ws2_32 is the new version of the library that should be used, as it contains the require functionality from wsock32 as well as some more (which is why some binaries were already using ws2_32). Michael Paquier, reviewed by MauMau

Threading
|
|
=========
|
|
|
|
This program is run by configure to determine if threading is
|
|
properly supported on the platform.
|
|
|
|
You can run the program manually to see details, which shows if your
|
|
native libc functions are thread-safe, or if we use *_r functions or
|
|
thread locking.
|
|
|
|
To use this program manually, you must:
|
|
|
|
o run "configure"
|
|
o compile the main source tree
|
|
o compile and run this program
|
|
|
|
If your platform requires special thread flags that are not tested by
|
|
/config/acx_pthread.m4, add PTHREAD_CFLAGS and PTHREAD_LIBS defines to
|
|
your template/${port} file.
|

Windows Systems
|
|
===============
|
|
|
|
Windows systems do not vary in their thread-safeness in the same way that
|
|
other systems might, nor do they generally have pthreads installed, hence
|
|
on Windows this test is skipped by the configure program (pthreads is
|
|
required by the test program, but not PostgreSQL itself). If you do wish
|
|
to test your system however, you can do so as follows:
|
|
|
|
1) Install pthreads in you Mingw/Msys environment. You can download pthreads
|
|
from ftp://sources.redhat.com/pub/pthreads-win32/.
|
|
|
|
2) Build the test program:
|
|
|
|
gcc -o thread_test.exe \
|
|
-D_REENTRANT \
|
|
-D_THREAD_SAFE \
|
|
-D_POSIX_PTHREAD_SEMANTICS \
|
|
-I../../../src/include/port/win32 \
|
|
thread_test.c \
|
|
-lws2_32 \
|
|
-lpthreadgc2
|
|
|
|
3) Run thread_test.exe. You should see output like:
|
|
|
|
dpage@PC30:/cvs/pgsql/src/tools/thread$ ./thread_test
|
|
Your GetLastError() is thread-safe.
|
|
Your system uses strerror() which is thread-safe.
|
|
getpwuid_r()/getpwuid() are not applicable to Win32 platforms.
|
|
Your system uses gethostbyname which is thread-safe.
|
|
|
|
Your platform is thread-safe.
