d85b8894 | 35 | \section cserrors Errors and client side |
edce4d98 | 36 | * |
63be0a78 | 37 | \par Problem the first: |
38 | * the store entry is no longer authoritative on the | |
edce4d98 | 39 | * reply status. EBITTEST (E_ABORT) is no longer a valid test outside |
40 | * of client_side_reply.c. | |
41 | * Problem the second: resources are wasted if we delay in cleaning up. | |
42 | * Problem the third we can't depend on a connection close to clean up. | |
9e008dda | 43 | * |
63be0a78 | 44 | \par Nice thing the first: |
9e008dda | 45 | * Any step in the stream can callback with data |
edce4d98 | 46 | * representing an error. |
47 | * Nice thing the second: once you stop requesting reads from upstream, | |
48 | * upstream can be stopped too. | |
49 | * | |
63be0a78 | 50 | \par Solution #1: |
51 | * Error has a callback mechanism to hand over a membuf | |
9e008dda | 52 | * with the error content. The failing node pushes that back as the |
edce4d98 | 53 | * reply. Can this be generalised to reduce duplicate efforts? |
54 | * A: Possibly. For now, only one location uses this. | |
55 | * How to deal with pre-stream errors? | |
56 | * Tell client_side_reply that we *want* an error page before any | |
57 | * stream calls occur. Then we simply read as normal. | |
63be0a78 | 58 | * |
59 | * | |
d85b8894 | 60 | \section pconn_logic Persistent connection logic: |
63be0a78 | 61 | * |
62 | \par | |
63 | * requests (httpClientRequest structs) get added to the connection | |
64 | * list, with the current one being chr | |
9e008dda | 65 | * |
63be0a78 | 66 | \par |
67 | * The request is *immediately* kicked off, and data flows through | |
68 | * to clientSocketRecipient. | |
9e008dda | 69 | * |
63be0a78 | 70 | \par |
71 | * If the data that arrives at clientSocketRecipient is not for the current | |
72 | * request, clientSocketRecipient simply returns, without requesting more | |
73 | * data, or sending it. | |
74 | * | |
75 | \par | |
9e008dda AJ |
76 | * ClientKeepAliveNextRequest will then detect the presence of data in |
77 | * the next ClientHttpRequest, and will send it, restablishing the | |
63be0a78 | 78 | * data flow. |

778 | * for all requests on a connection once they have been setup. | |
779 | * There are several things which need to happen to preserve security | |
780 | * when connection-auth credentials change unexpectedly or are unset. | |
781 | * | |
782 | * 1) auth helper released from any active state | |
783 | * | |
784 | * They can only be reserved by a handshake process which this | |
785 | * connection can now never complete. | |
786 | * This prevents helpers hanging when their connections close. | |
787 | * | |
788 | * 2) pinning is expected to be removed and server conn closed | |
789 | * | |
790 | * The upstream link is authenticated with the same credentials. | |
791 | * Expecting the same level of consistency we should have received. | |
792 | * This prevents upstream being faced with multiple or missing | |
793 | * credentials after authentication. | |
794 | * NP: un-pin is left to the cleanup in ConnStateData::swanSong() | |
795 | * we just trigger that cleanup here via comm_reset_close() or | |
796 | * ConnStateData::stopReceiving() | |
797 | * | |
798 | * 3) the connection needs to close. | |
799 | * | |
800 | * This prevents attackers injecting requests into a connection, | |
801 | * or gateways wrongly multiplexing users into a single connection. | |
802 | * | |
803 | * When credentials are missing closure needs to follow an auth | |
804 | * challenge for best recovery by the client. | |
805 | * | |
806 | * When credentials change there is nothing we can do but abort as | |
807 | * fast as possible. Sending TCP RST instead of an HTTP response | |
808 | * is the best-case action. | |
