Lars HenriksenandLukas Fleischer 99c7493cd5 Fix deletion of a multi-day recurrent appointment
When the selected day in the calendar is a continuation day (not the first day)
of such an appointment, deleting the occurrence does not work. The reason is
that the selected day, and not the first day of the occurrence, is added as an
exception day.

Lars HenriksenandLukas Fleischer 8cbd456640 Fix next recurring appointment
Recurring appointments do not show up in the notification bar as next
appointment. This was partly corrected by 2084f35 (Fix notification of
recurrent appointments, 2017-02-09) and 5aa7a09 (Fix another error in
the notification code, 2017-02-11).

The search function recur_apoint_starts_before() had a wrong second
argument, but is really of no use: the start time of a recurring
appointment is the start time of the very first occurrence (in the
past). A comparison against the item in the notify_app structure tells
nothing of the start time of the current day; at most it eliminates some
future recurring appointments. The function can be dropped, and the
entire recurring appointment list looked through.

The proper start time is found in the main search loop (and called
real_recur_start_time) and must be compared against the item in the
notify_app structure.

But because recur_apoint_find_occurrence() is limited to a particular
day (second argument), two searches are necessary to cover 24 hours.

Unrelated cleanups: removed function return value; changed long to
time_t.

Lars HenriksenandLukas Fleischer 63b03c6b36 Explicit calendar and todo view configuration
The configuration settings for calendar view (monthly/weekly) and todo
view (hide/show completed) used to be saved automatically on calcurse
exit, with values taken from the current interactive settings. They
could not be set explicitly in the configuration menues. Configuration
settings are no longer saved on program exit, but on exit from the
configuration menu. This means that the saved values are those that were
current when the configuration menu was entered. To change a saved
value, you must set the view as desired and then enter/exit the
configuration menu.

The preferred calendar and todo views are no longer automatically taken
from the interactive settings, but are explicitly set in the general
options menu.  Default values are monthly view and hide completed view.

Lars HenriksenandLukas Fleischer b9f23e134a Purge option glorified
The invert filter option is automatically set for -P (and cannot be used
on the command line). The intention is that the grep option (-G) is used
to find the items that should be removed. To remove them, the same
command is run with -P instead of -G.

In general, purge will remove matching items (silently).

Backward compatibility for option -F (no invert filter).

Lars HenriksenandLukas Fleischer 620c4eeca5 CLI: Revert to and update of parse_datetimearg()
An earlier commit ("CLI: take input date format from configuration file,
do not accept time") replaced parse_datetimearg() with parse_datearg()
and eliminated time-of-day from command line date arguments. This made
the full use of filter options impossible.

That earlier commit is reverted and updated. The parse_datearg()
function is replaced by an updated parse_datetimearg() function that

- takes the date format from the configuration file
- accepts date, date-time or time

The updated parse_datetimearg() function has been extended to report
back the type of the date string received in order to set (filter)
options correctly.  Input dates for query ranges (--from, --to, --days)
are still limited to dates only.

Lars HenriksenandLukas Fleischer bcfc71f4fe Safety exit and read-only mode
The key_generic_command() function provides a "safety exit" in case of
online changes that should be dropped at exit when auto_save is on, or
(NEW) should be saved at exit when in read-only mode. A check for
unsaved changes has been added. The command prompt has been extended
with minimal help information.

After commit 05e0fd0 "Quit, autosave and interactive save" you could not
leave calcurse in read-only mode with the quit command because the
key_generic_quit() function interpreted IO_SAVE_CANCEL as a decision (by
the user) to cancel a save-conflict and cancelled the quit as well. Now
the function will quit unconditionally in read-only mode (as stated in
the man page). In normal mode a check for unsaved changes has been added
in case auto-save is off.

Lars HenriksenandLukas Fleischer 7851f46fbb CLI: filter options have no effect for dates before the epoch
With the exception of filter.type_mask, a filter is only applied if set
explicitly on the command line with a filter option. Whether that is the
case, is determined by comparison with the initialization value. For
date related filters (start_from/to, end_from/to) that is -1, hence the
criterion is != -1, not >= 0.

In generel, a filter initialization value should be invalid (i.e. one
that cannot be set explicitly). As times before the epoch (1 January
1970 00:00:00 UTC) are negative, -1 is a valid Unix time. However, as it
cannot be set from the command line, it is probably no problem?

Lars HenriksenandLukas Fleischer 4ba2cc46d7 CLI: time assignments for filter options
Explanation. There is an important difference between "to <date>" (e.g.
to 15/11/2018)  and "to <date time>" (e.g. to "15/11/2018 13:30"):
<date> is a time span (of 24 hours), while <date time> is a point in
time.

"To <date>" really means "to the end of <date>", while "before <date>"
means "before the beginning of <date>". There are 24 hours between the
two, whereas there is only one second between "before <date time>" and
"to <date time>".  Similar for from/after.

An earlier commit introduced parse_datearg() that only accepts a date
without a time. Hence, a date should be treated as a time span from
midnight to one second before next midnight.

The commit also fixes an error detection bug (filter.start_from/to and
filter.end_from/to were updated too early).

Lars HenriksenandLukas Fleischer 3d7bb89c88 CLI: take input date format from configuration file, do not accept time
Before this patch the input date parsing accepts three formats:
yyyy/mm/dd, mm/dd/yyyy, yyyy-mm-dd. They are tried in sequence. It also
accepts an additional time (hh:mm), or a time without a date.

There are several issues with this:

- it is not documented
- the date format dd/mm/yyyy is not accepted
- print_date() and filter option settings (in parse_args()) can only
  handle midnight times (which are the result of a date without time)
- it is highly uncertain what happens if a time (without a date) is
  given; at least the -d option treats a time without colon (1215 for
  12:15) as a number

It seems that acceptance of time input is a by-product and not needed.
For these reasons the input date parsing has been changed:

- the format is taken from the configuration file (as is the case for
  the output date format)
- only a date, and no time, is accepted

Because the input date format is used during parsing of the command
line, the configuration file must be loaded first, i.e. the options -D
or -C must be parsed before the remaining ones. Loading the
configuration file may result in errors (e.g. caused by changes between
versions). For this reason config_load() has been made more tolerant and
issues warnings instead of exiting.

A followup patch will introduce two options to allow the configuration
file settings to be overridden for input and output date formats.

Lars HenriksenandLukas Fleischer 03880a82bf Fix day range for queries
In "--from a --to z", a is included in the range, z not. This is
non-intuitive and disagrees with the semantics of "to" in filter options
like --filter-start-to, where "to" (and "from") are used inclusively (as
opposed to "before" and "after"). It also has the effect that "--from
today --to tomorrow" has a range of 1 day, "--to z" a range of 0 days
(otherwise not allowed), and "--to today --days -1" is allowed and
displays yesterday!

The implementation has been fixed to agree with "inclusive" semantics.
Options --from and -days with negative range are allowed, while --to and
--days are disallowed also when the range is negative.

Lars HenriksenandLukas Fleischer e6cffdc6bd DST fix: daylength v. DAYINSEC
The number of seconds in a day and daylength in seconds differ when
Daylight Saving Time is in effect on two days of the year. The day when DST
takes effect is 23 hours long, and the day when DST ends is 25 hours long.

In the latter case the date changing thread wóuld enter a loop in the last hour
before midnight (in the former it would set the date an hour too late).
The next midnight is calculated through mktime(), invoked by date2sec().

Wrong daylength prevented appointments from being stored in the day vector and
caused them to be displayed wrongly in the appts panel.

Lars HenriksenandLukas Fleischer 4263a28504 DST fix: adjusting time in appointments
Calcurse saves time and date information on disk as local time in readable text
file format. When loaded from disk or when entered by the user, local time is
converted to Unix time (seconds since 00:00:00, 1 January 1970). When
displayed, and later when saved to disk, the Unix time is converted back to
readable local time. Both conversions depend on DST.

Hence, if midnight for a day with DST in effect (i.e. local time) is converted,
increased with an amount and converted back, the amount has changed if DST is
_not_ in effect for the resulting time. In general, calculations on Unix time
variables should be used with caution because of the DST-dependent conversions.
Instead, the calculations should be performed on local time data with the help
of mktime().

The commit fixes start time for pasted appointments (ordinary and recurrent)
and the 'until'-date of recurrent appointments, pasted as well as new and
edited. The latter problem is slightly different in that the adjustment is a
number of days, as it is for exception dates.

Update of the date in parse_datetime() has been corrected to be similar to
update of the time, although no problem has been identified.

Thus mutex protection has been moved from the level:

to two functions at the higher level:

	io_save_cal(), io_reload_data().

The protection includes pre- and post-hooks.

Moving user information to calcurse.c makes it easier to perform the actual
save/reload operatons in io.c, e.g. it is possible to load instead of
reload after a merge in conflict resolving.

The save/reload operations are of such importance that the user should always be
informed of the result (it's a bit disquieting when there is no reaction to a
save or reload command). Hence, the save/reload status messages are no longer
conditioned by show_dialogs(). No confirmation is asked for, so a message stays
until the status bar is updated by another action.

Care is taken to inform about save/reload actions that result in no change.

Texts are kept concise because of the limited message area. When conflicts are
present, whether saving or reloading, the "continue/merge/cancel" pattern seems
easier to grasp.

A reload action will do nothing if in-memory data as well as data files are

Because saving of configuration data and key bindings are mixed up with saving
of data files, any changes in those will only be saved if data files also have
changed. Hence, configuration data and key bindings are also saved upon exit
from the configuration menu.

Lars HenriksenandLukas Fleischer a94b0ecde0 Fix window update after hook execution
The introduction of hooks raised a problem with window updates. The diagnosis
in commit feb059e8 (Fix segmentation fault on reload with pre-load hook) was
right, the cure was wrong.

The problem is wins_update(), not the listbox contents. The wins_update() call
does not belong in wins_unprepare_external() (or in io_reload_data()), but at a
higher level. It should be called _after_ reload, as indeed it is in
key_generic_reload() when the listbox contents have been updated (todo as well
as appointments). The call was introduced in commit 8ae75f3 without comment.

The todo updates in io_reload_data() also belong in key_generic_reload() where
they were before commit 7f06c252.

When saving data, all panels must be updated in case a hook was executed.

Lars HenriksenandLukas Fleischer 223810cf0e Major overhaul of appointment/event input routines.
When setting start time for a new appointment, a date is disallowed
(in all other cases both time and date are still allowed).

Both date and time are displayed for the user to correct when an
appointment is changed or moved.

Built-in help in the status bar for display of input formats.

Several bug fixes that resulted in data inconsistencies (end time
before start time).

The routines use the enhanced parsing funtions to validate input:

	parse_duration()
	parse_datetime()
ui_day_item_repeat(void)
	parse_date_duration()

Lars HenriksenandLukas Fleischer 5e53708648 Solve deadlock in notification bar
calcurse deadlocks when

1) an upcoming appointment is on display in the notification bar,
2) an external command (like help) is started,
3) the time for the upcoming appointment arrives, and
4) the external command is exited.

The notification bar thread is stopped while the external command is
running. Upon exit from the external command, the n-bar thread is
restarted and calcurse locks.

The cause is the way in which the main notification bar thread is
stopped:

static pthread_t notify_t_main;
void notify_stop_main_thread(void)
{
	if (notify_t_main) {
		pthread_cancel(notify_t_main);
		pthread_join(notify_t_main, NULL);
	}
}

Objects of type pthread_t are opaque and should not be accessed
directly.  Initially notify_t_main is an uninitialised static variable
(0), but later it has a value, which may or may not be the thread id of
the notification main thread.

Note that the thread id after exit of a thread may become the thread id
of a new thread. Thus the variable set when the thread is created, is
invalid after exit of the thread.

Specifically, the first time notify_stop_main_thread() is called (by
notify_start_main_thread() before the thread is created) is harmless
(because notify_t_main is 0). Calling notify_stop_main_thread() later
may be either

OK
    because the main thread is running, or
harmless
    because no thread with id notify_t_main is running: the two
    functions will fail with return value ESRCH (no such process), or
fatal
    because an unrelated thread with this thread id is running: it will
    be cancelled, and the join may or may not succeed depending on
    whether the thread is joinable or detached.

The "unrelated thread" could be the next-appointment thread,
notify_thread_app, launched by notify_check_next_app().

Always calling notify_stop_main_thread() before starting the main thread
becomes fatal when notify_check_next_app() is called shortly before
notify_start_main_thread(). This is the case in the scenario described.
The next-app-thread is then running when notify_stop_main_thread() is
called, and apparently it has the thread id of the old main thread
(confirmed by logging the return values from pthread_cancel() and
pthread_join(); the first succeeds while the second fails with EINVALID
which means that the thread is not joinable). The next-app-thread will
therefore exit without unlocking mutexes.

Ensure that notify_t_main, in case the notify main thread is not
running, has a value that it will never have when it is running. A
possibility is the thread id of the main() calcurse process (returned by
pthread_self()).

Check for this condition in notify_stop_main_thread() and set
notify_t_main when the thread is stopped.

Similar changes have been introduced for the periodic save thread and
the calendar date thread.

Lars HenriksenandLukas Fleischer 7078556f9d Key bindings for UTF-8 encoded characters
Internally characters (keys) have two representations: integers and key
names. Key names are characters strings, usually the name of the
character; e.g., the character A has the representations 65 and "A", and
the tab character the representations 9 and "TAB".

The function keys_int2str() turns the integer representation of a
key/character into the key name.

For display purposes the key names are usually confined to have display
width at most three. Some curses pseudo-keys have longer key names;
e.g., the back-tab character is "KEY_BTAB". A long key name makes a
character difficult to recognize in the status bar menu.

The key name of a multibyte, UTF-8 encoded character is the conventional
Unicode name of the code point; e.g., the character ü has key name
"U+00FC" because ü is the code point 0xFC. Most of these look alike in
the status bar menu.

The patch makes the key name of a multibyte character look like that of
a singlebyte character: the character itself, i.e. the key name of the
character ü is "ü".

The main tool is implementation of a utf8_encode() routine.

The key names used are those returned by the keyname() function of

available in the status menu, four ordinary keys and the most common
escape keys have calcurse abbreviated names: ESC, TAB, RET, SPC and LFT,
HOM, PgU, INS, F1, etc.

All keys known by ncurses can be bound. Thus the check for not

only keys that cannot be bound, are those escape keys not known to

Lars HenriksenandLukas Fleischer eeb7038c13 Do not tie ISO 8601 week numbering to Monday
The week number in the calendar panel is calculated according to
ISO 8601. Hence, Monday is the first day of the week and the
week number changes from Sunday to Monday.

However, calcurse ties the week number not to Monday, but to the
first day of the week as configured for display. Thus, when Sunday
is shown as first day of the week, the week number is correct for
Sunday, but wrong for the rest of the week (one behind).

With this patch the week number always follows the mon-sun week as
required by ISO 8601. A side effect is that when Sunday is displayed
as first day of the week, and Sunday is the selected day, the week
number displayed is invalid for the rest of the week (but changes
to the correct one when the selected day moves forward).

This raises the question whether the week numbering scheme should
follow the "first day of the week" choice and use the American week
numbering scheme instead of ISO 8601 when Sunday is the first day
of the week. But that is for the future.
