into maint-20 * john/erts/fix-process-schedule-after-free/OTP-15067/ERL-573: Don't enqueue system tasks if target process is in fail_state Fix erroneous schedule of freed/exiting processes Fix deadlock in run queue evacuation Fix memory leak of processes that died in the run queue
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.

2018-02-15badarg on iolist_to_binary(Bitstring)John Högberg
When supplied without an enclosing list, bitstrings were returned as-is instead of badarging.
2018-02-15Handle unaligned binaries in enif_inspect_iovecJohn Högberg
2018-02-15Handle unaligned binaries in erlang:iolist_to_iovec/1John Högberg
A binary is a binary as long as its size in bits is evenly divisible by 8, regardless of whether it has a bit offset or not.
2018-02-15badarg on iolist_to_iovec(Bitstring)John Högberg
When supplied without an enclosing list, bitstrings were silently truncated to [] instead of badarging.
2018-02-15Test badarg when an improper list tail contains a bitstringJohn Högberg
This has always worked but we lacked test coverage for it.
2018-02-13Use smaller inputs in iovec testsJohn Högberg
Huge inputs weren't particularly useful and took forever to run, so this commit winds it down to a more sane level that still causes lots of yielding.

2018-01-15erts: Fix float_to_list(F, [{decimals,D}]).Sverker Eriksson
Example symptom: 1> float_to_list(0.145, [{decimals,1}]). "0.2" There were two problems in sys_double_to_chars_fast 1. Most serious was adding 0.55555555 / (10^D) instead of 0.5 / (10^D) which imposed a 5.5% risk of a faulty rounding up. 2. Using fixpoint for frac_part which lost significant bits if F < 0.5

2018-01-03Fail if ':' is passed to binary_to_integer/2Frank Hunleth
Before: 1> binary_to_integer(<<":">>, 16). 3 After: 1> binary_to_integer(<<":">>, 16). ** exception error: bad argument in function binary_to_integer/2 called as binary_to_integer(<<":">>,16) Prior to this change, both list_to_integer/2 and binary_to_integer/2 would convert strings with values between ASCII '9' up to '0'+base for base > 10. For example, when converting in base 16, you could pass ':', ';', '<', '=', '>', and '?' without getting an exception. This was due to a missing check in c2int_is_invalid_char(). This change adds the missing check and a regression test for passing ':'. It also simplifies the code and tightens up an out-of-bounds check to make it off-by-one rather than off-by-two.

2017-11-24Fix purging of modules with "fake literals"Björn Gustavsson
When compiling Erlang source code, the literal area for the module can only contain data types that have a literal syntax. However, it is possible to sneak in other data types (such as references) in the literal pool by compiling from abstract or assembly code. Those "fake literals" would work fine, but would crash the runtime system when the module containing the literals was purged. Although fake literals are not officially supported, the runtime should not crash when attempting to use them. Therefore, fix the garbage collection of literals and releasing of literal areas. https://bugs.erlang.org/browse/ERL-508

2017-10-09erts: Fix caller trace for apply bifsLukas Larsson
Bifs that are called through the export entry using i_call_last could have their cp set to return_trace, just like any other call. So we have to unwind the trace stack to get the correct cp. Not doing this creates a lot of issues for fprof.

2017-09-22Correctly append sub-binaries in iolist_to_iovecJohn Högberg
The byte_offset of sub-binaries wasn't taken into account for ProcBins, subtly ruining the results. The test suite didn't catch it since it didn't check for sub-binaries in particular, and only checked for equality between variations -- not whether the output was equal to the input.
