2011-04-22Return -1 in io_file_is_empty() if file cannot be accessed.Lukas Fleischer
Ensure files don't appear as empty if fopen() fails (e.g. on temporary EACCES failures). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-22Use "event" structure when iterating over events in app_arg().Lukas Fleischer
Regression introduced in commit 5b174ba5d46c256f41c1cfb952d46f49a088db8a. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

2011-04-22llist.c: Nullify pointers after free()'ing.Lukas Fleischer
* 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>
2011-04-22Use generic lists for recurring item exceptions.Lukas Fleischer
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. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Remove "next" member from "recur_apoint" structure.Lukas Fleischer
Field seems to be unused. Verify using following spatch: ---- @@ struct recur_apoint *rapt; @@ * rapt->next ---- Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for recurring apointments and events.Lukas Fleischer
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>
2011-04-19Add recur_apoint_inday() and recur_event_inday().Lukas Fleischer
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>
2011-04-19Use generic lists for generic day items.Lukas Fleischer
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>
2011-04-19Use generic lists for todo items.Lukas Fleischer
Use the new generic list implementation instead of "next" pointers in todo items. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for events.Lukas Fleischer
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>
2011-04-19Remove "next" member from "apoint" structure.Lukas Fleischer
Field seems to be unused. Verify using following spatch: ---- @@ struct apoint *apt; @@ * apt->next ---- Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-19Use generic lists for appointments.Lukas Fleischer
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>
2011-04-19Add macros to use for thread-safe linked lists.Lukas Fleischer
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>
2011-04-19Add macros for linked list operations.Lukas Fleischer
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>
2011-04-19Add linked lists implementation.Lukas Fleischer
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()).

2011-04-17Use mem_free() instead of xfree() in check_time().Lukas Fleischer
xfree() should never be used directly and only be called by one of the mem_*() wrappers. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-12Fix io_file_is_empty() behaviour when file starts with a newline.Lukas Fleischer
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>
2011-04-12Use do-while loops when reading start time and duration in apoint_add().Lukas Fleischer
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>
2011-04-12Fix null pointer dereference in parse_date().Lukas Fleischer
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>
2011-04-12Remove some more dead assignments spotted by clang-analyzer.Lukas Fleischer
Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-04-12Declare exit_calcurse() "noreturn".Lukas Fleischer
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>
2011-04-12Drop empty notes after editing.Lukas Fleischer
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>
2011-04-05Fix bad use of unsigned integers.Lukas Fleischer
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>

Use spaces instead of tabs for source code indentation only, strip trailing whitespaces from lines. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-03-13Parse appointment end times correctly if they date back.Lukas Fleischer
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>

2011-03-05Clean up and simplify line editing functions.Lukas Fleischer
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(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-03-05Ensure key descriptions in status bar are always null-terminated.Lukas Fleischer
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.
