2018-01-15 | erts: Fix float_to_list(F, [{decimals,D}]). | Sverker Eriksson | |
Example symptom: 1> float_to_list(0.145, [{decimals,1}]). "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 | |||
2018-01-03 | Replace the libc environment with a thread-safe emulation | John Högberg | |
putenv(3) and friends aren't thread-safe regardless of how you slice it; a global lock around all environment operations (like before) keeps things safe as far as our own operations go, but we have absolutely no control over what libc or a library dragged in by a driver/NIF does -- they're free to call getenv(3) or putenv(3) without honoring our lock. This commit solves this by setting up an "emulated" environment which can't be touched without going through our interfaces. Third-party libraries can still shoot themselves in the foot but benign uses of os:putenv/2 will no longer risk crashing the emulator. | |||

2017-07-17 | erts: Remove ERTS_SMP and USE_THREAD defines | Lukas Larsson | |
This refactor was done using the unifdef tool like this: for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done where defile contained: #define ERTS_SMP 1 #define USE_THREADS 1 #define DDLL_SMP 1 #define ERTS_HAVE_SMP_EMU 1 #define SMP 1 #define ERL_BITS_REENTRANT 1 #define ERTS_USE_ASYNC_READY_Q 1 #define FDBLOCK 1 #undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT #define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0 #define ERTS_POLL_USE_WAKEUP_PIPE 1 #define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1 #undef ERTS_HAVE_PLAIN_EMU #undef ERTS_SIGNAL_STATE | |||
2017-07-06 | Allow toggling lock counting at runtime | John Högberg | |
The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and all categories are still enabled by default, but the actual counting can be toggled at will. OTP-13170 | |||
2017-05-04 | Update copyright year | Raimo Niskanen | |
2017-04-27 | Rename macro and add clarifying comment | Richard Carlsson | |
The macro previously named 'LOG2' is in fact computing the LSB (not the MSB) of its input, and can only be used to compute log2(n) when n is is a power of 2, that is, when its LSB is also its MSB. | |||

2017-03-22 | erts: Don't allocate memory during signal handling | Björn-Egil Dahlberg | |
Allocations and message sending are now scheduled by a signal, via a signal state bitmap, instead of doing it directly in the signal handler. | |||
2017-03-21 | erts: Make sigterm signal safe for non-smp beam | Björn-Egil Dahlberg | |
The signal handler will now schedule a sigterm message instead of sending the message in the signal handler. The signal handler must refrain from memory allocations and thus the event is scheduled. | |||
