Use '+hpds size' to set initial process dictionary size for spawned processes.
|
|
|
|
This will also fix a bug in term_to_binary
treating full nodes as tuples and emiting LIST_EXT for leafs.
|
|
Must save hamt_list in context.

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).

* sverk/hamt-overestimate/OTP-12585:
erts: Add test map_SUITE:t_hashmap_balance
erts: Fix hashmap overestimation
erts: Silence valgrind warning in nif_SUITE.c

Old overestimation assumed an average of k/3 nodes.
This can be bad for large maps (with tight standard deviations)
as the average vary between 0.3*k and up to almost 0.4*k.

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.

saved and later restored.

Adding ERTS_SWORD_MAX to a pointer does not work
as a way to disable a bound check.
Remove the hp_end from ErtsHeapFactory as it isn't really used anyway.

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.
