the assumption of only one producer ((abs)moustratrack()) is not true for external mouse events from /dev/mousein, so protect the mouse state and queue with ilock(). get rid of mousecreate(), just use devcreate(). reset cursor when all instances of /dev/mouse and /dev/cursor got closed, instead of also considering /dev/mousectl. the reason is that kbdfs keeps the mousectl file open. so exiting a program that has the cursor changed will properly reset the cursor to arrow. don't access user buffer while holding cursor spinlock! the memory access can fault. theres also no lock needed there, we'r just copying *from* the cursor memory. fix use of strtol(), p will always be set, check for end of string. keep pointer coordinates onscreen (off by one). make lastms() function to get the last millisecond delta of last call for resynchronization. fix msg[3] buffer overflow in m5mouseputc(). get rid of mouseshifted logic, it is not used. |
