>Description:
Htpasswd, htdigest and mod_auth_digest use tmpnam(NULL), which won't
work in HP-UX 11 if -lpthread is in link.
I got the following from HP's tech support:
"This is covered by the man page for tpmnam().
$ man tmpnam
....
tmpnam() Always generates a file name using the path-prefix
.....
in that array and returns s. For multi-thread
applications, if s is a NULL pointer, the
operation is not performed and a NULL pointer is
returned.
ie for multi-threaded applications you need to supply the address of
the buffer tmpnam should use."
>How-To-Repeat:
I built apache with:
CC=cc CFLAGS="-g +e" \
./configure --prefix=/usr/local/apache_1.3.9 \
--enable-module=rewrite
make
Now try to run htpasswd in src/support:
$ ./htpasswd -c test test
New password: ....
Re-type new password: ....
./htpasswd: unable to create temporary file
fopen: No such file or directory
>Fix:
Either remove -lpthread from LIBS in src/Configure (that's what I did
as I couldn't figure out any reason to use -lpthread in link phase)
or if it is needed to link with -lpthread provide a pointer
(to array of at leas L_tmpnam bytes) to tmpnam call.
