Johannes Schindelin 07ea90a5d2 Cygwin: Do not show Error dialogs by default
...in a non-Cygwin child process.  Backported from MSYS2.
Downstream commit message follows.

In https://github.com/msys2/msys2-runtime/pull/18, we discussed a change
that would allow default Windows error handling of spawned processes to
kick in (such as registered JIT debuggers). We even agreed that it would
make sense to hide this functionality behind a flag, `winjitdebug`.

However, when this got upstreamed as 21ec498d7f (cygwin: use
CREATE_DEFAULT_ERROR_MODE in spawn, 2020-12-09), that flag was deemed
unnecessary.

But it would appear that it _is_ necessary: As reported in
https://github.com/msys2/MSYS2-packages/pull/2414#issuecomment-810841296
this new behavior is pretty disruptive e.g. in CI scenarios.

So let's introduce that `winjitdebug` flag (settable via the environment
variable `MSYS`) at long last.

Corinna Vinschen b2476bc523 Cygwin: globals: make __progname an alias of program_invocation_short_name
On Linux, __progname and program_invocation_short_name are just
different exported names of the same string.  Do the same in Cygwin.
This requires to tweak the mkglobals_h so as not to touch the
EXPORT_ALIAS expression.  Also, use the base variable
program_invocation_short_name throughout.  __progname is just
the export for getopt.

Corinna Vinschen 1f68e88f0d Cygwin: redefine how to recognize forkee state
So far the global variable in_forkee only indicated if the
process is the child process during fork(2) itself.

However, we need an indicator accessible from plain C code
in newlib, allowing to check for a process being a forked
process all the time, after fork(2) succeeded.

Redefine bool in_forkee to int __in_forkee to allow exposing
it to newlib.  Redefine how it indicates fork state (not
forked, forking, forked).

Corinna Vinschen 064e4bb8bb Cygwin: convert __collate_range_cmp to __wcollate_range_cmp
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=179721

After FreeBSD eventually picked up the bugreport from within
only 5 years, rename __collate_range_cmp to __wcollate_range_cmp
as suggested all along, and make it type safe (wint_t instead of
wchar_t for hopefully obvious reasons...)

While at it, drop __collate_load_error and fix the checks for
it in glob and fnmatch.

Corinna Vinschen 339bb6e932 Cygwin: stop handling files with .com suffix like .exe files
.com is a remnant from the past.  There are only five executables
left:

  chcp.com
  format.com
  mode.com
  more.com
  tree.com

Calling them on the command line already requires to use the
suffix anyway.  So drop useless .com test from the execve test
for scripts (they are handled earlier in the same function
as executables) and do not handle them like .exe suffixes in
other functions.

Ken Brown c2aa5b6d74 Cygwin: syscalls.cc: remove ".dll" from blessed_executable_suffixes
This reverts commit d9e9c7b5a7.  The latter added ".dll" to the
blessed_executable_suffixes array because on 32-bit Windows, the
GetBinaryType function would report that a 64-bit DLL is an
executable, contrary to the documentation of that function.

That anomaly does not exist on 64-bit Windows, so we can remove ".dll"
from the list.  Reverting the commit does, however, change the
behavior of the rename(2) syscall in the following unlikely situation:
Suppose we have an executable foo.exe and we make the call

  rename ("foo", "bar.dll");

Previously, foo.exe would be renamed to bar.dll.  So bar.dll would
then be an executable without the .exe extension.  The new behavior is
that foo.exe will be renamed to bar.dll.exe.  [Exception: If there
already existed an executable (not a DLL!) with the name bar.dll, then
.exe will not be appended.]

Corinna Vinschen 7f42498be6 Cygwin: rename __cygwin_environ and drop env redirection via cur_environ()
Back in early Cygwin development a function based access to the
environment was exported, the internal environ in Cygwin was called
__cygwin_environ and cur_environ() was used to access the environment
indirectly .  The history of that necessity is not documented,
but kept in i686 for backward compatibility.

The x86_64 port eventually used __cygwin_environ directly and exported
it as DATA under the usual name environ.

We don't need the i686 workaround anymore, so just rename
__cygwin_environ to environ, drop the cur_environ() macro and
simply export environ under its own name.

Takashi Yano f6db6f52ae Cygwin: pinfo: Fix exit code for non-cygwin apps which reads console.
- The recent commit "Cygwin: pinfo: Fix exit code when non-cygwin app
  exits by Ctrl-C." did not fix enough the issue. If a non-cygwin app
  is reading the console, it will not return STATUS_CONTROL_C_EXIT
  even if it is terminated by Ctrl-C. As a result, the previous patch
  does not take effect.
  This patch solves this issue by setting sigExeced to SIGINT in
  ctrl_c_handler(). In addition, sigExeced will be cleared if the app
  does not terminated within predetermined time period. The reason is
  that the app does not seem to be terminated by the signal sigExeced.

Takashi Yano 9e4d308cd5 Cygwin: pipe: Adopt FILE_SYNCHRONOUS_IO_NONALERT flag for read pipe.
- With this patch, FILE_SYNCHRONOUS_IO_NONALERT flag is applied to
  the read pipe so that native C# programs work with cygwin pipe.
  To handle signals in reading pipe with this flag set, the read
  pipe itself is always set to nonblocking mode and simulates the
  blocking behaviour in raw_read().

- Default to byte mode rather than message mode in order to make
  C# programs work with cygwin pipe.

Corinna Vinschen b62450cf17 Cygwin: POSIX msg queues: implement open/mq_open entirely in fhandler
The mq_open call is just a framework now.  This patch moves the
entire functionality into fhandler_mqueue.  To support standard
OS calls (as on Linux), make fhandler_mqueue a derived class from
fhandler_disk_file and keep the base handle the handle to the
default stream, to allow implementing O_PATH functionlaity as well
as reading from the file and NOT reading binary message queue data.

Implement a standard fhandler_mqueue::open method, allowing, for
instance, to touch a file under /dev/mqueue and if it doesn't exist,
to create a message queue file.

FIXME: This introduces a BAD HACK into path_conv::check, which needs
reviewing.

Keep the posix path intact in the fhandler, and change get_proc_fd_name
accordingly to return only the basename plus leading slash for
/proc/<PID>/fd.

Corinna Vinschen e42f66d00f Remove ill-advised cygwin_props
Cygwin_props have been invented to allow switching off the unique
installation keys in the first place, supposedly for debugging.
This never really was a good idea, after all we *want* the installations
to be independent and there's no good reason to break that, not even
for debugging purposes.

Other than that, cygwin_props were meant to be used for some other global
settings which never took place.  There's just no good reason to tweak
the DLL binary invisibly where a setting could be done in a file or the
environment.

This patch removes the cygwin_props entirely, including the related
settings in cygcheck.

handle.
