This was a remaining thing from the 'Make calendar views non-UI-blocking'
work, to show progress of views in UI. This is currently done by a spinner
beside source's name in the ESourceSelector and a tooltip above that row.
The Calendar, Memos and Tasks views use to do D-Bus calls to
the backends on the main (UI) thread, which could result in UI
freezes, until the operation was done on the backend (and server)
side. This commit fixes that by invoking the operations in
a dedicated thread. It has few additional advantages too:
- operations can be cancelled
- proper error reporting to a user
- less code duplication between the views for common operations
There had been fixed some performance issues when selecting/unselecting
sources in the source selector as well.
The icons at the search bar, to search forward, backward and stop
searching were too large, which didn't look good. This makes them
smaller, though even here can be seen a little gap around
the images in the buttons which might not be there ideally.
Similar to GObject::notify, the GSettings::changed can be emitted
even if a key didn't change. It's up to the user (aka evolution)
to test for real changes, thus let's do it. It may have certain
performance positive impact too.
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.
This ports the following two function calls throughout Evolution:
• e_categories_get_list() to e_categories_dup_list()
• e_categories_get_icon_file_for() to e_categories_dup_icon_file_for()
It necessarily changes some internal e-util API:
• e_util_get_searchable_categories() to
e_util_dup_searchable_categories()
This bumps the EDS requirement to 3.13.1.

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.
EShellView no longer needs help from subclasses other than getting
the needed GalView subclasses registered.
A nice side-effect of this is EShellView subclasses can now use the
G_DEFINE_DYNAMIC_TYPE macro.
No longer needed. Instead, use g_type_ensure() to ensure the necessary
GalView subclasses are registered in the GType system before loading a
GalViewCollection. Best place to ensure types is from GClassInitFunc.
EShellView now holds a reference to the active GalViewInstance. Where
applicable, the EShellView subclass is responsible for keeping this up
to date when the sidebar selection changes.
Holding a reference allows EShellView to implement common actions like
"Save Current View" directly instead pushing it on to subclasses.
New functions:
e_shell_view_get_view_instance
e_shell_view_set_view_instance
e_table_specification_new() now takes a table specification filename and
a GError and parses the file as part of instance creation. If a file or
parse error occurs, e_table_specification_new() returns NULL.
This replaces e_table_specification_load_from_file().
New functions:
e_table_specification_get_filename()
Removed functions:
e_table_specification_load_from_file()
I don't remember why E_TASK_TABLE_DEFAULT_STATE was needed when
e-calendar-table.etspec already specifies a default ETableState.
Some of the column numbers it was referencing weren't even valid.
Removing it seems to make no difference in Evolution.
I don't remember why E_MEMO_TABLE_DEFAULT_STATE was needed when
e-memo-table.etspec already specifies a default ETableState.
Removing it seems to make no difference in Evolution.
The shortcuts Ctrl+C/V/X are used for whole calendar items
copy/paste/cut, not for text when editing event details inline, either
in a day/week view or in a list view. By tracking the is-editing property
of respective cell editor and using it when enabling/disabling clipboard
actions makes the respective text operations work as expected.
This is another source of crashes after creating and destroying a second
shell window. The signal handler was left connected with the destroyed
shell window as the closure.
This fixes a bug in the old implementation where the application could
crash after a second shell window was created and destroyed, because a
signal handler with the destroyed shell window as the closure was left
connected.
But moreover this simplifies the implementation by using a property
binding plus transform function instead of juggling signal handlers,
and also adds code comments where things get a little tricky.
Removed (now unused) functions:
e_shell_window_get_toolbar_new_prefer_item
e_shell_window_set_toolbar_new_prefer_item
Call e_source_selector_update_all_rows() after connecting to the
selector tree model's "row-changed" signal. This will ensure the
appropriate ECalClients get loaded into the ECalModel.
This fixes the bug where opening a second Tasks window shows no
content until one of the sidebar items is fiddled with.
