I can't reproduce your issue.

The runtime tests spawn sub processes to test various aspects of the runtime. Do you have an AV solution or other product that may be interceeding with this ?

[Michael Lekkas]

I have Kaspersky Pure 3.0

The first times I was building, it was asking me to grant access for net and os test packages and I have configured the firewall accordingly.

After that, I am not getting any other warnings from Kaspersky in order to grant access

[Dave Cheney]

Try it without your AV.

[Michael Lekkas]

I have disabled Kaspersky, disabled firewall, even running PowerShell as Administrator but tests are still failing.

Peter, thank you very much for your feedback first of all.

Michael,

How far did you get in the failed package runtime tests? Run go test -v -short from your src\runtime directory. For example,

C:\>gcc --version
gcc (tdm64-1) 4.9.2
 
C:\>go version
go version devel +6cb4033 Wed Dec 31 13:00:03 2014 +0000 windows/amd64

<<SNIP>>
 
=== RUN TestZeroDivisionException

I think the test times out because the machine is slow (or windows is slow,

or the machine is thrashing, ...)

Note this line:

ok      regexp/syntax   7.238s

on my 3-year-old notebook, the same test takes half a second to complete.

and just FYI, the runtime test takes 33s to complete. Taking this time scale

into account, there is no doubt the runtime test will time out on that machine

(it needs at least 7 minutes to complete the runtime test.)

If you do want to complete the test, you can modify run.bat, and raise the

test timeout, by replacing "-timeout=120s" with something like "-timeout=20m"

and then rerun all.bat (or run.bat, if %GOROOT%/bin is in your %PATH%)

[Michael Lekkas]

Minux, you were right about the computer performance.

I had also installed Trusteer Rapport which was causing the issue.

I removed it and now build succeeds.

Thank you very much everyone for your help and Happy New Year!
