2007-10-18RIP BOOL. Convert BOOL -> bool. I found a few interestingJeremy Allison1-1/+1
bugs in various places whilst doing this (places that assumed BOOL == int). I also need to fix the Samba4 pidl generation (next checkin). Jeremy. (This used to be commit f35a266b3cbb3e5fa6a86be60f34fe340a3ca71f)

2007-10-10r23410: Merge the core of the cluster code.Volker Lendecke1-0/+41
I'm 100% certain I've forgotten to merge something, but the main code should be in. It's mainly in dbwrap_ctdb.c, ctdbd_conn.c and messages_ctdbd.c. There should be no changes to the non-cluster case, it does survive make test on my laptop. It survives some very basic tests with ctdbd enables, I did not do the full test suite for clusters yet. Phew... Volker (This used to be commit 15553d6327a3aecdd2b0b94a3656d04bf4106323)

2007-10-10r23204: Add MSG_SMB_BRL_VALIDATE. Tridge, this is a bit different from your bzrVolker Lendecke1-1/+1
branch, please check if it fulfils your needs. Two changes: The validation is not done inside the brlock.c traverse_fn, it's done as a separate routine. Secondly, this patch does not call the checker routines in smbcontrol directly but depends on a running smbd. (This used to be commit 7e39d77c1f90d9025cab08918385d140e20ca25b)

2007-10-10r23117: Factor out local messaging.Volker Lendecke1-399/+26
This removes message_block / message_unblock. I've talked to Jeremy and Günther, giving them my reasons why I believe they have no effect. Neither could come up with a counter-argument, so they go :-) (This used to be commit a925e0991ffbaea4a533bab3a5d61e5d367d46c8)
2007-10-10r23112: Trim down the message.c API slightly: The messages_pending_for_pid ↵Volker Lendecke1-56/+41
is now replaced by MSG_FLAG_LOWPRIORITY or'ed into the msg_type. To enable this, changed the msg_type definitions to hexadecimal. This way we could theoretically add the MSG_FLAG_NODUPLICATES again, but I would rather not do this, because that one is racy and can't be guaranteed at all.

2007-10-10r23055: Rewrite messages.c to use auto-generated marshalling in the tdb. I'mVolker Lendecke1-330/+267
doing this because for the clustering the marshalling is needed in more than one place, so I wanted a decent routine to marshall a message_rec struct which was not there before. Tridge, this seems about the same speed as it used to be before, the librpc/ndr overhead in my tests was under the noise. Volker (This used to be commit eaefd00563173dfabb7716c5695ac0a2f7139bb6)

2007-10-10r23024: Ok, neither the duplicates_allowed nor the timeout argument toVolker Lendecke1-112/+12
message_send_pid is used anymore. Two users of duplicates_allowed: winbind and the printer notify system. I don't thing this really changes semantics: duplicates_allowed is hell racy anyway, we can't guarantee that we don't send the same message in sequence twice, and I think the only thing we can harm with the print notify is performance. For winbind I talked to Günther, and he did not seem too worried. Volker (This used to be commit 75b3ae6a761c33ae6a70799340a1e8c1edea265e)
2007-10-10r23023: Get rid of the only caller of message_send_pid_with_timeout(). This ↵Volker Lendecke1-10/+0
replaces the timeouts on the individual message send calls with an overall timeout on all the calls. The timeout in message_send_pid_with_timeout() did not make much sense IMO anyway, because the tdb_fetch() for the messages_pending_for_pid was blocking in a readlock anyway, we "just" did the timeout for the write lock. This new code goes through the full wait for the write lock once and then breaks out of sending the notifies instead of running into the timeout per target. Jerry, please check this!

2007-10-10r22761: This introduces lib/conn_tdb.c with two main functions: ↵Volker Lendecke1-2/+2

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.

2007-10-10r20165: Change messaging subsystem to only allow one messageJeremy Allison1-3/+11

2007-10-10r20160: Fix long-standing (ie. from initial code I think) bugJeremy Allison1-2/+5
in tdb message processing. If we're inside a dispatch function and we delete our own handler we'd walk onto the next pointer from a deleted memory block. Fixes crash bug in winbindd (and goodness knows where else). Jeremy. (This used to be commit 27a4c1121404e346432d90b97b518861e038e9f2)

calls make it : become_root_uid_only() operation unbecome_root_uid_only() saving errno across the second call. Most of our internal change calls can be replaced with these simple calls. Jeremy (This used to be commit 4143aa83c029848d8ec741d9218b3fa6e3fd28dd)
2007-10-10r17293: After the results from the cluster tests in Germany,Jeremy Allison1-4/+24
fix the messaging code to call the efficient calls : save_re_uid() set_effective_uid(0); messaging_op restore_re_uid(); instead of using heavyweight become_root()/unbecome_root() pairs around all messaging code. Fixup the messaging code to ensure sec_init() is called (only once) so that non-root processes still work when sending messages. This is a lighter weight solution to become_root()/unbecome_root() (which swaps all the supplemental groups) and should be more efficient. I will migrate all server code over to using this (a similar technique should be used in the passdb backend where needed). Jeremy. (This used to be commit 4ace291278d9a44f5c577bdd3b282c1231e543df)

might be a big relief on messages.tdb contention as ignoring processes with >1000 messages in printing/notify.c should work correctly now. Jeremy, Jerry told me to ask you about printer scalability torture tests, this might be a reason why you implemented the message_send_pid_with_timeout using the signal (shudder) in the first place. :-) While looking at that... Wouldn't it be better to not use the signal but have an overall timeout for print_notify_send_messages using GetTimeOfDay & friends and not use the alarm signal deep inside tdb.c?
