math/rand: test times out on arm when using soft float emulation #3740
Labels
Comments
Currently ./run.bash runs all the tests with 120 second timeout, running on my netgear stora, it just gets in under the wire at 117 seconds. This machine claims to have a 1Ghz processor, so I can easily envisage that the math/rand tests run overtime on the Pi. % go test math/rand -test.short -test.v === RUN TestStandardNormalValues --- PASS: TestStandardNormalValues (14.70 seconds) === RUN TestNonStandardNormalValues --- PASS: TestNonStandardNormalValues (58.81 seconds) === RUN TestStandardExponentialValues --- PASS: TestStandardExponentialValues (14.73 seconds) === RUN TestNonStandardExponentialValues --- PASS: TestNonStandardExponentialValues (29.50 seconds) === RUN TestNormTables --- PASS: TestNormTables (0.05 seconds) === RUN TestExpTables --- PASS: TestExpTables (0.08 seconds) PASS ok math/rand 117.952s |
With latest src from tip, the test error is now from encoding/gob.

Hmm, can you please make sure GOARM=5 is set when testing GOARM=5 go test math/rand -test.short -test.v If GOARM is not set, the linker will not insert the soft float instructions, so you get the floating point version. On my ~1ghz netgear stora (ARMv5) the math/rand test completes in 117s, so just gets in under the wire. I read the Pi is 700Mhz or so so it's reasonable to assume the test just doesn't complete in time. |

Issue #3728 has been merged into this issue. |
Could you please try this patch http://golang.org/cl/6304087 Which increases the test timeout by 50% if you use soft float. |
