Instead of GncOptionUIType, mostly. We still need to do that to tell apart
commodities and currencies from other QofInstances.
Allows compile-time dispatch for most types.
And use serialize to create values for gnc:generate-restore-forms and both
of them for the meat of the stream functions.
This fixes in particular QofInstance serialization where passing the
option value directly to scheme format resulted in a notation about
a swig pointer instead of the desired GUID string or commodity namespace
and mnemonic strings.
This can be used to keep both in sync in the period between
initial migration and eventual obsolence.
Note only non-obsoleted, migrated preferences are tracked.
We don't want to resync preferences that have been
obsoleted (reset). That would nullify the whole idea
of making them obsolete for future removal.
This commit only adds the mapping, synching will follow in a future
commit.
'deprecate' is technically a noop. It serves to remind maintainers
the 'deprecated' preference is to be obsoleted in the next major
release.
'obsolete' goes one step further in that it will cause gnucash to reset
the preference, effectively clearing the value stored in the preferences
backend. This is the final phase of a preference. Following this it
will be completely removed from the GSettings schema in the next
major release.
Notes
* 'deprecate' and 'migrate' are related. Both are a reminder the
preference is to be obsoleted in the next major release. 'deprecate'
does only that though while 'migrate' will also trigger a copy of
the old value to a new location in the databse.
* This commit readds a couple of preferences that had been removed
in the past to be able to properly obsolete them (and to test
the obsoleting code)
This commit mostly changes descriptions and variable names to
use the more generic terms 'transformations' or 'conversions'.
'migration' is only one possible transform, future commits will
add others.
There are no functional changes in this commit other than
a logic inversion in parse_one_release_node. It now checks
for nodes named 'migrate' rather than for nodes not named
'migrate' (the code is adapted accordingly to match this
logic change).
We had hardcoded HAVE_HTMLHELPW to always be true so the fallback
code that's only reached when it is false was never reached.
Time to drop this dead code.
This makes sure all schema changes are in effect before
the first consumer can query them. For example this will
prevent a one-time re-occurrence of the tip of the day dialog
the first time the new migrations are run.
The rules for migration are read from an xml file. This file was
prepared in a previous commit. Future settings 'data model' changes can
reuse this code by simply adding migration rules in the xml file.
This replaces the hardcoded rules that were currently in place to
migrate a few settings from 2.6 and older to 3.0. These rules are no
longer meaningful as we require users to migrate from one major release
series to the immediate next one. So by the time the new migration rules
in this commit are applied by users they should already have run gnucash
3.x at least once. That run should have taken care of the pre-3.0
migration actions.
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.
significantly
Modify the DEBUG and PINFO macros to return unless qof_log_check is
true. Replace almost all direct calls to g_debug and g_message with
DEBUG and PINFO respectively.
Track the highest logging level sent to qof_log_set_level to provide a
short-circuit return in qof_log_check. Remove setting GNC_MOD_TESTS to
QOF_LOG_DEBUG so that the short-circuit threshold isn't defeated by
always being DEBUG.
Net result: 33% improvement in xml load times.
Removing the only use, an example in hello-world.scm. GnuCash doesn't
use this value in any of its own report options and the feature will
be removed in GnuCash 5.

From a Scheme alist. The vector can be used to find the scheme symbol
as a direct lookup, which isn't possible with an alist, and can be
searched for the Scheme symbol match more quickly than an alist can.
