There is a bug in system_info BIF causing a crash if
erts_get_cpu_topology_term fails. The fix comes with a non-regression
test.
|
|
The following test suites now work:
send_term_SUITE
trace_nif_SUITE
binary_SUITE
match_spec_SUITE
node_container_SUITE
beam_literals_SUITE
Also add a testcases for system_info({wordsize,internal|external}).

* egil/binary-gc:
Add documentation for binary heap size settings.
Add tracing capabilities for binary virtual heap
Add min heap size start options to beam and erl
Improve binary garbage collection
OTP-8370 The default settings for garbage collection of binaries has been
adjusted to be less aggressive than in R13B03. It is now also
possible configure the settings for binary GC. See the
documentation for spawn_opt/2-5, erlang:system_info/1,
erlang:system_flag/2, process_flag/2-3, erlang:trace/3, and the
documenation for erl for the new command line options +hms and
+hmbs.

The garbage collector in r13b03 is too aggressive in some cases. This
commit raises the level of default initial allowed binary garbage
(virtual heap for binaries) before collecting from 233 words to
46368 words (181 kB on 32-bit).
A new option, min_bin_vheap_size, has been added to spawn_opt,
system_flag and process_flag can be used to change the default values.
The option can also be used with system_info and process_info to
inspect the values.
For symmetry the option min_heap_size has been added to the above
functions where it was previously missing.
Add testcases for min_bin_vheap_size and min_heap_size for
functions process_flag/2, process_info/2, system_info/2 and
spawn_opt/2.
