| | | * erts: Fix alloc_SUITE:migrationSverker Eriksson2017-12-201-1/+4
| | | | | | | | | | | | | | | | | | | | It crashed due to recursive calls to alloc_util in carrier initialization test callback.
| | | * erts: Improve carrier pool searchSverker Eriksson2017-12-205-424/+539
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Give back carrier to owner when put in pool with use of dd-queue. * Replace pooled_list with pooled_tree for more efficient search of all owned pooled carriers. * Remove traitor_list as it does not serve much purpose anymore. * Add HOMECOMING bit flag in crr->allctr atomic to (1) avoid double enqueue into dd-enqueue. (2) trigger read barrier in get_used_allctr for newly received carriers.
| | | * erts: Improve alloc_SUITE:migrationSverker Eriksson2017-12-204-49/+132
| | | | | | | | | | | | | | | | to mix it up with some realloc calls.
| | | * erts: Refactor carrier dealloc migrationSverker Eriksson2017-12-202-66/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | by adding a dedicated 'homecoming_dd_block' to use in dd-queue. + Preparation for dd-queue-migration of non-empty carriers. + Get rid of ugly hack where blk->carrier pointer is overwritten by dd-queue and then have to be restored.
| | * | erts: Add system_flags(erts_alloc,"+M?sbct *")Sverker Eriksson2018-02-1210-35/+242
| | | | | | | | | | | | | | | | | | | | | | | | to change sbct limit in runtime for chosen allocator type. With great power comes great responsibility.

| | * | erts: Refactor erl_ao_firstfit_allocSverker Eriksson2018-02-083-66/+77
| | | | | | | | | | | | | | | | | | | | | | | | In preparation for carrier age order. Change 'flavor' to 'blk_order' and 'crr_order'.

* | | Fix size of fmt_double()'s format_str[] bufferMikael Pettersson2018-02-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | fmt_double() may write up to 8 characters into its format_str[] buffer, which however only has room for 7 characters. This case could be triggered by a call to erts_printf_format() with any floating-point format that also includes #, and + or a space, which may be uncommon, but a nif or driver could issue it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | particularly slow erlc when compiler is hipe compiled. hipe_unified_loader:load did not patch external call sites and instead caused a double hipe mode switch per call. hipe_unified_loader:load is only used for early modules first loaded as beam and by code:atomic_load and friends.

"0.2" There were two problems in sys_double_to_chars_fast 1. Most serious was adding 0.55555555 / (10^D) instead of 0.5 / (10^D) which imposed a 5.5% risk of a faulty rounding up. 2. Using fixpoint for frac_part which lost significant bits if F < 0.5

For example, when converting in base 16, you could pass ':', ';', '<', '=', '>', and '?' without getting an exception. This was due to a missing check in c2int_is_invalid_char(). This change adds the missing check and a regression test for passing ':'. It also simplifies the code and tightens up an out-of-bounds check to make it off-by-one rather than off-by-two.
