[jira] [Created] (TS-1525) SPDY plugin will hang after several
requests
Conan Wang created TS-1525:
------------------------------
Summary: 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
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.

As for malformed status line and incorrect warning at error.log : [spdy] client is version 2, but we implement version 3, following change is OK for me.
