This patch reduces the time needed to enumerate groups of a midsized
domain from 12 seconds to 4.4
Optimizes enumerations by doing only 2 ldb searches and some ordering
instead of a number of searches proportional to the number of groups

First pass to remove the legacy option and make it just a property of the
provider

This is part of a set of patches to rewrite sysdb to a hopefully better
API, that will also let use use tevent_req async style calls to manipulate
our cache.

This sysdb_req has always really been a transaction handle and not
a request.

Makes LOCAL a normal backend removing some special handling.
Fix/Add id range filtering and name filtering
Filters uid=0 and gid=0 in the proxy backend as 0 is invalid within
sysdb and was causing getxxent calls to fail completely.
Fix nss_ncache_check_xxx calls to avoid dirtying the 'ret' variable and
causing some unwanted failures.
Change sysdb to always return the uid number when searching member entries so
that id range filtering can be perfomed also in group searhes (does not work
with legacy backends)

Turn user entries to Magic Private Groups when groups are quesried.
|
|
Fix infinite loop within initgr functions.
Fix min length check copy&paste error, was filtering valid groups if the name
was short enough and the group had no members.
|
|
|
|
Also unify SYSDB_PW_NAME and SYSDB_GR_NAME in SYSDB_NAME and make it "name"

This function allows a caller to retrieve a list of users who have
logged in on the system, specifying an optional minimum last login
time to trim the list.
I modified sysdb_enumpwent to accept an optional search argument.
GetCachedUsers takes advantage of this argument to limit the search
by the last login time.
I also found and fixed a few additional low-memory conditions
around D-BUS message replies.

Add comments in header files to better explain interfaces and intended usage.
Expose function to convert from ldb errors to errnos.
Add sysdb_attrs helper to add a long integer as a value.
|
|
Provide also helper functions to build struct sysdb_attrs.
Also fix sysdb_get_user_attr() to have a consistent interface
as all other functions.

This patch adds support for requesting user data in the sysdb via
the InfoPipe. It currently has support for reading defined entries
of integral, floating-point or string types.
Tasks remaining:
1) Implement call to the provider when cache is out of date
2) Support byte arrays for userpic and similar
I modified sysdb_search_ctx in sysdb_search.c to accept an array of
attributes to pass into the LDB search.
I also made one additional related fix: the btreemap now sorts in the
correct order. Previously I had accidentally transposed the two
values for sorting, so the map would always have been in exact
reverse order.

This is necessary because in ldb only 1 transaction per context is possible
and all operations (or new transactions) are nested within it.
Will revisit this later when ldb will addresses the problem.
