Kiran Kumar M R commented on HADOOP-11638:
------------------------------------------
I have added new patch-004 to include Mac OS specific code.
Mac has {{int pthread_threadid_np(pthread_t thread, uint64_t *thread_id)}}
method to get thread id
- Its declared in {{pthread.h}} Refer
https://opensource.apple.com/source/libpthread/libpthread-105.1.4/pthread/pthread.h
- Its implementation can be seen at
https://opensource.apple.com/source/libpthread/libpthread-105.1.4/src/pthread.c
- Its usage can be seen at
https://opensource.apple.com/source/libpthread/libpthread-105.1.4/src/pthread_rwlock.c
as below
{code}
uint64_t myid;
(void)pthread_threadid_np(pthread_self(), &myid);
{code}
Now my patch code is:
{code}
static unsigned long pthreads_thread_id(void)
{
unsigned long thread_id = 0;
#if defined(__linux__)
thread_id = (unsigned long)syscall(SYS_gettid);
#elif defined(__FreeBSD__)
thread_id = (unsigned long)pthread_getthreadid_np();
#elif defined(__sun)
thread_id = (unsigned long)pthread_self();
#elif defined(__APPLE__ )
(void)pthread_threadid_np(pthread_self(), &thread_id);
#else
#error "Platform not supported"
#endif
return thread_id;
}
{code}
[~cnauroth], please check if patch-004 works on Mac
> OpensslSecureRandom.c pthreads_thread_id should support FreeBSD and Solaris
> in addition to Linux

> Project: Hadoop Common
> Issue Type: Bug
> Components: native
> Affects Versions: 2.6.0
> Reporter: Dmitry Sivachenko
> Assignee: Kiran Kumar M R
> Labels: freebsd
> Attachments: HADOOP-11638-001.patch, HADOOP-11638-002.patch,
> HADOOP-11638-003.patch, HADOOP-11638-004.patch
>
>
> In OpensslSecureRandom.c you use Linux-specific syscall gettid():
> static unsigned long pthreads_thread_id(void)
> {
> return (unsigned long)syscall(SYS_gettid);
> }
> Man page says:
> gettid() is Linux-specific and should not be used in programs that are
> intended to be portable.
> This breaks hadoop-2.6.0 compilation on FreeBSD (may be on other OSes too).
