* siri/remove-overload/OTP-13184:
Remove module 'overload' from SASL
|
|
|
|
Change scheduler responsiveness to 'check_schedulers'.
|
|
Add functions to 'code' to allow loading of multiple modules
at once.
code:atomic_load(Modules) will load all modules at once, or fail
having loaded none of them. Since we cannot guarantee the atomicity if
there are modules with -on_load functions, the list of modules must
not contain any modules with an -on_load function.
Also, to make it possible to put an application into an inactive state
for as short time as possible, also add code:prepare_loading/1 and
code:finish_loading/1. They are used like this:
{ok,Prepared} = code:prepare_loading(Modules)
.
.
.
ok = code:finish_loading(Prepared)
code:ensure_modules_loaded/1 is useful as a pure optimization to
ensure that modules that will be needed soon have indeed been
loaded. It will not reload modules that have already been loaded and
it *will* accept modules that have an on_load function. Therefore, it
does not make sense to give any atomicity guarantees.
I did consider overloading the existing code:ensure_loaded/1
function, but rejected it because the return value is very
different. Having different forms of return values depending
on the types of arguments is confusing.

After loading a module without native code, it is still necessary
to call hipe_unified_loader:post_beam_load() to ensure that any
native calls to the module is done to the newly loaded module
(and not to a previous version of the module in native code).
Unfortunately, hipe_unified_loader:post_beam_load() can be slow
and most of the time it doesn't do anything because no previous
native code was loaded. Therefore, ad2962278f added a kludge using
the process dictionary to avoid calling post_beam_load() if no
native code at all has been loaded.
Remove the kludge by keeping track exactly of which modules that
have native code in the existing ets table. Also generalize
post_beam_load() to handle severals modules at once, since we
will soon need that functionality.

The main ets table kept by code_server contains several pieces
of information. Therefore, code_server:all_loaded/1 need to
filter the information in the table.
code_server:all_loaded/1 can be simplified if we use
ets:select/2. Currently, the filtering is done by filtering
away unwanted stuff ({sticky_dir,Mod} tuples). It is more
robust to filter on the stuff that we want to keep
({Mod,Path} tuples, where Mod is an atom) in case that we'll
add more auxiliary records to the table later.

When we are going to implement functions that can load many modules
at once, we don't the erl_prim_loader server to become a bottleneck.
Therefore, we need erl_prim_loader:get_modules/3 that can read many
BEAM files in parallel.
Note that we will not bother making reading from archive files
or using the inet loader efficient. That can be done later if it
turns out to be important.

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.

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.
