* Release screen mutex if thread diesLukas Fleischer2012-11-231-6/+6
| | | | | | | | | | | | | | | | | 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.

* Lock screen when drawing on the calendar/notification panelLukas Fleischer2012-11-231-0/+6
| | | | | | | | | | | | 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>
* Replace localtime() with localtime_r()Lukas Fleischer2012-11-221-4/+4
| | | | | | | | | | | | | | 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.

* Use mvwaddstr() instead of mvwprintw()Baptiste Jonglez2012-05-311-2/+2
| | | | | | | | | | | | | 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.

* Do not localize configuration optionsLukas Fleischer2012-05-231-8/+8
| | | | | | | | | The configuration options shown in the configuration menu are meant to reflect the keys used in the configuration file. The descriptions displayed alongside each option should be sufficient for non-English speakers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| * src/notify.c: Fix printf() misuseLukas Fleischer2012-05-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Make sure we actually copy the notification warning interval to the correct buffer instead of printing it to stdout (using an arbitrary format string). This makes sure the current warning interval is shown when editing the field and also eliminates a potential format string vulnerability. Spotted with "-Wformat-nonliteral".

* | Switch to Linux kernel coding styleLukas Fleischer2012-05-211-455/+379
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Update configuration dialogsLukas Fleischer2012-05-171-8/+8
| | | | | | | | | | | | | | Rename the configuration options shown in the configuration dialogs to match the new naming scheme used in the configuration file. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Declare several parameters/variables constantLukas Fleischer2012-05-081-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | 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>

* | Do not strncpy() strings returned by gettext()Lukas Fleischer2012-03-121-1/+1
| | | | | | | | | | | | | | | | Translated strings returned by gettext() are statically allocated. There's no need to copy them to a buffer, we can use the pointers returned by gettext() instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Remove parentheses from return statementsLukas Fleischer2011-11-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | No reason to use "return (x);" here. Refer to the GNU coding guidelines for details. Created using following semantic patch: @@ expression expr; @@ - return (expr); + return expr; Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Do not cast unused return values to voidLukas Fleischer2011-11-021-22/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Avoid use of printf()/fprintf()Lukas Fleischer2011-11-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use one of the following functions where appropriate: * puts() (whenever we print hard coded strings to stdout) * fputs() (whenever we print hard coded strings to a stream) * putchar() (whenever we print a single character to stdout) * fputc() (whenever we print a single character to a stream) * strncpy() (whenever we copy hard coded strings to a buffer) This removes the overhead introduced by the format string parser and reduces the number of false positive C-format strings spotted by xgettext(1)'s heuristics.

* | Avoid unnecessary start time calculationsLukas Fleischer2011-10-211-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Rename recur_*_inday() to recur_*_find_occurrence() and use the new functions whenever we actually care about the start time of an occurrence. Reintroduce recur_*_inday() as wrappers to recur_*_find_occurrence() and pass NULL as start time buffer (which means "skip start time calculation"). Keep using these when we only want to know if a recurrent item belongs to a specific day but do not care about the actual start time. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Pass item durations to recur_item_inday()Lukas Fleischer2011-10-211-4/+4
| | | | | | | | | | | | | | | | Having item's durations eventually allows for better parsing of recurrent appointments as we might be interested in how many days are covered by a multi-day appointment. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add configuration option to notify all appointmentsLukas Fleischer2011-07-311-5/+21
|/ | | | | | | | If "notify-all" is enabled, all non-flagged appointments will be notified (instead of flagged ones). This is useful for users that want to be notified of everything. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix notify_check_repeated()Lukas Fleischer2011-07-291-1/+1
| | | | | | | | | | Remove the "current_time" check from the first if condition. As "greater than" relations (">") have higher precedence than assignments ("=") in C, this caused "real_app_time" to always be one or zero which definitely isn't what we want here. Reading further down, it turns out that we don't even need this comparison here, so we should be fine removing it. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add "force" parameter to notify_check_next_app()Lukas Fleischer2011-07-291-6/+8
| | | | | | | | This allows to force notify_check_next_app() to update the notification appointment, even if start times are equal (e.g. if the item description was changed). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Avoid redundant redraws on resizeLukas Fleischer2011-06-281-14/+19
| | | | | | | | | | Use a global flag to record whether the terminal was resized instead of redrawing everything each time a KEY_RESIZE is read. Add some additional checks to help_write_pad() as invalid actions may be passed now due to using signals instead of virtual key presses. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Use generic lists for recurring item exceptions.Lukas Fleischer2011-04-221-2/+2
| | | | | | | | | Rename "days" structure to "excp" which seems to be a better name here. Use generic linked lists of excp structures instead of using the "days" structure which again contains a linked list implementation. Do some cleanups and invocation fixes.
