The generated makefile contains:
CC=cc
CFLAGS1= -DAIX=43 -DUSE_PTHREAD_SERIALIZED_ACCEPT -U__STR__ -DAIX_BIND_PROCE
SSOR -qnogenpcomp -qnousepcomp -DMOD_SSL=208101 -DUSE_HSREGEX -DEAPI -DUSE_E
XPAT -I$(SRCDIR)/lib/expat-lite
cc defaults to clx (IBM C Compiler). To have semaphores support on mod_ssl,
some of this combinations is required:
USE_SYSVSEM_SERIALIZED_ACCEPT (mod_ssl.h line 289)
Or
defined(__FreeBSD__) && defined(__FreeBSD_version) && __FreeBSD_version >=
300000
Or
defined(LINUX) && defined(__GLIBC__) && defined(__GLIBC_MINOR__) && LINUX
>= 2 && __GLIBC__ >= 2 && __GLIBC_MINOR__ >= 1
Or
defined(SOLARIS2)
Or
defined(__hpux)
For AIX (if you see ap_config.h) you get
#if !defined(USE_PTHREAD_SERIALIZED_ACCEPT) (line 282 ap_config.h)
#define USE_FCNTL_SERIALIZED_ACCEPT
#endif
If you take a look at configure in /src directory you have (for AIX 4.3):
CFLAGS="$CFLAGS -DAIX=43 -DUSE_PTHREAD_SERIALIZED_ACCEPT -U__STR__" (line
324 of /src/configure)
so USE_PTHREAD_SERIALIZED_ACCEPT gets only defined for AIX 4.3,
Resuming, for AIX 4.3 USE_PTHREAD_SERIALIZED_ACCEPT is defined and
USE_FCNTL_SERIALIZED_ACCEPT for other
versions.
Anyway, the only way for mod_ssl under an AIX system to include semaphores
support would be that USE_SYSVSEM_SERIALIZED_ACCEPT
were defined somewhere, but I can't see how can this happen.
I ran OpensSSL, mod_ssl and Apache configuration and compile carefully, and
everything went fine.
If you look carefully, my system is behaving as it should (unless I'm
missing something) -> no semaphores support for mod_ssl.
Anyway.. if you do "SSLMutex sem" in httpd conf, you get "SSLMutex:
Semaphores not available on this platform".
Can you do "SSLMutex sem" with no prob??? If you do.. I cant figure how,
from the 'code' point of view.
I really must be screwing something.
I know semaphores are available under AIX, but what I didn't catch is "Are
they available for mod_ssl?"
I'm really lost here. Any enlightment is really really appreciated.
Thanks for your response.
Diego
