encoding/json: fix decoding of null into Unmarshaler, TextUnmarshaler 1. Define behavior for Unmarshal of JSON null into Unmarshaler and TextUnmarshaler. Specifically, an Unmarshaler will be given the literal null and can decide what to do (because otherwise json.RawMessage is impossible to implement), and a TextUnmarshaler will be skipped over (because there is no text to unmarshal), like most other inappropriate types. Document this in Unmarshal, with a reminder in UnmarshalJSON about handling null. 2. Test all this. 3. Fix the TextUnmarshaler case, which was returning an unmarshalling error, to match the definition. 4. Fix the error that had been used for the TextUnmarshaler, since it was claiming that there was a JSON string when in fact the problem was NOT having a string. 5. Adjust time.Time and big.Int's UnmarshalJSON to ignore null, as is conventional. Fixes #9037.

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
