2012-12-16Add hidden key handler windowLukas Fleischer
After BUG#6 had apparently been closed with the screen locks introduced in commit a80f8dcf2c6eb3b54658218bc081ee9694204dd5, some people still had problems with random characters appearing in the notification bar. This was obviously caused by wgetch() refreshing the screen if the status panel was changed. From wgetch(3): If the window is not a pad, and it has been moved or modified since the last call to wrefresh, wrefresh will be called before another character is read. Since the wgetch(3) isn't thread-safe, there were race conditions between the notification bar thread drawing to the notification bar and wgetch() updating the screen. Introduce a (hidden) window that handles all key presses and never gets changed in order to avoid this. Also, call wins_wrefresh() explicitly in status_mesg(), since we can no longer rely on wgetch() updating windows automatically. Fixes reopened BUG#6. Note that this is a hotfix -- FR#26 has been opened to ensure we fix this properly in the next major release. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-25Add compact panels supportLukas Fleischer
Add a configuration option that allows for switching to compact panel mode. In this mode, all window labels are hidden, so that there's more space for actual information. This patch doesn't add a configuration menu entry and doesn't add any documentation. Implements FR#7. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2012-11-23Release screen mutex if thread diesLukas Fleischer
We did not setup a thread cleanup procedure which resulted in calcurse freezing if a thread tried to draw on the screen after another thread was canceled while locking the screen. Note that this kind of cleanup handlers should be added to other mutexes as well. This patch just removes the most common case of triggering a deadlock. Also note that we cannot move pthread_cleanup_push() and pthread_cleanup_pop() into the locking/unlocking functions since both pthread_cleanup_push() and pthread_cleanup_pop() may be implemented as macros that must be used in pairs within the same lexical scope.

2012-11-23Lock screen when drawing on the calendar/notification panelLukas Fleischer
Lock the screen if either the calendar panel or the notification bar is updated to avoid race conditions. Addresses BUG#6. Note that we currently always use a screen-level lock, even if only one window is affected. This is to be changed in the future. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-11-22Replace localtime() with localtime_r()Lukas Fleischer
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.

2012-06-30Implement a cache for the monthly viewLukas Fleischer
Add a very simple cache, which is used to store the days that contain an event or an appointment. This makes redrawing and browsing the calendar panel much faster. The cache has a size of 31 integers (which is equivalent to 124 bytes on a 32 bit system and 248 bytes on a 64 bit system) and invalidates itself if the current month has changed. If an item is added/changed/removed, the cache needs to be invalidated manually by calling calendar_monthly_view_cache_set_invalid(). Note that this will always invalidate the whole cache, even if only one item at the last day of the month was removed. This is a trade-off between simplicity and efficiency.

2012-06-13Add key bindings to go to the previous/next month/yearLukas Fleischer
In addition to generic key bindings for moving one day (week) forward/backward, define similar bindings for moving a month or a year. Of course, count prefixes are allowed here as well. Also add status bar hints and help texts. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-06-13Rename displacement enumeration elementsLukas Fleischer
* Rename "LEFT" to "DAY_PREV", "RIGHT" to "DAY_NEXT", "UP" to "WEEK_PREV" and "DOWN" to "WEEK_NEXT" to reflect the semantics of these operations. Remove the unneeded "MOVES" element. * Reorder code to improve consistency. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-31Make appearance.calendarview more explicit in config fileBaptiste Jonglez
Instead of using 0 or 1 as a value for `appearance.calendarview`, introduce the more explicit "monthly" and "weekly". Also update `scripts/calcurse-upgrade.sh` to reflect the change. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-31Use mvwaddstr() instead of mvwprintw()Baptiste Jonglez
When we only want to display a string at a specific place of the screen, there's no need to use the more complex mvwprintw(), use mvwaddstr() instead. This should be slightly more efficient, and, above all, it prevents weird things to happen if our string contains a '%', being interpreted as an unwanted format string.

2012-05-25Fix incorrect i18n usage for some stringsBaptiste Jonglez
Some strings are initialized without wrapping them in _(); instead, _() is applied on the variable when it is used. This is incorrect, since these strings don't get added to the catalog. Fix that by applying _() only once, when the string is declared. Signed-off-by: Baptiste Jonglez <baptiste--git@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-05-21Switch to Linux kernel coding styleLukas Fleischer
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). Rationale: We currently have too much levels of indentation. Using 8-character tabs would make huge code parts unreadable. These need to be cleaned up before we can switch to 8 characters.

2012-05-08Declare several parameters/variables constantLukas Fleischer
Add the "const" keyword to parameters and variables that are never modified. Most of these were spotted by "-Wwrite-strings". We cast the second parameter to execvp() explicitly as it expects a "char *const[]" where it should expect a "const char *const[]" (according to the documentation, this is due to compatibility reasons). This should be changed once we come up with a better solution. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2012-02-19Remove all usages of bzero() and bcopy()Lukas Fleischer
The bzero() and bcopy() functions are deprecated and were removed from the POSIX standard in IEEE Std. 1003.1-2008. Remove all usages of bzero()/bcopy() and replace them by appropriate memset()/memmove() calls. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2012-01-21src/calendar.c: Fix range check in calendar_move()Lukas Fleischer
We added count prefix support to motion commands in commit 59e006e56d9f893506af56a4ca114fe53b537e49 but obviously forgot to check whether the range checks in calendar_move() still work correctly. Refactor out range checks and replace them by a single check that is performed *after* the new date is computed, but before we assign the new value to the actual selected date. This ensures we won't have to bother about these again when changing/adding functionality in/to calendar_move(), while keeping performance (date_change() is pretty cheap and range violations are corner cases anyway).

2011-11-02Do not cast unused return values to voidLukas Fleischer
A small style fix that removes all remaining "(void)" casts. Using these isn't encouraged in GNU coding guidelines and doesn't serve a certain purpose, except for satisfying a few static code analysis tools. We already nuked some of these in previous patches, but this semantic patch should fix what's left: @@ identifier func; @@ - (void)func ( + func ( ...); Long lines were re-formatted manually.
