2017-02-20Ensure prim_eval:'receive' wont clobber def_arg_reg[0]Rickard Green
def_arg_reg[0] is used for storage of timeout instruction when a 'receive after' is executed. When a process was scheduled out inside prim_eval:'receive'/0 due to a function call, def_arg_reg[0] was overwritten due to storage of live registers. prim_eval:'receive'/2 now calls arg_reg_alloc/0 which bumps all reductions and then calls arg_reg_alloc/7 which will cause an allocation of a new arg_reg array since def_arg_reg only can hold 6 values. This ensures that the timeout instruction in def_arg_reg[0] used for the timeout wont be overwritten.
2017-02-17Teach make_preload to handle the new 'AtU8' chunkBjörn Gustavsson
26b59dfe67 introduced the new 'AtU8' chunk to support Unicode atoms. make_preload strips the pre-loaded BEAM files so that they only contain essential chunks. It expects to find the old 'Atom' chunk. Teach make_preload to read the new 'AtU8' chunk instead of the old chunk. Also produce a nice error message if someone by mistake compiles the pre-loaded modules with an OTP 19 compiler.

2016-11-05Fix performance bug in erl_prim_loader:get_modules/{2,3}Björn Gustavsson
The erl_prim_loader:get_modules/{2,3} functions were introduced in cd283583f8. Unfortunately, while the functions worked correctly, there was a bug in that many garbage maessages would be sent to the erl_prim_loader process. The number of extra messages depended on both the length of the code path and of the number of modules that were fetched. The messages were ignored and ultimately discarded, causing no harm except for a performance degradation and increase of the heap size for the erl_prim_loader process. The following functions were hit by the performance bug: code:atomic_load/1 code:ensure_modules_loaded/1 code:prepare_loading/1

Add system_info(atom_limit) to provide a way to retrieve the maximum number of atoms allowed. Add tests and documentation for it too. Also split system_info_SUITE:start_node/2 to start_node_ets/2 and start_node_atm/2 to avoid code duplication.

2016-09-14Don't leak old code when loading a modules with an on_load functionBjörn Gustavsson
Normally, calling code:delete/1 before re-loading the code for a module is unnecessary but causes no problem. But there will be be problems if the new code has an on_load function. Code with an on_load function will always be loaded as old code to allowed it to be easily purged if the on_load function would fail. If the on_load function succeeds, the old and current code will be swapped. So in the scenario where code:delete/1 has been called explicitly, there is old code but no current code. Loading code with an on_load function will cause the reference to the old code to be overwritten. That will at best cause a memory leak, and at worst an emulator crash (especially if NIFs are involved). To avoid that situation, we will put the code with the on_load function in a special, third slot in Module. ERL-240

2016-09-05Implement the new ceil/1 and floor/1 guard BIFsBjörn Gustavsson
Implement as ceil/1 and floor/1 as new guard BIFs (essentially part of Erlang language). They are guard BIFs because trunc/1 is a guard BIF. It would be strange to have trunc/1 as a part of the language, but not ceil/1 and floor/1.

2016-08-31Avoid selective receive in code-purger processRickard Green
The code purger process handles vast amounts of messages when there are lots of processes alive. A single message in the message queue that does not match will in such cases cause lots of extra work. The code purger process now always picks the first message in the message queue, and by this avoid this extra work.
