Subject: [dts] [PATCH v2] ci/initial: Added script to get the tests for a patchset
Date: Wed, 13 Oct 2021 10:19:53 -0400
Message-ID: <20211013141953.28687-1-ohilyard@iol.unh.edu> (raw)
In-Reply-To: <CAHx6DYDbj7pJ_9pdSm9RUi4OU3aA_7f13nuR7_9vNZP8NuJxGQ@mail.gmail.com>

From: Owen Hilyard <ohilyard@iol.unh.edu>

Added a script to ci to allow getting the changed tests for a patchset
to DTS.

Instructions for use are in the module doc comment of the script.

Added a dockerfile that should be updated over time to allow it to run
all DTS CI scripts.

Signed-off-by: Owen Hilyard <ohilyard@iol.unh.edu>

+This script should be run after a patchset has been applied to DTS.
+It will iterate through the import tree in python, looking for any
+test that could possibly have had behavior change due to the patchset.
+It will then output all of those tests to standard out in a line-delimited
+list.
+
+The script will also issue warning to standard error if any of the
+"protected paths" are changed. The warning will be in the format:
+"WARNING: {file_name} is protected"
+
+The script will also issue a warning if a config file is changed. This
+warning is also sent to standard error and takes the form of:
+"WARNING: {file_name} is a config file and was changed"
+
+This script can either be run natively or with the provided dockerfile.
