This should coalesce identical adjacent notify records - making the "too large"
bug very rare indeed. Please test.

Jeremy, I am always very confused about the different length arguments
in convert_string and friends. Can you take a look at the change in
string_replace and verify it's ok? Thanks!
While at it, remove the pstring limit for strhasupper and strhaslower.

valgrinding will follow.

to all callers of smb_setlen (via set_message()
calls). This will allow the server to reflect back
the correct encryption context.

ntvfs/sysdep/inotify.c -> smbd/notify_inotify.c
Naturally I had to disable notify again :-)

void message_register(int msg_type,
void (*fn)(int msg_type, struct process_id pid,
- void *buf, size_t len))
+ void *buf, size_t len,
+ void *private_data),
+ void *private_data)
{
struct dispatch_fns *dfn;
So this adds a (so far unused) private pointer that is passed from
message_register to the message handler. A prerequisite to implement a tiny
samba4-API compatible wrapper around our messaging system. That itself is
necessary for the Samba4 notify system.
Yes, I know, I could import the whole Samba4 messaging system, but I want to
do it step by step and I think getting notify in is more important in this
step.

yet. Checkin in now, I want to see how the build farm likes it.

based approach. The only remaining hook into the backend is now
void *(*notify_add)(TALLOC_CTX *mem_ctx,
struct event_context *event_ctx,
files_struct *fsp, uint32 *filter);
(Should we put this through the VFS, so that others can more easily plug in?)
The trick here is that the backend can pick filter bits that the main smbd
should not handle anymore. Thanks to tridge for this idea.
The backend can notify the main smbd process via
void notify_fsp(files_struct *fsp, uint32 action, char *name);
The core patch is not big, what makes this more than 1800 lines are the
individual backends that are considerably changed but can be reviewed
one by one.
Based on this I'll continue with inotify now.

sense. Until then, remove it from the tree to keep the diff between 3_0_24 and
3_0 small.

first of the raw-notify subtests, the one-level test_notify_dir without any
flags around yet.
The tricky part was getting the data structures right, I hope the next tests
don't let that fall over.
fsp->notify is now by default NULL, meaning that nobody has issued a
changenotify call. This means nobody is interested in changes for this
directory.
If that has happened, notify_change_buf collects the changes if no current
request is outstanding, and it collects the requests if no change has happened
since the last request.
Happy New Year, somewhere on this planet it's already 2007 :-)

P.S: Jeremy, there's a question for you in smbd/files.c line 367.
(This used to be commit ce0ad24988075465addcac0b9afc872e909135af)
call_nt_transact_notify_change() is now sync if there are changes around.
A notify_message does a direct reply from within the message, so
process_pending_change_notify_queue is not needed anymore for samba-generated
events. Next step is to restructure the kernel-mechanisms to generate
messages.

Checking in because Jeremy was bugging me. Potentially this becomes quite
intrusive, I'm not sure if I should open a temporary branch for this.
Jeremy, Jerry, do you think 3_0 is the right place for this?

send_smb failures should be clean exits. All times when we exit as
a matter of policy should also be clean exits.

when there's no kernel or FAM change notify. If set to zero
this will turn off change notify for the share except when
we ourselves change something (renames / deletes etc. ).
Designed to help on large directory shares where a new
changenotify is issued between each delete. This will
be fixed correctly when we move to internal change notify
(eg. back-port Samba4 changenotify).

I was storing the mid of the oplock break - I should have been
storing the mid from the open. There are thus 2 types of deferred
packet sequence returns - ones that increment the sequence number
(returns from oplock causing opens) and ones that don't (change notify
returns etc). Running with signing forced on does lead to some
interesting tests :-).

in oplock break state, change notify queue) we also push the MID onto
the deferred signing queue. Tomorrow I will test this with valgrind and
oplock tests.
