* Add hidden key handler windowLukas Fleischer2012-12-1610-31/+41
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

* wins_show(): Fix size of the slave window arrayLukas Fleischer2012-12-061-1/+1
| | | | | | | | | | | The slave window array was just big enough to hold a single element, whereas two elements are written/accessed. Fix this off-by-one error in the array declaration. Note that this messed up the panel layout when using clang as a compiler. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* io_load_keys(): Skip legacy entryLukas Fleischer2012-12-051-0/+5
| | | | | | | This binding was used pre-3.1.0. Simply ignore it and avoid showing a needlessly complicated error message. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* keys_save_bindings(): Skip unset key bindingsLukas Fleischer2012-12-051-2/+6
| | | | | | | Saving unset key bindings currently results in a segmentation fault or invalid key specifiers being stored. Skip these entries to avoid this. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| * Ignore signals during command executionLukas Fleischer2012-11-283-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | Disable signal handlers in wins_prepare_external() and reactivate them in wins_unprepare_external(). Before, it was possible that resizing the window during editor/pager mode resulted in the calcurse main screen appearing on top. Addresses BUG#9.

| | | | | | | | | | | | | | This was broken in commit 87fb8cfec0d8e8fc901746095458bd316314b6ee. Fix function signatures and update all invocations accordingly. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Add compact panels supportLukas Fleischer2012-11-257-15/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | Avoid core dump if window is too smallLukas Fleischer2012-11-251-0/+3

* | Add configuration option to set a default panelLukas Fleischer2012-11-254-10/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | This allows for customizing the panel that is selected by default when calcurse is started. Note that this patch doesn't add any documentation. Also, this configuration option currently cannot be configured using the configuration menu. Implements FR#19. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Remove wins_slctd_init()Lukas Fleischer2012-11-253-8/+1

* | io_load_*(): Add line numbers to error messagesLukas Fleischer2012-11-231-12/+26

| * Release screen mutex if thread diesLukas Fleischer2012-11-234-32/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Fleischer2012-11-234-3/+61
| | | | | | | | | | | | | | | | | | | | | | | | 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>
| * Do not display a mark when files are auto-savedLukas Fleischer2012-11-232-23/+2
| | | | | | | | | | | | | | | | | | | | This is kind of useless since users are not able to react to an auto-save notification. It also causes all kinds of problems if the status bar is in a non-standard mode (message, prompt, ...) and is prone to race conditions if the status bar is updated by another thread at the same time.

| * Replace localtime() with localtime_r()Lukas Fleischer2012-11-2210-126/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 status_ask_choice() for the export dialogLukas Fleischer2012-11-183-39/+14

* | Remove unused parameter from key handlersLukas Fleischer2012-11-181-46/+46

* | calcurse.c: Break up key_change_priority()Lukas Fleischer2012-11-181-5/+14

* | calcurse.c: Refactor the main loopLukas Fleischer2012-11-181-353/+425
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Break up the big switch statement into several functions. The functions are declared inline to avoid unnecessary function calls. Also: * Add a "KEY_HANDLER" macro can be used as a short version of a "case" statement, followed by a function call. * Declare several state variables global to avoid having to pass them to each of the new handlers. * Pass the pressed key to each of the handler functions in order not to break handlers that handled more than one key before the handlers were pulled out. These three changes were introduced to keep this patch as atomic as possible and are intended to be removed in following patches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Use integers rather than floats everywhereLukas Fleischer2012-07-104-25/+21
| | | | | | | | | | | | | | | | | | | | | | We don't need floating point precision if results are casted back to integer. Instead, rearrange operations and do the integer division after the multiplication. Version numbers are terminating decimals anyway and can be stored using two integers without losing any information. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* | Add support for copy/paste registersLukas Fleischer2012-07-077-38/+63
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for vim-style copy/paste registers which allows cutting and copying multiple items without having to overwrite the copy/paste buffer. Registers can be specified using the quote key ('"'). To access a register, type '"x' before a command where "x" is the name of a register. If you want to copy the currently selected item into register 1, type '"1c'. Valid registers are 0-9, a-z, "-" and "_". Note that the latter is the so-called black hole register, which works similar to the black hole register in vim. The register prefix key is currently hardcoded and cannot be configured.

* | Implement a cache for the monthly viewLukas Fleischer2012-06-304-1/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
