# BST-TIMEOUT: 300   # MEASURED, not predicted: elapsed=32s over 49 cases on a

#                    # the image was built from) -- 49 being what this suite ran
#                    # BEFORE the merge against main dropped its system-ui case;
#                    # it runs 48 now, so the measured bound is if anything
#                    # looser and every figure below belongs to that 49-case run.
#                    # Read off this suite's own
#                    # ==BST-SUITE elapsed= line. So the bound is ~9.4x the run.
#                    # That is the convention at this size -- 57-fontconfig sits
#                    # at 300 on a measured 76s, and 99-ttf-hunkyfonts at 300 on
#                    # a measured 35s -- and reading the line rather than
#                    # reasoning about it is the correction BRINTOS-1449 had to
#                    # ship when it guessed at 48x the truth.
#                    #
#                    # THE "NO PROBE, SO CHEAPER PER CASE" PREDICTION WAS WRONG,
#                    # AND IN THE UNSAFE DIRECTION. This suite starts no probe
#                    # binary, so an earlier draft of this header reasoned it
#                    # would come in under 99-ttf-hunkyfonts' measured
#                    # 0.48-0.57 s/case. It runs at 0.65 s/case (32s / 49),
#                    # ABOVE 99-cantarell-fonts' 0.60 s/case (30s / 50) measured
#                    # in the same boot -- which does drive a probe.
#                    #
#                    # The reason is that per-case cost here is dominated by
#                    # EXECS, not by what is exec'd: this suite's consumer block
#                    # runs seven fc-match calls, two fc-list calls, an fc-cache
#                    # and a recursive `grep -ril` over /etc/fonts, so its
#                    # exec-to-case ratio is higher than a suite that starts one
#                    # probe and reads its output. Recorded because the
#                    # prediction is the natural one to make and it does not
#                    # hold; on this arm a process's memory is not returned when
#                    # it exits, so exec COUNT is the thing to reason about.

# ttf-abyssinica 2.100 -- Abyssinica SIL, SIL International's Ethiopic-script
# font for Amharic, Tigrinya and Ge'ez, under OFL-1.1. meta-openembedded
# meta-oe/recipes-graphics/ttf-fonts/ttf-abyssinica_2.100.bb.
#
# ============================================================================
# THE POINT OF THIS FONT IS THE ETHIOPIC CHARSET, SO THAT IS WHAT THE SUITE
# CHECKS -- NOT ONLY THAT A FILE ARRIVED.
# ============================================================================
#
# Every ordinary font assertion in this suite -- the pinned file list, the
# digest, fc-cache, fc-list, fc-query, fc-match -- is satisfied by a 331,004-byte
# file with the right name and the right internal name table. NONE of them asks
# whether the thing can write Amharic. The eth-* cases do, by reading the face's
# own charset through fc-query and counting the codepoints it covers in each of
# the five Ethiopic Unicode blocks against a committed control:
#
#     Ethiopic             U+1200..U+137F   358 of 384
#     Ethiopic Supplement  U+1380..U+139F    26 of  32
#     Ethiopic Extended    U+2D80..U+2DDF    79 of  96
#     Ethiopic Extended-A  U+AB00..U+AB2F    32 of  48
#     Ethiopic Extended-B  U+1E7E0..U+1E7FF  28 of  32
#                                           ---
#                                           523 Ethiopic codepoints, of 843
#
# MEASURED (2026-08-30, fontconfig 2.15.0). The counts are less than the block
# sizes because Unicode leaves holes in these blocks and SIL does not draw every
# assigned slot; a control written from the block sizes would fail on a correct
# font. THE COUNTS ARE ASSERTED AND NOT ONLY THE PRESENCE OF EACH BLOCK, because
# presence is the check that passes on a font whose outlines were truncated --
# a broken glyf table still leaves a non-empty range in every block.
#
# ============================================================================
# BEFORE THIS PORT, NOTHING ON THIS IMAGE COVERED AMHARIC AT ALL.
# ============================================================================
#
# MEASURED as a 2x2 on a reconstruction of this image's font tree, with and
# without this package (2026-08-30, fontconfig 2.15.0):
#
#     WITHOUT:  fc-list ":lang=am"  ->  (nothing)
#     WITH:     fc-list ":lang=am"  ->  AbyssinicaSIL-Regular.ttf
#
# So fc-list-lang-am-sole is not a restatement of fc-match-Abyssinica-SIL: it
# says this package is the image's ONLY supplier of the script, which is the
# thing the port exists to change and the thing a later font port could silently
# take over. The face advertises am, gez, ti-er, ti-et, byn, sid, tig and wal
# among 94 language tags.
#
# NOTE ti IS NOT IN THE FACE'S LANG LIST -- ti-er AND ti-et ARE. fontconfig
# normalises a bare `ti` request onto them, so `fc-match :lang=ti` still lands
# here, but a case asserting the literal tag `ti` in the lang list would be
# asserting something false. The suite queries ti-et.
#
# ============================================================================
# ONE FACE, AND `FILES:${PN} = "${datadir}"` IS WHY THE PAYLOAD IS PINNED HARD.
# ============================================================================
#
#     FILES_INFO:ttf-abyssinica  AbyssinicaSIL-Regular.ttf  331,004
#
# READ OFF THE BUILT PACKAGE (pkgdata/runtime/ttf-abyssinica), not predicted
# from the FILES glob -- which is the WHOLE of ${datadir} and would tell you
# nothing. SIL ships Abyssinica as a single Regular weight: there is no Bold, no
# Italic and no BoldItalic to be missing, and a suite assuming a four-face family
# by convention would report three absent files that were never drawn.
#
# The upstream zip carries a good deal MORE than the face -- OFL.txt,
# FONTLOG.txt, README.txt, OFL-FAQ.txt, documentation/ (odt, pdf, doc) and web/
# (.woff, .woff2, an example .css and .html). With `FILES:${PN} = "${datadir}"`
# open that wide, the only thing keeping them out of the image is ttf.inc's
# do_install copying `*.tt[cf]` and nothing else. no-woff asserts that from the
# file layer and pkg-no-doc-package from the package layer, because "the licence
# text is absent" and "the licence text was dropped" look identical otherwise.
#
# NO LICENCE TEXT REACHES THE IMAGE, AND THAT IS THE RECIPE. LIC_FILES_CHKSUM
# points at ${S}/OFL.txt, which do_install does not copy. That is upstream
# Yocto's ordinary behaviour for ttf.inc and not a defect of this port; it is
# recorded here so a reader does not go looking for it.
#
# ============================================================================
# fc-match RESOLVES THE FAMILY TO THIS PACKAGE -- THE TICKET'S REQUIREMENT IN
# ITS LITERAL WORDING. THE "UNPROVIDED FAMILY" HALF IS NOT MET, AND THE REASON
# IS MEASURED.
# ============================================================================
#
# MEASURED (2026-08-30, fontconfig 2.15.0 over this image's whole font tree):
#
#     fc-match "Abyssinica SIL"  ->  /usr/share/fonts/truetype/AbyssinicaSIL-Regular.ttf
#     fc-match sans-serif        ->  LiberationSans-Regular.ttf   (unchanged)
#     fc-match serif             ->  LiberationSerif-Regular.ttf  (unchanged)
#     fc-match monospace         ->  SourceCodePro-Regular.otf    (unchanged)
#
# The ticket also asks that "fc-match for a family name this package does not
# provide is asserted to NOT resolve here, so a mis-scoped fontconfig entry fails
# rather than passing by accident". THAT CASE IS NOT IN THIS SUITE, because the
# 2x2 shows the premise does not hold on this image and the case would be red for
# a reason that has nothing to do with a mis-scoped entry:
#
#     WITHOUT this port:  "Zzzz Nonexistent" -> LiberationMono-Regular.ttf
#     WITH this port:     "Zzzz Nonexistent" -> AbyssinicaSIL-Regular.ttf
#
# EVERY unmatched family name moves, not names resembling this one: "Comic Sans
# MS" and "Hunky Mono" move too, and so does a name that resembles this family
# but is not it. fc-match never returns nothing -- it always returns a best
# match -- so the image has an arbitrary unknown-family incumbent either way, and
# this port becomes it.
#
# THREE EXPLANATIONS WERE RULED OUT BY MEASUREMENT, NOT BY ARGUMENT:
#   - a fontconfig fragment from this package: `grep -ril abyssinica /etc/fonts`
#     returns nothing (this is what conf-no-fragment asserts on target);
#   - language coverage: this face carries 94 lang tags against Liberation's
#     193, so the WINNER HAS FEWER;
#   - spacing: `fc-match "Zzzz Nonexistent:spacing=100"` still lands here.
# Which comparator in fontconfig's sort actually decides it was NOT established,
# and is not guessed at here.
#
# So the ticket's INTENT -- that this package must not capture matching it has
# no business capturing -- is asserted by the two cases that can carry it:
# conf-no-fragment (this package ships no fontconfig entry at all) and the three
# fc-match-generic-* cases (the generics real consumers actually resolve keep
# their incumbents). The unknown-family fallback is recorded here as a measured
# observation and deliberately NOT asserted: it is a whole-image property that
# the next font port will move again, so a case pinning it would be rot rather
# than coverage.
#
# ============================================================================
# ORDERING AND THE fc-cache BOUND
# ============================================================================
#
# `fc-cache`, NOT `fc-cache -f`, SINCE BRINTOS-1725. The -f rebuilt every
# directory whether or not its cache was valid, which means mapping every face on
# the image; that ticket MEASURED four font suites parking here on an image whose
# largest face had gone over the line. Without -f, fc-cache rebuilds only what is
# stale. This face is 331,004 bytes, which is LARGER than any face those four
# suites walk, so this suite keeps the bound and the last-place ordering rather
# than reasoning that it is safe.
#
# BRINTOS-WORKAROUND: linux-in-the-browser#165 revisit -- drop -f so only a stale
# cache is rebuilt, bound the call, and order the consumer block last; all three
# go when the mmap population path tolerates a parking read.

# (BRINTOS-1149 established that and filed it as linux-in-the-browser#177). The
# harness reports the deficit but computes its pass count as total-minus-
# failures, so THE DROPPED LINE IS COUNTED AS A PASS. A nothing-case therefore
# stands in that position and the eaten line costs nothing; every real case below
# is still counted. It sits ahead of the `require` guards deliberately, because a

# THE THREE GENERICS THIS PORT DOES **NOT** TAKE OVER, ASSERTED FROM THIS SIDE.
# This family appears on no preference list in this image's /etc/fonts (asserted
# directly above) and is not monospaced, so all three generics keep their
# incumbents. This is NOT a restatement of the fc-match-* cases: those stay green
# if installing this family ALSO displaced a generic, which is precisely what
# installing ttf-inconsolata did to `monospace` one ticket after it landed. The
# incumbents are named so a red says which one moved.
#
# system-ui IS DELIBERATELY NOT ASSERTED HERE, AND THAT IS A MEASURED DECISION
# RATHER THAN AN OMISSION. On the image this port was built and verified on it
# DID move: `fc-match system-ui` answered Liberation Mono one ticket earlier and
# `Abyssinica SIL` here. That is not a preference list biting -- 60-latin.conf:77
# does carry a <prefer> alias for system-ui, and 99-cantarell-fonts established
# by measurement (on target AND off it, against a native fontconfig 2.15.0) that
# the alias does NOT decide the answer. system-ui is seeded as a generic by
# nothing, so the query behaves as an UNMATCHED FAMILY NAME and takes whatever
# the image's unknown-family fallback currently is -- exactly as
# "Zzzz Nonexistent" does, and the two moved together in the same 2x2.
#
# ON THE MERGED TREE IT DOES NOT MOVE AT ALL, AND THAT IS WHY THERE IS NO CASE.
# Measured at the merge against `main`: system-ui ranks 1 Roboto, 2 Abyssinica
# SIL, 3 Liberation Mono, 4 Liberation Sans -- ttf-roboto's twenty faces keep the
# fallback, and this one face ranks second. An `Abyssinica SIL` assertion here
# would have been green on this branch's own pre-merge image and RED the moment
# it landed, which is the whole reason this port asserts the three BOUND generics
# and nothing else. The value lives in 99-cantarell-fonts, which asserts it as
# `Roboto` from the side that owns it.
#
# THE DURABLE REPAIR IS NOT THIS PORT'S TO MAKE: give system-ui a real binding
# rather than a <prefer> list that does not bite, and it stops being a fallback
# incumbent that every font port re-points. That is distro policy, out of scope
# for a package port, and recorded in this ticket's design doc.
# AMENDED FOR BRINTOS-1729 (ttf-tlwg), WHICH TAKES sans-serif AND serif
# IMAGE-WIDE. ttf-tlwg ships ten <alias><prefer> fragments into /etc/fonts/conf.d
# at 64; <prefer> PREPENDS ahead of the generic while 30-liberation-aliases.conf's
# <accept> only APPENDS behind it, so Kinnari takes `serif` and Waree takes
# `sans-serif` for every suite on this image at once. It is CONFIGURATION-driven,
# so it does not depend on how large the font set is. monospace is unaffected --
# source-code-pro-fonts' own <prefer> loads at 44, ahead of these. THE CASE IS
# AMENDED, NOT DELETED: what it asserts is that THIS port does not take a generic,
# which is still true, and only the value it is compared against moved.
