Now that stdout can be set as non-blocking by the ttsl driver
we can no longer use putc and friends for the stdout/stderr
streams. Therefore we fallback on write.

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.

If the fd_driver is given non-tty fds it will now use an async thread
instead of doing a blocking write. An example of a non-tty fd is the
fd used by stderr, but could be anything handed down to the driver.
|
|
Instead of using blocking call to fwrite, the tty driver
now uses non-blocking calls to writev and queues any output
data that cannot be written into the driver queue. Without
this change an stdout write could block an entire scheduler
if for some reason the pseudo tty on the other side does not
consume the output of the Erlang shell.

This commit only changes the test. It reverts commit 710a1fa
([reltool] Adapt tests to better quoting of paths on windows) because
the commit that actually changed the quoting behaviour on windows was
moved from the maint branch to master (9633e0e win32: Fix quoting of

This ticket is about records in Erlang code, and when to check the
fields against the (optional) types given when defining records.
Dialyzer operates on the Erlang Core format, where there are no trace
of records. The fix implemented is a Real Hack:
Given the new option 'dialyzer' erl_expand_records marks the line
number of records in a way that is undone by v3_core, which in turn
inserts annotations that can be recognized by Dialyzer.

The purpose of add_abstract_code is to give Dialyzer some
abstract code so that it will not fail fatally when analysing
prim_eval which was compiled from BEAM assembly.
But if Dialyzer were to pass along the compiler options
that the module was compiled with when translating the
abstract code to Core Erlang, the 'from_asm' option would
crash the compilation. Thus, since we are already cheating,
we should cheat a little bit more and also remove the
'from_asm' option.
