TS-2279: Update range for proxy.config.exec_thread.affinity
> proxy.config.exec_thread.affinity's values
> ------------------------------------------
>
> Key: TS-2279
> URL: https://issues.apache.org/jira/browse/TS-2279
> Project: Traffic Server
> Issue Type: Bug
> Components: Configuration
> Reporter: Igor Galić
> Assignee: Phil Sorber
> Fix For: 5.1.0
>
>
> The setting of {{proxy.config.exec_thread.affinity}} only has an affect when
> traffic server was compiled with {{\-\-enable-hwloc}}. It has *no* affect at
> all, not even a warning about its being ineffectual when setting that value
> while trafficserver is *not* configured with {{--enable-hwloc}}.
> Further, mgmt/RecordsConfig.cc defines a range of {{[0-1]}}:
> {code}
> {RECT_CONFIG, "proxy.config.exec_thread.affinity", RECD_INT, "0",
> RECU_RESTART_TS, RR_NULL, RECC_INT, "[0-1]", RECA_READ_ONLY}
> {code}
> but the code uses a range of [0-3]:
> {code}
> #if TS_USE_HWLOC
> if (affinity != 0) {
> int logical_ratio;
> switch(affinity) {
> case 3: // assign threads to logical cores
> logical_ratio = 1;
> break;
> case 2: // assign threads to real cores
> logical_ratio = pu / cu;
> break;
> case 1: // assign threads to sockets
> default:
> logical_ratio = pu / socket;
> }
> {code}
> And finally, 1 is the default value, rather than issuing a warning about an
> incorrect value.
