New submission from Garrett Cooper <yaneg...@gmail.com>:
os.chflags isn't `available' even though chflags support is available on the
system:
>>> filter(lambda x: x.startswith('chflags'), dir(os))
[]
>>> platform.uname()
('FreeBSD', 'bayonetta.local', '9.0-CURRENT', 'FreeBSD 9.0-CURRENT #0 r206173M:
Mon Apr 26 22:45:06 PDT 2010
r...@bayonetta.local:/usr/obj/usr/src/sys/BAYONETTA.ata', 'amd64', 'amd64')
>>> filter(lambda x: x.startswith('chflags'), dir(os))
[]
>>> sys.version
'2.6.5 (r265:79063, May 16 2010, 23:37:42) \n[GCC 4.2.1 20070719 [FreeBSD]]'
I'm looking into why this is not properly detected via configure (here's the
snippet though):
configure:17257: checking for chflags
configure:17288: cc -o conftest -O2 -pipe -fno-strict-aliasing -pipe -O2
-march=nocona -D__wchar_t=wchar_t -DTHREAD_STACK_SIZE=0x100000 -pthread

Compiling the standalone test works:
$ cat ~/test_chflags.c
#include <sys/stat.h>
#include <unistd.h>
int main(int argc, char*argv[])
{
if(chflags(argv[0], 0) != 0)
return 1;
return 0;
}
$ gcc -o ~/test_chflags ~/test_chflags.c
$ echo $?
0
Also, another sidenote: nowhere is *chflags(2) considered a POSIX feature (I
doublechecked opengroup.org and Google). It is strictly a _Unix_ feature. I say
this because the POSIX functionality tester explicitly looks for this `POSIX'
compatible feature.
