* Revert a bunch of strncmp() conversionsLukas Fleischer2012-03-301-22/+22
| | | | | | | | | | | All strncmp() usages were replaced by (evidently) equivalent strcmp() invocations in commit 2c9499bf272e06a62902711c6c20621ef3f80e64. However, some of the strncmp() calls were perfectly justified and we actually broke iCal import and "C-"-style key bindings by converting them to strcmp(). Fix this by reverting all affected conversions. Reported-by: Baptiste Jonglez <baptiste@jonglez.org> Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Update copyright rangesLukas Fleischer2012-03-261-1/+1
| | | | | | Add 2012 to the copyright range for all source and documentation files. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Get rid of string structuresLukas Fleischer2012-03-121-50/+50
| | | | | | | | These were only used to construct constant strings with additional length fields. However, we can just use standard constant character arrays instead and let the compiler calculate the string length. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Use strcmp() instead of strncmp()Lukas Fleischer2012-03-121-22/+22
| | | | | | | | | strncmp() isn't intended to be a secure strcmp() replacement, it is designed to be used if you want to compare the first n characters of two strings. Since we always compare character pointers with string literals, switch to using strcmp() everywhere. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Remove all usages of bzero() and bcopy()Lukas Fleischer2012-02-191-6/+6
| | | | | | | | | The bzero() and bcopy() functions are deprecated and were removed from the POSIX standard in IEEE Std. 1003.1-2008. Remove all usages of bzero()/bcopy() and replace them by appropriate memset()/memmove() calls. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix up strncat() usageLukas Fleischer2012-02-181-2/+1
| | | | | | | | | | | | | | | The last argument to strncat() should not be the total buffer length; it should be the space remaining: The strncat() function shall append not more than n bytes (a null byte and bytes that follow it are not appended) from the array pointed to by s2 to the end of the string pointed to by s1. The initial byte of s2 overwrites the null byte at the end of s1. A terminating null byte is always appended to the result. This patch fixes a couple of potential buffer overflow vulnerabilities.

* Don't chomp on error in ical_readline_init()Lukas Fleischer2012-02-181-4/+6
| | | | | | | Skip the newline check if fgets() returns a NULL string. Fixes another warning seen with "-Wunused-result". Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Split note file generation into separate functionLukas Fleischer2012-01-171-12/+3
| | | | | | | We currently use this in one place only but might reuse this a couple of times later (when migrating to libical). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Break out different import/export formatsLukas Fleischer2012-01-071-0/+1263
Extract iCal and pcal import/export routines into separate files. This reduces complexity of the super huge "io.c" source file and makes it easier to follow changes that affect the iCal and pcal routines only (commits affecting both formats are very uncommon).
