From 90425a6a50558283a216ba956392426f7e66ced3 Mon Sep 17 00:00:00 2001 From: Jordi Boggiano Date: Fri, 5 Jun 2020 10:36:40 +0200 Subject: [PATCH] Add upgrade note for custom installers --- UPGRADE-2.0.md | 1 + 1 file changed, 1 insertion(+) diff --git a/UPGRADE-2.0.md b/UPGRADE-2.0.md index 33729371a..2b9ccf24a 100644 --- a/UPGRADE-2.0.md +++ b/UPGRADE-2.0.md @@ -17,6 +17,7 @@ - `PluginInterface` added a deactivate (so plugin can stop whatever it is doing) and an uninstall (so the plugin can remove any files it created or do general cleanup) method. - Plugins implementing `EventSubscriberInterface` will be deregistered from the EventDispatcher automatically when being deactivated, nothing to do there. - `Pool` objects are now created via the `RepositorySet` class, you should use that in case you were using the `Pool` class directly. +- Custom installers extending from LibraryInstaller should be aware that in Composer 2 it MAY return PromiseInterface instances when calling parent::install/update/uninstall/installCode/removeCode. See [composer/installers](https://github.com/composer/installers/commit/5006d0c28730ade233a8f42ec31ac68fb1c5c9bb) for an example of how to handle this best. - The `Composer\Installer` class changed quite a bit internally, but the inputs are almost the same: - `setAdditionalInstalledRepository` is now `setAdditionalFixedRepository` - `setUpdateWhitelist` is now `setUpdateAllowList`
