 | |
|  *
 | |
|  * @note 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.
