Re: [PATCH] Various little improvements for contrib/client-side/asvn

 From the description given I'm happy to accept these changes so long as
they actually work :-) Some of the changes mentioned have been suggested
for quite some time and I'm glad that someone took the effort to do
them. Work and family commitments (3 yr old and 6 mth old) have
prevented me from following subversion developments. I'm just happy that
there is obviously at least one other person who is still using the script.

Personally I would need to keep with my original asvn script as I still
need to support symlinks. My company wrote our own svn client
application for upgrading our embedded device file systems in the field,
which doesn't need a working copy, this program hasn't been upgraded to
understand symlinks from subversion.

I'm not sure if anyone is interested in our application, we called it
svndelta. If people are let me know and I'll see if I can get it
released. In summary it only supports update, checkout and switch
operations. By not allowing mixed revisions, keyword expansion or eol
modifications we are able to remove the need for a base copy of the
files being checked out. We keep a single version identifier for the
entire filesystem. When an update is performed the working files are
used as reference for the deltas which get applied into a holding
directory. Once all the files are downloaded to the holding directory
they are then applied to the working filesystem so the changes are only
applied once the entire revision is available. Obviously it also
understands the asvn properties for symlinks, devices and ownership. We
have been running this program for a few years now and after performing
around 1000 upgrades we have yet to have a corrupted system.

Thanks for the interest
