Custom message format for enif_select
|
|
Make sure to flush all queued emulator logger messages
before starting the test. The trap_exit_badarg could sometimes
leave messages and since the handler and messages now are
handled in different processes this becomes a problem.

Add a simple wrapper script for the socket ttest program(s).
Intended to be used when running a performance test in a
standard shell (bash).

It took "forever" to run the ttest test cases, so the runtime
of these have been adjusted down to 10 seconds (from 60 seconds).

Handle (rcv and snd) buffer set failure.
The number of iterations (message exchanges) that the
traffic ping-cases has been adjusted down (by a factor of 10).
Also, improve skip'ing.

The test case tried to validate the (socket option) protocol,
which is not actually available on OpenBSD. So, add a check
if the option is supported.

The macro (define) IPTOS_MINCOST does not exist
on OpenBSD 6.3.

Added a number of ttest test cases with transport socket.
Server with transport = socket(tcp), active = true and client
using transport = socket(tcp) (and active = false, once and true).

Also fixed a counting error in the server (forgot to include the
header, 16 bytes, in the byte count).

Also a bit of client and server cleanup (remove and cleanup up
some printouts).

Added a number of ttest test cases with transport gen_tcp and socket.

Also a bit of "grouping".

Added a number of ttest test cases with transport gen_tcp.
Server with transport = gen_tcp, active = false and client
using transport = gen_tcp (and active = false, once and true).
Also "fixed" the gen_tcp socket buffer size (default size
was way to small for the "large" messages).

Make length/1 yielding
|
|
The guard BIF `length/1` would calculate the length of the list in one
go without yielding, even if the list was were long. To make it even
worse, the call to `length/1` would only cost a single reduction.
This commit reimplements `length/1` so that it eats a number of
reductions proportional to the length of the list, and yields if the
available reductions run out.

Similar bug as for bxor fixed by abc4fd372d476821448dfb9
Ex:
1> io:format("~.16B\n", [-16#1110000000000000000 band (-1)]).
-1120000000000000000
Wrong result for
(-X bsl WS) band -Y.
where
X is any positive integer
WS is erlang:system_info(wordsize)*8*N where N is 1 or larger
Y is any positive integer smaller than (1 bsl WS)
Fix:
The subtraction of 1 (for 2-complement conversion)
must be carried along all the way to the last words.

This allows bif1/2/3 to share the main part of the code.
The price is that we always need to copy all three temporary registers
when error handling in bodies, but that should be infrequent.
Additionally it makes it a bit harder to read the disasembly since now
the arguments to BIFs are in the reverse order.

Add missing annotations in instrs.tab
|
|
Added a global logger that make it possible to log
from the slave nodes (with "ease").
Also "fixed" the test case that failed on "older"
linux (Ubuntu 14.04). For now we let it skip
instead (we should really check the OS version).
Also corrected a couple of (ping-pong) cases for which
the buffer adjustments did not work.

Assumed the wrong success value ({ok, _} instead of ok) for the
api-to-connect-tcp test case.

Previously the "message interface" between the functions in
socket.erl and the nif-code (socket_nif.c) was "ad hoc".
This has now been changed so that we have a unified message
{'$socket', SockRef | undefined, Tag, Info}
This also has the added advantage of preparing the code for
when we start using the new select-fucntions (with which
its possible to specify your own message). This will be used
in order to get around our eterm "leak" (we will use a simple
counter, maintained in the nif, instead of the [Recv|Send|Acc]Ref
we generate in the erlang code today.
