As of ddc3f28899, gvalue_from_kvp_value()
takes a GValue pointer from the caller, which in some cases points to
memory on the stack. If that is the case and the code also hits the
default case in the switch statement, the unconditional g_slice_free()
call will attempt to free stack memory, causing the program to abort.
Fix by requiring the caller to always pass in a valid GValue pointer,
making the caller responsible for freeing it if necessary. This also
means that it is no longer necessary for gvalue_from_kvp_value() to
return a value, so make it a void function.
The root cause of which is that on recent releases of GLib (recent
meaning 2.66 in the current Debian stable!) g_type_instance_get_private
looks in the wrong place for the private data. When running the script
in question it returned NULL and since the code didn't check for a valid
pointer, it crashed.
So this change replaces all calls to g_type_instance_get_private with
the function [type_prefix]_get_instance_private() added in glib-2.36
except for two register2 files that have been removed from master; those
are ignored to avoid unnecessary merge conflicts.
If QofInstancePrivate has no collection then qof_instance_dispose() returns
without completing the rest of its dispose processes, skipping removal of
its type string from the string cache resulting in a reference count leak.
Change the check for a collection so that it only affects the call to
qof_collection_remove_entity().
Price Database dropping user:price-editor entries.
A wider problem: QofInstance was unmarking itself dirty as long as the
backend raised an error and unconditionally marking itself non-infant.
This matters because the SQL backend depends on infant status to decide
whether to do an insert or update query; either will fail if the infant
status is wrong.
The price editor dialog clones a price having only its commodity set and
GncSqlPriceBackend declines to save if the currency isn't set. Since the
instance marked itself non-infant even though it wasn't saved subsequent
commits tried to use an update query and since the price wasn't in the
table that inevitably failed.
Requiring that QofBackend::commit should doing the marking-clean
required implementing it in the backends where it wasn't already.
with the function/declaration that they substituted.
Note that this doesn't use the recommended new GObject creation macros
because the class names in libgnucash/engine don't follow the gnome
naming convention.
There are a very few left that need deeper study, but this gets
rid of most of the noise. For the most part it's just getting rid of
extra variables or removing an assignment that is always
replaced later but before any reads of the variable. A few are
discarded result variables.
There were several problems that broke the Imap Editor that have been
fixed due to kvp changes. The import-map-bayes entries were being added
to the tree view based on the number token entries squared. Retrieving
import-map entries resulted in an empty list and also deleting entries
from the tree view failed.
The template avoids the need to cast to and from void*, and adds flexibility to
the targeted function's signature.
test-stuff.h defines a macro, "failure" which is used as an identifier
in the standard IO library, so I moved any inclusion of test-stuff.h to
the last include position so that "failure" wouldn't be defined before
the IO library was included.
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.
