Allow escripts with only two lines
OTP-14098
|
|
The current implementation assumes that escripts all have at least
three lines. But according to the escript documentation, comments
on the second line and emulator flags on the third line are all
optional. Thus escripts with only two lines -- shebang on the
first line and code on the second line -- will not run. This commit
fixes the problem by rearranging the escript header parsing logic,
and recognize the escript body on the second line if the header only
contains a line of shebang.

The types in erl_parse.yrl are more in harmony with the description in
The Abstract Format (in ERTS User's Guide).

Make sure that we always test the "+fnu" option on all
systems. It seems that it was not tested in our daily
builds, since they are run non-interactively.
Make sure that we sort the list of names in do_unicode/1.
Otherwise the test would only work in "+fnl" mode because
the list would only contain one element.

Do not start an event timer unless there are no enqueued events.
|
|
Handling of timers and timeouts has been cleaned up
and generalized.
Semantic change regarding state timeout zero:
Previously if one state caused a state timeout zero and
managed to stay in the same state to insert additional
timeout zero(s) in the next state callback invocation, then
there would be only one timeout zero event. The mindset
was that the machine was faster then the timeout zero.
This has changed with the mindset that all state callback
invocations should be independent, so now the machine will
get one state timeout zero event per started state timeout
zero.
Note that just using zero timeouts is fairly esoteric...

Running 'dbg:fun2ms(fun([]) -> return_trace() end' resulted in an error
"dbg:fun2ms requires fun with single variable or list parameter"
But the empty list is actually a list and it is a valid value as a
match-spec head (matching on arity-0 functions).
Although its practical use is questionable this commit eliminates a
small limitation of ms_transform which is not present in the match-spec
grammar.

OTP-13633
|
|
When a simple_one_for_one supervisor is shutting down, and a child
exits with an exit reason of the form {shutdown, Term}, handle it as
if the exit reason were 'shutdown', without printing an error report.
This makes the behaviour of wait_dynamic_children match that of
do_restart.
This fixes ERL-163.
