# BUILD ARTIFACT CACHING
#
# We need to ensure that changes to a dependency's configure or CMake flags
# below cause the corresponding dependency to be rebuilt. It would be correct to
# have the dependencies list this file itself as a prerequisite, but *all*
# dependencies would be rebuilt, likely unnecessarily, whenever this file
# changed. Instead, we give each dependency its own marker file, DEP-rebuild, as
# a prerequisite.
#
# It's not important *what* goes in the marker file, so long as its contents
# change in the same commit as the configure flags. This causes Git to touch the
# marker file when switching between revisions that span the change. For
# simplicity, just sequentially bump the version number within.
#
# NB: the recipes below nuke *all* build artifacts when a dependency's configure
# flags change. In theory, we could rely on the dependency's build system to
# only rebuild the affected objects, but in practice dependencies on configure
# flags are not tracked correctly, and these stale artifacts can cause
# particularly hard-to-debug errors.
#

# Most of our C and C++ dependencies use Makefiles that are generated by CMake,
# which are rather slow, taking upwards of 500ms to determine that nothing has
# changed. The no-op case is the common case, as C and C++ code is modified
# rarely relative to Go code.
#
# So, for speed, we want to avoid invoking our C and C++ dependencies' build
# systems when nothing has changed. We apply a very coarse heuristic that works
# well in practice: if every file in a given library's source tree is older than
# the compiled library, then the compiled library must be up-to-date.
#
# Normally, you'd accomplish this in Make itself by declaring a prerequisite for
# every file in the library's source tree. For example, you'd have a rule like
# this for protoc:
#
#     $(PROTOC): $(PROTOC_DIR)/Makefile $(shell find c-deps/protobuf)
#       $(MAKE) -C $(PROTOC_DIR) protoc
#
# Note the prerequisite that shells out to the 'find' command. Unfortunately,
# this winds up being as slow as unconditionally invoking the child build
# system! The cost of repeated find invocations, one per command, adds up, plus
# Make needs to stat all of the resulting files, and it seems to do so
# sequentially.
#
# Instead, we unconditionally run the recipe for each C and C++ dependency, via
# .ALWAYS_REBUILD, but condition the execution of the dependency's build system
# on the output of uptodate, a Go binary of our own design. uptodate walks and
# stats the directory tree in parallel, and can make the up-to-date
# determination in under 20ms.
