[jira] Created: (ODE-807) Infinite Loop when locating unresolved
functions in XPath expression
Infinite Loop when locating unresolved functions in XPath expression
--------------------------------------------------------------------
Key: ODE-807
URL: https://issues.apache.org/jira/browse/ODE-807
Project: ODE
Issue Type: Bug
Affects Versions: 2.0-beta2, 2.0-beta1, 1.3.3
Reporter: David Carver
An infinite loop will occur in the extractFunctions method, when the following XPath expression is passed into it:
concat(current-date() + xs:dayTimeDuration(concat("P", $DAYS_TO_NEXT_REMINDER, "D")), "T", "08:30:00.000+08:00")
The loop happes when location the : in "08:30:00"
The " gets located, and the index gets reset to the colonIndex, causing an infinite loop to occur.
I'm working on a patch for this issue now.

[jira] Updated: (ODE-807) Infinite Loop when locating unresolved
functions in XPath expression
Posted by "David Carver (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/ODE-807?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Carver updated ODE-807:
-----------------------------
Attachment: ode1.x-807-v1.txt
Proposed patch to correctly extract all functions that may not have been previously resolved. This uses a RegEx pattern to identify the possible functions and extract them. Test cases have been included to verify that namespace prefixed functions are being extracted since these are the ones that aren't likely to be resolved.
The infinite look would occur because the existing code had problems dealing with timestamps that had a : in them. It assumed that the : was always being used to represent a prefix for either a node of function.
