Add two simple (traffic) counter test cases, to test
counter actions for normal traffic (send and receive
using sendmsg and recvmsg).
One for IPv4 tcp and one for unix-domain-socket stream (tcp).

Corrected both read pkg and byte counter increment for recvfrom
(was actually missing).

When to count read failure and read package count
used number of bytes read instead of just increment (by 1).

We already had the counters. But we did not entirely handle
counter wrap, especially in related to 'iow' (Inform On Wrap).
There was also no way to get to the counter values, so a socket
specific info function was implemented (piggy back on the existing
"global" info function). And since, we have it, we also add
other info in the returned map (number of readers, writers and
acceptors).

Seems the right thing to do as the compiled code is not necessarily
executed by a single CPU thread.
Only warning if old gcc and will work as good/bad as it did before.

Ideally we should ignore all read only filesystems,
but this will have to do for now.
We do this as we don't want disk_sup to report that
a filesystem is almost full if it is read-only.

ETS ordered_set: Improvements to the CA tree implementation
|
|
This commit only affects the implementation of ETS `ordered_set`
tables with the `write_concurrency` option enabled. Such tables are
implemented with a data structure that is called the contention
adapting search tree (CA tree). This commit introduces the following
changes:
* This commit causes a join to be triggered in one randomly selected
base node in about one of 1000 read unlock calls for base node
locks. No such joins happened before this commit. Before this
commit, operations that only acquired looks in read-mode never
triggered any contention adaptation. Therefore, the CA tree could
get stuck in a sub-optimal state in certain scenarios. This could
happen, for example, when a CA tree is first populated with parallel
inserts (which will cause splits of base nodes) and then only
read-only operations are applied to the data structure. Benchmark
results from the
`ets_SUITE:lookup_catree_par_vs_seq_init_benchmark/0` benchmark
function (which is included in this commit) shows that this change
can improve the throughput of the CA tree in the scenario described
above.
* Read-only operations will now also increase values of statistics
counters when they detect that they need to wait for other
operations. Only write operation changed statistics counters before
this commit. This improves the statistics that the adaptation
heuristics is based on.
* Additionally, this commit adds an upper and lower limit to the
contention statistics variables in the base nodes. Such limits did
not exist before this commit. This should, for example, make the CA
tree more responsive to contention after long periods of low
contention.
