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

2011-02-03HALFWORD ETS relative termsSverker Eriksson
In halfword emulator, make ETS use a variant of the internal term format that uses relative offsets instead of absolute pointers. This will allow storage in high memory (>4G). Preprocessor macros (like list_val_rel(TERM,BASE)) are used to make normal (fullword) emulator almost completely unchanged while still reusing most of the code.
2011-01-31Remove hipe constants poolPaul Guyot
Hipe constants used to be allocated within a single, fixed-size pool for interaction with the garbage collector. However, the garbage collector no longer depends on constants being allocated within a single pool, and the fixed size of the pool both meant unnecessary allocations on most deployments and crashes on deployments requiring more constants. The code was simplified to directly invoke erts_alloc. Debugging and undocumented function hipe_bifs:show_literals/0 was removed (it returned true and output text to the console), and debugging and undocumented function hipe_bifs:constants_size/0 was rewritten with a global to count the size of allocated constants.
2011-01-29Fix several bugs related to hibernate/3 and HiPEPaul Guyot
This commit fixes four related bugs: - calling hibernate/3 using a dynamic call would fail with badarg as hibernate/3 as a BIF was not implemented. hibernate/3 is generally provided as a Beam instruction, and code is translated to use this instruction when loaded. - calling hibernate/3 from HiPE would fail with badarg because this would call the aforementioned BIF which was not implemented. - calling hibernate/3 with some HiPE-native garbage in the process heap would randomly crash at the next garbage collect. This bug only happened in a complex, yet reproduceable scenarios, where native code calls beam code that calls hibernate/3, and the process has some garbage when being hibernated and the process generates garbage when awaken. - when entering HiPE, the process current_function can be set and be inaccurate. The fix is three folded: - hibernate_3 BIF now actually works instead of throwing a badarg. While hibernate_3 BIF was (usually) not called from BEAM, it is called from HiPE. hibernate behaviour is very close to the scheduler and this is why it is implemented as an instruction in BEAM. The fix consists in doing the actual hibernation (through the now exported erts_hibernate function) and setting the process flag to TRAP as well as the process status to P_WAITING. On BIF epilogue in both BEAM and HiPE, this status is tested on TRAP and if set, the scheduler is invoked. The i_hibernate instruction and translation code is now redundant and could be deleted. - hibernation now also empties the HiPE native stack, with a new function hipe_empty_nstack provided by Mikael Pettersson. - when entering HiPE through hipe_mode_switch, p->current is cleared, as suggested by Mikael Pettersson. p->current normally hold a pointer to the {M,F,A} of the current function if it exists. When hibernating, it is set to {erlang,hibernate,3}, and all stdlib hibernate tests (gen_server_SUITE:hibernate/1, proc_lib_suite:hibernate/1, etc.) actually rely on this information. Clearing p->current fixes the tests and avoids the surprise one might have when querying the process info of a process that hibernated and woke up in a native function. Non-regression tests are provided, a test for the dynamic call as well as a Makefile-handled duplication of the hibernate_SUITE into hibernate_native_SUITE for the HiPE case.

code within the escript with the +native flag. You need an HiPE enabled emulator for this to work.

2011-01-18Lower the maximum arity from 256 to 255Björn Gustavsson
Historically, for no good reason, a function is allowed to have from 0 to 256 arguments. Thus, the number of arguments *almost* fits into a byte. HiPE only supports up to 255 arguments (because it assumes that the function arity fits into a single byte), and fixing that limitation would require ugly special-case handling. In Dialyzer, the arity type is defined to be a byte (i.e. 0..255). Since no-one uses functions with 256 arguments anyway, lower the limit to 255.
