* sverker/clarify_nif_resource_doc:
clarify NIF resource object deallocation documentation
|
|
In the erl_nif documentation, clarify how and when NIF resource
objects can be deallocated. Specifically, add focus for the case of
calling enif_release_resource immediately after obtaining a resource
term from enif_make_resource, since this is likely to be a common
approach NIFs use to manage resources.
Also fix a couple misspellings in the erl_nif documentation.

* lukas/stdlib/native_escript/OTP-9076:
Update escrips to allow the -n or -compile(native) flag, which compiles the code within the escript with the +native flag. You need an HiPE enabled emulator for this to work.

epoll on Linux has been seen to sometimes trigger unexpected
events. Most of the time these events are filtered by erl_check_io,
but may slip up to the driver in cases when fd's are reused.
Also made clear in driver docs that spurious events may happen.

* jp/dependencies_makefile:
Add dependencies Makefile generation to erlc(1) and compile(3)

This is useful when a project is built with Makefiles and erlc(1)
instead of EMakefiles. Tracking dependencies by hand is error-prone and
it becomes painful when using external application headers like EUnit's
one.
A dependencies Makefile will look like this:
module.beam: module.erl \
/usr/local/lib/erlang/lib/eunit-2.1.4/include/eunit.hrl \
header.hrl
When included in the main Makefile, 'module' will be recompiled only
when needed.
GCC offers the same feature and new erlc(1) options are compatible with
it.

Clarify that specifying "-noinput" is unnecessary if the "-detached"
flag is given.

enif_realloc_binary return int
enif_alloc/enif_free does not accept env as first argument.
enif_send return int
enif_self in alphabetic order

The compressed format is using a slighty modified variant of the extern format
(term_to_binary). To not worsen key lookup's too much, the top tuple itself
and the key element are not compressed. Table objects with only immediate
non-key elements will therefor not gain anything (but actually consume one
extra word for "alloc_size").

Be less eager to set dist entry in busy state
|
|
* sverker/doc-fixes/OTP-8880:
Documentation update to ETS and drivers
|
|
The runtime system is now less eager to suspend
processes sending messages over the distribution. The
default value of the distribution buffer busy limit
has also been increased from 128 KB to 1 MB. This in
order to improve throughput.

* sf/erts_de_busy_limit:
Add flag-based setting for the distribution buffer busy limit

Id: OTP-8912
This patch creates a new family of flags with the "+z" prefix. It
further creates a new configuration option called "dbbl" (which is the
first letter of the name dist_buf_busy_limit). Example usage of this
flag would be "+zdbbl 1048576".
This patch creates an adjustable buffer limit for the amount of data
that may be buffered by the erlang distribution code (in dist.c
specifically). Before this patch, this hard-coded constant was used:
#define ERTS_DE_BUSY_LIMIT (128*1024)
When large binaries are transmitted between nodes (or simply a lot of
medium-sized binaries), it is very easy to hit the old 128KB limit.
Processes that use the erlang:system_monitor() BIF to monitor system
events can be spammed by {monitor, busy_dist_port, ...} message tuples
at rates of tens to even hundreds of messages/second.
A larger buffer limit will allow processes to buffer more outgoing
messages over the distribution. When the buffer limit has been
reached, sending processes will be suspended until the buffer size has
shrunk. The buffer limit is per distribution channel. A higher limit
will give lower latency and higher throughput at the expense of
higher memory usage.
A variation of this patch has been in commercial production use in at
least two companies that the author is aware of. Larger buffer values
can reduce the number of {monitor, busy_dist_port, ...} system
messages drastically, lower overall messaging latencies, and prevent
false timeouts and 'nodedown' messages in extremely busy Mnesia systems.
Test suite: there are two tests:
a. In erlexec_SUITE.erl to test basic set & get of the value
b. In distribution_SUITE.erl, to verify that setting +zdbbl very
low will actually change behavior.

State more clearly that ETS functions will throw badarg if calling
process lacks access right. And that driver stop callback should free
memory allocted by start.

The scheduler wakeup threshold is now possible to adjust at system boot.
For more information see the `+swt' command line argument of `erl'.

Added erlang:system_info(build_type) which makes it
easier to chose drivers, NIF libraries, etc based
on build type of the runtime system.
