History
Christian Stimming 92ea3ba8a6 Register speed-up for large files. 
The function qof_book_use_split_action_for_num_field gets called quite a
lot in each register display refresh (due to sorting all splits from
Split.x's xaccSplitOrder function), but it always used to use a KVP
lookup, which is rather expensive compared to accessing a gboolean member
variable.

To get rid of this cost, I had to remove the KVP lookup in this
simple-looking function. The pattern is this: A gboolean cache variable is
introduced, along with an isvalid flag. The lookup makes the expensive
KVP lookup once, then caches the value. The GObject property mechanism
offers a callback for when the setter was called, which is used to mark
the cached value as invalid. A parallel setter method (here:
qof_book_set_option) also just marks the cache as invalid. This covers
all setters, and the getters will use the cached value except for their
first invocation.

The NUM_FIELD_SOURCE feature was introduced in 2012 by the very large
commit 7cdd7372 and apparently its costs never were a problem
until the KVP lookup became more costly due to the std::vector
construction and destruction.

README 

This directory contains code for the accounting engine.
Its fairly clean but far from perfect, and it certainly
lacks advanced features.

There should be no GUI code in this subdirectory, and,
ideally, it should build cleanly and independently of 
any GUI elements or assumptions.

For design documentation, please see the file "design.txt",
and also, look at the header files carefully.  The documentation
for each routine is in the header files for that routine.
