* dgud/mnesia/try-catch:
mnesia: Replace catch with try-catch
|
|
Avoids building stacktraces where it is not needed and do
not mask errors, i.e. only catch the relevant classes in each try.
|
|
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.

Mainly to correctly clear dets tables. It may also be faster to use
the dedicated functions.

This could happen on ram_copies tables.
|
|
That caused a 'log_header' entry to added to the disc_copies tables.
