management system I proposed on samba-technical a couple of days
ago. Essentially it is a very lightweight way for any code in Samba to
make IDL based rpc calls to anywhere else in the code, without the
client or server having to go to the trouble of setting up a full rpc
service.
It can be used with any of our existing IDL, but I expect it will
mostly be used for a new set of Samba specific management calls.
The LOCAL-IRPC torture test demonstrates how it can be used by calling
the echo_AddOne() call over this transport.

session data
in the web server
(This used to be commit ac438f0a9cc38ebec95133250c04c4935032b24d)

This includes an embedded server side scripting system called 'esp'
(see http://www.appwebserver.org/products/esp/esp.html) and javascript
based scripting language called 'esj' (see
http://www.appwebserver.org/products/ejs/ejs.html)
The justification for including this scripting language is that it
should make it much easier to write a high quality web interface for
Samba4. The scripting language can call into any Samba4 library code
(so for example it will be able to make ldb and loadparm calls), plus
it provides easy support for forms, cookies, sessions etc.
There is still quite a bit more work to do on the web server, but
there is enough here now for people to look at and comment. I will be
committing some sample web pages that test esp functionality shortly.

2. Also, don't try to delete directories.
I am not entirely happy with this patch, and the fact that there is a
define for HAVE_SYS_STAT_H suggests that there are some systems for which
stat will not be defined, which means that the patch is not entirely
portable.

- if we have no configured network interfaces, then don't start nbtd (when I add dynamic
interface loading this will change to a delay until a network interface comes up)
- choose the best interface by netmask for torture tests that need a
specific IP (such as the WINS test). Added iface_best_ip() for that.
- if specific interfaces are chosen in smb.conf, then keep that ordering, and
default to the first one listed

decide to reinstate the mutex code for the threads process model, I'd

less likely that anyone will use pstring for new code
- got rid of winbind_client.h from includes.h. This one triggered a
huge change, as winbind_client.h was including system/filesys.h and
defining the old uint32 and uint16 types, as well as its own
pstring and fstring.

- removed the u32 hack in events.c as I think this was only needed as
tdb.h defines u32. Metze, can you check that this hack is indeed no
longer needed on your suse system?

make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.
I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)

the packets it receives, but it at least shows how the server
structure will work.
To implement it I extended the libcli/nbt/ library to allow for an
incoming packet handler to be registered. That allows the nbt client
library to be used for low level processing of the nbtd server packets.
Other changes:
- made the socket library always set SO_REUSEADDR when binding to an
interface, to ensure that restarts of a server don't have to wait
for a couple of minutes.
- made the nbt port configurable. Defaults to 137, but other ports
will be useful for testing.

themselves are run as a single process, but run as a child of the
main process when smbd is run in the standard model, and run as part
of the main process when in the single mode.
- rewrote the winbind template code to use the new task services. Also
fixed the packet queueing
- got rid of event_context_merge() as it is no longer needed

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

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.

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.

- this creates a new task and then starts a process_model "single"
with service "winbind_task"
- that means with -M single everything is in one process
with - M standard winbind is a seperate process but didn't fork for each connection
with -M thread winbind is a seperate thread but didn't thread for each connection
- the dummy server listen s on /tmp/.winbind/echo
and for better testing with telnet also on 127.0.255.1 port 55555

- stream_socket services
the smb, ldap and rpc service which sets up a srtam socket end then
waits for connections
and
- task services
which this you can create a seperate task that do something
(this is also going through the process_model subsystem
so with -M standard a new process for this created
with -M thread a new thread ...
I'll add datagram services later when we whave support for datagram sockets in lib/socket/
see the next commit as an example for service_task's

- 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)

the hierarchy in the init functions is correct now

Both subsystems and modules can now have init functions, which can be
specified in .mk files (INIT_FUNCTION = ...)
The build system will define :
- SUBSYSTEM_init_static_modules that calls the init functions of all statically compiled modules. Failing to load will generate an error which is not fatal
- BINARY_init_subsystems that calls the init functions (if defined) for the subsystems the binary depends on
This removes the hack with the "static bool Initialised = " and the
"lazy_init" functions

- use #include <XXX.h> for operating system includes
- use includes relative to include/ for things like system/wait.h
also fixed the thread backend to work somewhat. To fix it properly we need to do this:
- add a configure test for support for thread local storage (the __thread keyword)
- refuse to do pthreads if tls doesn't work
- refuse to do pthreads if seteuid() affects process instead of thread
- defined THREAD_LOCAL as __thread when WITH_PTHREADS
- add THREAD_LOCAL to all the global data structures that should be
thread local (there are quite a few)
right now the thread backend falls over when you hit it with several
connections at once, due to the lack of __thread on some critical
structures.

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.
