Packagist and Github mirroring

Experiencing Github issues ? You want a local cache to speed up tests and deployment ?

Mirroring Packagist

Set up a new host on your webserver : packagist.mycompany.com
Go to the document root for the new host
run git clone git://github.com/ekino/php-mirroring.git .
run cp config.php.sample config.php
edit rules: vim config.php
run php mirror.php - this can take a while for the first one

add a new cron job sudo crontab -u www-data -e:

 0 */1 * * * cd /PATH_TO_DOCUMENT_ROOT && php mirror.php

Mirroring Github

Create a new mirror directory
```
 mkdir mirrors/github.com
```

Add new mirror

 cd mirrors/github.com
 git clone --mirror git://github.com/ekino/php-mirroring.git ekino/php-mirroring.git

Of course you need to repeat this operation for each mirror.

Setup a cron to update the mirror:

 0 */1 * * * /git/repositories/mirrors/update-mirrors.sh

Add the file : vim /git/repositories/mirrors/update-mirrors.sh

 #!/bin/sh
 cd /git/repositories/mirrors/github.com

 for i in */*.git; do
   cd $i

   url=`echo $i | sed "s/.git//"`

   echo "   > check 404 on https://github.com/${url}"
   curl -ILs https://github.com/${url} | head -n 1 | grep "HTTP/1.1 200 OK" > /dev/null

   if [ $? -eq 0 ] ; then
       echo "   > fetching git changes"
       git fetch
   fi

   #echo "end ..."
   cd ../..
 done

Usages

Using source mode with gitolite

Setup a Gitolite
Add a new entry
```
 repo mirrors/..*
     R = @team
```

set the source mode to true

 function include_source() 
 {
     return true;
 }

Using dist mode with a http server

setup a new php instance with a dedicated vhost

make sure the replace_dist_host function point to the correct vhost

 function replace_dist_host(array $metadata)
 {
     list($vendor, $name) = explode("/", $metadata['name']);

     if (!preg_match('@(https://api.github.com/repos/|https://github.com/|https://bitbucket.org)([a-zA-Z0-9_\-\.]*)/([a-zA-Z0-9_\-\.]*)/(zipball|archive|get)/([a-zA-Z0-9\.\-]*)(|.zip)@', $metadata['dist']['url'], $matches)) {
         return '';
     }

     $host = sprintf('http://packagist.mycompany.com/cache.php/github.com/%s/%s/%s.zip',
         $matches[2],
         $matches[3],
         $metadata['dist']['reference']
     );

     return $host;
 }

 function include_dist() 
 {
     return true;
 }

 function include_source() 
 {
     return true; // set to false if you only want to expose distribution
 }

Composer.json

Make sure you have a clean project
```
 rm -rf composer.lock vendor
```

update the composer.json file to disable packagist and add the new one

 {
     "repositories":[
         { "packagist": false },
         { "type": "composer", "url": "http://packagist.mycompany.com"}
     ],
     
     // ...
 }

If you are using non-composer packages, use the correct source url when adding them.

    {
        "repositories":[
            {
                "type": "package",
                "package": {
                    "name": "documentcloud/underscore",
                    "version": "dev-master",
                    "source": {
                        "url": "git@git.mycompany.com:/mirrors/github.com/documentcloud/underscore.git",
                        "type": "git",
                        "reference": "master"
                    }
                }
            }
            
            // ...
        ],
        
        // ...
    }

Install the dependencies
```
 php composer.phar install
```
