* maint: Improve trapping in lists:reverse/2 Fix unsafe use of lists:reverse/1
2018-09-13Improve trapping in lists:reverse/2John Högberg
If the process had more free space than reductions it could run a lot longer than it was supposed to. It didn't honor the number of reductions going in either, nor did it bump reductions when returning its result or erroring out. This commit also removes this function from a work function in scheduler_SUITE as it's extremely sensitive to the number of reductions spent in the test, causing equal_and_high_with_part_time_max to fail on some machines.

2018-09-05Prevent inconsistent node listsRickard Green
If net_kernel "forgets" to abort a connection (as it currently might), the garbage collection of a distribution entry could cause node lists to enter an inconsistent state.

An incoming suspend monitor down wasn't handled correct when the local monitor half had been removed with an emulator crash as result.

2018-08-03erts: Fix seq_trace to not clear token for system messagesLukas Larsson
A lot of erts internal messages used behind APIs to create non-blocking calls, e.g. port_command, would cause the seq_trace token to be cleared from the caller when it should not. This commit fixes that and adds asserts that makes sure that all messages sent have to correct token set. Fixes: ERL-602

Optimise creation of anonymous functions
2018-07-17Optimise creation of anonymous functionsMichał Muskała
This introduces a similar optimisation for normal funs to what was introduced for external funs in #1725. It is possible to allocate the fun as a literal, if it does not capture the environment (i.e. it does not close over any variables). Unfortunately it's not possible to do this in the compiler due to problems with representation of such functions in the `.beam` files. Fortunately, we can do this in the loader. Simple evaluation shows that functions that don't capture the enviornment consistute over 60% of all funs in the source code of Erlang/OTP itself. The only downside is that we lose a meningful value in the `pid` field of the fun. The goal of this field, beyond debugging, was to be able to identify the original node of a function. To be able to still do this, the functions that are created in the loader are assigned the init pid as the creator. To solve issues with staryp, initially set the `erts_init_process_id` to `ERTS_INVALID_PID` and skip the described optimisation if the value is still uninitialised.

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.

2018-07-03Use 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.

2018-06-14Don't enqueue system tasks if target process is in fail_stateJohn Högberg
The fail state wasn't re-checked in the state change loop; only the FREE state was checked. In addition to that, we would leave the task in the queue when bailing out which could lead to a double-free. This commit backports active_sys_enqueue from master to make it easier to merge onwards.

This makes it possible to create a custom integration with a key-value store for example. The key would then point to the actual address. You would have to write your own epmd module to make use of that feature.
