Add test cases for tcp local socket close for the accept function.
OTP-14831
|
|
Add test cases for udp local socket close for UDP recvfrom and
recvmsg.
OTP-14831
|
|
The receive response local close tcp cases was extended
wityh two more handler (readers).

Add name to evaluator printouts. Also added timetraps to all test-
cases to shorten the time to wait in case a test case fails.

When a module has been purged from memory, any literals belonging
to that module will be copied to all processes that hold references
to them.
The max heap size limit would be ignored in the garbage collection
initiated when copying literals to a process. If the max heap size
was exceeded, the process would typically be terminated in the
following garbage collection.
Since the process would be killed anyway later, kill the process
before copying a literal that would make it exceed its max heap
size.
While at it, also fix a potential bug in `erlang:garbage_collect/0`.
If it was found that the max heap sized had been exceeded while
executing `erlang:garbage_collect/0`, the process would enter a
kind of zombie state instead of being properly terminated.

If the process had more free space than reductions it could run a
lot longer than it was supposed to. It didn't honor the number of
reductions going in either, nor did it bump reductions when
returning its result or erroring out.
This commit also removes this function from a work function in
scheduler_SUITE as it's extremely sensitive to the number of
reductions spent in the test, causing
equal_and_high_with_part_time_max to fail on some machines.

Fix an endless rescheduling loop when a process is executing process_info(self(), ...)

If net_kernel "forgets" to abort a connection (as it currently might),
the garbage collection of a distribution entry could cause node lists
to enter an inconsistent state.

A lot of erts internal messages used behind APIs to create
non-blocking calls, e.g. port_command, would cause the seq_trace
token to be cleared from the caller when it should not.
This commit fixes that and adds asserts that makes sure
that all messages sent have to correct token set.
Fixes: ERL-602

Optimise creation of anonymous functions
|
|
This introduces a similar optimisation for normal funs
to what was introduced for external funs in #1725.
It is possible to allocate the fun as a literal, if it does not capture
the environment (i.e. it does not close over any variables).
Unfortunately it's not possible to do this in the compiler due to
problems with representation of such functions in the `.beam` files.
Fortunately, we can do this in the loader.
Simple evaluation shows that functions that don't capture the
enviornment consistute over 60% of all funs in the source code of
Erlang/OTP itself.
The only downside is that we lose a meningful value in the `pid` field
of the fun. The goal of this field, beyond debugging, was to be
able to identify the original node of a function. To be able to still do
this, the functions that are created in the loader are assigned the init
pid as the creator.
To solve issues with staryp, initially set the `erts_init_process_id`
to `ERTS_INVALID_PID` and skip the described optimisation if the value
is still uninitialised.

When matching on a literal map, the map is placed into the general
scratch register first. This is fine in isolation, but when the
key to be matched was in a Y register it would also be placed in
the scratch register, overwriting the map and crashing the
emulator.

This is a hack to make the "noshell" option work; kqueue can poll
these fds but will not report EV_EOF. This may be common to all
all pipes but we have no way to tell whether an fd is a pipe or
not.
