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'.

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.
Thanks to Kostis Sagonas for finding the bug.

erl_lint: Disallow call to is_record/3 if there is a local is_record/3
Fix crash in trace_info({M,F,A}, Flags) when M:F/A has native code
Ensure that generated record operations don't call local functions
|
|
Attempting to call is_record/3 (without an erlang: prefix) from a
guard if there was a local function named is_record/3 would cause
a compiler crash. For consistency with other guard tests, disallow
the call.
is_record/2 in a guard will still be allowed (and work correctly)
even if there is a local is_record/2. It could be argued that
is_record/2 should be handled in the same way as is_record/3,
but changing that now could break working code.
|
|
Consistently use external (remote) calls to the BIFs element/2,
setelement/3, and is_record/3.

erl_lint: Consistently reject local calls from guards
|
|
* bjorn/compiler/bif-call-bug/OTP-9866:
erl_lint: Consistently reject local calls from guards
|
|
|
|
If a guard test (such as is_list/1) has a local definition in a
module (or is imported), erl_lint will reject a call to it from
a guard if the call is not at the top-level:
foo(L) when is_list(L) =:= true -> %% Will be rejected.
ok.
is_list(_) -> ok.
But if the call is at the top-level, it will be accepted (and
cause a crash in a later compiler pass):
foo(L) when is_list(L) -> %% Will be accepted by erl_lint
ok.
is_list(_) -> ok.
This inconsistency was an oversight introduced when it became
possible to override BIFs with local definitions.

Supervisor should never keep child specs for dead temporary children.

* siri/stdlib/dialyzer-log_mf_h/OTP-9754:
Fix dialyzer warning about gen_event callback init/1 in log_mf_h
|
|
The warning is about log_mf_h having a different spec for gen_event
callback init/1 than defined in gen_event.erl. log_mf_h allows return
value {error,Reason}, while gen_even only specifies successful return
values.
This commit add {error,Reason} as a valid return value to the
gen_event callback, since this is handled by the code.
|
|
Dialyzer complained over a mismatch between the callback spec of
Mod:code_change in gen_server and the spec of supervisor:code_change
(which is the implementation of a gen_server Mod:code_change).
This commit changes the callback spec to allow {error,Reason} as
return value. Also, release_handler is updated to handle this return
value.
