----------------------------------------
Hi Devs, Is this patches are complete? Can I commit them into svn ?
> guththila parser does not handle incomplete messages well, leading to an
> infinite loop or seg fault

> Key: AXIS2C-933
> URL: https://issues.apache.org/jira/browse/AXIS2C-933
> Project: Axis2-C
> Issue Type: Bug
> Components: guththila
> Affects Versions: Current (Nightly)
> Environment: Windows XP, Visual Studio 2005, guththila, libcurl
> Reporter: Bill Mitchell
> Attachments: diff.txt, diff2.txt
>
>
> The code in the guththila parser has a couple of problems when the first
> allocated buffer fills up and it attempts to read more data. First, when
> allocating another buffer it doubled the size of all the buffers allocated to
> this point, but then recorded the new buffer size as only equal to the size
> of all the previous buffers. Second, after fixing the buffer allocation
> issue, I discovered that the read into the buffer tried to read as much as
> all the buffers to date, instead of just the amount remaining in the buffer
> just allocated. There is also a subtle problem in the guththila_next_no_char
> routine if last_start is not set, that it did not assure that all the
> characters since next are moved to the newly allocated buffer.
> While debugging this, because of other issues, I walked through the path of
> an unexpected EOF in the middle of the incoming message, and discovered that
> several while loops in the parser do not stop on EOF, but just keep reading
> and reading and reading...
