run-tests: add possibility for test-runners to report a "warned" test result A test result is recognized as "warned" when the test runner returns the exit code False. (False is similar to 0, which is reporting a command has run sucessfully.) The only difference in display is that the failure message while running writes "Warning:" instead of "ERROR:". The diff output is the same as when the test fails. Runing "run-tests.py -i" asks to accept the changed result also for tests reported as "warned". When running tests, a "warned" test would look like this: .. --- xxxx\tests\test-something.t +++ xxxx\tests\test-something.t.err @@ -1279,7 +1279,7 @@ $ echo anything $ hg commit -S -m whatever committing subrepository s - committing subrepository s/sbs + committing subrepository s/sbs (glob) warning: something happened committing subrepository t $ echo something Warning: xxxx\tests\test-sOMETHING.t output changed ~.s...s...s.. Reporting a test result as "warned" will be used in following patches. [ original upstream message ]
