Hi all,
I'm adding a merge function (for use with directory-based configuration
and server-based configuration).
When I finished the function, I noticed that it was causing whitescreens
(empty responses).
"White screens" in my experience are often caused by the apache process
segfaulting (though you didn't mention what platform you are on; this is
unix-ish). Have you checked your apache error log to see if this is the
case? You also may want to change your LogLevel to "debug" to get the
most information possible into those logs.
As you can see below, I allocate memory via 'apr_pcalloc' and then I:
(1) loop through each existing 'rbl_handler' from the parentdir_cfg,
copying
it to the new_dir_cfg, then
(2) loop through each existing 'rbl_handler' from the subdir_cfg,
copying it
to the new_dir_cfg.
A VERY brief look at your code looks like you're moving pointers; you
may want to consider using apr_pstrdup and/or memcpy instead, unless you
are SURE the pointers in question are pointing at things which are in a
long-life pool.
HTH,
Todd
