Go 1.10 Beta 2 is released

[Andrew Bonventre]

Hello gophers,

We have just released go1.10beta2, a beta version of Go 1.10.

It is cut from the master branch at the revision tagged go1.10beta2.

There are no known problems or regressions.

Please try running production load tests and your unit tests with the new version.

Your help testing these pre-release versions is invaluable.

Report any problems using the issue tracker:

https://golang.org/issue/new

If you have Go installed already, the easiest way to try go1.10beta2

is by using this tool:

https://godoc.org/golang.org/x/build/version/go1.10beta2

You can download binary and source distributions from the usual place:

https://golang.org/dl/#go1.10beta2

To find out what has changed in Go 1.10, read the draft release notes:

https://beta.golang.org/doc/go1.10

Documentation for Go 1.10 is available at:

Cheers,

The Go Team

Please do test this if you can. There are significant changes to the
go tool. Please report bugs now, so that we can fix them before the
final release.

In particular, there are significant changes to the go tool caching
and `go test`; see the release notes. As a consequence, I encourage
anybody who uses the go tool's -buildmode option to test the new
release, as those options are less used and less tested.

Thanks.

Ian

I apologize for a poor error report, but using 1.10 beta 2  on windows I received an error running 'go test' that I haven't encountered before:

>go test -c

open C:\Users\...\api.test.exe: The process cannot access the file because it is being used by another process. 

It has only occurred once in many (dozens, at least) invocations in the last few days.

Thank you,

Bob

I am running the same version and do not see that errro. Have you modified your ulimit? Does your machine have any sort of antivirus or monitoring software installed?

In any case, I would say you can ignore that error, Go is correctly built by that time.

Make sure to disable anti-virus software. Such software hooks into file operations in order to scan files for viruses and can keep files open longer than you expect. That would be consistent with the error message you're seeing.

This is not limited to anti-virus software but it's most common with it.
