# This is a transitional wrapper that's only meant for the CI.
|
|
# Developers should directly invoke on or two of:
|
|
# - tests/scripts/mbedtls-all.sh ...
|
|
# - (cd tf-psa-crypto && tests/scripts/all.sh ...)
|
|
#
|
|
# During the transition, it's illegal for a tf-psa-crypto component to have
|
|
# the same name as an mbedtls components; since this wrapper handles both
|
|
# sides at once, component names need to be globally unique. Once the
|
|
# transition period is over, unicity on each side will be enough.
|
|
#
|
|
# For context, here are the steps of the transition:
|
|
# 1. We have an all.sh in tf-psa-crypto but for now we don't invoke it directly
|
|
# on the CI, only through this transitional wrapper in mbedtls. (tf-psa-crypto
|
|
# doesn't have its own CI initially and runs Mbed TLS's instead.)
|
|
# 2. We move all relevant components to tf-psa-crypto so that it gets the level of
|
|
# coverage we want. We need to make sure the new names are unique.
|
|
# 3. We change the CI job on tf-psa-crypto to stop checking out mbedtls and running
|
|
# its all.sh - instead we do the normal thing of checking out tf-psa-crypto and
|
|
# running its all.sh. (In two steps: (a) add the new job, (b) remove the old
|
|
# one.)
|
|
# 4. We remove the transitional wrapper in mbedtls and we're now free to rename
|
|
# tf-psa-crypto components as we want. If we followed a consistent naming
|
|
# pattern, this can be as simple as s/_tf_psa_crypto// in components-*.sh.
|
|
|
|
# This script must be invoked from the project's root.
|
|
|
|
# There are exactly 4 ways this is invoked in the CI:
|
|
# 1. tests/scripts/all.sh --help
|
|
# 2. tests/scripts/all.sh --list-all-components
|
|
# 3. tests/scripts/all.sh --list-components
|
|
# 4. tests/scripts/all.sh --seed 4 --keep-going single_component_name
|
|
# This wrapper does not support other invocations.
