ctdb wants a quick way to detect corrupt tdbs; particularly, tdbs with
loops in their hash chains. tdb_check() provides this.

This means you can kill it at any time and expect no corruption.

It was a regrettable hack which I used to reduce line count in tdb; in fact it caused confusion as can be seen in this patch.
In particular, ecode now needs to be set before TDB_LOG anyway, and having it exposed in
the header is useless (the struct tdb_context isn't defined, so it's doubly useless).
Also, we should never set errno, as io.c was doing.

When TDB_TRACE is defined (in tdb_private.h), verbose tracing of tdb operations is enabled.
This can be replayed using "replay_trace" from http://ccan.ozlabs.org/info/tdb.
The majority of this patch comes from moving internal functions to _<funcname> to
avoid double-tracing. There should be no additional overhead for the normal (!TDB_TRACE)
case.
Note that the verbose traces compress really well with rzip.

The strlen() could go past the end of a non-null terminated value

This should make upgrades easier

The previous code would fail if the caller used tdb:// in the URL for the
top-level database.

We need to keep the old 'ares' from the remote server around so we can forward
it back to the caller. We can't send the same controls (from the last search
entry) twice (and it makes no sense anyway).
Andrew Bartlett

This helps track the memory better, as we can then place it under the partition
hirarchy.
Andrew Bartlett
|
|
If we don't talloc_free the handle, we leak the memory onto the long-term
context.
Andrew Bartlett
|
|
This ensures that the partition control, needed here for repl_meta_data's
internal work, is not pushed up to other callers.
Andrew Bartlett
|
|
This I hope will be useful for removing controls from the ldb_reply
Andrew Bartlett
|
|
The user entry is only required for this function, so use
mem_ctx to hold it.
Andrew Bartlett
|
|
This is mostly cosmetics, but helped me see that these are legitimate stuctures
when viewed in the talloc tree.
Also don't put the 'ndr' structure on the long-term tree.

This is a collection of fixes to allow the creation of new partitions,
as well as adding debugging that may be useful in chasing down future
failures.
Andrew Bartlett
|
|
This helps us upgrade from sam.ldb files before the dynamic partitions
work, and ensures we use the right casefolding functions.
Andrew Bartlett
|
|
This is no longer required, as the instancetype module is now above
repl_meta_data.
Andrew Bartlett
|
|
The problem here has been avoided in repl_meta_data, and so this is no
longer required.
Andrew Bartlett
|
|
This major rework of repl_meta_data changes it from using a static
list of partitions to a dynamic list created from the controls placed
on returned ldb results.
To process these in one place, the similar but distinct callbacks are
combined into a single replmd_op_callback(), which handles both the
'normal operation' and 'inbound replication' case.
This allows new partitions to be created, and replication events for
these new partitions to be scheduled immediately.
Also in this commit: We no longer specify the target partition for new
or modified objects - instead we allow the partitions module to use
the DN as normal. THis avoids the issue where we would create two
partition head records.
Andrew Bartlett
|
|
|
|
This means we don't return any control for modifications to the
control records in sam.ldb, but do if they modified one of the actual
data LDB files.
Andrew Bartlett
|
|
|
|
This allows one instance of LDB to add a partition, and another to use
it without first closing the database.
Andrew Bartlett
|
|
I see no reason to reload it when in a transaction - it can't change
on us anyway (we possibly need to watch for our own changes to
@PARTITION however)
Andrew Bartlett
|
|
This uses the fact that the primary DB does not change often. Before
each operation, we see if the sequence number has changed.
Andrew Bartlett
|
|
|
|
This allows a blackbox test to confirm this can be set.
Andrew Bartlett
|
|
This helps us ensure we always set the metadata, even when we are
'adding' a partition that is already in our list. (We *really* don't
want these getting out of sync, and the extra writes are harmless)
Andrew Bartlett
|
|
The issue here is that if we don't put the partitions metadata in the
database before we wipe it, we won't wipe the partitions contents, and
so the provision will later fail (entry already exists)
Andrew Bartlett
|
|
The issue here is that before we load the schema partition, we may not
have the correct casefolding rules. As such, keep things simple and
use the DN exactly as found in the @PARTITIONS record to find the
database.
Andrew Bartlett
|
|
|
|
This is needed because the new format of the partitions record is a
casefolded DN, not a DN and file combination.
Andrew Bartlett
|
|
I really don't want a cn=foo/../bar in my ldb file name.
Andrew Bartlett
|
|
This allows the partition to be created before we try and set a
notification on it. (perhaps extra work required here for partition
heads).
Andrew Bartlett
|
|
The new partitions code knows to copy these items in when creating a
new parition, so we can set it from the start.
Andrew Bartlett
|
|
This is done by passing an extended operation to the partitions module
to extend the @PARTITION record and to extend the in-memory list of
partitions.
This also splits things up into module parts that belong above and below
repl_meta_data
Also slit the partitions module into two files due to the complexity
of the code

Currenly implemented functions are:
dsdb_schema_pfm_new(), dsdb_schema_pfm_make_attid()
and dsdb_schema_pfm_oid_from_attid()
|
|
Currenly those tests cover only the main part of the interface,
i.e. dsdb_schema_pfm_new(), dsdb_schema_pfm_make_attid()
and dsdb_schema_pfm_oid_from_attid()

ATTID is marked as partial by adding 32768.
Thus the check should be '>= 32768'
