---------------------------------
Thanks for filing the bug and the patch. I don't know what I was thinking with
that format string :)
> SPDY plugin will hang after several requests
> --------------------------------------------

> Key: TS-1525
> URL: https://issues.apache.org/jira/browse/TS-1525
> Project: Traffic Server
> Issue Type: Bug
> Components: Plugins
> Reporter: Conan Wang
> Assignee: James Peach
>
> In a spdy session, plugin will hang if reload the page several times in
> browser.
> Debug log:
> {code}
> (spdy.plugin) spdy_vconn_io:297 received 738 bytes
> (spdy.plugin) spdy_vconn_io:297 received 754 bytes
> (spdy.plugin) spdy_vconn_io:297 received 1442 bytes
> (spdy.plugin) spdy_vconn_io:297 received 1458 bytes
> ....repeat on each reload request....
> {code}
> Some debug info, FYI:
> When hanging, at spdy.cc:204 consume_spdy_frame(), nbytes from
> TSIOBufferBlockReadStart will not grow. So (header.datalen <= (nbytes -
> spdy::message_header::size) can not pass test.
> nbytes from TSIOBufferBlockReadStart is the available bytes of current block,
> which I think should get from TSIOBufferReaderAvail(io->input.reader).
> However, after replacing with TSIOBufferReaderAvail, other issues will raise:
> parsing request header will fail or crash when decompressing header.
