Description pservit 2010-02-01 06:07:05 UTC 
FreeBSD 7.2-RELEASE-p4 amd64

Latest version of mod_fcgid 2.3.5 fails with this error in httpd-error.log:

[Mon Feb 01 15:55:03 2010] [emerg] (13)Permission denied: mod_fcgid: apr_global_mutex_child_init error

Previous version 2.3.4 works fine.



As I can see, it tries to create mutex in /var/tmp
On FreeBSD this dir has theese permissions:
drwxrwxrwt   6 root    wheel      3.0K Feb  1 15:55 tmp

Version 2.3.4 creates file with "www" owner:
-rw-------  1 www  wheel     0B Feb  1 15:55 tmp.2.CMfelr

But version 2.3.5 creates it with "root" owner:
-rw-------  1 root  wheel     0B Feb  1 16:02 tmp.4.GgLDa9

Thank you. It works.

I just change this line in patch to compile:
#define AP_NEED_SET_MUTEX_PERMS 1

Will you release new version of mod_fcgid soon ?
I want send PR to update freebsd port to latest version.

I'm thinking about rolling 2.3.6 at the end of this week, for potential release sometime next week; that will give us a little more time to get feedback from early adopters without delaying the regression fix too much.

Unfortunately it is always hard to predict when a release will be finalized.  If I were you I'd patch it for now.
