When the uploaded files have a relative path (that is, when a folder is uploaded) it is first ensured that all the parent folders exist, which is done by trying to create them. When a folder is created in the currently opened folder the file list is updated and a row for the new folder is added. However, this was done too when the folder already existed, which caused the previous row to be removed and a new one added to replace it. For security reasons, some special headers need to be set in requests; this is done automatically for jQuery by handling the "ajaxSend" event in the document. In the case of DAV requests, if the headers are not set the server rejects the request with "CSRF check not passed". When a file or folder is dropped on a folder row the jQuery upload events are chained from the initial drop event, which has the row as its target. In order to upload the file jQuery performs a request, which triggers the "ajaxSend" event in the row; this event then bubbles up to the document, which is then handled by adding the special headers to the request. However, when a folder was dropped on a folder row that folder row was removed when ensuring that the folder exists. The jQuery upload events were still triggered on the row, but as it had been removed it had no parent nodes, and thus the events did not bubble up. Due to this the "ajaxSend" event never reached the document when triggered on the removed row, the headers were not set, and the upload failed. All this is simply fixed by not removing the folder row when trying to create it if it existed already. Signed-off-by: Daniel Calviño Sánchez <danxuliu@gmail.com> |

Running master checkouts
Third-party components are handled as git submodules which have to be initialized first. So aside from the regular git checkout invoking git submodule update --init or a similar command is needed, for details see Git documentation.
Several apps that are included by default in regular releases such as firstrunwizard or gallery are missing in master and have to be installed manually.
That aside Git checkouts can be handled the same as release archives.
Note they should never be used on production systems.
