When running in cluster mode, passing references does not work, e.g.,:

auto r3 = Ray::Task(Return1).Remote();
auto r4 = Ray::Task(Plus1, r3).Remote(); // passing r3 as reference argument

• I have verified my script runs in a clean environment and reproduces the issue.

Summary

Today in the R package, there are a lot of internal function calls which use only positional arguments. Change them to use keyword arguments for extra safety.

I've added this issue to provide a small, focused contribution opportunity for Hacktoberfest 2020 participants. If you are an experienced open source contributor, please leave this

See: numba/numba#6368 (comment)

The values tested will be random for each invocation of the tests, because there is no RNG seeding. The RNG should be seeded for each test, so that values are stable.

See optuna/optuna#1913.

Some type hints are not complying to the latest mypy == 0.790 and should be addressed.

Expected behavior

Some progress or update information during the creation of the SIF file.

Actual behavior

During "Creating SIF file..." step, the console does not produce any visible output for the user - but does create the resulting file eventually.

Steps to reproduce behavior

I was executing a few “larger” builds through the bui

Explain what you would like to see improved

We had CI builds stuck in downloading dependencies, e.g. VecCore. That should timeout.

Optional: share how it could be improved

Add the TIMEOUT parameter to all ExternalProject calls downloading sources.

Feature request

The asynchronous functionality of parallel-ssh is very much appreciated for management tasks. Thank you for this!

For the feature request:

It seems that the open_session() can keep worker allocated for much longer than expected in failure cases. Would it be reasonable to stretch the timeout option of wait_socket() to open_session() ?
