Bill,
I've been trying to reproduce what you outlined in your last e-mail.
So I had four dirs in a repos
******
dir1/
dir1/file1
dir2/bunch-o-files
dir3/bunch-o-files
dir4/file1
******
svn cp dir1 dir4 yields
svn up
dir1/
dir1/file1
dir2/bunch-o-files
dir3/bunch-o-files
dir4/file1
dir4/dir1/file1
******
vim dir1/file1 and add line.
svn up
dir1/
dir1/file1 ** hass in fact changed as verified by a svn co to another
location
dir2/bunch-o-files
dir3/bunch-o-files
dir4/file1
dir4/dir1/file1 ** Still the same. A Tag right?
******
vim dir4/file1 add a line.
svn up
dir1/
dir1/file1
dir2/bunch-o-files
dir3/bunch-o-files
dir4/file1 ** has the new content
dir4/dir1/file1 ** Still the same content as before
******
cd dir4
svn mv dir1 tag1wasdir1
svn ci
dir1/
dir1/file1
dir2/bunch-o-files
dir3/bunch-o-files
dir4/file1 *** still has the new content
dir4/dir1/ *** empty in wc; but gone when svn up issued in anther location
*******what did I do wrong with my move?
dir4/tag1wasdir1/file1 ** *Still the same content as was in the now
renamed dir1 before
*******
rmdir dir4/dir1/
svn update
dir1/
dir1/file1
dir2/bunch-o-files
dir3/bunch-o-files
dir4/file1 *** still has the new content
dir4/dir1/ *** this guys stays gone. Cool!
dir4/tag1wasdir1/file1 ** *Still the same content as before
*******
vim dir4/tag1wasdir1/file1 add a line.
svn update
dir1/
dir1/file1
dir2/bunch-o-files
dir3/bunch-o-files
dir4/file1
dir4/dir1/
dir4/tag1wasdir1/file1 HAs the new stuff This guy is now a branch right?
*******
So I assume that something is bad inside the FS based on what you guys are
saying.
ALSO:
Something else that confused me:
I was reading issues 653 and 654.
I must confess I got stuck on the first sentence of 654.
"Right now, we use a representation for NodeRevIDs which is unbounded in
length."
I'm still trying to figure out how NodeRevIDs have unbounded length.
So:
- "100" is a node id.
- "100.10" is a node revision id, referring to revision 10 of node 100.
- "100.10.3" is a node id, referring to the third branch based on
revision 10 of node 100.
- "100.10.3.4" is a node revision id, referring to revision 4 of
of the third branch from revision 10 of node 100.
And so on.
Does this notation continue on like 100.10.3.4.1.1?
In looking at some code I thought it could only be the 100.10 or the
100.10.3.4 case. I know I saw some code checking
for those two cases. I can't remember what for.
What am I missing here?
Thanks again.
