Faster svn:externals detection
Hi,
On the TortoiseSVN mailing list I asked for a feature that would
explicitly show svn:externals directories when browsing through a
repository, i.e. by displaying those folders in a different colour.
Currently TSVN's Repo(sitory) Browser doesn't show externals. Only when
you look at the properties of the directory you can find out if it
contains externals.
Stefan, TSVN's primary coder, responded that he'd like such a feature
too. But he said it could only be implemented if TSVN looked at the
properties of each directory in the repository, which would heavily slow
down the browsing process.
So I think from a TSVN perspective there's no easy way to solve this.
But maybe something can be added to Subversion itself? Would it be
possible for Subversion to indicate to a client that a folder contains
externals, without requiring the extra round-trip to fetch the
properties?
Greetings,
Leon Zandman

Yes, but the way he described it, it sounded like it combined a display
of those directories from the wc, plus the ones that had svn:externals,
and made those with svn:externals have a different color.
If it's really trying to gang-lookup all the svn:external properties in
a repository directory (IE a url), this won't help at all.

This is an svn ls against the repository scenario. Doesn't your proposal
only speed up the WC?
I guess they are asking that the API underneath svn ls have an ability to
communicate the svn:externals property. I believe the lock information
was recently added to this API, so I imagine that is partly inspiring this
request.

The wc-propcaching branch is adding code to do just this.
In fact, i posted a patch this morning that caches whether this property
exists or not so that it's not expensive to try to get it on every
directory.
