* sverker/clarify_nif_resource_doc: clarify NIF resource object deallocation documentation
2011-03-09clarify NIF resource object deallocation documentationSteve Vinoski
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.

2011-02-21Allow unexpected driver input event in driver_SUITE:smp_selectSverker Eriksson
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) Conflicts: lib/compiler/test/compile_SUITE.erl OTP-9065
2011-02-18Add dependencies Makefile generation to erlc(1) and compile(3)Jean-Sébastien Pédron
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. More informations at: http://wiki.github.com/dumbbell/otp/dependencies-makefile

2010-11-22ETS 'compressed' option.Sverker Eriksson
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").

2010-11-02Be less eager to set dist entry in busy stateRickard Green
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
2010-11-02Add flag-based setting for the distribution buffer busy limitScott Lystig Fritchie
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.

The CPU topology is now automatically detected on Windows systems with less than 33 logical processors. The runtime system will now, also on Windows, by default bind schedulers to logical processors using the 'default_bind' bind type if the amount of schedulers is at least equal to the amount of logical processors configured, binding of schedulers is supported, and a CPU topology is available at startup.
