make erlang:process_info/1 not retrieve messages
2018-03-10make erlang:process_info/1 not retrieve messagesMikael Pettersson
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.

Bad timing can cause retain messages to go to a new process if checkpoint name is reused directly and the checkpoints contain different tables. Ignore those messages instead of crash.

2017-12-14mnesia: Read schema user properties directlyDan Gudmundsson
Doing a proper transaction handling of user properties (in current implmenentation) caused schema_transactions to be quadratic which caused huge startup times for nodes with many tables since the merge schema is a schema_transaction. Do a direct read instead, cheap but implies that the plugin changes will not be visible until the changes are commited and cannot be used later in same transaction, which was possible before if undocumented functions where used.

The "root cause" error reason was lost when abort_write failed, e.g. file was already closed, and Mod:abort_write(..) returned an error.

This commit also adds a check to see that all files that are part of an xi:include also have part of XML_FILES and vice versa. It also fixes any applications where this was not true.
