/** @addtogroup TransLog Transaction Logging
|
|
The transaction logging mechanism provides a very simple,
|
|
low-level logging of user input to a file. The goal of
|
|
the transaction logger is to provide mechanism of last resort
|
|
for recovering lost user data in the event of a crash.
|
|
|
|
Ideally, the storage backends should provide a robust journaling,
|
|
logging and crash-recovery mechanism. But just in case they
|
|
don't, or it didn't work, this mechanism provides a "Plan B"
|
|
by providing a low-tech, fool-proof, simple logging system
|
|
that can be used to recover user input.
|
|
There are some simple command-line tools that will read a log
|
|
and replay it.
