although their app had exited. As it turns out it was a missing
implementation of the method _dbus_fd_set_close_on_exec() for windows.
It's been tested with msvc2005, msvc2008, and mingw, and solves
all the unregistering issues on many kde apps.
In my informal studies of "normal" sets of match rules, only checking
match rules with the appropriate interface for the message reduces the
number that need to be checked by almost 100x on average (ranging from
halving for messages from the bus daemon, to a >200x reduction in many
cases). This reduces the overhead added to dispatching each message by
having lots of irrelevant match rules.
This is currently not a big deal, but will make more of a difference
once the set of match rules is partitioned by more features than just
the message type.
A variety of system components have migrated from legacy init into DBus
service activation. Many of these system components "daemonize", which
involves forking. The DBus activation system treated an exit as an
activation failure, assuming that the child process which grabbed the
DBus name didn't run first.
While we're in here, also differentiate in this code path between the
servicehelper (system) versus direct activation (session) paths. In
the session activation path our error message mentioned a helper
process which was confusing, since none was involved.
Based on a patch and debugging research from Ray Strode <rstrode@redhat.com>
Handle those WinSock errors that match the errno values handled. Don't
bother handling those errors that are mapped to DBUS_ERROR_FAILED in
the switch as that is the default return value anyway.
Replace dbus_daemon_init() by dbus_publish_session_bus_address(),
publishing the full address. Omit username from mutexes (not necessary
as mutex names are local to session). Don't exit if publishing the
address failed (allow multiple session bus instances per
session). Based on 00ee92ae314 by Tor Lillqvist.
Cherry-picked from commit 23945513e9a4da61d286ebfbce3897aa061ddbfe in
the dbus4win repository by tml@iki.fi. Remove claim of that commit not
being merged from README.dbus4win.
Remove unused functions, or put in #if 0 if potentially useful. Make
internal functions used just in one file static. Use -Werror after all
also on Windows. Construct the installation root from the location of
the dbus DLL, not from the location of the program .exe of the
process.
I didn't cherry-pick the commit from dbus4win that introduced
DBUS_DIR_SEPARATOR, as I think it just uglifies the code with little
gain. (Forward) slashes work fine on Windows.
