Hi *, as there have been complaints lately that tinderbox server and also opengrok are unresponsive despite the server not seeing any CPU load or memory constraints, I thought that maybe the newly activated check-for-updates is to blame here, and indeed it is:
Capturing the dialog with wireshark shows: GET /check.php?pkgfmt=rpm HTTP/1.1 Keep-Alive: Connection: TE, Keep-Alive TE: trailers Host: update.libreoffice.org Accept-Encoding: gzip Pragma: no-cache Accept-Language: de User-Agent: LOdev 3.5 (e40af8c-10029e3-615e522-88673a2-727f724; Linux; X86_64; BundledLanguages=en-US) So it uses Keep-Alive, despite only doing one single request and doesn't close the connection afterwards either. As the server is configured with keep-alive enabled, and a rather short amount of simultaneous clients, the requests pile up during busy periods of the day and the whole thing becomes unresponsive. As the regular outcome of a check-for-updates is only one single response from the update server, LO should issue the request either as plain HTTP/1.0 (that doesn't know keep-alive), or add "Connection: close" to the header parameters to indicate that the connection should be closed after the server did send its reply. Please consider this as stopper for upcomping versions. (the "Connection" field is fishy anyway, HTTP 1.1 only specifies one token, and that token being "close" ( http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.10 ), so not sure what "TE" does here - "Keep-Alive:" while mentioned in RFC 2068 also doesn't make any sense without also providing a parameter, but as keep-alive is not desired here at all...) ciao Christian _______________________________________________ LibreOffice mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/libreoffice
