Dimitry Andric updated TS-3645:
-------------------------------
Environment: RHEL 6.x, CentOS 6.x (on x86_64)
Affects Version/s: 6.0.0
5.3.0
> After TS-3033, some traffic_line commands result in "requested command failed"
> ------------------------------------------------------------------------------
>
> Key: TS-3645
> URL: https://issues.apache.org/jira/browse/TS-3645
> Project: Traffic Server
> Issue Type: Bug
> Components: Management API
> Affects Versions: 5.3.0, 6.0.0
> Environment: RHEL 6.x, CentOS 6.x (on x86_64)
> Reporter: Dimitry Andric

> I recently upgraded from trafficserver 4.x to 5.3.0, and one thing that I
> noticed was that certain traffic_line commands started printing "requested
> command failed". For example:
> {noformat}
> # trafficserver start
> Starting Apache Traffic Server: [ OK ]
> # traffic_line --status
> Proxy -- on
> # traffic_line --shutdown
> error: the requested command failed: [11] Invalid parameters passed into
> function call.
> # traffic_line --startup
> error: the requested command failed: [11] Invalid parameters passed into
> function call.
> {noformat}
> Interestingly, even if the --shutdown command gives such an error message,
> the diags.log file still shows that the server has shut down:
> {noformat}
> [May 28 22:03:03.539] Server {0x2abe4251d700} NOTE:
> [ProcessManager::processEventQueue] Shutdown msg received, exiting
> {noformat}
> and the --status command also finds the same:
> {noformat}
> # traffic_line --status
> Proxy -- off
> {noformat}
> Similar for the --startup command: though it gives the same error message,
> the command seems to have actually worked.
> I did some bisecting to find where this was introduced, and ended up at
> [commit
> 355c165|https://git-wip-us.apache.org/repos/asf?p=trafficserver.git;a=commit;h=355c165]
> (TS-3033: fix PROXY_STATE_GET). Before this particular commit, both
> {{traffic_line --shutdown}} and {{traffic_line --startup}} work without
> printing any error; after the commit, they both start printing "requested
> command failed".
> If I look at all the work done in TS-3033, and the particular change in
> [commit
> 355c165|https://git-wip-us.apache.org/repos/asf?p=trafficserver.git;a=commit;h=355c165],
> I would guess that some parts of the code are disagreeing about the number
> of parameters for the PROXY_STATE_GET message.
> Alternatively, there may be some sort of issue in the management API and/or
> marshalling code, where a PROXY_STATE_GET message with two parameters gets
> "cut off" in some way, possibly because the server is just shutting down at
> that point?
