The call to the megaco_filter/1 function is broken. It will cause
a badmatch if the megaco_filter/1 would return a different list than
its argument. Since the test case has not failed, megaco_filter/1
has no effect and can be removed.

If there is no crypto there will be no ssh and thus
alot of undefined functions will appear in common_test.

Set absolute limit on number of threads in ethread_SUITE
OTP-9130

Win64 has no limit on number of threads, at least not one you will reach
before the memory gets exhausted on a mainstream machine. Therefore
the testcase max_threads has to stop at some point before we consume
all virtual memory in the machine. An arbitrary limit of 80000 threads
was added.

Write some extra log files for easy access by other tools.

On my Mac, the highest successful value was 7673. The new value
provides some safety margin.

The MIB compiler has changed how it reports syntax errors.

* dev:
erts: Add a sanity check to autoimport_SUITE
erts: Fix failing autoimport test case
|
|
|
|
If we fail to parse out any functions from erlang.xml, make sure
that we fail.
|
|
The autoimport_SUITE:autoimport/1 test case would interpret
data type definitions as function calls. Fix this by skipping
to the <funcs> tag before starting to collect function names.

* dev:
erlc_SUITE: Fix arg_overflow/1 test case
|
|
In commit be8759e68b337524c056b8bb757ea68c9996d863, a buffer overflow
was fixed in erlc and the erlc_SUITE:arg_overflow/1 test case was
added. That test cases invokes erlc with 10000 -D options, which will
result in 'erl' being invoked with more than 30000 arguments.
On some platforms, the test case will fail for the wrong reason:
* 64-bit Linux kernels before 2.6.23 limit the number of arguments in
an excvp() call to 16383. (See "Number of arguments and maximum length
of one argument" in http://www.in-ulm.de/~mascheck/various/argmax/.)
* The command shell in Windows limits the size of the command line to
8191 characters.
Depending on the platform, pass a different number of -D options
to erlc. Since the size of the options does not matter for this
test case, make the options as short as possible by generating
numbers in base 36.

The ethread atomics API now also provide double word size atomics.
Double word size atomics are implemented using native atomic
instructions on x86 (when the cmpxchg8b instruction is available)
and on x86_64 (when the cmpxchg16b instruction is available). On
other hardware where 32-bit atomics or word size atomics are
available, an optimized fallback is used; otherwise, a spinlock,
or a mutex based fallback is used.
The ethread library now performs runtime tests for presence of
hardware features, such as for example SSE2 instructions, instead
of requiring this to be determined at compile time.
There are now functions implementing each atomic operation with the
following implied memory barrier semantics: none, read, write,
acquire, release, and full. Some of the operation-barrier
combinations aren't especially useful. But instead of filtering
useful ones out, and potentially miss a useful one, we implement
them all.
A much smaller set of functionality for native atomics are required
to be implemented than before. More or less only cmpxchg and a
membar macro are required to be implemented for each atomic size.
Other functions will automatically be constructed from these. It is,
of course, often wise to implement more that this if possible from a
performance perspective.

For some reason pthread_create() crashes when more
threads cannot be created, instead of returning an
error code on our MacOS X Leopard machine...

"-f" is a non-standard chmod option which at least SGI IRIX and HP UX do
not support. As the only effect of the "-f" flag is to suppress warning
messages, it can be safely omitted.

* sf/erts_de_busy_limit:
Add flag-based setting for the distribution buffer busy limit
|
|
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.

Check buffer operations and increase the size of the buffer used for
holding command line arguments, since the "-D" switch will be expanded
into 3 arguments when passed to erl.
