Subject [jira] Commented: (HARMONY-4754) [classlib] FilePermission incorrect canonical path
Date Fri, 07 Sep 2007 16:30:31 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-4754?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12525771

Mark Hindess commented on HARMONY-4754:
---------------------------------------

Oops.  Ignore that comment.  Doing something silly (the RI forks (or clones a new thread)
and I had omitted the -f option on strace.)

> If called with a path ending in "-" or "*", java.io.FilePermission calls  File.getCanonicalPath
with the "-" or "*" still appended.  This is incorrect (and produces very odd results if "-"
or "*" exists - perhaps as a symlink to some completely different tree).
> For example, if you do:
>   mkdir test
>   ln -s /tmp test/-
>  then (new FilePermission("test/-", "read")).implies(new FilePermission("/tmp/file",
"read")
> is true and (new FilePermission("test/-", "read")).implies(new FilePermission("test/file",
"read") is false where as on the RI it is the opposite way around since the '-' symlink is
(correctly) ignored.
