From 5d3a7cefa27f3fe20a9c6991fb044815b38aac01 Mon Sep 17 00:00:00 2001 From: eunhhu Date: Sun, 27 Sep 2026 08:09:40 +0100 Subject: Deliver an app's saved sends over HTTP, in order and in batches (083) pure-serve --send OUTPUT=http://host:port/path wires an output: after every save the owner queues the new sends as JSON (fields and groups) and a thread per output posts them in order with X-Pure-Source, X-Pure-Sequence and Idempotency-Key. A 2xx, or a Pure receiver's refusal, delivers; the owner then trims. 408, 429, 5xx and no answer are sent again after a pause growing to 10 s, other answers every 10 s: nothing is dropped. A Pure receiver applies a delivered message with pure_app_deliver (now taking placed fields) and advertises X-Pure-Batch: 256; the sender then posts up to that many numbers in a row as one JSON array (X-Pure-Count), applied in order in one burst with one save. Delivery kept up with orders once batched (391 deliveries/s one at a time; a backlog of 20,000 went at 60k/s). With four clients ordering, killing the receiver and then the sender (-9) left the receiver's count and total equal to what the sender saved, five times and under ASan. --- prototypes/connections/module.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'prototypes/connections/module.h') diff --git a/prototypes/connections/module.h b/prototypes/connections/module.h index ed40c15..3441c03 100644 --- a/prototypes/connections/module.h +++ b/prototypes/connections/module.h @@ -316,8 +316,9 @@ void pure_app_trim(PureApp *, uint32_t output, uint64_t through); * before is not applied again: it succeeds with app->duplicate set.
