From 3871d417ad4a41117f754efeb4fb0af698b51d5d Mon Sep 17 00:00:00 2001 From: Siwen Yu Date: Sat, 31 Oct 2026 12:21:09 +0800 Subject: [PATCH] test(agent): make the cancelled-retry assertion match the property MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TestCancelledRunMakesNoFurtherRequest failed on master's post-merge run of 8d1ccb8 with "OnRetry fired 1 times, want 0" — the second time this has happened (issue #295, first seen on #294). The assertion was stricter than the property the test is named for. If the cancel lands after the retry decision but before the backoff's sleep observes it, OnRetry announces the attempt the sleep then abandons — and no second request is made, which is the fact that matters. The counter also crossed goroutines untyped. It is now atomic and asserts at most one announcement, while the request count keeps its stricter "exactly one" check. Tested at -count=50 and with the whole package at -count=3 (the gate that failed), plus the race detector across the repository.
