Generally spoken this is a pretty simple matter:

[number of log entries for this file] == "version number"

Since your requirement is compatible enough that the number of log entries
directly corresponds to the version number, we now at least know that there
is no *extra* state data needed which would need to be stored in database
area.


As an svn semi-expert (insufficiently informed since SvnBridge devel), I
don't know which particular APIs might be available to retrieve this
information in the most direct/efficient manner, though.
You are likely looking for something
which directly returns a shallow "number of log entries"
rather than deep (per-entry) log information...

HTH,

Andreas Mohr
