• Git Remote Operations
  • Cloning of git repository.
  • Push operation.
  • Fetch operation.
  • Pull operation.
• APIs
  • Create git repository - POST
  • List all repositories corresponding to a user. - GET
  • List a particular repository corresponding to a user. -GET
  • List all the branches in a repository. - GET
  • List a particular branch in a repository. - GET

Motivation

While setting up our project a few months back, we had to go through the trouble of setup and configuration needed in GitLab. To do away with all of that in future, I decided to create a git server of my own. It will typically help small group of coders, who wish to maintain private repositories within a local network and don't want to do all sorts of setup needed in GitLab and other providers.

Installation

• Install cmake from brew(Mac) or apt-get(linux) package manager. To build from source, follow this link

• Install libgit2 as follows :

    $ wget https://github.com/libgit2/libgit2/archive/v0.23.4.tar.gz
    $ tar xzf v0.23.4.tar.gz
    $ cd libgit2-0.23.4/
    $ cmake .
    $ make
    $ sudo make install
  

• Build the project

  Assuming you have installed a recent version of Go, you can simply run

  go get github.com/gophergala2016/servidor
  

  This will download Servidor to $GOPATH/src/github.com/gophergala2016/servidor. From this directory run go build to create the servidor binary.

• Troubleshooting:-
  ImportError: libgit2.so.0: cannot open shared object file: No such file or directory
  This happens for instance in Ubuntu, the libgit2 library is installed within the /usr/local/lib directory, but the linker does not look for it there. To fix this call

    $ sudo ldconfig
  

Getting started

Start the server by executing servidor binary. By default, servidor will listen to http://localhost:8000 for incoming requests.

Options:

./servidor -h
Usage of ./servidor:
  -R	Set Whether ReceivePack(push operation) will be restricted
  -U	Set Whether UploadPack(clone, pull, fetch operations) will be restricted
  -a	Enable basic authentication for all http operations
  -b string
    	Hostname to be used (default "0.0.0.0")
  -c string
    	Set the path from where the password file is to be read(to be set whenever -a flag is used)
  -g string
    	Mention the gitPath if its different on hosting machine (default "/usr/bin/git")
  -p string
    	Port on which servidor will listen (default "8000")
  -r string
    	Set the path where repositories will be saved, Just mention the base path("repos" directory will be automatically created inside it) (default "/home/administrator/servidor")
  -s	Enable tls connection

Usages:

• Create git repository as follows :

  $ curl -X POST http://<hostname>:<port>/api/repos/create
  -d '{"username":"username1","reponame":"project1"}'
  

  • Typical successful response :

  {
    "response_message": "repository created successfully",
    "clone_url": "http://<hostname>:<port>/username1/project1.git"
  }
  

  • Typical unsuccessful response :

  {
     "response_message": "repository already exists for user",
     "clone_url": "http://<hostname>:<port>/username1/project1.git"
  }
  

• Now, Clone the repository using the clone_url. Do stuffs, push changes set to remote, pull changes from remote etc.

Setup for extra features

• To enable basic authentication, create the password file as follows

  The password file has entries of the format : username:password(in SHA-1 encoded format)

  • To generate the password file, use htpasswd tool. Install it by using

  $ sudo apt-get install apache2-utils
  

  • Once installed you can use

   $ htpasswd -cs path/to/create/password/file/filename username1
  
   $ htpasswd -s path/to/create/password/file/filename username2
  

  Note: while creating sha-1 password for the second user, do not use -c flag. It is used to create the file for the first time. See documentation if needed.

• To enable ssl connection

Generated private key

$ openssl genrsa -out server.key 2048

Generate the certificate

$ openssl req -new -x509 -key server.key -out server.pem -days 3650

Since the certificates are self authorized, server verification must be turned off for clients:

For curl, use -k flag

For git, export GIT_SSL_NO_VERIFY=1

API References

• To display the list of APIs available

  $ curl http://<hostname>:<port>
  

  Response:

  {
    "create_repo_url": "http://<hostname>:<port>/api/repos/create",
    "user_repositories_url": "http://<hostname>:<port>/api/{user-name}/repos",
    "user_repository_url": "http://<hostname>:<port>/api/{user-name}/repos/{repo-name}",
    "branches_url": "http://<hostname>:<port>/api/{user-name}/repos/{repo-name}/branches{/branch-name}"
  }
