Currently we run profiling tests for around 200ms in short mode. However, even on platforms with good profiling, these tests are inherently flaky, especially on loaded systems like the builders. To mitigate this, modify the profiling test harness so that if a test fails in a way that could indicate there just weren't enough samples, it retries with a longer duration. This requires some adjustment to the profile checker to distinguish "fatal" and "retryable" errors. In particular, we no longer consider it a fatal error to get a profile with zero samples (which we previously treated as a parse error). We replace this with a retryable check that the total number of samples is reasonable. Fixes #13943. Fixes #13871. Fixes #13223.

The Go Programming Language
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.
Our canonical Git repository is located at https://go.googlesource.com/go. There is a mirror of the repository at https://github.com/golang/go.
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
Note that we do not accept pull requests and that we use the issue tracker for bug reports and proposals only. Please ask questions on https://forum.golangbridge.org or https://groups.google.com/forum/#!forum/golang-nuts.

Binary Distribution Notes
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.
