* 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

2010-12-02Stop using uncertain flags for getaddrinfo()Raimo Niskanen
The AI_V4MAPPED flag is falling out of grace in modern IPv6 stacks, for security reasons, e.g. FreeBSD do not document it any longer. The AI_ADDRCONFIG flag have got unclear semantics on the same OS.

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.

* 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.

2010-10-07Incorporate Michael Santos patch for cerl and gdb via emacsPatrik Nyblom
Michael Santos supplied a very nice patch that did set the annotation level correctly for gdb when run from cerl in emacs. The patch adds --annotate=3 to the gdb command line, which makes emacs parse the gdb output correctly, making the right source code be loaded in the emacs buffer. While integrating it, I removed my faulty code trying to do the same with hacky elisp commands. Michaels way is the right way to do it. Thanks!
2010-10-06Added win32 large address aware link optionBlaine Whittle
This link option just sets a flag in the binary and doesn't change OS compatibility. This allows the Erlang VM to use up to 3 gigs of address space instead of the default of 2 gigs.

2010-09-29Add corrected support for Solaris PTYs to run_erlRyan Tilder
Two related but slightly separate issues: run_erl doesn't support Solaris's /dev/ptmx device and run_erl didn't load the necessary STREAMS modules so that to_erl can provide terminal echo of keyboard input. This patch adds ifdef'd support for Solaris and derivatives to open /dev/ptmx directly since adding the C99 defines to CFLAGS breaks all kinds of other things in the build. It also adds ifdef'd ioctl calls to load the necessary STREAMS modules to permit termios to work.

While attempting to debug odd terminal echo issues on Solaris, I noticed that run_erl.c will fail to compile due to a typo causing a syntax error.

2010-08-10Merge branch 'rickard/ethread-rewrite/OTP-8544' into devRickard Green
* rickard/ethread-rewrite/OTP-8544: Rewrite ethread library
2010-08-10Rewrite ethread libraryRickard Green
Large parts of the ethread library have been rewritten. The ethread library is an Erlang runtime system internal, portable thread library used by the runtime system itself. Most notable improvement is a reader optimized rwlock implementation which dramatically improve the performance of read-lock/read-unlock operations on multi processor systems by avoiding ping-ponging of the rwlock cache lines. The reader optimized rwlock implementation is used by miscellaneous rwlocks in the runtime system that are known to be read-locked frequently, and can be enabled on ETS tables by passing the `{read_concurrency, true}' option upon table creation. See the documentation of `ets:new/2' for more information. The ethread library can now also use the libatomic_ops library for atomic memory accesses. This makes it possible for the Erlang runtime system to utilize optimized atomic operations on more platforms than before. Use the `--with-libatomic_ops=PATH' configure command line argument when specifying where the libatomic_ops installation is located. The libatomic_ops library can be downloaded from: http://www.hpl.hp.com/research/linux/atomic_ops/ The changed API of the ethread library has also caused modifications in the Erlang runtime system. Preparations for the to come "delayed deallocation" feature has also been done since it depends on the ethread library. Note: When building for x86, the ethread library will now use instructions that first appeared on the pentium 4 processor. If you want the runtime system to be compatible with older processors (back to 486) you need to pass the `--enable-ethread-pre-pentium4-compatibility' configure command line argument when configuring the system.
