From mboxrd@z Thu Jan 1 00:00:00 1970 From: Aaron Sierra Date: Mon, 13 Jul 2020 13:47:49 -0500 Subject: [Buildroot] [PATCH RESEND 0/2] Use bzip2 for X11 PFC font compression Message-ID: <20200713184751.23534-1-asierra@xes-inc.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Gzip has been used as the default compressor for PCF fonts, but this series changes the default compressor to bzip2 for a few reasons: 1. Even with the latest gzip, these seemingly synonymous pipelines produce different output, but this issue does not exist with bzip2: $ cat /path/to/file | gzip > /path/to/file.gz $ gzip < /path/to/file > /path/to/file.gz 2. Prior to gzip 1.10, the compression pipeline used with PCF fonts was not reproducible due to the implicit -N/--name injecting a timestamp: * cat /path/to/file | gzip > /path/to/file.gz 3. The BR2_USE_WCHAR dependency of the gzip package tarnishes the appeal of using host-gzip to provide reproducible output. After building all PCF fonts under package/x11r7, the bzipped output is slightly smaller: gzip - 42392 KB bzip2 - 40500 KB This change does not affect encodings, which will continue to be gzipped. The upstream sources don't support bzip2 compression and their compression pipeline happens to be reproducible before gzip 1.10: * gzip < /path/to/file > /path/to/file.gz -Aaron Aaron Sierra (2): package/x11r7/xapp_mkfontscale: support bzip2 package/x11r7/xfont_font-*: make outputs reproducible package/x11r7/xapp_mkfontscale/Config.in | 1 + package/x11r7/xapp_mkfontscale/xapp_mkfontscale.mk | 6 ++++-- .../xfont_font-adobe-100dpi/xfont_font-adobe-100dpi.mk | 1 + .../x11r7/xfont_font-adobe-75dpi/xfont_font-adobe-75dpi.mk | 1 + .../xfont_font-adobe-utopia-100dpi.mk | 1 + .../xfont_font-adobe-utopia-75dpi.mk | 1 + .../x11r7/xfont_font-arabic-misc/xfont_font-arabic-misc.mk | 1 + package/x11r7/xfont_font-bh-100dpi/xfont_font-bh-100dpi.mk | 1 + package/x11r7/xfont_font-bh-75dpi/xfont_font-bh-75dpi.mk | 1 + .../xfont_font-bh-lucidatypewriter-100dpi.mk | 1 + .../xfont_font-bh-lucidatypewriter-75dpi.mk | 1 + .../xfont_font-bitstream-100dpi.mk | 1 + .../xfont_font-bitstream-75dpi.mk | 1 + .../xfont_font-cronyx-cyrillic.mk | 1 + .../x11r7/xfont_font-cursor-misc/xfont_font-cursor-misc.mk | 1 + .../x11r7/xfont_font-daewoo-misc/xfont_font-daewoo-misc.mk | 1 + package/x11r7/xfont_font-dec-misc/xfont_font-dec-misc.mk | 1 + package/x11r7/xfont_font-isas-misc/xfont_font-isas-misc.mk | 1 + package/x11r7/xfont_font-jis-misc/xfont_font-jis-misc.mk | 1 + .../x11r7/xfont_font-micro-misc/xfont_font-micro-misc.mk | 1 + .../xfont_font-misc-cyrillic/xfont_font-misc-cyrillic.mk | 1 + package/x11r7/xfont_font-misc-misc/xfont_font-misc-misc.mk | 1 + package/x11r7/xfont_font-mutt-misc/xfont_font-mutt-misc.mk | 1 + .../xfont_font-schumacher-misc.mk | 1 + .../xfont_font-screen-cyrillic.mk | 1 + package/x11r7/xfont_font-sony-misc/xfont_font-sony-misc.mk | 1 + package/x11r7/xfont_font-sun-misc/xfont_font-sun-misc.mk | 1 + .../xfont_font-winitzki-cyrillic.mk | 1 + 28 files changed, 31 insertions(+), 2 deletions(-) -- 2.17.1
