This document describes the changes made to the ERTS application.

Erts 8.3 + +
Fixed Bugs and Malfunctions + + +

Fixed a number of bugs that caused faulty stack-traces + to be generated. The faulty stack traces were generated + either when applying the following functions or tracing + the following functions:

+ erlang:error/1 + erlang:error/2 + erlang:exit/1 + erlang:throw/1 +

+ Own Id: OTP-14055

+ + +

+ Corrected documentation about memory footprint for maps.

+

+ Own Id: OTP-14118

+ + +

+ Fix process_info(Pid, current_stacktrace) to use + stack depth limit set by + system_flag(backtrace_depth). The old behavior was + a hard coded depth limit of 8.

+

+ Own Id: OTP-14119 Aux Id: PR-1263

+ + +

+ A process calling erlang:system_flag(multi_scheduling, + block) could end up hanging forever in the + call.

+

+ Own Id: OTP-14121

+ + +

Dirty scheduler bug fixes:

Fixed + call time tracing of process being scheduled on dirty + scheduler.

GC info from dirty + schedulers.

Multi scheduling block + with dirty schedulers could crash the runtime + system.

Process structures could be + removed prematurely.

GC on dirty + scheduler could crash the runtime system.

 +

Termination of a process executing on a dirty + scheduler could cause a runtime system crash.

 + +

+ Own Id: OTP-14122

+ + +

+ Fixed crash that occurred when writing timer data to a + crash dump.

+

+ Own Id: OTP-14133

+ + +

+ A literal area could be removed while still referred from + processes.

+

+ Own Id: OTP-14134

+ + +

+ Fixed a bug in the garbage collector that could crash the + runtime system.

+

+ Own Id: OTP-14135

+ + +

+ Fixed a bug in call-time trace for NIFs which caused + tracing to erroneously be started multiple times for one + call.

+

+ Own Id: OTP-14136

+ + +

+ Remove a debug printout and an unnecessary garbage + collection when handling exceptions in hipe compiled + code.

+

+ Own Id: OTP-14153

+ + +

+ Fix bug in tracing of garbage collection that could cause + VM crash. Bug exists since OTP 19.0.

+

+ Own Id: OTP-14154

+ + +

+ Fix bug in binary_to_term for binaries created by + term_to_binary with option compressed. The + bug can cause badarg exception for a valid binary + when Erlang VM is linked against a zlib library of + version 1.2.9 or newer. Bug exists since OTP 17.0.

+

+ Own Id: OTP-14159 Aux Id: ERL-340

+ + +

+ Fix suspension of schedulers when generating a crashdump.

+

+ Own Id: OTP-14164

+ + +

NIF resources was not handled in a thread-safe manner + in the runtime system without SMP support.

+

As a consequence of this fix, the following driver + functions are now thread-safe also in the runtime system + without SMP support:

+

driver_free_binary()

 +

driver_realloc_binary()

 +

driver_binary_get_refc()

 +

driver_binary_inc_refc()

 +

driver_binary_dec_refc()

 + +

+ Own Id: OTP-14202

+ + +

+ Fix erlang:round/1 for large floating point + numbers with an odd absolute value between (1 bsl + 52) and (1 bsl 53). The result was falsely + calculated as the next higher even number even though all + integer values up to (1 bsl 53) can be represented + as floats with full precision.

+

+ Own Id: OTP-14227

+ + +

+ Add size of literals to module code size in crash dump + and (l)oaded command in break menu like it used to + be before OTP-19.0.

+

+ Own Id: OTP-14228

+ + +

+ Fix potential bug in enif_send when called without + a process context and with argument msg_env as + NULL.

+

+ Own Id: OTP-14229

+ + +

+ Fix bug where passing an appendable binary to + erlang:port_control() could crash the emulator.

+

+ Own Id: OTP-14231

+ + +

+ Receive expressions with timeout in the Erlang shell + could cause a VM crash.

+

+ Own Id: OTP-14241 Aux Id: ERL-365

+ + +
+ + +
Improvements and New Features + + +

+ A received SIGTERM signal to beam will generate a + 'stop' message to the init process and + terminate the Erlang VM nicely. This is equivalent to + calling init:stop/0.

+

+ Own Id: OTP-14085

+ + +

+ Workaround for buggy Android implementation of + PTHREAD_STACK_MIN causing build of runtime system + to crash on undeclared PAGE_SIZE.

+

+ Own Id: OTP-14165 Aux Id: ERL-319

+ + +

+ Add configure option --without-thread-names that removes + the naming of individual emulator threads.

+

+ Own Id: OTP-14234

+ + +

+ Add warning in documentation of zlib:deflateInit/6 + about option WindowsBits values 8 and -8.

+

+ Own Id: OTP-14254 Aux Id: ERL-362
