09/10/2015, 1:14 AMafaik, yeah - historically there was {PEX,PANTS,PYTHON}_VERBOSE; PYTHON_VERBOSE seems to be gone, PANTS_VERBOSE is replaced with -ldebug and PEX_VERBOSE=5 is like running ‘pex -v -v -v -v -v’ etc. - r
rough-minister-58256
09/10/2015, 1:14 AMseems there’s PEX_TEARDOWN_VERBOSE too - r

09/10/2015, 1:15 AM@cuddly-accountant-94274: are you hacking on pants these days? - b

09/10/2015, 1:21 AMI'm finding it very easy to blow the heap even on G1, and I suspect it is just in fact leaf targets with lots of classpath dependencies consuming too much analysis - b

09/10/2015, 1:21 AMEventually the nailgun dies and the task moves on, which makes it an invisible perf issue - b

09/10/2015, 1:22 AMI would much prefer that it OOM faster, but it seems to take its time doing so. G1 is running a GC about once per second, but apparently only cleaning up just enough to keep it from properly OOMing - b

09/10/2015, 1:25 AMIt sounds like you do well internally on 6gb heap (what's your perm gen?) and with 4 workers? And do you find yourself compiling "leafy" targets (with lots of potentially non-overlapping classpath dependency analysis) in parallel? - c

09/10/2015, 2:43 AM@rough-minister-58256: I wouldn't say so, not yet anyway. I'm at the point where I can build my own pex, but still having trouble with the go contrib loading simple smile I expect to have to soon though, for cgo and go linting and maybe some other stuff. - r

09/10/2015, 3:16 AMah cool - c

09/10/2015, 3:46 AMIs there a preferred OS environment for pants development where everything (pants bootstrap, tests, etc - basically ci.sh) just works out of the box without debugging stuff? (Tried Yosemite and Ubuntu 14 thus far.) - b
bored-art-40741
09/10/2015, 3:47 AMBoth of those should work, though "out of the box" is always a little conditional - b
bored-art-40741
09/10/2015, 3:48 AMI'm on Yosemite for the majority of my development though I support CentOS 6 environments as well - b
bored-art-40741
09/10/2015, 3:48 AMI can help if you're having issues - c
cuddly-accountant-94274
09/10/2015, 3:50 AMWell, I can probably debug it but it's likely irrelevant to what I need to do. Mostly just thinking about getting a cloud VM with whatever is the least painful environment. E.g. right now some pip bootstrap fails with an error message that's swallowed into a log file that is deleted by the time the error is reported, and it's just...uuuugh. - c
cuddly-accountant-94274
09/10/2015, 3:50 AMI guess if someone happens to recognize the typical cause: - c

09/10/2015, 3:51 AMYeah, that's the opening salvo of pants on OSX - c
cuddly-accountant-94274
09/10/2015, 3:51 AMOk. Apparently also on Ubuntu 14. simple smile - b
bored-art-40741
09/10/2015, 3:51 AMone sec - b

09/10/2015, 3:51 AMThere's a header lib you need to install for psutil to be able to compile its native libs on both OSes - c
cuddly-accountant-94274
09/10/2015, 3:52 AMI actually didn't have this problem on OSX. I'm on Ubuntu now since I'm trying to get a dev env up on my "private" setup, since pants contributions wants github etc and I try not to cross the streams (work and private). - b
bored-art-40741
09/10/2015, 3:52 AMIt might just be the python-devel headers? - c
cuddly-accountant-94274
09/10/2015, 3:52 AMMaybe. Checking if I"ve got them installed - b
bored-art-40741
09/10/2015, 3:52 AMThe quick check for a better error is to make a regular virtualenv and attempt to install psutil into it - c
cuddly-accountant-94274
09/10/2015, 3:52 AMBut like. This whole mess of pip/virtualenv/etc, is there some magic incancation to make them all behave in a maximally debuggable way (don't swallow errors, don't remove temporary data, etc)? - r
rough-minister-58256
09/10/2015, 3:53 AMis your compilation environment bootstrapped? what error do you see if you grab psutil sdist from pypi and run a ‘python2.7 setup.py bdist_egg’ ? - r

09/10/2015, 3:54 AMI was missing python-dev; installing that now. - b
bored-art-40741
09/10/2015, 3:54 AMI think most users of pants at this point are deploying to relatively managed environments, or at least with existing binary dependencies built for the supported environments, which is why we tend to be blind to these kinds of starter issues
