2018-04-20erts: Refactor erl_db_hash next() into next_live()Sverker Eriksson
where argument 'list' is the first candidate (not list->next). Also simplified db_first_hash().

Make stacktraces consistent when backtrace_depth is 0

2018-04-19Make stacktraces consistent when backtrace_depth is 0Björn Gustavsson
It is allowed to set the backtrace depth to 0, but when an exception is catched the stacktrace will still contain one element: 1> erlang:system_flag(backtrace_depth, 0). 8 2> catch error(badarg). {'EXIT',{badarg,[{shell,apply_fun,3, [{file,"shell.erl"},{line,908}]}]}} However, when an exception is raised using `erlang:raise/3`, there will be no elements in the stacktrace: 3> catch erlang:raise(error, badarg, [{fake,name,[arg],[]}]). {'EXIT',{badarg,[]}} Since the `error_handler` module uses `erlang:raise/3` to raise an exception when an undefined function is called, there will not be any stacktrace when calling an undefined function: 4> catch undef_module:undef_name(some_argument). {'EXIT',{undef,[]}} Fix this inconsistency by changing `erlang:raise/3` so that it always includes one element in the stacktrace: 3> catch erlang:raise(error, badarg, [{fake,name,[arg],[]}]). {'EXIT',{badarg,[{fake,name,[arg],[]}]}} 4> catch undef_module:undef_name(some_argument). {'EXIT',{undef,[{undef_module,undef_name,[some_argument],[]}]}}

christhekeele/remove-trace-terms-from-table-types-in-match-docs Remove trace-specific terms from docs for table-oriented matchspecs
2018-04-19Remove trace-specific terms from docs for table-oriented matchspecsChris Keele
This removes the matchspec instructions `is_seq_trace` and `get_tcw/0` from the documentation for table-oriented matchspecs. This is likely correct as both are already documented under "Functions Allowed Only for Tracing", despite appearing in the list of possible options for table specs. The following observations further back this change up: ```erl erlang:match_spec_test([whatever], [{'_', [], [{is_seq_trace}]}], trace). %=> {ok,true,[],[]} erlang:match_spec_test({whatever}, [{'_', [], [{is_seq_trace}]}], table). %=> {error,[{error,"Special form 'is_seq_trace' used in wrong %dialect."}]} erlang:match_spec_test([whatever], [{'_', [], [{get_tcw}]}], trace). %=> {ok,true,[],[]} erlang:match_spec_test({whatever}, [{'_', [], [{get_tcw}]}], table). %=> {error,[{error,"Function get_tcw/0 cannot be called in this context."}]} ```

2018-04-10erl_docgen: Add hover links for ghlinkLukas Larsson
All functions, datatype and h3 headings have gotten a hover attribute that shows a link directly to the edit page on github for easy editing of documentation. The github link links to the maint branch. An early attempt was done to use the SHA of the current branch, but that did not work well as github can only take pull requests from branches.

If messages are not flushed they would cause problems when the system is booting. For instance module load requests would be issued before the prim loader has been launched.
