* src/llist.h: Add LLIST_{,TS}_FIND_FOREACH_CONTLukas Fleischer2011-10-052-0/+6
| | | | | | | | | | | | 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>
* src/llist.c: Add llist_next_filter()Lukas Fleischer2011-10-053-0/+18
| | | | | | | | | | 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 Fleischer2011-10-053-6/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Add command line argument to run the GC manuallyLukas Fleischer2011-10-051-2/+21
| | | | | | | | Adds a "-g" option that allows for running the garbage collector for note files manually. This is useful for users that do not use note files at all or rarely edit/remove them. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add configuration option to run the GC on exitLukas Fleischer2011-10-055-15/+40
| | | | | | | | If "auto_gc" is enabled, the garbage collector for note files will be run on every exit. As this is an experimental feature and may cause data loss, this is disabled by default. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add a garbage collector for note filesLukas Fleischer2011-10-052-0/+117
| | | | | | | | | | | | Now that we use hashes to identify notes, a garbage collector comes in handy. We search for note files that aren't referenced anywhere. Such files might come up if a note, that isn't connected with any other item, is edited. Huge parts of this code are very hackish due to our data structure layout and the way our hash table implementation works. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Do not unlink() note files on note removalLukas Fleischer2011-10-058-64/+47
| | | | | | | | | | Now that we use hash-based note file names, note files should never be unlinked as a note file might be shared. Also, remove the ERASE_FORCE_KEEP_NOTE flag that no longer makes any sense. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use hash-based file names in ical_read_note()Lukas Fleischer2011-10-051-14/+9

* Use hash-bashed file names in edit_note()Lukas Fleischer2011-10-051-11/+31
| | | | | | | | | | | | | | | | | | Note file names are now generated based on their content. Items using the same note will share a single note file. Please note that this implies a few changes: * Both random-style and hash-style note files need to be handled to ensure we do not break backwards compatibility. * Note files may not be moved or deleted if a note is changed or removed since the original note file might be used by another item as well. * A garbage collector to remove unreferenced note files needs to be implemented. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Accept variable length note namesLukas Fleischer2011-10-054-10/+22
| | | | | | | | Read up to the first blank in note_read() instead of assuming a fixed-width note file name. Accept everything up to 40 characters (which is the length of a SHA1 hash in hexadecimal representation). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

* Add a copy file routineLukas Fleischer2011-10-052-0/+34
| | | | | | | | Add io_file_cp() which can be used to copy an existing source file to another location. We will need this for our new hash-based note file names. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Add a SHA1 implementationLukas Fleischer2011-10-053-0/+300
| | | | | | | | | | | | | | | | | | Add an implementation of the SHA1 hash algorithm based on a public domain project by Steve Reid <sreid@sea-to-sky.net>. You can get the original sources from: ftp://ftp.funet.fi/pub/crypt/hash/sha/sha1.c We will need this for several things. File names of note files will be generated based on a hash their content instead of using a random name. Items can be uniquely identified using a hash. In addition to the regular sha1_init(), sha1_update() and sha1_final() operations, our implementation also contains wrappers for hashing a string or a stream.

| * src/io.c: iCal content line folding correctnessLukas Fleischer2011-08-261-112/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a rather invasive change that introduces correct line folding to our iCal parser. From now on, ical_readline() should be used instead of fgets() to read lines from an iCal file as it unfolds lines automatically. We also need to use shared buffers as each ical_readline() invocation eats up the first part of the next line and stores it in the "lstore" buffer. Subsequent ical_readline() invocations copy the contents of this buffer and append continuation lines. We currently use a single buffer pair that is allocated in io_import_data() and pass it to all subroutines. ical_readline_init() needs to be called once for every buffer pair. It reads the first part of the current line and writes to "lstore", clearing the target buffer at the same time. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* | Add configuration option to notify all appointmentsLukas Fleischer2011-07-314-5/+31
| | | | | | | | | | | | | | | | If "notify-all" is enabled, all non-flagged appointments will be notified (instead of flagged ones). This is useful for users that want to be notified of everything. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| * Fix sort order in app_arg()Lukas Fleischer2011-07-301-52/+78
| | | | | | | | | | | | | | | | | | | | | | | | We used to iterate over the list of regular appointments and the list of recurrent appointments in separate loops, thus leading to recurrent appointments being printed first and regular appointments being printed afterwards, regardless of their start and end times. Merge these loops to coerce precedence of the start time. There's still a fair bit of hackery in here - we will fix that later. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
| * Fix apoint_get() call in apoint_switch_notify()Lukas Fleischer2011-07-291-1/+1
| | | | | | | | | | | | | | We passed the function arguments the wrong way round. This regression was introduced in commit 77ef3fe76e4ce4c9a990e8a5904ad2d83420ca02. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
| * Fix notify_check_repeated()Lukas Fleischer2011-07-291-1/+1
| | | | | | | | | | | | | | | | | | | | Remove the "current_time" check from the first if condition. As "greater than" relations (">") have higher precedence than assignments ("=") in C, this caused "real_app_time" to always be one or zero which definitely isn't what we want here. Reading further down, it turns out that we don't even need this comparison here, so we should be fine removing it. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>

| * Invoke vars_init() before importing data with "-i"Lukas Fleischer2011-07-281-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | We forgot to call vars_init() when importing an item using the "-i" command line argument, which led to the pager configuration variable being unset and hence the pager invocation (triggered to show the log in case there are any errors during import) failing.
