Send may have failed, port exit with dist_entry cleaned up
and then new pending connection with queued messages.
|
|
When finalizing outgoing distribution messages
we transcode them into using tuple fallbacks if the
receiver does not support bitstrings and export-funs.
This can only happen if the message was first encoded toward
a pending connection when the receiver was unknown.
It's an optimistic approach optmimized for modern beam nodes,
that expect real bitstrings and funs (since <R13).
Only erl_interface/jinterface lack this support.

even when reds <= 1
Removed micro optimization for first fun variable
to make things simpler.
|

DFLAG_EXPORT_PTR_TAG and DFLAG_BIT_BINARIES
|
|
in order to call ei_publish() separately.
|
|
to avoid tuple fallbacks for export funs and bitstrings.
ToDo: Re-encode if receiver turn out to be erl_interface/jinterface.

The least bad behavior I think:
* We cannot return 'noconnect' as caller might already have enqueued
monitor/link that never triggers.
* We cannot block waiting for connection as that can ruin latency
when 'noconnect' is used to avoid blocking auto-connect
(see gen_server and gen_statem).
But there might be users getting more cases of bad latency
waiting for a pendig connection, instead of a fast 'noconnect'.

Removed distribution_SUITE:applied_monitor_node
as it seems to test apply of trapping BIF
and monitor_node does not trap anymore.
|
|
|
|
Break out from 'flags' into new dedicated 'connection_id'
just for simplicity.
Also changed flags to low bits
and that affected enif_binary_to_term.
|
|
as a preparation for async auto-connect requests.
|
|
and remove ugly encoding fallback as {fun, ...}
DFLAGS_NEW_FUN_TAGS has been supported by vm/erl_interface/jinterface
since R13 or even older.
Renamed test case obsolete_funs to term2bin_tuple_fallbacks
and removed test for {fun,...} fallback
and added missing test for bitstring fallback {Binary, Bits}.
|
|
Runs much faster now.
|
|
for set/get_internal_state calls.

Distribution flag DFLAG_UTF8_ATOMS is supported since R16
and mandatory since 20.0.

to handle "lookup without refc++" correctly
which was introduced in 4dcb2ae7810a507b701a30072b2f514cab7ebbdb.
When decrementing refc to zero (in try_delete or prepare_try_delete)
we must always wait thread progress to make sure no thread has done
lookup without refc++ and is just about to do refc++ and thereby revive
the DistEntry. That is, we wait for a potential other thread to either
do refc++ or drop its pointer to the DistEntry.
And if that other thread does refc++ (in erts_ref_dist_entry)
it must also do the extra refc++ for the scheduled pending delete.
