2013-04-14Use tabs instead of spaces for indentationLukas Fleischer
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>

2012-05-21Switch to Linux kernel coding styleLukas Fleischer
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.

2011-10-05src/llist.h: Add LLIST_{,TS}_FIND_FOREACH_CONTLukas Fleischer
In contrast to LLIST_{,TS}_FIND_FOREACH, these convenience macros search for the first match and return successors until there is an item that isn't matched by the filter callback. Any items beyond the first cut-off are discarded. Should be used when results are known to be continuous, such as appointments and events belonging to a specific day etc. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
2011-10-05src/llist.c: Add llist_next_filter()Lukas Fleischer
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>
2011-10-05src/llist.c: Add a tail pointerLukas Fleischer
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>
2011-04-22Update copyright notices in source files, documentation and "COPYING".Lukas Fleischer
* Update copyright dates (use 2004-2011 as date range everywhere). * Change copyright holder from "Frederic Culot" to "calcurse Development Team". 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>
