Bug 120409

Summary: www/apache20 (7.0-RC1) segfault on HUP w/ some php5 extensions
Product: Ports & Packages Reporter: Andy Hilker <ah>
Component: Individual Port(s)Assignee: freebsd-apache (Nobody) <apache>
Status: Closed FIXED    
Severity: Affects Only Me    
Priority: Normal    
Version: Latest   
Hardware: Any   
OS: Any   

Description Andy Hilker 2008-02-08 14:10:01 UTC 
Consider the following setup:
- 7.0-RC1
- apache-2.0.63
- php5-5.2.5_1 with extensions: openssl or ftp or mhash

Then hupping the apache will not longer work:
kill -1 `cat /var/run/httpd.pid`

-- httpd-error.log --
[notice] SIGHUP received.  Attempting to restart
[notice] seg fault or similar nasty error detected in the parent process
-- httpd-error.log --


More information:
- On 6.2 machines, i can not repeat this error.

- Not having any of those 3 modules (openssl, ftp, mhash) will avoid the problem (other php5 modules i am using work fine)

How-To-Repeat: It is enough if you have 
- 7.0-RC1 (amd64)
- apache-2.0.63
- php5-5.2.5_1 with at least on of (openssl, ftp, mhash) extension

kill -1 `cat /var/run/httpd.pid`

I have to correct myself: FreeBSD 6.2 is also affected.
Comment 3 Andy Hilker 2008-02-25 12:57:31 UTC 
... and it happens on i386 (not only amd64) with latest port (which
contains the latest Makefile version with "Workaround a sh segfault
on 6-STABLE").

Thanks for your answer.

The problem on 6.2/i386 seems to be related to
        http://www.freebsd.org/cgi/query-pr.cgi?pr=115893

If I use the patch
(http://www.freebsd.org/cgi/query-pr.cgi?prp=115893-1-diff&n=/patch-1.diff)
I get the segmentation fault on HUP. If I use the workaround for
php5-ffmpeg (remove --enable-pthreads from multimedia/ffmpeg/Makefile)
everything works.


The problem on 7.0/amd64 occured after upgrading php5+apache (nothing
else was changed), but ok, i have solved it by changing to apache22.
I can not test anymore if changing the order in extensions.ini would
have any effect.

I think you can close ports/120409 and I will update the PR 115893.

regards,
andy
