This test consistently failed on Windows when an interface was
enabled but unplugged, as the interface was 'up' but not 'running'.
|
|
The small sub-binary conversion trick in the GC broke this test
pretty often on some machines.

binary:bin_to_list had a poor implementation that resulted in
excessive garbage collection. binary_to_list is almost identical and
has a generally better implementation, so I've replaced
binary:bin_to_list's CIF with a thin wrapper around binary_to_list.
Granted, binary_to_list has a deprecated indexing scheme, but we're
unlikely to ever remote it entirely and it's somewhat easy to move
it to the 'binary' module later on.
|
|
It is not simple to do the correct de-allocation on
a dirty schedulers, so we just delay it until this
process runs on a normal scheduler.
|
|
Update advanced.xml with correct default for number of processes

dialyzer: Compute MD5s using the .beam file (OTP-14937)
|

To the best of our knowledge this was introduced since file operations
on device files/FIFO:s could hang the emulator forever back when the
emulator was single-threaded and lacked IO threads; a read operation
could block all progress preventing the write operation it waited for
from occurring.
Granted, this could still happen through starving all dirty IO
schedulers, but the same issue can arise with NFS files which we've
always allowed.
Removing this restriction also lets us remove a stat(2) call that was
added to specifically allow `/dev/null`.

* john/erts/nif-binary-iovec-fixes/OTP-14845/OTP-14931/OTP-14932:
Suggest using enif_make_new_binary when possible
Make enif_make_binary return heap binaries if possible
Expand ErlNifBinary by another word for future additions
Unconditionally transfer ownership to the created term
Tweak asserts and explain why the copy buf doesn't use the tmp obj list
Free temporary iovecs through the tmp object list
Add a helper function for attaching tmp objects to NIF environments
|
|
While enif_make_binary will create heap-binaries from ErlNifBinaries
when possible now, enif_alloc_binary still allocates a Binary* off-heap
which is avoided entirely with enif_make_new_binary.
|
|
This does not avoid allocating a ProcBin since we still need to
release the binary somehow (and using the tmp obj list is slightly
slower since it's an unavoidable off-heap allocation), but it does give
us a hard limit on how long said ProcBin will live, which is a lot
better than before.

When fixing OTP-14931/14932 we had to settle for a solution that
decreased performance in a few corner cases like multiple calls to
enif_make_binary, as the other options on the table required extra
fields which would have broken ABI compatibility.
This is ABI-compatible since the fields are unused and at the end.
|
|
This fixes two corner-cases:
1) We will no longer return an invalid term when a binary inspected
on environment A is used in enif_make_binary on environment B
2) A double-free in this sequence of events:
* enif_alloc_binary(size, &bin);
* enif_ioq_enq_binary(ioq, &bin, skip);
* enif_make_binary(env, &bin);
* enif_make_binary(env, &bin);

Attaching to a ProcBin is the fastest way to delay the release of an
already allocated Binary, but alloc_tmp_obj is a lot faster when
starting from scratch since it usually uses temp_alloc.

The EX1-MIB cannot be compiled because of the missing IMPORT of "experimental".
The other instances EX1-MIB.mib (otp/lib/snmp/examples/ex1, lib/snmp/test/snmp_test_data)
are correct. I synchronized the documentation with them.
