2015-03-10kernel: Fix file:read_line/1 unicode error handlingDan Gudmundsson
When a file was opened with some unicode encoding, file:read_line/1 could return unicode codepoints > 255 in list mode and wrong error message in bin mode. Chose to break out 'get_line' functionality from get_chars/5 since 'get_until' handling is different (comes from io module which should return unicode lists) and seems to have its own (doc?) problems.

An erroneous lookup option is needed to trigger the bug, and that can only enter the system from a parsed file e.g .inetrc. Pinpointed by Emil Holmström

I was going through application_controller.erl looking for why something was behaving a certain way, saw a comment about removing this duplicated code one day, and decided to move that a step forward.

2014-10-16Fix io:columns/0 timeout when invoked via userJosé Valim
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. OTP-12241
2014-10-16kernel,ssh: Add synchronous user_drv protocolLukas Larsson
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. OTP-12240

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).
