Sylwester Lachiewicz created THRIFT-6385:
--------------------------------------------
Summary: TNonblockingServerTest
allocation_failure_on_the_io_thread_does_not_end_the_process always fails on
macOS
Key: THRIFT-6385
URL: https://issues.apache.org/jira/browse/THRIFT-6385
Project: Thrift
Issue Type: Bug
Components: C++ - Library
Affects Versions: 0.25.0
Reporter: Sylwester Lachiewicz
Fix For: 0.26.0
The case forks and caps the child's address space with {{setrlimit(RLIMIT_AS,
...)}}, and the child exits with 2 when that call fails. macOS does not accept
an RLIMIT_AS limit and returns EINVAL, so the child always exits 2 and the case
fails:
{noformat}
TNonblockingServerTest.cpp:507: error: in
"TNonblockingServerTest/allocation_failure_on_the_io_thread_does_not_end_the_process":
check (((*(int *)&(status)) >> 8) & 0x000000ff) == 0 has failed [2 != 0]
{noformat}
Reproduced three times out of three with the autotools build of master on macOS
27 (Apple clang 21, libevent 2.1.13); a standalone {{setrlimit(RLIMIT_AS,
...)}} returns EINVAL there as well. The case is guarded by {{#ifndef _WIN32}}
only, while another case in
[lib/cpp/test/TNonblockingServerTest.cpp|https://github.com/apache/thrift/blob/master/lib/cpp/test/TNonblockingServerTest.cpp]
is limited to {{__linux__}}. It came in with
[0b9e7d808|https://github.com/apache/thrift/commit/0b9e7d808]. It is not the
intermittent Windows failure of THRIFT-6244.
The case could report itself as skipped when the limit cannot be set, or be
limited to platforms that support RLIMIT_AS.
