* Use strcmp() instead of strncmp()Lukas Fleischer2012-03-121-2/+2
| | | | | | | | | 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>
* Add a read-only optionLukas Fleischer2012-02-241-9/+4
| | | | | | | We don't save any configuration nor items if this is set. This should be used with care, and hence there's no short option for this. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Fix up strncat() usageLukas Fleischer2012-02-181-2/+2
| | | | | | | | | | | | | | | 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.

* src/config.c: Add missing configuration variablesLukas Fleischer2012-02-171-15/+42
| | | | | | | Append missing configuration variables to the end of our configuration file instead of keeping them undefined. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Revamp configuration file parsingLukas Fleischer2012-02-171-130/+81
| | | | | | | | | | | | | | | | | | | | | Reintroduce a map for configuration variable parsing. We use a different approach this time: Each map entry contains * a key, * a callback that can be used to parse that variable, * a callback that can be used to serialize that variable and * a target buffer that the parsed value is written to/read from. Commits 4f4891bdb88410ae04225f3d6acfa31d73a3901a and 6377582841118688aee13aff98c9216403582e45 show that we are pretty undecided on using a map or not. However, now that we use parser and serialization wrappers for every variable, having a central map makes everything much cleaner. The runtimes of config_load() and config_save() are slightly increased (by a constant factor). This will also allow us for implementing proper detection of missing configuration variables in the configuration file. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Add more parser/serialization wrappersLukas Fleischer2012-02-171-67/+133
| | | | | | | | | | | | Add convenience parser/serialization wrappers for all configuration variables that don't use the default config_parse_*() and config_serialize_*() helpers yet. This is nothing but a dirty hack and should be refactored later (e.g. by separating configuration variable parsing and validation or by adding optional validation functions). It makes it easier to switch to a more generic configuration parser, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Introduce config_parse_str()Lukas Fleischer2012-02-171-13/+14
| | | | | | Be consistent with other parser helpers and with config_serialize_str(). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Keep formatting and commentsLukas Fleischer2012-02-171-131/+46
| | | | | | | | | | | | | Switch to using the new config_file_walk() helper in config_save() and update existing configuration variables instead of blindly overwriting the existing configuration file. Note: This breaks configuration setting storage if one or more settings are missing in the configuration file. We need to refactor our parser and serialization routines another time before this can be implemented properly, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Add serialization helperLukas Fleischer2012-02-171-53/+184
| | | | | | | Add config_serialize_conf() which can be used to serialize the value of a configuration setting (counterpart to config_parse_conf()). Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Add junk callback to config_file_walk()Lukas Fleischer2012-02-161-3/+9
| | | | | | | | | | This can be used if we care about junk, such as empty lines and comments. Currently unused since we skip these when parsing configuration settings. This makes sense if we want to make slight modifications to the configuration file without losing formatting and comments, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Make config file reading more flexibleLukas Fleischer2012-02-161-11/+27
| | | | | | | | | | | | | | This adds one level of abstraction to config_load() by splitting out the actual reading routine and the variable setter into two separate functions. config_file_walk() can be used to read the configuration file, strip comments and pass every key/value pair to a callback. config_load_cb() is the new callback used in config_load(). Rationale: It makes sense to reuse the key/value parser to allow for a much saner config_save() routine that changes single values only instead of rewriting (and overwriting) the whole configuration file every time.

* src/config.c: Drop support for legacy color schemesLukas Fleischer2011-12-121-85/+36
| | | | | | | | | We used different naming schemes in versions prior to 1.8. Given that calcurse 1.8 has been released more than 4.5 years ago, remove the legacy code that still handles these. Users upgrading from <1.8 to 3.0.0 might need to convert the appropriate config file variable manually. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* src/config.c: Remove map for configuration variablesLukas Fleischer2011-12-091-169/+114
| | | | | | | | | | This patch kind of reverts what we did in commit 6377582841118688aee13aff98c9216403582e45. We were a tad off-base there since using a map doesn't improve maintainability, really. Using strcmp() at a central location seems perfectly fine and doesn't have the overhead of the map scanning algorithm. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
* Extract config file handlers into a separate fileLukas Fleischer2011-12-091-0/+583
We used custom_load_conf() to load the configuration file and io_save_conf() to save configuration. Move these functions, including all helpers, to a central location. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
