Subject: snacc: reproducible builds: timestamp embedded in header files

Date: Fri, 29 Apr 2022 16:17:48 -0700

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

Source: snacc
Severity: normal
Tags: patch
User: reproducible-builds@lists.alioth.debian.org
Usertags: timestamps
X-Debbugs-Cc: reproducible-bugs@lists.alioth.debian.org

Various header files embed the timestamp when it was generated in
comments:

  https://tests.reproducible-builds.org/debian/rb-pkg/bookworm/amd64/diffoscope-results/snacc.html

  /usr/include/snacc/c/asn-useful.h

  ·*····This·.h·file·was·generated·by·snacc·on·Fri·May·19·17:42:30·2023
  vs.
  ·*····This·.h·file·was·generated·by·snacc·on·Sun·Apr·17·13:25:08·2022


The attached patch fixes this by removing the timestamps from the code
that generates the header files.


With this patch applied, snacc should become reproducible on
tests.reproducible-builds.org!


live well,
