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

2014-08-14Refactor erl_epmd:names/1Luca Favatella
Simplify erl_epmd:names/1, keeping the same functionalities, relying on inet:gethostbyname/1 being able to handle both atoms and strings.
2014-08-14Accept inet:ip_address() in net_adm:names/1Luca Favatella
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.

* maint: Allow unsticking pre-loaded modules
2014-06-12Allow unsticking pre-loaded modulesBjörn Gustavsson
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.

2014-06-04Make pre-loaded modules permanently stickyBjörn Gustavsson
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.
2014-05-26Teach code:del_path/1 to ignore superfluous slashesBjörn Gustavsson
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.

2014-04-11Store expanded config in application_controller:change_application_dataSiri Hansen
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.

2014-03-26ose: Implement tcp inet driver for OSELukas Larsson
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.
