* Remove env var translation; PATH semicolon separated.Kaz Kylheku2017-01-082-99/+9
| | | | | | | | | | | | | | | * winsup/cygwin/environ.cc (conv_envvars): Static array removed. (conv_start_chars): Likewise. (getwinenv): Function gutted to just return NULL. No environment vars require conversion. (match_first_char): Static function removed. (build_env): Removed logic for eliminating those variables that require donversion, since there are no such variables and the needed functions and arrays are gone. * winsup/cygwin/environ.cc (find_exec): Recognize semicolon as PATH separator.
* Arrange for text mode on stdin, stdout and stderr.Kaz Kylheku2016-09-171-4/+6
| | | | | | * newlib/libc/stdio/findfp.c (__sinit): Add the Cygwin-specific __SCLE (stream convert line endings) flag when calling the std function to initializing the reent structure's _stdin, _stdout and _stderr members.
* Replace bogus resize-window-to-clear-screen logic.cygnal-release-2.5.2Kaz Kylheku2016-07-272-31/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This removes (ab)uses of SetConsoleScreenBufferSize which sometimes cause cmd.exe to badly misbehave. It probably doesn't like the closely spaced timing of shrinking the window down to one line followed by a restore of the size. Instead we just output newlines to clear the window. * winsup/cygwin/fhandler.h (dev_console::scroll_window): Member function declaration removed. (dev_console::clear_should_scroll): New member function declared. * winsup/cygwin/fhandler_console.cc (dev_console::scroll_window): Member function removed. (dev_console::clear_should_scroll): New member function. Performs only the test that was performed by scroll_window, not the actual scrolling. The scrolling is now done in the caller in the fhandler_console class. (fhandler_console::clear_screen): Call con.clear_should_scroll instead of con.scroll_window. If this returns false, act as before. Otherwise, clear the screen by scrolling the window. This is done not by making SetConsoleScreenBufferSize calls to shrink and restore the window, but by earnestly emitting a number of carriage returns equal to the vertical screen size and then restoring the cursor position.
* Console: integrate end-of-line hack with cursor positioning.Kaz Kylheku2016-07-261-8/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | The previous work for simulating the beyond-right-edge of screen cursor position is incomplete without integrating this into the cursor positioning routines. By making the cursor routines aware of the eat_newline flag, we allow cursor movements to work correctly with regard to this simulated position. * winsup/cygwin/fhandler_console.cc (fhandler_console::cursor_set): If the X position is beyond the right edge of the screen, then set the cursor to the start of the following line, rather than clipping to the right edge, set the eat_newline flag, indicating that the the true position is actually one character beyond the previous line. In all other cases, clear the eat_newline flag. (fhandler_console::cursor_rel): Do not apply the delta vector to the raw Win32 cursor position; call cursor_get and apply it to the virtual cursor position which takes into account the eat_newline flag. (fhandler_console::cursor_get): Take into account the eat_newline flag. If it is set, then report an adjusted position that is one column beyond the end of the previous line.

| | | | | | | | | * winsup/cygwin/environ.cc (set_winsymlinks): Refer to CYGNAL variable in diagnostic message. (parse_options): Pass "CYGNAL" to setenv. (_addenv, environ_init): Call parse_options if variable name is "CYGNAL" rather than "CYGWIN". Comments updated. (spenvs): Change CYGWIN_DEBUG to CYGNAL_DEBUG.
* Implement sh -> cmd.exe translation hack.Kaz Kylheku2016-07-131-0/+15
| | | | | * winsup/cygwin/spawn.cc (spawnve): Rewrite /bin/sh -c cmd invocations to use cmd.exe /c cmd instead.
* Default stdio streams to text mode.Kaz Kylheku2016-07-121-2/+2
| | | | | | | | * newlib/libc/stdio/flags.c (__sflags): Enable for Cygwin the piece of code which adds the O_TEXT mode if O_BINARY is not present. And, also, fix that piece of code's incorrect use of the | operator to test a flag instead of &.
* Implement drive-relative paths and per-drive working dir.cygnal-release-2.5.1.98cygnal-release-2.4.98Kaz Kylheku2016-07-111-2/+42
| | | | | | | | | | | | | | | | | | | | | | * winsup/cygwin/path.cc (normalize_win32_path): When a drive-relative path is normalized, look up the remembered working directory of that drive in the environment. A drive-relative path is, for example, "C:file.txt". Or just "C:", with no component. If there is no path for the drive in the environment, then the root directory is used, and the "C:" part thus becomes "C:\", causing the path to refer to "C:\file.txt". Otherwise the path is inserted, with a backslash, like "C:\users\bob\file.txt". The Windows convention for storing these per-drive paths in the environment is to use environment variables based on drive letters. For instance the path for the C drive is stored in the environment variable "!C:" (bang, letter, colon). The path includes the C:\ prefix. (cwdstuff::override_win32_cwd): Add the behavior of associating the current working directory with its drive (if it is a current working directory based on a drive). For instance if the overriding cwd is "C:\Users", then the "C:\Users" path is stored into the "!C:" environment variable.
* Remove conversion of native paths to POSIX mount points.Kaz Kylheku2016-07-101-74/+1
| | | | | | | | | | | | We don't want the behavior in Cygnal whereby a native path like C:\path\to\app is converted to /app in getcwd and other situations, or C:\random\path is converted to /cygdrive/c/random/path. * winsup/cygwin/mount.cc (mount_info::conv_to_posix_path): Remove entire section of code which scans mount points, mapping native paths to their mount points paths. All we do is "slashify" and exit.
* First steps toward native path handling.Kaz Kylheku2016-07-084-32/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - /proc and /dev are are still available, accessed as proc:/ and dev:/ - All other paths are native, and do not "see" virtual Cygwin items; /cygdrive is just C:\cygdrive (if the current drive is C). - chdir() to a virtual directory like dev:/ or proc:/ results in errno EOPNOTSUPP. * winsup/cygwin/mount.cc (mount_info::conv_to_win32_path): Takes new bool argument, hide_cygwin_virtuals. If true all that the function does is "backslashify" the path. (mount_info::add_item): Special hack inserted here so that we can create the virtual root directory which holds dev and proc and whatnot, and is passed here as "/". We cannot let this go through normalize_posix_path any more because it will turn to C:\. * winsup/cygwin/mount.h (mount_info::conv_to_win32_path): Declaration updated. * winsup/cygwin/path.cc (is_posix_space): New static function: tests for paths in special spaces, currently "dev:/" and "proc:/". Used by normalize_posix_path. (normalize_posix_path): Any path that doesn't satisfy the is_posix_space test is treated as Win32. Since the bulk of the code is now only used for these spaces, the relative path handling is not required and a the corresponding block of code is removed. Paths satisfying is_posix_space are transformed. I.e. the underlying path resolution machine in the path_conv class still recognizes /proc and /dev. It's just that these will not occur, because normalize_posix_path will convert them to references with drive names. (path_conv::check): Pass the is_msdos flag down to mount_info::conv_to_win32_path as the new argument. Thus if normalize_posix_path indicates a native path, this function will hide the virtual spaces. Also, we add PATH_NOPOSIX and PATH_NOACL to the object's path_flags. This is used in chdir. (normalize_win32_path): A small piece of logic works against our plan here: it checks for the leading forward slash on the path, and prevents such paths from being converted to Win32 paths with a drive reference. We eliminate this test, and treat paths unconditionally. (chdir): Here, if the path is not native, we return EOPNOTSUPP. Thus it is impossible to chdir into Cygwin virtual directories like /dev (now referenced as dev:/). They can be listed but not turned into the current directory. Eventually we want chdir to actually set the Win32 current directory of the process; that can't work for virtual dirs. * winsup/cygwin/path.h (path_conv::is_native): New inline accessor which tests for the PATH_NOPOSIX flag.
* Small fixes in get_cmd_exe_path.Kaz Kylheku2016-07-081-11/+13
| | | | | | | | | | * winsup/cygwin/spawn.cc (init_cmd_exe_path): Restructure code to initialize rather than assign nchars. Include backslash in cmd.exe name; then it can be omitted from the size calculation and sprintf. Do not allocate an excess byte for the string. Thanks to user forsvarir of the code review stackechange. Also reformatted to the GNU style used inside Cygwin. (init_cmd_exe_path): Remove spurious whitespace.
* More secure way of obtaining command interpreter.Kaz Kylheku2016-07-073-4/+30
| | | | | | | | | | | | | | | | | | Instead of relying on the COMSPEC environment variable, what we can do is assume that the program is called "cmd.exe", and then look for it in the directory reported by the GetSystemDirectoryA Win32 function in kernel32.dll. * winsup/cygwin/path.h (get_cmd_exe_path): New function declared. * winsup/cygwin/spawn.cc (av::setup): Use get_cmd_exe_path instead of getenv("COMSPEC"). (cmd_exe_path): New static variable. (init_cmd_exe_path): New static function. (get_cmd_exe_path): New function. * winsup/cygwin/syscalls.cc (system, getusershell, popen): Use get_cmd_exe_path instead of getenv("COMSPEC").
* Use COMSPEC env var, not hard-coded CMD.EXE path.Kaz Kylheku2016-07-073-19/+25
| | | | | | | | | | | | | | | | | | | | It is with some reluctance I make this change, due to the security implications of relying on environment variables. But we can't have a hard-coded path. * winsup/cygwin/include/paths.h (_PATH_CMDEXE): Macro removed. * winsup/cygwin/spawn.cc (av::setup): Use COMSPEC environment variable instead of hard-coded path. If missing, bail with errno set to EOPNOTSUPP. * winsup/cygwin/syscalls.cc (system): Use COMSPEC environment variable. If missing, return -1. (getusershell): Eliminate static array of shell names. If shell_index is zero, return value of COMSPEC env var, if it exists, and increment shell_index to 1. (popen): Use COMSPEC and if that is missing, set errno to EOPNOTSUPP and return NULL.
* Fix previous VT100 fix.Kaz Kylheku2016-07-021-11/+11
| | | | | | | | | We must only set or clear the eat_newline flag if we output something. * winsup/cygwin/fhandler_console.cc (fhandler_console::write_normal): Move the flag setting code inside the if statement which performs output.
* Fix spawned process window not foregrounding.Kaz Kylheku2016-07-022-1/+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 Kylheku2016-07-012-0/+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 Kylheku2016-07-011-1/+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 Kylheku2016-06-303-47/+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 Kylheku2016-06-301-2/+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 Kylheku2016-06-301-1/+2
| | | | | | * winsup/cygwin/spawn.cc (child_info_spawn::worker): Add STARTF_USESHOWWINDOW to dwFlags of the STARTUPINFOW structure, and set wShowWindow to SW_SHOWNORMAL.

* Use correct file info (especially inode number) for newly created filesCorinna Vinschen2016-06-211-3/+9
| | | | | | | | | | | | | | fhandler_base::open_fs has two problems: - When newly creating a file, the file info in the path_conv is incorrect. It points to info for the parent dir, not to info for the file itself (which, naturally, wasn't available before). - Fetching the file's inode number only worked for non-NFS. Both problems should be fixed now by reloading file info if the file has just been created, as well as using the new FS-agnostic path_conv::get_ino method.

| | | | | | | | | | | Rather than having to check for the FS type in the caller and having to call different functions whether FS is NFS or not, encapsulate the info in path_conv_handle/path_conv methods to allow FS type agnostic calling from upper level functions.

* 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.

* Return at most one line of input in canonical modeTakashi Yano2016-06-061-6/+5
| | | | | | | | | | | | | | | | | 'man termios' says: "A read(2) returns at most one line of input" in canonical mode. On cygwin 2.5.1, read(2) returns all data in buffer if the buffer size specified is large enough. This behaviour is correct in noncanonical mode, but is not correct in canonical mode. While checking this problem, I found a bug of tcflush(). tcflush() flushes only partial data in the buffer. The patch also fixes this bug. The patch has also been tested against the problem reported in https://cygwin.com/ml/cygwin/2016-05/msg00318.html. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* Only regenerate tlsoffsets{64}.h if cygtls.h can be compiledCorinna Vinschen2016-06-061-1/+1
| | | | | | | | | | | | The rule to make tlsoffset{64}.h has a flaw. If cygtls.h can't be built for whatever reason, it *still* regenerates tlsoffsets{64}.h, just with size 0. If the bug is not in cygtls.h itself, this behaviour breaks further building, because fixing the problem won't result in regenerating tlsoffset{64}.h. Manual intervention is required. Fix that by removing tlsoffsets{64}.h if gentls_offsets fails. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

* arc: Rework default exception handlers for ARC EM and HSAnton Kolesov2016-05-251-73/+34
| | | | | | | | | | | | | | | | | | | | | | Initially crt0.S used a special function, declared as weak as a default exception handler in interrupt vector table. To let user override individual handlers, this function had multiple names - one for each IVT entry, which, however, was terribly confusing for the debugger and user - because it wasn't clear which symbol will be used as a function name in debugger. Defining multiple separate functions - one for each handler, would resolve the mess, but would increase code size of crt0.o. To clean this up, this patch defines exception handlers as weak symbols as well, but those are defined as just symbols, not functions, hence there would be less confusion over what is what. At the same time, users still can redefine exception handlers symbol by creating functions with respective names. libgloss/ 2016-05-24 Anton Kolesov <Anton.Kolesov@synopsys.com> * arc/crt0.S: Convert memory_error and friends to non-function symbols.
