2018-07-13Fix a rare crash when matching on literal mapsJohn Högberg
When matching on a literal map, the map is placed into the general scratch register first. This is fine in isolation, but when the key to be matched was in a Y register it would also be placed in the scratch register, overwriting the map and crashing the emulator.

2018-07-04Fix release notes for OTP-21.0.2John Högberg
The release notes generated in the README and notes.xml were out of sync, and notes.xml erroneously listed a fixed bug as open.
2018-07-03Use fallback pollset for stdin and friends when using kqueueJohn Högberg
This is a hack to make the "noshell" option work; kqueue can poll these fds but will not report EV_EOF. This may be common to all all pipes but we have no way to tell whether an fd is a pipe or not.

2018-06-28Fix a race condition when generating async operation idsJohn Högberg
The counter used for generating async operation ids was a plain int shared between all ports, which was incorrect but mostly worked fine since the ids only had to be unique on a per-port basis. However, some compilers (notably GCC 8.1.1) generated code that assumed that this value didn't change between reads. Using a shortened version of enq_async_w_tmo as an example: int id = async_ref++; op->id = id; //A return id; //B In GCC 7 and earlier, `async_ref` would be read once and assigned to `id` before being incremented, which kept the values at A and B consistent. In GCC 8, `async_ref` was read when assigned at A and read again at B, and then incremented, which made them inconsistent if we raced with another port. This commit fixes the issue by removing `async_ref` altogether and replacing it with a per-port counter which makes it impossible to race with someone else.
2018-06-27Fix internal compiler error for map_get/2Björn Gustavsson
Code such as that the following: Val = map_get(a, Map), Map#{a:=z} %Could be any map update would incorrectly cause an internal consistency check failure: Internal consistency check failed - please report this bug. Instruction: {put_map_exact,{f,0},{x,0},{x,0},1,{list,[{atom,a},{atom,z}]}} Error: {bad_type,{needed,map},{actual,term}}: Update beam_validator so that it understands that the second argument for map_get/2 is a map.
2018-06-27beam_type: Fix unsafe optimizationBjörn Gustavsson
beam_type assumed that the operand for the bs_context_to_binary instruction must be a binary. That is not correct; bs_context_to_binary accepts anything. Based on the incorrect assumption, beam_type would remove other test instructions. The bug was introduced in eee8655788d2, which was supposed to be just a refactoring commit. https://bugs.erlang.org/browse/ERL-655
2018-06-27Move to a dirty scheduler even when we have pending system tasksJohn Högberg
When a system task was enqueued on a process between being scheduled and the check altered in this commit, we'd run dirty code on a normal scheduler as the RUNNING_SYS flag wasn't set and we wouldn't migrate back. This change migrates us to a dirty scheduler instead, which will immediately bounce us back to a normal scheduler where RUNNING_SYS will be set appropriately. This is caught fairly reliably by process_SUITE:system_task_failed_enqueue on machines with a lot of cores.

2018-06-25Fix unsafe optimization when running beam_block the second timeBjörn Gustavsson
The compiler would crash when compiling code such as: serialize(#{tag := value, id := Id, domain := Domain}) -> [case Id of nil -> error(id({required, id})); _ -> <<10, 1:16/signed, Id:16/signed>> end, case Domain of nil -> error(id({required, domain})); _ -> <<8, 2:16/signed, Domain:32/signed>> end]. The crash would look like this: Function: serialize/1 t.erl: internal error in block2; crash reason: {badmatch,false} in function beam_utils:live_opt/4 (beam_utils.erl, line 861) in call from beam_utils:live_opt/1 (beam_utils.erl, line 285) in call from beam_block:function/2 (beam_block.erl, line 47) in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33) in call from beam_block:'-module/2-lc$^0/1-0-'/2 (beam_block.erl, line 33) in call from beam_block:module/2 (beam_block.erl, line 33) in call from compile:block2/2 (compile.erl, line 1358) in call from compile:'-internal_comp/5-anonymous-1-'/3 (compile.erl, line 349) The reason for the crash is an assertion failure caused by a previous unsafe optimization. Here is the code before the unsafe optimization: . . . {bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}. {bs_put_string,3,{string,[8,0,2]}}. {bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}. {move,{x,1},{x,0}}. {test_heap,4,1}. . . . beam_block:move_allocate/1 moved up the test_heap/2 instruction past the move/2 instruction, adjusting the number of live registers at the same time: . . . {bs_init2,{f,0},7,0,0,{field_flags,[]},{x,1}}. %% Only x1 is live now. {bs_put_string,3,{string,[8,0,2]}}. {bs_put_integer,{f,0},{integer,32},1,{field_flags,[signed,big]},{y,1}}. {test_heap,4,2}. %Unsafe. x0 is dead. {move,{x,1},{x,0}}. . . . This optimization is unsafe because the bs_init2 instruction killed x0. The bug is in beam_utils:anno_defs/1, which adds annotations indicating the registers that are defined at the beginning of each block. The annotation before the move/2 instruction incorrectly indicated that x0 was live. https://bugs.erlang.org/browse/ERL-650 https://github.com/elixir-lang/elixir/issues/7782
