ASF GitHub Bot commented on TS-3650: ------------------------------------ Github user SolidWallOfCode commented on the pull request: https://github.com/apache/trafficserver/pull/206#issuecomment-107638211 The chat concensus seemed to be to change this to NULL, DEFAULT, EXPLICIT, ENV. I'll change "SRC" to "SOURCE" as well - I was tempted to have "RECS" which would be more consistent with the other REC values but that seemed even worse scanning. > Configuration variables should track their source > ------------------------------------------------- > > Key: TS-3650 > URL: https://issues.apache.org/jira/browse/TS-3650 > Project: Traffic Server > Issue Type: Improvement > Components: Configuration > Reporter: Alan M. Carroll > Assignee: Alan M. Carroll > > A configuration variable can get its value from a variety of sources. It > would be useful to be able to programmatically determine that source. At a > minimum the ability to determine if a variable was set explicitly in a > configuration file vs. using a built in default value would be very useful. > In addition this information should be made available to the administrator > via {{traffic_ctl}} to aid in debugging. > The proposed values are > * {{DEFAULT}} - built in default, hard wired. > * {{FILE}} - read from a configuration file. > * {{API}} - set via an API of some sort ({{traffic_line}} etc.) > * {{CLUSTER}} - set via cluster configuration > * {{ENV}} - set from an environment variable > In addition the value {{INVALID}} will be defined to use for the internal > API, primarily as a value to return if the requested variable doesn't exist > (in which case none of the previous values are reasonable). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
