[Bug 59374] New: "AH00169 ... shutting down" : not caught using ErrorLog program

https://bz.apache.org/bugzilla/show_bug.cgi?id=59374

            Bug ID: 59374
           Summary: "AH00169 ... shutting down" : not caught using
                    ErrorLog program
           Product: Apache httpd-2
           Version: 2.4-HEAD
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
          Assignee: bugs@httpd.apache.org
          Reporter: ben.rubson@gmail.com

Hello,

Using the following configuration :

ErrorLog "| /usr/bin/logger -t httpd"
LogLevel notice

The following shutting down message never appears into the logs :
Apr 25 16:38:00 srv httpd[98967]: [mpm_prefork:notice] [pid 98967] AH00169:
caught SIGTERM, shutting down

If we use a ErrorLog file, or ErrorLog syslog, this message correctly appears
into the log.

Is ErrorLog program killed before the last log messages ?

Thank you,

Best regards,

Ben

Thank you for your report. As part of an effort to clean up our issue tracker,
we are closing tickets that have seen no activity for more than 5 years. If
this issue is still relevant to a current version of Apache httpd (2.4.x or
trunk), please reopen this ticket or open a new one with updated information.
We appreciate your contribution to the project.

In 2.4, piped loggers see a sigterm early during shutdown compared to 2.2.

To get the 2.2 behavior, where /bin/sh usually ate the sigterm, use |$ as the
first two characters instead of just |

There is currently a design problem around the stopping/restarting of piped
loggers that currently errs on the side of losing some messages at shutdown.

Eric,

Thank you for your answer.

I then tested the following with Apache 2.4 :
ErrorLog "|$ /usr/bin/logger -t httpd"
But it did not help.

I also tested, with no luck :
ErrorLog "| /bin/sh -c \'/usr/bin/logger -t httpd\'"
ErrorLog "|$ /bin/sh -c \'/usr/bin/logger -t httpd\'"

Strangely with these 2 tests (as well as with the first one), /bin/sh does not
appear in my processes list.

Note that with Apache 2.2 I get the same behavior, last messages are lost.

Would it be hard to solve this design problem around the stopping of piped
loggers ?

Many thanks,

Ben
