      Description

      Need to extend the Command base class to allow all command to easily subclass from a code set of code that correctly handles globs and exit codes.

          Add many methods to Command class to facilitate easy overriding for custom behavior. Add PathData class to encapsulate a path, fs, and filestatus to avoid passing so many args and/or multiple lookups during execution. Modify Count cmd to conform since it was the simplest one.

          (Note: changes in FsShell are temporary, since all the if/then/elses for commands will soon become a generic call to a command object.)

          Tanping Wang added a comment -

          I looked at the patch and think it looks good to me with only a few comments,

          1) In PathData.java, class member exists which is a Boolean variable, its value is determined by checking if FileStatus is null. Since FileStatus is another class member, by checking whether FileStatus is null, we can already know if the Path exists. So I think we can eliminate this "exist" member variable?

          2) In Command.java#displayError(Exception e)

              if (errorMessage == null) {
                errorMessage = e.toString();
              }
          

          StringUtils.stringifyException() is a common utility function which makes a string representation of the exception. I think using this is better than just toString()
          Also, it would be a good idea to log a debug message using LOG.debug to print out the full exception stack trace, so that debugging is easier.

          3) In Command.java#run()

             * @throws IllegalArgumentException if the option parsing fails
          

          would it be a good idea to link the function, so it is more clear? i.e.

          • @throws IllegalArgumentException if {@link processOptions(args)}

            fails

          I am confused about the other throws comment

             * @throws non-IOExceptions such rpc failures
          

          4) In Command.java#run(String, cmd, LinkedList<String> args)
          the exit code of error was -1 in the original code, it is now changed to 1. Although it does not matter as long as it is non-zero value, why not keep it the same?

          5) You are making the methods in PathData.java public, just making it package default by removing the "public" should be sufficient enough in our case?

          1) I feel that "if (item.exists)" is more intuitive to a reader of external code than "if (item.stat != null)". I will change it if you feel strongly.

          2) Great idea.

          3) I went back and added javadocs links to all my new methods. Phew.

          4) I'm trying to more closely follow unix conventions. Also, -1 for invalid usage versus 1 for execution failure, allows external scripts to differentiate the mode of failure.

          5) There are other external commands that subclass Command and will need access to this class if updated, so I don't think I can reduce the visibility.

          Fixed javadoc link warning from mis-capitalized method name.

          The javac warnings are due to FsCommand.java stubbing out unnecessary abstract methods which happen to be deprecated. The deprecations are generating the warnings.

          Added annotations for audience and stability.

          I am unable to remove the abstract methods that I marked as deprecated (and then stubbed in FsCommand) because other tools are depending on this class. I'm relatively certain the new apis are firm, but I'd now like to hold off on adding the deprecations until FsShell is completed.
