* mikpe/mnesia-openlog-emfile: mnesia: don't delete log file on emfile error OTP-12807
2015-05-31mnesia: don't delete log file on emfile errorMikael Pettersson
If the VM runs into the process' file descriptor limit when mnesia tries to open (not create) a disk_log file, the open fails with an emfile error. Mnesia misinterprets this as a corrupt file, deletes it, tries to create a new empty disk_log file, which also fails. The end result is a corrupt database on disk. Check for emfile errors and error out immediately without deleting the file in those cases.

'dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation' into maint * dumbbell/mnesia-hang-if-remote-stopped-after-proto-negotiation: mnesia: Check nodes after protocol negotiation OTP-12473
2015-02-10mnesia: Check nodes after protocol negotiationJean-Sébastien Pédron
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.
2015-01-18Fix index for #person.address in create_table/2Cian Synnott
{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.

2014-12-22Make Mnesia DCD dump behaviour available via APIUlf Wiger
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.
2014-12-22Make Mnesia DCD dump behaviour available via configurationUlf Wiger
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.
