composer-patches-plugin

This plugin allows you to provide patches for any package from any package.

If you don't want a patch package outside the root package, consider providing it as package in the repositories key

{
    "name": "vendor/package",
    "type": "project",
    "repositories": [
        {
            "type": "package",
            "package": {
                "type": "metapackage",
                "name": "vendor/package-patches",
                "version": "1.0.0",
                "require": {
                    "netresearch/composer-patches-plugin": "~1.0"
                },
                "extra": {
                    "patches": {
                        "vendor/name": [
                            {
                                "url": "https://my-domain.com/path/to/my.patch"
                            }
                        ]
                    }
                }
            }
        }
    ],
    "require": {
        "vendor/package-patches": "~1.0"
    }
}

See this presentation for the original idea of this plugin: http://de.slideshare.net/christianopitz/distributed-patching-with-composer

Patch properties

Key	Description	Required
url	The url or path to the patch	✓
title	Title to display when applying or reverting the patch
args	string, which will be added to the patch command
sha1	SHA1 checksum of the patch contents for security check - when given the patches actual checksum and this value are compared and if they don't match an exception will be thrown

You may provide patches per package and optionally by version constraints:

Provide patches by package only

{
    "name": "netresearch/typo3-patches",
    "version": "1.0.0",
    "type": "metapackage",
    "require": {
        "netresearch/composer-patches-plugin": "~1.0"
    },
    "extra": {
        "patches": {
            "typo3/cms": [
                {
                    "title": "[FEATURE] Allow registration of different login forms",
                    "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/32f331fead9c7aa50d9248c54e3c0af75d793539"
                },
                {
                    "title": "[PATCH] [BUGFIX] Flexform \"required\" on input fields applies to last field only",
                    "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/a48f8b0dae11ce7246eff43132d986bccf55b786"
                }
            ]
        }
    }
}

Provide patches by package and versions or version constraints

composer.json:

{
    "name": "netresearch/typo3-patches",
    "version": "1.0.0",
    "type": "metapackage",
    "require": {
        "netresearch/composer-patches-plugin": "~1.0"
    },
    "extra": {
        "patches": {
            "typo3/cms":     {
                "6.2.0-beta1": [
                    {
                        "title": "[FEATURE] Allow registration of different login forms",
                        "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/32f331fead9c7aa50d9248c54e3c0af75d793539"
                    },
                    {
                        "title": "[PATCH] [BUGFIX] Flexform \"required\" on input fields applies to last field only",
                        "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/a48f8b0dae11ce7246eff43132d986bccf55b786"
                    }
                ],
                "6.2.0-beta2": [
                    {
                        "title": "[PATCH] [BUGFIX] Flexform \"required\" on input fields applies to last field only",
                        "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/a48f8b0dae11ce7246eff43132d986bccf55b786"
                    }
                ],
                "6.2.*": [
                    {
                        "title": "[BUGFIX] Ignore dependencies on non typo3-cms-extension",
                        "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/9fe856ac96e6a53fef8277f36a4a80bace6f0ae9",
                        "sha1": "b56a1c47a67d1596c0bd8270e61c44f8911af425"
                    }
                ]
            }
        }
    }
}

Note: When multiple version constraints match the version of the target package, all of the matching patches will be applied (canonicalized by theyr checksums, so no duplicates should occure).

Provide patches from URLs or paths

You can put any part of the patches object into another JSON and load it via an URL (or a path):

composer.json:

{
    "name": "netresearch/typo3-patches",
    "version": "1.0.0",
    "type": "metapackage",
    "require": {
        "netresearch/composer-patches-plugin": "~1.0"
    },
    "extra": {
        "patches": {
            "typo3/cms": "http://example.com/typo3-patches.json"
        }
    }
}

http://example.com/typo3-patches.json

{
    "6.2.0-beta1": [
        {
            "title": "[FEATURE] Allow registration of different login forms",
            "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/32f331fead9c7aa50d9248c54e3c0af75d793539"
        },
        {
            "title": "[PATCH] [BUGFIX] Flexform \"required\" on input fields applies to last field only",
            "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/a48f8b0dae11ce7246eff43132d986bccf55b786"
        }
    ],
    "6.2.0-beta2": [
        {
            "title": "[PATCH] [BUGFIX] Flexform \"required\" on input fields applies to last field only",
            "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/a48f8b0dae11ce7246eff43132d986bccf55b786"
        }
    ],
    "6.2.*": [
        {
            "title": "[BUGFIX] Ignore dependencies on non typo3-cms-extension",
            "url": "https://git.typo3.org/Packages/TYPO3.CMS.git/patch/9fe856ac96e6a53fef8277f36a4a80bace6f0ae9",
            "sha1": "b56a1c47a67d1596c0bd8270e61c44f8911af425"
        }
    ]
}

Provide patches from local stored files

You can use absolute paths or paths relative to the application root.

composer.json:

"repositories": [
        {
            "type": "package",
            "package": {
                "type": "metapackage",
                "name": "vendor/package-patches",
                "version": "1.0.0",
                "require": {
                    "netresearch/composer-patches-plugin": "~1.0"
                },
                "extra": {
                    "patches": {
                        "typo3/cms":     [
                            {
                                    "title": "[FEATURE] Allow registration of different login forms",
                                    "url": "patches/example_local_file.patch"
                            }
                        ]
                    }
                }
            }
        }
    ],
   "require": {
        ....
    },

I have also added a new folder at the same level as the composer.json called "patches" and add a patch file example_local_file.patch like:

# This patch file was generated by NetBeans IDE
# It uses platform neutral UTF-8 encoding and \n newlines.
--- a/src/com/zoho/crm/library/exception/Logger.php
+++ b/src/com/zoho/crm/library/exception/Logger.php
@@ -6,7 +6,7 @@
 	{
 		set_include_path(ZCRMConfigUtil::getConfigValue('applicationLogFilePath'));
 		$path=get_include_path();
-		if($path{strlen($path)-1}!='\/')
+		if($path[strlen($path)-1]!='\/')
 		{
 			$path=$path."/";
 		}

Note that the patch will be called with the option -p1 (remove the first slash) and in the directory of the library.

Then run the commands to update the dependency and to install patches:

composer update vendor/package-patches
composer install

Requiring the patches:

just require the package with the patches.
