From 069bcf619b5ce62f79f249a43432fa2de2281d1d Mon Sep 17 00:00:00 2001 From: Kim Alvefur Date: Sun, 24 Sep 2023 13:41:54 +0200 Subject: mod_storage_internal: Fix fast trimming of archive with exactly one item This method would previously never delete the first (and only) item since it works out which item should become the first item after the trim operation, which doesn't make sense when all should be removed. This also works as an optimization for when all the last item should be trimmed, thus items should be removed. --- plugins/mod_storage_internal.lua | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'plugins/mod_storage_internal.lua') diff --git a/plugins/mod_storage_internal.lua b/plugins/mod_storage_internal.lua index 66200977..bde294b2 100644 --- a/plugins/mod_storage_internal.lua +++ b/plugins/mod_storage_internal.lua @@ -347,6 +347,13 @@ end function archive:trim(username, to_when) local list, err = datamanager.list_open(username, host, self.store); if not list then return list,err;end + + -- shortcut: check if the last item should be trimmed, if so, drop the whole archive + local last = list[#list].when or datetime.parse(list[#list].attr.stamp); + if last <= to_when then + return datamanager.list_store(username, host, self.store, nil); + end + -- luacheck: ignore 211/exact local i, exact = binary_search(list, function(item) local when = item.when or datetime.parse(item.attr.stamp); -- cgit v1.2.3
