Hello han zheng: > When I saw the logging information, I saw a string "fdopen" when I "print" > the req.content. So what is the meaning of the "fdopen" ?
"fdopen" is a Python library type: http://docs.python.org/3/library/os.html?highlight=fdopen#os.fdopen I believe the LAFS gateway is storing the uploaded data, if it is large enough, in a temporary file on disk instead of in RAM. Here is the code in the Twisted HTTP server that does that: http://twistedmatrix.com/trac/browser/trunk/twisted/web/http.py?annotate=blame&rev=36410#L667 It looks like (with current HEAD of Twisted) it does this if the request body is >= 100,000 bytes. The Python standard library "tempfile" module that Twisted uses produces things whose description includes "fdopen": http://docs.python.org/3/library/tempfile.html Regards, Zooko _______________________________________________ tahoe-dev mailing list tahoe-dev@tahoe-lafs.org https://tahoe-lafs.org/cgi-bin/mailman/listinfo/tahoe-dev
