* Fix OPOST for non-Cygwin pty slavesTakashi Yano2015-04-235-19/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * fhandler.h (class fhandler_base): Add virtual function get_io_handle_cyg() to get handle from which OPOST-processed output is read on PTY master. (class fhandler_pty_slave): Add variable output_handle_cyg to store a handle to which OPOST-processed output is written. Add two functions, i.e., set_output_handle_cyg() and get_output_handle_cyg(), regarding variable output_handle_cyg. Now, output_handle is used only by native windows program. The data before OPOST-processing is written to output_handle and OPOST-processing is applied in the master-side. For a cygwin process, OPOST-processing is applied in the slave-side, and the data after OPOST-processing is written to output_handle_cyg. (class fhandler_pty_master): Add two variables, i.e., io_handle_cyg and to_master_cyg, to store handles of a pipe through which OPOST-processed output passes. Add pty_master_fwd_thread and function pty_master_fwd_thread() for a thread which applies OPOST-processing and forwards data from io_handle to to_master_cyg. Add function get_io_handle_cyg() regarding variable io_handle_cyg. Now, the pipe between io_handle and to_master are used only by native windows program for applying OPOST-processing in the master-side. For a cygwin process, the pipe between io_handle_cyg and to_master_cyg is used for passing through the data which is applied OPOST-processing in the slave-side. * fhandler_tty.cc (struct pipe_reply): Add member to_master_cyg. (fhandler_pty_master::process_slave_output): Read slave output from io_handle_cyg rather than io_handle. (fhandler_pty_slave::fhandler_pty_salve): Initialize output_handle_cyg.

(fhandler_pty_master::close): Print to_master_cyg as well in debug message. Terminate master forwarding thread. Close handles to_master_cyg and io_handle_cyg. (fhandler_pty_master::ioctl): Use io_handle_cyg rather than to_master. (fhandler_pty_master::pty_master_thread): Add code for duplicating handle to_master_cyg. (fhandler_pty_master::pty_master_fwd_thread): New function for a thread to forward OPOST-processed data from io_handle to to_master_cyg. This thread applies OPOST-processing to the output of native windows program. (::pty_master_fwd_thread): Ditto. (fhandler_pty_master::setup): Create a new pipe to pass thruegh OPOST- processed output. Create new thread to forward data from io_handle to to_master_cyg. Set handle to_master_cyg to tty. Print io_handle_cyg as well in debug message. Close handles io_handle_cyg and to_master_cyg in case of error. (fhandler_pty_master::fixup_after_fork): Set handle to_master_cyg to tty. Copy handle to_master_cyg from arch->to_master_cyg.

* Try to make sure struct _mcontext is 16-byte alignedJon TURNEY2015-04-233-3/+8
| | | | | | | | | | | | | | | | | | On x86_64, RtlCaptureContext() uses fxsave to save FPU/MMX/SSE state. fxsave requires that the destination address is 16-byte aligned, or it will fault. CONTEXT is already annotated __attribute__ ((aligned (16))), do the same with struct _mcontext.
