SIGHASH_NOINPUT and Lightning Network

[Frodek]

1.
Here is SIGHASH_NOINPUT: https://github.com/Roasbeef/bitcoin/commit/4b3c3f1baf7985208ceb6887261ee150ab6e3328

Code:

    const bool fAnyoneCanPay;  //! whether the hashtype has the SIGHASH_ANYONECANPAY flag set
    const bool fNoInput;       //! whether the hashtype has the SIGHASH_NOINPUT flag set
    const bool fHashSingle;    //! whether the hashtype is SIGHASH_SINGLE

But I can't find "SIGHASH_NOINPUT" in bitcoin master source.
This is only in branch?

2.In Bitcoin blockchain are transactions which opens bidirectional LN channel?
If not, these are in testnet?

3.I want search blocks are find all transactions which opens bidirectional LN channel.
How I can do it?

It doesn't it exist in Bitcoin yet. SIGHASH_NOINPUT requires a soft fork.

This question doesn't make any sense.

You can't. Lightning Network funding transactions look identical to any other transaction paying to a P2WSH output.
