curl's test fileformat keyword "swsbounce"

[jay]

I'm in the middle of writing a test for #15333 and I need to provide several different responses to the same request that is repeatedly retried to ensure that pieces of responses can be formed back together into one. The swsbounce option I thought would be ideal but from examining server.response data I can see it allows only a single different response.

For example if I have response data in <data> that contains the keyword swsbounce then for the retry request the test script will use the response data in <data1>. However if data1 contains the keyword swsbounce then for the next request the test script loops back to <data> instead of what I would have expected <data2>.

In other words I end up with responses in this order: <data>, <data1>, <data>, <data1>, <data>, <data1>, etc

But this is what I want: <data>, <data1>, <data2>, <data3>, <data4>, etc

here's an example of how swsbounce normally works, taken from a random test:

As far as I can tell, there is never a data2 in these cases. Can I change swsbounce behavior in the script to not reset back to 0 (ie <data>) can anyone forsee problems with this? Or should I add a new keyword? It's unclear who implemented this behavior.

edit: See #16085 for the proposed fix.

I think you can. I hope that does not cause any problems.
