62e76326 | 36 | /* Errors and client side |
edce4d98 | 37 | * |
38 | * Problem the first: the store entry is no longer authoritative on the | |
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. | |
43 | * | |
44 | * Nice thing the first: Any step in the stream can callback with data | |
45 | * representing an error. | |
46 | * Nice thing the second: once you stop requesting reads from upstream, | |
47 | * upstream can be stopped too. | |
48 | * | |
49 | * Solution #1: Error has a callback mechanism to hand over a membuf | |
50 | * with the error content. The failing node pushes that back as the | |
51 | * reply. Can this be generalised to reduce duplicate efforts? | |
52 | * A: Possibly. For now, only one location uses this. | |
53 | * How to deal with pre-stream errors? | |
54 | * Tell client_side_reply that we *want* an error page before any | |
55 | * stream calls occur. Then we simply read as normal. | |
