We have a big mess in debug_level and we log irelevant/confusing messages with hight debug level. Maybe I still miss the point but how this debug_level improves it. And remeber that nothing is *undocumented* in open-source. We(developers) are used to recomend full debul level for debugging issues. So it would very soon to become a standart to require debug_level 0xffff0. And if you coombine it with debug logs from AD with enabled logging from nsupdate it will be a real mess. >> >> These wrappers should not be used in sssd upstream. >> They can be prepared for debugging purposes in development process. > >...which means we will have to rebase the patches, build the correct >version, pass it on to the person and care about correct versioning... > Why should we rebase patches? It rarely happen that we provides custom builds with extra debugging. And everythime it is a different custom build for different user. And it would be the same case with using custom builds with using wrappers. >Sorry, I just don't agree with any of the arguments, but I'm curious >to hear more. Let me explain why wrappers are not good idea in production. There was introduced new wrapper(#1991) for ldb_search SSS_LDB_SEARCH. It should guarantee that ENONET will be returned and not EOK + res->count == 0. I found just a single usage of this wrapper since introducing but many usage of ldb_search (I stopped counting after 10). And there will be the same problem with newly introduced wrappers. It's crystal clear that review does not help. Otherwise we would use SSS_LDB_SEARCH everywhere. That is a reason why I am fine with using wrappers just for a for development but not for productions. Or try to propose some automatic way how to simply log ldifs for *ALL* required ldb functions. IMHO, it would be the best to implement it in libldb itself.
