Got this mainly from my patches to FreeSocial. The idea is to migrate
also the Note activity to a plugin and have everything be handled as
events, only filling out the basic "context" stuff in the Notice class.
Getting rid of NoticeListItemAdapter, putting more into ActivityHandlerPlugin
and relying on plugins to handle rendering code of the content. This gives us
a lot more structure and consistency in notice structure and allows activity
plugins to stop rendering certain kinds of notices more easily.
There should also be a property for an ActivityHandlerPlugin class to avoid
rendering notices in the ordinary stream, so we don't have to overload stuff.
Lost dependency of OStatus plugin for lib/microappplugin.php, whoo!
also noting which plugins should be upgraded to new saveActivity support.
Favorite plugin won't work with the new system just yet, it doesn't have
the necessary functions to extract activity objects, but that's coming
in the next (few) commits.
saveActivity will accept an Activity which gets parsed and saved through
plugins. So when an ActivityHandlerPlugin (such as Favorite will be soon)
gets a feed to save, this will be the function called instead of saveNew.
The code is now more event-driven when it comes to rendering notices
and their related HTML elements, since we can't have direct calls from
core to a plugin.
lib/activitymover.php has a function to move a Favorite activity which
will not happen now. The move must be pluginified and performed as an
event which plugins can catch on to.
Now we have to fix any code in the core which directly uses the Fave class
or any other favorite stuff, since it is pluginised and thus might not be
available on some installations.
It's less of a problem that one queue-item does not get handled, attention wise,
than that the queue keeps filling up. The typical error raised here is 'already exists'
so it's not even the case that the item won't get handled (it already has been).
The real problem is that the queue_item table accepts duplicates (content-wise) which it
should not.
No validation has been attempted yet. Lots of changes left. This
is visibly not (very) different from the previous CSS layout. But
some simplifications have been made.
Might cause issues with local changes to themes and CSS. Also maybe
javascript which depends on certain legacy microformats elements.
The move to microformats2 is motivated by the announcement that all
microformats should be migrated to version 2, as of 2014-06-20 at:
http://microformats.org/2014/06/20/microformats-org-turns-9-upgrade-to-microformats2
This also fixes a problem with "initial salmon slap", which was a
problem for newly registered accounts which would have their first
salmon slap fail to distribute since there was a problem with Magicsig
keys. Apparently we have to re-read them with importKeys so the
Crypt_RSA objects publicKey and privateKey match later instances of them.
I think it may have been that generate() doesn't specify a signatureMode,
but I leave experimentation of that to the future.
We don't run a service similar to update.status.net yet. Maybe we should,
but that's for the future to decide. Currently I view it as a callback
that we want to avoid.
htmLawed cleans stuff out properly, but there's no very good way right
now to show text/html attachments, since everything gets jumbled up with
our own CSS etc. Best would be an iframe or just a new tab or so.
Conversation trees works pretty bad with the current layout, javascript
etc. So it's best if we separate it and work on it as a side-project. The
oldschool settings are currently being deprecated (or broken out like this).
I'll wait with removing User preferences for oldschool conversation tree,
since that might be reusable data. But I guess it will go in the near future.
Make the logic match the intent described in the comments.
The intent is clearly "accept notices whenever (A or B or C)", but
the logic implemented was more like "not ((not A) or (not B) or (not C))",
which is a basical boolean algebra fail (each of those ORs need to
become ANDs for double-negation to work).
The practical implication was that, for example, writing a reply
to someone else's notice and including an @-reference to _another_
user on another site to bring them into the discussion would
fail to deliver the notice to the new user because their server
would basically say `oh no, you can't message this user
from someone else's thread' because an earlier check for
the `A' or `C' parts of `(A or B or C)' prevents `B' from
being checked.
cf.: <http://status.hackerposse.com/notice/55846>, which was
refused by the nhcrossing.com server because it didn't know
about <http://sn.jonkman.ca/notice/93724>, even though it would
have passed the later `notice contains a reference to a local user'
check if not for an exception being prematurely thrown.
The whole idea of reporting `which specific check FAILED'
in an `if ANY SUCCEEDS' analysis is just bogus, so nix all of
the distinct ClientExceptions--a single `ALL FAILED' exception
is the only one that makes sense.

Also, tooltip text on time representation for humans has been improved.
Unfortunately no standardised representation (like "RFC850") had 4-digit years.
The File object now stores width and height of files that can
supply this kind of information. Formats which we can not read
natively in PHP do not currently benefit from this. However an
event hook will be introduced later.
The CreateFileImageThumbnail event is renamed to:
CreateFileImageThumbnailSource to clarify that the hooks should not
generate their own thumbnails but only the source image. Also it now
accepts File objects, not MediaFile objects.
The thumbnail generation is documented in the source code. For
developers, call 'getThumbnail' on a File object and hope for the best.
Default thumbnail sizes have increased to be more appealing.
The exception thrown from MediaFile will be caught and simply result in
no thumbnail at all right now. In the future we might use a catch-all
and have a "cannot generate preview"-icon or something.
VideoThumbnails requires php5-ffmpeg and php5-gd.
Added the following FIXME:
How should a Twitter user get their Inbox filled with foreign tweets?
Every imported Twitter user has a profile in the Profile table, so we
could setup a Subscription entry for each of those, meaning they get
collected in the InboxNoticeStream... But this would mean a lot of
unnecessary entries and listings that generally just point to the
locked down Twitter service.
Let's figure out a good relation so we can connect any profile to any
imported foreign notice, so it shows up in the "all" feed.
Also cleaned up and made typing stricter for the stream, so only
profiles can be submitted. This reasonably also means we can create
"inbox" or "all" streams for foreign profiles as well using the same
stream handler (but of course only for messages we already know about).
To avoid looking up posts for a long time in a large notice database,
the lookback period for the inbox is no longer than the profile creation
date. (this matches the behaviour of Inbox)
Inbox class can probably be removed now.
There was a problem with (specifically at least) PuSHpress for
Wordpress. A previous attempt to perform a DB transaction backfired
because the remote side could connect to the callback before our
commit had gone through.
I take full responsibility for introducing the bug in the first place :)
This will work without much extra effort because there will always be
more notices (higher value) than conversations (so no collisions).
But please run upgrade.php to avoid having an autoincrement id on
conversation table.
Installations using code after 2014-03-01 will have identical
conversation IDs to the initial (conversation root) notice IDs. This
will not affect older installations, which will have very different
values.
require_once lines were required since _plugins_ don't __autoload
Also, Realtime would load the wrong URL for css/js since $this->name()
returns get_class($this) instead of the calling class' __CLASS__.
Many of the microapps are pretty javascript dependant, but at least
we should allow users to get to the new notice field without allowing
javascript to run in the browser. :)
Minutely will NOT necessarily run by the minute, because it depends on
site visitors. Busy sites will be able to do this, but sites where the
visitors (or search engine stuff or api calls) are more than a minute
apart, the interval will be much larger.
Among other things (such as permanent subscriptions), Pubsubhubbub 0.4
removed the "sync" verification method. This means that any incoming
PuSH subscription requests that follow the 0.4 spec won't really
_require_that we handle it as a background process, but if we were to
try direct verification of the subscription - and fail - there's no way
we could pick up the ball again. So _essentially_ we require background
processing with retries.
This means we must implement something like the "poorman cron" or
similar, so background processing can be handled
on-demand/on-site-visit. This is how Friendica, Drupal etc. handles it
and is necessary for environments where we can't run separate queue
daemons.
When the poorman-cron-ish thing is implemented, auto-renewal will work
for all users.

This is more of a proof of concept and will likely not stay in exactly
this form. We should reasonably deliver the entire notice upon webfinger
querying.
