That's why I suggest to put in a date. It has one advantage over a
generic number and that is that we as humans are better able to
perform useful interpretations.
The numbers are on a time scale (on svn at least). The unit is not
seconds, nanoseconds, or whatever, but number of commits, which is a
better indication on how much different two revisions might be. Of
course, it isn't as good when branches are involved (the branch may be
out of date and the commit won't change that), but that was already the
case with svn and never caused problems. Of course, we'll get more
branches in the system, but is that really a problem ? We know at some
point someone will have to actually dig out the changelog, but the
revision number is easy to use for quick overview.
As you say, with the branches in SVN, the revision numbers don't offer any
clear information. With more branches (cheap branching being one of the
motivations for switching to a DVCS), SVN-style revision numbers will lose
even more of their meaning. IMO, it doesn't make sense to try to hack a
property of centralized VCSs on a DVCS. It is fundamentally incompatible!
Niels (hg) and Oliver (git) have both proposed identifiers that provide as
much information as you can realistically find out about a particular
build. In addition, both git and hg offer plenty of functions to locate
and visualize a particular changeset. In addition, services such as GitHub
offer the possibility to visualize the history of forks. Just let SVN go
and embrace the new technologies.
Tons of open source projects have switched to distributed version control.
Surely it can't be that bad? If you're afraid of change, there's no reason
to switch the a DVCS.
