Subject: libapache-mod-evasive: reproducible-builds: Embedded build paths in mod_evasive20.so

[Message part 1 (text/plain, inline)]

Source: libapache-mod-evasive
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: buildpath
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

The build path is embedded in /usr/lib/apache2/modules/mod_evasive20.so:

  https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/diffoscope-results/libapache-mod-evasive.html

  /build/1st/libapache-mod-evasive-1.10.1/mod_evasive20.c:713
  vs.
  /build/2/libapache-mod-evasive-1.10.1/2nd/mod_evasive20.c:713

The attached patch to debian/rules fixes this by adding
-ffile-prefix-map to the call to apxs2.

According to my local tests, with this patch applied
libapache-mod-evasive should build reproducibly on
tests.reproducible-builds.org!

Thanks for maintaining libapache-mod-evasive!

live well,
  vagrant
