ec837150a0 recur_exc_scan(): Do not check time of exceptions
Exceptions do not contain a time field -- do not check time fields which
may be uninitialized.

Regression introduced in 9907069f442c56c90b67accb2d8fbd046dfce6db. This
fixes test/recur-*.sh.

694d28eb78 Use tabs instead of spaces for indentation
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.

9907069f44 Validate date/time when scanning items
Bail out when reading dates such as "02/30/2013" from the appointments
file. These *could* be converted into valid dates but since we never
write invalid dates to that file, these indicate a user error.

Fixes following test cases:

* appointment-009.sh
* appointment-012.sh
* appointment-016.sh
* appointment-019.sh
* event-003.sh

a363cb9b91 Fix braces in if-else statements
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.

e269f09438 Replace localtime() with localtime_r()
Since the result of localtime() is stored in a statically allocated
structure, data was overwritten when a context switch occurred during
(or shortly after) the execution of localtime(), potentially resulting
in critical data corruption. BUG#7 and BUG#8 are likely related.

This patch converts all usages of localtime() with localtime_r(), which
is thread-safe.

6907ae73e7 Revise cut/pasting
Instead of calling type-specific duplication handlers and inserting
clones of the original items when pasting, save the generic day item and
remove the actual item from the linked list, so that it can be inserted
anywhere else later.

The cut/paste buffer is moved to the interaction unit, item-specific cut
operations are changed to remove the item from the linked list only
instead of copying and freeing it. An item is only freed if another item
is cut before the current cut/paste buffer is pasted. All paste
operations are changed and reinsert the actual item instead of creating
a clone.

This is a first step to clean up several compilation units and separate
the front end from back-end operations. All functions that require user
interaction are moved to a new compilation unit "interaction.c". Also,
following things are adjusted to the new layout:

* Make day_item_get_*() and a few other functions public, so that it can
  be accessed from the new compilation unit.

* Use apoint_hilt(), todo_hilt(), etc. instead of directly accessing

b5a911421f Fix incorrect i18n usage for some strings
Some strings are initialized without wrapping them in _(); instead,
_() is applied on the variable when it is used.

This is incorrect, since these strings don't get added to the catalog.

cfd8ede2b3 Switch to Linux kernel coding style
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.

44bc9605d6 Avoid use of printf()/fprintf()
Use one of the following functions where appropriate:

* puts() (whenever we print hard coded strings to stdout)
* fputs() (whenever we print hard coded strings to a stream)
* putchar() (whenever we print a single character to stdout)
* fputc() (whenever we print a single character to a stream)
* strncpy() (whenever we copy hard coded strings to a buffer)

This removes the overhead introduced by the format string parser and
reduces the number of false positive C-format strings spotted by
xgettext(1)'s heuristics.

2bf0249338 Avoid unnecessary start time calculations
Rename recur_*_inday() to recur_*_find_occurrence() and use the new
functions whenever we actually care about the start time of an

Reintroduce recur_*_inday() as wrappers to recur_*_find_occurrence() and
pass NULL as start time buffer (which means "skip start time
calculation"). Keep using these when we only want to know if a recurrent
item belongs to a specific day but do not care about the actual start
time.

Completely rewrite our inday algorithm in recur_item_inday() and be more
fine-grained. This version can deal with recurrent multi-day
appointments unless they overlap.

In case of overlapping appointments, only the last appointment that

whole recur_item_inday() interface in order to fix this - this
relatively trivial patch is only the first step.
