[jira] [Created] (TS-1100) Coredump at startup when there's a
duplicate remap rule
Coredump at startup when there's a duplicate remap rule
-------------------------------------------------------
Key: TS-1100
URL: https://issues.apache.org/jira/browse/TS-1100
Project: Traffic Server
Issue Type: Bug
Components: Core
Affects Versions: 3.1.1
Environment: Bog standard linux/x86; own build.
Reporter: Nick Kew
Priority: Minor
A minor accident with cut&paste in vi leads to TS coredumping at startup.
I had duplicated a line in remap.config:
map http://myhost:8080/ http://target/
(....)
map http://myhost:8080/ http://target/
The second instance is line 125 in remap.config, and the dump shows:
FATAL: [ReverseProxy] Unable to add mapping rule to lookup table at line 125
bin/traffic_server - STACK TRACE:

Leif Hedstrom commented on TS-1100:
-----------------------------------
This is sort of by design, it refuses to start up with a bad remap.config. The reason you get a segfault is because our destructors are running on uninitialized objects :-/.

Nick Kew commented on TS-1100:
------------------------------
To exit at startup on such an error - fine (though a clear error message would be helpful - starting up through the trafficserver script leaves only cryptic failure).
But a coredump? What kind of "by design" is that?

[jira] [Resolved] (TS-1100) Coredump at startup when there's a
duplicate remap rule
Posted by "Nick Kew (Resolved) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/TS-1100?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Nick Kew resolved TS-1100.
--------------------------
Resolution: Duplicate
Turns out this is indeed TS-948, and I was using the wrong symlink that caused me to think I saw it in 3.1.1.
