mnesia: Check nodes after protocol negotiation
OTP-12473
|
|
During Mnesia startup, after protocol negotiation, the list of connected
nodes is written to "recover_nodes". This list is later used to merge
the schema.
If Mnesia was stopped on a remote node between the protocol negotiation
and the moment the list is stored in "recover_nodes", the remote node
is still considered running: the value of "recover_nodes" stored during
mnesia_down/1 is overwritten. Therefore, this node may be used to
acquire a write lock on the schema in order to perform the merge. In
this case, the remote node never answers to the lock request and Mnesia
hang forever (application:start(mnesia) never returns).
To fix the problem, we check the list one last time and remove from it
all nodes where Mnesia is stopped. And because there is still a chance
for missing mnesia_down event, handle_cast({mnesia_down, ...}, ...)
writes to recover_nodes again, in addition to mnesia_down/1.

{index, [2]} refers to #person.name rather than #person.address, which
caused a little confusion in #erlang today.
{index, [4]} is the correct "hard coded" field for #person.address.

If a DCD dump is desired on-demand, use the function
mnesia_controller:snapshot_dcd(Tables). Tables must be a list of
tables that have a local disc_copy, otherwise an error will be
returned. Once the operation actually executes, any table that doesn't
have a local disc_copy is ignored.
Specifically, the dump_log worker record has been changed to allow an
arity-0 fun instead of the default log dump. This fun will be executed
as if it were a normal log dump, and must return 'dumped'. This could
also be used to e.g. insert a backup operation between log dumps.
|
|
Setting the new Mnesia parameter 'dump_disc_copies_at_startup' to
'false' will completely disable the DCD dumping while tables are being
loaded. If it is set to 'true' (the default), the same test will now
be performed as for normal dumps, i.e., using the 'dc_dump_limit'
parameter. Previously, the test performed at load time was different
from the one used at runtime, and caused a lot of unnecessary dumping
which slowed down the startup.

By doing an abort, the create_table can be restarted
if a node go down during the transaction.

Optimize tid lock table
OTP-11981
|
|
By making the ets table mnesia_tid_locks an ordered set instead of a
bag, the time for inserting locks for a transaction with large number
of locks is reduced significantly.

can not be forced loaded.

Be sure to gather release_tid msgs even though we have a mnesia_down

Most dependencies introduced are exactly the dependencies to other
applications found by xref. That is, there might be real dependencies
missing. There might also be pure debug dependencies listed that
probably should be removed. Each application has to be manually
inspected in order to ensure that all real dependencies are listed.
All dependencies introduced are to application versions used in
OTP 17.0. This since the previously used version scheme wasn't
designed for this, and in order to minimize the work of introducing
the dependencies.

|
Ensure all are "normal" versions according to the new version scheme
introduced in OTP 17.0

For performance reasons the file data is not synced to disk in mnesia,
data loss can happen between each dump.
mnesia:dump_log() can be used explicitly to ensure data is written to disk.
But that can take a long time, so mnesia:sync_log() which just
sync the log have been added.
