* mikpe/mnesia-openlog-emfile:
mnesia: don't delete log file on emfile error
OTP-12807
|
|
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.

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.

This avoids the situation where mnesia could dump a very large ets table in
its entirety into the message queue of the disk_log process, causing memory
blowup and choking the disk logger.

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

Resolve name clash with auto-imported BIF error/2.
