* fork.cc (fork_copy): Cosmetic change.
2005-09-15 Christopher Faylor <cgf@timesys.com>

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.
2005-09-14 Christopher Faylor <cgf@timesys.com>
* spawn.cc (av::fixup): Avoid breaking out of the wrong "loop".

2005-01-22 Christopher Faylor <cgf@timesys.com>
* spawn.cc (spawn_guts): Perform same "cd" as in pinfo::exit below to
make sure that a stub process does not keep the current working
directory busy after the "execed" process has exited.
2005-01-22 Christopher Faylor <cgf@timesys.com>
* pinfo.cc (pinfo::init): Move everything but the MapViewOfFileEx out
of the loop since trying multiple times to call CreateFileMapping
doesn't make much sense. Try to structure the loop a little better so
that exiting with a break does the right thing.
(pinfo::release): Release shared memory area if it exists and close
handle if it exists.
2005-01-22 Christopher Faylor <cgf@timesys.com>
* pinfo.cc (pinfo::maybe_set_exit_code_from_windows): Make sure that
process has exited before getting an error code.

that process does not keep the current working directory busy while it
is in the process of really exiting.

an ITIMIDLIST in the file.
2005-01-16 Christopher Faylor <cgf@timesys.com>
* pinfo.h (maybe_set_exit_code_from_windows): Renamed from
set_exit_state.
* pinfo.cc (pinfo::exit): Use renamed function.

(remove_proc): Wait for waiter to finish copying pinfo element before
moving it (an actual wait should be an extremely rare event).

been set. Set flag when exitcode has been established. Don't set
PID_STATE here.
(pinfo::init): Remove exitcode initialization.
(pinfo::exit): Reflect change in EXITCODE_* naming. Set flag when
exitcode has been established. Reflect change in arguments to
set_process_state.
(proc_waiter): Reflect change in arguments to set_process_state. Set
process_state here and only here.

2005-01-15 Christopher Faylor <cgf@timesys.com>

SETACL if no acls are available.

name in case of device argument.
2005-01-13 Corinna Vinschen <corinna@vinschen.de>
* fhandler_serial.cc (fhandler_serial::dup): Call overlapped_setup
for child, not for parent.
2005-01-13 Christopher Faylor <cgf@timesys.com>
* init.cc (dll_entry): Nuke attempt to set exit code since parent will
use windows exit code if needed.
* pinfo.cc (pinfo::exit): Move release() here to minimize pid creation
race (suggested by Pierre Humblet).
2005-01-12 Christopher Faylor <cgf@timesys.com>
Reorganize header file inclusion throughout so that cygerrno.h comes
first.
* fhandler.h (select_record::thread_errno): Save any encountered errno
here.
(select_record::set_select_errno): New function.

(_pinfo::dup_proc_pipe): Close handle when there is no parent process
around to care about the exit value.

make sure that myself is still mapped in parent.
(do_exit): Reflect movement to pinfo::exit.
(__api_fatal): Ditto.
* exceptions.cc (signal_exit): Ditto.
* errno.cc (errmap): Map PROC_NOT_FOUND.
* init.cc (dll_entry): Release myself before exiting.
* sigproc.cc (proc_can_be_signalled): Set errno appropriately.

-- it is not an error.

in proc_waiter, if necessary.
* spawn.cc (spawn_guts): Delay "wait_for_myself" logic until later.

output to avoid SEGV when strace'ing.

2005-01-01 Christopher Faylor <cgf@timesys.com>
