commit 35313c0aa3fbfdd943edfb7bafd7645b1a0c54e9
Author: Andrew Bartlett <[EMAIL PROTECTED]>
Date: Mon Feb 4 17:59:16 2008 +1100
Remaining changes to implement the prefork process model
To use, run 'smbd -M prefork'
By default, only the smb service is preforked. 4 children are
created, and all listen for new connections. The Linux Kernel 'wake
one' behaviour should ensure that only one is given the oportunity to
accept. We need to look into the ideal number of worker children, as
well as load balancing behaviours.
To change, set:
prefork children : smb = 6
valid service names (smb in this example) match those in 'server services'.
Andrew Bartlett and David Disseldorp
commit c961e7d74e33a0dd61b1053620fb41521322e20d
Author: Andrew Bartlett <[EMAIL PROTECTED]>
Date: Mon Feb 4 17:53:01 2008 +1100
Rework process_single.c to take advantage of cluster_id() now taking an
additional argument.
Andrew Bartlett and David Disseldorp
commit 931994a7f185bbc98924823e9e8cef1011dd0957
Author: Andrew Bartlett <[EMAIL PROTECTED]>
Date: Mon Feb 4 17:51:38 2008 +1100
Rework cluster_id() to take an additional argument, as we need
<node>.<pid>.<fd> to be unique in a prefork process environment.
Andrew Bartlett and David Disseldorp
commit 0d830580e3539c96da3aa6c72fafe6eacd7a74a0
Author: Andrew Bartlett <[EMAIL PROTECTED]>
Date: Mon Feb 4 17:48:51 2008 +1100
Rework service init functions to pass down service name. This is
needed to change prefork behaviour based on what service is being
started.

Date: Wed Jan 16 09:45:29 2008 +1100
Allow the 'extra' objectclass added to objectClass attributes by
ldb_map to be modified (or omitted).
This should allow the current abuse of extensibleObject to be replaced
by a normal objectClass, possibly samba4TOP
