that a given set of (working) POSIX functions are available (without
prefixes to their names, etc). See lib/replace/README for a list.
Functions that behave different from their POSIX specification
(such as sys_select, sys_read, etc) have kept the sys_ prefix.

parallel with any transaction

allowing searches to proceed while another process is in a
transaction, then only upgrading the transaction lock to a write lock
on commit.
The solution is:
- split tdb_traverse() into two calls, called tdb_traverse() and
tdb_traverse_read(). The _read() version only gets read locks, and
will fail any write operations made in the callback from the
traverse.
- the normal tdb_traverse() call allows for read or write operations
in the callback, but gets the transaction lock, preventing
transastions from starting inside the traverse
In addition we enforce the following rule that you may not start a
transaction within a traverse callback, although you can start a
traverse within a transaction
With these rules in place I believe all the deadlock possibilities are
removed, and we can now allow for searches to happen in parallel with
transactions

"ldb:nosync = yes/no"
(This used to be commit 435cbcf78b70a82c2ec89fab21e4ff8af538f2f1)
|
|
locking code in the ldb_tdb backend, except for a single read lock
during searches to ensure searches don't cross transaction boundaries
The tdb transactions code would map these extra locks to noops anyway
(as locking makes no sense inside a transaction), but the work in
setting up the locking keys still costs something, and it makes the
code needlessly complex

transactions are synchronous or not on the command line.
add LDB_FLG_NOSYNC flag to ldb_connect() so we can make our temporary
ldb databases non-synchronous

samba-technical posting for more details on the transactions design.
This also adds a number of command line arguments to tdbtorture,
making it more flexible, and fixes some lock deadlock conditions in
the tdbtorture code.

I still have issues with Win2k3 SP1, and Samba4 doesn't pass it's own
test for the moment, but I'm working on these issues :-)
This required a change to the credentials API, so that the special
case for NTLM logins using a principal was indeed handled as a
special, not general case.
Also don't set the realm from a ccache, as then it overrides --option=realm=.

at every single build. Run 'scons configure=1' or delete sconf.cache
to force checks to be re-run.
Jelmer, I think this stuff is cached in the .sconf_cache directory but
the message is still displayed and it looks like it caches the compiled
test object file not the actual result of the test.

-Udomain\\user.
This will probably break in a few configurations, so please let me
know. I'll also work to have a way to inhibit kerberos/ntlmssp, as
this removes -k.

changed the prioivate modules API
error string are now not spread over all
modules but are kept in a single place.
This allows a better control of memory
and error reporting.

private ldb API
ldb_sqlite3 is already working with this model and ldb_tdb will do
as soon as tridge finishes the tdb transaction code.
currently the transactions are always implicit and wrap any single
ldb API call except searching, the transaction functions are
currently not made public on purpose.
Simo.

just involves splitting up the core tdb.c code into separate files on
logical boundaries, but there are some minor functional changes as well:
- move the 'struct tdb_context' into tdb_private.h, hiding it from
users. This was done to allow the structure to change without
breaking code that uses tdb.
- added accessor functions tdb_fd(), tdb_name(), and tdb_log_fn() to
access the elements of struct tdb_context that were used by
external code but are no longer visible
- simplied tdb_append() to use tdb_fetch()/tdb_store(), which is just
as good due to the way tdb locks work
- changed some of the types (such as tdb_off to tdb_off_t) to make
syntax highlighting work better
- removed the old optional spinlock code. It was a bad idea.
- fixed a bug in tdb_reopen_all() that caused tdbtorture to sometimes
fail or report nasty looking errors. This is the only real bug
fixed in this commit. Jeremy/Jerry, you might like to pickup this
change for Samba3, as that could definately affect smbd in
Samba3.
The aim of all of these changes is to make the tdb
transactions/journaling code I am working on easier to write. I
started to write it on top of the existing tdb.c code and it got very
messy. Splitting up the code makes it much easier to follow.
There are more cleanups we could do in tdb, such as using uint32_t
instead of u32 (suggested by metze). I'll leave those for another day.

I must say that writing a new module is a very good way
to find lot of subtle bugs laying in the code
We need more tests!
