The io_list_len() function returns an int, where a negative return
value indicates a type error. One problem is that an int only consists
of 32 bits in a 64-bit emulator. Changing the return type to Sint
will solve that problem, but in the 32-bit emulator, a large iolist
and a iolist with a type error will both return a negative number.
(Noticed by Jon Meredith.)
Another problem is that for iolists whose total size exceed the
word size, the result would be truncated, leading to a subsequent
buffer overflow and emulator crash.
Therefore, introduce the new erts_iolist_size() function which
returns a status indication and writes the result size through
a passed pointer. If the result size does not fit in a word,
return an overflow indication.

Use of Uint instead of UWord could cause overflow errors on systems
with large memory use.
|
|
|
|
Also add 'low' field in system_info(allocator)
SHORT_LIVED is still in low memory

This one is less likely to provoke error as one of the terms is
always NULL-based.
|
|
Also rename the fun_to_port/1 test case to outputv_errors/1 and
test sending more kinds of bad data to an outputv-enabled driver.

io_list_vec_len() is slightly more general than it needs to be.
Specifically:
* The only caller always passes ERL_SMALL_IO_BIN_LIMIT as the
value for the bin_limit parameter, so the bin_limit parameter
can be eliminated.
* The only caller never passes any NULL pointers, so there is
no need test the pointers before writing through them.

iolist_size/1 would silently return a truncated result for iolists
whose size exceeded the word size. For example:
iolist(lists:duplicate(256, <<0:(1 bsl 24)/unit:8>>)).
would return 0 (instead of 4294967296 or 1 bsl 32).
Rewrite iolist_size/1 to accumulate the size in a bignum if
necessary and result the correct result.

Fix thread unsafe access to process status field introduced in OTP-9125.
|
|
|
|
The status of a process was unnecessarily set to waiting before
the process was enqueued in a run queue. This bug was harmless
up until OTP-R14B01. In OTP-R14B02 erlang:hibernate/3 was fixed
(OTP-9125). After the introduction of OTP-9125, the previously
harmless process status bug sometimes caused erroneous badarg
exceptions from process_info().

Fix an error message by using an unsigned integer specifier as seen in
a tweet by @metabrew:
#erlang VM crashed with "no next heap size found: -2090496108,
offset 0", suddenly allocated all available RAM
Also correct mis-typed string formats in bif.c.

Calling a BIF thaf is called as a function (such as process_info/{1,2})
would leave a non-zero value in c_p->cp, which would lead to
duplicate entries in the stacktrace.
|
|
For some historical reason, the transformation of a func_info/3
instruction to the internal i_func_info/4 instruction is more
involved than it needs to be. Remove the gen_func_info() function
in the loader and use a simple transformation.

Add the enif_is_exception function to allow callers to determine
whether an ERL_NIF_TERM represents an exception. (Currently the only
supported exception is badarg since only enif_make_badarg exists, but
this will likely be expanded in future releases.) This allows NIF code
to call other NIF functions that return ERL_NIF_TERM and properly
check to see if the returned terms are exceptions. Without the
enif_is_exception function, developers have to create their own means
of checking whether a function creates an exception, such as returning
boolean success/failure indicators or some other special value
indicating that an exception is in effect.
The declaration of enif_is_exception in erl_nif_api_funcs.h respects
the order of declarations required to keep compatibility on Windows.
Add a new test to verify the operation of enif_is_exception.
Modify the erl_nif man page to add a description of enif_is_exception
and also to clarify the requirements of calling the enif_make_badarg
function. If code calls enif_make_badarg, the env passed in gets set
with exception information and so the return value of the calling
function MUST be the badarg term returned from enif_make_badarg. Also
clarify that the result of enif_make_badarg may be passed only to
enif_is_exception and not to any other NIF API functions.
