[go-nuts] Re: [security] Go 1.7.4 and Go 1.6.4 are released

I find it unfortunate that the fix for #17276 "time: TestLoadFixed failure" has not been included in go1.7.4. So tests in all.bash (to buiild from source) will fail on a fully patched Ubuntu 14.04 LTS. I expect go tool dist test to fail on all Linux

I just had a fairly strange not reproducible panic. I have no idea whether this could be a go bug or if the C library I am using is buggy. In case it looks like a go bug I should probably post this on the issue tracker. Does anyone have an idea whether this is useful or if I should just forget

Quick update: go1.7.4 was tagged with the wrong commit. It has been updated from: go1.7.4 0ad8bf4122de7396f771ed12f86934ea3177d6cf to go1.7.4 6b36535cf382bce845dd2d272276e7ba350b0c6b If you built from the go1.7.4 tag at 0ad8b, the version will be incorrectly reported as "go1.7.3". The binaries

Two security-related issues were recently reported, and to address these issues we have just released Go 1.6.4 and Go 1.7.4. We recommend that all users update to one of these releases (if you're not sure which, choose Go 1.7.4). The issues addressed by these releases are: On Darwin, user's

Conn.Read is a much higher level construct the using the syscalls directly. The largest part of the overhead is coordinating with the network poller. There's also a slight overhead of using the net.Conn interface, so asserting the value to a *net.TCPConn may save you a little (though I'm not

Generally, the answer is, don't use regular expressions. This is good advice in any language and for almost any problem. In this specific case, if you care about speed, write some more specific code that does what you need instead of falling back on regular expressions. On Wednesday,
