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.

Fix rounding bug in float_to_list/2

* fhunleth/binary_to_integer_chec/PR-1671/OTP-14879:
Fail if ':' is passed to binary_to_integer/2
|

* maint:
stdlib: Handle Unicode when formatting stacktraces
|
|
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

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.

putenv(3) and friends aren't thread-safe regardless of how you slice
it; a global lock around all environment operations (like before)
keeps things safe as far as our own operations go, but we have
absolutely no control over what libc or a library dragged in by a
driver/NIF does -- they're free to call getenv(3) or putenv(3)
without honoring our lock.
This commit solves this by setting up an "emulated" environment which
can't be touched without going through our interfaces. Third-party
libraries can still shoot themselves in the foot but benign uses of
os:putenv/2 will no longer risk crashing the emulator.

It crashed due to recursive calls to alloc_util
in carrier initialization test callback.

to mix it up with some realloc calls.

Symptom: "Closing pipe in state Waiting. Event lost?"
Snake oil:
Do erlang:yield() instead of busy spinning in "Waiting" state.

Add syntax in try/catch to retrieve the stacktrace directly

There doesn't seem to be any science behind the long delays, and
the (newly introduced) dry run forces us to eat them twice, so
they've been shortened to more reasonable values.
|
|
Code loading is done through dirty IO now, causing the
dirty_scheduler_exit tests to fail as they block their own progress
by invoking erts_debug:dirty_io(wait, _); the spawned processes
will exit normally before we have a chance to kill them.
To get around this, we perform a dry run to ensure that all required
code is loaded. It isn't particularly pretty (or fast) but it saves
us the hassle of maintaining a module list (cf. embedded mode).
|
|
This test is irrelevant as the new implementation doesn't use async
threads.
|
|
This introduces a way to retrieve erlang terms from NIF IO queues
without having to resort to copying.

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.

This function is no longer needed as maps:iterator has
now been implemented.
|
|
This iterator implementation fetches multiple elements to
iterate over in one call to erts_internal:maps_next instead
of one at a time. This means that the memory usage will go
up for the iterator as we are buffering elements, but the
usage is still bounded.
In this implementation the max memory usage is 1000 words.
Using this approach makes the iterator as fast as using
maps:to_list, so maps:iterator/2 has been removed.
|
|
The efile driver will soon be reimplemented as a BIF.
Instead of opening a port based on efile, use hd(erlang:ports()). It
is a reasonable safe assumption that the runtime will continue to use
use at least some ports.

to avoid tuple fallbacks for export funs and bitstrings.
ToDo: Re-encode if receiver turn out to be erl_interface/jinterface.

Removed distribution_SUITE:applied_monitor_node
as it seems to test apply of trapping BIF
and monitor_node does not trap anymore.
|
|
and remove ugly encoding fallback as {fun, ...}
DFLAGS_NEW_FUN_TAGS has been supported by vm/erl_interface/jinterface
since R13 or even older.
Renamed test case obsolete_funs to term2bin_tuple_fallbacks
and removed test for {fun,...} fallback
and added missing test for bitstring fallback {Binary, Bits}.
