to do so may result in lost data. Fix an ifdef check, I really think we meant to check HAVE_MMAP here.

With the ctdb checkin dde9f3f006 tdb optimized out write lock checks for
write-enabled transaction. Sadly, this also removed the possibility to ever
remove dead records left over from tdb_delete calls within a transaction.
Tridge, please check this! Did dde9f3f006 have any reason beyond performance
optimizations?
Thanks,
Volker

This reverts commit fafb8ad2b81b9a46cf8259bedc1dca5023b06115.
This fix is not valid:
1. convert_string() is not only used for key strings but also for data.
2. Some databases use string_tdb_data() i.e. non-null-terminated strings
as keynames and others (like the one I was using), use
string_term_tdb_data(), i.e. zero-terminated key strings.
After discussion with Metze, the easiest (and proper way) to
handle this is to specify key names as "keyname\0" for databases
which use string_term_tdb_data().
Sorry for the noise...

This prevented all commands operating on keys (all non-traverse commands)
in tdbtool to fail with a "fetch failed" or "delete failed" message.
It seems that it fixes bug #2344 ...
Apparently this bug was introduced with 94e53472666ed in 2005.
Either nobody is using tdbtool or else tdb_find() has become
more strict about the key legth in the meantime. :-)

used for tdb_traverse() to tdb_traverse_read().
Jeremy.

Calling tdb_traverse inside a transaction led to the transaction lock being
held indefinitely. This was caused by the tdb_transaction_lock/unlock inside
tdb_traverse: The transaction code holds the global lock at offset
TRANSACTION_LOCK. The call to tdb_transaction_lock does nothing because the
transaction_lock is already being held. tdb_transaction_unlock inside tdb_wrap
resets tdb->have_transaction_lock but does not release the kernel-level fcntl
lock. transaction_commit later on does not release that fcntl lock either,
because tdb->have_transaction_lock was already reset by tdb_transaction().
This patch does fix that problem for me. An alternative would be to make
tdb->have_transaction_lock a counter that can cope with proper nesting, maybe
in other places as well.

error condition to write. This is in tdb_new_database.
Fix one call to tdb_new_database in tdb_open_ex to not
overwrite the newly propagated errno (typically ENOSPC).

* prevent infinite loops due to 0 bytes written:
try once more. if we still get 0 as return,
set errno to ENOSPC and return -1 (error)
* replace int by correct types (ssize_t and size_t).
* print a warning log message in case "written < requested to write"
usually this means, that the next call to pwrite will fail
with return value -1 and set errno accordingly.
Note that the former error condition "written != requested to write"
is not a correct error condition of write/pwrite. If this is due
to an error, a subsequent call to (p)write will reveal the cause
(typically "no space left on device" - ENOSPC).

The proper error condition is (ret == -1) instead of
(ret != number_of_byte_told_to_write).
