Can't happen, either fbased (this fname != NULL), or fname is set to
"none" above.

Removing the fname null check was intentional?

Could you (or Steffen, or Lucas) try the attached patch? It's based on
2.4.x, but should work for trunk too..


I currently do not have a quick way to do builds on Windows, but if 
Steffen could provide a build including your patch I could easily redo 
the described test.

Re: mod_proxy_balancer doesn't work with 2.4.32

[Eric Covener]

IIRC they use a combo of AP_PARENT_PID and postconfig userdata to tell
between parent/child an first/second pass.

But i also vaguely recall there is a helper for it now?

Is there a way for a module to know whether it's run by the parent or

The slotmem does not try to attach() first anymore, this needs to be restored...

Wait:
 [pid 19136:tid 136] mod_proxy_balancer.c(917): AH01178: Doing
balancers create: 552, 1 (6)
 [pid 19136:tid 136] mod_proxy_balancer.c(986): AH01184: Doing workers
create: balancer://mycluster (p111c5be7_mycluster), 984, 2 [0]
 [pid 30160:tid 756] mod_proxy_balancer.c(917): AH01178: Doing
balancers create: 552, 1 (6)
 [pid 30160:tid 756] (17)File exists: AH01179: balancer slotmem_create failed

Two processes (PIDs) creating the same balancer, two httpd instances
with the same configuration?
(IIRC, Windows MPM is threaded only, no "forking" right?).

Hmm no, mod_proxy_balancer is asking for slotmem_shm explicitely, so
it can't be _plain.

I really wonder why mod_slotmem_shm::slotmem_create() fails w/o its
own error message (AH02611)...
LogLevel debug maybe Steffen?

Besides, isn't this specifically tested in the Perl test framework?

It does not look like mod_slotmem_shm is used (missing some error
logging from there), mod_slotmem_plain maybe?

Also, more context would be appreciated, full/relevant VirtualHost
config (including IP:port, ServerName/ServerAlias eventually
"anonymized"), BalancerPersist on/off(?) and whether or not other
balancers are configured elsewhere (i.e. full httpd.conf if
possible...).

Can Windows users reproduce this very basic case here with
mod_slotmem_shm (it doesn't seem Windows specific to me)?

Yann.

Can anyone reproduce outside of Windows?

No doubt something in Yann's slotmem changes that affect Windows.
