* Call setsid() for hook/notification commandsLukas Fleischer2021-04-047-12/+19
| | | | | | | | | We do not want hook or notification commands to interact with the terminal in any way. Create a new session for them. Addresses GitHub issue #326. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Redirect standard descriptors for hook/notify commandsLukas Fleischer2021-04-043-26/+11
| | | | | | | | | | | | | Disconnect stdin, stdout and stderr when running an external hook or notification command. The previous solution of appending "<&- >&- 2>&-" to the shell command line does not work if the command includes pipes. Use shell_exec() in notify_launch_cmd() instead of a custom (and incomplete) reimplementation of that command. Partially addresses GitHub issue #326. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
* Add parameter to redirect stderr to shell_exec()Lukas Fleischer2021-04-046-18/+37
| | | | | | | Add a function parameter to allows redirecting stderr in addition to stdin and stdout. The parameter will be used with a follow-up change. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Do not use readlink(1) in testsLukas Fleischer2021-04-033-2/+5
| | | | | | | | | | | | | Avoid using readlink(1) which is not POSIX-compatible; moreover, `readlink -f` is not available on Mac OS by default. Instead, always convert $CALCURSE to an absolute path (that may or may not be canonical, i.e., be a symlink or contain ../ as component) in test-init.sh by prepending the current working directory if the original path is relative. While not fully equivalent to `readlink -f`, this should be good enough for use in our tests. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* calcurse-caldav: improve config file error handlingLukas Fleischer2021-04-031-91/+100
| | | | | | | | | | | | | | The previous implementation allowed sections and keys other than those used by the script which led to a variety of bug reports due to typos in the configuration. Disallow entries other than those explicitly used and make both section and key names case-sensitive (previously, only section names where case-sensitive). Check that Hostname and Path are set before using them. Addresses GitHub issues #327 and #350. Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>

* Keep a linked list sortedLars Henriksen2021-01-163-59/+148
| | | | | | | | | | | | | | | | | | | | | | | | A general linked list function, llist_reorder(), is introduced that will reorder a list after a list element has changed. Some refactoring to avoid code dupliction. Background The four linked lists of appointment panel items (appointments, recurring appointments, events, recurring events) are kept sorted by inserting elements in order, either when they are first loaded from disk or when new are added. The ordering is by start time (numerical) and description (alphabetical). The user is allowed to change start time as well as description. A change is committed directly to the list item (unlike cut/paste where an item is deleted and then inserted). This may break the order. The order property is used when events are loaded from the evenlist into the day_item vector, see LLIST_FIND_FOREACH_CONT, and when looking for the next upcoming appointment, see apoint_check_next().

* Redesign the item deletion menuLukas Fleischer2020-10-111-58/+66
| | | | | | | | | | | | | | | | | | | Instead of the previous inconsistent and potentially nested menus, the following message is now displayed when deleting an item: Delete (s)elected occurrence, (a)ll occurrences, or only the (n)ote? Options that are not available (e.g. because the item is not recurrent or does not have a note) are omitted. For a non-recurrent item without a note the message becomes Delete (s)elected occurrence? and is skipped if general.confirmdelete is disabled. Implements GitHub feature request #308.

* Revert "Interrupt periodic save when launching process"Lars Henriksen2020-07-261-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 0f3d198 (Interrupt periodic save when launching process, 2017-09-08). Stopping and starting periodic save when external/hook programs are run causes deadlocks. The periodic save thread cannot be stopped/started at will, but should be started once and run uninterrupted as long as calcurse runs. Only if the configuration parameter is changed, must the thread be stopped and possibly restarted. The reasons are - the start routine unconditionally starts a thread. - the mechanism used to detect whether a thread is running or not, is designed to be used by the main calcurse thread only and with only one running thread of each kind (the thread ID of each running thread is kept in a variable; if the thread is not running, the variable has the main thread ID as value). Any load hook will be run at the initial dataload, and the stop/start calls will start a perodic save thread (this is true for the notify thread as well). Later when threads are started, a second periodic save thread is started (for the notify thread, a running thread is stopped before restart). When hooks are run by the periodic save thread, the stop call breaks down, leading to two running save threads (if not the case already) and subsequently to a deadlock when one thread tries to stop the other.

* Run hooks quietlyLars Henriksen2020-07-261-15/+20

* Remove SIGCHLD signal handlerLars Henriksen2020-07-264-19/+17
| | | | | | | | | | | | | | The purpose is to make child_wait() reliable. The handler is meant for the notify main thread, but signal handlers are shared by all threads. In the calcurse main thread and the periodic save thread (hooks) the handler and child_wait() will compete (if the signal handler kicks in first, the waitpid() call in child_wait() will fail with errno ECHILD). All child processes in the main thread, the notify thread, the periodic save thread and the notify demon are explicitly waited for.

* Update import of basic recurrence rulesLars Henriksen2020-06-138-128/+329
| | | | | | | | | | | | | | | | | | | 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. Icalendar quotes in comments have been updated to RFC 5545. Signed-off-by: Lars Henriksen <LarsHenriksen@get2net.dk> Signed-off-by: Lukas Fleischer <lfleischer@calcurse.org>
