Realname and OG (organic groups) seem to conflict. With realname enabled, all non-super users will be hung after a single member attempts to join (subscribe) or remove (unsubscribe) from a group. Once the super user accesses several pages (I have not been able to find a pattern) all is well again until the next member attempts to subscribe or unsubscribe. No errors are logged. The website appears totally non-responsive to the end user, though a PHP dubugger shows that Drupal is executing.

I've also opened an issue for the og module 1341626 since I cannot determine if this is an og problem or a realname problem.

I am making a little progress. The problem appears to be an infinite recursion issue. Attached is a call stack (most recent calls at top). The area highlighted by the red rectangle keeps repeating. I stopped it on the 46th iteration. I don't yet understand the problem.

This is caused by a loop, though I do not know enough to assign fault.

  1. It begins with og.module (287) in the user_load_multiple function.
  2. This eventually causes a user entity to be loaded
  3. This will cause the hook_user_load to be driven for realname.
  4. Reaname performs an update, triggering a token_replacement.
  5. This eventually drives a hook_field_access which og_field_access has implemented.
  6. og_filed_access then eventually causes an og_load_entity.
  7. This starts another entity_load, thus begin the recursive loop.

This is locking out other members. This seems to be a major issue. Normal>>Major ??

I can confirm this behaviour. Similar error when filling in realname on user registration pages:

Here is the hack that I used. I had created a field named "field_displayname" which I associated with the user. This hack tests for that name in the og_field_access_field_access function. If the name matches, it returns true since OG should not care about this field. This stops the recursive loop for me.

Edit: I should note that this is an OG patch, not a realname patch.

I had the error on the user pages. My really bad fix:

Disable in the funtion realname_update
//module_invoke_all('realname_update', $realname, $account);

I'm unable to reproduce this bug with the following steps:

1) Fresh Drupal install with OG 7.x-2.x dev
2) Define name_first and name_last fields.
3) Configure RealName to use [user:field_name_first] [user:field_name_last] for the user token.
4) Create a public group
5) Create a Bob Jones user
6) Log in as Bob Jones
7) Join a public group

Perhaps this is only reproducible with OG-7.x-1.x?
