webrunner_smoketests flakes due to blobfs capacity assertion failure |
||||||||||||||||||||
Issue descriptionOn the Fuchsia x64 bot (https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Fuchsia%20x64) we see flakes due to blobfs capacity check failures, e.g. in runs https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Fuchsia%20x64/26669 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Fuchsia%20x64/26674 https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Fuchsia%20x64/26670 with output including: [00101.478] ASSERT FAILED at (system/ulib/blobfs/writeback.cpp:202): blocks <= capacity_ [00101.478] Requested txn (5329 blocks) larger than buffer

Run https://ci.chromium.org/p/chromium/builders/luci.chromium.ci/Fuchsia%20x64/26674 also failed to install castrunner_tests, for the same reason.

The following revision refers to this bug: https://chromium.googlesource.com/chromium/src.git/+/22c7b4216d6cf874f7bbc0aa6aead31498c811e8 commit 22c7b4216d6cf874f7bbc0aa6aead31498c811e8 Author: Fabrice de Gans-Riberi <fdegans@chromium.org> Date: Thu Jan 03 18:21:58 2019 [Fuchsia] Disable integration tests on the waterfall. Fuchsia integration tests have been flaking on the waterfall. Disable them until the underlying issue is fixed. This also separates castrunner unit tests and integration tests in two different test suites.

Remove webrunner_browsertests from the main waterfall Fuchsia x64 bot, since the suite sometimes fails to install, with a blobfs assertion. Enable castrunner_integration_tests and webrunner_browsertests, which were entirely disabled by https://chromium-review.googlesource.com/c/chromium/src/+/1393887, to run on the Fuchsia FYI bots, to provide some coverage without blocking Chromium's waterfall/CQ with installation flakes.
