Subversion, binary files, hex editors and file modification time

From: Oliver Paulus <oliver_at_code-project.org>

I have the following problem: If a program like a hex editor does not change the
file modification time SVN does not detect changes made to the file.

I have made some tests with the svn:needs-lock for these binaries - but the
problem remains.

Is there already a solution available?

Why does SVN check the file modification time and does not use a Hash (md5,
sha1, ...) to check if a file was changed? I know that the hash calculation can
be more time expansive.

What do you think about a global or per-file property to say SVN to check these
files with a hash calculation?

I have found some similar topics in some mailing list archives:
