From 0da7da8391cfb27a809b3fea7e0f50dd64d018c8 Mon Sep 17 00:00:00 2001 From: kennytm Date: Wed, 1 Aug 2018 18:03:19 +0800 Subject: [PATCH] Align 6-week cycle check with beta promotion instead of stable release. The regression check is to make beta promotion easier, so it makes more sense to use the Tuesday of the release week (T-2) as the end point of the regression prevention, instead of Thursday (T-0). But since the beta promotion PR is sent at Tuesday evening at UTC, the protection should include the whole Tuesday as well, meaning the 6-week cycle will start from Wednesdays. This will also move the start of the regression protection week one day earlier. --- src/ci/docker/x86_64-gnu-tools/checktools.sh | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/src/ci/docker/x86_64-gnu-tools/checktools.sh b/src/ci/docker/x86_64-gnu-tools/checktools.sh index 16055078ad5..d876cb7f37a 100755 --- a/src/ci/docker/x86_64-gnu-tools/checktools.sh +++ b/src/ci/docker/x86_64-gnu-tools/checktools.sh @@ -17,9 +17,11 @@ TOOLSTATE_FILE="$(realpath $2)" OS="$3" COMMIT="$(git rev-parse HEAD)" CHANGED_FILES="$(git diff --name-status HEAD HEAD^)" -SIX_WEEK_CYCLE="$(( ($(date +%s) / 604800 - 3) % 6 ))" -# ^ 1970 Jan 1st is a Thursday, and our release dates are also on Thursdays, -# thus we could divide by 604800 (7 days in seconds) directly. +SIX_WEEK_CYCLE="$(( ($(date +%s) / 86400 - 20) % 42 ))" +# ^ Number of days after the last promotion of beta. +# Its value is 41 on the Tuesday where "Promote master to beta (T-2)" happens. +# The Wednesday after this has value 0. +# We track this value to prevent regressing tools in the last week of the 6-week cycle. touch "$TOOLSTATE_FILE" @@ -98,7 +100,7 @@ change_toolstate() { if python2.7 "$CHECK_NOT" "$OS" "$TOOLSTATE_FILE" "_data/latest.json" changed; then echo 'Toolstate is not changed.
