I've now retested conpty v6 and it has much improved since the previous
version I tested, thank you very much.
The only 2 issues that I still observe are that character set conversion
within a terminal is hard-targeted towards UTF-8, and one case of input
stalling when using ReadConsole from a cygwin-compiled program.
Test results:
resize terminal while running Windows cmd
âworks
run cmd, run dir/P: works
signal handling/mediation
â^Z is properly caught e.g. when running notepad
character set conversion from Windows cmd line program
âworks: xcopy (â German error message)
â¯non-ASCII output fails in non-Unicode mintty
The following cases refer to wincon.c, compiled with x86_64-w64-mingw32-gcc:
output: WriteConsoleW
âworks in Unicode mintty
â¯non-ASCII output fails in non-Unicode mintty
output: SetConsoleTextAttribute character attributes
âworks
input: ReadConsoleW
âworks in Unicode mintty
The same program, compiled with cygwin gcc, fails in mintty:
output is skipped (like without the patch)
â¯input stalls, kill -9 fails.
Without conpty patch v6, both output and input are skipped.
Note that winpty properly handles this case.
handling non-ASCII characters
â¯fails in cmd within non-Unicode mintty (LC_ALL=en_US mintty)
(echo ö, or type file with a properly encoded ö)
but does not stall anymore...
terminal reports in response to request escape sequences
("\033[6n", "\033[0c", "\033[>c", '\033[18t', '\033]10;?\033\')
âwork
output to alternate screen
âseems to work
before or while cmd.exe is running, echo "\033[?1047h" > /dev/pty...
to mintty from somewhere else, run dir...
