Re: [PATCH] new feature, lazy sync via export --skipfilesmatchingsize

Hi Julian et al,

Yes, the new 1.7 feature sounds very promising. I was wondering what
WC-NG stands for but I think I get the idea.

I tried sending the rest of this reply earlier and suspect it was
caught in a moderator queue. (( I'm subscribed now; take 2 and
apologies for anyone who has already read this. I suspect that my
.patch files (which I did attach but which did not hit this list)
were stripped because I wasn't subscribed at the time. If the vote
goes positive then I will definitely try attaching them again. ))

I'll tell you the one way in which that might not completely solve
the use-case that I have in mind, and that is doing a series of
partial exports from multiple repositories. Basically I am building
up a server from a series of images that come from different
repositories due to ownership, permission and licensing
limitations. So I might run a series of 10 or 20 exports from
different sections of various repositories, to build up a given
server (e.g. appliance). Using export, there are no conflicts, even
if some of those exports put files into the same target
folders. (Take as a worst-case example, targeting the
c:\windows\system32 folder. )

Would your 1.7 WC-NG feature be okay with a shared .svn folder (e.g.
c:\.svn\ ) with details about exports relating to multiple
repositories? If yes, *great*.

I suspect that non-Windows users would just use yum or equivalent for
my use-case... meanwhile I came up with this process of layering
exports of sections of repositories in order to build up appliances
that are similar in some-but-not-all ways.

For anyone who is feeling +1 about the feature, I'd be interested in
any suggestions for a better name for the flag. The reasoning behind
the verbosity was that people could simultaneously realize the
usefulness (skip large unchanged files) and the danger (what if a
real change did not change the byte size ( bad luck )).

Thank you for your consideration.
