Prevent inconsistent node lists
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.

Fix incoming suspend monitor down
|
|
An incoming suspend monitor down wasn't handled correct when the
local monitor half had been removed with an emulator crash as result.

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

OTP-14282
'can not' should mostly be 'cannot'
|
|
I did not find any legitimate use of "can not", however skipped
changing e.g RFCs archived in the source tree.

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.

Move to a dirty scheduler even when we have pending system tasks
|
|
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.

The fail state wasn't re-checked in the state change loop; only
the FREE state was checked. In addition to that, we would leave
the task in the queue when bailing out which could lead to a
double-free.
This commit backports active_sys_enqueue from master to make it
easier to merge onwards.

epmd: allow alternative to dns resolving for nodename
|

This makes it possible to create a custom integration with a
key-value store for example. The key would then point to the
actual address. You would have to write your own epmd module
to make use of that feature.
