Oliver Heger commented on CONFIGURATION-281: -------------------------------------------- I did some testing and could reproduce the problem with mock objects. 1) fixed the problem, assuming that the involved Context objects have a meaningful implementation of equals() and hashCode(). Why would 2) be necessary in addition to 1)? > JNDIConfiguration::recursiveGetKeys goes out of stack > ----------------------------------------------------- > > Key: CONFIGURATION-281 > URL: https://issues.apache.org/jira/browse/CONFIGURATION-281 > Project: Commons Configuration > Issue Type: Bug > Affects Versions: 1.2 > Environment: Websphere 5.1 > Reporter: Michiel Kalkman > Fix For: 1.5 > > > There can be cycles in contexts. Websphere 5.1 certainly does have them. > When getKeys() is called on a JNDIConfiguration, eventually > recursiveGetKeys() is called, which calls itself for every subcontext. This > will never stop if there is a cycle. > I would like to suggest the following changes to recursiveGetKeys() to fix > this: > 1) check for each subcontext if it has been processed before. If so, don't > process it. An additional stack argument to recursiveGetKeys() should do the > trick here. > 2) a maxDepth attribute, like <jndi maxDepth="4"/>. If the number of > subcontexts is equal to maxDepth, stop processing. The maxDepth attribute > should be optional of course, and have a default value like 911or so. The > stack argument could be used to check the amount of subcontexts processed. > Because I want to be able to dump the configuration for debugging purposes, > this item is of somewhat importance to me. > I tested this in 1.2 at work, so I cannot easily test this against 1.4. But > as the code of 1.4 seems to be more or less the same, I think the problem > still exists. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
