I'm a longtime user of WebWare. I just stumbled over some pretty strange problem. The Application running on Webware is a kind of Document Management system that can contain quite huge files (ISO images). When somebody is downloading such a file and cancels the download, the application eats up more and more memory. It looks like the application tries to deliver the content, but, instead of delivering it to the client (who's not longer there), caches everything in memory. This is the newest version of WebWare.
I've done the following change: In WebKit/ThreadedAppServer.py 741 def flush(self): 742 """Flush stream. 743 744 Calls `ASStreamOut.ASStreamOut.flush`, and if that returns True 745 (indicating the buffer is full enough) then we send data from 746 the buffer out on the socket. 747 748 """ 749 result = ASStreamOut.flush(self) 750 if result: # a True return value means we can send 751 reslen = len(self._buffer) 752 sent = 0 753 while sent < reslen: 754 try: 755 sent += self._socket.send( 756 self._buffer[sent:sent+8192]) 757 except socket.error, e: 758 if e[0] == errno.EPIPE: # broken pipe 759 pass 760 elif hasattr(errno, 'ECONNRESET') \ 761 and e[0] == errno.ECONNRESET: 762 pass 763 else: 764 print "StreamOut Error: ", e 765 break 766 self.pop(sent) I've changed line 759 from 'pass' to 'raise', which now gives ugly tracebacks in the logs, but other than that, does what should happen anyway: cancel the download. Stephan P.S.: I know this is quite a political issue, but is there a chance to change from tabs to spaces in Webware code? ------------------------------------------------------------------------- Take Surveys.
