From 97e9b5e6f18705666b9d622b9eab0b31836321ba Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 21 Sep 2026 19:21:32 +0000 Subject: publish-apk: fix a SIGPIPE this repo's own README warns about The zip check used `unzip -l | grep -q`. Under pipefail, grep exits on its first match and SIGPIPEs unzip, so the pipeline fails on a perfectly valid file. It rejected a real 112MB APK as 'not an APK'. That exact trap is in the README's table, written after it broke crash detection in android-launch-check. Knowing about a trap is not the same as not falling into it, which is the argument for these scripts existing at all. Captures the listing first and tests it with `case`, and the new test builds a 300-entry zip so grep matches long before the listing ends -- which is when SIGPIPE actually bites. A single-entry fixture would have passed either way.
