[PATCH 0/5] Some revisions for pty and console code.

Takashi Yano (5): Cygwin: pty: Add workaround for rlwrap 0.40 or later. Cygwin: console: Revise the code to switch xterm mode. Cygwin: pty: Make close_pseudoconsole() be a static member function. Cygwin: pty: Prevent pty from changing code page of parent console. Cygwin: pty: Make master

[PATCH 1/5] Cygwin: pty: Add workaround for rlwrap 0.40 or later.

- The workaround for rlwrap introduced by commit 8199b0cc does not take effect for rlwrap 0.40 or later. This patch add a workaround for rlwrap 0.40 or later as well. --- winsup/cygwin/fhandler_tty.cc | 5 + 1 file changed, 5 insertions(+) diff --git a/winsup/cygwin/fhandler_tty.cc

[PATCH 2/5] Cygwin: console: Revise the code to switch xterm mode.

- If application changes the console mode, mode management introduced by commit 10d8c278 will be corrupted. For example, stdout of jansi v2.0.1 or later is piped to less, jansi resets the xterm mode flag ENABLE_VIRTUAL_TERMINA_PROCESSING when jansi is terminated. This causes garbled output

[PATCH 3/5] Cygwin: pty: Make close_pseudoconsole() be a static member function.

- The function close_pseudoconsole() should be static so that it can be safely called in spawn.cc even after the fhandler_pty_slave instance has been deleted. That is, there is a problem with the current code. This patch fixes the issue. --- winsup/cygwin/fhandler.h | 3 ++-

[PATCH 4/5] Cygwin: pty: Prevent pty from changing code page of parent console.

- After commit 232fde0e, pty changes console code page when the first non-cygwin app is executed. If pty is started in real console device, pty changes the code page of root console. This causes very annoying result because changing code page changes the font of command prompt if console

[PATCH 5/5] Cygwin: pty: Make master thread functions be static.

- The functions pty_master_thread() and pty_master_fwd_thread() should be static (i.e. should not access class member) because the instance is deleted if the master is dup()'ed and the first master is closed. In this case, because the dup()'ed instance still exists, these master threads

[PATCH] Cygwin: pty: Set input_available_event only for cygwin pipe.

- cat exits immediately in the following senario. 1) Execute env CYGWIN=disable_pcon script 2) Execute cmd.exe 3) Execute cat in cmd.exe. This is caused by setting input_available_event for the pipe for non-cygwin app. This patch fixes the issue. --- winsup/cygwin/fhandler_tty.cc

[PATCH 06/11] cxx.cc: Fix dynamic initialization for static local variables
