Rewrite the code to measure and print elapsed time instead of just
printing timestamps for the start and stop of each operation.
|
|
Use erlang:unique_integer/1 instead.
|
|
Use erlang:monotonic_time/1 instead of now/0.
|
|
Use erlang:timestamp/0 instead now/0 when seeding the random
number generator.

* sverk/ets-grow-faulty-assert/OTP-12647:
erts: Fix ets bug in debug VM
|
|
Symptom: ASSERT(segtab[seg_ix] == NULL) in alloc_seg() fails.
Remedy: Make sure we set segment pointer to NULL in free_seg()
even when we switch to smaller segtab.

stdlib: Make memcheck in ets_SUITE less sensitive

Certain error conditions could leave an open file descriptor.

by removing slave node creation and instead create remote pids, ports and refs
synthetically using binary_to_term.
Memory leak checks were sometimes failing due to mutating system ETS tables
caused by slave node communication.

A large 64-bit immediate number will be stored as SMALL_BIG_EXT by ETS
compressed format. When uncompressing, the SMALL_BIG_EXT was first
decoded as as bignum (by bytes_to_big) and then turned into a small
(by big_norm). This works for normal "binary_to_term" as
decoded_size() over-estimates the needed heap size. But for ETS no
over-estimation is done as the real term size is known and stored in
DbTerm.
Fixed by preventing bytes_to_big() from writing bignum digit when the
number is seen to fit in an immediate.

Also added more information when waiting for test proc to die

A number of memory allocation optimizations have been implemented. Most
optimizations reduce contention caused by synchronization between
threads during allocation and deallocation of memory. Most notably:
* Synchronization of memory management in scheduler specific allocator
instances has been rewritten to use lock-free synchronization.
* Synchronization of memory management in scheduler specific
pre-allocators has been rewritten to use lock-free synchronization.
* The 'mseg_alloc' memory segment allocator now use scheduler specific
instances instead of one instance. Apart from reducing contention
this also ensures that memory allocators always create memory
segments on the local NUMA node on a NUMA system.
