Many heap fragments do no longer make the GC slow.
Even worse, we are not guaranteed that a yield will provoke a GC
removing the fragments, which might lead to a one-yield-per-bucket
scenario if the heap fragment(s) still remains after each yield.

Test case can not make assumptions on how many chunks will delivered
from the underlaying TCP stream.
Some code commented out that should be used in some form to create
a new test case. There might be other issues than the one fixed in
the previous commit.

Instead rely on gnu make's pre-defined RM variable which should
equal 'rm -f'

Spread a server over three nodes, one of which terminates a peer
connection, the other two to handle requests. Terminate transport on one
of the server nodes and ensure that answers come only from the other
two.

If the Session-Id optional value to node() mapping fails then hash
Session-Id to a node by default, instead of selecting the local node as
in the parent commit. The previous behaviour is configurable by setting
default = local in an options map.
Nodes make themselves part of the pool from which nodes are selected by
calling diameter_dist:attach/1 with the list of service names they are
willing to handle requests for, the local node being selected in the
absence of any attached nodes. The original idea was to base the node
pool on share_peers and/or use_shared_peers configuration, but that
configuration determines where outgoing requests can be sent, while
route_session/2 deals with incoming requests, so it's not obvious that
conflating the two is a good thing. (Also because
share_peers/use_shared_peers can be used in different ways; the former
could have been skipped entirely.)
The hashing effectively places nodes on a circle, a hashed Session-Id
being mapped to the nearest predecessor node (clockwise). Nodes are
rehashed with each Session-Id (with the id as salt) for a more even
distribution, at the cost of performance, although how high the cost or
how even the distribution has yet to be tested. Obviously, the larger
the number of attached nodes, the higher the cost. Adding/removing an
attached node only affects session ids that hash in the interval between
the added/removed node and its successor (hence consistent hashing).
Options are tweaked slightly compared to the parent commit, and it is
now possible to restrict the optional value mapping to specific Diameter
identities, to avoid mapping an id that was generated at the peer when
the peer is also implemented with the diameter application.
Note that diameter_dist is not yet an officially documented interface,
so could change. Documentation is in the module itself.

To be able to restrict how many AVPs will be examined (from the front of
a message) when looking for Session-Id, and to decide what to do with if
the AVP isn't found. Options are specified as a map of the following
form.
#{search => non_neg_integer(),
default => discard | mfa(),
dispatch => list() | mfa()}
The search member says how many AVPs to examine at most, from the front
of the message. If the optional value of a Session-Id is not the name of
a connected node then the default member determines what to do with the
request, handle it locally (the default), discard it, or invoke an MFA
on the Session-Id | false (if none was found) and diameter_packet record
to return a node() | false; if the latter then the request is discarded.
If a node is identified then the dispatch MFA is invoked on the node and
the request MFA (as three arguments), a list Opts being equivalent to
the MFA {erlang, spawn_opt, [Opts]}, and the default being the empty
list.
Integer- or list-valued options are equivalent to the corresponding map
with a single value.
Limiting the search is to avoid searching messages containing many AVPs
for a Session-Id that is known to occur near the header, since section
8.8 of RFC 6733 says this:
When present, the Session-Id SHOULD appear immediately
following the Diameter header (see Section 3).
There's no guarantee, but in practice it may well be known that peers
are respecting the RFC, and in that case limiting the search is a
defense against searching messages from a malicious peer unnecessarily.
The search is unlimited by default.
A default is only used when a search fails to locate a Session-Id, and
can be to discard the message, or have a node() or false be returned
from an MFA applied to the diameter_packet in question. The local node
is chosen by default.

That is, of functions that can be configured as spawn_opt MFAs in
transport configuration.
This commits adds the spawn_local described in the parent commit, and a
route_session that assumes that the local node initiates all sessions
with Session-Id returned by diameter:session_id/1, and handles incoming
requests on the node on which the id in question was returned,
diameter:session_id/1 using node() as optional value in the Session-Id
format.
|

The possibility of configuring an MFA as spawn_opt was added in commit
fd285079, the callback being passed an arity-0 fun to be applied in an
appropriate handler process. Replace the fun by a tuple to be passed to
diameter_traffic:request/1, to avoid passing funs between nodes when
handler processes are remote.
A list-valued spawn_opt is now equivalent to the following configured as
{spawn_opt, {Mod, spawn_local, [Opts]}}.
spawn_local(ReqT, Opts) ->
spawn_opt(diameter_traffic, request, [ReqT], Opts).
ReqT is passed by diameter and contains information that the callback
may want to decide where to handle the request in question (which wasn't
accessible with a fun), but this information isn't exposed in a
documented way. The intention is instead to add an own callback
implementation to make use of the information.
Note that application lookup now takes place in the watchdog process in
both the list-valued (or no configuration) and mfa-valued cases. Whether
this is good, bad, or (probably) inconsequential remains to be seen.

This is the {diameter, ack} message from a transport process to its
parent that requests that every Diameter request passed to the parent be
matched by a incoming send message, the atom false replacing a message()
in the case that the request is unanswered, allowing the transport to
keep track of the number of outstanding requests.
These were added in commit ca09cf7b, and are used to implement the
message_cb config in diameter_tcp/sctp, documented in commit cefcaa5c.
This commit documents the interface, to make it available to other
transport implementations.

OTP-15602
It is allowed to set file modes for the handler to use when opening
its log file. The given modes were earlier accepted without any
checks, which could make the handler behave unexpectedly. This commit
makes sure that
* if none of write, append or exclusive is given, then append is added
* if raw is not given, it is added
* if delayed_write or {delayed_write,_,_} is not given, then
delayed_write is added

Fix install phase in build system
|
|
Change code to not send a message to itself as this allows other
messages to come in between. A change in TLS code made this scenario
more likely to happen, and the symptom is that the ftp:chunk_recv/1
function hangs.

|
|
|
Avoid traversing all of the list/string when only part of it will be
used. An explicit check that the list is flat is needed since
string:slice() accepts deep lists and more.

- Install of (mainly) documentation caused rebuild and

previously had been built. Also otp_patch_apply
modified the source tree when updating documentation.
This messed up the installation if installation was
performed by another user than the user that originally
built the system which not is an uncommon scenario.
- Some documentation was installed by copying files
instead of installing the files which caused faulty
access rights on files.
- The documentation was not properly updated when

Add application:set_env/1 and application:set_env/2
OTP-15642
|
|
It is equivalent to calling application:set_env/4 on
each application individually, except it is more efficient.
When given duplicate apps or duplicate keys, set_env/1
and set_env/2 will warn. The warning will also be emitted
during boot:
$ erl -config dupkeys.config -s erlang halt
2019-02-27 11:16:02.653100 application: kernel; duplicate parameter: key1
=WARNING REPORT==== 27-Feb-2019::11:16:02.653100 ===
application: kernel; duplicate parameter: key1
$ erl -config dupapps.config -s erlang halt
2019-02-27 11:16:02.653100 duplicate application config: kernel
=WARNING REPORT==== 27-Feb-2019::11:16:02.653100 ===
duplicate application config: kernel
Prior to this patch, the behaviour was unspecified,
and duplicate keys and duplicate apps would behave
different depending on the amount of config, the name
of the config files, and how those configs would be
listed. The goal is to raise an error in the future.
