Like TYPESAFE_QSORT() but for the ldb_qsort() function
|
|
This changes the meaning of the ->prev pointer in our doubly linked
lists to point at the end of the list from the front of the list. That
allows us to implement DLIST_ADD_END() and related functions in O(1)
time, which can be a huge saving in many places in Samba.
This also means that the 'type' argument to various DLIST_*() macros
is no longer needed, but I have left it in for now to keep the
patchset small, which will make it easier to revert if any problems
are found. In the future we should remove the 'type' arguments.
(jra. Move the one use of DLIST_TAIL over to the new macros).
|
|
uses of (list)->prev are moved over to DLIST_PREV. This will be replaced
when the final (new) version of the dlinklist.h header is added.

This control will allow inspection of internal ldb values, which would
normally be stripped before being presented to users. The first use
will be stripping linked attribute meta data extended components.
|

(as objectClass will always be a case insensitive ascii string, we can
make a much simpler match function here than for the general case).

ldap_backend used to filter out ldap controls on modify. Also, modified
python binding for ldap_modify to allow writing tests for such controls.

a helper function to a DN element to an ldb_msg using ldb_msg_add_string.

This will help simplify boilerplate comparison functions where we
don't have a shortcut way to compare.

This will be used to allow cancelling of transactions in a child after
a fork()

This I hope will be useful for removing controls from the ldb_reply

Also enhance some other comments.

This allows this control to be specified as critical. We support the
control because we choose to always be durable in our transactions.
We really, really need a 'duplicate request' API, as at the
moment we can't do this without a large, error-prone set of code that
cannot cope with new request fields or types.

AD has the concept of a DN prefixed with B:NN:XXXXXX: that contains a
binary blob. We need to support those in order to give correctly
formatted binary blobs for things like wellKnownObjects
This implementation is not ideal, as it allows for binary blobs on all
DNs, whereas it should only allow them on those with a syntax of
2.5.5.7. We should clean this up in the future, but meanwhile this
implementation at least gets us a working DC join of w2k8 to s4.
This patch also uses a static function for marking DNs as invalid,
which is very useful when debugging this code, as you can break on it
in gdb.

This adds ldb_debug_add() and ldb_debug_end() to format multiline
messages

This is currently only triggered via Samba4's schema code.

When LDB_FLG_ENABLE_TRACING is set ldb will send full traces
of all operations and results

It is useful to be able to control the 2 phase commit from application
code (s4 replication uses it)
|
|
This module is now part of Samba 4's dsdb subsystem rather than
standalone ldb.
|
|
|
|
This add --show-binary to ldbsearch. When this flag is set, binary
blobs will be shown as-is, instead of base64 encoded. This is useful
for some XML encoded attributes, and will also be used as part of some
NDR print formatting for attributes like repsTo.

When a top level method in a module returns an error, it is supposed
to call ldb_module_done(). We ran across a case where this wasn't
done, and then found that in fact that are hundreds of similar cases
in our modules. It took Andrew and I a full day to work out that this
was the cause of a subtle segv in another part of the code.
To try to prevent this happening again, this patch changes
ldb_next_request() to catch the error by checking if a module
returning an error has called ldb_module_done(). If it hasn't then the
call is made on behalf of the module.

The reason we need this is to make multi-tdb transactions safe, with
the partition module. The linked_attributes and repl_meta_data modules
now do extra processing when the transaction ends, and that processing
can fail. When it fails we need to cancel the transaction, which we
can only do if the hook is on the prepare commit instead of the end
transaction call. Otherwise the partition module cannot ensure that no
commit has been done on another partition.

This function provides a easy function for displaying a ldb_message
structure in a human readable format. It is especially useful for
calling in gdb.

This allows us to turn a python LdbMessage back into a string.

It seems quite reasonable to allow modules to re-initialise the set of
cached DNs on the ldb context.

When a attribute is marked as LDB_ATTR_FLAG_UNIQUE_INDEX then attempts
to add a 2nd record that has the same attribute value for this
attribute as another record will fail.
This provides a much more efficient mechanism for ensuring that
attributes like objectGUID are unique
|
|
This is all working towards supporting the full WSPP schema without a
major performance penalty.
We now use binary searches when looking up classes and attributes. We
also avoid the loop loading the attributes into ldb, by adding a hook
to override the ldb attribute search function in a module. The
attributes can thus be loaded once, and then saved as part of the
global schema.
Also added support for a few more key attribute syntaxes, as needed
for the full schema.

This op will be used by the partition module to give us good
transaction semantics across the 4 partitions that sam.ldb uses.
