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.

do not reference it from ldb.h
|
|
|
|
The only 2 modules escaping the rule so far are rootdse and partitions
|
|
|
|
Some public functions were mistakenly put into ldb_private.h
Revert all modules to only include ldb_module.h
|
|
Separate again the public from the private headers.
Add a new header specific for modules.
Also add service function for modules as now ldb_context and ldb_module are
opaque structures for them.

This introduces a new set of pluggable syntax, for use on the
extended DN, and uses them when parsing the DN.
If the DN appears to be in the extended form, we no longer return the
full DN 'as is', but only return the normal part from
ldb_dn_get_linearized().
When validating/parsing the DN we validate not only the format of the
DN, but also the contents of the GUID or SID (to ensure they are
plausable).
We also have functions to set and get the extended components on the DN.
For now, extended_dn_get_linearized() returns a newly constructed and
allocated string each time.

remove some unused functions.

it should always have been. Make it also async so that it is not a special case.

The previous ldb_search() interface made it way too easy to leak results,
and being able to use a printf-like expression turns to be really useful.

The core ldb code for string matching assumed NULL terminated strings,
whereas the anr module used data_blob_const() to effectively truncate
a ldb_val by changing its length. The ldb code is supposed to be based
around length limited blobs, not NULL terminated strings, so the
correct fix was to change the string comparison functions to be length
limited

This is a partial fix towards bugs due to us walking past the end of
what we think are strings in ldb. There is much more work to do in
this area.
