- now all write operations appear to work correctly with PostgeSQL 7.0
- all write operations have been made transactional (atomic writes to
entries are committed separately only in case of complete^1 success
while all other operations are rolled-back by default)
- more cleanup and handling of exceptional conditions
TODO:
- deen to check with different databases and more up to date versions
of both unixODBC and PostgreSQL.
^1: attribute add/modify/delete operations silently succeed if the
appropriate add/delete proc does not exist for each attribute;
this may be correct to hide undesired/unimplemented correspondence
between LDAP and SQL databases; however, a more appropriate
LDAP behavior would be a failure with LDAP_UNAVAILABLE if a
single write operation cannot be executed for such reason
- re-style according to the style giudelines for better readability
- updated to recent frontend/backend API changes
- fixed a few quirks about normalization
- "optimized" a few memory allocation/string handling functions
- fixed a few quirks about add/modify (still have to look ad modrdn)
todo:
- there is still something broken (at least with PostgreSQL and IBM db2,
the two RDBMS O have at hand) when adding
- move everything to struct bervals and try to save a few strlen
- try some LDAP/SQL syntax relation to use appropriate value bind if possible
- ...
including:
- fixes according to new API changes
- closing db connection in connection_destroy callback, not unbind
- support of new schema code, samples changed accordingly
- support for multiple objectclasses (to distinguish from unique objectclass-to-tables mapping)
- auto 'ref' attribute support
- samples now include illustrations of using these 2 features to make named referrals as described in ldapext-namedref draft
more to come:
- documentation update
- different improvements to be more close to native directory (after beta?)
- filter -> SQL translation bugfixes
- several memory leaks fixups
- improved configurability:
- allows definition of uppercasing function to support CIS matching on databases that do
case sensitive compares (this fixes up Oracle issues, example updated)
- allows more flexibility in stored procedures interface (different parameter order, optional return
codes - see samples, and comments in backsql.h)
- synchronize function interfaces to recent changes in prototypes ("const" clauses etc.) made for all backends
(those changes led to compile-time errors)
