* Simplify check for Alt-NumpadCorinna Vinschen2017-01-191-15/+5
| | | | | | | | | Create two new inline functions is_alt_numpad_key(PINPUT_RECORD) and is_alt_numpad_event(PINPUT_RECORD) which contain the actual checks. Call these functions from fhandler_console::read and peek_console for better readability. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Handle Alt+Numpad key sequences in console input and selectCorinna Vinschen2017-01-191-3/+23
| | | | | | | | | | | | | | | | | | | | {p}select/{p}poll completely ignored Alt+Numpad key sequences in console input which results in newer readline using pselect to fail handling such sequences correctly. See https://cygwin.com/ml/cygwin/2017-01/msg00135.html During debugging and testing it turned out that while reading console input, single key presses during an Alt+Numpad sequences where not ignored, so ultimately a sequence like Alt-down Numpad-1 Numpad-2 Numpad-3 whihc is supposed to result in a single character in the input stream will actually result in 4 chars in the input stream, three control sequences and the actual character. Both problems should be fixed by this patch. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Don't raise SIGTTIN from poll/selectCorinna Vinschen2016-07-271-2/+2
| | | | | | | | | | | | | SIGTTIN should be raised when read() is made on a tty in a backgrounded process, but not when it's tested with poll()/select(). I guess poll()/select() does need to call bg_check(), in order to detect the error conditions that notices (that is, if bg_check() returns bg_eof or bg_error, then fd is ready as an error condition exists) so add an optional parameter to fhandler_base::bg_select() to indicate that signals aren't desired. See https://cygwin.com/ml/cygwin-developers/2016-07/msg00004.html

* Improve timer handling in select.Corinna Vinschen2016-06-061-43/+50
| | | | | | | | | | | | | | | | | | | | | | | Commit a23e6a35d896a075640db714b28ce74bb6b8d7ff introduced a timer object to the WFMO handling in select_stuff::wait to allow sub-tickcount timeout values in select. Problems with this patch: The timer was created and destroyed on every invocation of select_stuff::wait, thus potentially multiple times per select. Also, since the timer was prepended to the WFMO hande list, the timer handle could shadow actual events on other objects, given that WFMO checks the objects in the order they have been specified in the HANDLE array. The timer was also created/destroyed and added to the HANDLE array even if it was not required. This patch drops the local timer HANDLE and recycles the cw_timer HANDLE in the cygtls area instead. Thus we typically don't need to create the timer in select at all, and we never have to destroy it. The timer HANDLE is now also appended as last object to the HANDLE array, and it's only added if actually needed. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
* Fix condition in select which results in busy loop.Corinna Vinschen2016-06-061-1/+1
| | | | | | | | | | | The check for current timestamp > start timestamp has an unwelcome side effect: The loop is not left as long as the current timestamp hasn't been incremented. This leads to busy loops of about one tick (10 to 16 ms per MSDN). This fixes https://cygwin.com/ml/cygwin/2016-05/msg00327.html Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

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.

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.
