From 9fdb586592e24fbd42a42b1ea8a06fcb4a6dbf93 Mon Sep 17 00:00:00 2001 From: bfredl Date: Wed, 18 Jan 2023 11:54:49 +0100 Subject: [PATCH 1/3] fix(unittests): do not consider process crash to be a success unittests relied on the exact setup of coredumps on CI to detect process crashing, and otherwise completely discarded errors. Dectect child process failure reliably using process status, so that unittests actually work locally as well. --- test/unit/helpers.lua | 27 +++++++++++++++++++-------- 1 file changed, 19 insertions(+), 8 deletions(-) diff --git a/test/unit/helpers.lua b/test/unit/helpers.lua index 29ea0235be..4576edf436 100644 --- a/test/unit/helpers.lua +++ b/test/unit/helpers.lua @@ -471,8 +471,9 @@ else close = ffi.C.close, wait = function(pid) ffi.errno(0) + local stat_loc = ffi.new('int[1]', {0}) while true do - local r = ffi.C.waitpid(pid, nil, ffi.C.kPOSIXWaitWUNTRACED) + local r = ffi.C.waitpid(pid, stat_loc, ffi.C.kPOSIXWaitWUNTRACED) if r == -1 then local err = ffi.errno(0) if err == ffi.C.kPOSIXErrnoECHILD then @@ -485,6 +486,7 @@ else assert(r == pid) end end + return stat_loc[0] end, exit = ffi.C._exit, } @@ -730,18 +732,22 @@ local function check_child_err(rd) end end -local function itp_parent(rd, pid, allow_failure) - local err, emsg = pcall(check_child_err, rd) - sc.wait(pid) +local function itp_parent(rd, pid, allow_failure, location) + local ok, emsg = pcall(check_child_err, rd) + local status = sc.wait(pid) sc.close(rd) - if not err then + if not ok then if allow_failure then - io.stderr:write('Errorred out:\n' .. tostring(emsg) ..
