pantsbuild #general

@mysterious-farmer-45668 kochiku worked pretty well for us to start with. But then started breaking down with the massive amounts of test targets in our repo

and the fact that we run tests on pants changed on every PR

Hi, I'm seeing weird behavior with

test-changed

and a build

[cache]

. After having done a full compile to my remote cache,

./pants test

skips through (https://gist.github.com/MasterDDT/f87db410628af44eecdd53c01169f6b7). However

./pants test-changed --include-dependees=transitive

in the same dir seems to compile a lot of stuff (https://gist.github.com/MasterDDT/4159a783f6ab88be6e7ad38882df9fca)

I looked through the few test-changed issues, didnt see anything related.

@quiet-ice-72984 what is getting tested? Of the supported languages, only python test results are cached currently. I'll let you fill in more details before saying more.

Hmm, just read you 1st gist and pytest runs and then junit hits the cache, which is unexpected (to me). If I don't dig tonight I'll poke around the code in the morning and comment here.

enough-analyst-54434

07/24/2017, 2:49 AM

Oh, junit hits the cache for the junit runner tool used to run the tests, not for the tests themselves.

Pretty sure the

--include-dependees=transitive

picks up a different ivy resolve from otherwise, which is enough to invalidate the prior compile (code same, deps new, so have to recompile to make sure dep linkage works).

Good morning everyone!

I could really use some help figuring out a general workflow with Pants if anyone has some time today.

I'd ask the question and if anyone knows the answer and has time, they'll post an answer 🙂 some online communities don't react very well to broad notifications like that (not sure if this is one of them)

quiet-ice-72984

07/24/2017, 3:36 PM

@enough-analyst-54434 I see, yeah if

--include-dependees=transitive

is a diff ivy resolve, then that prob invalidates everything down the line, which explains the compiles? ok thanks. and yes i have py and scala tests both run, i just cut off the in the snippet, but i saw both tests run

@bright-apartment-76721 has it right @handsome-toddler-25361. In addition to avoiding at-here notifications, your question is rather broad. If you're looking to set up a CI workflow, that gets a bit more narrow and we have some experts that might respond. If your question is more about developer workflow maybe phrase in terms of I do X now with build system Y, how do I do that or something better with Pants? There are also experts in transitioning from Y to Pants that might answer.

I'm seeing some IOErrors with workunit output files and go thrift generation after upgrading to pants 1.3.0

@acceptable-kitchen-41259 probably worth filing an issue with details.

I'm trying to get pants run on jenkins.

@mysterious-farmer-45668 : to use the

virtualenv

based in install, you need:

Copy code

A C compiler, system headers, Python headers (to compile native Python modules) and the libffi library and headers (to compile and link modules that use CFFI to access native code).

mysterious-farmer-45668

07/24/2017, 9:53 PM

so am i correct in understanding that the jenkins server lacks one of those (i think the python headers)?

witty-crayon-22786

07/24/2017, 9:53 PM

so depending on your linux distribution, will need to make sure those are installed
