From 87731820926cd6f51879d7b89687bfec2e615b3d Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 27 Feb 2016 23:03:15 +0100 Subject: [PATCH] support/download: really, really make git archives reproducible The way we use it, gzip will store the current time in the header, which leads to unreproducible archives. Fix that by telling gzip to not store the name and date of the file it compresses, with the -n option. Since it compresses its stdin, there was already no filename stored; now there's even no date stored. Note: gzip has had -n since at least 1.2.4, released in 1993, so virtually every gzip out there nowadays has it. Signed-off-by: "Yann E.
