I'm sorry I should have mentioned that all the points from "Solutions,
Server perspective" down are what I've collected from the various posts.
I'm not familiar with the RailsPort and so I can't really tell about the
But never the less we have to talk about how we could get the
information (either from the API or from any other source) as without
this it won't be possible to write a revert-tool that actually can
revert dirty Changesets (or better: that can revert *all* dirty Changesets).
I'm sorry if this sounds like an attack to you. I know it's not the APIs
job to support weird requests of all kinds, but especially on issue #1
there is *no other way* to get this information.
What I'm asking myself is, if serving such requests will really have
such a large impact on server performance. I'm really sure there won't
be too many hits on these special (history only) calls, do you?
