1652122: fix infinite recursion in opensrf.system.method.all
Under certain circumstances, calling opensrf.system.method.all on a
Perl service can result in an infinite recursion when attempting to
serialize an OpenSRF::Application object to JSON. In particular,
this was observed to happen when doing an introspection of
the opensrf.settings service.
This patch avoids the infinite recursion (and consequent memory
leak) by ensuring that the 'session' key is slated for exclusion
from serialization from OpenSRF::Application objects during
bootstrapping.
Note that the problem does not affect all Perl services; if a
Perl service declares at least one streaming method, the auto-registration
of the .atomic method will result in 'session'-stripping.
This patch fixes a regression introduced in bug
1350457.
To test
-------
[1] Run 'introspect opensrf.settings' via srfsh; observe
that it never returns and that the opensrf.settings drone
will grow in memory sized until killed.
[2] Apply the patch, then repeat step 1. This time, the
request should succeed.

There is a pattern in the wild of using OpenSRF's method_lookup() facility
to decide between one of several local methods when delegating to pre-existing
logic. Often times, we want to simply hand control over to another method,
but the output of a subrequest's run() is an array of results. The caller has
to know if, and how, to restructure the result for the client.
Instead, we can now call dispatch() instead of run() and have OpenSRF session
control completely passed to the delegate code. This way, the delegate code
need not know anything about its caller, and vice versa.

sent in the future and we are below some threshold of combined message size.
The default for that threshold is 25Kb.
* OpenSRF message chunking -- Break up large OpenSRF messages across
multiple XMPP envelopes. This is implemented with a new OpenSRF message type.
C, Perl, and Javascript libraries are taught how to reconstruct chunked
messages. The default chunking threshold is 50Kb, just a bit below the default
ejabberd max stanza size of 64Kb.
This patch in particular renames "chunking" to "bundling", then

1494486: Limit damage caused by dropped drone XMPP sockets
It is apparently possible for drones to get into a state where their XMPP
socket is closed but they don't notice. This is bad because the drone can
continue to receive requests from its listener but can no longer respond
to them. To limit the pain this can cause, we should kill the drone as soon
as we notice this condition.
To avoid overhead, this commit notices when the socket returns an error (or
raises a signal, in Perl) upon write, and exits immediately. One message
will be lost, but the drone will no longer be a black hole that does nothing
but absorb requests it can never fill.
To test
-------
[1] Start an OpenSRF stack and look for a drone process.
[2] Use lsof to identify which socket that drone is using
to talk to XMPP.
[3] Use gdb to attach to the process and close the socket, e.g.,
$ gdb -p $PID
(gdb) p close(11) # or whatever the socket number was
(gdb) c
[4] Use srfsh to make requests of that service. Eventually, one
of them will hit the drone.
[5] Sans patch, the request will get handled by the drone, but
the results will never get sent, and the drone will remain
available to handle other requests.
[6] With the patch, the drone will exit when it discovers that it
can no longer write to the XMPP socket.

1002028: Cross Origin Resource Sharing for OpenSRF
Background
----------
Browsers' same-origin policy currently restricts requests to the current
website's domain to prevent various nefarious scenarios. However,
because APIs and other web resources need to remain open to cross-site
use Cross Origin Resource Sharing (CORS) was created to allow services
to formally authorize cross-origin requests. CORS makes it simple to use
OpenSRF's HTTP translator and gateway APIs on websites using separate
domains.
Example Scenarios
-----------------
1) A library would like an AJAX-driven "quicksearch" box on their main
site, which is hosted on a different domain than their catalog.
2) A developer wants to create new web applications and services that
tie into Evergreen, but does not wish to install EG locally or
configure a proxy.
Implementation
--------------
The function crossOriginHeaders() has been added to apachetools.c.
Incoming requests are checked to see if they have an Origin header. The
value of the Origin header is checked against a whitelist defined in
opensrf_core.xml config (XPath: /config/gateway/cross_origin/origin).
The function returns 1 if CORS headers have been added to the response.
Notes
-----
* The OpenSRF Javascript client library (opensrf.js) defaults to the root
of the current web host "/osrf-http-translator." In addition, synchronous
requests are presumed in some situations: resulting in the oncomplete
method never returning (Blocking requests are not possible with cross-
domain XHR.)
* It is also possible to enable CORS with the Apache "set header"
configuration directive. However, this means that the necessary headers
would be appended to every response.
