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).

travlocks.lock_rw for lock read/write types, it
was sometimes using it (tdb_next_lock) and
sometimes explicitly using F_WRLCK instead.
Change this to consistently use travlocks.lock_rw
only.
I'm pretty sure about this fix (else I woudn't
be checking this in :-) but tridge and Volker
please review.
Jeremy.
you do a tdb_set_max_dead(tdb, n), then for this tdb a delete operation will
only mark a record as dead and re-use it if a new record is created. The
parameter n allows for at most n dead records per hash chain. If this number
is exceeded, all dead records are put on the central freelist.

mirrors of the hash chain locks to a dynamically allocated one.
Jeremy, I count on you to revert it if the build farm freaks out, it's after
midnight here :-)

emacs compile mode (hint, paste to a file, and compile as "cat
filename").
This allowed me to fix nearly all the warnings for a IA_64 SuSE build
very quickly.
- replacing rename() is pointless - all platforms have it (and the
#define of rename breaks some code)
- use system/locale.h in snprintf.c
- fix passwd.h for initgroups
- stdlib is in replace.h, not needed elsewhere
- fix the initgroups replacement
- fix mapping of dl functions to rep_*
isolation of our portability environment from the main code, and also
simplifies the includes system (no separate #ifdef _SAMBA_BUILD for
tdb. ldb etc now)
First step at fixing the build breakage with the groupmapping test. On Linux,
F_RDLCK is defined to 0, for example NetBSD has it at 1.
Still does not work fully though. Still investigating.

as part of ldb.
This allows tdb failures to be passed all the way up to Samba's DEBUG
system, which allowed easier debugging.
Unfortunately I had to extend the tdb API, as the logging function
didn't have a context pointer.
I've worked over the 'debug levels' in TDB. Most of them were 0,
which didn't seem right, as some were trace-like messages. We didn't
see any of these previously, except when accessing TDB directly.

more agressively coalesce entries in the linked list of the undo
log. The second is to ensure that writes during a transaction into the
hash table don't cause the size of the undo log linked list to grow.
These optimisations don't affect Samba much, but they make a huge
difference to the use of ldb in kde
