-54434
10/22/2015, 8:05 PMBasically, run
and see what it produces then go look at the BLD.json files in that graph./pants run src/python/pants/engine/exp/examples:viz -- tests/python/pants_test/engine/exp/examples/scheduler_inputs compile src/java/codegen/simple - w

10/22/2015, 8:33 PM@happy-kitchen-89482: well, shoot. i think i need language subsystems for this. - w
witty-crayon-22786
10/22/2015, 8:35 PMscala_platform can be somewhat abused to be the scala subsystem. but jvm_platform can't be used as a 'java' subsystem. - w
witty-crayon-22786
10/22/2015, 8:38 PMwill loop back on that later. - w
witty-crayon-22786
10/22/2015, 8:45 PM...or i just drop the idea of making the default per-language configurable. - w
witty-crayon-22786
10/22/2015, 8:45 PMand make it configurable on jvm_platform. - d

10/22/2015, 9:21 PMThis is ready to go if someone could merge it for me? https://rbcommons.com/s/twitter/r/3001/ - h

10/22/2015, 9:22 PM@witty-crayon-22786: How do you deploy pants at twitter? Build a pex? - h
happy-kitchen-89482
10/22/2015, 9:23 PMand @ancient-stone-50795: same question for Square - r
rough-minister-58256
10/22/2015, 9:25 PMwe build a pex that lives on a remote artifact store (http), then have a pants wrapper script that checks a committed version in the repo to bootstrap that when you run ./pants - r
rough-minister-58256
10/22/2015, 9:27 PMso when you run pants for the first time it looks like: - r

rough-minister-58256
10/22/2015, 9:27 PMand subsequent runs just invoke the cached pex - h
happy-kitchen-89482
10/22/2015, 9:29 PMCool, similar to what we used to do - r
rough-minister-58256
10/22/2015, 9:29 PMwhat do you guys do now? - r

happy-kitchen-89482
10/22/2015, 9:30 PMAnd you build the pex with
?./pants binary src/python/pants - b

10/22/2015, 9:30 PMIt's not actually a vend, but it's the same principle - b

10/22/2015, 9:30 PMWe create a virtualenv and install pants into it + any extra requirements for our plugins, with a
to a local mirror of our wheelhouse--find-links - r
rough-minister-58256
10/22/2015, 9:32 PMprior to yesterday we had a rather clunky pants_internal build process to integrate internal code together with oss pants. Stu has since revamped that to build oss pants and run all of our internal stuff as plugins - I’m not 100% clear on the exact details - b
bored-art-40741
10/22/2015, 9:33 PMOur plugins run as loose code, but I've tightened up our python internally sufficiently that I might change that soon and instead cut the plugins as sdists - w
witty-crayon-22786
10/22/2015, 9:33 PMyes we also use a virtualenv and internal wheelhouse - b
bored-art-40741
10/22/2015, 9:33 PMOh and I wrote buildgen for python - r

10/22/2015, 9:33 PMah interesting
