SIGBUS error. Differ between unmapped memory (SEGV_MAPERR) and access
violation (SEGV_ACCERR) in case of STATUS_ACCESS_VIOLATION. Write
kernel log message in case of uncatched STATUS_ACCESS_VIOLATION.

support.

will theoretically cause blocking if there is nothing reading on the
pipe. Wait for sigCONT at end of loop when we have a __SIGHOLD.

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.

2005-09-21 Christopher Faylor <cgf@timesys.com>

* fork.cc (fork_copy): Cosmetic change.
2005-09-15 Christopher Faylor <cgf@timesys.com>
* 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.
2005-09-14 Christopher Faylor <cgf@timesys.com>
* spawn.cc (av::fixup): Avoid breaking out of the wrong "loop".
2005-09-14 Christopher Faylor <cgf@timesys.com>

proc_can_be_signalled for myself since the criteria is now different
for sending signals to myself.

signal loop when __SIGEXIT is received. Wait for main thread to exit
and use its exit status to actually exit process.

default nice value according to current Win32 priority class.
* pinfo.h (class _pinfo): Add nice member.
* syscalls.cc (setpriority): New function, only implementing
PRIO_PROCESS for now.

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.

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.

(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.

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

name in case of device argument.

* 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.

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.

output to avoid SEGV when strace'ing.

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