bind10-devel-20100812 released on August 12, 2010
84. [bug] jinmei, jerry
This is a quick fix patch for the issue: AXFR fails half the
time because of connection problems. xfrout client will make
a new connection every time. (Trac #299, svn r2697)
83. [build]*
The configure --with-boost-lib option is removed. It was not
used since the build included ASIO. (svn r2684)
82. [func] jinmei
bin/auth: Added -u option to allow the effective process user
of the authoritative server after invocation. The same option to
the boss process will be propagated to b10-auth, too.
(Trac #268, svn r2675)
81. [func] jinmei
Added a C++ framework for micro benchmark tests. A supplemental
library functions to build query data for the tests were also
provided. (Trac #241, svn r2664)
80. [bug] jelte
bindctl no longer accepts configuration changes for unknown or
non-running modules (for the latter, this is until we have a
way to verify those options, at which point it'll be allowed
again).
(Trac #99, r2657)
79. [func] feng, jinmei
Refactored the ASIO link interfaces to move incoming XFR and
NOTIFY processing to the auth server class. Wrapper classes for

a remote server. (Trac #218, svn r2038)
49. [func]* jelte
Use unix domain sockets for msgq. For b10-msgq, the command
line options --msgq-port and -m were removed. For bind10,
the -msgq-port option was removed, and the -m command line
option was changed to be a filename (instead of port number).
(Trac #183, svn r2009)
Use unix domain sockets for msgq. (Trac #183, svn r2009)
48. [func] jelte
bin/auth: Use asio's io_service for the msgq handling.

/// On success the user ID of the process is changed to the specified user,

/// \c username can be either a textual user name or its numeric ID.
/// If the specified user name (or ID) doesn't specify a local user ID

/// This function internally uses system libraries that do not guarantee

/// The behavior is undefined if this function is called from multiple threads
