Matching out an 8-bit integer is faster than matching out
an utf8-encoded code point, even if the value of the code
point is less than 128. The reason is that matching out
an 8-bit integer is specially optimized to avoid a function
call. Do a similar optimization for matching out an utf8
segment.

The call "erlang:get_stacktrace()" is not handled explicitly. If there
are issues, they can probably be ignored since erlang:get_stacktrace/1
will be deprecated and removed.

Before:

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.

Fix GC bug for HiPE primop bs_put_utf8
|
|
in order to detect incompatible changes in primop interface
(which we just did for bs_put_utf8) and refuse hipe loading.
|
|
by preventing it from doing GC, which generated code relies on.
|
|
This is *ONLY* relevant for drivers/NIFs, so it's probably counter-
productive to document it elsewhere.
|
|
Previously we accepted trailing NULs, which was backwards compatible
as such usage never resulted in misbehavior in the first place. The
downside is that it prevented erts_native_filename_need from
returning an accurate number of *actual characters*, needlessly
complicating encoding-agnostic code like erts_osenv.
|
|
The standard search order does not include the directory that the
loaded DLL resides in, requiring dirty $PATH hacks to get things
working, which is not an option now that os:putenv/2 is divorced
from the OS environment.
|
|
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.

Symptom: "Closing pipe in state Waiting. Event lost?"

Add syntax in try/catch to retrieve the stacktrace directly
|
|
|
|
When a dirty NIF is executed a "schedule in" trace event is
generated, which may in turn result in a generic system task being
created, causing the process to be scheduled out as it can't run
dirty with pending tasks.
This is usually fine since said system task is seldom created, but
ERTS_FORCE_ENIF_SEND_DELAY was de-facto always on for debug builds,
causing the process to bounce between dirty and normal schedulers
forever.
This commit is not a complete fix and it can go off the rails even
on normal builds; if there's a lot of dirty jobs lined up and the
receiver's msgq lock happens to be busy at the wrong time, the
additional trace messages generated through this will hammer the
lock and keep everything bouncing.
