R19 raised two things about this comment. One resolved itself: it used to explain why the
matrix had no API 37 row at all, and #56 added the gating row, so that half is gone.
The other survived, and this is it. The comment read
api-level must be "37.0". A bare 37 is not an SDK package and fails during setup
The second sentence is true and was measured -- it cost a run to find. The first overstates
it. What must be true is that the api-level is a POINT release; 37.0 is one of several.
api37-debug.yml's own input descriptions already say so:
API level, as the SDK spells it. 37.0, 37.1, 37.2-beta3, 36 ...
System image target. android-37.1 and 37.2-beta* ship ONLY as google_apis_ps16k
and docs/api-37-emulator-crash.md measures android-37.0 rev 6 and android-37.1 rev 8 side
by side, both aborting. So the repo already knows 37.1 exists and behaves the same; only
this comment implied otherwise.
That matters for the reader it is written for. Someone debugging this row and wondering
whether a newer image helps reads "must be 37.0" as a constraint and stops. The measured
answer is that it does not help, which is a better thing to learn than a rule that is not
one -- and the ps16k-only wrinkle above 37.0 is the detail that would actually bite them.
Comment only. No job, matrix, filter or gating behaviour changes. actionlint clean at the
pinned digest.
Closes#28.
RealMediaBenchmark's class KDoc said:
Populate with:
adb push <file>.mp4 /sdcard/Android/data/org.libremediaconverter/files/
Twelve lines below, the `samples` property KDoc -- on `get() = context.filesDir` -- says:
Internal storage, not the external files dir. Files placed in the external dir by
`adb push` or `adb shell cp` stay owned by the shell user, and the app then gets
EACCES trying to read them -- which presents as an unparseable input rather than a
permission problem.
Different directories, and the second exists specifically to explain why the first fails.
Anyone following the class KDoc stages files the benchmark cannot read, gets a skip, and
reads the skip as "not staged yet" -- the failure mode the property KDoc warns about, walked
into by the instruction in the same file.
The fix is not a corrected command. Restating the mechanism in a second place is what let
these drift, and a replacement command I have not executed would be the same defect with a
fresher date. The class KDoc now names [samples] as the single place that answers it.
Two things added that are checkable rather than remembered: the exact filenames the tests
look for, via [H264_SAMPLE] and [AV1_SAMPLE] -- the old text said `<file>.mp4`, so even the
right directory left you guessing -- and a note that the two skips every green E2E leg
reports are these.
Not claimed: that the benchmark misbehaves on CI. An earlier version of the ticket said so;
it was wrong, and measuring settled it -- both tests report SKIPPED on the gating legs, the
guards work, and "harmless in CI" is accurate. The failure that prompted the look is
Media3EngineTest, tracked as #102.
Closes#101.
ConversionViewModelProbeFailureTest's pickedProbe() helper held:
val ready = awaitState(viewModel.state, "Ready with a probe") {
it is ConversionState.Ready && it.input.probe != null
}
assertNull("nothing here should reach a terminal failure", (ready as? ConversionState.Failed))
The predicate requires `Ready`. `Ready` and `Failed` are sibling subtypes of one sealed
interface, so `ready as? Failed` is always null and the assertNull could never fire. R26
filed this PLAUSIBLE on types read; it is measured now.
Flipping the line to assertNotNull failed 3 of the 4 tests in the class -- three, because
pickedProbe() has three callers, which is also why a dead line here was worth removing
rather than shrugging at: it read as coverage in a helper the whole class depends on.
Deleted rather than replaced. There is nothing for a live assertion to add: a pick that
ended in Failed never satisfies the predicate, so awaitState fails on its timeout naming
what it was waiting for -- "Ready with a probe" -- which is a better failure message than
the assertion would have produced. The comment now says that, so the next reader does not
re-add the guard the predicate already is.
This is the ninth vacuous assertion this line of work has turned up, and the pattern is
consistent: they hide in helpers, they pass, and they look like care. The suite is green
before and after, which is exactly the point -- deleting a dead assertion cannot change a
result, and if it had, the line was not dead.
Closes#35.
The shellcheck step added a few hours ago reads `git ls-files '*.sh'`. That is four files.
It does not read the inline `run:` blocks, and a good deal of this repo's bash lives there:
the release verification in build.yml, the emulator setup and teardown in status_check.yml
and api37-debug.yml. "shellcheck runs in CI" was true of the files and not of the blocks,
and CLAUDE.md said so rather than pretending otherwise.
actionlint closes that half. It parses each workflow and runs shellcheck over every `run:`,
on top of its own checks for expression syntax, `needs:` references, matrix keys and action
input names.
Pinned by digest, for the reason shellcheck is pinned -- a new rule making untouched files
fail is a red build whose diff cannot explain it -- and for a second reason of its own.
actionlint's documented install is
bash <(curl -s https://raw.githubusercontent.com/.../download-actionlint.bash)
off a moving branch. Running that in a repository that pins every action by SHA would
contradict its own supply-chain posture more than the linter is worth. That is why #70 was
filed instead of bolted onto the shellcheck commit.
It reported exactly one finding, and it is fixed here rather than suppressed: build.yml
parsed `ls` to pick the release APK (SC2012). The glob was already in the line, so a bash
array reads it without the pipe. Gradle's output names have no spaces today, which is the
kind of assumption that holds right up until it does not.
Proved it catches something, rather than trusting a green run: planting `if [ $UNQUOTED =
bad ]` into a build.yml `run:` block produces
shellcheck reported issue in this script: SC2086:info:4:6:
Removed again afterwards. A linter that cannot be shown to catch a plant is not wired in,
it is just running -- and SC2086 in a `run:` block is invisible to the .sh-file step, which
is the whole argument for this commit.
CLAUDE.md loses the "does not cover inline run: blocks" caveat, because it no longer does.
Both linters verified clean at their pinned digests.
Closes#70.
