    Description

      ts_sal includes support for two data types (at least) that we aren't using and don't appear to be necessary:

      • char: this is an alias for "string" and is very confusing to me because it sounds like a single 8-bit int (the C definition) instead of a string. It is not used (except in Test).
      • octet: it's not being used (except in Test). Do we need it?

      I think all the remaining types I know about are used and are fairly self-explanatory.

      Would it be practical to remove support for either or both of these? Clearly it is not a high priority and it will be slightly disruptive because it will require minor changes to Test XML and unit tests in ts_sal and ts_salobj (which I am happy to do).

      Also: does ts_sal support "unsigned long long" and if not, would that be easy to add? It would be useful for long bitmasks. It's not a big deal because "long long" works, but unsigned is a more natural choice for bitmasks.

            char and octet have been removed as vaild types in the XML.
            Note that "octet" is the IDL equivalent of "byte or unsigned 8-bit"
            so it will still appear in the IDL.

            The char and octet data-types have been removed.  XML will need to be updated accordingly or tests will break.

            I think it will suffice to release ts_xml 9.2 before we release this change in ts_sal.

            The only use of char and octet that I know of in ts_xml 9.1 is in the Test SAL component. I removed those fields July 9, in DM-31017.
