* Possible fix for #5470:
- $data is not an object like stdClass but an array
- newer PHP versions doesn't allow cross-access like following:
$object['foo'] = 123;
$array->foo = 123;
- added type-hints for private methods for above cases
- used `if (empty($foo)) instead of just `if ($foo)` preventing some nasty
E_NOTICE
- added some empty lines for better readability
* Rewrite:
- mixture of object/array was here, causing under newer PHP versions some E_NOTICE
- this has been now finally fixed by converting any `object` type to an
associative `array`
- also changed `is_object()` to `is_array()`
- $data is not an object like stdClass but an array
- newer PHP versions doesn't allow cross-access like following:
$object['foo'] = 123;
$array->foo = 123;
- added type-hints for private methods for above cases
- used `if (empty($foo)) instead of just `if ($foo)` preventing some nasty
E_NOTICE
- added some empty lines for better readability
* Use "LEFT JOIN" to always fetch the item. Needed for update routines.
* New conversion routine that now covers every item
* Post update is now activated
* We now use a hash based upon RIPEMD-320 for content and activity
* The hash doesn't contain the plink anymore
* Legacy item fields are now "null"able
* New hash function for a server unique item hash
* Introduction of the legacy mode (usage of old item fields)
* Code simplification
* We don't need the "uri" fields anymore in item-activity and item-content
* Use the "created" and not the "received" date for the hash
* Avoiding several notices
* Some more warnings removed
* Improved uri-hash / Likes on Diaspora are now getting a creation date
* Corrected the post update version
* Ensure an unique uri-hash
* Don't delete orhaned item data at the moment
* Partly reworked, due to strange behaviour
* Some more parts reworked
* Using the uri currently seems to be more reliable
* Using the uri here as well
* Use the hash values again
* Grouped item fields in different categories
* Notices again
* use the gravity (we always should)
* Added hint for disabled post updates
* Notices ...
* Issue #5337: Personal notes are displayed again
* Use the gravity again
* Some more warnings removed
* Even more warnings ...
* Will it ever end? ;-)
* Avoid warning in dbstructure
* Origin and OStatus ...
* There are more warnings solved ... yeah!
* And again ...
* We are not done yet
* And more ...
* And some new places ...
* And more in the feeds
* Avoid some more
* And some backend stuff
* Notifications cleared
* Some more stuff
* and again ...
* It's getting fewer ...
* Some warnings had been hidden in the notifications
* Fix the fix
* And another missing one ...
* We need the owner here, not the user
* Forgotten user
* And more ...
* And some more warnings disappeared ...
* Some more frontend warnings
* Some backend warnings removed
* Fixed sidebar for "vier"
* And more ...
* Some more ...
* And something for "remote self"
* Am I stuck in an endless loop?
* Fix: Clear tag and file field on update
* Preset page content
- Changed parameter order to save space
- Refactor select_timezone into Temporal::getTimezoneSelect
- Refactor field_timezone into Temporal::getTimezoneField
