Can still not setup -a, but cerl works.
2011-11-07erts: Remove debug variable in list_to_binaryBjörn-Egil Dahlberg
2011-05-10Fix overflow in list_to_bitstring/1Björn Gustavsson

2011-05-10Replace io_list_len() with erts_iolist_size()Björn Gustavsson
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.

2011-03-09Fix 18 exabyte memory allocation failureBjörn Gustavsson
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. Correction-by: Jon Meredith

2010-08-12Increase vheap counter to Uint64Björn-Egil Dahlberg
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
2010-07-20One off-heap list, to eliminate two words per ETS object.Sverker Eriksson
Merging the three off-heap lists (binaries, funs and externals) into one list. This reduces memory consumption by two words (pointers) per ETS object.
2010-05-17Add binary:list_to_bin/1 and binary:copy/1,2Patrik Nyblom
Add testcases for binary:list_to_bin/1 and binary:copy/1,2. Add reference implementation of list_to_bin/1.
2010-05-17Add binary:longest_common_prefix/longest_common_suffixPatrik Nyblom
Add allcoator parameter to erts_get_aligned_binary_bytes_extra. Add testcases for the functions above. Add reference implementation for the functions above.
2010-05-17Move binary module bif's to erl_bif_binary.cPatrik Nyblom
2010-05-17Count reductions for process even when not trappingPatrik Nyblom
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.
2010-05-17Add random compare testcasePatrik Nyblom
Fix heap-hole when trapping in binary.c Fix boyer more segfaulting when searchstring is longer than haystack
2010-05-17Teach BIF's binary:match/matches interrupting/restartingPatrik Nyblom
Add Boyer More implementation of binary:matches. Cleanup and removed unused code.
2010-05-17Teach binary.c the semantics to take longest instead of shortest matchPatrik Nyblom
Add testcase embryos and reference implementation. Change name of compile function according to EEP31.
2010-05-17Initial commit of the binary EEPPatrik Nyblom
2010-03-10Fix further test-suite problemsPatrik Nyblom
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.
