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.

The following sequence would be wrongly optimized into a
i_get_tuple_element2 instruction, reading an element from the
wrong tuple:
{get_tuple_element,{x,0},1,{x,0}}.
{get_tuple_element,{x,0},2,{x,1}}.

This reverts commit 70dbf671a8196110d2aee2e7507afc2c2c75183f.
As the comment of 70dbf671a8 itself indicates, that "fix" is not really
necessary. It has, however, the bad effect of always consuming reductions of the
process you want to know reduction from, that is you can't meassure reduction
count without affecting it.

Add a pattern field to the (beginning of the) socket descriptor.
To make it more easy to spot memory over-writes. One pattern
for create and one for dtor. Also reset various fields of the
descriptor at dtor.

Rebase (on maint as of 20190529) resulted in a number of
issues. Mostly in the (esock) test suite.

The script used the wrong variable for active (async).
|
|
Tests on Darwin Kernel Version 18.2.0 reveled some
problems handling connect (on that platform).
It seems that calling connect the second time is not needed
(it results in eisconn), so we needed to handle that case,
which we now do.
|
|
Changed tag type tpo opaque. Also added connect (monitor and
process) cleanup.
OTP-15731
|
|
Had forgot about the connect function. But it can now also
handle the Timeout = nowait, maybe resulting in a select.
Required some nif work also...

OTP-15731
|
|
Attempted to implement a common report function for
the time test (ttest). Not complete.
|
|
Updated the ttest test(s) to handle async properly.
OTP-15731
|
|
|
|
The return value for an async call (Timeout = nowait) will now
(normally) result in a {select, SelectInfo} instead (if a select
was performed).
OTP-15731
|
|
If another process closes the socket, the caller will
receive an abort message instead (of the select message).
OTP-15731
|
|
Add recv and recvmsg test case testing the abort message
received when "another" process closes a socket. Multiple
readers for good measure.
|
|
Add accept test case testing the abort message received
when "another" process closes a socket. Multiple accept(ors)
for good measure.
|
|
Add recvmsg test case testing the abort message received
when "another" process closes a socket. Multiple readers
for good measure.
