Description Attila 2018-06-14 07:57:47 UTC 
Description of problem:

Since Fedora 27 the mpm_event_module is activated by default.
Outputs written by cgi-scripts to "stderr" during https-sessions are unusable and ending up in the file error_log instead of ssl_error_log. The entries made by cgi-scripts in the file error_log don't have any timestamp, User-Agent, referer et cetera. The LogFormat from httpd.conf is ignored. All I can see is the native output from the cgi-script.

Version-Release number of selected component (if applicable):

httpd-2.4.33-2

How reproducible:

Create a cgi-script which can output the word "Test" to stderr.

Steps to Reproduce:
1. Start httpd: systemctl start httpd.service
2. Send a https-request to a cgi-script which can produce an output (like the word "Test") to stderr.
3. Check the file /var/log/httpd/error_log

Actual results:

The file /var/log/httpd/error_log contains a line with the word "Test". No date, timestamp, et cetera. This is wrong and should be written to /var/log/httpd/ssl_error_log, because of ssl-request.

Expected results:

The file /var/log/httpd/ssl_error_log should contain a line with the word "Test" like this:

Wed Jun 13 16:44:20.295009 2018] [cgi:error] [pid 14844] [client ::1:59776] AH01215: Test: /var/www/cgi-bin-ssl/test.cgi

Additional info:

A possible workaround is to switch back to prefork MPM in the file /etc/httpd/conf.modules.d/00-mpm.conf

LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
#LoadModule mpm_event_module modules/mod_mpm_event.so
Comment 1 Joe Orton 2018-09-26 11:47:33 UTC 
Known issue upstream, no fix available at the moment, sorry.
Comment 2 Ben Cotton 2018-11-27 14:21:40 UTC 
This message is a reminder that Fedora 27 is nearing its end of life.
On 2018-Nov-30  Fedora will stop maintaining and issuing updates for
Fedora 27. It is Fedora's policy to close all bug reports from releases
that are no longer maintained. At that time this bug will be closed as
EOL if it remains open with a Fedora  'version' of '27'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 27 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
