* Use tabs instead of spaces for indentationLukas Fleischer2013-04-141-135/+136
| | | | | | | | | | | This completes our switch to the Linux kernel coding style. Note that we still use deeply nested constructs at some places which need to be fixed up later. Converted using the `Lindent` script from the Linux kernel code base, along with some manual fixes. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix braces in if-else statementsLukas Fleischer2013-02-171-6/+6
| | | | | | | | | | From the Linux kernel coding guidelines: Do not unnecessarily use braces where a single statement will do. [...] This does not apply if one branch of a conditional statement is a single statement. Use braces in both branches. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* src/llist.c: Compare data pointers if callback is NULLLukas Fleischer2012-06-301-9/+30
| | | | | | | | If a NULL callback is passed to llist_find_*(), fall back to comparing data pointers. The check for a NULL callback pointer is done outside the main loop with an eye towards performance. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Allow passing more complex data to list callbacksLukas Fleischer2012-06-301-4/+4
| | | | | | | | Change the data type of the "data" parameter from "long" to "void *" in llist_find_*() signatures to allow for passing more complex objects. Change all llist_find_*() invocations and callbacks accordingly. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Switch to Linux kernel coding styleLukas Fleischer2012-05-211-114/+86
| | | | | | | | | | | | | | 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.

* src/llist.c: Bail out early on negative indexesLukas Fleischer2012-02-161-1/+7
| | | | | | | Make sure we don't return bogus list elements if negative indexes are used in llist_{,find_}nth(). Bail out early and return NULL instead. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/llist.c: Add llist_next_filter()Lukas Fleischer2011-10-051-0/+13
| | | | | | | | | | This convenience function can be used to return the successor of a list item if it is matched by a filter callback and return NULL otherwise. We will use this for an improved version of the LLIST_FIND_FOREACH macro that can be used whenever results are known to be continuous. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/llist.c: Add a tail pointerLukas Fleischer2011-10-051-6/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding a tail pointer to each list increases memory footprint by four bytes, while reducing the runtime of llist_add() from O(n) to O(1). In testing, the time required to append 100000 elements to a linked list was reduced from 29.245s to 0.009s. Our second main concern is to reduce the runtime of llist_add_sorted() when inserting elements from a presorted list (this is reduced from O(n) to O(1) as well), since the data files contain appointments in sorted order and are always processed front to back. Some local numbers show how this speeds up calcurse startup (test set with 50000 appointments): 0.22user 0.12system 0:00.35elapsed 99%CPU (0avgtext+0avgdata 5396maxresident)k 0inputs+8outputs (0major+1398minor)pagefaults 0swaps As opposed to the unpatched binary: 21.97user 0.25system 0:22.23elapsed 99%CPU (0avgtext+0avgdata 5388maxresident)k 0inputs+48outputs (0major+1396minor)pagefaults 0swaps This is a ~10000% increase in speed. Timings for reading random input files generated by a script stay the same (32.391s vs. 31.776s). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* 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>
* Add linked lists implementation.Lukas Fleischer2011-04-191-0/+212
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()).
