Subject: Re: Svn rename doesn't copy custom properties
OK, so it gets stranger...
I admit I changed the property names a bit to simplify them. When I ran the simplified names, it does work.
Here's the exact example that does not work:
c:\Project_files\sandbox_v2>svn pl -v AAAAA.txt
Properties on 'AAAAA.txt':
pebls:plcm
Test_at_4575
pebls:sha1
8cd8818d6b4f5edcb8b6e25cdf471af62bca403c
c:\Project_files\sandbox_v2>svn rename AAAAA.txt AAAAAA.txt
A AAAAAA.txt
D AAAAA.txt
c:\Project_files\sandbox_v2>svn pl -v AAAAAA.txt
c:\Project_files\sandbox_v2>svn pl -v REN.txt
