go - 从源代码构建 Go 时测试失败

Question

当我从源代码构建 Golang 时，我无法通过构建测试:

hg clone -u release https://code.google.com/p/go
cd go/src
./all.bash

....
ok      net/url 0.005s
ok      os  0.595s
--- FAIL: TestExtraFiles (0.12 seconds)
exec_test.go:230: TestExtraFiles: Something already leaked - closed fd 3
exec_test.go:403: Run: exit status 1; stdout "leaked parent file. fd = 10; want 9\n", stderr ""
FAIL
FAIL    os/exec 0.822s
ok      os/signal   0.511s

请帮忙。这是在我的 webfaction 共享机器上。

根据 issue 3001，这是 CentOS 5/RHEL 5 中的错误, 基本上内核会忽略 O_CLOEXEC。

因此，要么忽略错误(坏主意)，要么转移到更新的 Linux 版本。
