As the first step to back-end hook support, this patchset makes the ini parser suitable for sharing between alpm and pacman by moving all error handling from the ini parser to the _parse_directive callback. This involves: * moving debug output to the callback * allowing empty section names (alpm already rejects empty db names) * moving Include handling to the callback * notifying the callback of read errors In order to do that I also refactored the config callback to use only a single pass by storing repo information until alpm is initialized and using bitmasks instead of the ALPM_SIG_*_SET enums to handle siglevel inheritance. apg Andrew Gregory (9): conf.c: store repo settings in dedicated struct conf.c: use masks for siglevel inheritance conf.c: parse config in a single pass ini.c: remove final callback call ini.c: move Include parsing to conf.c ini.c: remove unnecessary helper function ini.c: remove empty section name restriction ini.c: remove useless key check ini.c: move error output into conf.c lib/libalpm/alpm.h | 3 - lib/libalpm/be_sync.c | 2 +- src/pacman/conf.c | 304 ++++++++++++++++++++++++++++---------------------- src/pacman/conf.h | 16 +++ src/pacman/ini.c | 147 ++++-------------------- 5 files changed, 208 insertions(+), 264 deletions(-) -- 1.9.2

The return value of calloc needs to be checked to be non NULL. Sören

It looks like this is supposed to lines like: [ ] in the config file. Should the test be key == '\0'?
