* Add comments to linked list functions.Lukas Fleischer2011-04-221-0/+39

* llist.c: Nullify pointers after free()'ing.Lukas Fleischer2011-04-221-1/+6
| | | | | | | | | | | | | * Set all data members to "NULL" in llist_free_inner() after freeing them. Altough we normally shouldn't continue working with a list that already went through llist_free_inner(), this will protect against dangling pointer bugs in case anyone will ever come up with the idea of doing so. * Set list head to "NULL" in llist_free(), basically to put the list into an initialized state. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use generic lists for recurring item exceptions.Lukas Fleischer2011-04-224-174/+142
| | | | | | | | | 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.

* Remove "next" member from "recur_apoint" structure.Lukas Fleischer2011-04-191-1/+0
| | | | | | | | | | | | Field seems to be unused. Verify using following spatch: ---- @@ struct recur_apoint *rapt; @@ * rapt->next ---- Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use generic lists for recurring apointments and events.Lukas Fleischer2011-04-195-466/+373
| | | | | | | | Use them instead of "recur_apoint_list" and "next" pointers in "recur_event" type variables. Includes some code simplifications and cleanups. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add recur_apoint_inday() and recur_event_inday().Lukas Fleischer2011-04-192-0/+16
| | | | | | | | | | | | To be used with llist_fn_match_t callbacks later. I feel a bit ill adding those functions. This definitely is a hack. Ultimately, there should be some generic recur_item_inday() function that accepts both recurring apointments and events (or some wrapper structure) instead of parameter galeere. This is not the right place to fix that tho. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use generic lists for generic day items.Lukas Fleischer2011-04-192-101/+88
| | | | | | | Use the new generic list implementation instead of "next" pointers in day_item type variables. Includes some cleanups and fixes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Use generic lists for events.Lukas Fleischer2011-04-197-121/+105
| | | | | | | Use the new generic list implementation instead of those insane "next" pointers in events. Includes some cleanups. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Remove "next" member from "apoint" structure.Lukas Fleischer2011-04-191-1/+0

* Use generic lists for appointments.Lukas Fleischer2011-04-195-227/+177
| | | | | | | Use the new generic list implementation instead of "apoint_list" everywhere. Simplify stuff and drop unused variables as well. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add macros to use for thread-safe linked lists.Lukas Fleischer2011-04-192-0/+88
| | | | | | | | | Add LLIST_TS_* macros in a fashion similar to the already existing LLIST_* macros. Unlike the non-thread-safe version, these include LLIST_TS_LOCK and LLIST_TS_UNLOCK which can be used to lock (and unlock) a list (hence the thread-safety). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add macros for linked list operations.Lukas Fleischer2011-04-191-0/+26
| | | | | | | | | | | Mostly in preparation to the pending thread-safe list macros. This way, we have a similar interface to thead-safe and non-thread-safe lists. This also adds LLIST_FOREACH and LLIST_FIND_FOREACH macros which can be used as shortcuts when iterating over all list items or a subset of list items that is accepted by a callback function. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add linked lists implementation.Lukas Fleischer2011-04-194-0/+287
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As discussed on the mailing lists, the various linked list implementations we currently use at a dozen of different places in the calcurse source tree are inconvenient and should be replaced by a single generic solution. This is a first approach to introduce such a generic implemetation. It provides following functions: * llist_init(): Initialize a list. * llist_free_inner(): Loop through a list and free all items. * llist_free(): Free the list itself (but not the individual items). * llist_first(): Get the first item of a list. * llist_nth(): Get the nth item of a list. * llist_next(): Get the successor of a list item. * llist_find_first(): Find an item using a callback function. * llist_find_next(): Find the next match using a callback function. * llist_find_nth(): Find the nth item in a list (using a callback). * llist_get_data(): Get a pointer to the actual data of a list item. * llist_add(): Add an item at the end of a list. * llist_add_sorted(): Add an item to a sorted list (using a comparison callback function). * llist_remove(): Remove an item from a list. Linked lists are stored in "llist_t" structures, list items are to be stored in "llist_item_t" structs. All of the llist_*() functions either expect a pointer to a llist_t structure (in case the function operates on the list itself) or a pointer to a llist_item_t (llist_*_next() and llist_get_data()).

* Use mem_free() instead of xfree() in check_time().Lukas Fleischer2011-04-171-1/+1
| | | | | | | xfree() should never be used directly and only be called by one of the mem_*() wrappers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix io_file_is_empty() behaviour when file starts with a newline.Lukas Fleischer2011-04-121-1/+1
| | | | | | | Read second byte if the first byte is a newline character to ensure the file doesn't contain any further data. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use do-while loops when reading start time and duration in apoint_add().Lukas Fleischer2011-04-121-2/+5
| | | | | | | | Using do-while loops seems more appropriate here as "item_time" hasn't even been read when either of the loops are entered. Spotted by clang-analyzer. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix null pointer dereference in parse_date().Lukas Fleischer2011-04-121-9/+12
| | | | | | | | Passing a date in format "mm-dd-yy" where short forms are not allowed would lead to a null pointer dereference here. This one fixes that. Spotted by clang-analyzer. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Remove some more dead assignments spotted by clang-analyzer.Lukas Fleischer2011-04-122-2/+0

* Declare exit_calcurse() "noreturn".Lukas Fleischer2011-04-121-1/+1
| | | | | | | | Functions that never return should be declared "noreturn" to tell the compiler this fact. Also, clang-analyzer will detect this attribute and take it into account when running scan-build. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Drop empty notes after editing.Lukas Fleischer2011-04-124-0/+32
| | | | | | | | | Keeping empty notes doesn't make sense here. Also, there doesn't seem to be a simple way to erase notes yet. This will make calcurse delete any notes that are empty (meaning that they are either 0-byte files or contain nothing but a newline character) when returning from the editor. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix bad use of unsigned integers.Lukas Fleischer2011-04-052-4/+3
| | | | | | | | Unsigned values should never be compared to values less than zero. Detected with "find_unsigned.cocci" spatch from http://coccinelle.lip6.fr/impact_linux.php. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Parse appointment end times correctly if they date back.Lukas Fleischer2011-03-131-1/+1
| | | | | | | | | End times used to be parsed incorrectly if start and end time's hour components were equal, but the end time was smaller than the start time. This is fixed by comparing the minute components as well in case of equal hour components. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Clean up and simplify line editing functions.Lukas Fleischer2011-03-051-158/+100
| | | | | | | | | This greatly simplifies all line editing functions - especially getstring() and showstring(). showcursor() is removed and integrated into showstring(). del_char() and add_char() are simplified as well. add_char() is renamed to ins_char().

* Ensure key descriptions in status bar are always null-terminated.Lukas Fleischer2011-03-051-0/+1
| | | | | | | | | Key descriptions are just strncpy()'ed to key[], with KEYS_KEYLEN as maximum character count. This leads to a non-null-terminated string if the source pointer actually points to a string with a length of KEYS_KEYLEN bytes. Always appending a null character fixes this.
