Bug ID: 63283
Summary: -DFOREGROUND not usable due to SIGWINCH
Product: Apache httpd-2
Version: 2.4-HEAD
Hardware: PC
OS: Mac OS X 10.1
Status: NEW
Severity: normal
Priority: P2
Component: Core
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Hello,
I wanted to run Apache with -DFOREGROUND so that I
* can conveniently/efficiently develop and test Apache config files
* can watch logs in stdout/stderr
* can kill the process with CtRL+C
* can restart the process with whatever args I want
However, whenever I resize my console, I get
[Mon Mar 25 08:01:49.545232 2019] [mpm_prefork:notice] [pid 494] AH00170:
caught SIGWINCH, shutting down gracefully
Terminated
Is there any way to use -DFOREGROUND in combination with an interactive
terminal?
I understand that SIGWINCH is internally used to initiate a graceful shutdown
and I don't want to question this design decision. Changing the signal was
dismissed as 'won't fix' here:
https://bz.apache.org/bugzilla/show_bug.cgi?id=50669
To reproduce, run `apache2 -DFOREGROUND` and resize your terminal.
If you don't have an apache config at hand, you may click here:
https://gitpod.io/#https://github.com/meysholdt/apache-in-gitpod-example/tree/apache_sigwinch_issue
This launches a Docker container on the server side with Apache to reproduce
the issue and an IDE in your browser. You also get a Bash Terminal in your
browser where you can interact with Apache. You'll need to go through Github
OAuth.
So, in summary:
* How can I run apache as a foreground process without having it killed by the
next terminal resize?
* Could Apache maybe *not* listen to SIGWINCH when arg -DFOREGROUND is used?
