Github clone. You can install portable github system into Unix/Linux.

See GitPrep example site. [GitPrep example site](http://perlcodesample.sakura.ne.jp/gitprep/gitprep.cgi/kimoto/gitprep)

![GitPrep Image](gitprep_image.png "Gitprep image example")

## Features

* Github clone: GitPrep has the same interface as GitHub.

* Portable: You can install GitPrep on your own Unix/Linux server.

* Only needs Perl 5.10.1+.

* Smart HTTP support: you can pull and push via HTTP.

* Built-in web server, and reverse proxy support.

* CGI support.

* SSL support.

## A. Run GitPrep by embdded web server

GitPrep has its own web server. You can start GitPrep easily.

### Create gitprep user

Create a **gitprep** user. This is not necessary, but recommended:

    useradd gitprep

    su - gitprep

    cd ~

### Check git command existance

    git --version

## Check Perl Version

Check Perl version. You can use GitPrep if the Perl version is 5.10.1+;

    perl -v

If your don't have Perl 5.10.1+, you need to install newer perl by perlbrew.

    curl -L http://install.perlbrew.pl | bash

    echo "source ~/perl5/perlbrew/etc/bashrc" >> ~/.bash_profile

    source ~/.bash_profile

    perlbrew install perl-5.16.3

    perlbrew switch perl-5.16.3

    perl -v

Download tar.gz archive, expand it and change directory:

    curl -kL https://github.com/yuki-kimoto/gitprep/archive/latest.tar.gz > gitprep-latest.tar.gz

    tar xf gitprep-latest.tar.gz

    mv gitprep-latest gitprep

    cd gitprep

Setup. Needed modules are installed.

    ./setup_module

Check if module setup success . Run the following command.

    prove t

If "syntax OK" is displayed, setup is sucseed.

Setup database.

    ./setup_database

If you used Gitprep version 1 and upgrage it to version 2, you need upgrade database

by the following command.

    # Backup gitprep directory for safety

    cd ..

    cp -rp gitprep gitprep.bak

    # Upgrade database

    cd gitprep

    mv data/gitprep.db data/gitprep_v1bak.db

    ./setup_database

    old/copy_database_v1_to_v2 data/gitprep_v1bak.db data/gitprep.db

If you install git in your local directry,

you must add the correct git command path to the **gitprep.conf** config file.

    [basic]

    ;;; Git command path

    git_bin=/home/yourname/local/bin/git

### Start gitprep server

You can start the application by running the provided gitprep script.

The application is run in the background and the port is **10020** by default.

    ./gitprep

(If you run this command again, gitprep server restart.)

Then access the following URL.

    http://localhost:10020

If you want to change the port, edit gitprep.conf.

If you cannot access this port, you might change the firewall settings.

### Stop gitprep server

You can stop the application by adding the **--stop** option.

    ./gitprep --stop

## B. Run GitPrep as CGI script

You can run GitPrep as CGI script as the following site.

[GitPrep example site](http://perlcodesample.sakura.ne.jp/gitprep/gitprep.cgi/kimoto/gitprep)

This is shared server. I assume you can connect the server via SSH and login your own user.

Installation process is same as above except for create user.

If you finish installation, You can access the following URL.

    http://yourhost/somepath/gitprep/gitprep.cgi

### If you see Internal Server Error

If you see an internal server error, look at the log file (gitprep/log/production.log)

to see what problem has occurred.

## FAQ

## I can't install Gitprep into CentOS

After CentOS 6, some perl core modules are not installed by default.

You can install Perl core modules by the following command.

    yum -y install perl-core

## Can't find git command from GitPrep

If you install git into your local directry,

you must add the correct git command path to the config file **gitprep.conf** .

    [basic]

    ;;; Git command path

    git_bin=/home/yourname/local/bin/git

### blame don't work

In Gitprep, blame page use "git blame --line-porcelain". In old git, there is no --line-porcelain option.

We don't know when --line-porcelain was added to git.

At least, blame page work well in git 1.8.2.1.

### How to upgrade GitPrep

It is very easy. you only overwrite all files except for "gitprep.conf".

If you want to upgrade by "git pull", you can do it.

you create "gitprep.my.conf" copied from "gitprep.my.conf",

and do "git pull"

If you get a rainbow unicorn t-rex error after upgrading, you might be missing

a new CPAN dependency. Run again "setup.sh".

### I can't push large repository by http protocol

There are some reasons.

**1. Git version is old**

If you see "error: RPC failed; result=56, HTTP code = 200" , your git maybe old.

Please upgrade to latest git. I checked git version 1.8.5.5.

**2. GitPrep restriction**

GitPrep restrict max post message size 10MB(This is default of Mojolicious)

You maybe see the following error

    Delta compression using up to 4 threads.

    Compressing objects: 100% (17830/17830), done.

    Writing objects: 100% (18281/18281), 687.05 MiB | 129.92 MiB/s, done.

    Total 18281 (delta 295), reused 18281 (delta 295)

    error: RPC failed; result=22, HTTP code = 413

    fatal: The remote end hung up unexpectedly

    fatal: The remote end hung up unexpectedly

Please increase increase the value of MOJO_MAX_MESSAGE_SIZE

    # 1GB

    export MOJO_MAX_MESSAGE_SIZE=1024000000

**3. git restriction**

git restrict post max size via http protocol.

http.postBuffer value of git config is maybe small.

You maybe see the following error message.

    error: RPC failed; result=56, HTTP code = 200

    fatal: The remote end hung up unexpectedly

    Counting objects: 18281, done.

    Delta compression using up to 4 threads.

    Compressing objects: 100% (17830/17830), done.

    Writing objects: 100% (18281/18281), 687.05 MiB | 133.23 MiB/s, done.

    Total 18281 (delta 295), reused 18281 (delta 295)

    fatal: The remote end hung up unexpectedly

    Everything up-to-date

Please increase the value of http.postBuffer.

    # 1GB

    git config http.postBuffer 1024000000

### How to use reverse proxy?

You can use GitPrep via reverse proxy access

         ----------------------------     ------------

    ---->| Web Server(Reverse proxy)|---->|GitPrep   |

    <----| (Apache, etc)            |<----|          |

         ----------------------------     ------------

I show apache config example.

You can use Name virtual host.

    # HTTP

    <VirtualHost *:80>

      ServerName myhost.com

      <Proxy *>

        Order deny,allow

        Allow from all

      </Proxy>

      ProxyRequests Off

      ProxyPreserveHost On

      ProxyPass / http://localhost:10020/ keepalive=On

      ProxyPassReverse / http://localhost:10020/

      RequestHeader set X-Forwarded-Proto "https"

    </VirtualHost>

If you use GitPrep vis https, you should set X-Forwarded-HTTPS Request Header.

    # HTTPS

    <VirtualHost *:443>

      ServerName myhost.com

      <Proxy *>

        Order deny,allow

        Allow from all

      </Proxy>

      ProxyRequests Off

      ProxyPreserveHost On

      ProxyPass / http://localhost:10020/ keepalive=On

      ProxyPassReverse / http://localhost:10020/

      RequestHeader set X-Forwarded-Proto "https"

    </VirtualHost>

### How to use reverse proxy with sub directory?

GitPrep support reverse proxy with sub directory.

At first, set [reverse_proxy]path_depth option.

    [reverse_proxy]

    ;;; Reverse proxy path depth (default: none)

    ;;; If proxy path is http://somehost.com/foo, you set path_depth to 1.

    ;;; If proxy path is http://somehost.com/foo/bar, you set path_depth to 2.

    path_depth=1

Next you set http server config file. The following is apache example.

    <VirtualHost *:80>

      ServerName perlcodesample.com

      <Proxy *>

        Order deny,allow

        Allow from all

      </Proxy>

      ProxyRequests Off

      ProxyPreserveHost On

      ProxyPass /app1 http://localhost:10020/app1 keepalive=On

      ProxyPassReverse /app1 http://localhost:3000/app1

      ProxyPass /app2 http://localhost:10021/app2 keepalive=On

      ProxyPassReverse /app2 http://localhost:3001/app2

      RequestHeader set X-Forwarded-Proto "https"

    </VirtualHost>

### How to import already existing repositories?

You can import already existing repositories by **script/import_rep** script.

    cd script

    ./import_rep -u kimoto rep_dir

**-u** is user name. rep_dir must contains git respoitories like the following.

    rep_dir/project1.git

           /project2.git

           /project3.git

           /project3.git

If **description** file exists in git repository, it is copied.

### I can't add collabortor more than one

This is GitPrep bug before version 1.5.1.

Please use after version 1.5.2.

If you continue to use GitPrep before version 1.5.1,

collaboration table is broken.

Please fix it by the following way.

    # Run SQLite client

    sqlite3 data/gitprep.db

    # drop collaboration table

    drop table collaboration;

    # Restart

    ./gitprep

### I want to set time zone.

OK. GitPrep suport time zone. You can set time_zone option in conig file.

    [basic]

    ;;; Time Zone

    ;;; GitPrep time zone is GMT by default

    ;;; You can set your local time zone.

    time_zone=+9:00

### How to hide user home directory in ssh repository URL?

**1. Use symbolic link and ssh_rep_url_base option**

At first, set [basic]ssh_rep_url_base option to /git

    ;;; SSH repository url base

    ; For exampke, If you set this value to /git, SSH repository url become

    ; ssh://kimoto@59.106.185.196/git/kimoto/gitprep.git

    ssh_rep_url_base=/git

And you create symbolic link to /home/gitprep/gitprep/data/rep

    cd /

    ln -s /home/gitprep/gitprep/data/rep /git

    chown gitprep:gitprep /git

**2. Use only public key authentication and set [basic]ssh_rep_url_base to empty**

If you use only public key authentication, you can access ssh repository

using the following url.

    ssh://kimoto@59.106.185.196/kimoto/gitprep.git

If you set [basic]ssh_rep_url_base to empty string, this URL is shown on Browser.

    ;;; SSH repository url base

    ; For exampke, If you set this value to /git, SSH repository url become

    ; ssh://kimoto@59.106.185.196/git/kimoto/gitprep.git

    ssh_rep_url_base=

### How to get atom feed of commits page

You can get atom feed of commits page by the following URL

    http://somehost.com/kimoto/gitprep/commits/master.atom

### How to run GitPrep from root user

You can manage the application from the root user.

Start the application

    sudo -u gitprep /home/gitprep/gitprep/gitprep

Stop the application

    sudo -u gitprep /home/gitprep/gitprep/gitprep --stop

If you want to start the application when the OS starts,

add the start application command to **rc.local**(Linux).

If you want to make it easy to manage gitprep,

then create a run script.

    mkdir -p /webapp

    echo '#!/bin/sh' > /webapp/gitprep

    echo 'su - gitprep -c "/home/gitprep/gitprep/gitprep $*"' >> /webapp/gitprep

    chmod 755 /webapp/gitprep

You can start and stop the application with the following command.

    # Start or Restart

    /webapp/gitprep

    # Stop

    /webapp/gitprep --stop

### I want to use GitPrep on Perl 5.8.7 system

GitPrep 2.0 drop support Perl 5.8.7 because latest Mojolicious don't support Perl 5.8.

You can choice two selection.

**1. use GitPrep 1.xx**

GitPrep 1.xx support Perl 5.8.7+. You can use GitPrep v1.12.

https://github.com/yuki-kimoto/gitprep/archive/v1.12.tar.gz

## For Developer

If you are a developer, you can start the application in development mode.

    ./morbo

Then access the following URL.

    http://localhost:3000

If you have git, it is easy to install from git.

    git clone git://github.com/yuki-kimoto/gitprep.git

It is useful to write configuration in ***gitprep.my.conf***, not gitprep.conf.
