Description

Description of the feature request:

I saw "no-local" as an execution requirement here:

https://github.com/bazelbuild/bazel/blob/3be81016f463d7a19cef5f00fee89efdd887c1b6/src/main/java/com/google/devtools/build/lib/actions/ExecutionRequirements.java#L243

But I was told that this is only for the internal Blaze, not Bazel. Can we have support for "no-local" in Bazel as well?

Which category does this issue belong to?

No response

What underlying problem are you trying to solve with this feature?

Similar to "no-remote" or "no-sandbox", sometimes I need to ensure an action to be ALWAYS executed with some level of isolation. For me, this means this particular action can use process-wrapper, linux-sandbox, or RBE. This particular action writes to the source tree, so it can't use the local strategy to avoid it to actually write to the source tree.

Which operating system are you running Bazel on?

Linux

What is the output of bazel info release?

8.3.1

If bazel info release returns development version or (@non-git), tell us how you built Bazel.

No response

What's the output of git remote get-url origin; git rev-parse HEAD ?

Have you found anything relevant by searching the web?

No response

Any other information, logs, or outputs that you want to share?

Research direction
The issue requests adding support for a 'no local' execution requirement, analogous to existing 'no remote'. Start by examining the ExecutionRequirements.java file referenced in the issue (src/main/java/com/google/devtools/build/lib/actions/ExecutionRequirements.java). Look at how 'no remote' is implemented and create a similar mechanism for 'no local'. Then, modify the strategy selection logic to skip local execution when this requirement is set. Check for existing tests and add new ones. The issue comments may provide additional context.
