Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: Pathfinder - compiler Group: None Status: Open Priority: 5 Private: No Submitted By: Jan Rittinger (tsheyar) Assigned to: Nobody/Anonymous (nobody) >Summary: XQ: Garbage Collector Initial Comment: Until now I still wasn't aware that some time ago the Boehm garbage collection library was removed from the pf sources. I'd like to have it back :) Perhaps a new version will work with MonetDB. The reason for my request is that most queries that are bigger than 2 pages of XQuery run out of memory during algebraic optimization. (Every rewrite introduces new nodes, new properties, etc.) An alternative I could live (at least for the time being) is to extend the pf_allocator struct to store also a marker. Each PFmalloc invocation could then have an additional optional marker argument and a corresponding call of PFfree(marker) would free all memory that was marked during malloc with this marker value. I however prefer the first variant (adding a real garbage collection library) as this is certainly less error-prone. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=482471&aid=1620113&group_id=56967 ------------------------------------------------------------------------------ Join us December 9, 2009 for the Red Hat Virtual Experience, a free event focused on virtualization and cloud computing.
