Gancho Tenev created TS-4935: -------------------------------- Summary: Adding same element twice in a row damages DLL's structure silently Key: TS-4935 URL: https://issues.apache.org/jira/browse/TS-4935 Project: Traffic Server Issue Type: Bug Components: Core Reporter: Gancho Tenev
If the DLL list (lib/ts/List.h) is used improperly its internal structure gets damaged silently without any indication to the caller (no assert or return code). If the the same element is added twice in a row the element's “next” would start pointing to the element itself and all the existing list content would be lost. All further additions will be OK but the next list traversal will be infinite. Also noticed that when a new element is added to the list the element’s “prev” is not initialized (not a problem in the most common case but should to be fixed). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
