and untested. also some known problems: not detecting an
xscreensaver started after us and not detecting built-in
screen saver activation (not sure if we can without using
ugly extensions).
the address and port to listen on or connect to. changed the
default port and put it in ProtocolTypes.h. the HTTP port is
now no longer opened unless the --http argument is supplied
or the config file includes it.
restarting and daemonizing on unix. daemon sends log messages
to syslog. unix now reads config file from file named on
command line; if no command line arg then uses effective
user's config file and if that's not there it finally tries
/etc/synergy.conf. if there are no screens configured then
one is added for the primary screen. broke some startup
stuff on win32.
also now timing out if X primary screen can't grab the mouse
and keyboard. the server will just give up trying to switch
screens. the grabs will fail is some other app has a grab
and won't release it. note that kdm grabs the keyboard for
the duration that the login window is displayed, effectively
disabling synergy.
the apps still exit but they do it in a mostly controlled
manner. in particular, the server threads except the one
processing primary screen events will terminate gracefully.
this will be important should the server ever allow HTTP
clients to rewrite the configuration file.
note that X makes it effectively impossible to continue once
the X server disconnects. even if it didn't it would be
difficult for synergy to recover. users will have to add
synergy to the X display manager's startup script if they
expect the server to be restarted. alternatively, we could
add code to fork synergy at startup; the child would do
the normal work while the parent would simply wait for the
child to exit and restart it.
CServer to the primary screen when the configuration changes so it
can make necessary adjustments (the win32 primary screen must tell
the hook dll about the new jump zones).
changed includes of some std c++ library files to go through
our own include files. these wrap the include with stuff to
keep vc++ quiet when compiling at warning level 4, which is
what it does now. it also works around missing <istream> and
<ostream> on g++2.96.
added missing std:: where necessary. g++ doesn't really support
namespaces so it lets references without the namespace slip
through.
added workaround or fix. not sure if istringstream::str(string)
should reset eofbit. it does on g++ but does not on vc++.
added clear() after str() so it works either way.
added low-level keyboard hook to win32. if available (it's only
available on NT SP3 and up) it allows us to catch and handle
alt+tab, alt+esc, ctrl+esc, and windows key hot keys. i think
that leaves only ctrl+alt+del and accessibility functions
uncaught on those systems.
CXWindowsUtil that installs/uninstalls an X error hander.
using that in primary screen, clipboard, and util to ensure
that certain errors don't kill the app.
be accessed now between open()/close(). ownership of the
clipboard is asserted via the empty() method. this parallels
the win32 model (but the win32 code hasn't been updated yet).
refactored X11 clipboard code. moved the bulk of it into
CXWindowsClipboard and moved some comment event handling into
CXWindowsScreen. changed how requests are processed into a
hopefully easier to understand model. added support for getting
clipboard from and sending clipboard to motif (or at least
lesstif) clients. sending to lesstif required a hack to work
around an apparent bug in lesstif.
a screen. this allows the secondary screen to set it's
modifier state to match the primary screen's state. this is
not strictly necessary since each keystroke should adjust the
modifier state as needed to get the right result.
sending a sequence number with enter messages. screens use that
sequence number in clipboard grab and data messages. the server
uses the sequence number to order messages across clients. also
changed secondary screens to send clipboard updates on leaving
(or when grab occurs when not active) instead of on a query from
the server. primary effectively does the same. the query
message has been removed.
not detecting a change to clipboard when synergy window isn't
the owner (since there's no event for this; we'll have to
check when we leave the screen i guess). large transfers
don't seem to work.
