# In general, updating MISP between point releases (for exampe 2.4.50 -> 2.4.53) happens with one of the following two options (both are to be executed as root):

# Option 1: To update to the latest commit from the 2.4 branch simply pull the latest commit
cd /var/www/MISP
git pull origin 2.4
git submodule update --init --force

# Option 2: If you want to stick to a point release instead of pulling the latest commit directly:
cd /var/www/MISP
git fetch
git checkout tags/$(git describe --tags `git rev-list --tags --max-count=1`)
git submodule update --init --force

# If you would like to upgrade from a minor version to another, look at the UPGRADE.txt file instead (such as 2.3.142 -> 2.4.13)

# If for any reason something goes wrong with the above instructions, walk through the following manual upgrade

# 1. Update the MISP code to the latest hotfix.
As user root, do the following:

cd /var/www/MISP
git fetch
git checkout tags/$(git describe --tags `git rev-list --tags --max-count=1`)
# if the last shortcut doesn't work, specify the latest version manually
# example: git checkout tags/v2.4.XY
# the message regarding a "detached HEAD state" is expected behaviour
# (you only have to create a new branch, if you want to change stuff and do a pull request for example)


# 2. Update CakePHP to the latest supported version (if for some reason it doesn't get updated automatically with git submodule)

cd /var/www/MISP
git submodule update --init --force


# 3. Update Mitre's STIX and its dependencies

cd /var/www/MISP/app/files/scripts/
rm -rf python-cybox
rm -rf python-stix
sudo -u www-data git clone https://github.com/CybOXProject/python-cybox.git
sudo -u www-data git clone https://github.com/STIXProject/python-stix.git
cd /var/www/MISP/app/files/scripts/python-cybox 
sudo -u www-data git checkout v2.1.0.12
python setup.py install 
cd /var/www/MISP/app/files/scripts/python-stix 
sudo -u www-data git checkout v1.1.1.4
python setup.py install


# 4. Update mixbox to accomodate the new STIX dependencies:
cd /var/www/MISP/app/files/scripts/
rm -rf mixbox
sudo -u www-data git clone https://github.com/CybOXProject/mixbox.git
cd /var/www/MISP/app/files/scripts/mixbox
sudo -u www-data git checkout v1.0.2
python setup.py install


# 5. Update CakeResque and its dependencies

cd /var/www/MISP/app

# Edit composer.json so that cake-resque is allowed to be updated
# "kamisama/cake-resque": ">=4.1.2"

vim composer.json
php composer.phar self-update
# if behind a proxy use HTTP_PROXY="http://yourproxy:port" php composer.phar self-update
php composer.phar update


# To use the scheduler worker for scheduled tasks, do the following:
cp -fa /var/www/MISP/INSTALL/setup/config.php /var/www/MISP/app/Plugin/CakeResque/Config/config.php


# 6. Make sure all file permissions are set correctly

find /var/www/MISP -type d -exec chmod g=rx {} \;
chmod -R g+r,o= /var/www/MISP/
chown -R www-data:www-data /var/www/MISP/


# 7. Restart the CakeResque workers

su - www-data -s /bin/bash -c 'bash /var/www/MISP/app/Console/worker/start.sh'

# You can also do this using the MISP application by navigating to the workers tab in the server settings and clicking on the "Restart all workers" button.


# 8. Add any new dependencies that might have been added since you've last updated (shown below)

# 8.a requirements for the pubsub optional feature
pip install pyzmq
