Amichai Rothman created CASSANDRA-5340:
------------------------------------------
Summary: use getopts instead of getopt in shell script
Key: CASSANDRA-5340
URL: https://issues.apache.org/jira/browse/CASSANDRA-5340
Project: Cassandra
Issue Type: Bug
Affects Versions: 1.2.2
Environment: Windows XP msysgit GNU bash 3.1.0
Reporter: Amichai Rothman
Priority: Minor
I don't know what the officially supported platforms are or what versions of sh
they support... however I do know that the cassandra startup script fails on at
least one platform (Windows XP/msysgit) since it uses the external utility
getopt which is not available there. Using the shell built-in getopts command
instead, or parsing the command line manually, would fix the problem.
I'm no shell expert, but a little searching came up with the fact that the
getopt utility is not required by POSIX (which a script comment claims needs to
be adhered to) whereas getopts is standard and more portable. Some claim getopt
is better when long option names need to be supported, however cassandra
doesn't use those anyway.
Unless someone knows of a supported platform that doesn't support getopts, the
script should be changed to use it instead of getopt. If such a platform
exists, perhaps using neither (manually parsing args) should be considered -
it's not too much work, and there are plenty of existing templates for doing
this to build on, and that would provide the best portability across platforms.
