File 2837-Reset-inet_db-timer-even-if-file-is-up-to-date.patch of Package erlang
From 452703a85afd397b3850e741c09d237ace44dd7c Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jos=C3=A9=20Valim?= <jose.valim@dashbit.co> Date: Tue, 3 Nov 2020 13:32:32 +0100 Subject: [PATCH] Reset inet_db timer even if file is up to date Prior to this patch, if 5 seconds passed and the resolv_conf or hosts_file were up to date, we would continue to check for the file update on every inet_res or inet_hosts operation. This PR makes sure that the timer is updated even if the file is up to date, so we check again only in the next 5 seconds. --- lib/kernel/src/inet_db.erl | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/lib/kernel/src/inet_db.erl b/lib/kernel/src/inet_db.erl index 814c3f4276..e42856dd08 100644 --- a/lib/kernel/src/inet_db.erl +++ b/lib/kernel/src/inet_db.erl @@ -1214,6 +1214,8 @@ handle_set_file(ParseFun, File, Bin, From, State) -> handle_update_file( Finfo, File, TagTm, TagInfo, ParseFun, From, #state{db = Db} = State) -> + ets:insert(Db, {TagTm, times()}), + %% %% Update file content if file has been updated %% @@ -1224,7 +1226,6 @@ handle_update_file( {ok, Finfo_1} -> %% File updated - read content ets:insert(Db, {TagInfo, Finfo_1}), - ets:insert(Db, {TagTm, times()}), Bin = case erl_prim_loader:get_file(File) of {ok, B, _} -> B; @@ -1234,7 +1235,6 @@ handle_update_file( _ -> %% No file - clear content and reset monitor ets:insert(Db, {TagInfo, undefined}), - ets:insert(Db, {TagTm, times()}), handle_set_file(ParseFun, File, <<>>, From, State) end. -- 2.26.2
