# Note: The output of the --version command differs based on the presence of a RELEASE_VERSION file during bazel workspace status generation.
# If the file is present, the --version command output will include the content of the file as a prefix to the text after the first '/'.
# For example:
# bazel-bin/envoy  version: 2f7ac770075de46ce960f4da95b40bd49834dcb1/20240104-1.26.3-65-g2f7ac77/Modified/DEBUG/BoringSSL
# where 20240104 is taken from the RELEASE_VERSION file.
# If RELEASE_VERSION was not present, the --version command output would be:
# bazel-bin/envoy  version: 2f7ac770075de46ce960f4da95b40bd49834dcb1/1.26.3-65-g2f7ac77/Modified/DEBUG/BoringSSL
# This prefix is optionally captured by the second regex capture group below.

# Example expected COMMIT: 2f7ac770075de46ce960f4da95b40bd49834dcb1
