The running time for gen_event_SUITE:hibernate/1 is about 20 seconds
because of 1000 ms sleeps in the test case. Introduce helper
functions to avoid sleeping more than necessary.
While we are it, also remove all ?line macros in the test case.

Refactor the code so that the error test cases for utf16 can
share the code for big and little endian. Do the same for utf32.
The major optimization is the observation that the following code:
byte_size(unicode:characters_to_binary(List, unicode, {utf16,big})
can be replaced with:
2*length(List)
which is much faster. (That optimization is not safe in general,
but for the lists used in the error tests cases, it is.)

unicode_SUITE:binaries_errors/1 is the slowest test case in
unicode_SUITE. Its running time is about 50 seconds on my computer.
Break apart unicode_SUITE:binaries_errors/1 into several test cases
that can run in parallel.
|
|
The compile_pattern/1 function in the binref module is a dummy
function. Therefore, calling binref:match/2 once with the plain
pattern and once with a "pre-compiled" pattern will take twice as
long, but will not help us find more errors.
I shaved off one fourth of the running time for random_ref_comp/1
by eliminating the unnecessary calls to the binref module.
|
|
The most expensive part of random_ref_comp/1 is
do_matches_loop_comp/4. The running time was reduced from roughly
80 seconds to roughly 40 seconds on my computer when I modified
the caller to pre-compile the pattern.
|
|
The time to run io_proto_SUITE:unicode_options_gen/1 on my computer
was about 110 seconds. After modifying the test case so that it
does several file operations in parallel the time was reduced to
about 60 seconds.

* anders/diameter/dpr/OTP-12609:
Discard incoming/outgoing requests after incoming DPR
Add transport_opt() dpr_timeout
Be lenient with errors in incoming DPR
|
|
Despite claims of full backwards compatibility, the text of RFC 6733
changes the interpretation of unspecified values in a DiameterURI. In
particular, 3588 says that the default port and transport are 3868 and
sctp respectively, while 6733 says it's either 3868/tcp (aaa) or
5658/tcp (aaas). The 3588 defaults were used regardless, but now use
them only if the common dictionary is diameter_gen_base_rfc3588. The
6733 defaults are used otherwise.
This kind of change in the standard can lead to interop problems, since
a node has to know which RFC its peer is following to know that it will
properly interpret missing URI components. Encode of a URI includes all
components to avoid such confusion.
That said, note that the defaults in the diameter_uri record have *not*
been changed. This avoids breaking code that depends on them, but the
risk is that such code sends inappropriate values. The record defaults
may be changed in a future release, to force values to be explicitly
specified.
|
|
Both RFC 3588 and 6733 disallow the combination. Make its encode fail.

To make them a bit more flexible. Can now do things like this:
server:start([{'Product-Name', "Bob"}]),
server:listen({tcp, [{capx_timeout, 2000}]})
Beware that the latter is completely different from this:
server:listen(tcp, [{capx_timeout, 2000}])
|
|
Since there's no reason to reject a client that wants to establish
multiple connections, given that diameter can handle it.
|
|
So as to do what's now recommended in diameter(1), in the grandparent
commit.
|
|
By adding string decode or not in the server or client as another
combination. Run all traffic cases in parallel: remove the sequential
tests. Common test seems unable to deal with {group, X, [parallel]}
within a group.

To control whether stringish Diameter types are decoded to string or
left as binary. The motivation is the same as in the parent commit: to
avoid large strings being copied when incoming Diameter messages are
passed between processes; or *if* in the case of messages destined for
handle_request and handle_answer callbacks, since these are decoded in
the dedicated processes that the callbacks take place in. It would be
possible to do something about other messages without requiring an
option, but disabling the decode is the most effective.
The value is a boolean(), true being the default for backwards
compatibility. Setting false causes both diameter_caps records and
decoded messages to contain binary() in relevant places that previously
had string(): diameter_app(3) callbacks need to be prepared for the
change.
The Diameter types affected are OctetString and the derived types that
can contain arbitrarily large values: OctetString, UTF8String,
DiameterIdentity, DiameterURI, IPFilterRule, and QoSFilterRule. Time and
Address are unaffected.
The DiameterURI decode has been redone using re(3), which both
simplifies and does away with a vulnerability resulting from the
conversion of arbitrary strings to atom.
The solution continues the use and abuse of the process dictionary for
encode/decode purposes, last seen in commit 0f9cdba.

Both incoming and outgoing Diameter messages pass through two or three
processes, depending on whether they're incoming or outgoing: the
transport process and corresponding peer_fsm process and (for incoming)
watchdog processes. Since terms other than binary are copied when
passing process boundaries, large terms lead to copying that can be
problematic, if frequent enough. Since only the bin and transport_data
fields of a diameter_packet record are needed by the transport process,
discard others when sending outgoing messages.
Strictly speaking, the statement that only the aforementioned fields are
needed by the transport process depends on the transport process. It's
true of those implemented by diameter (in diameter_tcp and
diameter_sctp), but an implementation that makes use of other fields is
assuming more than the documentation in diameter_transport(3) promises.

With the same motivation as in commits 5bd2d72 and b1fd629.
As in the latter, incoming DPR is the only exception.
|
|
To cause a peer connection to be closed following an outgoing DPA, in
case the peer fails to do so. It is the recipient of DPA that should
close the connection according to RFC 6733.
|
|
To avoid having the peer interpret the error as meaning the connection
shouldn't be closed, which probably does more harm than ignoring
syntactic errors in the DPR.
Note that RFC 6733 says this about incoming DPR, in 5.4 Disconnecting
Peer Connections:
Upon receipt of the message, the Disconnect-Peer-Answer message is
returned, which SHOULD contain an error if messages have recently been
forwarded, and are likely in flight, which would otherwise cause a race
condition.
The race here is presumably between answers to forwarded requests and
the outgoing DPA, but we have no handling for this: whether or not there
are pending answers is irrelevant to how DPR is answered. It's
questionable that a peer should be able to prevent disconnection in any
case: it has to be the node sending DPR that decides if it's approriate,
and the peer should take it as an indication of what's coming.
Incoming DPA is already treated leniently: the only error that's not
ignored is mismatching End-to-End and Hop-by-Hop Identifiers, since
there's no distinguishing an erroneous value from an unsolicited DPA.
This mismatch could also be ignored, which is the case for DWA for
example, but this problem is already dealt with by dpa_timeout, which
causes a connection to be closed even when the expected DPA isn't
received.

6.1.9 of RFC 6733 states this:
A relay or proxy agent MUST append a Route-Record AVP to all requests
forwarded.
The AVP was inserted as the head of the AVP list, not appended, since
the entire AVP list was reversed relative to the received order.
Thanks to Andrzej Trawiński.

These are requests that diameter itself sends. It's previously been
possible to send them, but answers timed out at the caller since they
were discarded in diameter_watchdog. Answers will still timeout, but now
the requests are discarded before being sent.
|
|
DPR is sent by diameter at application shutdown, service stop, or
transport removal. It has been possible to send the request with
diameter:call/4, but the answer was discarded, instead of the transport
process being terminated. This commit causes DPR to be handled in the
same way regardless of whether it's sent by diameter or by
diameter:call/4.
Note that the behaviour subsequent to DPA is unchanged. In particular,
in the connecting case, the closed connection will be reestablished
after a connect_timer expiry unless the transport is removed. The more
probable use case is the listening case, to disconnect a single peer
associated with a listening transport.
|
|
To make the default DPA timeout configurable. The timeout say how many
milliseconds to wait for DPA in response to an outgoing DPR before
terminating the transport process regardless.
|
|
That currently fails when the resulting DPA is regarded as unsolicited
in diameter_peer_fsm, causing the request to timeout at the caller.
|
|
Since there's a race between an answer being sent and the connection
being closed upon the reception of DPA that's likely to be lost, and
because of the questionability of sending messages after DPR, as
discussed in the parent commit. An exception is made for DPR so that
simultaneous DPR in both directions doesn't result in it being discarded
on both ends.
|
|
RFC 6733 isn't terribly clear about what should happen to incoming or
outgoing messages once DPR is sent and the Peer State Machine
transitions into state Closing. There's no event for this in section
5.6, Peer State Machine, and no clarification in section 5.4,
Disconnecting Peer Connections. There is a little bit of discussion in
2.1.1, SCTP Guidelines, in relation to unordered message delivery, but
the tone there is that messages might be received after DPR because of
unordered delivery, not because they were actually sent after DPR.
Discarding outgoing answers may do more harm than good, but requests are
more likely to be unexpected, as has been seen to be the case with DWR
following DPR. DPR indicates a desire to close the connection: discard
any subsequent outgoing requests.
