* josevalim/large-binary-strings/PR-1131/OTP-13794:
Move expansion of strings in binaries to v3_core
|
|
|
|
This speeds up the compilation of binary literals
with string values in them. For example, compiling
a file with a ~340kB binary would yield the following
times by the compiler:
Compiling "foo"
parse_module : 0.130 s 5327.6 kB
transform_module : 0.000 s 5327.6 kB
lint_module : 0.011 s 5327.8 kB
expand_module : 0.508 s 71881.2 kB
v3_core : 0.463 s 11.5 kB
Notice the increase in memory and processing time
in expand_module and v3_core. This happened because
expand_module would expand the string in binaries
into chars. For example, the binary <<"foo">>, which
is represented as
{bin, 1, [
{bin_element, 1, {string, 1, "foo"}, default, default}
]}
would be converted to
{bin, 1, [
{bin_element, 1, {char, 1, $f}, default, default},
{bin_element, 1, {char, 1, $o}, default, default},
{bin_element, 1, {char, 1, $o}, default, default}
]}
However, v3_core would then traverse all of those
characters and convert it into an actual binary, as it
is a literal value.
This patch addresses this issue by moving the expansion
of string into chars to v3_core and only if a literal
value cannot not be built. This reduces the compilation
time of the file mentioned above to the values below:
Compiling "bar"
parse_module : 0.134 s 5327.6 kB
transform_module : 0.000 s 5327.6 kB
lint_module : 0.005 s 5327.8 kB
expand_module : 0.000 s 5328.7 kB
v3_core : 0.013 s 11.2 kB

Remove the gs application

The gs application ws deprecated in R15B01.
|

Guard tests (e.g. is_list/1) are listed both in guard_bif/2 and
in new_type_test/2. That is a trap for anyone who wants to add
a new guard test. Let guard_bif/2 call new_type_test/2 so that
new guard tests only have to be added in one place.
While we are it, also sort the clauses in guard_bif/2 and
new_type/2.

It is possible that '...' is added later (OTP 20.0), but for now we
are not sure of all details.

* josevalim/supervisor-get-callback-module/PR-1000/OTP-13619:
Return callback module in supervisor format_status
|
|
|
|
The previous implementation of supervisor:get_callback_module/1
used sys:get_status/1 to get the supervisor inner state and
retrieve the callback module. Such implementation forbids any
other supervisor implementation that has an internal state
different than the #state{} record in supervisor.erl.
This patch allows supervisors to return the callback module
as part of the sys:get_status/1 data, no longer coupling the
callback module implementation with the inner #state{} record.
Notice we have kept the clause matching the previous
sys:get_status/1 reply for backwards compatibility purposes.

Seems to be the growing meta tables that is causing increasing
failed memchecks after load factor was lowered.
