# Commands for building the container if you are changing the requirements      #
#################################################################################

## Builds the container locally
build:
	docker build --build-arg CPU_OR_GPU=${CPU_OR_GPU} -t ${LOCAL_IMAGE}:${LOCAL_TAG} runtime

## Ensures that your locally built container can import all the Python packages successfully when it runs
test-container: _check_image _echo_image _submission_write_perms
	docker run \
		${GPU_ARGS} \
		${TTY_ARGS} \
		--mount type=bind,source="$(shell pwd)"/runtime/tests,target=/tests,readonly \
		--pid host \
		--entrypoint /bin/bash \
		${SUBMISSION_IMAGE_ID} \
		-c "conda run --no-capture-output -n condaenv python -m pytest tests"

## Open an interactive bash shell within the running container (with network access)
interact-container: _check_image _echo_image _submission_write_perms
	docker run \
		${GPU_ARGS} \
		--mount type=bind,source="$(shell pwd)"/data,target=/code_execution/data,readonly \
		--mount type=bind,source="$(shell pwd)"/submission,target=/code_execution/submission \
		--shm-size 8g \
		--pid host \
		-it \
		--entrypoint /bin/bash \
		${SUBMISSION_IMAGE_ID}

## Pulls the official container from Azure Container Registry
pull:
	docker pull ${OFFICIAL_IMAGE}:${TAG}

## Creates a submission/submission.zip file from the source code in examples_src
pack-example:
# Don't overwrite so no work is lost accidentally
ifneq (,$(wildcard ./submission/submission.zip))
	$(error You already have a submission/submission.zip file. Rename or remove that file (e.g., rm submission/submission.zip).)
endif
	mkdir -p submission/
	cd examples_src/${EXAMPLE}; zip -r ../../submission/submission.zip ./*

## Creates a submission/submission.zip file from the source code in submission_src
pack-submission:
# Don't overwrite so no work is lost accidentally
ifneq (,$(wildcard ./submission/submission.zip))
	$(error You already have a submission/submission.zip file. Rename or remove that file (e.g., rm submission/submission.zip).)
endif
	mkdir -p submission/
	cd submission_src; zip -r ../submission/submission.zip ./*

## Runs container using code from `submission/submission.zip` and data from `data/`
test-submission: _check_image _echo_image _submission_write_perms
# if submission file does not exist
ifeq (,$(wildcard ./submission/submission.zip))
	$(error To test your submission, you must first put a "submission.zip" file in the "submission" folder. \
	  If you want to use the benchmark, you can run `make pack-example <benchmark name>` first)
endif
	docker run \
		${TTY_ARGS} \
		${GPU_ARGS} \
		${NETWORK_ARGS} \
		--env "LOGURU_LEVEL=INFO" \
		--mount type=bind,source="$(shell pwd)"/data,target=/code_execution/data,readonly \
		--mount type=bind,source="$(shell pwd)"/submission,target=/code_execution/submission \
		--shm-size 8g \
		--pid host \
		--name ${CONTAINER_NAME} \
		--rm \
		${SUBMISSION_IMAGE_ID}

## Delete temporary Python cache and bytecode files
clean:
	find . -type f -name "*.py[co]" -delete
	find . -type d -name "__pycache__" -delete
