The duplication could happen when the destination book was not set
to be used for autocompletion. Always checking the destination
book, and check it as the first, will not do unnecessary tests
in other books and will make sure that the contacts are not
blindly added there.
This partly fixes bug #721712 (Writeable calendars can report
as read-only after open), because the EClientCache always returns
the same EClient, which has internal properties properly updated
(at the second and following calls).
A simple Evolution run and move between all views means creation of
more than 100 GSettings objects, with only a bit more than 10 schemas.
Reusing the objects should have a positive impact on a performance too.
This is a follow-up for the previous commit, where e_signal_connect_notify*()
functions had been added. Due to a different callback and user data being
attached to the 'notify' signal, the g_signal_handlers_*() functions do not
work properly, thus these e_signal_connect_notify*() functions need
a different way for a signal handler disconnect.
A side-change was done in e-settings-web-view-gtkhtml.c, checking for a real
key change from GSettings.
This is related to bug 698275, which did not cover all cases.
The problem here is that the dconf can in certain situation claim
that everything changed (path "/" changed), which GSettingsBinding
propagates to a GObject property unconditionally and GObject's
property setter (g_object_set_property()) also notifies about
the property change unconditionally, despite the real descendant
property setter properly checks for the value change. After all
these false notifications a callback on "notify" signal is called
and possibly an expensive operation is run.
Checking whether the value really changed helps in performance, for
which were added new e-util functions:
e_signal_connect_notify()
e_signal_connect_notify_after()
e_signal_connect_notify_swapped()
e_signal_connect_notify_object()
which have the same prototype as their GLib counterparts, but they allow
only "notify::..." signals and they test whether the value really changed
before they call the registered callback.
The GtkImageView didn't receive any change for the past two years,
and since Evolution uses WebKitGTK the plugin lost its value. The same
can be done with WebKit too, in some extent, once someone implements it.
The "dialog-apply" icon is not from a set of standard icons, thus
it cannot be used, which I overlooked yesterday. With its drop are
also dropped other button icons in itip-formatter.
The missing icon made EStockRequest "panic" which effectively broke
page rendering for WebKit - the rendering was never finished.
This makes the code free of Coverity scan issues.
It is sometimes quite pedantic and expects/suggests some
coding habits, thus certain changes may look weird, but for a good
thing, I hope. The code is also tagged with Coverity scan
suppressions, to keep the code as is and hide the warning too.
Also note that Coverity treats g_return_if_fail(), g_assert() and
similar macros as unreliable, and it's true these can be disabled
during the compile time, thus it brings in other set of 'weird'
changes.
Nudging EPlugin closer to full removal.
Nothing in Evolution uses this anymore and 3rd-party plugins should be
using EShell's "event::ready-to-start" signal or else GApplication's
"startup" signal.
The returned UID array now has a built-in "free" function for its
elements and should be released by callers with g_ptr_array_unref()
rather than em_utils_uids_free() or some equivalent.
e_mail_reader_get_folder() does not return a new CamelFolder reference,
yet mail_to_event() was acting as though it does. This caused a crash
after the function ran and Evolution tried to use the folder again.
Truth be told, e_mail_reader_get_folder() really *should* return a new
reference to ensure the CamelFolder is not finalized while it's in use.
But we would need to rename the function to e_mail_reader_ref_folder()
to reflect the change in semantics, and I suspect the function is used
in a great many places.
