+ Leave control back to gen_server during supervisor's + restart loop

+

+ When an attempt to restart a child failed, supervisor + would earlier keep the execution flow and try to restart + the child over and over again until it either succeeded + or the restart frequency limit was reached. If none of + these happened, supervisor would hang forever in this + loop.

+

+ This commit adds a timer of 0 ms where the control is + left back to the gen_server which implements the + supervisor. This way any incoming request to the + supervisor will be handled - which could help breaking + the infinite loop - e.g. shutdown request for the + supervisor or for the problematic child.

+

+ This introduces some incompatibilities in stdlib due to + new return values from supervisor: + restart_child/2 can now return + {error,restarting} delete_child/2 can now + return {error,restarting} which_children/1 + returns a list of {Id,Child,Type,Mods}, where Child, in + addition to the old pid() or 'undefined', now also can be + 'restarting'.

+

+ *** POTENTIAL INCOMPATIBILITY ***

+ If a temporary child's start function returned 'ignore', + then the supervisor would keep it's child specification. + This has been corrected. Child specifications for + non-existing temporary children shall never be kept.

Use universal time as base in error logger +

+ Previous conversion used the deprecated + calendar:local_time_to_universal_time/1

Calling a guard test (such as is_list/1) from the + top-level in a guard, would cause a compiler crash if + there was a local definition with the same name. + Corrected to reject the program with an error + message.

The function digraph_utils:condensation/1 used + to create a digraph containing loops contradicting the + documentation which states that the created digraph is + free of cycles. This bug has been fixed. (Thanks to + Kostis Sagonas for finding the bug.)

When an escript ends now all printout to standard + output and standard error gets out on the terminal. This + bug has been corrected by changing the behaviour of + erlang:halt/0,1, which should fix the same problem for + other escript-like applications, i.e that data stored in + the output port driver buffers got lost when printing on + a TTY and exiting through erlang:halt/0,1.

+

The BIF:s erlang:halt/0,1 has gotten improved + semantics and there is a new BIF erlang:halt/2 to + accomplish something like the old semantics. See the + documentation.

+

Now erlang:halt/0 and erlang:halt/1 with an integer + argument will close all ports and allow all pending async + threads operations to finish before exiting the emulator. + Previously erlang:halt/0 and erlang:halt(0) would just + wait for pending async threads operations but not close + ports. And erlang:halt/1 with a non-zero integer argument + would not even wait for pending async threads operations. +

+

To roughly the old behaviour, to not wait for ports + and async threads operations when you exit the emulator, + you use erlang:halt/2 with an integer first argument and + an option list containing {flush,false} as the second + argument. Note that now is flushing not dependant of the + exit code, and you can not only flush async threads + operations which we deemed as a strange behaviour anyway. +

+

Also, erlang:halt/1,2 has gotten a new feature: If the + first argument is the atom 'abort' the emulator is + aborted producing a core dump, if the operating system so + allows.

+ Add escript win32 alternative invocation. escript can now + be started as both "escript.exe" and "escript" (Thanks to + Pierre Rouleau)
