[Freeipa-devel] [PATCH 0/3] sssd: Rework sysdb to use tevent_req async style

[Simo Sorce]

Hello all,

While working on the native ldap driver I found it increasingly
cumbersome to use the current sysdb transactional code and callbacks.

After some major thinking I decided it would be useful to convert sysdb
to use the tevent_req async style.

This style uses a few conventions that make async programming a lot
easier in my opinion.

What follows are three patches:
1. Prep code renames sysdb_req to sysdb_handle to better reflect what
this structure actually is and avoid confusion with tevent_req
2. Convert all sysdb code to use tevent_req async style
3. Convert the proxy backend

They can be applied one at a time and all should keep working.
I've tested all operations with all 3 applied together and everything
seem working.

I have not yet converted the responder and the sysdb_getXXyyy calls
(except for minor internal adjustments), not sure if it is worth
changing that interface yet.

I may convert the backends interfaae to use directly a tevent_req style
later, but preferred to go in steps. I might propose such a patch
together with the ldap driver.
