minor fixes for testing-file

initial rough support for sending follow to CN
we now send follows to CN to the api/profile/profileName/fedfollow endpoint, either with a post, or a delete. - commit also contains files where line-endings suddenly changed to crlf (now it's back to lf). - targetRequestType (post/delete) now depends on the activity - we now also set the id to username when fetching a user from CN

Yannis Vogel	ba88adcebd	refactored ContentNation data-format - also fixed issue where we didn't retrieve posts from the DB - also fixed issue where posts from db were malformatted - changed contentnation data-converter for comments & votes to support the new data-structure (more consistent, easier to read)	2025-05-21 20:06:43 +02:00

Yannis Vogel	767f51cc5b	queue-redis connection + fqdn->CN follow-support - the resque queue integration is now connected to our redis instance. - IMPORTANT NOTICE: In order for this to work, we needed to change the plugins file under vendor/resque/php-resque/lib/Resque/Redis.php #137 ($this->driver->auth($password, $user); (this change is neccessary for our implementation, as they normally don't support the $user attribute as it would be upstream breaking change). I might create a fork for this, to which we bind with composer - The inboxJob now inherits from api instead of creating its own api instance - inbox now actually works with follows and Undo-follows from mastodon->CN (adding the follower to our followers-db and removing it on undo). - fixed bug where paths for templates was incorrectly adjusted - better/proper support for comment-activity in getExternalPosts	2025-05-18 08:51:18 +02:00

Yannis Vogel	ce7aa5c72d	remove debug/todos for live tests	2025-04-30 22:49:20 +02:00
Yannis Vogel	8ea9bdcf9a	major structure rework - checkSignature for our fqdn now happens in the connector - cache public key for 1 hour - change author on some files - refactored outbox to api/v1/newcontent (CN->Federator communicates to here) - disabled post for outbox (as that should go to v1/newcontent) - initial support for receiving votes from CN, not fully working/clean yet	2025-04-30 22:44:50 +02:00

Yannis Vogel	352377887c	added proper application-signing - we now check whether the request was sent from contentnation and approve the request with contentnations pub key - fix issue where inbox wasn't gotten as it also got a username - rough initial draft of parsing of connector-specific data (plugins/federator/contentnation::jsonToActivity) - added key paths and headername to config	2025-04-23 21:07:26 +02:00
Yannis Vogel	0edc4c0db6	remove mastodon.ini	2025-04-23 14:02:54 +02:00
Yannis Vogel	21f73fb56f	cleanup and removal of mastodon-integration - In-&Outbox now use factories to convert data - initial creation of followers-data (wip, not working) - fixed some issue where connector would always fail (as we deliberately always pass username@domain and the regex there always fails) - deleted all mastodon-files (mastodon.ini and mastodon plugin) - minor fix where toObject of create would override id with an empty string if no url is set	2025-04-23 14:02:20 +02:00
Yannis Vogel	4d36fc3c61	fix remaining phan errors - also cleaned up dummy - added new rewrite for apache for sharedInbox (your.fqdn/inbox) - fixed json-formatting of publicKey when requesting user via api	2025-04-22 14:30:26 +02:00

Yannis Vogel	f6d6c74bc6	minor logging cleanup	2025-04-17 12:38:45 +02:00
Yannis Vogel	20c2db4b35	support outbox post - we can now receive content into outbox (f.e. from contentnation) and post it into the outbox-user-logfile for now - we now verify post-requests according to ActivityPub standard - minor bugfix where user specified by passed user-parameter is possibly not included in postForUser-call	2025-04-17 12:13:34 +02:00
Yannis Vogel	305ded4986	WIP inbox-support - includes hacky following-mechanic in order to simulate a follow on mastodon (not properly working, need to also inject the user this creates into the followers db for the target mastodon-user) - created endpoint for inbox. SharedInbox is used when no user is provided (/api/federator/fedusers/inbox'), the regular inbox link now works (/users/username/inbox). - Retrieve all followers of sender and, if they're part of our system, send the activity into their personal inbox - Support Announce and Undo Activity-Types - Inbox currently converts to proper ActPub-objects and saves data to log-files	2025-04-15 16:42:46 +02:00

Yannis Vogel	1a7b8264a1	fixes for outbox - mastodon now properly sets available type-attributes - database should now save user with his platform (as that's the actual unique identifier, plain username isn't) - properly retrieve items from mastodon and print them on api-call (example call for mastodon: federator/fedusers/gutenberg_org@mastodon.social/outbox?page=0)	2025-04-09 12:52:27 +02:00
Yannis Vogel	530caa7ea6	initial mastodon support and minor improvements - reworked plugin handling. Main now registers and keeps all connectors and based on request we select the correct one and pass it (mainly for clean async-request-handling) - added outbox functionality for mastodon - changed image-mime-type approach to retrieve mime-type from the url, this way we don't need to store the images on our server/download each image - added host for connector for better debugging - minor bug-fixes	2025-04-08 22:03:19 +02:00
