/**
|
|
*
|
|
* and yet another idea how to handle file uploads:
|
|
* let the jquery fileupload thing handle as much as possible
|
|
*
|
|
* use singlefileupload
|
|
* on first add of every selection
|
|
* - check all files of originalFiles array with files in dir
|
|
* - on conflict show dialog
|
|
* - skip all -> remember as default action
|
|
* - replace all -> remember as default action
|
|
* - choose -> show choose dialog
|
|
* - mark files to keep
|
|
* - when only existing -> remember as single skip action
|
|
* - when only new -> remember as single replace action
|
|
* - when both -> remember as single autorename action
|
|
* - continue -> apply marks, when nothing is marked continue == skip all
|
|
* - start uploading selection
|
|
*
|
|
* on send
|
|
* - if single action or default action
|
|
* - when skip -> abort upload
|
|
* ..- when replace -> add replace=true parameter
|
|
* ..- when rename -> add newName=filename parameter
|
|
* ..- when autorename -> add autorename=true parameter
|
|
*
|
|
* on fail
|
|
* - if server sent existserror
|
|
* - show dialog
|
|
* - on skip single -> abort single upload
|
|
* - on skip always -> remember as default action
|
|
* - on replace single -> replace single upload
|
|
* - on replace always -> remember as default action
|
|
* - on rename single -> rename single upload, propose autorename - when changed disable remember always checkbox
|
|
* - on rename always -> remember autorename as default action
|
|
* - resubmit data
|
|
*
|
|
* on uplad done
|
|
* - if last upload -> unset default action
|
|
*
|
|
* -------------------------------------------------------------
|
|
*
|
|
* use put t ocacnel upload before it starts? use chunked uploads?
|
|
*
|
|
* 1. tracking which file to upload next -> upload queue with data elements added whenever add is called
|
|
* 2. tracking progress for each folder individually -> track progress in a progress[dirname] object
|
|
* - every new selection increases the total size and number of files for a directory
|
|
* - add increases, successful done decreases, skip decreases, cancel decreases
|
|
* 3. track selections -> the general skip / overwrite decision is selection based and can change
|
|
* - server might send already exists error -> show dialog & remember decision for selection again
|
|
* - server sends error, how do we find collection?
|
|
* 4. track jqXHR object to prevent browser from navigationg away -> track in a uploads[dirname][filename] object [x]
|
|
*
|
|
* selections can progress in parrallel but each selection progresses sequentially
|
|
*
|
|
* -> store everything in context?
|
|
* context.folder
|
|
* context.element?
|
|
* context.progressui?
|
|
* context.jqXHR
|
|
* context.selection
|
|
* context.selection.onExistsAction?
|
|
*
|
|
* context available in what events?
|
|
* build in drop() add dir
|
|
* latest in add() add file? add selection!
|
|
* progress? -> update progress?
|
|
* onsubmit -> context.jqXHR?
|
|
* fail() ->
|
|
* done()
|
|
*
|
|
* when versioning app is active -> always overwrite
|
|
*
|
|
* fileupload scenario: empty folder & d&d 20 files
|
|
* queue the 20 files
|
|
* check list of files for duplicates -> empty
|
|
* start uploading the queue (show progress dialog?)
|
|
* - no duplicates -> all good, add files to list
|
|
* - server reports duplicate -> show skip, replace or rename dialog (for individual files)
|
|
*
|
|
* fileupload scenario: files uploaded & d&d 20 files again
|
|
* queue the 20 files
|
|
* check list of files for duplicates -> find n duplicates ->
|
|
* show skip, replace or rename dialog as general option
|
|
* - show list of differences with preview (win 8)
|
|
* remember action for each file
|
|
* start uploading the queue (show progress dialog?)
|
|
* - no duplicates -> all good, add files to list
|
|
* - server reports duplicate -> use remembered action
|
|
*
|
|
* dialoge:
|
|
* -> skip, replace, choose (or abort) ()
|
|
* -> choose left or right (with skip) (when only one file in list also show rename option and remember for all option)
|
|
*
|
|
* progress always based on filesize
|
|
* number of files as text, bytes as bar
|
|
*
