[PATCH] tracing/selftests: Update synthetic event selftest to use common_stacktrace

by Steven Rostedt

From: "Steven Rostedt (Google)" <rostedt(a)goodmis.org> With the rename of the stacktrace field to common_stacktrace, update the selftests to reflect this change. Copy the current selftest to test the backward compatibility "stacktrace" keyword. Also the "requires" of that test was incorrect, so it would never actually ran before. That is fixed now.

[PATCH v2 00/11] A minor flurry of selftest/mm fixes

by John Hubbard

Hi, This is v2 of a series that fixes up build errors and warnings for at least the 64-bit builds on x86 with clang. There are lots of changes since v1 [1], thanks to reviews from Peter Xu, David Hildenbrand, and Muhammad Usama Anjum. These include: * Using "make headers", and documenting that prerequisite as well. * Better ways to avoid clang's Wformat-security warnings * Added Cc's, ack-by's, reviewed-by's. * Updated commit log messages. The series also includes an optional "improvement" of moving some uffd code into uffd-common.[ch], which is proving to be somewhat controversial, and so if that doesn't get resolved, then patches 9 and 10 may just get dropped. They are not required in order to get a clean build, now that "make headers" is happening.

[PATCH] selftests: allow runners to override the timeout

by Luis Chamberlain

The default timeout for selftests tests is 45 seconds. Although we already have 13 settings for tests of about 96 sefltests which use a timeout greater than this, we want to try to avoid encouraging more tests to forcing a higher test timeout as selftests strives to run all tests quickly. Selftests also uses the timeout as a non-fatal error. Only tests runners which have control over a system would know if to treat a timeout as fatal or not. To help with all this: o Enhance documentation to avoid future increases of insane timeouts o Add the option to allow overriding the default timeout with test runners with a command line option Suggested-by: Shuah Khan <skhan(a)linuxfoundation.org> Signed-off-by: Luis Chamberlain <mcgrof(a)kernel.org> --- Documentation/dev-tools/kselftest.rst | 22 +++++++++++++++++++++ tools/testing/selftests/kselftest/runner.sh | 11 ++++++++++- tools/testing/selftests/run_kselftest.sh | 5 +++++ 3 files changed, 37 insertions(+), 1 deletion(-) diff --git a/Documentation/dev-tools/kselftest.rst b/Documentation/dev-tools/kselftest.rst index 12b575b76b20..dd214af7b7ff 100644 --- a/Documentation/dev-tools/kselftest.rst +++ b/Documentation/dev-tools/kselftest.rst @@ -168,6 +168,28 @@ the `-t` option for specific single tests.

Tests can override the default timeout by adding +a settings file in their directory and set a timeout variable there to the +configured a desired upper timeout for the test. Only a few tests override +the timeout with a value higher than 45 seconds, selftests strives to keep +it that way. Timeouts in selftests are not considered fatal because the +system under which a test runs may change and this can also modify the +expected time it takes to run a test. If you have control over the systems +which will run the tests you can configure a test runner on those systems to +use a greater or lower timeout on the command line as with the `-o` or +the `--override-timeout` argument. For example to use 165 seconds instead +one would use: + + $ ./run_kselftest.sh --override-timeout 165 + +You can look at the TAP output to see if you ran into the timeout. Test +runners which know a test must run under a specific time can then optionally +treat these timeouts then as fatal. + Packaging selftests =================== diff --git a/tools/testing/selftests/kselftest/runner.sh b/tools/testing/selftests/kselftest/runner.sh index 294619ade49f..1c952d1401d4 100644 --- a/tools/testing/selftests/kselftest/runner.sh +++ b/tools/testing/selftests/kselftest/runner.sh @@ -8,7 +8,8 @@ export logfile=/dev/stdout export per_test_logging= # Defaults for "settings" file fields: -# "timeout" how many seconds to let each test run before failing. +# "timeout" how many seconds to let each test run before running +# over our soft timeout limit. export kselftest_default_timeout=45 # There isn't a shell-agnostic way to find the path of a sourced file, @@ -90,6 +91,14 @@ run_one() done < "$settings" fi + # Command line timeout overrides the settings file + if [ -n "$kselftest_override_timeout" ]; then + kselftest_timeout="$kselftest_override_timeout" + echo "# overriding timeout to $kselftest_timeout" >> "$logfile" + else + echo "# timeout set to $kselftest_timeout" >> "$logfile" + fi + TEST_HDR_MSG="selftests: $DIR: $BASENAME_TEST" echo "# $TEST_HDR_MSG" if [ ! -e "$TEST" ]; then diff --git a/tools/testing/selftests/run_kselftest.sh b/tools/testing/selftests/run_kselftest.sh index 97165a83df63..9a981b36bd7f 100755 --- a/tools/testing/selftests/run_kselftest.sh +++ b/tools/testing/selftests/run_kselftest.sh @@ -26,6 +26,7 @@ Usage: $0 [OPTIONS] -l | --list List the available collection:test entries -d | --dry-run Don't actually run any tests -h | --help Show this usage info + -o | --override-timeout Number of seconds after which we timeout EOF exit $1 } @@ -33,6 +34,7 @@ EOF COLLECTIONS="" TESTS="" dryrun="" +kselftest_override_timeout="" while true; do case "$1" in -s | --summary) @@ -51,6 +53,9 @@ while true; do -d | --dry-run) dryrun="echo" shift ;; + -o | --override-timeout) + kselftest_override_timeout="$2" + shift 2 ;; -h | --help) usage 0 ;; "") -- 2.39.2
