2012-08-17Relocate bodies of DTrace probes to the statically-linked VM.Scott Lystig Fritchie
Due to various operating systems (in both the DTrace and SystemTap worlds) not fully supporting DTrace probes (or SystemTap-compatibility mode probes) in shared libraries, we relocate those probes to the statically-linked virtual machine. This could be seen as pollution of the pristine VM by a (yet) experimental feature. However: 1. This code can be eliminated completely by the C preprocessor. 2. Leaving the probes in the dyntrace NIF shared library simply does not work correctly on too many platforms. *Many* thanks to Macneil Shonle at Basho for assisting when my RSI-injured fingers gave out. Tested on: * CentOS 5, SystemTap 1.3 * Solaris 10 (note) * Solaris 11 * OpenIndiana 151 * SmartOS 20120809T221258Z * FreeBSD 9.0-RELEASE (note) I had hoped to be able to test CentOS 6 + SystemTap 1.7, but the details of dealing with all dependencies for a 2.6.32-279.5.1.el6.x86_64 kernel are too time consuming right now. (note: Solaris 10 and FreeBSD 9.0-RELEASE can take a long time to compile)

Change the module-level docs to give complete step-by-step instructions for using the `dyntrace:p()` trace function. Also, remove the unused `scaff/0` function.

2011-11-13Optimize memory allocationRickard Green
A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.

2011-10-21Flush trace file driver before stopping dbgSiri Hansen
Earlier dbg:stop only did erlang:trace_delivered and did not flush the trace file driver. Therefore there could still be trace messages that were delivered to the driver (guaranteed by erlang:trace_delivered) but not yet written to the file. This commit adds this flushing on each node before the dbg process terminates.

2011-08-08*/c_src/Makefile*: Support parallel makeBjörn Gustavsson
Create directories first, not within implicit rules. If two 'install' instances runs at the same time attempting to create a directory, one of them may fail with an "File exists" error. I tried to use order-only prerequisites to create the directories, but run into two problems: First, order-only prerequisites are only implemented in Make 3.80 and later. Second, on a computer running Solaris/Intel 2.8 (with Make 3.80), order-only prerequisites seemed to work like ordinary prerequisites, causing targets to be re-built if the timestamp for the directory changed. Therefore, using a shell command to run mkdir seems to be the more portable solution.
2011-08-03Add two additional built-in trace patterns, c and cxLukas Larsson
c means [{'_',[],[{message,{caller}}]}] cx means [{'_',[],[{exception_trace},{message,{caller}}]}]
