From 0c47bc2bc2497771740410bcd965d4d4fd0e3524 Mon Sep 17 00:00:00 2001 From: eunhhu Date: Sat, 26 Sep 2026 07:47:57 +0100 Subject: Let a burst hold up to 256 documents A burst ended once 16 keys had joined it, so 64 writers needed four commits a round and some waited through several (p50 17.4 ms). The pending documents now grow on demand up to 256 keys, which also makes PureApp 1.3 KB smaller (3,128 bytes). With 64 connections a commit now carries 26 events on average instead of 12 and the median PUT waits 9.2 ms; throughput moves less, since each commit writes more and the SD card's syncs take most of the time. --- prototypes/connections/module.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'prototypes/connections/module.c') diff --git a/prototypes/connections/module.c b/prototypes/connections/module.c index f8ebdd3..ebb746f 100644 --- a/prototypes/connections/module.c +++ b/prototypes/connections/module.c @@ -1038,6 +1038,7 @@ void pure_app_stop(PureApp *app) { pure_draft_close(app->list_drafts[i]); } pure_draft_close(app->stored_values); + free(app->pending); pure_undo_free(&app->undo); free(app->arena.bytes); free(app->view_arena.bytes); @@ -1164,6 +1165,13 @@ PureResult pure_app_message(PureApp *app, uint32_t input, const char *key, int64 PureResult saved = pure_app_save(app); if (saved != PURE_OK) return saved; } + if (app->pending_count == app->pending_capacity) { + unsigned capacity = app->pending_capacity ? 2 * app->pending_capacity : 16; + struct PurePending *grown = realloc(app->pending, capacity * sizeof(*grown)); + if (!grown) return PURE_ALLOCATION; + app->pending = grown; + app->pending_capacity = capacity; + } PureResult opened = app->data.open(app->data.context, 0, key, &app->document, &app->revision); if (opened != PURE_OK) { app->document = NULL; return opened; } if (base >= 0 && base != app->revision) { pure_app_finish(app); return PURE_CONFLICT; } -- cgit v1.2.3
