but there are some examples as well: examples/src/thrift/org/pantsbuild/example/precipitation/BUILD

...that might not be the best example. but the keywords are

provides=setup_py(..)

Hey guys, I'm jumping on the train of building a cache server for pants, and am running into some problems. I have setup a simple nginx server with dav enabled. When I try to compile something, I get these errors:

objc[30554]: +[NSValue initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
objc[30555]: +[NSValue initialize] may have been in progress in another thread when fork() was called.

I checked the packets and do see the server respond with 404s when the file requested by the GET does not exist, and assumed pants will then build the artifacts and attempt to write it back. But it doesn't seem to even get to the compilation part before hitting these errors. A quick google search says this error has to do with some multithreading restriction with osx? Any thoughts? I'm running osx 10.14 (mojave), running Pants 1.11.0. I have the read and write url set to be the same in

pants.ini

for the

[cache]

block

My CI improvements are ready for review, in case you’re curious: https://github.com/pantsbuild/pants/pull/7047

Hey everyone! I’m new to pants and I would like to use it in a monorepo that also contains rust code. On the website I see that pants dosen’t support rust yet. Are there any plans to add support for rust in the near future?

Hey Twitter folks, how would I go about getting Pants to use the newest master version of twitter commons? Kris helped me to merge a PR that fixes a deprecation warning (https://github.com/twitter/commons/commit/ba6453e26fcb6560406f366d0c8012ab2e1cf24f), and now I’m trying to figure out how to get this into Pants Does someone need to do a release to PyPi?

as a matter of curiosity, i know some projects (often gnu projects) tend to keep per-file copyright notices up to date for the current year. i actually appreciate our policy of keeping the copyright date at the year the file was introduced as a low-key form of historical record that persists across renames (which is also useful for copyright purposes). i have also seen (and made the mistake myself) of copying over the heading from another python file when making a new file and accidentally using a year before the current one (case in point -- every one of my PRs this year so far). would it be useful to add a pre-commit check that extends the current file header check to ensure any new files have the correct year?

Hi

Is there something like bazels genrule in pantsbuild?

rerunning the bootstrap shards in travis cause other shards to fail, TIL

would be good to help clean that up. Benjy invested a bunch of time

@fancy-queen-20734 why did you rerun? I would expect the rerun to only cause problems if both runs were completely successful...

I had a failure on my run that didn’t make sense, so I was trying things to see what might fix it

the error from trying that was very clear though

Is the failure that multiple versions of the pex are detected on S3?

is there / should there be a way to pass in a set of files in a global option that pants tasks can elect to filter their input by? i'm thinking of how to make the pre-commit check faster and i don't think there's currently a way to tell python checkstyle to only lint e.g. staged files (which might significantly reduce the runtime) -- see https://github.com/pantsbuild/pants/issues/7068#issuecomment-453807593

broke out https://github.com/pantsbuild/pants/issues/7070 for this and labelled it with

good first issue

if anyone's feeling frisky

that's a great ticket number

Is there a way to override the artifact name generated for the “publish” goal. Current set of override arguments seems to be ignored. Command I am using

PEX_VERSION=1 ./pants publish.jar -ldebug --override=com.foo.bar#baz=0.1.2 --doc-scaladoc-combined=false --doc-javadoc-combined=false --publish-jar-transitive=false --publish-jar-override="com.foo.bar#test-sj=1.0.0" --publish-jar-dryrun=false --force=true src/jvm/...

Thanks

Some context: All of our code base is not in the monorepo. One of the utility in the monorepo needs to be published to artifactory. I would like to suffix commit_hash and build number to the artifact name. Couldn’t figure out how to do it. Thanks!

What’s the difference between cache_key’s and fingerprints? The cache_key contains the fingerprint? +plus something else if I remember correctly. Trying to understand the differences/unions between the 2 values below.

versioned_target.cache_key.hash.split(-1)
versioned_target.target.playload.fingerprint()

a target's fingerprint isn't transitive into its dependencies... but a cache key might be, depending on the task that created it

I have some more questions about building python wheels out of pants targets. so say I have two libraries that I want to expose for external, non-pants usage: src/python/my_org/foo/bar, and src/python/my_org/baz. I build both wheels. the first will contain a package my_org.foo.bar, and the second will contain a package my_org.baz

this isn't relevant to anything and it's not that "useful" per se but i've been wanting to get this PR in for a while, it also deprecates

stable_json_hash()

which probably shouldn't affect anyone at all https://github.com/pantsbuild/pants/pull/6475

I'm trying to clear duplicate warnings from a

jvm_binary

target. I'm addressing some by using

Duplicate.CONCAT_TEXT

or

Skip()

, which works when looking inside the jar, but the "dup" task is still outputting them to be a duplicate. Looking at the task code it doesn't seem to take any JarRules into account. Is there a proper way of telling pants that these have been addressed for a specific target (I don't want to globally ignore specific things as they might not be addressed in new/other targets)? Examples of what I'm looking at which I think would be pretty common: *

META-INF/INDEX.LIST

and

META-INF/io.netty.versions.properties

from Netty *

reference.conf

from Akka

what CI are you using with pants ?

@enough-analyst-54434 I don’t appear to be able to run pants from source outside of the pants repo any more, and I used to be able to… If I run with

PANTS_DEV=0

I get told

Could not satisfy all requirements for pantsbuild.pants.contrib.python.checks.checker==1.14.0.dev1:

and if I don’t, I get told “Path “contrib/python/src/python/pants/contrib/python/checks/checker” does not contain any BUILD files.” - any idea what I need to do about this?

made a native code github project if anyone likes c/c++ and wants to see what's happening: https://pantsbuild.slack.com/archives/CB8F24LPM/p1548220846000600

having a form of

./pants list

which also prints the stringified targets sounds extremely useful for debugging codegen tasks or context-aware object factories -- am i missing any existing facilities to do this?

Hey, anybody here have a crazy nice pants command to graph all changed targets ?
