* anders/diameter/watchdog_leak/OTP-11019:
Minor doc fix
Add testcase to exercise reconnect behaviour
Fix watchdog table leak
|
|
|
|
|
|
|
|
In particular, remove timing dependence by using diameter_reg:wait/1 to
wait on the term registered by diameter_{tcp,sctp} when opening a
listening socket.
|
|
Note that the semantics of client:connect/1 have changed slightly: the
second element in an argument 3-tuple is a remote address, the local
address being the transport module's default. Previously it was
interpreted as a common local/remote address.
|
|
Use the default address address (as selected by gen_tcp) if none is
configured, passing it in the new 'connected' message introduced by the
previous commit.
The corresponding update to diameter_sctp has to wait until problems
with inet:sockname/1 are resolved: the function currently only returns
one address, and sometimes {0,0,0,0}. See OTP-11018.
|
|
A transport module can return a local address list from its start/3
function in order to specify addresses to be used as Host-IP-Address
during capabilities exchange. Now allow addresses to be communicated in
a 'connected' message in the case of a connecting transport, so that
diameter_tcp (in particular) can make local address configuration
optional, communicating the gen_tcp default after connection
establishment instead.
|
|
A service process maintains a table keyed on watchdog process pids. When
a watchdog process dies the corresponding entry should be removed but
this was broken in commit f115a9f7, causing entries with watchdog state
DOWN to accumulate.
Watchdog processes die as a result of diameter:remove_transport/2, or
when a peer reestablishes a connection in the listening case. Neither is
typically a frequent occurrence.
The fault manifests itself in the return value of
diameter:service_info(SvcName, transport), which displays entries for
watchdog processes that are no longer alive.

* anders/diameter/service_config/OTP-11017:
Fix handling of unknown options to diameter:start_service/2
|
|
Diameter = the protocol
diameter = the Erlang application
|
|
{error, Reason} is now returned, instead of the options being ignored.
Note that diameter:add_transport/2 purposely ignores unknown options and
that the behaviour is documented. This is historic: some users depend on
it in order to store their own options for identifying transport config,
instead of using the reference returned by add_transport.
|
|
* anders/diameter/app_not_configured/OTP-10972:
Fix faulty sequence validation
Add config suite
Deal with config errors detected at transport start less brutally
Move most transport_opt() validation into diameter_config
Minor doc/spec fix
Minor diameter_lib cleanup
|
|
The validation of {sequence, {H,N}} incorrectly checked that H was an
N-bit integer, instead of the intended 32-N.
|
|
To verify return values from diameter:start_service/2 and
diameter:add_transport/2 when passing various config.
|
|
Crashing watchdog and peer_fsm processes was somewhat unseemly. Emit an
error report and die silently instead.
|
|
Faulty configuration was previously passed directly on to watchdog and
peer_fsm processes, diameter:add_transport/2 happily returning ok and
the error resulting on failure of watchdog and/or peer_fsm processes.
Now check for errors before getting this far, returning {error, Reason}
from diameter:add_transport/2 when one is detected. There are still
some errors that can only be detected after transport start (eg. a
misbehaving callback) but most will be caught early.
|
|
'infinity' is a valid transport_config timeout.
|
|
Remove unused functions, add dialyzer specs, make wait/1 less fallible.
|
|
|
|
Instead of from the installation.
|
|
Fix errors and omissions related to dictionary compilation.
|
|
From compiler suite.
|
|
That is, code installed under examples/code in an installation.
|
|
Fix a broken include in example code, remove an inappropriate ct:pal/2
outside of a testcase, echo more info from test/Makefile.

RFC 6733 has changed the arity of Vendor-Id in this Grouped AVP, from 1*
in RFC 3588 to 1 in RFC 6773. This impacts the generated dictionary
modules: Vendor-Id is expected to be list-valued in the 3588 dictionary,
integer-valued in the 6733 dictionary. This, in turn, breaks the
independence of capabilities configuration on a service or transport
from the dictionary that will be used to encode an outgoing CER or CEA.
This commit fixes this by massaging any Vendor-Specific-Application-Id
config as appropriate when constructing CER or CEA for a given
dictionary.

|
Allow both share_peers and use_shared_peers to be a list of nodes, or a
function that returns a list of nodes.
|
|
|
|
|
|
This is the functionality that allows transports to be shared between
identically-named services on different nodes, which has been neither
documented nor tested (until now).
|
|
Make it just a number of timeouts, without a new DWR being sent.
|
|
|
|
Count watchdog messages instead when this is an alternative.
|
|
Counters read by diameter:service_info(SvcName, transport) can be
selected at the same time as the diameter_stats server is folding them
into another key, possibly resulting in inaccurate values. Have
diameter_stats select from the server process to avoid this and add
diameter_stats:sum/1 to sum values from all contributors on a given
term.
|
|
|
|
To make the number of watchdogs sent before the transitions REOPEN ->
OKAY and OKAY -> SUSPECT configurable. Using anything other then the
default config is non-standard and should only be used for test.

* anders/diameter/SoC/OTP-10688:
Add RFC 6733 commentary to SoC chapter
Add RFC 6737 Capabilities Update dictionary
Remove cruft from doc Makefile
|
|
The commentary is not yet complete. It currently stops at chapter 4 of
the RFC.
|
|
|
|
Although it's neither built nor supported in code yet.
