the -blocking option when closing. The windows pipe driver
now has the same behavior as the UNIX side. This change is
to avoid a hung shell when exiting due to open pipes that
refuse to close in a graceful manner.
* doc/open.n: Added a note about -blocking 0 and lack of
exit status as it had never been documented. [Bug 947693]
***POTENTIAL INCOMPATIBILITY***
Scripts that use async pipes on windows, must (like the
UNIX side) set -blocking to 1 before calling [close] to
receive the exit status.
* tests/winPipe.test (winpipe-6.1/2): added 'fconfigure $f
-blocking 1' so the exit status can be acquired.

This bug built a command line with a missing space between
tclpipe.dll and the following arguments. It caused error

symbol for every compile. Instead, define
TCL_PIPE_DLL only when compiling tclWinPipe.c.
This will break other build systems, so
they will need to remove the TCL_DBGX define
and replace it with a define for TCL_PIPE_DLL.
* win/makefile.vc: Ditto.
* win/tclWinPipe.c (TclpCreateProcess):
Remove PREFIX_IDENT and DEBUG_IDENT from
top of file. Use TCL_PIPE_DLL passed in
from build env instead of trying to construct
the dll name from already defined symbols.
This approach is more flexible and better
in the long run.

* win/tclWinPipe.c: from tcl.h -- they are not part of Tcl's
public interface. Put them in win/tclWinPipe.c where they are used.

TCL_DEBUG_IDENT, used only by TclpCreateProcess.
* unix/Makefile.in: Define TCL_DBGX.
* win/Makefile.in: Define TCL_DBGX.
* win/tclWinPipe.c (TclpCreateProcess):
Check that the Tcl pipe dll actually exists
in the Tcl bin directory and panic if it
is not found. Incorporate TCL_DBGX into
the Tcl pipe dll name. This fixes a really
mysterious error that would show up when
exec'ing a 16 bit application under Win95
or Win98 when Tcl was compiled with symbols.
The error seemed to indicate that the executable
could not be found, but it was actually the
Tcl pipe dll that could not be found.

* tests/winPipe.c:
* win/tclWinPipe.c (Tcl_WaitPid):
* win/tclWinTest.c: Gave Tcl_WaitPid the ability to return a
Win32 exception code translated into a posix style SIG*. This
allows [close] to report "CHILDKILLED" without the meaning
getting lost in a truncated exit code. In TclCleanupChildren(),
TclpGetPid() had to get moved to before Tcl_WaitPid() as the
the handle is removed from the list taking away the ability
to get the process id after the wait is done. This shouldn't
effect the unix implimentaion unless waitpid is called with
a pid of zero, meaning "any". I don't think it is..

exception, pass this notice on to the caller with a SIG* code
rather than truncating the exit code and missing the meaning.
This allows TclCleanupChildren() to report "CHILDKILLED".
This has a different behavior than unix in that closing the
read pipe to a process sends the SIGPIPE signal which is
returned as a SIGPIPE exit status. On windows, we send the
process a CTRL_BREAK_EVENT and get back a CONTROL_C_EXIT which
is documented to mean a SIGINT which seems wrong as a system,
but is the correct exit status.

NULL handle.
* win/tclWinPipe.c (PipeClose2Proc, TclpCreateProcess): Send a
real Win32 signal (CTRL_C_EVENT) when the read channel is brought
down to alert the child to close on its side. Start the process
with CREATE_NEW_PROCESS_GROUP to allow the ability to send these
signals. The following test case now brings down the child
without the use of an external [kill] command.

* win/tclWinPipe.c:
* win/tclWinSerial.c:
* win/tclWinSock.c:
* win/tclWinThrd.c:
* win/tclWinTime.c: General cleanup of all worker threads used
by the channel drivers. Eliminates the normal case where the
worker thread is terminated ('cept the winsock one). Instead,
use kernel events to signal a clean exit. Only when the worker
thread is blocked on an I/O call is the thread terminated.
Essentially, this makes all other channel worker threads behave
like the PipeReaderThread() function for it's cleaner exit
behavior. This appears to fix [Bug 597924] but needs 3rd party
confirmation to close the issue.

* win/tclWinPipe.c (BuildCommandLine): Fixed tcl Bug
[432499]. Part of the code used the non-absolute path to the
executable to determine quoting. This failed if the absolute
path cotained spaces, but the application name itselfl not. This
bug caused no trouble on Win NT 5, but does for other variants
in the Win* family. Report and fix due to Ken Poole
<kenpoole@users.sourceforge.net>.

Added more logic around the close-down of the pipe reader thread so
as to avoid, at all cost, a TerminateThread. Most cases with exec
are fixed, but I don't consider 2460 done yet. Closing down the
read side of a pipe before the child process, doesn't really fit
the windows model. [BUG: 2460]
