svn:externals with a fixed revision

[Matthew Gregory <ma...@nogsnet.com>]

Hi All,

This is my first post to this mailing list as I've only just started to 
use SVN. I must say I'm getting on really well with it. I have a 
question about svn:extenals though.

I've setup the svn:externals property so it has this: /"qooxdoo-sdk 
-r16997 
http://qooxdoo.svn.sourceforge.net/svnroot/qooxdoo/trunk/qooxdoo" /and 
it works as expected. The only thing I can't understand is when I do an 
update it always goes to qooxdoo.svn.sourceforge.net to check for 
updates. Surely it could just see that I already have r16997 locally 
unchanged and skip this? Or am I missing something?

Thanks!
Matt

So one thing you need to know is you have to do "reply all" to keep it
on the list.

Ok I thought that might be the case.  I forgot the more obvious answer
though, update has a --ignore-externals switch.

That said, keep with the @1234 syntax to guarantee that if something
gets moved, you still end up getting the tree you expect.

whoops I meant that's *not* guaranteed to be constant

http://svn.example.com/trunk -r123 is guaranteed to be the same on
Monday as it is on Tuesday!  That's because there's an implicit @HEAD ie
http://svn.example.com/trunk@HEAD -r123

but
http://svn.example.com/trunk@123 should always remain constant.

Welcome to the spooky world of peg revisions.

and here's a long discussion about it

However, changing to that syntax probably won't stop it contacting the
server but you could give it a try.
