The restructured code makes this hader to support, and we have not had
this kind of LDB for a very long time now.

(The format of index records in the internal manipulation changed)

This is currently only triggered via Samba4's schema code.
|
|
When doing an indexed search if we hit a corrupt record we abandoned
the indexed search and did a full search. The problem was that we
might have sent some records to the caller already, which means the
caller ended up with duplicate records. Fix this by returning a search
error if indexing returns an error and we have given any records to
the caller.
|
|
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.
|

|
|
With unique indexes, any rename of a record that has an attribute that
is uniquely indexed needs to be done as a delete followed by an add,
otherwse you'll get an error that the attribute value already exists.
|
|
When a attribute is marked unique we know that if we find a match
it will be the only possible match. This means that in a list of
subtrees connected by an &, it is best to first load the index values
for the unique entries, as if they find something then we know we
won't have to look any further.
This helps with searches like this:
(&(objectclass=user)(samaccountname=tridge))
the old code would first have loaded the very large index for the
objectclass=user attribute, and then loaded the single entry for
samaccountname=tridge. Now we load the samaccountname=tridge entry
first, notice that it gives us a single result, and stop, thereby
skipping the load of the objectclass=user index record completely.
|
|
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
|
|
When looking at performance problems with ldb it can be useful to see
which searches causes unindexed full searches. This makes it easy to
enable that.
|
|
one-level indexing was not always effective due to some broken logic
in the indexing code. This change means that if normal indexing fails,
we can still fall back on one-level indexing.
This reduces the number of full unindexed searches in s4 quite a lot
|
|
|
|
This op will be used by the partition module to give us good
transaction semantics across the 4 partitions that sam.ldb uses.
|
|
Extended operations return was not going thorugh the same patch as others
leaving the ctx around. Plus we were neutralizing the spy too early so that it
didn't set the request_terminated flag as it should have.
This should hopefully fix the failures in the build farm.
|
|
In some code paths ltdb_context was still referenced even after we were returned
an error by one of the callbacks. Because the interface assumes that once an
error is returned the ldb_request may be freed, and because the ltdb_context was
allocated as a child of the request, this might cause access to freed memory.
Allocate the ltdb_context on ldb, and keep track of what's going on with the
request by adding a spy children on it. This way even if the request is freed
before the ltdb_callback is called, we will safely free the ctx and just quietly
return.
|
|
do not reference it from ldb.h
|
|
behavior anyway, and given we can only have one transaction active per
ldb context this is the only sane model we can support.
Fix ldb_tdb transactions, we could return back with an error with neither
committing nor canceling the actual tdb transaction in some error paths
within the ltdb commit and cancel transaction paths.
Added also some debugging to trace what was going on.
|
|
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.

It changes some "return 0" in "return LDB_SUCCESS"
|
|
This also asserts that it is used only for index records.

ldb indexing can cause huge files, and huge memory usage. This
experiment allows us to keep indexes in memory during a transaction,
then to write the indexes to disk when the transaction completes. The
result is that the db is much smaller (we have seen improvements of
about 100x in file size) and memory usage during large transactions is
also greatly reduced
Note that this patch uses the unusual strategy of putting pointers
into a ldb (and thus into a tdb). This works because the pointers are
only there during a transaction, so the pointers are not exposed to
any other users of the database. The pointers allow us to avoid some
really bad allocation problems with tdb record allocation during the
re-indexing.
|
|
re-indexing in ldb is triggered on any modification to the @ATTRIBUTES
or @INDEXLIST records. This happens to produce a worst-case
fragmentation of the database, as all @INDEX records are deleted then
re-created. By repacking after re-indexing we ensure that the database
ends up without extreme fragmentation.

(Even if the callback takes some time, this isn't a ldb_tdb timeout
any more)
