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 :)
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.

"[...] posts _local_ users (like you) make won't get data about "repeated by"
from federated users"
This was because the ActivityObject would processShare where the shared object
has a _local_ 'actor' URI. Ostatus_profile would complain this meant that a
"Local user cannot be referenced as remote.".
So we see if the shared activity object's id (URI) is in our Notice table, so
we don't have to processActivity - and can skip ensureActivityObjectProfile.
New plugins:
* LRDD
LRDD implements client-side RFC6415 and RFC7033 resource descriptor
discovery procedures. I.e. LRDD, host-meta and WebFinger stuff.
OStatus and OpenID now depend on the LRDD plugin (XML_XRD).
* WebFinger
This plugin implements the server-side of RFC6415 and RFC7033. Note:
WebFinger technically doesn't handle XRD, but we serve both that and
JRD (JSON Resource Descriptor), depending on Accept header and one
ugly hack to check for old StatusNet installations.
WebFinger depends on LRDD.
We might make this even prettier by using Net_WebFinger, but it is not
currently RFC7033 compliant (no /.well-known/webfinger resource GETs).
Disabling the WebFinger plugin would effectively render your site non-
federated (which might be desired on a private site).
Disabling the LRDD plugin would make your site unable to do modern web
URI lookups (making life just a little bit harder).
In commit e95f77d34c HubSub lost the
'staticGet' function in a consolidation into the Managed_DataObject class.
This was done carelessly by me as HubSub::staticGet was actually taking
two arguments, none of which was a key and merging them in HubSub::hashkey()
(staticGet was renamed getKV 2a4dc77a63).
NOTE: This complements commit 7e4718a4eb which
fixed a similar issue for the Magicsig class.
In commit e95f77d34c Magicsig lost the 'staticGet' function (later renamed to getKV in 2a4dc77a63 ), which was important to properly initialize the Magicsig object (fromString)
I used this hacky sed-command (run it from your GNU Social root, or change the first grep's path to where it actually lies) to do a rough fix on all ::staticGet calls and rename them to ::getKV
sed -i -s -e '/DataObject::staticGet/I!s/::staticGet/::getKV/Ig' $(grep -R ::staticGet `pwd`/* | grep -v -e '^extlib' | grep -v DataObject:: |grep -v "function staticGet"|cut -d: -f1 |sort |uniq)
If you're applying this, remember to change the Managed_DataObject and Memcached_DataObject function definitions of staticGet to getKV!
This might of course take some getting used to, or modification fo StatusNet plugins, but the result is that all the static calls (to staticGet) are now properly made without breaking PHP Strict Standards. Standards are there to be followed (and they caused some very bad confusion when used with get_called_class)
Reasonably any plugin or code that tests for the definition of 'GNUSOCIAL' or similar will take this change into consideration.
In some brief tests, this causes no problems.
In this state however, you would need to modify DB_DataObject to have a static declaration of staticget (and probably pkeyGet). The next commit will change the staticGet overload to a unique function name (like getKV for getKeyValue), which means we can properly call the function by PHP Strict Standards.
The switch to having a function in Managed_DataObject is now being applied
to plugins which can use this as well.
There are some plugins that still use Memcached_DataObject, but these will
be taken care of later.
Output from 0.9.6 PuSH feeds seems to have a rump <author> but no
<activity:actor>. It was overwriting valid and useful data set up at
subscribe time.
This fix tries to avoid overwriting data. However, it may prevent
updates that delete data.
