| # a bug that causes different runtest processes to enumerate the tests |
| # differently, then things will break and some tests will be skipped, while |
| # others will be ran several times. |
| # So, just before a runtest processes runs a specific test it asks |
| # "runtest_file_p" routine whether a particular test is part of |
| # the requested testsuite. We override this function so that it |
| # returns "yes" to the first-arrived runtest process, and "no" to all |
| # subsequent runtest processes -- this is implemented by creating a marker |
| # file, which persist till the end of the test run. We optimize this |
| # a bit by batching 10 tests and using a single marker file for the batch. |
| # |
| # Note that the runtest processes all race each other to get to the next |
| # test batch. This means that batch allocation between testsuite runs |
| # is very likely to change. |
| # |
| # To confirm or deny suspicion that tests are skipped or executed |
| # multiple times due to runtest processes enumerating tests differently ... |
| # 1. Uncomment the three below "verbose -log gcc_parallel_test_run_p ..." |
| # debug print-outs. |
| # 2. Run the testsuite with "-v" added to RUNTESTFLAGS |
| # 3. Extract debug print-outs with something like: |
| # for i in $(find -name "*.log.sep"); do |
| # grep gcc_parallel_test_run_p $i \ |
| # | sed -e "s/\([^ ]*\) \([^ ]*\) \([^ ]*\) \([^ ]*\)/\3 \2/" \ |
| # | sed -e "s#\(/testsuite/[a-z+]*\)[0-9]*/#\1N/#" > $i.order |
| # done |
| # 4. Compare debug print-outs produced by individual runtest processes: |
| # find -name "*.log.sep.order" | xargs md5sum | sort |
| # 5. Check that MD5 hashes of all .order files of the same testsuite match |
| # and investigate if they don't. |
