d85b8894 | 38 | \section cserrors Errors and client side |
edce4d98 | 39 | * |
63be0a78 | 40 | \par Problem the first: |
41 | * the store entry is no longer authoritative on the | |
edce4d98 | 42 | * reply status. EBITTEST (E_ABORT) is no longer a valid test outside |
43 | * of client_side_reply.c. | |
44 | * Problem the second: resources are wasted if we delay in cleaning up. | |
45 | * Problem the third we can't depend on a connection close to clean up. | |
9e008dda | 46 | * |
63be0a78 | 47 | \par Nice thing the first: |
9e008dda | 48 | * Any step in the stream can callback with data |
edce4d98 | 49 | * representing an error. |
50 | * Nice thing the second: once you stop requesting reads from upstream, | |
51 | * upstream can be stopped too. | |
52 | * | |
63be0a78 | 53 | \par Solution #1: |
54 | * Error has a callback mechanism to hand over a membuf | |
9e008dda | 55 | * with the error content. The failing node pushes that back as the |
edce4d98 | 56 | * reply. Can this be generalised to reduce duplicate efforts? |
57 | * A: Possibly. For now, only one location uses this. | |
58 | * How to deal with pre-stream errors? | |
59 | * Tell client_side_reply that we *want* an error page before any | |
60 | * stream calls occur. Then we simply read as normal. | |
63be0a78 | 61 | * |
62 | * | |
d85b8894 | 63 | \section pconn_logic Persistent connection logic: |
63be0a78 | 64 | * |
65 | \par | |
66 | * requests (httpClientRequest structs) get added to the connection | |
67 | * list, with the current one being chr | |
9e008dda | 68 | * |
63be0a78 | 69 | \par |
70 | * The request is *immediately* kicked off, and data flows through | |
71 | * to clientSocketRecipient. | |
9e008dda | 72 | * |
63be0a78 | 73 | \par |
74 | * If the data that arrives at clientSocketRecipient is not for the current | |
75 | * request, clientSocketRecipient simply returns, without requesting more | |
76 | * data, or sending it. | |
77 | * | |
78 | \par | |
9e008dda AJ |
79 | * ClientKeepAliveNextRequest will then detect the presence of data in |
80 | * the next ClientHttpRequest, and will send it, restablishing the | |
63be0a78 | 81 | * data flow. |
