It may not be needed now, but what if LIBINI_CONFIG_V2 comes out? We
should make sure that the code either compiles where it can or errors
out with a reasonable message.
I also noticed one more thing I'd like to get fixed. "ini_config.h" is
always included, but it's kind of in between the ifdefs. Can you shuffle
the includes to read:
-----------
#ifdef HAVE_LIBINI_CONFIG_V1
#include "ini_configobj.h"
#elif HAVE_LIBINI_CONFIG_V0
#include "collection.h"
#include "collection_tools.h"
#else
#error "Unsupported INI version"
#endif
#include "ini_config.h"
-----------
The #error doesn't have to be used from then on, I think, the
compilation would error out anyway.
The other changes look good to me now. To sum it up:
1) Use either sizeof, #define, or, since we already switched to C99, a
const int instead of hardcoded array length for the timebuf.
2) the ifdef change above
3) sss_confdb_create_ldif() has style issues. They predate your
changes, most probably but we should fix them when we're moving the
code. In particual, there should be a whitespace after a keyword -- use
"if (" not "if(" and "for (" not "for(".
4) sss_ini_check_config_obj() could be made more readable to:
int sss_ini_check_config_obj(struct sss_ini_initdata *init_data)
{
if (init_data->obj == NULL) {
return ENOENT;
}
return EOK;
}
A code shouldn't only return from if-else staments.
I think the patch will be good to go when we fix these last nitpicks.
