Turns out the stream facet parser is really slow. Since we have a
well-constrained universe of input formats we don't really need that
overhead. This got a 33% improvement in loading a large SQLite database.
The first attempt to fix this, a17bc85a, doesn't work because the
boost::date_time constructor gets enough information in most cases to
generate a date, just not the one we expect. This change looks for '-' in
the fourth position and if it's there assumes iso-extended format, otherwise
it assumes delimiter-less ISO without the 'T', i.e. %Y%m%d%H%M%S.
This will avoid a ninja-build from picking up a config.h generated by the autotools build
(in the root build directory). Picking up the wrong config.h may lead to all kinds of
subtle issues if the autotools run was done with different options than the cmake run.
It is split into
- /libgnucash (for the non-gui bits)
- /gnucash (for the gui)
- /common (misc source files used by both)
- /bindings (currently only holds python bindings)
This is the first step in restructuring the code. It will need much
more fine tuning later on.
