To get a consistent naming scheme where
FBLK = Free block
ABLK = Allocated block
|
|
|
|
by making use of the new block header scheme to find the carrier header
and thereby the allocator.
|
|
Make use of type FreeBlkFtr_t
Rename GET_MB_CARRIER into BLK2MBC (like BLK2SBC)
Remove some unused macros
|
|
to allow realloc to determine block size (in MBC or SBC)
without having to read the footer of the previous block
that might be written to by concurrent thread.

Not setting ERL_CRASH_DUMP_SECONDS will now terminate beam
immediately on a crash without writing a crash dump file.
Setting ERL_CRASH_DUMP_SECONDS to 0 will also terminate beam
immediately on a crash without writing a crash dump file, i.e. same as not
setting ERL_CRASH_DUMP_SECONDS environment variable.
Setting ERL_CRASH_DUMP_SECONDS to a negative value will let the beam wait
indefinitely on the crash dump file being written.
Setting ERL_CRASH_DUMP_SECONDS to a positive value will let the beam wait
that many seconds on the crash dump file being written.
A positive value will set both an alarm in beam AND a heart timeout for restart
if heart is running.
This is due to the change of 'heart' behavior when 'heart' is
listening for a crash.

|
|
When a crash dump is about to be written and we have
heartbeat enabled on a system. We need time to write it
before heart explicitly kills the beam.

Perl 5.16.1 (and perhaps other versions) issues the following
warning:
defined(@array) is deprecated at utils/beam_makeops line 1714.
(Maybe you should just omit the defined()?)
for the following line:
$prev_last = pop(@{$gen_transform{$key}})
if defined @{$gen_transform{$key}}; # LINE 1714
The documentation for "defined" says that its use on hashes and
arrays is deprecated and that it may stop working in a future
release.
Simply removing "defined" (as suggested by the warning message)
will not work, as there will be an error when trying to use an
undefined value as an array reference:
Can't use an undefined value as an ARRAY reference at
utils/beam_makeops line 1714.
What we must do is to check whether $gen_transform{$key} is
defined before trying to use it as an array reference.

Peeloff feature of SCTP association creates a new socket which is not
set to nonblocking.
Function for receving data is shared with udp which has a default
loop when reading packets which is set to 5.
Calling the receive function more then once, is fine as long as
there are more data to receive or socket are nonblocking.
Set new peeled off socket to be nonblocking to prevent a erlang vm hangup.

In the erl_crash.dump file, native-compiled modules did not have
any information about attributes and compilation.
The problem is that the code:make_stub_module/3 BIF (which is
internally used when native code is loaded) did not copy the size
field the attribute and compilation info chunks. Those size fields
are only used when writing crash dumps.

Make sure io is flushed when driver is closed
|
|
|
|
|
|
Sometime when executing an tty io operation just before
the emulator terminated, the io message would get lost.
This commit makes sure that there is no io in the fd driver
before shutting down.
|
|
The concept of code_write_permission is used by tracing as well
and is not specific to code_ix.
