heart:get_cmd/0 is documented to return an empty string if the command is
cleared. get_cmd/0 returns 2 extra bytes: 1 byte for the trailing null,
1 byte from the op (the op is an unsigned char and 2 bytes are allocated
for it in the returned buffer).

terminates" and improved test suite
The bug fix supplied by Filipe David Manana <[email protected]>
did not cover all possible ways that a process may be terminated
as for instance with supervisor:terminate_child. Also there
was a bug in the base case of the patch returning a list of a list instead
of only the list.
Added a timeout for the test cases, eliminated unnecessary sleeps,
improved code.

The temporary child specs are never removed from the supervisor's state, and
have they're MFA component set to {M, F, undefined} instead of the MFA passed
in the supervisor:start_child/2 call. Subsequent calls to supervisor:restart_child/2
may crash. Stack trace example:
{badarg,[{erlang,apply,[gen_server,start_link,undefined]},
{supervisor,do_start_child,2},{supervisor,handle_call,3},
{gen_server,handle_msg,5},
{proc_lib,init_p_do_apply,3}]}

Fixed a couple of compilation errors. Also backed out a tiny change
that had already been added by Tuncer Ayaz in his binary-part-typo
branch.

This change fixes a bunch of small (and a few less small) typos and
other errors in various modules that I've spotted throughout my travels.

In a file containing declarations and comments without any empty lines
between them, the recomment_forms() function would associate a
multi-line comment with the declaration above it rather than the one
following it. (Thanks to Richard Carlsson.)
This bug has been reported several times. It was corrected by Kostis
Sagonas, but the fix didn't make into the R14B02 release.

The compiler (sys_core_fold) tries to avoid constructing tuples
in case expressions. The following code:
c(A, B) ->
case {A,B} of
{ok,X} -> X;
{_,_} -> error
end.
will be rewritten so that no tuple is built. If a clause
requires a tuple to be built as in this code:
c(A, B) ->
case {A,B} of
{ok,X} -> X;
V -> V %The tuple will be built here
end.
the tuple will be built in the clause(s) in which it is needed.
If the value returned from the case is not used as in this code:
c(A, B) ->
case {A,B} of
V -> V %Warning: a term is constructed, but never used
end,
ok.
there will be an incorrect warning. Basically, what happens is
that the code is reduced to:
c(A, B) ->
{A,B}, %Warning: a term is constructed, but never used
ok.
and the optimizer sees that the {A,B} tuple can't possibly be used.
Eliminate the warning by adding a 'compiler_generated' annotation
to the tuple.

Since the log_mf_h index file might be read by other processes than
the error handler (e.g. by the rb tool), this file should be updated
atomically. This will avoid hitting the time gap between opening the
file in write mode (and thus emptying the file) and the actual update
with the new contents. To do this, a temporary file is written, and
the file:rename/1 used to replace the real index file.

In the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz = wrong.
the Sz variable is supposed to be bound in the function header and the
matching "Sz = wrong" should cause a badarg exception. But what
happens is that the Sz variables seems to be unbound and the matching
succeds and the m/1 function returns 'wrong'.
If the Sz variable is used directly (not matched), it will have
the expected value. Thus the following code:
m(<<Sz:8,_:Sz/binary>>) ->
Sz.
will correctly return the value of Sz that was matched out from
the binary.

Setting code path options is useful e.g. when analyzing programs that
use parse transforms.

The default value 'undefined' was added to records field types in such
a way that the result was not always a well-formed type. This bug has
been fixed.
---
erl_pp has since OTP-8150 formatted types so that 'undefined' was
removed from union types assigned to record fields. Since one cannot
distinguish between 'undefined' added by the parser or supplied by the
user, a side effect was that user supplied 'undefined's were also
removed.
Now the pretty printer shows 'undefined' even if added by the parser.
This is a minor issue.

This is the correction of the bug not allowing the values 'strip' or
'all' for the app_file option in reltool.
