was able to make it work, thanks @aloof-angle-91616

awesome!!!

please let us know if we can help you set up anything else!

@eager-pillow-17915 Hi Charles, we would need a lot more information in order to diagnose this problem. To start with, a stack trace, the version of pants, the contents of your pants.ini, the command you were running.

Can anyone point me at how the

--pants-config-files

option is handled? My normal strategy of grepping for the

_

-version of the

-

flag name (

rg pants_config_files

) shows it’s only used for invalidation globs and in a test, which doesn’t sound right…

pants.ini

just a note, there's some really interesting code in

src/python/pants/option/custom_types.py

. i always wondered at the machinery that made list and dict option value merging work (see e.g.

ListValueComponent

in that file).

Could someone tell me what this error means?

Exception caught: (pants.build_graph.address_lookup_error.AddressLookupError) (backtrace omitted)
Exception message: Build graph construction failed: ExecutionError 1 Exception encountered:
  Exception: Failed to begin read transaction: Resource temporarily unavailable

I get that when I run in a container via `docker-compose run <service> ./pants run <target>`; however, if I

docker-compose run <service> bash

and then run the same pants command, everything works out fine...

Specifically it seems to only happen when I have another container running a ./pants command at the same time (the cache and .pants.d directories are shared by both containers; not sure if this is advisable or not).

I assume it's a locking issue, but can't explain why running it in a bash shell works but not directly in the container.

i'm assuming that error message

Exception: Failed to begin read transaction: Resource temporarily unavailable

is something to do with accessing our LMDB store, which is mapped to files in

~/.cache/pants/lmdb_store

. it's not clear to me why this would be different, but i might first try it without sharing the cache directory and seeing if that runs.

It runs when there's only one process accessing it.

right

i'm thinking we might be making some assumption that things are on the same filesystem somewhere in our interactions with the lmdb store. not sure if that would be too hard to fix cc @average-vr-56795

I'm trying to figure out where

lmdb::Environment

is defined (from here https://github.com/pantsbuild/pants/blob/f5ae1533294493d4c6b57db1a8fd4c97c36406e4/src/rust/engine/sharded_lmdb/src/lib.rs#L32). I'm not seeing a

lmdb

directory in

rust/engine/

nor in the

Cargo.toml

. I'm not very Rust savvy 😕

Oof, just found it; turns out Github search is a thing : https://github.com/pantsbuild/lmdb-rs

it's probably a transitive dep, i might recursively search

Cargo.toml

in the repo like:

> find src/rust/engine -type f -name Cargo.toml | parallel -t rg --color=always lmdb

that will also point you to our fork and the revision it's on

please let us know if you have further questions @cuddly-window-48195, i don't have tons of bandwidth right now to investigate but one of us might later today. also rust codebase questions are typically done in #engine

ok, I'm only in the codebase to try and get clues about what is going on with my general issue, sorry for asking about that here. Any help I can get on my general issue is very much appreciated.

But I understand if you're bandwidth constrained. 🙂

this might also be a constraint due to pantsd

I'm looking for some help in configuring pants to run against a webdav cache. I can't find any docs for configuring the pants.ini accordingly; could someone point me in the right direction?

Pants question: I have a 3rdparty set of jars that live as a

jar_library "foo"

. I need to make a tarball (or other archive) of these and make that available to a

scala_library "bar"

at runtime. The archive should be on the classpath somehow, but NOT the individual jars in that comprise "foo". How can i do this? I've tried my usual "create archive" trick of making a

jvm_binary

target that has

foo

as a dependency, then a

jvm_app

wrapping that with

archive = "tar"

, but now i need to make THIS a runtime dependency of a

bar

. In prior cases, i'd get a tarball from this, but it doesn't seem to be happening Ideas? (NB: again, the jars in

foo

can NOT be directly on the runtime classpath of

bar

. This is a hard requirement.)

PSA: I plan to start the rc0 cut in the evening.

i've decided that a good theme for this weekend would be "finishing my open PRs". travelling, so we'll see

What do the pex.resolver.Untranslatable errors mean? I'm getting

Package SourcePackage('...') is not translatable by ChainedTranslator(WheelTranslator, EggTranslator, SourceTranslator)

.

Above that, I'm seeing
