* Improve data load error reportingLars Henriksen2020-04-281-11/+10
| | | | | | | | | | | 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(). The four "scan" functions are changed to return an error message on failure and NULL otherwise (the previous return value was not used). Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Filter option: invertLars Henriksen2019-01-071-23/+23
| | | | | | | | | | | | | New filter option: --filter-invert. When present it inverts (negates) the other filter options combined. This is mostly useful with the -G option (with -Q the output is limited by the query range (day range)). The ouput from "calcurse -G <filter options>" is the (set) complement of "calcurse -G <filter options> --filter-invert". Here <filter options> may be any combination of filter options.

* CLI: filter options have no effect for dates before the epochLars Henriksen2019-01-071-4/+4
| | | | | | | | | | | | | | | | 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? Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* DST fix: daylength v. DAYINSECLars Henriksen2018-11-101-1/+1
| | | | | | | | | | | | | | | 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. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* DST fix: adjusting time in appointmentsLars Henriksen2018-11-101-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Fix support for punctual appointments at 00:00Lukas Fleischer2017-08-281-2/+3
| | | | | | | | | | | | | | When checking whether an appointment belongs to a given day in apoint_inday(), the return value was 0 if the end time of the appointment matched 00:00 on that day (because we do not want to include appointments starting on the day before and lasting until midnight). However, this means that punctual appointments at 00:00 were not included in any day. Fix the apoint_inday() logic to take this into consideration. Fixes GitHub issue #39.

* Use tabs instead of spaces for indentationLukas Fleischer2013-04-141-135/+138
| | | | | | | | | | | This completes our switch to the Linux kernel coding style. Note that we still use deeply nested constructs at some places which need to be fixed up later.

| | | | | | | | | | | | | | | | Bail out when reading dates such as "02/30/2013" from the appointments file. These *could* be converted into valid dates but since we never write invalid dates to that file, these indicate a user error.

| * Replace localtime() with localtime_r()Lukas Fleischer2012-11-221-16/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Since the result of localtime() is stored in a statically allocated structure, data was overwritten when a context switch occurred during (or shortly after) the execution of localtime(), potentially resulting in critical data corruption. BUG#7 and BUG#8 are likely related. This patch converts all usages of localtime() with localtime_r(), which is thread-safe.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of calling type-specific duplication handlers and inserting clones of the original items when pasting, save the generic day item and remove the actual item from the linked list, so that it can be inserted anywhere else later. The cut/paste buffer is moved to the interaction unit, item-specific cut operations are changed to remove the item from the linked list only instead of copying and freeing it. An item is only freed if another item is cut before the current cut/paste buffer is pasted. All paste operations are changed and reinsert the actual item instead of creating a clone.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a first step to clean up several compilation units and separate the front end from back-end operations. All functions that require user interaction are moved to a new compilation unit "interaction.c". Also, following things are adjusted to the new layout: * Make day_item_get_*() and a few other functions public, so that it can be accessed from the new compilation unit. * Use apoint_hilt(), todo_hilt(), etc. instead of directly accessing static variables.

|/ | | | | | | | | Pass the recurrent appointment itself instead of passing a date and an item number.

* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-342/+280
| | | | | | | | | | | | | | Convert our code base to adhere to Linux kernel coding style using Lindent, with the following exceptions: * Use spaces, instead of tabs, for indentation. * Use 2-character indentations (instead of 8 characters).

| | | | | | | | | | | | | | | | Commit 4ff3bb9d introduced a new format for parsing durations, thus allowing a larger string to be retrieved from user input. However, the string used is still declared with the old length, leading to crashes when compiling with stack-smashing protection features (the default on Archlinux). Inputting a duration string of more than 8 characters (such as "+1d11h11m") would crash calcurse with a *** stack smashing detected *** message. Using a larger string from the start fixes the bug.
