Bug#1005408: wcwidth: reproducible-builds: build path and timestamp embedded in unicode_versions.py

[Vagrant Cascadian]

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

Builds in a different source directory and at a different time trigger
reproducibility issues in the generated file

The attached patch fixes this by modifying update-tables.py to not add
comment to files it generates, which is presumably safe to do...


With this patch applied, wcwidth should build reproducibly on
tests.reproducible-builds.org!


Thanks for maintaining wcwidth!


live well,
