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.

Comparison of exact terms could cause faulty term tests.
This was caused by a faulty (too small) internal type.
Symptom:
-1 = erts_internal:cmp_term(2147483648,0). %% wrong
Correct:
1 = erts_internal:cmp_term(2147483648,0).

* anders/diameter/DiameterURI/OTP-12589:
Adapt to changed DiameterURI defaults in RFC 6733
Reject transport=udp;protocol=diameter at DiameterURI encode
|
|
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.

from map_to_validated_list

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.
