Hi again Philip,
Sorry, I was a bit too hasty in saying this was machine dependent.
Your test case does respect the umask on all of the machines I am
trying it on, but on real life repositories the bug occurs as I
described (which is how I was reproducing it).
Here is a sequence of commands that should reproduce the bug for you:
[Cathy_at_localhost scratch]$ svn co
http://svn.apache.org/repos/asf/subversion/trunk subversion >
/dev/null
[Cathy_at_localhost scratch]$ cd subversion/
[Cathy_at_localhost subversion]$ echo blah >> INSTALL
[Cathy_at_localhost subversion]$ svn diff > patch
[Cathy_at_localhost subversion]$ svn revert INSTALL
Reverted 'INSTALL'
[Cathy_at_localhost subversion]$ ls -l INSTALL
-rw-rw-r--. 1 Cathy Cathy 63057 Nov 22 03:29 INSTALL
[Cathy_at_localhost subversion]$ umask 070
[Cathy_at_localhost subversion]$ svn patch patch
U INSTALL
[Cathy_at_localhost subversion]$ ls -ls INSTALL
68 -rw-------. 1 Cathy Cathy 63062 Nov 22 03:29 INSTALL
This is just a guess to be verified later: it may be that the bug only
occurs if a file has an EOL property specified.
Thanks,
Cathy
