Issue: Earlier change missed "return" calls that will end up ignoring singleton logic and re-running console handle generation logic multiple times, leaking previously created handles in the process.
Fix: Add the missing "return" calls
With recent changes, PTY sessions are no longer working. The issue is due to TTY code in ssh.exe assuming that stdin and stdout are console handles. The reality could be different since these handles always are dup'ed or closed for other reasons.
Fix involves extracting console handles via CreateFile(CONIN\CONOUT).
- Logic to support conpty (currently disabled until validation is complete)
- fdopen() and fchmod() support for file handles
- support for auto updating known_hosts via ssh and ssh-keygen
- Support for dynamic Windows-size changes with PTY
- Changes to support OneCore SDK
- Test cases
To prevent screwing up terminal settings on windows when printing to the terminal, turn off the virtual termial before print out to console. The file call these funtions are from scp.c, sftp.c and sshconnect(calls smprintf). The virtual termial are not enabled in scp and sftp. turn off it in vfmprintf is enough for now.
#576 - fix the EVENT_CONSOLE_CARET issue.. Wrongly read the X, Y coordinates
#575 - when backspace key is pressed then screen is not refreshed correctly
#574 - when delete key is pressed then screen is not refreshed correctly (the last character is repeated in the end)
#573 - while using up/down arrows, screen is not refreshed correctly (there are some left over characters of bigger command)
#572 - clear screen is not clearing the whole console
#571 - Move the cursor to top of visible window so that nothing will be erased on the console.
#570 - code cleanup for console related logic
#569 - wrong implementation of TIOCGWINSZ. This is causing lot of issues when windows open ssh client is connecting to linux ssh server.
#568 - Scrolling issue when the cursor is at the last line of the visible window.
#567 - Logic to pass the raw buffer to console is wrong.
