[jira] [Commented] (SVN-4622) revert as root always notifies for files

    [ https://issues.apache.org/jira/browse/SVN-4622?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17618000#comment-17618000 ] 

Chris Pickett commented on SVN-4622:
------------------------------------

This commonly occurs under Cygwin if the owner of a file somehow becomes Administrators instead of the regular Cygwin user.  "chown <user> file" fixes it.

> Reverted 'wc/f'
> The function svn_io__is_finfo_read_only() will check the world permissions when invoked with uid=root. A typical umask removes world write so this means that root sees every file as read-only. This causes the revert code to invoke svn_io_set_file_read_write() and notify. However svn_io_set_file_read_write() sets the owner permissions, an operation that succeeds when run as root, and obeys the umask so the world permissions remain read-only.
