Previously the tracer might receive an 'EXIT' message in the trace
receive loop and treat it as garbage.
Test uses a custom dbg process handler to reliably recreate the
race condition, i.e. the message order {trace, ..}, {'EXIT, ..}.
|
|
Clause matching error for specific test cases was harmless since the
subsequent clause also matched. Errors detected by the server result in
Failed-AVP being sent, which should not lead to a decode error in the
client.
|
|
Outgoing answers missing a Result-Code AVP or setting an E-bit
inappropriately were discarded, but there's no particular reason for
doing so if the answer can be encoded, and the sender has no way of
knowing that their answer has been discarded. It's also inappropriate
that the message be discarded in the relay case. Answers are now sent,
and an error counter incremented.

More than an incoming message can contain ancillary data, which the
gen_sctp and transport suites did not expect. On FreeBSD 10, an
sctp_assoc_change event appears always to contain ancillary data.

Behaviour of character types \d, \w and \s has always been to not match characters

Commit 24993fc2 modified the state even in the case that the new
pool_size option the change was introduced to support was not used.
Doing so made downgrade impossible since old code would not be prepared
for the modified state. Retain a compatible state, so that simple code
replacement is enough.
|
|
On OS X at least. The testcase opens a listening socket, spawns 8
processes that call gen_tcp:accept/1, waits a couple of seconds, and
then spawns 8 processes that call gen_tcp:connect/3. Some of these
occasionally return {error, econnreset}.

Using the fact that transport processes can now be started concurrently.
The suite serialized starts itself when pretending to be diameter
starting a transport process.
|
|
Commit 9a671bf0 removed the need for diameter_sctp to send outgoing
messages through the listening process. That was prior to R5B02, so the
clause isn't need for any upgrade case.
|
|
Stops were aborted at the first failure.
|
|
Which hasn't received any attention for some time. Clean it up, rename
the poorly named peer.erl (it's Diameter *nodes* that are implemented),
and make the it possible to specify arbitrary transport configuration.
|
|
In particular, do away with unnecessary articles in the first sentence
of item lists.
|
|
With testcases that uses restrict_connections and pool_size config to
establish multiple connections between two Diameter nodes, checking for
the expected number of transport processes using
diameter:service_info/2.
|
|
In particular, that starts for the same transport reference can now be
concurrent. Looking up a listener process and starting a new one if not
found did handle this (more than one process could find no listener),
and diameter_sctp assumed there could only be one transport process
waiting for an association.
|
|
Transport processes are started by diameter one at a time. In the
listening case, a transport process accepts a connection, tells the
peer_fsm process, which tells its watchdog process, which tells its
service process, which then starts a new watchdog, which starts a new
peer_fsm, which starts a new transport process, which (finally) goes
about accepting another connection. In other words, not particularly
aggressive in accepting new connections. This behaviour doesn't do
particularly well with a large number of concurrent connections: with
TCP and 250 connecting peers we see connections being refused.
This commit adds the possibilty of configuring a pool of accepting
processes, by way of a new transport option, pool_size. Instead of
diameter:add_transport/2 starting just a single process, it now starts
the configured number, so that instead of a single process waiting for a
connection there's now a pool.
The option is even available for connecting processes, which provides an
alternate to adding multiple transports when multiple connections to the
same peer are required. In practice this also means configuring
{restrict_connections, false}: this is not implicit.
For backwards compatibility, the form of
diameter:service_info(_,transport) differs in the connecting case,
depending on whether or not pool_size is configured.
Note that transport processes for the same transport_ref() can be
started concurrently when pool_size > 1. This places additional
requirements on diameter_{tcp,sctp}, that will be dealt with in a
subsequent commit.

An erroneous lookup option is needed to trigger the bug, and that can only

I was going through application_controller.erl looking for why
something was behaving a certain way, saw a comment about removing
this duplicated code one day, and decided to move that a step forward.

* dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation:
mnesia: Check nodes after protocol negotiation
OTP-12473
|
|
During Mnesia startup, after protocol negotiation, the list of connected
nodes is written to "recover_nodes". This list is later used to merge
the schema.
If Mnesia was stopped on a remote node between the protocol negotiation
and the moment the list is stored in "recover_nodes", the remote node
is still considered running: the value of "recover_nodes" stored during
mnesia_down/1 is overwritten. Therefore, this node may be used to
acquire a write lock on the schema in order to perform the merge. In
this case, the remote node never answers to the lock request and Mnesia
hang forever (application:start(mnesia) never returns).
To fix the problem, we check the list one last time and remove from it
all nodes where Mnesia is stopped. And because there is still a chance
for missing mnesia_down event, handle_cast({mnesia_down, ...}, ...)
writes to recover_nodes again, in addition to mnesia_down/1.
