* Update import of basic recurrence rulesLars Henriksen2020-06-133-122/+208
| | | | | | | | | | | | | | | | | | | Conversion of COUNT to UNTIL was a simple calculation which assumed one repetiton per period (day, week, month or year); it does not take exception days and invalid dates into account. Solved by a new function which returns the n'th occurrence of a recurrence rule. In calcurse UNTIL is interpreted as a day (DATE), in RFC 5545 as a time of day (DATE-TIME). This has implications when a recurrence rule has an occurrence on the UNTIL day, see comment in ical.c An "Import:" note is added when a multi-day event is imported and turned into a calcurse all-day event.

* Fix recurrence rule expansion with ordered weekdayLars Henriksen2020-05-121-20/+43
| | | | | | | | | | | | | | When the order of a weekday in BYDAY rule expansion (like -5SA or 5SU for monthly or 55WE for yearly) exceeds the number of available weekdays in the period (month or year), rule expansion with negative order could result in a floating point exception. The reason: the modified frequency might become zero. Solution. Check order against number of available weekdays and terminate expansion early whenever possible (also for positive orders).

* Take value data type of event start into account in iCal import/exportLars Henriksen2020-05-031-73/+159
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch derives the item type (appointment or event) from the DTSTART value type. It is then used to perform an extended check of date/time values and reject non-conformant import files (like those reported in Github issues #81, (calcurse) events. The patch includes parsing and code corrections and minor refactoring. Background: Ical events are of two types, in calcurse called appointments and events. RFC 5545 has no distinguishing names for them, but describes them in section 3.6.1. The event type is derived from the value type of the DTSTART property. The value type may be either DATE-TIME (appointment) or DATE (event). If not specified by a VALUE property parameter in DTSTART, the default value type is DATE-TIME. The value type must be set explicitly to DATE to get an event. Other properties and rrule parts must agree with the DTSTART value type (DTEND, DURATION, EXDATE and UNTIL). Previously the type of an imported event was derived from the format of the DTSTART value. The DTSTART value type was not taken into account when importing, and not specified for recurring events when exporting (commit 0114289 solved it for events, see GitHub PR #97).

* Treat recurrent events and appointments alikeLars Henriksen2020-04-281-1/+1
| | | | | | | | | | | | | | | | | | | | | The day vector (or "day_items" vector) is used to load the appointments panel with "day_items" (captions, appointments, events). A multi-day appointment has several "day_items" in the day vector. This may also be the case for a recurring item. The day_item structure has a member "start", which for day_items for recurring appointments is set to the occurrence found by recur_item_find_occurrence(), and is used to tell days of a multi-day appointment apart. For day_items for recurring events it was set to "day" of the recur_event structure (the same value for all occurrences) and not used. The value is now the occurrence found by recur_event_find_occurrence(). The patch is backwards compatible and future-proof.

* User interface for recurrence rulesLars Henriksen2020-04-283-77/+416
| | | | | | | | | | | | | | | | | | | | | | | | The function update_rept() is extended with editing of the three recurrence rule lists for BYMONTH, BYMONTHDAY and BYDAY. The integers of the bymonth and bymonthday lists are edited directly as integers, while those of the bywday list are mapped to localized weekday names (as they appear in the calendar panel) with an optional integer prefix (in RFC5545 style: 1MO, -2SA). The RFC5545 (icalendar) requirement that the start day must be the first occurrence and must match the recurrence rule, is met by testing that an occurrence indeed appears on the start day, in these circumstances: - when a recurrent item is loaded from file - when the recurrence rule of an item is edited interactively - when a recurrent appointment gets a new start time - when a recurrent appointment is moved Copy and paste of a recurrent item will only retain the basic recurrence properties of type, frequency, until and exception days.

* Recurrence rule extensionsLars Henriksen2020-04-286-25/+847
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Terms and concepts are from RFC 5545 (the iCalendar specification). Overall design -------------- Calcurse is extended with full support for BYMONTH, BYDAY and BYMONTHDAY recurrence rule (rrule) parts. The three rule parts are lists of, respectively, months, weekdays and monthdays. The lists are added to 'struct rpt' as linked lists of integers, and the data file format is extended accordingly (details below). Load and save of the lists follow the pattern of the existing list of exception dates, also in 'struct rpt'. The function recur_item_find_occurence() is split into a front-end and a back-end. The back-end, called find_occurrence(), is the original function extended with rrule reductions; the front-end retains the original name and performs rrule expansions. Front-end plus back-end are backwards compatible and require no changes in calling functions. There is no user interface in this patch. Data file extensions -------------------- The BYMONTH, BYDAY and BYMONTHDAY lists are added to that part of an item line which describes the recurrence rule (the "{...}" part). Each list is - like the list of exception days - a space-separated string of values identified by the initial character. Each list is optional and, if present, must follow the until date and precede the exception day list. The lists must appear in order BYMONTHDAY list, BYDAY list and BYMONTH list. The possible list values are - BYMONTH: m1, m2, ..., m12 - BYDAY: w0, w1, ..., w6, w7, w-7, w8, w-8, ..., w377, w-377 - BYMONTHDAY: d1, d2, ..., d31, d-1, d-2, ..., d-31 which are interpreted as (cf. RFC 5545) - BYMONTH: January, February, ..., December. - BYDAY: SU, MO, ..., SA, +1SU, -1SU, +1MO, -1MO, ..., +53SA, -53SA - BYMONTHDAY: the first, the second, ..., the 31st, the last, the last but one, ..., the last but 30 day of the month Examples: Thursday, TH, is w4; Saturday, SA, is w6. The seventh Thursday, +7TH, is w53 (7 * 7 + 4 = 53); the last but second Saturday, -2SA, is w-20 (2 * 7 + 6 = 20); the last day of the month is d-1. Note that the values w-1, w-2, ..., w-6 are not used. A recurrent appointment with a BYDAY rule part: 06/23/2019 @ 12:00 -> 06/23/2019 @ 13:00 {1W w0 w6} |every week on Sunday and Saturday An event with a BYDAY and a BYMONTH rule part: 10/27/2019 [1] {1Y w-7 m10} every year on last Sunday in October An event with until date, a BYMONTH rule part and an exception day: 06/23/2019 [1] {1Y -> 08/31/2021 m5 m6 m7 !07/23/2020} every year on the 23rd in May, June and July for three years, starting on Sunday, 23 June 2019, but not on 23 July 2020. Recurrence set expansion and reduction --------------------------------------- In calcurse a recurrence rule is a quadruple (s, d, r, e) consisting of start, duration, repetition pattern and exception days and is implemented as: (time_t start, long dur, struct rpt *rpt, llist_t *exc) In RFC 5545 parlance, a recurrence rule defines a recurrence set consisting of all recurrence instances (occurrences) not earlier than start which match the rule pattern. With this concept in mind, recur_item_find_occurremce() may be thought of as a membership function for a recurrence set. The call recur_item_find_occurrence(s, d, r, e, day, occurrence) returns true if day belongs to the recurrence set of (s, d, r, e); if so occurrence points to the recurrence instance (the set member). For a recurrence rule with only the basic DAYLY, WEEKLY, MONTHLY or YEARLY type and frequency the recurrence set consists of periodically repeated instances. The BYxxx rule parts modify the recurrence set by reducing or expanding it as specified by RFC 5545. Expansion is implemented in the front-end by modifications of start and/or frequency of the rule (s, d, r, e), often several times, in such a way that the desired recurrence instances are included in the recurrence set. This is possible because the front-end as the very first thing checks for early days (day < s). When day is known not to be early, start (s) can safely be moved backwards. Likewise, if frequency must be changed, the front-end checks whether the frequency repetition applies to the week, month or year of day. Reduction is easier and is performed in the back-end along with the existing validity checks. It consists in checking whether month, day of month or weekday of a found occurrence is on the appropriate list.

* Refactor edit of exception daysLars Henriksen2020-04-283-24/+34
| | | | | | | | | | | | | | | The patch contains no functional changes, but is a necessary precondition for extensions of update_rept() (in ui-day.c) with further recurrence rules. The reason is that recurrence parameters must be treated as a whole: if an edit session is cancelled at any point, no value should change, and all parameters should remain as they were. Hence, the new values must only be set after all of them have been determined. This was not the case for the list of exception days, but as long as it was treated last, it did not matter.

* Improve data load error reportingLars Henriksen2020-04-285-53/+54
| | | | | | | | | | | The last part of loading appointments and events is performed by four "scan" functions called from io_load_app(). Failure in this part of data load does not use io_load_error().

* Refactor function calls: recurrence parameters as a single argumentLars Henriksen2020-04-285-189/+151
| | | | | | | | | | | | | | | | | | | | | The recurrence parameters are type, frequency, until date and exception list (in RFC 5545 parlance FREQ, INTERVAL, UNTIL and EXDATE's). When these are passed in a function call, the argument list becomes long and not very readable. When support for extended recurrence rules is implemented, the number of recurrence parameters increases, and function signatures must be amended. Solution: The "struct rpt" is extended with the exception list; any future recurrence parameters are added here. A pointer to this structure replaces the recurrence parameters in function calls. Note: Each recurrent event and appoinment instance has (a pointer to) a "struct rpt" and in addition an exception list. The latter is retained to avoid the derived changes, and the exception list in the structure is initialized to an empty list when the recurrent instance is created.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adresses two issues with the function recur_item_find ocurrence(), one major: mktime(), and one minor: item duration. In addition, some refactoring is done. The following recurrent appointments demonstrate the problems (as described in the message) and are used as test cases in the associated test commit. 03/29/2019 @ 12:00 -> 03/30/2019 @ 11:00 {2D -> 04/03/2019} |two-day - every other day - not on 1/4 03/31/2019 @ 12:00 -> 03/31/2019 @ 13:00 {1D -> 04/01/2019} |daily - not on 31/3, twice on 1/4 03/31/2019 @ 04:00 -> 03/31/2019 @ 05:00 {1W} |weekly - appears after one week 03/31/2019 @ 12:00 -> 03/31/2019 @ 12:00 {1M} |monthly - never appears 03/31/2019 @ 12:00 -> 03/31/2019 @ 12:00 {1Y} |yearly - never appears 10/20/2019 @ 00:00 -> 10/21/2019 @ 01:00 {1W -> 11/03/2019} |25 hours - ends on 27th, but continues on 28th 03/24/2019 @ 00:00 -> 03/25/2019 @ 00:00 {1W -> 04/07/2019} |24 hours - does not continue on April 1 The root cause is two mktime() calls in recur_item_find_occurrence(), both of which use an inherited tm_isdst value in the tm structure. In such cases mktime() will "normalize" the tm stucture if tm_isdst is 0 or 1 and in disagreement with the rest of the tm contents (just like 32 May will be normalized to 1 June). Example. In 2019 DST started on 31/3 at 02:00:00 (in the European Union). If the (local) time "31/3/2018 00:00:00" is passed to mktime() with tm_isdst = 0, the return value is (say) T sec and the tm structure is unchanged, because DST is not in effect at midnight. If the same call is performed with tm_isdst = 1, the return value becomes (T - 3600) sec and the tm structure is normalized to "30/3/2018 23:00:00", tm_isdst = 0. In recur_item_find_occurrence(), the normalized tm structure with wrong day and time is used in ensuing calculations, leading to wrong dates and the errors observed. The first mktime() call is used to calculate the "day span" of the occurrence before the occurrence itself has been determined. But once the occurence is known, the "day span" is easily determined, and there is no need for the first mktime() call. Events have no explicit duration. However, recur_event_find_occurrence() and recur_event_inday() set the duration of an event to DAYINSEC before passing it on to recur_item_find_occurrence(). The value is not correct on the day when DST begins or ends. The interpretation of the daylength should be left to the called function. Hence, duration is set to -1 to signal no (explicit) duration.

* Set time-of-day consistently to midnight for until dayLars Henriksen2019-09-062-8/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A day begins on midnight (inclusive) and ends on midnight (exclusive). A day as a whole is represented by the initial midnight, i.e. time-of-day is 00:00. On load of recurrent appointments (but not events) time-of-day for the until day is set to 23:59. For a newly created recurrent appointment the setting depends on the input method: time-of-day is set to 00:00 if until day is given as a date (day, month and year), but to time-of-day for the start day if given as an offset (+dd). The resulting behaviour is only visible in interactive use of calcurse as proved by the following scenario. 1) Create an appointment with start time 12:00, end time 11:59 (multi day). 2) Turn it into a recurrent appointment of type daily, frequency 3, until day +3. The appointment is correctly displayed with two 2-day occurrences three days apart. 3) Edit the appointment and select Repetition. Accept existing type, frequency and end day (now as a date). The second day of the second occurrence disappears. 4) Repeat 3), but set the end day as an offset (+3). The second day of the second occurrence reappears. The inconsistencies have been eliminated, and time-of-day for the until day is now always 00:00. Also, until day may equal start day, so midnights should be compared.

* Fix monthly and yearly recurrence algorithmsLars Henriksen2019-09-061-5/+6
| | | | | | | | | | | | | | | | | | | | | | | The calculation of the year of the most recent occurrence for year dates before the start date (disregarding the year) is incorrect for frequencies greater than one. The most recent occurrence (for a date as mentioned) is either too far or too close in the past. In most cases it does no harm because the most recent ocurrence is in the past and does not span the date (i.e. there is no occurrence on the day). But the following appointment shows the presence of the bug: 12/31/2019 @ 12:00 -> 01/01/2020 @ 12:00 {2Y} |new year The occurence on 1 Jan 2020 is missing, because the most recent occurrence is too far in the past (31 Dec 2018 instead of 31 Dec 2019). An occurrence appears on 1 Jan 2021, because the most recent occurence is too close in the past (31 Dec 2020 instead of 31 Dec 2019). A similar miscalculation affects the monthly rule as proved by 3/31/2019 @ 12:00 -> 4/1/2019 @ 11:00 {2M} |change of month Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
