Should fix once for all #24210
* idl/evolution-calendar.idl: changed the notifyObjUpdated method
of the QueryListener interface accept a list of UIDs.
* cal-client/query-listener.[ch] (impl_notifyObjUpdated): likewise for
the QueryListener class.
* cal-client/cal-query.c (obj_updated_cb): changed to adapt the
multiple-id's received in the QueryListener class' signal to the
one-by-one update notification of the public CalQuery class, thus
keeping the changes needed for this minimal.
* pcs/query.c (add_component, start_cached_query_cb): changed to
send sequences of UIDs.

More fixes for #24210
* pcs/query.c: added list of cached queries and changed the Query
class to work with several listeners, not only one.
(query_init): initialize new members.
(query_destroy): free new members.
(add_component, remove_component, parse_sexp, match_component,
process_components_cb): notify all listeners.
(notify_uid_cb, start_cached_query_cb): implemented integration of
cached queries.
(query_new): search the query in the cache before creating a new
one. And if we create a new one, store it in the cache.

(query_backend_destroy): destroy the static GHashTable if empty.
(foreach_uid_cb): call object_updated_cb, which does everything.
* pcs/query.c: make use of the new QueryBackend class.
(query_init): initialize new private structure member.
(query_destroy): clean up new member, without freeing it, since it is
managed internally in query-backend.c.

2001-11-09 Federico Mena Quintero <federico@ximian.com>
(committed by Damon)
Fix bug #14699.
* pcs/query.c (QueryState): Added a state QUERY_WAIT_FOR_BACKEND
to indicate that the query is not populated as we are waiting for
the backend to be opened.
(query_init): Start in the QUERY_WAIT_FOR_BACKEND state.
(query_destroy): Only disconnect from the backend if we are in a
state that implies that we are connected to its signals.
(query_construct): If the backend is already loaded, immediately
set the state to QUERY_START_PENDING.
(backend_opened_cb): Disconnect from the backend's "opened"
signal. Set the state to QUERY_START_PENDING.
(match_component): We can now only match components if the query
is in progress or if it is done. Assert to that effect, and do
not ensure_sexp().
(match_component): Do not check for a nonexistent component using
g_return_if_fail(). Also, there is no need to ref/unref the
component.
(backend_obj_updated_cb): Assert to the effect of our state.
(backend_obj_removed_cb): Likewise.
(parse_sexp): Renamed from ensure_sexp(). Assert that the query
has not started. Do not disconnect from the backend's signals
here, since we have no connections.
(start_query_cb): Set the state to QUERY_IN_PROGRESS here instead
of in populate_query().

2001-10-31 Federico Mena Quintero <federico@ximian.com>
* gui/gnome-cal.c (dn_query_obj_updated_cb): If a query is not in
progress, just retag the whole thing. An event may change dates
and tag_calendar_by_comp() would not know how to untag the old
dates. Fixes bug #10220.
* pcs/query.c (start_query_cb): Connect to the backend's
"obj_updated" and "obj_removed" signals here instead of in
query_construct(). If a query is started while another one is
notifying of an update, these signal connections would get appened
to the running signal (the one that triggered the notification
about an update) and the new signal handlers would also get
called. We are really not interested in updates before we
populate the query, because we'll catch the changes anyways.

2001-10-22 Damon Chaplin <damon@ximian.com>
* idl/evolution-calendar.idl: added setDefaultTimezone() method.
* pcs/cal-backend.c (cal_backend_get_default_timezone):
(cal_backend_set_default_timezone): new functions to call class
methods.
* pcs/cal-backend-file.c: lots of changes to handle the default
timezone and use it.
* pcs/query.c: use the default timezone.
* gui/dialogs/task-details-page.c (date_changed_cb): initialized
completed_tt.
* gui/dialogs/event-page.c: changed it to handle DATE values. The
'All Day Event' checkbox is only set now when the DTSTART and DTEND
are DATE values.
* gui/dialogs/comp-editor-util.c (comp_editor_free_dates): free the
CalComponentDateTime structs as well.
* gui/e-tasks.c: set the default timezone on the server.
* gui/tag-calendar.c:
* gui/gnome-cal.c:
* gui/e-week-view.c:
* gui/e-day-view.c: updates to handle DATE values.
* gui/e-calendar-table.c (date_compare_cb): updated to use the new
ECellDateEditValue values, so it now works.
(percent_compare_cb): updated to use GPOINTER_TO_INT values.
(e_calendar_table_init): use an ECellPercent for the percent field
and an ECellDateEditText for the date fields.
* gui/comp-util.c (cal_comp_util_compare_event_timezones): return TRUE
if the DTSTART or DTEND is a DATE value. We don't want to show the
timezone icons for DATE values.
* gui/comp-editor-factory.c (resolve_pending_requests): set the default
timezone on the server.
* gui/calendar-model.c: major changes to support sorting properly.
For date and percent fields we now use subclasses of ECellText, so
we don't use a char* as the model value. For the percent field we now
use a GINT_TO_POINTER. For the date fields we now use a
ECellDateEditValue* as the value.
* gui/calendar-config.c (calendar_config_configure_e_cell_date_edit):
set the timezone and use_24_hour flags of the new ECellDateEditText.
* conduits/todo/todo-conduit.c (pre_sync):

* cal-util/test-recur.c: try to handle timezones in the iCalendar
file properly, and updated to pass default timezone.
* cal-util/cal-util.c (cal_util_generate_alarms_for_comp):
(cal_util_generate_alarms_for_list): added default timezone argument.
* cal-util/cal-recur.c: changed many of the functions to take a default
timezone, to use to resolve DATE and floating DATE-TIME values.
* cal-client/cal-client.c (cal_client_set_default_timezone): new
function to set the default timezone.
(cal_client_ensure_timezone_on_server): new function to ensure that
a given timezone is on the server.
* gui/e-cell-date-edit-text.c: new subclass of ECellText to display
and edit a date value.
* cal-util/cal-recur.c (cal_obj_byday_expand_monthly): changed week_num
to -week_num when calculating the weeks to go back from the end of the
month for things like BYDAY=-2WE. Fixes bug #11525.
(cal_recur_generate_instances_of_rule): only go up to MAX_YEAR (2037).
We can't really handle anything past that anyway.
(cal_recur_ensure_rule_end_date): initialize cb_date.end_date to 0,
so if the RULE doesn't generate COUNT instances we save 0 as the
time_t.

(itip_address_free): free single address
(itip_addresses_free): use above
(comp_limit_attendees): limit the number of attendees to one, the
user
(comp_sentby): set the sentby parameter if the user is not the
organizer
(comp_minimal): remove extraneous info for send (for refresh and
declinecounter)
(comp_compliant): remove all alarms, do various things to make the
components comply with itip spec based on method
(itip_send_comp): use comp_compliant method
* gui/itip-utils.h: new protos
* gui/e-itip-control.c: rescan the component when necessary
(get_next): don't get stuck in infinite loop if there are no
viewable components
(e_itip_control_set_data): if there are no viewable components,
spit an error message
* gui/dialogs/meeting-page.h: tidy
* gui/dialogs/meeting-page.c (meeting_page_fill_widgets): use
organizer's cn if possible
(other_clicked_cb): no longer doing the sent by stuff directly,
hide more widgets

* cal-util/cal-component.c (cal_component_rescan): have the comp
rescan its libical component (for when you change things directly)
(free_icalcomponent): take a param on whether to free the
component or just clean up the mappings
(cal_component_has_attendees): util function
* cal-util/cal-component.h: new protos
svn path=/trunk/; revision=13525
2001-09-17 Damon Chaplin <damon@ximian.com>
* gui/calendar-model.c: added a timeout to refresh the list every
10 minutes. Not ideal, as the user may be editing a task when it gets
refreshed.
(adjust_query_sexp): use the 'completed-before?' operator to filter
out tasks according to the config settings.
* gui/dialogs/task-details-page.c (task_details_page_fill_widgets):
added support for the 'Completed' date. This code must have got lost
somewhere, as it used to work.
(date_changed_cb): set the priv->updating flag while updating the other
widgets.
* pcs/cal-backend-file.c (cal_backend_file_update_objects): made sure
we freed the components.
* pcs/query.c (func_completed_before): added 'completed-before?'
operator.
* gui/calendar-config.c (calendar_config_configure_e_cell_date_edit):
don't set the lower & upper hour. Use 0-24 like the EDateEdit does.
* gui/dialogs/cal-prefs-dialog.c (cal_prefs_dialog_show_config): set
the 12/24-hour time format options sensitive only if we support both.
* gui/calendar-config.c (config_read): if the locale doesn't define
'am' and 'pm' strings then we must use 24-hour format.
* gui/calendar-commands.c (calendar_set_folder_bar_label): don't
translate the '%d' as it doesn't make much sense. Resolves bug #8027.
svn path=/trunk/; revision=12925
2001-08-28 Federico Mena Quintero <federico@ximian.com>
Fixes bug #7879, a query may receive an update notification from
the backend before the query itself gets populated.
* pcs/query.c (ensure_sexp): New function; ensures that the esexp
is created and notifies of parse errors. It is the bulk of
start_query_cb() but put in a separate function so that we can
share it elsewhere.
(start_query_cb): Use ensure_sexp().
(process_component_cb): Oops, notify of a successfully finished
query.
(match_component): Call ensure_sexp(). This function can be
called by the backend notification callbacks before the query is
populated, so we need to make sure the esexp exists here.
svn path=/trunk/; revision=12509
2001-08-21 Damon Chaplin <damon@ximian.com>
* pcs/query.c (func_is_completed): added new e-sexp operator. We
don't currently use it though.
* gui/dialogs/cal-prefs-dialog.glade: Changed '_Overdue' to 'O_verdue'
since we have an '_Other' notebook tab. Added '_Hide' accel.
* gui/dialogs/cal-prefs-dialog.c: hooked up config options to dialog.
* gui/calendar-config.c: added config options for hiding completed
tasks.
* gui/e-week-view-event-item.c (e_week_view_event_item_draw):
* gui/e-day-view-top-item.c (e_day_view_top_item_draw_long_event):
* gui/e-day-view.c (e_day_view_reshape_long_event): added 2 pixels
extra space between icons and text for long events, and 1 pixel space
between icons in all events.
(e_day_view_realize): changed the background color to match the
EGrayBar in the shell.

2001-08-09 Damon Chaplin <damon@ximian.com>
* pcs/cal-backend.c (cal_backend_get_object_component): added new
backend method to get the component given a UID.
* pcs/cal-backend-file.c (cal_backend_file_get_object_component):
added implementation of above virtual method.
* pcs/query.c (match_component): use the new backend function to get
the CalComponent rather than the string. This avoids converting all
the calendar components to strings and parsing them back into
components for every query! (That wasn't a good idea, was it ;)
* gui/e-week-view.c:
* gui/e-day-view.c: use a timeout handler to layout the events,
to avoid doing a layout for each event we get from a query.
* gui/print.c (print_day_add_event):
* gui/e-day-view.c (e_day_view_add_event): set start_row_or_col and
num_columns to 0. They are guint8's.
* gui/e-week-view.c (e_week_view_free_events): hide all the jump
buttons. Fixes bug #5946.
* gui/calendar-commands.c (calendar_set_folder_bar_label): added the
day numbers for the month view.
* gui/dialogs/recurrence-page.glade: changed "_Delete" to "_Remove",
since it clashed with "_Add". Also added underlined accelerators for
the recurrence radio buttons. Note that none of these accelerators
actually work at present, due to the way we are using .glade files
for each notebook page. I need to add a bug about this.
Also, the "_Action" menu doesn't popup when I press Alt+A, even though
the "_File" menu does popup when I press Alt+F. Strange.
* pcs/cal-backend-file.c (cal_backend_file_get_timezone_object):
removed debug msgs.

The calendar search bar widget now includes a drop-down menu of
available categories.
* pcs/query.c (func_has_categories): Handle one and only one #f
value as meaning "unfiled", for components that have no categories
at all.
* pcs/cal-backend-file.c (open_cal): Duh, do not notify here about
changed categories since at this point we don't have any clients

* gui/cal-search-bar.h (CalSearchBarClass): New signal
"category_changed".
* gui/cal-search-bar.c (cal_search_bar_construct): Add a drop-down
menu for the list of categories.
(search_option_items): Removed the "Has category" option, since we
now have the drop-down menu instad and it would be confusing to
have both options.
(regen_query): Likewise. Also, this function is now the old
cal_search_bar_query_changed() and is shared by that very function
and by the callback from the drop-down menu.
(notify_query_contains): Include the sub-sexp for the categories.
(cal_search_bar_set_categories): New function.
(cal_search_bar_get_category): New function.
(categories_selection_done_cb): Emit the "category_changed" signal.
* gui/e-tasks.c (obj_updated_cb): Removed function since it did
not do anything; all updates are handled by the CalendarModel.
(obj_removed_cb): Likewise.
(ETasksPrivate): Removed the fields for the categories option
menu, since now it is in the ESearchBar.
(search_bar_sexp_changed_cb): Use calendar_model_set_query()
directly here, as we do not need to frob the sexp anymore.
(update_query): Removed.
(client_categories_changed_cb): New callback.
(search_bar_category_changed_cb): New callback.
(e_tasks_new_task): Set the default category on the component to
the one that is selected in the search bar.
(e_tasks_on_filter_selected): Removed.

(e_tasks_setup_view_menus): Sanitized not to sink objects wildly.
(e_tasks_discard_view_menus): New function.

"categories_changed" signal since this is handled in the Wombat
now.
* gui/calendar-model.c (calendar_model_get_categories): Removed.
(calendar_model_set_value_at): Do not collect the categories.
(query_obj_updated_cb): Likewise.
(calendar_model_collect_categories): Removed.

* pcs/cal-backend.[hc]: added virtual method to get a VTIMEZONE
component given a TZID. We need this to resolve TZIDs when expanding
an event using cal_recur_generate_instances() in query.c.
* pcs/cal-backend-file.c (cal_backend_file_get_timezone): implemented
virtual method.
(cal_backend_file_update_object): fixed bug, kind -> child_kind.

resolving TZIDs. The other way didn't work anyway, as we didn't have
the entire VCALENDAR with VTIMEZONEs in it.
* gui/dialogs/recurrence-page.c (init_widgets):
(make_ending_until_special): moved the call to
e_date_edit_set_get_time_callback() from init_widgets to
make_ending_until_special(), since that is where the widget gets

Engine for live queries to calendars. A query object watches a
CalBackend in the PCS and is otherwise completely separate from
it; backends need to do nothing to support live queries. Right
now we have the following functions:
(get-vtype)
Returns a string indicating the type of component
(VEVENT, VTODO, VJOURNAL, VFREEBUSY, VTIMEZONE,
UNKNOWN).
(occur-in-time-range? START END)
START - int, time_t start of the time range
END - int, time_t end of the time range
Returns a boolean indicating whether the component
