The proper logic to add to a cache is
wrlock
test if exists again
add element

because there is a race condition in the logic below
rdlock
test if the element exists

Hi,
I am not sure about what i will say, but i think all these mutex are broken.
when i did that, i think i used apr_thread_mutex_create which use a pool
(st->pool) which is the server pool.
This function is to use in a child, not between all forked child.
When it create the mutex, it do a apr_pc
I could be completely confused here, but isn't this (a shared
cache) already something we have a framework for in mod_ssl?
Not that what's *in* mod_ssl (well, the *scache* files)
is the solution for ldap, but the particulars design and
logic flow certainly should work, right?
mod_ssl mutex are totally different. global mutex are used.
Actually, the mutex is in the module_conf, so i think when apache fork
childs, this mutex is no more valid, and each child will have a value
for it.
There is also in util_ldap.c, apr_thread_mutex_create(&st->mutex,
APR_THREAD_MUTEX_DEFA

Modified:support rotatelogs.c
Log:
add "-l" option to indicate interval is based on localtime not gmt
a CHANGES entry would be good
also, I guess this is exactly the feature requested/implemented in PR 24417?
