* Fix spawned process window not foregrounding.Kaz Kylheku2017-11-162-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | This patch addresses an issue whereby the window of a process created with CreateProcess fails to come to the foreground. This occurs when the calling process itself hasn't run any Windows event processing loop. A repro test case is to make a program with a main, and and call CreateProcess to spawn calc.exe or notepad.exe before doing anything else. It turns out that a dummy call to TranslateMessage makes this issue goes away. If such a call is made before CreateProcess, then the spawned process' window comes up in the foreground as expected. * winsup/cygwin/Makefile.in (DLL_IMPORTS): We need to link in user32.dll to call TranslateMessage. Condense the multiple ${shell ...} call repetition with a foreach. * winsup/cygwin/spawn.cc (child_info_spawn::worker): Do the dummy TranslateMessage call before the section of code that calls CreateProcess or CreateProcessAsUser.
* Console: provide VT100-like end-of-line print behavior.Kaz Kylheku2017-11-162-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the majority of VT100-like terminals, when you print a character in the last column, the cursor sits in a kind of "limbo", as if the cursor position were one column past the edge of the screen. Thus when a line feed is output next, the cursor is then at the start of the next line. The Win32 console write doesn't do this; the cursor position wraps to the start of the next line. If a newline is put out, it translates to an extra newline going to the next-next line. This spoils the behavior of programs which depend on the VT100 behavior. In this patch, the VT100 behavior is simulated as follows. A new flag in the dev_console structure is set when a character is output to the last column. This flag is then observed in order to discard a newline (or rather any character which is mapped mapped to the DWN action). * winsup/cygwin/fhandler.h (class dev_console): New boolean data member, eat_newline. This indicates that if a character is output which moves down to the next line, it should be discarded rather than sent to the console. * winsup/cygwin/fhandler_console.cc (fhandler_console::write_normal): Set the eat_newline flag if the text output ends up at column zero. Honor the eat_newline flag when processing a DWN character, and clear it when processing certain other control characters.
* Report as CYGNAL in uname syscall.Kaz Kylheku2017-11-161-1/+1
| | | | | | | | This allows applications to distinguish whether they are running on the stock Cygwin or Cygnal. * winsup/cygwin/uname.cc (uname): sysname is now filled in with CYGNAL_ prefix rather than CYGWIN_.
* Cygnal apps use cmd.exe, not /bin/sh.Kaz Kylheku2017-11-163-47/+13
| | | | | | | | | | | | | | | | | | | * winsup/cygwin/include/paths.h (_PATH_CMDEXE): New preprocessor symbol. * winsup/cygwin/spawn.cc (av_setup): Use _PATH_CMDEXE rather than "/bin/sh". * winsup/cygwin/syscalls.cc (system): Spawn _PATH_CMDEXE with /c option rather than /bin/sh. (ETC_SHELLS): Preprocessor symbol removed. (shell_fp): Global variable removed. (getusershell): Don't open ETC_SHELLS, just march through static array of shell names. That array contains only one entry: _PATH_CMDEXE. (setusershell, endusershell): Remove references to shell_fp. (popen): Exec _PATH_CMDEXE rather than "/bin/sh", and the option is /c.
* When spawning, don't try to make invisible window.Kaz Kylheku2017-11-161-2/+0
| | | | | | | | | * winsup/cygwin/spawn.cc (child_info_spawn::worker): Do not call fhandler_console::need_invisible. It's not working properly. In an application which has no console because it was compiled -mwindows, calling this funcion causes a visible console window to appear. We don't need this in Cygnal; the Microsoft spawn functions don't pop up such windows.
* Use wShowWindow when calling CreateProcess.Kaz Kylheku2017-11-161-1/+2
| | | | | | * winsup/cygwin/spawn.cc (child_info_spawn::worker): Add STARTF_USESHOWWINDOW to dwFlags of the STARTUPINFOW structure, and set wShowWindow to SW_SHOWNORMAL.
