From 9dd7a8b9376b4fb6b82422899e0ed7b8606c73ce Mon Sep 17 00:00:00 2001 From: Andrew Robbins Date: Thu, 27 Dec 2018 23:37:07 -0500 Subject: [PATCH] Require a recent fontforge for reproducibility The required version is set to 20171220 which is the earliest date from which fontforge built from source was able to produce the non-LGC subset of DejaVu deterministically. "20171220" refers to upstream revision 69e561773b91e37096a855f0353b1d6781a61250 Note there was not an actual dejavu-fonts release made on 2017-12-20; the date is intended to be both a reference point, as previously described, and a mechanism to prevent non-deterministic fonts being produced by Libreboot's build system due to an unsupported version of fontforge being used. --- scripts/generate.pe | 4 ++-- scripts/generate.py | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/scripts/generate.pe b/scripts/generate.pe index 5d9d03d..144e8b1 100755 --- a/scripts/generate.pe +++ b/scripts/generate.pe @@ -16,8 +16,8 @@ def_gen_flags = 0x20 + 0x40 + 0x800 exp_gen_flags = def_gen_flags + 8 -if ($version < "20080330") - Error("Your version of FontForge is too old - 20080330 or newer is required"); +if ($version < "20171220") + Error("Your version of FontForge is too old - 20171220 or newer is required"); endif # FoundryName is not used in TTF generation SetPref("FoundryName", "DejaVu") diff --git a/scripts/generate.py b/scripts/generate.py index 467d52b..168a2be 100755 --- a/scripts/generate.py +++ b/scripts/generate.py @@ -7,7 +7,7 @@ # chmod +x generate.pe # ./generate.pe *.sfd import fontforge, sys; -required_version = "20080330" +required_version = "20171220" # font generation flags: # omit-instructions => do not include TT instructions (for experimental typefaces) -- 2.7.4
