55d4d36993 r5102: This is a major simplification of the logic for controlling top level
servers in smbd. The old code still contained a fairly bit of legacy
from the time when smbd was only handling SMB connection. The new code
gets rid of all of the smb_server specific code in smbd/, and creates
a much simpler infrastructures for new server code.

Major changes include:

 - simplified the process model code a lot.

 - got rid of the top level server and service structures
   completely. The top level context is now the event_context. This
   got rid of service.h and server.h completely (they were the most
   confusing parts of the old code)

 - added service_stream.[ch] for the helper functions that are
   specific to stream type services (services that handle streams, and
   use a logically separate process per connection)

 - got rid of the builtin idle_handler code in the service logic, as
   none of the servers were using it, and it can easily be handled by
   a server in future by adding its own timed_event to the event
   context.

 - fixed some major memory leaks in the rpc server code.

 - added registration of servers, rather than hard coding our list of
   possible servers. This allows for servers as modules in the future.

 - temporarily disabled the winbind code until I add the helper
   functions for that type of server

 - added error checking on service startup. If a configured server
   fails to startup then smbd doesn't startup.

 - cleaned up the command line handling in smbd, removing unused options

759da3b915 r5037: got rid of all of the TALLOC_DEPRECATED stuff. My apologies for the
large commit. I thought this was worthwhile to get done for
consistency.

6c14b0133d r4944: every event_add_*() caller was having to call talloc_steal() to take
control of the event, so instead build that into the function. If you
pass NULL as mem_ctx then it leaves it as a child of the events
structure.

fd62df6418 r4943: Smplified the events handling code a lot. The first source of
complexity was that events didn't automatically cleanup
themselves. This was because the events code was written before we had
talloc destructors, so you needed to call event_remove_XX() to clean
the event out of the event lists from every piece of code that used
events. I have now added automatic event destructors, which in turn
allowed me to simplify a lot of the calling code.

The 2nd source of complexity was caused by the ref_count, which was
needed to cope with event handlers destroying events while handling
them, which meant the linked lists became invalid, so the ref_count ws
used to mark events for later destruction.

The new system is much simpler. I now have a ev->destruction_count,
which is incremented in all event destructors. The event dispatch code
checks for changes to this and handles it.

8e16d8a76f r3733: More build system fixes/features:
- Use .mk files directly (no need for a SMB_*_MK() macro when adding a new SUBSYSTEM, MODULE or BINARY). This allows addition of new modules and subsystems without running configure
 - Add support for generating .dot files with the Samba4 dependency tree (as used by the graphviz and springgraph utilities)

dde0705807 r3507: - added deferred replies on sharing violation in pvfs open. The
deferred reply is short-circuited immediately when the file is
  closed by another user, allowing it to be opened by the waiting user.

- added a sane set of timeval manipulation routines

- converted all the events code and code that uses it to use struct
  timeval instead of time_t, which allows for microsecond resolution
  instead of 1 second resolution. This was needed for doing the pvfs
  deferred open code, and is why the patch is so big.

990d76f7cb r3314: added a option "socket:testnonblock" to the generic socket code. If
you set this option (either on the command line using --option or in
smb.conf) then every socket recv or send will return short by random
amounts. This allows you to test that the non-blocking socket logic in
your code works correctly.

I also removed the flags argument to socket_accept(), and instead made
the new socket inherit the flags of the old socket, which makes more
sense to me.

c6888da148 r3304: changed the API to lib/socket/ a little.
The main change is to make socket_recv() take a pre-allocated buffer,
rather than allocating one itself. This allows non-blocking users of
this API to avoid a memcpy(). As a result our messaging code is now
about 10% faster, and the ncacn_ip_tcp and ncalrpc code is also
faster.

The second change was to remove the unused mem_ctx argument from
socket_send(). Having it there implied that memory could be allocated,
which meant the caller had to worry about freeing that memory (if for
example it is sending in a tight loop using the same memory
context). Removing that unused argument keeps life simpler for users.

384f87bd38 r3034: - fixed a bug in message dispatch, when the dispatch function called messaging_deregister()
- added a pvfs_lock_close_pending() hook to remove pending locks on file close

 - fixed the private ptr argument to messaging_deregister() in pvfs_wait

 - fixed a bug in continuing lock requests after a lock that is blocking a pending lock is removed

 - removed bogus brl_unlock() call in lock continue

 - corrected error code for LOCKING_ANDX_CHANGE_LOCKTYPE

 - expanded the lock cancel test suite to test lock cancel by unlock and by close

 - added a testsuite for LOCKING_ANDX_CHANGE_LOCKTYPE

d0cc571e30 r3029: implemented byte range lock timeouts.
This adds a pvfs_wait_message() routine which uses the new messaging
system, event timers and talloc destructors to give a nice generic
async event handling system with a easy to use interface. The
extensions to pvfs_lock.c are based on calls to pvfs_wait_message()
routines.

We now pass all of our smbtorture locking tests, although while
writing this code I have thought of some additonal tests that should
be added, particularly for lock cancel operations. I'll work on that
soon.

This commit also extends the smbtorture lock tests to test the rather
weird 0xEEFFFFFF locking semantics that I have discovered in
win2003. Win2003 treats the 0xEEFFFFFF boundary as special, and will
give different error codes on either side of it. Locks on both sides
are allowed, the only difference is which error code is given when a
lock is denied. Anyone like to hazard a guess as to why? It has
me stumped.

ca7e02fd37 r3026: - added automatic retry to messages when the servers listen queue is
full. This means callers can just "send and forget" rather than
  having to check for a temporary failure. The mechanism takes nice
  advantage of the timed events handling is our events code. A message
  will only fail now if we completely run out of some resource (such
  as memory).

- changed the test code not to do retries itself, but only to warn on real failures
