[jira] [Commented] (TS-4355) Assert in HttpTunnel fails when access
with HTTP/2
[ https://issues.apache.org/jira/browse/TS-4355?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15244599#comment-15244599 ]
Masakazu Kitajo commented on TS-4355:
-------------------------------------
The assertion in HttpTunnel.cc
{code}
if ((c = get_consumer((VIO *)data)) != 0) {
ink_assert(c->write_vio == (VIO *)data);
{code}
TS-3612 changes the behavior of {{HttpTunnel::get_consumer(VIO *vio)}}. So assertion fails if the latter condition, {{consumers\[i\].vc == vio->vc_server}}, is true.
{code}
inline HttpTunnelConsumer *
HttpTunnel::get_consumer(VIO *vio)
{
- for (int i = 0; i < MAX_CONSUMERS; i++) {
- if (consumers[i].write_vio == vio) {
- return consumers + i;
+ if (vio) {
+ for (int i = 0; i < MAX_CONSUMERS; i++) {
+ if (consumers[i].write_vio == vio || consumers[i].vc == vio->vc_server) {
+ return consumers + i;
+ }
}
}
return NULL;
{code}
I'm unsure about this, but it works if I remove the assert.
