Bug Description

Adding --with-compat would allow for those compiling dynamic modules separately to include them in the NGINX packages.

This should be considered for Ubuntu and Debian as well.

I realized in IRC I failed to explain properly what happens here.

Related:,270210,270213#msg-270213 and

IN a nut-shell, what --with-compat does is allow people who build NGINX dynamic modules against NGINX in a separate compilation to take their compiled .so modules and include them in the NGINX versions on Ubuntu on their local machine. It would allow someone who, say, built modsecurity for NGINX dynamically and separately to `include` the configuration to enable the modsecurity module for NGINX without having to recompile and install manually alongside it the entire NGINX binary and all the other modules.

From a Security perspective, the only concern would be that third-party modules could be built dynamically then included and activated in individual users' NGINX builds on their own systems. As that happens separately from the NGINX package in Ubuntu, any issues stemming from such inclusions are "End User Problems" and not directly related to the NGINX packages in Ubuntu.

This has some considerations before it gets inserted, as to whether we want users to be able to dynamically compile and include extra modules outside of the binaries we ship already.

However, this bug and the request was prompted thanks to an uptick in requests (10 over 2 days from 10 separate individuals) in my email to enable this functionality both for the PPAs and for Ubuntu.

This sounds like a good idea to me. I can understand that nginx upstream might not want this as a default because it sounds like it'll burn memory in structures, but it sounds wonderful for a general purpose distribution with a variety of users who all want something slightly different out of their webserver.

Note that for Ubuntu, this will not be done for Cosmic - we are too late in the dev cycle to do this for Cosmic, so any changes to this which would add this to the Ubuntu packages will be for D-series (whatever it is named). This needs discussed first, however, before it gets included in the Ubuntu Repositories' versions of NGINX.

The PPAs operate independently and will have the fix whenever the next 'upload' to the PPAs happens.

If we can get with this no downsides, then +1. I agree with Seth's comment.

We are too close to Cosmic release to get this into Cosmic (Won't Fix'd for Cosmic). This will be included in the D-series cycle for Ubuntu.

Mainline PPA packages are building with --with-compat in the staging PPA, if all goes well I'll copy it over to the actual Mainline PPA.

Stable PPA is in progress but more slowly due to other work requirements.

Ubuntu changes are on hold until D-series cycle opens.

PPAs now have --with-compat enabled. Updated packages are copying in from the staging PPAs now.

      nginx-core, which contains only source-tarball-included modules
      and no third-party modules.
    - debian/tests/control: add nginx-core test.
    - debian/apport/ Add apport hooks for additional bug

    - debian/nginx-common.install: Add install rule for apport hooks.
    - d/nginx-{core,light,full,extras}.postinst: Add checks for whether

      starting of the NGINX service during install/upgrade
    - d/control: Add dependencies to nginx-{core,light,full,extras} on
      `iproute2` as the postinst scripts now use `ss` to determine if
      Port 80 is open or not.
    - d/rules: Enable --with-compat build option for all nginx package
      flavors (LP: #1797897)
