Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

ageyev

/*
This smartcontract is used to store documents text on the Ethereum blockchain
and to get the document by document's hash (sha256).

*/

contract ProofOfExistence{

    /* ---- Public variables: */
    string public created;

ageyev

/*
Usage:

1. Account owner sends a request for verification, in this request he sends a fingerprint of his OpenPGP key stored on cryptonomica.net
2. This contracts sends back a string to sign
3. Accont owener signs this strign with his OpenPGP key and sends back to smartcontract.
4. Information about verification is public visible - who needs to check can download verified public key from cryptonomica.net and check if owner of stated Ehereum acconts is also known owner of verified OpenPGP key on cryptonomica.net

It's also possible to create a web-inerface using Cryptonomica's API like:
