In a federated system, "@nickname" is insufficient to uniquely
identify a user. However, it's a very convenient idiom. We need to
guess from context who 'nickname' refers to.
Previously, we were using the sender's profile (or what we knew about
them) as the only context. So, we assumed that they'd be mentioning to
someone they followed, or someone who followed them, or someone on
their own server.
Now, we include the notice information for context. We check to see if
the notice is a reply to another notice, and if the author of the
original notice has the nickname 'nickname', then the mention is
probably for them. Alternately, if the original notice mentions someone
with nickname 'nickname', then this notice is probably referring to
_them_.
Doing this kind of context sleuthing means we have to render the
content very late in the notice-saving process.
* 'testing' of gitorious.org:statusnet/mainline:
init_conversation.php script to copy old notice conversations into the conversation table
cache results of webfinger lookups
Parse an hcard for hints, if available
use new hcard method for webfinger
add hkit for hCard parsing
use new dedicated hcard method for Webfinger profile
Add an hcard action
* 'testing' of gitorious.org:statusnet/mainline:
OStatus: if no <link> available and no profileurl hint passed in, use object id if it's an HTTP(S) URL. Fixes profile link for Google accounts.
Tweak common_url_to_nickname to take the last path component; fixes pulling nicks from Google profile pages (path is "/profile/<nickname>")
Fix bug on subscribe/unsubscribe in profile lists. Bogus call to nonexisting profile->getProfile() was masked by DB_DataObject
A dedicated hcard action for users. Our profile page includes
an hcard, but it's so full of other hcards that it's ambiguous which
one is the "real" one. So, this one make sense for meaning, "This is
my hcard."
* 'testing' of gitorious.org:statusnet/mainline:
Not sure how this ended up in wrong-cased dir...
OStatus: fix remote groups to work with new user_groups/local_groups split.
Conflicts:
classes/User_group.php
- fix <activity:subject> generation so we get the profile info (what's available so far)
- use id instead of nickname for group join/leave forms so we can join/leave remote groups
while the rest of the groups UI remains limited to local groups
(plugins are responsible for making sure remote notifications and permission checks are done)
- fix remote notification when joining group through OStatus's remote subscribe form
* 'testing' of gitorious.org:statusnet/mainline:
Merge StatusNet core localization updates from 0.9.x branch
Fix update_po_templates.php to support the plural and context variants of _m() in plugins
Drop HTMLPurifier; we don't need its extra capabilities and we're already using htmLawed which is lighter-weight.
OStatus: handle update-profile Salmon pings
Revert "Updated jQuery Form Plugin from v2.17 to v2.36"
OStatus: disable HTMLPurify cache unless we've configured a writable path for it.
- add event hooks to profile update pings
- send Salmon pings with custom update-profile event to OStatus subscribees and groups (subscribers will see it on your next post)
- fix OStatus queues with overlong transport names, should work on DB queues now
- Ostatus_profile::notifyActivity() and ::notifyDeferred() now can take XML, Notice, or Activity for convenience
the shorthand that I've proposed at
http://microformats.org/wiki/geo-brainstorming#latitude_longitude_shorthand_and_geo_link
If anyone wants to pick up on where the discussion was left off or
get more implementation support by other sites and software, and be
recognized by parsers, I'd be happy to go back to the shorthand.
Because you know, it actually makes a lot of sense.
- added rel="ostatus:attention" links for group delivery
- added events for plugins to override group profile/permalink pages
- pulled Notice::saveGroups up to save-time so we can override;
it's relatively cheap and gives us a clean list of target
groups for distrib time even with customized delivery.
- fixed notice::getGroups to return group objects as expected
- added some doc on new parameters to Notice::saveNew
- 'groups' list of group IDs to push to in place of parsing
- messages that come in via PuSH and contain local group targets
are delivered to local group members
- messages that come in via PuSH and contain remote group targets
are delivered to local members of the remote group
Todo:
- handle group posts that only come through Salmon
- handle conflicts in case something comes in both through Salmon and PuSH
- better source verification
- need a cleaner interface to look up groups by URI
- need a way to handle remote groups with conflicting names
Combined the code that finds mentions of other profiles into one place.
common_find_mentions() finds mentions and calls hooks to allow
supplemental syntax for mentions (like OStatus).
common_linkify_mentions() links mentions.
common_linkify_mention() links a mention.
Notice::saveReplies() now uses common_find_mentions() instead of
trying to parse everything again.
I changed the way that tag: URIs are minted, so we now use the right
base. Ideally most of these would use HTTP URIs instead, but for
now at least they use the right base.
We've been making pretty crummy tag: URIs for a while. We should
continue to favor HTTP URIs, since it's nice to be able to discover
things about an object you've shared the ID of. Where that's not
possible, this makes nicer tag URIs.
The subs_* functions in subs.php have made a lot of assumptions
about users versus profiles. I've refactored the functions to
be methods of the Subscription class instead, and to use Profile
objects throughout.
Some of the checks for blocks or existing subscriptions depended
on users or profiles, so I've moved those methods around a bit.
I've left stubs for the subs_* functions until we get time to replace
them.
All breakout queues that we're going to need to listen to now need to be explicitly listed in $config['queue']['breakout'].
Until XMPP is moved to component model, this setting will let the individual processes work with their own queues:
$config['queue']['breakout'][] = 'xmpp/xmppout/' . $config['site']['nickname'];
- Multiplexing queues into groups and for multiple sites.
- Sharing vs breakout configurable per site and per queue via $config['queue']['breakout']
- Detect how many times a message is redelivered, discard if it's killed too many daemons
- count configurable with $config['queue']['max_retries']
- can dump the items to files in $config['queue']['dead_letter_dir']
Queue daemon memory & resource leak fixes:
- avoid unnecessary reconnections to memcached server (switch persistent connections back in on second initialization, assuming it's child process)
- monkey-patch for leaky .ini loads in DB_DataObject::databaseStructure() - was leaking 200k per active switch
- applied leak fixes to Status_network as well, using intermediate base Safe_DataObject for both it and Memcache_DataObject
Misc queue fixes:
- correct handling of child processes exiting due to signal termination instead of regular exit
- shutdown instead of infinite respawn loop if we're already past the soft memory limit at startup
- Added --all option for xmppdaemon... still opens one xmpp connection per site that has xmpp active
Cache updates:
- add Cache::increment() method with native support for memcached atomic increment
* skip unnecessary unsubscribes on graceful shutdown -- takes a long time for many queues, slows down our restarts when hitting graceful mem limit
* fix control channel (was broken when we switched to support multiple queue servers)
* detection of group feeds is currently a nasty hack based on presence of '/groups/' in URL -- should use some property on the feed?
* listing for the remote group is kinda cruddy; needs to be named more cleanly
* still need to establish per-author profiles (easier once we have the updated Atom code in)
* group delivery probably not right yet
* saving of group messages still triggering some weird behavior
Added support for since_id and max_id on group timeline feeds as a free extra. Enjoy!
* Treat linkless feed posts as status updates; drop the "New post:" prefix and quotes on them.
* Use stable user IDs for atom/rss2 feed links instead of unstable nicknames
* Pull Atom feed preferentially when subscribing -- can now put the remote user's profile page straight into the feed subscription form and get to the right place.
* Clean up naming for push endpoints
* renamed FeedSub plugin to OStatus
* now setting avatar on subscriptions
* general fixes for subscription
* integrated PuSH hub to handle only user timelines on canonical ID url; sends updates directly
* set $config['feedsub']['nohub'] = true to test w/ foreign feeds that don't have hubs (won't actually receive updates though)
* a few bits of code documentation
* HMAC support for verified distributions (safest if sub setup is on HTTPS)
And a couple core changes:
* minimizing HTML output for exceptions in API requests to aid in debugging
* fix for rel=self link in apitimelineuser when id given
This does not not yet include any of the individual subscription management (Salmon notifications for sub/unsub, etc) nor a nice UI for user subscriptions.
Needs some further cleanup to treat posts as status updates instead of link references.
