runtime/pprof: make TestBlockProfile more robust It's using debug mode of pprof.writeBlock, so the output actually goes through text/tabwriter. It is possible that tabwriter expands each tab into multiple tabs in certain cases. For example, this output has been observed on the new arm64 port: 10073805 1 @ 0x1088ec 0xd1b8c 0xd0628 0xb68c0 0x867f4 # 0x1088ec sync.(*Cond).Wait+0xfc /home/minux/go.git/src/sync/cond.go:63 # 0xd1b8c runtime/pprof_test.blockCond+0x22c /home/minux/go.git/src/runtime/pprof/pprof_test.go:454 # 0xd0628 runtime/pprof_test.TestBlockProfile+0x1b8 /home/minux/go.git/src/runtime/pprof/pprof_test.go:359 # 0xb68c0 testing.tRunner+0x140 /home/minux/go.git/src/testing/testing.go:447 10069965 1 @ 0x14008 0xd1390 0xd0628 0xb68c0 0x867f4 # 0x14008 runtime.chansend1+0x48 /home/minux/go.git/src/runtime/chan.go:76 # 0xd1390 runtime/pprof_test.blockChanSend+0x100 /home/minux/go.git/src/runtime/pprof/pprof_test.go:396 # 0xd0628 runtime/pprof_test.TestBlockProfile+0x1b8 /home/minux/go.git/src/runtime/pprof/pprof_test.go:359 # 0xb68c0 testing.tRunner+0x140 /home/minux/go.git/src/testing/testing.go:447 10069706 1 @ 0x108e0c 0xd193c 0xd0628 0xb68c0 0x867f4 # 0x108e0c sync.(*Mutex).Lock+0x19c /home/minux/go.git/src/sync/mutex.go:67 # 0xd193c runtime/pprof_test.blockMutex+0xbc /home/minux/go.git/src/runtime/pprof/pprof_test.go:441 # 0xd0628 runtime/pprof_test.TestBlockProfile+0x1b8 /home/minux/go.git/src/runtime/pprof/pprof_test.go:359 # 0xb68c0 testing.tRunner+0x140 /home/minux/go.git/src/testing/testing.go:447 Change-Id: I3bef778c5fe01a894cfdc526fdc5fecb873b8ade Signed-off-by: Shenghou Ma <minux@golang.org> Reviewed-on: https://go-review.googlesource.com/5554 Reviewed-by: Dmitry Vyukov <dvyukov@google.com>
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
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.
