Commit 22c5402b0f0b9957e307a7ad032ab118b2399c49 in kudu's branch
refs/heads/master from Attila Bukor

KUDU-3079 Add MiniPostgres
Apache Ranger needs a database to store privileges and supported
databases currently are MySQL, PostgreSQL, Oracle and Amazon RDS[1].
I ruled out Amazon RDS on the basis that it's cloud-based so we couldn't
depend on it in integration tests in a self-contained way.
This is only a build-time dependency (test-time really) and only for an
optional feature, so licensing shouldn't be too much of a concern for
any of them, but PostgreSQL License can even be included in ASF
software[2]. It's also easy to build and configure and it doesn't
otherwise matter which database is used under Ranger, so I went with
Postgres.
This patch adds the latest (at the time of the start of this work)
PostgreSQL and PostgreSQL JDBC driver JARs to thirdparty and adds a
MiniPostgres interface that tests can use to start Postgres, add users
and create databases.
The patch also adds two utility methods that MiniPostgres uses:
- Subprocess::WaitAndCheckExitCode() is the same as Wait(), but it only
returns OK if the exit code is 0. If the subprocess was killed, stopped
or exited with a non-zero exit code, it fails.
- GetRandomPort() in net_util.h that returns a random unused port.
I also removed the BaseName(argv[0]) call in Subprocess as that doesn't
seem to be the correct behavior according to exec(3) man page as Adar
pointed out.
