Create a clone of map_SUITE named map_no_opt_SUITE to ensure that
the loader can cope with unoptimized map instructions.

Erlang treats positive and negative zero as equal, meaning,
true = 0.0 =:= 0.0/-1
However, Erlangs hash functions: hash, phash and phash2 did not
reflect this behaviour. Meaning, the hash values produced by
the different hash functions would not be identical for positive
and negative zero.
This commit ensures that hash value of positive zero is always
produced regardless of the signedness of the zero float, i.e.
true = erlang:phash2(0.0) =:= erlang:phash2(0.0/-1)

Repeated keys will shrink map to a flatmap if the number of pairs drops below the limit.

This will also fix a bug in term_to_binary
treating full nodes as tuples and emiting LIST_EXT for leafs.
|
|
Comparison of exact terms could cause faulty term tests.
This was caused by a faulty (too small) internal type.
Symptom:
-1 = erts_internal:cmp_term(2147483648,0). %% wrong
Correct:
1 = erts_internal:cmp_term(2147483648,0).

The old time API is based on erlang:now/0. The major issue with
erlang:now/0 is that it was intended to be used for so many
unrelated things. This tied these unrelated operations together
and unnecessarily caused performance, scalability as well as
accuracy, and precision issues for operations that do not need
to have such issues. The new API spreads different functionality
over multiple functions in order to improve on this.
The new API consists of a number of new BIFs:
- erlang:convert_time_unit/3
- erlang:monotonic_time/0
- erlang:monotonic_time/1
- erlang:system_time/0
- erlang:system_time/1
- erlang:time_offset/0
- erlang:time_offset/1
- erlang:timestamp/0
- erlang:unique_integer/0
- erlang:unique_integer/1
- os:system_time/0
- os:system_time/1
and a number of extensions of existing BIFs:
- erlang:monitor(time_offset, clock_service)
- erlang:system_flag(time_offset, finalize)
- erlang:system_info(os_monotonic_time_source)
- erlang:system_info(time_offset)
- erlang:system_info(time_warp_mode)
- erlang:system_info(time_correction)
- erlang:system_info(start_time)
See the "Time and Time Correction in Erlang" chapter of the
ERTS User's Guide for more information.

* nox/fix-port_info-race:
Fix a race condition when calling port_info/1
OTP-12587
|

Hmm, seems like gcc (4.4.3 at least) can switch the order
of an &&-expression and do the last condition first if it
think it's more efficient (and without side effects I hope).
Which led to valgrind complaining about 'prev_ret' being used
uninitialized in this case.

This variable hold the values returned by erlang:port_info/1 and
shouldn't be static.

Add a check to enif_make_double to see if its double argument is
infinity or NaN, returning a badarg exception if it is. Change the
erl_nif documentation to specify that enif_make_double returns a
badarg exception if its double argument is either infinity or NaN. Add
tests to nif_SUITE for this change.
Add checks to the enif_make* functions for atoms to prevent the
creation of atoms whose name lengths are greater than the allowed
maximum atom length. The enif_make_atom and enif_make_atom_len
functions now return a badarg exception if the input string is too
long. The enif_make_existing_atom and enif_make_existing_atom_len
functions return false if the input string is too long. Change the
erl_nif documentation to reflect the changes to these functions. Add
tests to nif_SUITE for these changes.
Add a field to ErlNifEnv to track that a NIF has raised an exception
via enif_make_badarg. If a NIF calls enif_make_badarg but then ignores
its return value and instead tries to return a non-exception term as
its return value, the runtime still raises a badarg. This is needed to
prevent enif_make_badarg values resulting from calls to
enif_make_double, enif_make_atom, or enif_make_atom_len from being
erroneously stored within other terms and returned from a NIF. Calling
enif_make_badarg but not returning its return value has been
documented as being illegal ever since enif_make_badarg was added, but
the runtime has not enforced it until now. Add tests for regular and
dirty NIFs to ensure that calls to enif_make_badarg result in badarg
exceptions even if a NIF fails to return the result of
enif_make_badarg as its return value. Add documentation to
enif_make_badarg to specify that calling it raises a badarg even if a
NIF ignores its return value.
