The previous approach sent the key values twice, which for large sets is
twice as bad.
As an optional feature of this approach multiGet now allows retrieving tuples
in exact order and amount of the requested key values.
Instead of relying on the MariaDB's ON UPDATE CURRENT_TIMESTAMP trigger update
"modified" attributes in Managed_DataObject. Every raw query that needs
adjusting is adjusted, as they won't update "modified" automatically anymore.
The main goal behind this change is to fix "modified" updates on PostgreSQL.
Use $object->sqlValue('NULL') (identical to DataObject_Cast'ing) instead and
fix related issues like (email|sms)settings considering these NULLs as a
false positive for the E-Mail address still being set when it's been removed.
There could also be security implications to the now-disabled approach of
considering 'NULL' strings as SQL NULLs.
The code used to operate under the assumption that MariaDB doesn't support
quoting identifiers. Not only is that not exactly true, but MariaDB has
reserved keywords that cannot be used as table or column names unquoted.
We're also now using $config['image']['jpegquality'] to determine the
quality setting for resized images.
To set Avatar max size, adjust $config['avatar']['maxsize']
The getAvatar call now throws exceptions too. Related changes applied.
Now let's move Profile->avatarUrl to the Avatar class!
Memcached_DataObject now defines
* pkeyGetClass to avoid collision with Managed_DataObject pkeyGet
* getClassKV to avoid collision with Managed_DataObject getKV
I used this hacky sed-command (run it from your GNU Social root, or change the first grep's path to where it actually lies) to do a rough fix on all ::staticGet calls and rename them to ::getKV
sed -i -s -e '/DataObject::staticGet/I!s/::staticGet/::getKV/Ig' $(grep -R ::staticGet `pwd`/* | grep -v -e '^extlib' | grep -v DataObject:: |grep -v "function staticGet"|cut -d: -f1 |sort |uniq)
If you're applying this, remember to change the Managed_DataObject and Memcached_DataObject function definitions of staticGet to getKV!
This might of course take some getting used to, or modification fo StatusNet plugins, but the result is that all the static calls (to staticGet) are now properly made without breaking PHP Strict Standards. Standards are there to be followed (and they caused some very bad confusion when used with get_called_class)
Reasonably any plugin or code that tests for the definition of 'GNUSOCIAL' or similar will take this change into consideration.
This should resolve the issues darkip was reporting with user_im_prefs entries returning null immediately after insertion (seen with memcached off, so it was happening even with the built-in in-process cache in the Cache base class).
What was happening was that the initial pkeyGet() would end up saving a negative cache entry under the form with the fields sorted in the key, as via multicacheKey():
'statusnet:blaguette:user_im_prefs:screenname,transport:brionv,sms' => 'N;'
then we'd do an insert() on the new entry, saving cache entries for the non-sorted key names returned by _allCacheKeys():
'statusnet:blaguette:user_im_prefs:transport,screenname:sms,brionv' => 'O...'
'statusnet:blaguette:user_im_prefs:user_id,transport:1234,sms' => 'O...'
but the next query via pkeyGet() still saw the negative lookup cache from before, and came back with null.
Now, _allCacheKeys() sorts the fields in the keys by using the same key-builder function, and queries pick up the same thing you just inserted. :)
