2016-08-29Fix purge of codeRickard Green
Ensure that we cannot get any dangling pointers into code that has been purged. This is done by a two phase purge. At first phase all fun entries pointing into the code to purge are marked for purge. All processes trying to call these funs will be suspended and by this we avoid getting new direct references into the code. When all processes has been checked, these processes are resumed. The new purge strategy now also completely ignore the existence of indirect references to the code (funs). If such exist, they will cause bad fun exceptions to the caller, but will not prevent a soft purge or cause a kill of a process having such live references during a hard purge. This since it is impossible to give any guarantees that no processes in the system have such indirect references. Even when the system is completely clean from such references, new ones can appear via distribution and/or disk.

2016-05-16Tolerate bad directories in the code pathBjörn Gustavsson
A bad directory in the path would prevent the run-time system from starting: $ echo >foobar $ erl -pa foobar {"init terminating in do_boot",{load_failed,[supervisor,kernel,gen_server,file_io_server,filename,file,erl_parse,error_logger,code_server,erl_lint,proc_lib,code,application_controller,application_master,gen_event,application,error_handler,lists,heart,gen,file_server,ets,erl_eval]}} Crash dump is being written to: erl_crash.dump...done init terminating in do_boot () The reason is that when attempting to read each of the BEAM files, there would be an 'enotdir' error which erl_prim_load:get_modules/2,3 assumed was a fatal error. Update erl_prim_load:get_modules/2,3 to ignore any error and try the next directory in the path. Reported-by: http://bugs.erlang.org/browse/ERL-142 Reported-by: Michael Truog

* bjorn/fix-on_load/OTP-12593: Update documentation regarding improvements Correctly handle multiple load attempts when on_load is pending Avoid deadlock when an on_load function makes an external call to the module itself code_server: Eliminate unnecessary Tag in handle_call/3 Reimplement -on_load() Refactor erts_finish_loading() and insert_new_code() code_SUITE: Make on_load_binary/1 clearer by using merl
2016-05-04Correctly handle multiple load attempts when on_load is pendingBjörn Gustavsson
If an on_load function had not yet returned, the code server would only correctly handle calls to code:ensure_loaded/1. That is, each process that called code:ensured_loaded/1 for the module in question would be suspended until the on_load function had returned. The code server handled calls to code:load_binary/1, code:load_file/1, and code:load_abs/1 in the same way as for code:ensure_loaded/1. That means that if call to one those functions attempted to load *different* code for the module, that code would not get loaded. Note that code:finish_loading/1 (code:atomic_load/1) will still return {error,pending_on_load} if there is a pending on_load function for one of the modules that are about to be loaded. The reason is that code:finish_loading/1 is meant to either succeed directly, or fail quickly if there is any problem.
