virtual void open(CServer*);
virtual void close();
fixed handling of jumping to primary when screen saver starts and back to secondary when it stops. also now redirecting keyboard input to root window when screen saver starts; this allows the user to type in the lock dialog and also effectively discards any input used to deactivate the screen saver.
2002-06-24 03:24:22 +04:00
virtual void enter(SInt32 xAbsolute, SInt32 yAbsolute, bool);
changes to add command line arguments. also added automatic 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.

virtual bool leave();
fixes, mainly for windows. first, had to add a notification from 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.

added support for locking to a screen when the sroll lock is toggled on or when any key or button is pressed. fully implemented on X but stubbed out for now on win32.

// CXWindowsScreen overrides
added better handling of X server disconnecting unexpectedly. 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.

virtual void onOpenDisplay(Display*);
checkpoint. changed clipboard model. the clipboard can only 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.

Added hack to handle "half-duplex" caps-lock key on powerbook. That key only reports press when pressed and released when caps-lock is activated and only reports release when pressed and released when caps-lock is deactivated. I don't know of a way to detect this behavior so it may have to be configured by the user. The code assumes normal behavior; will have to add code to set the flag (perhaps from a user configuration).

checkpoint. adding screen saver support. only on X so far 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).

fixed bugs in mouse motion. wasn't taking care to capture all motion events relative to the previous mouse position. for example, if two mouse events arrive, the first at x+1,y and the second at x+2,y, we used to compute deltas of 1,0 and 2,0 instead of 1,0 and 1,0. that's fixed. also worked around a bug (probably) in windows that caused a motion event after a SetCursorPos() to be lost or reported one pixel off from the correct position. now using mouse_event() which doesn't have that problem. also fixed calculation of normalized coordinates for mouse_event() when there are multiple displays.
