# ttf-liberation-sans-narrow 1.07.4 -- the four Liberation Sans Narrow faces,
# packaged apart from the rest of the family because they come from a different
# upstream release. meta-openembedded
# meta-oe/recipes-graphics/ttf-fonts/ttf-liberation-sans-narrow_1.07.4.bb.
#
# ============================================================================
# THE PAYLOAD IS UNDER /usr/share/fonts/TTF, NOT truetype/. THAT IS MEASURED,
# AND IT IS NOT WHAT THE TICKET PREDICTED.
# ============================================================================
#
# BRINTOS-1722 describes the files as landing under ${datadir}/fonts/truetype/
# and the recipe as "pruning everything but the narrow faces out of the tarball".
# Both halves are wrong about the mechanism, and the first is wrong about the
# result. What the recipe actually does, read off ttf.inc plus the .bb:
#
#   ttf.inc do_install         install every *.tt[cf] -> ${datadir}/fonts/truetype/
#                              (all SIXTEEN faces: Mono, Sans, SansNarrow, Serif)
#   do_install:append          install LiberationSansNarrow*.ttf -> ${datadir}/fonts/TTF/
#                              install the fontconfig fragment, install License.txt
#                              rm -rf ${D}${datadir}/fonts/truetype
#
# So the last line removes the truetype directory WHOLESALE. There is no
# face-by-face prune, and nothing this package installs ends up under truetype/.
# Every case below is scoped to TTF/; a suite written to the ticket's wording
# would have asserted an empty set and passed.
#
# The ticket's underlying worry is still the right one and is asserted here in
# the form the code actually takes: prune-nonnarrow-absent checks the twelve
# non-narrow basenames are not under TTF/, and prune-truetype-unowned checks --
# from the dpkg database, not the filesystem, because truetype/ has four other
# tenants -- that this package claims no path there at all. Those two are what
# stand between this port and a third Liberation release colliding with
# ttf-liberation 0.2 and poky's liberation-fonts 2.1.5, which share all twelve
# basenames with this tarball at three different sizes.
#
# ============================================================================
# THIS PORT IS THE SOLE TENANT OF /usr/share/fonts/TTF AND OF /etc/conf.avail,
# SO NO NEIGHBOURING SUITE IS AMENDED. THAT WAS SWEPT, NOT ASSUMED.
# ============================================================================
#
# Read off the last COMPLETE image (BRINTOS-1714, 2026-08-27), /usr/share/fonts
# carried exactly four subdirectories -- cantarell(2), terminus(19),
# truetype(27), ttf(23) -- and no TTF. /etc/conf.avail did not exist. So unlike
# the sibling ttf-liberation port, which landed twelve files into the shared
# truetype/ and had to amend three cases in two suites, this one adds a
# directory nothing else reads.
#
# The neighbours were swept anyway, by what they COUNT rather than by name: no
# suite counts /usr/share/fonts whole-tree and none pipes a bare fc-list into
# wc. The one whole-directory enumeration in the font suites --
# 99-liberation-fonts:99 -- names /usr/share/fonts/truetype explicitly, which
# this port does not write to. 57-fontconfig's conf-avail cases count
# /usr/share/fontconfig/conf.avail, fontconfig's own bundled set, and are
# bounded from below; /etc/conf.avail is a different directory and does not
# reach them. 57-fontconfig's etc-confd is an existence check on
# /etc/fonts/conf.d, which this package creates empty and does not populate.
#
# ============================================================================
# THE RECIPE'S OWN FONTCONFIG FRAGMENT IS NEVER READ -- AND IT WOULD CHANGE
# NOTHING IF IT WERE. BOTH HALVES MEASURED.
# ============================================================================
#
# The recipe creates ${sysconfdir}/fonts/conf.d/ and then installs its fragment
# to ${sysconfdir}/conf.avail/30-${PN}-sans.conf -- /etc/conf.avail, with no
# fonts/ component. The image's /etc/fonts/fonts.conf carries exactly one
# include, `<include ignore_missing="yes">conf.d</include>`, resolved relative
# to /etc/fonts. There is no conf.avail include anywhere. So the shipped
# fragment is inert: conf-not-in-confd pins that, and it is stated as a fact
# about this recipe rather than as a defect this port introduced.
#
# It costs nothing, and that is the second measurement rather than an inference.
# The fragment aliases Arial Narrow <-> Liberation Sans Narrow in both
# directions. fontconfig 2.15.0's own 30-metric-aliases.conf -- which IS active,
# symlinked into /etc/fonts/conf.d from /usr/share/fontconfig/conf.avail --
# already carries both:
#
#     line 603  <alias binding="same"><family>Arial Narrow</family>
#                 <accept><family>Liberation Sans Narrow</family></accept></alias>
#     line 344  <alias binding="same"><family>Liberation Sans Narrow</family>
#                 <default><family>Arial Narrow</family></default></alias>
#
# The recipe's fragment is a verbatim duplicate of stock fontconfig. Installing
# it at the correct path would add nothing; leaving it at the wrong one removes
# nothing. NO BBAPPEND, therefore, and no workaround marker is owed: nothing was
# worked around. conf-aliases-are-stock asserts the stock file still carries the
# alias, so the day fontconfig drops it this suite says so rather than silently
# depending on a fragment that is not being read.
#
# This is also why fc-match-arial-narrow is a POSITIVE case here. "Arial Narrow"
# is a family this package does not provide, and it nevertheless resolves into
# this package -- correctly, through stock metric aliasing. The ticket asks for
# an unprovided family that must NOT resolve here; Arial Narrow is not it, and
# neither is Helvetica Narrow, which stock fontconfig aliases to Arial Narrow.
# fc-match-liberation-sans-elsewhere is the real negative: "Liberation Sans" is
# one word from ours, is provided by poky's liberation-fonts on this image, and
# must resolve to ITS file. That is the mis-scoping guard, and it is the same
# guard as prune-truetype-unowned seen from the consumer side.
#
# ============================================================================
# NO NEW MAXIMUM FOR THE mmap REFUSAL BAND.
# ============================================================================
#
# File-backed mmap is refused on this arm above a mapping-length threshold and
# the consumer parks rather than falling back (linux-in-the-browser#165,
# bracketed by BRINTOS-1450 between ~66 kB and 577,708 bytes). The four faces
# here are 110,560 / 113,304 / 129,448 / 133,540 bytes. The largest is smaller
# than the SMALLEST of the twelve poky Liberation faces this image already scans
# on every fc-cache (281,536, range to 415,816), so this port adds no new
# maximum and nothing to the band #165 is about. No hold-out, no marker.
