2011-03-04erts: Initialize register that may be referenced by garbage collectionBjörn Gustavsson
The call_fun() function in the BEAM emulator is supposed to to put the fun term in the x register following the actual arguments and environment for the fun. But if the fun is not loaded and a call to the error_handler:undefined_lambda/3 function is set up, the x(3) register will not be initialized. The lack of initialization is very unlikely to cause a problem in practice, because all of the following things must happen: 1) An unloaded fun must be called (i.e. the fun must have been received from another node or from a file or dets table). 2) The process must be scheduled out before the call to the error_handler:undefined_lambda/3 function can take place. 3) The process must be garbage collected before the process is scheduled in. 4) The x(3) register must contain a stale cons or box pointer that happens to point into the the heap of the currently executing process. (Because of the literal pool, the GC will never copy anything that is outside of the heap.) I was not able to write a test case that would force an emulator crash.

2011-02-23beam_emu: Remove unnecessary decrement of I in "case_end r"Björn Gustavsson
It is not necessary to decrement I, because an exception is about to be generated. Furthermore, I pointing *before* the instruction that caused the exception may cause problems in the future.
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.
2011-02-21Add patch from Per HedelandPatrik Nyblom
Per H @ Tail-f: The original code here had problems that possibly only occur if you abuse it for non-INET sockets, but anyway: a) If the getsockopt for SO_PRIORITY or IP_TOS failed, the actual requested setsockopt was never even attempted. b) If {get,set}sockopt for one of IP_TOS and SO_PRIORITY failed, but ditto for the other worked and that was actually the requested option, failure was still reported to erlang.

* 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
