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.
GTK+ uses (G_PRIORITY_HIGH_IDLE + 20) for redrawing operations, which is
actually a slightly lower priority than G_PRIORITY_HIGH_IDLE. Therefore
for our purpose, G_PRIORITY_HIGH_IDLE is sufficient.
This reverts commit 2b507716b2.
The commit contains not a single comment as to why these custom priority
values are being used. The rationale needs to be documented in the code,
either at each call point or preferrably at a centralized priority value
definition.
