Bug 1411358 shows multiple recent cases of linux64/ccov wpt-4 timing out after 7200 seconds (120 minutes). Recent green runs of this task run in 110+ minutes. Other linux64/ccov wpt chunks run in 60 - 90 minutes, so adding more chunks may not be a good option. https://treeherder.mozilla.org/logviewer.html#?job_id=206335195&repo=mozilla-central https://treeherder.mozilla.org/logviewer.html#?job_id=206200103&repo=mozilla-central https://treeherder.mozilla.org/logviewer.html#?job_id=205188757&repo=mozilla-central

Here are the tests that took >10000 ms in a recent run of wpt-4: 10055 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-ks_c_5601-1989.html?15001-16000 10295 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-ksc_5601.html?16001-17000 10308 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-errors-han.html?22001-23000 10352 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-korean.html?15001-16000 10363 /shadow-dom/untriaged/html-elements-in-shadow-trees/inert-html-elements/test-001.html 10477 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-ksc5601.html?14001-15000 10615 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-errors-han.html?19001-20000 10666 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-iso-ir-149.html?14001-15000 10894 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-ksc5601.html?16001-17000 10911 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form-ks_c_5601-1987.html?13001-14000 11234 /encoding/legacy-mb-korean/euc-kr/euckr-encode-form.html?15001-16000 13956 /worklets/paint-worklet-referrer.https.html 14642 /worklets/layout-worklet-referrer.https.html 15363 /worklets/audio-worklet-referrer.https.html 16130 /worklets/animation-worklet-referrer.https.html 26864 /referrer-policy/css-integration/svg/presentation-attribute.html 29878 /referrer-policy/css-integration/svg/processing-instruction.html 29925 /referrer-policy/css-integration/svg/internal-stylesheet.html 29972 /referrer-policy/css-integration/svg/inline-style.html 30211 /referrer-policy/css-integration/svg/external-stylesheet.html 59598 /encoding/legacy-mb-korean/euc-kr/euckr-decode-ksc_5601.html

:jmaher - I'm not sure what to do about this one. Ideas? Or, who could investigate??

I am unable to get runtimes for the tests, in general, I think we should disable the encoding tests, but I wanted to see what the runtimes were on different configs to see if this is osx specific or ccov specific or both. :gbrown, does |./mach test-info| work for you? It didn't for me after a few tries: $ ./mach test-info testing/web-platform/tests/encoding/legacy-mb-korean/euc-kr/euckr-decode-ksc_5601.html ===== testing/web-platform/tests/encoding/legacy-mb-korean/euc-kr/euckr-decode-ksc_5601.html ===== Found testing\web-platform\tests\encoding\legacy-mb-korean\euc-kr\euckr-decode-ksc_5601.html in source control. testing\web-platform\tests\encoding\legacy-mb-korean\euc-kr\euckr-decode-ksc_5601.html not found in any test manifest!

I think test-info is still broken -- :ekyle is working on bug 1500995.

Timeouts recently shifted to chunk 1.

I also tried increasing the chunks to 24, but there was still 1 chunk taking about 2 hours.

Comment on attachment 9023296 [details] [diff] [review] increase max-run-time from 2 hours to 3 hours Review of attachment 9023296 [details] [diff] [review]: ----------------------------------------------------------------- We disabled those encoding tests for the Mac builds because they took too long. I'm OK with increasing the max-run-time, but I would also be OK with disabling them for the time being.

Thanks :marco. I'm looking for a quick win here so I'll go ahead with this patch.
