[jira] [Commented] (VELTOOLS-146) LinkTool.relative(url) and LinkTool.absolute(url) improperly handle URLs with query strings or anchors

["Nathan Bubna (JIRA)" <de...@velocity.apache.org>]

    [ https://issues.apache.org/jira/browse/VELTOOLS-146?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13071786#comment-13071786 ] 

Nathan Bubna commented on VELTOOLS-146:
---------------------------------------

Actually, instead of creating a setFromURI that doesn't override actual values with null ones, i think there is no good reason that setFromURI should ever do that.  So we should just adapt setFromURI to have a lighter touch and have relative(url) and absolute(url) use that.

> It was unintentionally changed, in part because i wasn't aware that forwards could/would contain query strings.  Basically, setForward passes the url to absolute(url) which would correctly handle absolute urls with query strings but treats relative urls as merely paths, without parsing out anchors or query strings. 
> I think we should adapt both $link.relative($url) and $link.absolute($url) to accept paths with query strings and anchors.  This probably will require a setFromURI(url, withoutOverriding) adapted from what absolute($url) does for actual absolute URIs.
