2010-07-07Fix format_status bug for unregistered gen_event processesGeoff Cant
Port the gen_fsm code for format_status to gen_event in order to prevent a lists:concat([...,pid()]) crash when calling sys:get_status/1 on an unregistered gen_event process. Refactor format_status header code from gen_* behaviours to module gen. Extend the format_status tests in gen_event_SUITE to cover format_status bugs with anonymous gen_event processes.
2010-05-27handle {global, term()} names in format_status/2Steve Vinoski
The gen_fsm, gen_server, and wx_object format_status implementations fail to handle global names of the form {global, term()} where term() is something other than an atom, pid, or list. Change these format_status implementations to treat names that are atoms, pids, or lists as before, but for all other terms, set the header property of the function return value to a tuple whose first element is a string describing the return value and whose second element is the name term. Add unit tests for gen_server and gen_fsm to verify sys:get_status calls work successfully for globally registered instances.
2010-05-12Extend format_status for gen_server/gen_fsm termination error loggingSteve Vinoski
When a gen_server or gen_fsm process terminates abnormally, sometimes the text representation of the process state can occupy many lines of the error log, depending on the definition of the state term. Developers sometimes would like a way to trim out parts of the state from the log if those parts don't contribute to documenting the circumstances of the error, thereby helping to reduce the amount of logged output. Since the format_status callback can already format and specialize gen_server and gen_fsm state for inclusion in the term returned from sys:get_status, this patch extends format_status in a backward-compatible way to also be able to specialize the state logged for abnormal gen_server and gen_fsm termination, and includes new unit tests to verify the new functionality. This patch also eliminates the previous restriction that the status returned by format_status must be a list. It can now be any term. The documentation is extended to cover the new usage for format_status, and it's been improved to recommend a form for the normal case that allows the returned status to fit well with the rest of the term returned by sys:get_status. The documentation is clear that this form is only recommended, not required.
