python - How to NOT load whole file into memory during upload -

-

The script below is being used to upload an upload file to a directory, but I need to address two issues. One is that how can I save the entire file from loading in memory and how to set the maximum size for the second upload file?

Is it possible to continuously read the file and what is the dump to read it in the file until the upload is complete? The function seems to load the entire file in the memory. In the tutorial, they have indicated that bottle import bottles, requests, runs, feedback, Path, default_app, static_file app = 

  to  .read ()  bottle () @route ('/ upload', method = 'post') def Upload_file ():. Try function_name = sys._getframe () f_code.co_name: upload = request.files.get ("upload_file") if not uploaded: return to another "nothing to upload": #Get file_name and extension file_name, Ext = os.path.splitext (upload.filename) if in ('.exe', '.msi', '.py') eXT: Return "File extension is not allowed." #Determine folder to save save_folder = save "if not so os.path.exists (save_folder /tmp/{folder}".format(folder='external_files')): os.makedirs (save_folder) #Determine FILE_PATH FILE_PATH =" { Path} / {time_now} _ {file} ". Upload format (path = save_folder, file = upload.filename, timestamp = time_now) upload #Save quantity in upload.save (FILE_PATH file, write up = false, chunk_size = 1024) "file successfully saved {0} {1} For '{2}'. " Except for the keyboardInterrupt format (file_name, ext, save_folder): logger.info ('% s:'% (function_name)., "Someone pressed CNRL + C"): logger.error ('% s:'% ( Function_name, exc_info = true) print ("exception occurred 111 location:.% S"% (function_name)) Finally: if passed __name__ == '__main__': run (host = "localhost", port = 8080, reloador = True, Debug = True) Second: App = Day Fault_app ()

I even tried to file one. Write but the same matter. The file is being read in memory and the machine has been hanged. Whereas true: datachunk = upload.file.read (1024) If the datacent is not in the: file_to_write.write (break) file: file_to_write = open ("% s"% (output_file_path), "wb") Datachunk)

Regarding this, I have seen that property where many claims can set a maximum file upload size. I have tried to set it up, but it does not seem that all the files cause no difference due to the size.

Note that I want to be able to get office documents which can be plain with their extensions or zipped with a password.

Using Python 3.4 and Bottle 0.12.7

Actually, you < Code> want to upload. Reed (1024) In a loop, something like this (untested): 

  open (file_path, 'wb') with dest: chunk = upload.read (1024) while Chuck: Dest.write (Chuck) Chuck = Upload. (Do not call  on  open , it's already open for you.)

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
