We need to keep TDB_ALLOW_NESTING as default behavior,
so that existing code continues to work.
However we may change the default together with a major version
number change in future.

Make the default be that transaction is not allowed and any attempt to create a nested transaction will fail with TDB_ERR_NESTING.
If an application can cope with transaction nesting and the implicit
semantics of tdb_transaction_commit(), it can enable transaction nesting
by using the TDB_ALLOW_NESTING flag.

whoever pushed 15d93a5d8e21893e1cca5c989dbf97010aae1622, please check
that what you push compiles and passes tests. In this case it didn't
compile.

j is actually the index of the last element in the list
size of the list though is j+1 <- to make room for the
terminating NULL element
|
|
Difference with previous test for str_list_unique() is
that this test allows number of elements and number
of duplicates to be supplied on command line using
--option="list_unique:count=47"
--option="list_unique:dups=7"

Rather than have a repeat of the bugs we found at the plugfest where
hexidecimal strings must be in upper or lower case in particular
places, ensure that each caller chooses which case they want.
This reverts most of the callers back to upper case, as things were
before tridge's patch. The critical call in the extended DN code is
of course handled in lower case.

This is intended to replace our rfc1738_unescape(), and give us an
rfc1738_escape implementation (and hopefully is better tested and more
secure).

While studying tdb, I've noticed a couple of mismatches between readme
and actual code:
- tdb_open_ex changed it's log_fn argument to log_ctx
- there is now no tdb_update(), which it seems was transformed into
non-exported tdb_update_hash()
There were other mismatches, but I don't remember them now, sorry.

The reason I do it is that when using older python-tdb as shipped in
Debian Lenny, python interpreter crashes on this test:

master's pytdb does not (we have a check for self->closed in obj_close()),
but still...

So that erroneous double tdb_close() calls do not try to close() same
fd again. This is like SAFE_FREE() but for fd.

We no longer use swig for pytdb, so there is no need for swig make
rules. Also pytdb.c header should be updated.

Also, set logging function so we get more informative messages.

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.

There was a race condition that caused the torture.tdb to be left in a
state that needed recovery. The torture code thought that any message
from the tdb code was an error, so the "recovered" message, which is a
TDB_DEBUG_TRACE message, marked the run as being an error when it
isn't.

'place' was going negative, and giving undefined results. The result
was duplicate names which gave errors in SMB2-DIR on PPC and other
systems.

Make always sure the exports and signature files are up to date before
shipping a release.
|
|
|
|
Make sure we always have a sorted (per file) export file.
This way we can directly compare the real export and the check file w/o having
to further sort things.
Also return error code from abi_checks.sh if warnings were reported
|
|
Make sure we do not reference our internal tdb directly.
Let configure define what tdb.h file to use so that builds that use an
extrenal tdb do not include 2 different versions of the tdb header.

Make sure we do not reference our internal talloc directly.
Let configure define what talloc.h file to use so that builds that use an
