Having this fix in 1.6.12 would be great.

SWIG: Memory: 413.3 MB virtual private Running time: 3m03s CPU FSFS repository w. SWIG: Memory: 408.9 MB virtual private Running time: 3m04s CPU Based on this I would say that BDB repositories appear to not leak much when using Subvertpy. Everything else leaks quite a lot. Granted, there is a significant CPU overhead in Subvertpy, but I believe its much cleaner API and better memory handling compensate for that. Besides, many people using hgsubversion will have their conversions I/O bound rather CPU bound. -- Dan Villiom Podlaski Christiansen dan...@gmail.com
