Up till now all send errors have been translated into a generic
{error, closed}. This patch allows {error, econnreset} to be
returned on send errors when it is detected that the TCP peer
has sent an RST.
|
|
An ECONNRESET is a socket error which tells us that a TCP peer has sent
an RST. The RST indicates that they have aborted the connection and
that the payload we have received should not be considered complete. Up
until now, the implementation of TCP in inet_drv.c has hidden the
receipt of the RST from the user, treating it as though it was just
a FIN terminating the read side of the socket.
There are many cases where user code needs to be able to distinguish
between a socket that was closed normally and one that was aborted.
Setting the option {show_econnreset, true} enables the user to receive
ECONNRESET errors on both active and passive sockets.
A connected socket returned from gen_tcp:accept/1 will inherit the
show_econnreset setting of the listening socket.
By default this option is set to {show_econnreset, false}.
Note that this patch only enables the reporting of ECONNRESET when
the socket is being read from. It does not report ECONNRESET (or
EPIPE) when the user tries to write to a connection when an RST
has already been received. Currently the TCP implementation in
inet_drv.c hides all such send errors from the user in favour
of returning {error, close}. A separate patch will be needed to
enable the reporting of such errors.

A bug in supervisor:get_childspec/2 results in
{error, simple_one_for_one} being returned on every call when the
supervisor strategy is simple_one_for_one.
This commit includes a small refactoring which brings together the
two 'start_child' clauses to make the code easier to follow.

This option has a fun as value. The fun will be called when an
unexpected message arrives. The fun returns either 'skip' or 'report'
to guide the connection_handler what to do.
One usage is to filter out messages that are not wanted in the error
logger as info reports. An example of such a message is the 'etimedout'
tcp error message that will be received if a connection has keep_alive
and the peer is restarted.

This suite tests that upgrade/downgrade works from/to both minor and major versions. It is modelled after the ssl_upgrade_SUITE.
A precondition for success is that the ssh.appup file is correct.

If not unstuck: faulty error messages will appear in error_logger_warn_SUITE.

In the old times there was no binary notation which handled this particulary case, but now we can write big-signed-integer-unit:8 directly in binaries.
The undocumented internal function ssh_bits:erlint/1 is removed.

TLS hash_sign algorithms may have proprietary values see
http://www.iana.org/assignments/tls-parameters/tls-parameters.xhtml
We should add callbacks to let applications handle them.
But for now we do not want to crash if they are present and
let other algorithms be negotiated.

The call_benchmark/1 test case is supposed to return a comment
about the number of RPC calls per second, but the return value
from the function that produces the comment (do_call_benchmark/4)
is ignored. The test case is essentially useless except as a
smoke test.
Simplify the test case and correct the showing of the number of
RPC calls per second, as well as eliminate the use of erlang:now/0.
|
|
|
|
Fix the sorting logic in add_multi_timer() and expand the test case
coverage around this area.
|
|
This is to give a quick end if the test is run a maskin where it can't log in to the OpenSSH server.
