Command to edit a committed revision
Example command for revision r4448
$ svn propedit svn:log --revprop -r r4448
hook setup for allowing editing log message
In case you get the following error:
"svn-prop.tmp" 1L, 15C written svn: E175002: DAV request failed; it's possible that the repository's pre-revprop-change hook either failed or is non-existent svn: E175002: Repository has not been enabled to accept revision propchanges; ask the administrator to create a pre-revprop-change hook
Go to you repository hooks directory and follow these steps:
$cd /repo_root_dir/hooks/ $ sudo cp pre-revprop-change.tmpl pre-revprop-change $ sudo chmod a+x pre-revprop-change
Now when you run svn propedit svn:log it should work.
