The Go programming language
c3b5db895b
In Go 1.3 the runtime called panicstring to report errors like divide by zero or memory faults. Now we call panic (gopanic) with pre-allocated error values. That new path is missing the checking that panicstring did, so add it there. The only call to panicstring left is in cnew, which is problematic because if it fails, probably the heap is corrupt. In that case, calling panicstring creates a new errorCString (no allocation there), but then panic tries to print it, invoking errorCString.Error, which does a string concatenation (allocating), which then dies. Replace that one panicstring with a throw: cnew is for allocating runtime data structures and should never ask for an inappropriate amount of memory. With panicstring gone, delete newErrorCString, errorCString. While we're here, delete newErrorString, not called by anyone. (It can't be: that would be C code calling Go code that might block or grow the stack.) Found while debugging a malloc corruption. This resulted in 'panic during panic' instead of a more useful message. LGTM=khr R=khr CC=golang-codereviews https://golang.org/cl/138290045 |

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 README). 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.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 doc/install.html for more details.
