[PATCH 2/2] Cygwin: pty: Disable clear screen on new pty if TERM=dumb or emacs*.

- Pseudo console support introduced by commit 169d65a5774acc76ce3f3feeedcbae7405aa9b57 shows garbage ^[[H^[[J in some of emacs screens. These screens do not handle ANSI escape sequences. Therefore, clear screen is disabled on these screens. --- winsup/cygwin/fhandler_tty.cc | 26

[PATCH v5 1/1] Cygwin: pty: Fix state management for pseudo console support.

- Pseudo console support introduced by commit 169d65a5774acc76ce3f3feeedcbae7405aa9b57 has some bugs which cause mismatch between state variables and real pseudo console state regarding console attaching and r/w pipe switching. This patch fixes this issue by redesigning the state

[PATCH v5 0/1] Fix PTY state management in pseudo console support.

Pseudo console support in test release TEST: Cygwin 3.1.0-0.3, introduced by commit 169d65a5774acc76ce3f3feeedcbae7405aa9b57, has some bugs which cause mismatch between state variables and real pseudo console state regarding console attaching and r/w pipe switching. This patch fixes this issue by

[PATCH 4/4] Cygwin: pty: Limit API hook to the program linked with the APIs.

- API hook used for pseudo console support causes slow down. This patch limits API hook to only program which is linked with the corresponding APIs. Normal cygwin program is not linked with such APIs (such as WriteFile, etc...) directly, therefore, no slow down occurs. However, console

[PATCH 3/4] Cygwin: pty: Move function hook_api() into hookapi.cc.

- PTY uses Win32 API hook for pseudo console suppot. The function hook_api() is used for this purpose and defined in fhandler_tty.cc previously. This patch moves it into hookapi.cc. --- winsup/cygwin/fhandler_tty.cc | 44 --- winsup/cygwin/hookapi.cc | 34

[PATCH 2/4] Cygwin: pty: Speed up a little hooked Win32 API for pseudo console.
