d85b8894 | 14 | \section cserrors Errors and client side |
edce4d98 | 15 | * |
63be0a78 | 16 | \par Problem the first: |
17 | * the store entry is no longer authoritative on the | |
edce4d98 | 18 | * reply status. EBITTEST (E_ABORT) is no longer a valid test outside |
19 | * of client_side_reply.c. | |
20 | * Problem the second: resources are wasted if we delay in cleaning up. | |
21 | * Problem the third we can't depend on a connection close to clean up. | |
9e008dda | 22 | * |
63be0a78 | 23 | \par Nice thing the first: |
9e008dda | 24 | * Any step in the stream can callback with data |
edce4d98 | 25 | * representing an error. |
26 | * Nice thing the second: once you stop requesting reads from upstream, | |
27 | * upstream can be stopped too. | |
28 | * | |
63be0a78 | 29 | \par Solution #1: |
30 | * Error has a callback mechanism to hand over a membuf | |
9e008dda | 31 | * with the error content. The failing node pushes that back as the |
edce4d98 | 32 | * reply. Can this be generalised to reduce duplicate efforts? |
33 | * A: Possibly. For now, only one location uses this. | |
34 | * How to deal with pre-stream errors? | |
35 | * Tell client_side_reply that we *want* an error page before any | |
36 | * stream calls occur. Then we simply read as normal. | |
63be0a78 | 37 | * |
38 | * | |
d85b8894 | 39 | \section pconn_logic Persistent connection logic: |
63be0a78 | 40 | * |
41 | \par | |
42 | * requests (httpClientRequest structs) get added to the connection | |
43 | * list, with the current one being chr | |
9e008dda | 44 | * |
63be0a78 | 45 | \par |
46 | * The request is *immediately* kicked off, and data flows through | |
47 | * to clientSocketRecipient. | |
9e008dda | 48 | * |
63be0a78 | 49 | \par |
50 | * If the data that arrives at clientSocketRecipient is not for the current | |
51 | * request, clientSocketRecipient simply returns, without requesting more | |
52 | * data, or sending it. | |
53 | * | |
54 | \par | |
4a4fbcef | 55 | * ConnStateData::kick() will then detect the presence of data in |
9e008dda | 56 | * the next ClientHttpRequest, and will send it, restablishing the |
63be0a78 | 57 | * data flow. |

527 | * when connection-auth credentials change unexpectedly or are unset. | |
528 | * | |
529 | * 1) auth helper released from any active state | |
530 | * | |
531 | * They can only be reserved by a handshake process which this | |

533 | * This prevents helpers hanging when their connections close. | |
534 | * | |
535 | * 2) pinning is expected to be removed and server conn closed | |
536 | * | |
537 | * The upstream link is authenticated with the same credentials. | |
538 | * Expecting the same level of consistency we should have received. | |
539 | * This prevents upstream being faced with multiple or missing | |
540 | * credentials after authentication. | |
541 | * NP: un-pin is left to the cleanup in ConnStateData::swanSong() | |
542 | * we just trigger that cleanup here via comm_reset_close() or | |
543 | * ConnStateData::stopReceiving() | |
544 | * | |

546 | * | |
547 | * This prevents attackers injecting requests into a connection, | |
548 | * or gateways wrongly multiplexing users into a single connection. | |
549 | * | |
550 | * When credentials are missing closure needs to follow an auth | |
551 | * challenge for best recovery by the client. | |
552 | * | |
553 | * When credentials change there is nothing we can do but abort as | |
