Bisect failing compare samples step with error reading filename |
|||||
Issue descriptionThese are both on the exact same buildslave (build107-b4). Could it be a problem with the disk on the slave? https://build.chromium.org/p/tryserver.chromium.perf/builders/android_nexus6_perf_bisect/builds/2761 https://build.chromium.org/p/tryserver.chromium.perf/builders/android_nexus6_perf_bisect/builds/2762 https://build.chromium.org/p/tryserver.chromium.perf/builders/android_nexus6_perf_bisect/builds/2762/steps/Compare%20samples/logs/stdio Traceback (most recent call last): File "/b/c/b/android_nexus6_perf_bisect/catapult/tracing/bin/compare_samples", line 54, in <module> sys.exit(Main(sys.argv)) File "/b/c/b/android_nexus6_perf_bisect/catapult/tracing/bin/compare_samples", line 48, in Main args.format File "/b/c/b/android_nexus6_perf_bisect/catapult/tracing/tracing/metrics/compare_samples.py", line 54, in CompareSamples metric File "/b/c/b/android_nexus6_perf_bisect/catapult/third_party/vinn/vinn/_vinn.py", line 186, in RunFile return _RunFileWithD8(temp_boostrap_file, js_args, v8_args, stdout, stdin) File "/b/c/b/android_nexus6_perf_bisect/catapult/third_party/vinn/vinn/_vinn.py", line 265, in _RunFileWithD8 'Exception raised when executing %s:\n%s' % (js_file_path, out)) RuntimeError: Exception raised when executing /tmp/tmplDuJLf/_tmp_boostrap.js: /tracing/base/xhr.html:132: Error: Error loading file when reading/b/c/b/android_nexus6_perf_bisect throw new Error(ex + ' when reading' + filename); ^ Error: Error loading file when reading/b/c/b/android_nexus6_perf_bisect at Object.getSync (/tracing/base/xhr.html:132:13) at parseFiles (/b/c/b/android_nexus6_perf_bisect/catapult/tracing/tracing/metrics/compare_samples_cmdline.html:140:24) at Object.compareCharts (/b/c/b/android_nexus6_perf_bisect/catapult/tracing/tracing/metrics/compare_samples_cmdline.html:248:19) at eval (/b/c/b/android_nexus6_perf_bisect/catapult/tracing/tracing/metrics/compare_samples_cmdline.html:262:56) at Object.loadHTMLFile (/b/c/b/android_nexus6_perf_bisect/catapult/third_party/vinn/vinn/html_imports_loader.js:140:5) at /b/c/b/android_nexus6_perf_bisect/catapult/third_party/vinn/vinn/d8_bootstrap.js:150:19

I'll take a look.

Kinda looks like it's having trouble running cc_perftests? The "Compare Samples" step failing is a bit misleading since it's actually "Gathering Reference Values" that's failing to get any values, even though the steps shows up green.
/usr/bin/python /b/c/b/android_nexus6_perf_bisect/src/build/android/test_runner.py gtest --release -s cc_perftests --verbose
I 0.002s Main command: /b/c/b/android_nexus6_perf_bisect/src/build/android/test_runner.py gtest --release -s cc_perftests --verbose
C 0.003s Main Could not find apk or executable for cc_perftests
E 0.003s Main Unrecognized error occurred.
Traceback (most recent call last):

Kinda seems like there's 2 problems here, it's really not clear that what really went wrong was "Gathering Reference Values" failed, and that the bisect bot is failing to run cc_perftests. I'll log bugs for those.
