* lukas/erts/testfixes-19:
erts: Increase bif and nif call_time trace test
erts: Fix distribution_SUITE:bulk_send_bigbig on windows
erts: Ensure bs_add_overflow test has enough memory
kernel: Better explain controlling_process' tcp behaviour
kernel: Fix t_recv_delim on bsd
os_mon: Make sure to start/stop os_mon in tests correctly
ssl: Fix use_interface dist_SSL test
erl_interface: Fix signed int overflow tc bug
erts: fix atom_roundtrip_r15b tc
erts: Require more memory for debug tests
|
|
The granualarity of the windows time sometimes makes timer:tc
return 0 as the time taken for the test. Change this to use
the most common time instead.
|
|
if node fails to start, just skip testcase
|
|
For -start_epmd, check that the node starts properly and that we can
ping it.
For -epmd_module, start two nodes that can communicate only because we
supply the correct port number through a command line argument.

* henrik/update-copyrightyear:

Those clause are obsolete and never used by common_test.
|
|
The macro ?t is deprecated. Replace its use with 'test_server'.

|
As a first step to removing the test_server application as
as its own separate application, change the inclusion of
test_server.hrl to an inclusion of ct.hrl and remove the
inclusion of test_server_line.hrl.

* lukas/fix_erts_testcases/OTP-9596:
Skip create_big_boot on platforms without crypto
Remove test_server path instead of cwd for clash test
Skip getaddr_v6 test if on the ipv4_only host
Use static port for old solaris versions
Extend time to wait for zone files to be loaded
Allow out of memory exception for max_port checks
Extend slave start timeout for windows tests
Double timeout to make sure debug builds pass
Use now instead of os:timestamp
Increase timeout in scheduler_suspend for slow platforms
Skip update_cpu_info if 'taskset' cannot be found

bad_dist_ext_connection_id/1 used the same names for the slave
nodes as bad_dist_ext_receive/1, which would cause it to fail if
bad_dist_ext_receive/1 failed.

Id: OTP-8912
This patch creates a new family of flags with the "+z" prefix. It
further creates a new configuration option called "dbbl" (which is the
first letter of the name dist_buf_busy_limit). Example usage of this
flag would be "+zdbbl 1048576".
This patch creates an adjustable buffer limit for the amount of data
that may be buffered by the erlang distribution code (in dist.c
specifically). Before this patch, this hard-coded constant was used:
#define ERTS_DE_BUSY_LIMIT (128*1024)
When large binaries are transmitted between nodes (or simply a lot of
medium-sized binaries), it is very easy to hit the old 128KB limit.
Processes that use the erlang:system_monitor() BIF to monitor system
events can be spammed by {monitor, busy_dist_port, ...} message tuples
at rates of tens to even hundreds of messages/second.
A larger buffer limit will allow processes to buffer more outgoing
messages over the distribution. When the buffer limit has been
reached, sending processes will be suspended until the buffer size has
shrunk. The buffer limit is per distribution channel. A higher limit
will give lower latency and higher throughput at the expense of
higher memory usage.
A variation of this patch has been in commercial production use in at
least two companies that the author is aware of. Larger buffer values
can reduce the number of {monitor, busy_dist_port, ...} system
messages drastically, lower overall messaging latencies, and prevent
false timeouts and 'nodedown' messages in extremely busy Mnesia systems.
Test suite: there are two tests:
a. In erlexec_SUITE.erl to test basic set & get of the value
b. In distribution_SUITE.erl, to verify that setting +zdbbl very
low will actually change behavior.

* bg/opt-receive:
Test that gen_server:call/2,3 are fast even with a huge message queue
erts: Add tests for the receive optimization
Update primary bootstrap
erts: Implement recv_mark/1 and recv_set/1 for real
compiler tests: Cover the error handling code in beam_receive
compiler test: Test optimization of receive statements
Optimize selective receives in the presence of a large message queue
Introduce the new recv_mark/1 and recv_mark/1 instructions
Compile tests that communicate with R12 nodes with the r12 option
Move p_run/2 to test_lib
gen: Inline wait_resp_mon/2 to help the compiler optimize
OTP-8623 bg/opt-receive
reveive statements that can only read out a newly created reference are now
specially optimized so that it will execute in constant time regardless of
the number of messages in the receive queue for the process. That
optimization will benefit calls to gen_server:call(). (See gen:do_call/4
for an example of a receive statement that will be optimized.)
|
|
R12 nodes cannot load code that use the optimized receive that
we are about to implement.
