Many heap fragments do no longer make the GC slow.
Even worse, we are not guaranteed that a yield will provoke a GC
removing the fragments, which might lead to a one-yield-per-bucket
scenario if the heap fragment(s) still remains after each yield.

causing erlang:memory to report too much ets memory.
|
|
|
|
as it's now only used for empty tables by ets:new/2.
|
|
|
|
by only allocating one FixedDeletion with the new "all" flag
instead of one FixedDeletion per slot.
|
|
* Remove all "mtraversal_" prefixes.
* Rename all local context variables as "ctx".
* Changed callbacks from function arguments
to members of new base context struct "match_callbacks_t"
* Remove unnecessary struct initializations "= {0}"

to be done after lock has been released.
|
|
Separate pseudo-deleted-flag from the hash value.
|
|
by using a cooperative strategy that will make
any process accessing the table execute delelete_all_objects_continue
until the table is empty.
This is not an optimal solution as concurrent threads will still
block on the table lock, but at least thread progress is made.

|
and not the name. For more sane named table semantics.
Applies to both select/1 continuation and trap context.
|
|
where argument 'list' is the first candidate (not list->next).
Also simplified db_first_hash().
|
|
There is no NULL check here !?
|
|
|
|
Besides being noisy, they were already defined by a global Unix-
specific header, causing the Windows build to fail if one forgot to
define them.

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

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.

Support hashing terms from NIF code
|
|
|
|
to replace macro ERTS_INTERNAL_BINARY_FIELDS
as header in Binary and friends.
|
|
DID_TRAP will read 'ret' even when error is returned.
Found by valgrind.
|

for temporary matchspec results.
ToDo: Would be even nicer if PAM could allocate and build
the ETS objects without extra copy_struct needed.
|
|
|
|
|
|
Preemptively fail operation with badarg if the replacement object
might have a different key.
|
|
|
|
Refactor existing solution into a common iteration loop parameterized
using stateful callbacks.
|
|
The existing implementation presented both
semantic inconsistencies and performance issues.

Also removed the body for CHECK_TABLES enabled by HARDDEBUG.
Removed quite useless check for hash,
but kept dead check code for tree.
|
|
to get rid of meta table lookup by integer (tb->common.id)
|
|
from process psd through all owned/fixed tables.
As meta_pid_to{_fixed}_tab maps to slot in meta_main_tab
which is planned for destruction.
In this commit we no longer seize table lock while
freeing the table (free_table_cont) as it's not needed
and makes the code a bit simpler. Any concurrent operation
on the table will only access lock, owner and status
and then bail out.

Instead of passing around a file descriptor
use a function pointer to facilitate more advanced
backend write logic such as size limitation or compression.

* sverker/ets-load-factor:
erts: Unify reduction count for ets:select
stdlib: Cuddle ets_SUITE for valgrind
stdlib: Fix ets_SUITE:smp_select_delete
erts: Tweak ets grow/shrink to keep up at contention
erts: Fix ets_SUITE:memory
erts: Suppress failed ETS memory checks
erts: Reduce ets hash load factor
erts: Enable a smaller first hash segment for ets
erts: Redesign ets with separate segment tables
erts: Remove unnecessary access of 'is_resizing'
erts: Add ErtsSizeofMember macro
erts: Add ErtsContainerStruct_ for array members
|
|
to be per object as the other select-variants
and not per table slot.
|
|
|
|
by simply asking for the size of struct ext_segtab
|
|
due to the grow/shrink hysteresis of the meta tables
|
|
for faster lookup/insert/delete
at the expense of about one word per object.
