I am not sure where to report such issues, so I'll post it here. Please advise if another list is more appropriate.
When I committed Lib/datetime.py to svn, I made sure that it was done in a way that preserved the history of that file going back to 2002. However, hg log of this file starts with my commit about a year ago. Is it possible to re-add the old history? The history of datetime.py is very helpful for understanding various design decisions implemented in that module. This history is discussed in various issues on the tracker (see for example, issue2267) and these discussions now have broken links.
