# Directories used by sandboxed non-worker execution may be reused to avoid unnecessary setup costs.
# Save time on Sandbox creation and deletion when many of the same kind of action run during the
# build.
# No longer experimental in Bazel 6: https://github.com/bazelbuild/bazel/commit/c1a95501a5611878e5cc43a3cc531f2b9e47835b

# Do not build runfiles symlink forests for external repositories under
# `.runfiles/wsname/external/repo` (in addition to `.runfiles/repo`). This reduces runfiles &
# sandbox creation times & prevents accidentally depending on this feature which may flip to off by
# default in the future. Note, some rules may fail under this flag, please file issues with the rule
# author.

# Avoid creating a runfiles tree for binaries or tests until it is needed.

# This may break local workflows that `build` a binary target, then run the resulting program
# outside of `bazel run`. In those cases, the script will need to call
# `bazel build --build_runfile_links //my/binary:target` and then execute the resulting program.
