From 76b51f90c0e393349dd0c71d7e6cf82fbc094282 Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 2 Jan 2016 12:35:49 +0100 Subject: [PATCH] support/download: generate reproducible Hg archives When hg directly creates the output file, the hash for that file changes everytime. However, if we just tell hg to output the archive on stdout and we do the redirect to the file, then the archive is reproducible. (The reason is that in the first case, a temporary file is created and then compressed, and gzip is adding the filename and its timestamp in the gzip header, while in the second case, there is no temporary file, and thus no timestamp and thus it is reproducible.)
