Re: [habari-dev] Re: don't know what to do with error "InvalidArgumentException: Bitmask cannot get non-existent flag"

You said you were using .8. The upgrade to 0.9 should be pretty easy, can you set up a separate test copy and try dropping in the new system directory and see if the error persists?

Hey all,

I suddenly got this error while working on a habari install of version .8 :

InvalidArgumentException: Bitmask cannot get non-existent flag in /var/www/virtual/one/html/system/classes/bitmask.php line 150

It's only appearing when I'm logged in as the admin account, rest of site and other accounts work fine.

.. As I didn't want to dive into which of my newest changes in the source code of some of my plugins might have caused this message, I simply hard-resetted via git to the previously ok version, but even then nothing changed. I re-started the PHP interpreter, but that also changed nothing.

Does anyone have any ideas as to what might be the problem?

Thanks,

Valentin

This error is caused when attempting to access a flag on a bitmask that
doesn't exist. For example, if you have a Habari permission bitmask
named $access, which only has the flags "read,edit,delete,create" on it,
and you tried to do this:

if($access->not_present) {...}

It would throw the exception mentioned.

This can also happen if some variable is defined as a Bitmask, but the
Bitmask in question never had its flags set:

$bitmask = new Bitmask();
if($bitmask->foo) {...} // Causes an exception for any "foo"

To debug this, you'd need to see a stack trace to find out what line in
the code causes the exception to be thrown. Check out this page in the
wiki for tips on how to display the call stack when there are errors:

If you find out what code is doing it, and need more help, come on back.
