/**
|

|
|
* A lot going on in this function, and some of it is old cruft and some is new cruft
|
||
|
|
* and the entire thing probably needs to be refactored. It started out just storing
|
||
|
|
* files, before we had DAV. It was made extensible to do extra stuff like edit an
|
||
|
|
* existing file or optionally store a separate revision using $options to choose between different
|
||
|
|
* storage models. Along the way we moved from
|
||
|
|
* DB data storage to file system storage.
|
||
|
|
* Then DAV came along and used different upload methods depending on whether the
|
||
|
|
* file was stored as a DAV directory object or updated as a file object. One of these
|
||
|
|
* is essentially an update and the other is basically an upload, but doesn't use the traditional PHP
|
||
|
|
* upload workflow.
|
||
|
|
* Then came hubzilla and we tried to merge photo functionality with the file storage. Most of
|
||
|
|
* that integration occurs within this function.
|
||
|
|
* This required overlap with the old photo_upload stuff and photo albums were
|
||
|
|
* completely different concepts from directories which needed to be reconciled somehow.
|
||
|
|
* The old revision stuff is kind of orphaned currently. There's new revision stuff for photos
|
||
|
|
* which attaches (2) etc. onto the name, but doesn't integrate with the attach table revisioning.
|
||
|
|
* That's where it sits currently. I repeat it needs to be refactored, and this note is here
|
||
|
|
* for future explorers and those who may be doing that work to understand where it came
|
||
|
|
* from and got to be the monstrosity of tangled unrelated code that it currently is.
