Add clarification on nil type
OTP-15222
|
|
As explained by @psyeugenic on Slack:
> empty list `[]` is regarded as a separate type from `list()`, `[]` < `list()`
> i.e. nil is `[]`

beam_validator: Fix false diagnostic for a receive nested in a try
OTP-15218
|
|
When an expression is only used for its side effects, we try to
remove everything that doesn't tie into a side-effect, but we
went a bit too far when we applied the optimization to funs
defined in such a context. Consider the following:
do letrec 'f'/0 = fun () -> ... whatever ...
in call 'side':'effect'(apply 'f'/0())
'ok'
When f/0 is optimized under the assumption that its return value
is unused, side:effect/1 will be fed the result of the last
side-effecting expression in f/0 instead of its actual result.

Transport accepted sockets that are in the error state, was not closed
properly.

My compiler benchmarks on modules with huge functions, show the
next_free_variable_name call to be expensive. It turns out one
of the 3 calls to the function was completely ignored.

When nesting a receive in a try/catch, there could be a false
diagnostic that a fragile term is used.

Even when `ct:sleep/1` accepts `Millisecs` as floats, `ct:timetrap/1` does not.
If you try to use it in a test, you get the following error:
```erlang
{invalid_time_format,0.1}
```

* lukas/erts/seq_trace_fix_token_clear/ERL-602/OTP-15038:
erts: Fix seq_trace to not clear token for system messages
|
|
A lot of erts internal messages used behind APIs to create
non-blocking calls, e.g. port_command, would cause the seq_trace
token to be cleared from the caller when it should not.
This commit fixes that and adds asserts that makes sure
that all messages sent have to correct token set.
Fixes: ERL-602

Fix NIF stack recursion bug and enforce a limit
|
|
Fix recursion bug when decoding Constructed value within another
value - here the allowed buffer for the recursed decode shall
only be the size of the enclosing value, not the whole buffer.
Return ASN1_ERROR if BER decode recurses more than about 8 kWords.

Fix spec for erl_syntax_lib:analyze_type_application/1

There is no reason to have a larger buffer than this as
the recvmsg call will never return more data.

Before this change, if a write to the uds failed due to
EMFILE to ETOOMANYREFS the entire vm would crash. This
change makes it so that an SIGCHLD is simulated to that
the error is propagated to the user instead of terminating
the VM.
