* nox/erl_eval-receive/OTP-11137: Updated primary bootstrap for erl_eval Added preloaded prim_eval Fix receive support in erl_eval with a BEAM module

2013-05-28Fix receive support in erl_eval with a BEAM moduleAnthony Ramine
Using the low-level BEAM instructions, we can loop over each message in the process queue and removes the first message that matches, without receiving them all to later send them back to itself. The function prim_eval:'receive'/2 is equivalent to the following pseudo-code: 'receive'(F, T) -> RESET MESSAGE QUEUE POINTER, LOOP: case PEEK CURRENT MESSAGE WITH TIMEOUT T of {ok,Msg} -> case F(Msg) of nomatch -> DECREMENT TIMEOUT T, ADVANCE MESSAGE QUEUE POINTER, GOTO LOOP; Result -> RESET MESSAGE QUEUE POINTER, Result end; timeout -> RESET MESSAGE QUEUE POINTER, timeout end. To not break Dialyzer and other tools, we use a stub Erlang module which abstract code is forcefully inserted into prim_inet.erl afterwards compilation.
2013-05-22Teach c:ls/1 to show non-directory filesBjörn Gustavsson
In an email to erlang-questions, Bengt Kleberg wrote: When I use c:ls/1 it reminds me so much of Unix "ls" that I expect c:ls("filename") to work. The resulting error surprises me every time (not the same day). While teaching c:ls/1 to show non-directory files, update the error handling to make use of the POSIX error codes from file:list_dir/1 and file:format_error/1 (which had not been invented when the c module was first implemented).

This function is used all over the place in OTP itself and people sometimes want that functionality, they may as well not reimplement it themselves.

* sv/stdlib/sys-get-state/OTP-11013: Removed ?line macro add sys:get_state/1,2 and sys:replace_state/2,3 update sys:get_status/2,3 documentation for gen_event
2013-04-02add sys:get_state/1,2 and sys:replace_state/2,3Steve Vinoski
At Erlang Factory 2013 there was discussion during one of the talks about the sys:get_status functions and how useful they were for debugging. Geoff Cant mentioned it would be very useful if the sys module also provided functions to use while debugging to get just the state of a process and also to be able to replace the state of a process, and many others in the audience appeared to agree. The sys:get_state/1,2 functions return the state of a gen_server, gen_fsm, or gen_event process. The return value varies depending on the process type: process state for a gen_server, state name and state data for a gen_fsm, and handler module, handler id, and handler state for each handler registered in a gen_event process. The sys:replace_state/2,3 functions allow the state of a gen_server, gen_fsm, or gen_event process to be replaced with a new state. These functions take a function argument that updates or replaces the process state; using a function to change the state eliminates the race condition of first reading the state via sys:get_state/1 or sys:get_state/2, using its return value to create a new state, and then replacing the old state with the new state, since during that time the process might have received other calls or messages that could have changed its state. * For a gen_server process, the state replacement function takes the process state as an argument and returns a new state. * For a gen_fsm process, the state replacement function gets a tuple of {StateName, StateData} and returns a similar tuple that specifies a new state name, new state data, or both. * For a gen_event process, the state replacement function is called for each registered event handler. It gets a tuple {Module, Id, HandlerState} and returns a similar tuple that specifies the same Module and Id values but may specify a different value for HandlerState. If the state replacement function crashes or results in an error, the original state of a gen_server or gen_fsm process is maintained; if such a crash occurs for a gen_event process, the original state of the event handler for which the state replacement function was called is maintained, but the states of other event handlers of the same gen_event process may still be updated if no errors or crashes occur while replacing their states. Add documentation for sys:get_state/1,2 and sys:replace_state/2,3. The documentation explicitly notes that the functions are intended for use during debugging. Add new tests for these functions to gen_server_SUITE, gen_fsm_SUITE, and gen_event_SUITE.
2013-03-29update sys:get_status/2,3 documentation for gen_eventSteve Vinoski
Modify the documentation for the sys:get_status/2,3 functions to reflect that they also work on gen_event processes, and add a cross reference for gen_event:format_status/2 to go along with the existing cross references for gen_server and gen_fsm.

2013-03-08Delete obsolete note about simple-one-for-one supervisorMagnus Henoch
Since commit 47759479146ca11ad81eca0bb3236b265e20601d, simple-one-for-one supervisors _do_ kill their children explicitly on shutdown. That commit also removed this note, but it seems like the merge commit 45b4d5309e0686cc5fa28506de76f75b598bbd95 incorrectly reinstated it.

The code related to the introduction of unicode_string() and unicode_char() has been removed. The types char() and string() have been extended to include Unicode characters. In fact char() was changed some time ago; this commit is about cleaning up the documentation and introduce better names for some functions.
