Optimise ext table dumping
OTP-15588
|
|
Mnesia should always use the local context if available
OTP-15550
|
|
The original algorithm first grouped ops in a commit by ext engine
type via folding over the list with orddict:append/3, that resulted in
an O(n^2) algorithm.
However, grouping the ops is not needed, the ops can be dispatched to
insert_op/6 one-by-one, after looking up the storage semantics of
their respective engine. This is a much cheaper algorithm, assuming
looking up the storage semantics is cheap (which should be).

Do not read from (set | order_set) source table if the content is
already in the transactional context (i.e., a previous write/delete).

Index records for bag tables with ram_copies was not deleted
after "real" objects where deleted and thus a memory leak.

* dgud/mnesia/add_table_copy_ram/OTP-15226:
Relax add_table_copy restriction
|
|
Allow to add replicas even if all other replicas are down when the
other replicase are not stored on disk.
|
|
Setting master_nodes to a node with ram_copies replica and
that node had not loaded the table, could cause it load an
empty table, even though (non master) nodes had disc_replicas.
This meant that tables where unexpected empty after multiple failures
happened. When this happen do not load the table and wait for user
to force_load it on some node, preferably with a disk copy.

I did not find any legitimate use of "can not", however skipped
changing e.g RFCs archived in the source tree.

Fix a bug, when delete_object was deleting the record if it was written
in the same transaction even if it was written to a different value.
To verify:
%% Create a set table
mnesia:create_table(foo, []).
%% Write and delete_object in transaction
mnesia:transaction(fun() ->
mnesia:write({foo, bar, one}),
mnesia:delete_object({foo, bar, not_one})
end).
{atomic, [{foo, bar, one}]} = mnesia:transaction(fun() -> mnesia:read(foo, bar) end).
Added a section to isolation tests to check for non-matching delete_object
requests.

make erlang:process_info/1 not retrieve messages
|
|
process_info/1 retrieves a number of properties related to a process,
including the list of messages in its mailbox. This is potentially
unsafe if the target process has a large number of queued messages:
- there is no a priori upper bound on the amount of memory being
allocated to hold that list, and
- the loop to retrieve the messages is uninterruptible, so the
Erlang scheduler where this executes blocks for the duration
We've seen process_info/1 bring down heavily loaded nodes on more
than one occasion. At least once it appeared to have blocked the
Erlang heart process from executing, causing the external heart to
kill the VM.
Consequently this removes 'messages' from the list of process_info
tags to retrieve for process_info/1. Note that process_info/1 still
retrieves 'message_queue_len', and process_info/2 can still retrieve
'messages' when asked to.
A few places in the OTP libraries need minor adjustments, since they
want 'message_queue_len' but compute it from the length of the list
of messages.

Take care of the call of erlang:get_stacktrace() in
module mnesia_lib.

The remaining call (in module mnesia_lib) is taken care
of in the following commit.
