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.
2013-04-01Use erlang:demonitor's flush option on timeoutLoïc Hoguin
It is equivalent to the few lines removed, except more efficient.
2013-04-01Don't lookup the node unless required in gen:call/{3,4}Loïc Hoguin
Move some operations that aren't required for the happy path. The operations were small, so they shouldn't show a big difference in benchmarks except for systems with many active gen processes.
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.
2013-03-29Document erl_parse:abstract/2Hans Bolinder
A bug has been fixed: when given the option {encoding,utf8} a list of floating point numbers (in the correct interval) was mistakenly returned as a string.

The scanner did not crash when a floating point number was encountered in the input string.

2013-03-19Let escript recognize an encoding comment on the second lineHans Bolinder
The manual says that an Emacs directive can be placed on the second line. With this patch that directive is also recognized when selecting encoding of the script.
2013-03-18Fix a test case bugHans Bolinder

2013-03-18Adjust dets.erl to cope with an evil test caseHans Bolinder
The test case deletes a Dets process while it is repairing a file. Another client waiting for the Dets process to reply then kicks in and repairs the file. Apparently the temporary file was still open, resulting in an eacces error on Windows.

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.
