This is mostly a pure refactoring.
Except for the buggy cases when calling erlang:halt() with a positive
integer in the range -(INT_MIN+2) to -INT_MIN that got confused with
ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT.
Outcome OLD erl_exit(n, ) NEW erts_exit(n, )
------- ------------------- -------------------------------------------
exit(Status) n = -Status <= 0 n = Status >= 0
crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0
The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and
ERTS_DUMP_EXIT are the same as before (even though their values have
changed).

Avoid yield in the BIF when input is small. This either yielding
before beginning to work in the BIF, or by allowing some more
reductions before yielding.

except the reference counter 'refc', as different callers
have different strategies regarding the lifetime of the binary.

- erlang:list_to_binary/1
- erlang:iolist_to_binary/1
- erlang:list_to_bitstring/1
- binary:list_to_bin/1
|
|
- erlang:binary_to_list/1
- erlang:binary_to_list/3
- erlang:bitstring_to_list/1
|
|
A common case is to wrap an argument to list_to_binary in a list
to ensure conversion can happen even though the argument may already
be a binary. Use fast path for this case.

Added: binary_to_integer/1,2, integer_to_binary/1,2

Can still not setup -a, but cerl works.

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.

The new_binary() function takes a size argument that is an
int. In the 64-bit emulator (sizeof(int) == 4, sizeof(Uint) == 8),
any sizes >= 0x8000000 become 0xffffffff80000000 and above and
triggers a memory allocation failure.
Change the type of the size argument to Uint, and change any
callers that cast the argument to an int.

This will reduce the risk of integer wrapping in bin vheap counting.
The vheap size series will now use the golden ratio instead of doubling
and fibonacci sequences.
OTP #8730
|
|
Merging the three off-heap lists (binaries, funs and externals) into
one list. This reduces memory consumption by two words (pointers) per
ETS object.
|
|
Add testcases for binary:list_to_bin/1 and binary:copy/1,2.
Add reference implementation of list_to_bin/1.
|
|
Add allcoator parameter to erts_get_aligned_binary_bytes_extra.
Add testcases for the functions above.
Add reference implementation for the functions above.
|
|
|
|
Set loop factors to 10.
Teach erts_debug:set_internal_state to limit loop factor for binary.
Add random tests for matches and match with multiple searchstrings.
|
|
Fix heap-hole when trapping in binary.c
Fix boyer more segfaulting when searchstring is longer than haystack
|
|
Add Boyer More implementation of binary:matches.
Cleanup and removed unused code.
|
|
Add testcase embryos and reference implementation.
Change name of compile function according to EEP31.
|
|
|
|
Fix safe_mul in the loader, which caused failures in the bit
syntax test cases.
Fix yet another Uint in erl_alloc.h (ERTS_CACHE_LINE_SIZE) causing
segmentation fault when we have many schedulers (why only in that
situation?).
Clean up erl_mseg (remove old code for the Linux 32-bit mmap flag).
While at it, also remove compilation warnings.
