Your requirements could not be resolved to an
installable set of packages.

Mecanisum of Composer
1. Gets /packagis.json from repository
○ Ok. It's very fast. Only 1KB.
2. Gets providers information from repository
○ Gets 4 files.
3. Gets package information
○ In case of Symfony Standard
○ 72 files, 7.7MB
○ (If there is file cache in local,
composer fetch data from here.)
4. Resolve Dependencies
5. Gets Package (Archive or Source)

Some ways to resolve it
● Use private repository
○ satis (composer/satis を活用してComposer パッ
ケージの配布を行う http://www.bucyou.net/blog/952)
○ Broker (https://github.com/researchgate/broker)
● Satis is good solution, but we need install
required package in advance.
● Make mirror in Japan.

My Answer
● Better Proxy in Japan

Application
● Name: composer-proxy
● Very Very simple Silex application.
● Features
○ proxy and cache.
● composer-proxy.jp in Sakura-Cloud.

How to use?
● Edit your composer global configuration.
(default $HOME/.composer/config.json)
{
"repositories": [
{ "packagist": false },
{
"type": "composer",
"url": "http://composer-proxy.jp/proxy/packagist"
}
]
}

Speed
● resolve dependencies of symfony/console
● direct to packagist.org
○ 120.24 secouns
● composer-proxy.jp (cached)
○ 41.35 seconds
● 3x faster!!!
● Need more cache information in Japan!!
Please use!!

In furture
● Support notice (for download count) by
asyncronous message queue.
● Support search
● Distribution archive cache
● Add own packages

OMAKE
● vagrant-packagist (https://github.
com/kawahara/vagrant-packagist)
○ You can setup own packagist!
○ 本当は packagist 改造しようと思ったけど、やめた残
骸。PHPer には不慣れな、solr の <del>設定もやってく
れるぞ!! </del>インストールもやってくれるぞ。
