pmproxy: add mutex for client req lists, fix https/tls support, QA
|
|
|
8a537e |
|
|
|
8a537e |
Add a new mutext to struct proxy and use it to protect parallel
|
|
|
8a537e |
multithreaded updates to the proxy->first client list.
|
|
|
8a537e |
|
|
|
8a537e |
Also use the same mutext to protect updates to the pending_writes
|
|
|
8a537e |
client list and avoid the doubly linked list corruption that was
|
|
|
8a537e |
causing parallel https/tls requests to get stuck spinning in
|
|
|
8a537e |
flush_secure_module(), as reported in BZ#1947989.
|
|
|
8a537e |
|
|
|
8a537e |
qa/1457 is extensively updated to test parallel http, https/tls
|
|
|
8a537e |
(and combinations of http and https/tls) RESTAPI calls. Previously
|
|
|
8a537e |
it only tested a single https/tls call.
|
|
|
8a537e |
|
|
|
8a537e |
With these changes, parallel https/tls RESTAPI requests from the
|
|
|
8a537e |
grafana-pcp datasource to pmproxy now work correctly whereas previously
|
|
|
8a537e |
pmproxy would hang/spin.
|
|
|
8a537e |
|
|
|
8a537e |
Resolves: RHBZ#1947989 - pmproxy hangs and consume 100% cpu if the
|
|
|
8a537e |
redis datasource is configured with TLS.
