#How to Prepare a Development Environment for Tatoeba Using a Pre-made Virtual Machine

## Installing the VM
* Grab the vm file [http://mirrors.bouah.net/pub/tatoeba/Tatovm/](http://mirrors.bouah.net/pub/tatoeba/Tatovm/)

* Untar the file:

   * On Windows: 

        * Download both the vbox and the gz file

        * Use 7zip [http://www.7-zip.org/] to extract Tatovm.vmdk file from the gz file (using the "Extract here" item from the right-click menu)

   * On Linux: use file-roller or from the terminal, type:

   tar -xvf vmfile

* Get and install VirtualBox [https://www.virtualbox.org/wiki/Downloads]

* Load the VM files in VirtualBox:

  From the GUI: **Machine -> Add**, then browse to the location of the .vbox file

  From the command line: VBoxManage registervm /path/to/vm.vbox

## Accessing the VM
* The default http port is 8080 and the default SSH port is 4242.

* On Windows, you may want to download [PuTTY](http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html) as your SSH GUI.

* To SSH into the machine, use the username **tatoeba** and password **tatoeba**:

   ssh -p 4242 tatoeba@127.0.0.1

* Now you can see the website running in your browser by pointing it to the following address:

   127.0.0.1:8080

* Steps such as installing packages require superuser privileges. Prior to such steps, execute:

   su -   

   Type in the password **tatovm** when prompted.

   After performing your operation, execute "exit" to end superuser access.

* The MySQL user is **root** and password is **tatoeba** in case you need to do operations directly on the table or import more data.


##Performing Additional Configuration Steps

These steps will eventually be folded into a new VM, but for now, they must be performed after the VM is installed. 

* Optional: add the following to .bashrc:

    export TERM=xterm-256color

* Log in as superuser (see above) and execute these commands:

    apt-get update

    apt-get install git

    apt-get install php5-curl

    apt-get install bzr *(used with UI translations)*

    apt-get install libpq5  *(used with Sphinx)*

    apt-get install poedit *(used with UI translations)*

    apt-get install flac *(used with audio)*

    apt-get install lame *(used with audio)*

    apt-get install imagemagick *(used for images uploaded to profile)*

    apt-get install php5-imagick *(used for images uploaded to profile)*

* The current VM was assembled shortly before we made the transition from a Subversion repository on Assembla to a Git repository on GitHub, so execute the following steps to update your code from the new repository:

    * Log in as superuser.

    * Rename /var/http/tatoeba to /var/http/tatoeba-bak .

    * Execute this line: 
   chmod 0777 /var/http

    * Log out as superuser (important).
 
    * In the /var/http directory, pull the code from the [GitHub Tatoeba repository](https://github.com/Tatoeba/tatoeba2) as follows:

    git clone https://github.com/Tatoeba/tatoeba2.git /var/http/tatoeba

    * If you will be committing code, configure your user.name and user.email. (You can do this retroactively after your first commit, but it's better to do it beforehand.) For instance, if your username at GitHub is ghuser, and your e-mail address is address@example.com, you'll execute:

        git config --global user.name "ghuser"

        git config --global user.email address@example.com

    * Your new directory /var/http/tatoeba should have the same directory structure as the old /var/http/tatoeba-bak. You can now delete /var/http/tatoeba-bak .

* Execute SQL scripts as follows:

    mysql -u root -ptatoeba tatoeba < /var/http/tatoeba/docs/database/updates/2013-05-31.sql

    mysql -u root -ptatoeba tatoeba < /var/http/tatoeba/docs/database/updates/2013-08-13.sql

    mysql -u root -ptatoeba tatoeba < /var/http/tatoeba/docs/database/scripts/create\_fill\_langStats.sql

* Log into mysql (with "mysql -u root -ptatoeba tatoeba"). Execute the following statement:

    SELECT MAX(id) FROM sentences;

    Based on the return value (for example, 2976558), execute a statement like the following:

    DELETE FROM sentences\_translations WHERE translation\_id > 2976558 OR sentence\_id > 2976558;

    The statement deletes dangling links that point to sentences whose IDs are higher than the maximum that is actually in the database. If you do not execute this statement, the new sentences that you add may match these dangling pointers and end up having incorrect links.

* As superuser, make tmp/cache and its subfolders writable:

   chmod 0777 /var/http/tatoeba/app/tmp/cache/

   chmod 0777 /var/http/tatoeba/app/tmp/cache/*

   chmod 0777 /var/http/tatoeba/app/webroot/img/profiles_36 

   chmod 0777 /var/http/tatoeba/app/webroot/img/profiles_128

* As superuser, restart apache:

   /etc/init.d/apache2 restart
 
* You may find it useful at this point to back up your databases so that you can return them to their virgin state. Make a directory (for instance, /backup ; this may require root permission) and then execute a command such as this one:

    mysqldump -u root -ptatoeba -A > /backup/all_dbs.sql

## Install and Configure Sphinx Search

Follow the instructions under [Installing and Configuring Sphinx Search](install-sphinx).
 
## Customizing Your Installation
* There are three ways to access the codebase via your favorite editor in the comfort of your host computer:

   * Mount a drive over SSH:

       * On Windows: download NetDrive [www.netdrive.net] and use the aforementioned credentials and port

       * On Linux: install SSHFS and then mount it using:

       sshfs tatoeba@127.0.0.1:4242 /path/to/mountpoint

    * Mount a drive over WebDAV:

        * On Windows: use NetDrive. The user and password are **tatoeba**, and the port is 8080.

        * On Linux: use your favorite file manager with WebDAV support, or install cadaver and connect using the above credentials.

    * Mount a shared file (slow and not recommended):

        * Set up Guest additions [https://help.ubuntu.com/community/VirtualBox/GuestAdditions]

        * In the GUI select Devices -> Shared Folders -> Add

        * Browse to the folder you want to share from your host and select it

        * Select the Make permanent option

        * Now mount the shared file on the guest system:

       mount -t vboxfs /media/sharefoldername /path/to/mountpoint

* You can also install a graphical environment (GNOME or any other development environment) to work directly from the VM:

  apt-get install task-gnome-desktop

##Logging Into Tatoeba on the VM

    admin

    corpus_maintainer

* Untar the file:

   * On Windows:

        * Use [7zip](http://www.7-zip.org/) to extract Tatovm.vmdk file from the gz file (using the "Extract here" item from the right-click menu)

   * On Linux: use file-roller or from the terminal, type:
   xz -d Tatovm.vmdk.xz

### Using VirtualBox

* Get and install [VirtualBox](https://www.virtualbox.org/wiki/Downloads)

* Load the VM files in VirtualBox:

  From the GUI: **Machine -> Add**, then browse to the location of the .vbox file

  From the command line: VBoxManage registervm /path/to/vm.vbox

### Using Qemu

* Get and install [qemu](http://en.wikibooks.org/wiki/QEMU/Installing_QEMU)

* Run the following command: (tweak the -m flag for more ram)

  qemu-system-i386 Downloads/Tatovm.vmdk -smp 4 -m 512 -enable-kvm -net nic -net user -redir tcp:8080::80 -redir tcp:4242::22 -redir tcp:8081::81

* Now you can see the website running in your browser by pointing it to the following address:

   127.0.0.1:8080

* Steps such as installing packages require superuser privileges. Prefix these commands with sudo or run:

   sudo su

   Then type in the password **tatoeba** when prompted.

   After performing your operation, execute "exit" to end superuser access.

* The MySQL user is **root** and password is **tatoeba** in case you need to do operations directly on the table or import more data. Getting to a mysql shell or excuting a mysql script is as easy as:

  mysql -u root -ptatoeba tatoeba

  mysql -u root -ptatoeba tatoeba < script.sql

##Performing Additional Configuration Steps

    * If you will be committing code, configure your user.name and user.email. (You can do this retroactively after your first commit, but it's better to do it beforehand.) For instance, if your username at GitHub is ghuser, and your e-mail address is address@example.com, you'll execute:
