annotate proxy_next_upstream.t @ 289:cbd4f6eca676

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Tests: check if started process is alive while starting nginx. This allows faster test execution in case of startup failures, e.g. due to configuration errors. Note that just adding waitpid() to waitforfile() causes hang on win32 in wait(). To fix this, wait() calls were changed to waitpid() with pid specified.
