`glob` can return FALSE when the directory is empty, instead of an empty array,
causing an error at `foreach`.
"Note: On some systems it is impossible to distinguish between empty match and
an error."
See http://www.php.net/manual/en/function.glob.php -> Return Values
Any error in opening the trashbin directory returns 'true' for isEmpty.
An error is prevented by checking if the directory exists before trying to
open it.
Files app:
- removed file list template, now rendering list from JSON response
- FileList.addFile/addDir is now FileList.add() and takes a JS map with all required
arguments instead of having a long number of function arguments
- added unit tests for many FileList operations
- fixed newfile.php, newfolder.php and rename.php to return the file's
full JSON on success
- removed obsolete/unused undo code
- removed download_url / loading options, now using
Files.getDownloadUrl() for that
- server side now uses Helper::getFileInfo() to prepare file JSON response
- previews are now client-side only
Breadcrumbs are now JS only:
- Added BreadCrumb class to handle breadcrumb rendering and events
- Added unit test for BreadCrumb class
- Moved all relevant JS functions to the BreadCrumb class
Public page now uses ajax to load the file list:
- Added Helper class in sharing app to make it easier to authenticate
and retrieve the file's real path
- Added ajax/list.php to retrieve the file list
- Fixed FileActions and FileList to work with the ajax list
Core:
- Fixed file picker dialog to use the same list format as files app
The versions and trashbin app are now passing "includeMountPoints=false"
to "getFileInfo()" to make sure that the calculated total size doesn't
include mount points like Shared or external storage.
This is because the default call (legacy) used to return the size of
mount points as well.
Fixes#6731
Frontend:
- The files app list now uses ajax calls to refresh the list.
- Added support the browser back button (history API).
- Added mask + spinner while loading file list
Backend:
- Added utility function in core JS for parsing query strings.
- Moved file list + breadcrumb template data code to helper
functions
- Fixed some file paths in trashbin app to be similar to the files app
