### RSS
|
|
|
|
|
|
|
|
|
|
mvp will support rss. with full post contents
|
|
|
|
|
|
|
|
|
|
## Cache
|
|
|
|
|
|
|
|
|
|
/cache/actors/ stores actor objects fetched from remote instances
|
|
|
|
|
filename: <sha256 of actor id>.json, contents: the full activitypub json for the actor
|
|
|
|
|
inotify will be used to detect completion of a queued request
|
|
|
|
|
if a remote request fails after a reasonable retry interval, it may be aborted and the cache may
|
|
|
|
|
be filled in with dummy data indicating the resource could not be fetched
|
|
|
|
|
|
|
|
|
|
## Task queue
|
|
|
|
|
|
|
|
|
|
stores queued outgoing requests
|
|
|
|
|
TODO

|
|
## Procedures
|
|
|
|
|
|
|
|
|
|
- compile: takes everything in src and db (and cache) and regenerates the contents of public
|
|
|
|
|
compile may make queued requests and block until they are complete
|
|
|
|
|
compile should be smart and only regenerate resources as necessary, based on file
|
|
|
|
|
timestamps
|
|
|
|
|
if new posts are present, compile must generate output products for the new posts,
|
|
|
|
|
queue all activitypub outgoing requests, and then save the completion flag
|
|
|
|
|
if a new post is present, the output product is also present, but the completion flag is
|
|
|
|
|
not present, re-queue all outgoing requests then save the completion flag
|
|
|
|
|
if an output product for a post is present, the completion flag is present, but the
|
|
|
|
|
original post is not present, queue undo requests and then remove the output and flag
|
|
|
|
|
- accept follow: fetch remote user, make all reasonable security checks, and accept follow request.
|
|
|
|
|
store result in /cache/actors/ and /db/followers/. then call a compile
|
|
|
|
|
- accept comment: fetch remote user, make all reasonable security checks, and save comment. store
|
|
|
|
|
result in /cache/actors/ and /db/comments/. then call a compile
|
|
|
|
|
|
|
|
|
|
## Followers/following lists
|
|
|
|
|
|
|
|
|
|
directory-based (/db/followers/)
|
|
|
|
|
each file is a follower, filename is <sha256 of actor id>.json, file contents is the
|
|
|
|
|
follow object received. corresponding cache entry for the remote actor
|
|
|
|
|
|
|
|
|
|
initially we can accept all follows. later a mechanism can be added for manual approval
|
|
|
|
|
|
|
|
|
|
## Comments

|
|
|
|
|
|
|
