[Tarantool-patches] [PATCH luajit] test: skip lj-1470 test on RED OS

[Tarantool-patches] [PATCH luajit] test: skip lj-1470 test on RED OS

[Sergey Kaplun via Tarantool-patches]

RED OS for some reason sets `errno` to 2 ENOENT ("No such file or
directory") after the call to `mktime()`. So just skip the test for it.
---

Branch: https://github.com/tarantool/luajit/tree/skaplun/fix-os-time-test-redos
Failed workflow: https://github.com/tarantool/tarantool/actions/runs/28585213455/job/84775371860?pr=12886#step:5:20692

Side note: The errno is set for __any__ call to the `mktime()`.

Tested inside the following Docker:

===================================================================
FROM registry.red-soft.ru/ubi8/ubi-minimal:latest

RUN dnf update -y && \
    dnf install -y cmake vim make git curl gcc g++ gdb man && \
    dnf clean all
===================================================================

| docker build . --tag redos
| docker run --network=host -ti redos bash

Then clone LuaJIT and proceed as usual.

With the patch the test skipped:

Why do you think the problem is in RedOS, not in Glibc?

I propose skipping test for some Glibc version using CMake macro

introduced in the following commit:

commit af0f59da76292f30ff75be1ab01458d47b226995
Author: Sergey Kaplun <skaplun@tarantool.org>
Date:   Wed Dec 4 15:03:56 2024 +0300

     test: fix LuaJIT-tests for old libc version

Otherwise, we will skip this test for always for RedOS.

in RedOS 8 glibc version is 2.36-14:

[root@pony /]# rpm -qa | grep glibc
glibc-common-2.36-14.red80.x86_64
glibc-gconv-extra-2.36-14.red80.x86_64
glibc-langpack-en-2.36-14.red80.x86_64
glibc-langpack-ru-2.36-14.red80.x86_64
glibc-2.36-14.red80.x86_64
glibc-devel-2.36-14.red80.x86_64



Also, why detect_redos() is not in utils.lua?

Sergey,

seems it is not an OS-specific issue.

strace reports that glibc is looking for /etc/localtime, but the file 
does not exist:

strace ./src/luajit -e "print(os.time(os.date('*t', -1)))"

<snipped>

futex(0x70d8ab961070, FUTEX_WAKE_PRIVATE, 2147483647) = 0
rt_sigaction(SIGINT, {sa_handler=0x4057e5, sa_mask=[INT], 
sa_flags=SA_RESTORER|SA_RESTART, sa_restorer=0x70d8ab79bfd0}, 
{sa_handler=SIG_DFL, sa_mask=[], sa_flags=0}, 8) = 0
openat(AT_FDCWD, "/etc/localtime", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No 
such file or directory)
openat(AT_FDCWD, "/etc/localtime", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No 
such file or directory)
newfstatat(1, "", {st_mode=S_IFCHR|0620, st_rdev=makedev(0x88, 0), ...}, 
AT_EMPTY_PATH) = 0
write(1, "nil\n", 4nil
)                    = 4
rt_sigaction(SIGINT, {sa_handler=SIG_DFL, sa_mask=[INT], 
sa_flags=SA_RESTORER|SA_RESTART, sa_restorer=0x70d8ab79bfd0}, 
{sa_handler=0x4057e5, sa_mask=[INT], sa_flags=SA_RESTORER|SA_RESTART, 
sa_restorer=0x70d8ab79bfd0}, 8) = 0
munmap(0x414e2000, 131072)              = 0
exit_group(0)                           = ?
+++ exited with 0 +++


The same issue can be reproduced on other Linux distros after removing 
/etc/localtime.

On redOS the issue can be fixed by creating a symlink:

ln -sf /usr/share/zoneinfo/Europe/Moscow /etc/localtime

<snipped>

ctest -V -R lj-1470-os-time-epoch-minus-1s.test.lua

<snipped>

The following tests passed:
test/tarantool-tests/lj-1470-os-time-epoch-minus-1s.test.lua

100% tests passed, 0 tests failed out of 1

Label Time Summary:
tarantool-tests    =   0.00 sec*proc (1 test)

Total Test time (real) =   0.01 sec


I propose checking a file /etc/localtime instead checking an OS name, 
this will be a more correct fix.

However, LGTM, I will not insist.

Indeed, this looks like much more bulletproof solution. Thanks for the
feedback! I've fixed this in v2 series [1].
