/*
* The following changes have been addressed:
*
* Enhancements:
* - re-styled code for better readability
* - upgraded backend API to reflect recent changes
* - LDAP schema is checked when loading SQL/LDAP mapping
* - AttributeDescription/ObjectClass pointers used for more efficient
* mapping lookup
* - bervals used where string length is required often
* - atomized write operations by committing at the end of each operation
* and defaulting connection closure to rollback
* - added LDAP access control to write operations
* - fully implemented modrdn (with rdn attrs change, deleteoldrdn,
* access check, parent/children check and more)
* - added parent access control, children control to delete operation
* - added structuralObjectClass operational attribute check and
* value return on search
* - added hasSubordinate operational attribute on demand
* - search limits are appropriately enforced
* - function backsql_strcat() has been made more efficient
* - concat function has been made configurable by means of a pattern
* - added config switches:
* - fail_if_no_mapping write operations fail if there is no mapping
* - has_ldapinfo_dn_ru overrides autodetect
* - concat_pattern a string containing two '?' is used
* (note that "?||?" should be more portable
* than builtin function "CONCAT(?,?)")
* - strcast_func cast of string constants in "SELECT DISTINCT
* statements (needed by PostgreSQL)
* - upper_needs_cast cast the argument of upper when required
* (basically when building dn substring queries)
* - added noop control
* - added values return filter control
* - hasSubordinate can be used in search filters (with limitations)
* - eliminated oc->name; use oc->oc->soc_cname instead
*
* Todo:
* - add security checks for SQL statements that can be injected (?)
* - re-test with previously supported RDBMs
* - replace dn_ru and so with normalized dn (no need for upper() and so
* in dn match)
* - implement a backsql_normalize() function to replace the upper()
* conversion routines
* - note that subtree deletion, subtree renaming and so could be easily
* implemented (rollback and consistency checks are available :)
* - implement "lastmod" and other operational stuff (ldap_entries table ?)
* - check how to allow multiple operations with one statement, to remove
* BACKSQL_REALLOC_STMT from modify.c (a more recent unixODBC lib?)

* original description:
Changes that were made to the SQL backend.
The patches were made against 2.2.18 and can be applied individually,
but would best be applied in the numerical order of the file names.
A synopsis of each patch is given here:
1. Added an option to set SQL query for the "id_query" operation.
2. Added an option to the SQL backend called "use_subtree_shortcut".
When a search is performed, the SQL query includes a WHERE clause
which says the DN must be "LIKE %". The LIKE operation
can be slow in an RDBM. This shortcut option says that if the
searchbase of the LDAP search is the root DN of the SQL backend,
and thus all objects will match the LIKE operator, do not include
the "LIKE %" clause in the SQL query (it is replaced
instead by the always true "1=1" clause to keep the "AND"'s
working correctly). This option is off by default, and should be
turned on only if all objects to be found in the RDBM are under the
same root DN. Multiple backends working within the same RDBM table
space would encounter problems. LDAP searches whose searchbase are
not at the root DN will bypass this shortcut and employ the LIKE
clause.
3. Added a "create_hint" column to ldap_oc_mappings table. Allows
taking the value of an attr named in "create_hint" and passing it to
the create_proc procedure. This is necessary for when an objectClass's
table is partition indexed by some indexing column and thus the value
in that indexing column cannot change after the row is created. The
value for the indexed column is passed into the create_proc, which
uses it to fill in the indexed column as the new row is created.
4. When loading the values of an attribute, the count(*) of the number
of values is fetched first and memory is allocated for the array of
values and normalized values. The old system of loading the values one
by one and running realloc() on the array of values and normalized
values each time was badly fragmenting memory. The array of values and
normalized values would be side by side in memory, and realloc()'ing
them over and over would force them to leapfrog each other through all
of available memory. Attrs with a large number of values could not be
loaded without crashing the slapd daemon.
5. Added code to interpret the value returned by stored procedures
which have expect_return set. Returned value is interpreted as an LDAP
return code. This allows the distinction between the SQL failing to
execute and the SQL running to completion and returning an error code
which can indicate a policy violation.
6. Added RDBM connection pooling. Once an operation is finished the
connection to the RDBM is returned to a pool rather than closing.
Allows the next operation to skip the initialization and authentication
phases of contacting the RDBM. Also, if licensing with ODBC places
a limit on the number of connections, an LDAP thread can block waiting
for another thread to finish, so that no LDAP errors are returned
for having more LDAP connections than allowed RDBM connections. An
RDBM connection which receives an SQL error is marked as "tainted"
so that it will be closed rather than returned to the pool.
Also, RDBM connections must be bound to a given LDAP connection AND
operation number, and NOT just the connection number. Asynchronous
LDAP clients can have multiple simultaneous LDAP operations which
should not share the same RDBM connection. A given LDAP operation can
even make multiple SQL operations (e.g. a BIND operation which
requires SASL to perform an LDAP search to convert the SASL ID to an
LDAP DN), so each RDBM connection now has a refcount that must reach
zero before the connection is returned to the free pool.
7. Added ability to change the objectClass of an object. Required
considerable work to copy all attributes out of old object and into
new object. Does a schema check before proceeding. Creates a new
object, fills it in, deletes the old object, then changes the
oc_map_id and keyval of the entry in the "ldap_entries" table.
8. Generic fixes. Includes initializing pointers before they
get used in error branch cases, pointer checks before dereferencing,
resetting a return code to success after a COMPARE op, sealing
memory leaks, and in search.c, changing some of the "1=1" tests to
"2=2", "3=3", etc so that when reading slapd trace output, the
location in the source code where the x=x test was added to the SQL
can be easily distinguished.
