Andy Seaborne commented on THRIFT-5022:
---------------------------------------
[~q.xu] Thank you for the quick response.
I've just done [PR #1942|https://github.com/apache/thrift/pull/1942] that turns
the "&&" into an "||" on whether either inputStream_ or outputStream_ is
non-null.
close() already clears inputStream_ or outputStream_.
So this is equivalent to a flag for "isOpen" without the additional field.
Your suggestion would be to catch Throwable in close()? I can add that is that
helps.
> TIOStreamTransport.isOpen is false for InputStream or Outpstream only use.

> This follows from THRIFT-2530.
> {{TIOStreamTransaport.isOpen}} changed to be
>
> {noformat}
> public boolean isOpen() {
> return inputStream_ != null && outputStream_ != null;
> }
> {noformat}
> but constructors {{TIOStreamTransaport(InputStream)}} and
> {{TIOStreamTransaport(OutputStream)}} leave one of {{inputStream_}} or
> {{outputStream_}} null.
> This makes isOpen false immediately, no close() called. open() does not
> change the state of object.
> Example:
> {noformat}
> TIOStreamTransport x1 = new TIOStreamTransport(new ByteArrayInputStream(new
> byte[1]));
> System.out.println(x1.isOpen());
> TIOStreamTransport x2 = new TIOStreamTransport(new ByteArrayOutputStream());
> System.out.println(x2.isOpen());
> {noformat}
> is prints false both times.
>
> It should be:
> {noformat}
> public boolean isOpen() {
> return inputStream_ != null || outputStream_ != null;
> }
> {noformat}
> or an explicit flag for the open/close state but {{inputStream_ != null ||
> outputStream_ != null;}} is enough given the current close implementation.
