scripts/resulttool/regression: add metadata filtering for oeselftest
When generating regression reports, many false positive can be observed since some tests results are compared while the corresponding tests sets are not the same, as it can be seen for example for oeselftest tests (oeselftest is run multiple time but with different parameters, resulting in different tests sets) Add a filtering mechanism in resulttool regression module to enable a better matching between tests. The METADATA_MATCH_TABLE defines that when the TEST_TYPE is "oeselftest", then resulttool should filter pairs based on OESELFTEST_METADATA appended to test configuration. If metadata is absent from test results, in order to keep compatibility with older results, add a "guessing" mechanism to generate the missing OESELFTEST_METADATA. The guessed data is tightly coupled to the autobuilder configuration, where all oe-selftest executions are described Signed-off-by: Alexis Lothoré <alexis.lothore@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
