All reloadCallback must return either true for success or false in case
of failure / non-existing folder.
Some file lists only have a root folder (favorite, shares), so restrict
the path to that to avoid having a wrong path in the breadcrumbs.
This makes it possible for the recipient to still trigger the sidebar
and share tab to see information about the share.
In the case where the file is not shared and no permissions exists, no
action icon will be displayed.
Tab heads are not rendered if only one tab.
The tab contents is updated on-demand. This means that if a tab is not
visible it is not rendered at first. If the tab was already rendered
through switching, its model will not get updated until the next time it
becomes visible. This will prevent needless rerendering of invisible tab
contents, especially considering that some tabs might need extra ajax
requests.
The favorite icon in the sidebar now triggers the file action and also
updates itself according to the model's state when triggered from the
file row.
The thumbnail triggers the default action.
Currently only one FileInfoModel is used for the selection and state
synchronization between views.
FileList reload now auto-closes the sidebar.
In some corner cases, an outgoing share exists but sharing is not
allowed for the current user. This would cause the file list to break
because the static text could not be rendered as the owner was
undefined.
We need to set the size of the preview using the devicePixelRatio and use that as arguments when using the preview endpoint or that endpoint will use the default 36x36 and thumbnails will be blurry on high DPI devices
IE 9 and below do not provide window.btoa and there is currently no way
to generate base64 strings without introducting further dependencies.
So for now the solution is to fall back to the ugly picture mode for
text files whenever IE <= 9 is used.
`params` in the `OC.generateUrl` function call only replaces all specified occurences of a key just like the l10n PHP functionality does.
This means that to build a query string we have to use `OC.buildQueryString` instead of the params parameters.
Fixes https://github.com/owncloud/core/issues/16336 which is a regression introduced with 58a87d0bab of https://github.com/owncloud/core/pull/15652.
Without this fix downloading single files from a public shared folder is not possible.
