upgrade_cleanup_unwanted_block_contexts

(

$

contextidarray

)

This function is used as part of the great navigation upgrade of 20090828 It is used to clean up contexts that are unique to a blocks that are about to be removed.

Look at blocklib.php::blocks_delete_instance() the function from which I based this code. It is important to mention one very important fact before doing this I checked that the blocks did not override the block_base::instance_delete() method. Should this function ever be repeated check this again

upgrade_fix_incorrect_mnethostids

(

)

This function will fix the status of the localhost/all records in the mnet_host table checking they exist and adding them if missing + redefine CFG->mnet_localhost_id and CFG->mnet_all_hosts_id if needed + update all the users having non-existent mnethostid to correct CFG->mnet_localhost_id

Implemented because, at some point, specially in old installations upgraded along multiple versions, sometimes the stuff above has ended being inconsistent, causing problems here and there (noticeably in backup/restore). MDL-16879

Get current $CFG/mnet_host records

By wwwroot

By empty wwwroot

Create localhost_host if necessary (pretty improbable but better to be 100% in the safe side) Code stolen from mnet_environment->init

Get the ip of the server

SERVER_ADDR is only returned by Apache-like webservers

Create all_hosts_host if necessary (pretty improbable but better to be 100% in the safe side) Code stolen from mnet_environment->init

Compare old_mnet_localhost_id and current_mnet_localhost_host

Different = problems

Update $CFG->mnet_localhost_id to correct value

Delete $old_mnet_localhost_id if exists (users will be assigned to new one below)

Compare old_mnet_all_hosts_id and current_mnet_all_hosts_host

Different = problems

Update $CFG->mnet_localhost_id to correct value

Delete $old_mnet_all_hosts_id if exists

Finally, update all the incorrect user->mnethostid to the correct CFG->mnet_localhost_id, preventing UIX dupes

Give upgrade at least 60 more seconds
