* lukas/erts/non-blocking-shell:
Fix io:columns/0 timeout when invoked via user
kernel,ssh: Add synchronous user_drv protocol

This patch fixes an issue where io:columns/0 times out when invoked from
any application callback (or any supervisor/supervised module since the
group leader is inherited).
To reproduce the issue, one must simply call io:columns() from any
application callback. You will notice the process will block for 2 seconds
which then times out and returns {:error, :enotsup}.
Note this bug only happens inside the erlang shell (using -noshell or
escripts do not trigger the bug).
To fix the bug, it is important to understand how io requests flow from
application callback processes. Here are the steps followed:
1. Since io:columns/1 is timing out, the first step is to find out who is the
group leader for the application callback process. Using process_info/1, we
can see the parent process is the application_master and handles
io_requests by delegating them to the group_leader.
2. By inspecting the application_master process, we can find the group_leader
the message is sent is the registered process named user. The process is
running the group module which does handle io:columns/1 requests delegating
them to user_drv process.
3. The user_drv process does handle tty_geometry requests, except that a
clause above ends up short-circuiting all tty_geometry requests from the
user process.
This patch moves the user clause below the specific driver messages.

Added a put_chars_sync to the protocol that can be used to
talk to user_drv and made group use it. This is needed in order
to guarantee that bytes has been pushed to the tty port when
doing something like this:
io:format("halting\n"),erlang:halt(0).
Before this change the halting message could be lost in the message
queue of the user_drv process, this is no longer possible.
This commit also fixes ssh_cli as that plugs itself in as a user_drv
process.

Sometimes we install *.erl files. Some these files include a private
*.hrl files, so in order to make these *.erl files usable we have to
install these private includes as well.

Simplify erl_epmd:names/1, keeping the same functionalities, relying
on inet:gethostbyname/1 being able to handle both atoms and strings.
|
|
This change also simplifies the code avoiding a double (conditional)
call to inet:gethostbyname/1 (in net_adm:names/1 and then
erl_epmd:names/1).

This fixes a bug introduced in f11aabdc9fec593c31e6c4f3fa25c1707e9c35df where
filelib:eval_read_file_info/2 was made to use file:read_link_info/1 to never
follow symlinks. This fixed wildcard/1 but broke every other function using
eval_read_file_info/2.

Allow unsticking pre-loaded modules
|
|
Commit ed06dd12ea74018b902a2c4c7924313d23cedb75 made pre-loaded
modules (such as erlang) sticky, and also made it impossible to
unstick them to prevent them from ever be reloaded.
It turns out that there are tools that may want to instrument
the erlang module (such as concuerror), so making it
impossible to unstick modules is harsh. Therefore, revert the
part of the commit that prevented unsticking the pre-loaded
modules.
|
|
|

Modules in the kernel, stdlib, and compiler applications are by
default "sticky", meaning that the code server will refuse to
re-load them.
The pre-loaded modules (those that are part of the run-time system
itself, such as 'erlang') are, however, not sticky. They used to be
sticky a long time ago when the pre-loaded modules were part of
the kernel application. Now they are part of the erts application.
Since re-loading a pre-loaded module can be catastrophic (especially
re-loading the 'erlang' module), the pre-loaded modules must be
sticky. Furthermore, it should not be allowed to unstick them.
The sticky_dir/1 test case in code_SUITE is never actually run and
is broken. Rewrite it.

The following sequence will NOT leave the code path unchanged:
code:add_path("/some/app/"),
.
.
.
code:del_path("/some/app/")
The reason is that code:add_path/1 will normalize the path name
(removing the trailing slash), while code:del_path/1 does not
normalize the path before searching for it in the code path.

* siri/appups-18.0/OTP-11881:
Update kernel, stdlib and sasl appup files for Erlang/OTP-18
|
|
|
|
|
|
If the Config given to application_controller:change_application_data
included other config files, it was only expanded for already existing
(loaded) applications. If an upgrade added a new application which had
config data in an included config file, the new application did not
get correct config data.
This is now changed so config data will be expanded for all
applications.
|
|
Also use this type in the start/2 callback spec.

ose: Implement tcp inet driver for OSE

ose: erlang display goes to ramlog printf
ose: Initiate stdin/stdout/stderr

ose: Reset busy port when pdq empty
ose: Restore the owner of the signal
|
|
This change relies on the assumption that all arguments before the last --
to the parent beam should be left as they are.
|
|
The inet driver for OSE has to handle signals instead of selects
and thus the wrappers for ready_input/output are a little bit
different. However the majority of the inet code remains the same.

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.
All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.

file:set_cwd/1 accepts binaries as arguments, however the binaries
must be properly encoded as per file:native_name_encoding/0.
Also update the note under no_translation error to refer that passing

Add flags to enable and use the LLVM backend:
* to_llvm: use the LLVM pipeline for compilation (default optimization level
is O3),
* llvm_save_temps: save the intermediate files in current directory in order
to be able to debug or optimize the LLVM assembly,
* {to_llvm, O}: set the optimization level of LLVM opt and llc tools.
Add some debug support to the loader; no semantic change intented.

The loader of native code tries to avoid race condition by bringing
down the system to a single scheduler. Unfortunately, that will not
completely avoid race conditions beacuse other processes may still
run while the code is being loaded. Therefore, we must still make
sure that native code has been fully fixed up before it can be
executed.
Under unlucky circumstances, it was possible for the global name
register process to call a fun in native code before the native
code for the fun had been fully fixed up. The run-time system
would crash when running the not-fully-fixed-up code.
Here is a way to make the bug 100% reproducible. First add this
function to the 'global' module:
silly_looper(List) ->
lists:foreach(fun(E) -> put(any_atom, E) end, List),
silly_looper(List).
Then insert the following code at the beginning of the init/1
function in the 'global' module:
spawn_link(fun() -> silly_looper(lists:seq(1, 100)) end),
The run-time system will crash during start up when the native
code for the 'global' module is being loaded. What will happen
is that lists:foreach/2 (which runs in native code) will call
the native code for the fun in silly_looper/1 before the reference
to 'any_atom' has been changed from a 0 to the proper tagged
atom value. The put/2 BIF will exit when attempting to calculate
the hash value for the illegal value 0 (it is not properly tagged).
To eliminate this race condition, we must delay patching the
native code addresses for a fun into the fun entry until the native
code has been fully fixed up. We will use the new BIFs introduced
in the previous commit.
While we are at it, we will also make sure that we erase any
temporary variables in the process dictionary used by the
hipe_unified_loader module.
|
|
This commit is a preparation for eliminating a race condition
loading the native code for modules whose BEAM code has already
been loaded. Here we introduce two new BIFs so that looking up
a fun entry is separate from setting the native address in the
fun entry.

The types array(), dict(), digraph(), gb_set(), gb_tree(), queue(),
set(), and tid() have been deprecated. They will be removed in OTP 18.0.
Instead the types array:array(), dict:dict(), digraph:graph(),
gb_set:set(), gb_tree:tree(), queue:queue(), sets:set(), and ets:tid()
can be used. (Note: it has always been necessary to use ets:tid().)
It is allowed in OTP 17.0 to locally re-define the types array(), dict(),
and so on.
New types array:array/1, dict:dict/2, gb_sets:set/1, gb_trees:tree/2,
queue:queue/1, and sets:set/1 have been added.
