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. |
