Phil Sorber commented on TS-2279: --------------------------------- [~zwoop], I think we can add a warning easily, but this code has changed I think since this ticket was opened. We should update the docs. > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
