# This .bazelrc file contains all of the flags required for the toolchain,
# Remote Build Execution, and the Bazel Build Results UI. Specific flags in
# your Bazel command allow you to use only the remote build, to use only the
# results UI, or to use them both together.

# Remote Build Execution requires a strong hash function, such as SHA256.
startup --host_jvm_args=-Dbazel.DigestFunction=SHA256

# Depending on how many machines are in the remote execution instance, setting
# this higher can make builds faster by allowing more jobs to run in parallel.
# Setting it too high can result in jobs that timeout, however, while waiting
# for a remote machine to execute them.
build:remote --jobs=50

# Set several flags related to specifying the toolchain and java properties.
# These flags are duplicated rather than imported from (for example)
# %workspace%/configs/debian8_clang/0.3.0/toolchain.bazelrc to make this
# bazelrc a standalone file that can be copied more easily.
