Binary matching can be confusing. For example:
1> <<-1>> = <<-1>>.
** exception error: no match of right hand side value <<"ÿ">>
2>
When constructing binaries, the value will be masked to fit in
the binary segment. But no such masking happens when matching
binaries.
One solution that we considered was to do the same masking when
matching. We have rejected that solution for several reasons:
* Masking in construction is highly controversial and by some
people considered a bad design decision.
* While masking of unsigned numbers can be understood, masking of
signed numbers it not easy to understand.
* Then there is the question of backward compatibility. Adding
masking to matching would mean that clauses that did not match
earlier would start to match. That means that code that has
never been tested will be executed. Code that has not been
tested will usually not work.
Therefore, we have decided to warn for binary patterns that cannot
possibly match.
While we are it, we will also warn for the following example where
size for a binary segment is invalid:
bad_size(Bin) ->
BadSize = bad_size,
<<42:BadSize>> = Bin.
That example would crash the HiPE compiler because the BEAM compiler
would generate a bs_get_integer2 instruction with an invalid size
field. We can avoid that crash if sys_core_fold not only warns for bad
binary pattern, but also removes the clauses that will not match.

andor_SUITE:check/2 function can be replaced with pattern matching.

In addition, the heart API is extended with the following functions:
* heart:set_options/1
* heart:get_options/0
If heart:set_options([scheduler]) is set, heart will check
scheduler responsiveness before every heartbeat to the heart port.

We will need them when we start to produce warnings for patterns
that can't match.
|
|
As a preparation for checking binary patterns we will add
var_list/2 that will work as pattern_list/2 but is guaranteed
not to throw an exception. That way, we will only have to use
try...catch for the few remaining calls to pattern_list/2.

Save work the *extremely* common case that the guard is

Prior to this commit, the debugger relied on a simple heuristic
that traverses directory from the beam file to find a source file.
The heuristic was maintained with this patch but, if it fails,
it fallbacks to the source value in the module compile info.
In order to illustrate how it works, one of the tests that
could not find its source now passes successfully (showing the
source lookup is more robust).

As recently discussed on the erlang-questions mailing list, this
example fails to start the ssl application because ssl depends on asn1
nowadays. Let's future-proof this by using
application:ensure_all_started/1.
