# This file contains the build configurations of Skia that we use for testing on the CI.
# These allow a short-form reference for our supported combinations of build features.
# https://bazel.build/docs/bazelrc#config
#
# For most build configurations, we will want to set the --cc_output_directory_tag [1]
# with a unique identifier per configuration name.
#
# By default, Bazel's "unique target BuildConfiguration" [2] incorporates the compilation_mode,
# the target platform, and some suffixes to avoid Bazel-caused and user-caused conflicts. [3] [4]
# For example, a default output directory might look like "k8-fastbuild-ST-6a54c1377847".
# Inside this output directory is a subfolder for the target (e.g. executable) name.
#
# Note that multiple definitions of a config are allowed - in this event, they are added together.
# This is handy if we need to comment on why certain settings are necessary. Otherwise, escaping
# the trailing newline (and thus having a multi-line definition) is preferred for brevity.
#
# Notably, the flags that we turn on and off via //bazel/common_config_settings do not affect
# the output directory. The output directory is used to store compiled object files (.o files)
# and generated dependency files (e.g. the output of clang --write-dependencies [5]), so having
# these be overwritten unnecessarily will slow down incremental rebuilds when switching between
# building different configurations of the same targets.

# Targets (what to build for)
# =============================================================================
# --platforms refers to the target for which we are compiling. By setting the target to be a
# platform which has our own custom constraint_setting and constraint_value
# (skia_hermetic_toolchain=use_hermetic_toolchain), this causes Bazel to resolve the toolchain
# to be our hermetic one because our hermetic toolchains have that same constraint set in their
# target_compatible_with list.
