This was ported from GConf, but GSettings doesn't work that way.
Settings locations are defined at compile time and can't be
relocated at run time (unless you make all of the settings
explicitly relocatable. That however is not how GSettings is meant to be
used.)
The latter is the prefix format prescribed by gsettings itself. The former never
was an issue until flatpak decided to not accept the shorter prefix when
requesting a settings migration from host system to flatpak sandbox.
In order to allow for migration, keep the old schema around in
org.gnucash.GnuCash.deprecated.gschema.in
While we're at it, make the new prefix an internal implementation detail.
There's no need for it to be visible to the rest of the gnucash code.
When the preference dialogue is loaded and options are set, the ones
with registered callbacks fire causing parts of Gnucash to be updated.
This was observed with gnc_split_register_load being executed 5 times
for each open register when the preference dialogue was loaded.
To overcome this, a couple of functions have been created to block and
unblock all registered prefs and used while the preference dialogue is
loaded.
The preference schema migration collects all schema mutations that can occur
when upgrading to a newer gnucash version. The old gconf to gsettings conversion is
integrated in this system as well. Newer schema mutations will happen based on version
number upgrades though.
The preference that got replaced is "use-theme-colors". Based on discussion in bug 746163
(https://bugzilla.gnome.org/show_bug.cgi?id=746163) and gnucash-docs PR#105
(https://github.com/Gnucash/gnucash-docs/pull/105) this has been replaced with
"use-gnucash-color-theme" with inverted meaning. The old option is kept around for one or
two major release cycles to allow seamless conversion.
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.
