* faq-what.xml: Reword "supported" FAQ.
Semi-reversion of always-exit-from-sigthread change of 2005-09-15.
* exceptions.cc (sigpacket::process): Eliminate return after call to reinstated
noreturn function.
(signal_exit): Allow function to exit when a captive process has been
terminated.
* pinfo.cc (pinfo::exit): Enter exit_lock here. Once again exit here under
control of exit_lock.
* sigproc.cc (sig_send): Don't wait for completion if process is exiting.
Remove special __SIGEXIT accommodations.
(wait_sig): Just exit the thread when a __SIGEXIT has been detected. Don't
exit the process.
* cygtls.h (struct _cygtls::thread_handle): Remove/revert.
* sigproc.h (struct sipacket::thread_handle): Put thread_handle here.
* sigproc.cc (sigproc_terminate): Move setting of thread_handle...
(sig_send): ...to here. Put it in packet being sent. Only close pack.wakeup
when we're waiting for completion.
(wait_sig): Use thread_handle directly from received packet.
* cygheap.cc (cygheap_fixup_in_child): It's not just for exec.
* cygtls.h (struct _cygtls::thread_handle): New field.
* dcrt0.cc (exit_lock): Remove declaration.
* winsup.h (exit_lock): Add declaration.
* exceptions.cc (sigpacket::process): Properly return after signal_exit.
* pinfo.cc (pinfo::exit): Only exit the process if _my_tls.thread_handle has
not been filled out -- which should be an impossible event.
* sigproc.cc (sigproc_terminate): Fillout _my_tls.thread_handle to provide
something for wait_sig to wait for. Use the siginfo_t version of sig_send and
fill out the tls argument with _my_tls.
(wait_sig): Wait for the thread specified in pack.tls or (for now) complain
bitterly if it doesn't exit.
* pinfo.cc (set_myself): Call strace.hello unconditionally when DEBUGGING.
(pinfo::init): Sleep and issue debugging output before looping when a
PID_EXITED is found.
* fhandler.h (fhandler_base::fstat_helper): Declare with additional
file attributes argument.
* fhandler_disk_file.cc (fhandler_base::fstat_by_handle): Use
file attributes evaluated from NtQueryFileInformation or
FileInformationByHandle in call to fstat_helper.
Set pc.fileattr from just evaluated file attributes here.
(fhandler_base::fstat_by_name): Use file attributes evaluated from
FindFileFirst or default attribute in call to fstat_helper.
Set pc.fileattr from just evaluated file attributes here.
(fhandler_base::fstat_helper): Use file attributes given as argument,
not file attributes stored in this fhandler, since this information
is potentially wrong. Add comment to explain this.
* path.h (has_attribute): New global inline function.
(path_conv::set_attributes): New method to change fileattr.
Align error message handling to mkpasswd's error messages throughout.
* mkgroup.c (print_win_error): Create macro calling ...
(_print_win_error): ... this function created from former
print_win_error. Move up in source.
(PDOMAIN_CONTROLLER_INFOW): Define return type of DcGetDcNameW.
(dsgetdcname): New function pointer for DcGetDcNameW.
(load_netapi): Get DcGetDcNameW address.
(main): If DcGetDcNameW is available, use it.
* mkpasswd.c (PDOMAIN_CONTROLLER_INFOW): Define return type of
DcGetDcNameW.
(dsgetdcname): New function pointer for DcGetDcNameW.
(load_netapi): Get DcGetDcNameW address.
(main): If DcGetDcNameW is available, use it. Rename local variable
domain_name_specified to domain_specified as in mkgroup.c.
* cygthread.cc (cygthread::operator new): Just use getenv() to look for
CYGWIN_FREERANGE_NOCHECK since the Windows environment may be truncated by
being previously execed.

2005-09-20 Jeff Johnston <jjohnstn@redhat.com>
* libc/include/stdint.h (__EXP): Rename to __STDINT_EXP
and do not #undef the macro after it is used. Fix typos.
Also change 64-bit constants to use the __have_long64 and
__have_longlong64 flags to determine if long or long long
constants should be used.
* libc/include/inttypes.h: Include stddef.h to get wchar_t
type defined.
* dcrt0.cc (do_exit): Only call sigproc_terminate from one location --
pinfo::exit.
* pinfo.cc (pinfo::exit): Move sigproc_terminate later so that signals can be
processed while waiting for hExeced child.
(pinfo::maybe_set_exit_code_from_windows): Set exit code from sigExeced if it
is non-zero. Set exit_state to ES_EXEC_EXIT prior to waiting for captive
process exit code.
* exceptions.cc (sigExeced): New global variable.
(signal_exit): Remove noreturn attribute from declaration.
(signal_exit): Just terminate captive process and return if hExeced on the
theory that the exit will be subsequently handled in the main thread.
* sigproc.cc (sigproc_terminate): Eliminate test for ES_SIGPROCTERMINATE and
use ES_FINAL instead.
(sig_send): Use no_signals_available instead of duplicate test.
* winsup.h (ES_EXEC_EXIT): New enum.
(ES_SIGPROCTERMINATE): Delete.
* sigproc.cc (talktome): Take siginfo_t argument. Don't scan all pids trying
to find one that's talking to me. Just use the pid from siginfo_t.

my_sendsig. Pass in an argument controlling when it is appropriate to test
EXITCODE_SET.
(proc_can_be_signalled): Remove checks for myself since this function is never
called in that context.
(sigproc_init): Pre-initialize my_sendsig to non-zero so that
proc_can_be_signalled will know that we expect to be signalable soon.
(sig_send): Change debugging output.
* sigproc.cc (no_signals_available): Return true if sending to self from the
signal thread.
(wait_sig): Correct so that WaitForSingleObject is called when hMainThread is
!= 0, rather than the reverse.
* cygheap.cc (cygheap_fixup_in_child): Clarify potential error message.
* fork.cc (fork_copy): Cosmetic change.
* sigproc.cc (wait_sig): Reorganize exit case so that ExitProcess is always
called, since that is the intent of sending a __SIGEXIT. Wait forever for main
thread to go away since, presumably, the main thread told us it was going away.

the signal thread.

* pinfo.cc (pinfo::exit): Exit the thread if we forcefully terminated the main
thread

was still needed for subsequent stuff. Call sigproc_terminate with new
exit_state value.
* pinfo.cc (pinfo::exit): Call sigproc_terminate with new exit_state value.

* dcrt0.cc (do_exit): Rely on sigproc_terminate to set exit_state
appropriately.
* pinfo.cc (pinfo::exit): Always call sigproc_terminate here. Rely on
sigproc_terminate to signal signal thread to handle eventual process exit.
* sigproc.cc (no_signals_available): Change criteria for determining if this
process can handle signals to itself.
(my_sendsig): New variable. Copy of my sendsig handle.
(proc_can_be_signalled): Don't send signals if exit code is set.
(sigproc_terminate): Use and set exit_state appropriately to determine when to
do anything. Send __SIGEXIT to self to control process exit.
(sig_send): Use my_sendsig for sending signals. Don't call
proc_can_be_signalled for myself since the criteria is now different for
sending signals to myself.
(wait_sig): Copy myself->sendsig to my_sendsig for future use. Exit signal
loop when __SIGEXIT is received. Wait for main thread to exit and use its exit
status to actually exit process.
* sigproc.h (__SIGEXIT): New enum.
* dcrt0.cc (alloc_stack): Eliminate superfluous "return;".

heap. Change fatal error to avoid confusion with cygheap.
* spawn.cc (linebuf::finish): New function.
(linebuf::add): Cosmetic change.
(spawn_guts): Only avoid building windows command line if the program being
executed was actually mounted with -X. Don't return E2BIG if we hit the 32K
size and we're executing a detected cygwin program. Just silently truncate the
windows command line, instead.
* fhandler_serial.cc (fhandler_serial::ioctl): Always return 0 for window size.
* termios.cc (tcgetattr): Clear out baud part of c_cflag since it is always
ignored.
