[release-branch.go1.6] crypto/x509: read Darwin trust settings for root CAs Darwin separately stores bits indicating whether a root certificate should be trusted; this changes Go to read and use those when initializing SystemCertPool. Unfortunately, the trust API is very slow. To avoid a delay of up to 0.5s in initializing the system cert pool, we assume that the trust settings found in kSecTrustSettingsDomainSystem will always indicate trust. (That is, all root certs Apple distributes are trusted.) This is not guaranteed by the API but is true in practice. In the non-cgo codepath, we do not have that benefit, so we must check the trust status of every certificate. This causes about 0.5s of delay in initializing the SystemCertPool. On OS X 10.11 and older, the "security" command requires a certificate to be provided in a file and not on stdin, so the non-cgo codepath creates temporary files for each certificate, further slowing initialization. Updates #18141.

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software.
For documentation about how to install and use Go, visit https://golang.org/ or load doc/install-source.html in your web browser.
Go is the work of hundreds of contributors. We appreciate your help!
To contribute, please read the contribution guidelines: https://golang.org/doc/contribute.html
Unless otherwise noted, the Go source files are distributed under the BSD-style license found in the LICENSE file.
If you have just untarred a binary Go distribution, you need to set the environment variable $GOROOT to the full path of the go directory (the one containing this file). You can omit the variable if you unpack it into /usr/local/go, or if you rebuild from sources by running all.bash (see doc/install-source.html). You should also add the Go binary directory $GOROOT/bin to your shell's path.
For example, if you extracted the tar file into $HOME/go, you might put the following in your .profile:
export GOROOT=$HOME/go export PATH=$PATH:$GOROOT/bin
See https://golang.org/doc/install or doc/install.html for more details.
