2010-11-22erl_types: Fix pretty rare crashes and an infinite loopKostis Sagonas
- Fixed pretty rare crash when taking the infimum of two tuple_sets (initial fix by Kostis Sagonas but then a better fix was provided by Stavros Aronis and this is the one adopted). - Fixed pretty rare crash when using parameterized types containing unbound variables (thanks to Nicolas Trangez for reporting it). - Fixed pretty rare infinite loop when refining the types of an SCC whose functions all returned none() (thanks to Stavros Aronis).

2010-11-18Generalize reader groupsRickard Green
Reader groups have been generalized to cpu groups which can be used for implementing reader groups, but also for implementing other functionality in the future.

When the runtime system had fewer schedulers than logical processors, the system could get an unnecessarily large amount reader groups.

2010-11-12Fix manifest filesDan Gudmundsson
It seems windows have updated manifest files in VS2010 which caused the erlang programs to contain duplicate requestedExecutionLevel entries, which is not allowed. This patch removes the microsoft entry, before adding our own which is known to work with XP and Vista.

2010-11-09Fix building error of SCTP in FreeBSD 7.1 and laterKenji Rikitake
This patch fixes building error of SCTP in FreeBSD 7.1 and later. See http://www.erlang.org/cgi-bin/ezmlm-cgi?2:mss:1257:200904:hppnfialjjdlgecdiehe for the details. R13A patch for solving a compilation error when building erts/emulator/drivers/common/inet_drv.c by Kenji Rikitake 12-APR-2009 Symptom solved by this patch: When building R13A in FreeBSD 7.1-RELEASE, the compiler flag HAVE_STRUCT_SCTP_PADDRPARAMS_SPP_SACKDELAY is NOT enabled. Some code in erts/emulator/drivers/common/inet_drv.c incorrectly assumes HAVE_STRUCT_SCTP_PADDRPARAMS_SPP_SACKDELAY is always true when HAVE_STRUCT_SCTP_PADDRPARAMS_SPP_FLAGS is true in config.h. This assumption causes a compilation error.

2010-11-04Fix badly formed Dets file after initializationHans Bolinder
If a Dets table with fewer slots than keys was opened and then closed after just a lookup, the contents were no longer well-formed. This bug has been fixed. (Thanks to Matthew Evans.)
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.
