(call_handler): Eliminate inner for loop. Grab signal critical section lock
where appropriate.
* sigproc.cc (proc_subproc): Restore uid setting.
* sigproc.h (sigthread): Reinstitute sigthread lock as a critical section.
(sigframe): Grab the sigthread lock before clearing frame to avoid having the
signal thread use an invalid frame.
parent handle.
* dcrt0.cc (_dll_crt0): Close parent's parent handle when spawned or forked.
* debug.cc (add_handle): Correct erroneous reference to handle structure when
printing warning.
* exceptions.cc (interrupt_now): Always return 1.
(interrupt_on_return): Accept a sigthread argument. Check to see if this
argument has been trashed prior to setting up the stack return.
(call_handler): Add a loop around attempts to dispatch signals to detect case
where interrupt_on_return fails.
(_sigdelayed): Set up a temporary frame pointer prior to calling stuff that
could trigger an interrupt or the stack walking code will be very confused.
* fork.cc (fork_parent): Move a lot of the setup of the child process into
proc_subproc.
* spawn.cc (spawn_guts): Ditto. Use ppid_handle to contact logical parent when
reparenting.
* pinfo.h (_pinfo): Remember the logical handle of the parent process.
* sigproc.cc (proc_subproc): Record most stuff necessary for the _pinfo
structure that is inferrable from myself when adding children.
(wait_sig): Always set 'pending_signals' flag when about to kick off the signal
scanning loop. Reset it only if there are no pending signals.
(winpids::enumNT): New method renamed from EnumProcessesNT. Use add method to
add elements to the lists.
(winpids::enum9x): New method renamed from EnumProcesses9x. Use add method to
add elements to the lists.
(winpids::enum_init): Accept 'winpid' parameter to control whether to add all
windows pids to the list.
(winpids::release): New method.
* pinfo.h (winpids): Reflect above changes.
* signal.cc (kill_pgrp): Ditto.
* external.cc (fillout_pinfo): Ditto.
execed process to avoid a race.
* sigproc.cc (wait_subproc): Print more info when a WFSO error occurs.
* automode.c: New file.
* syscalls.cc (close_all_files): Streamline slightly.
* cygheap.cc (ccalloc): Clear *entire* allocated array.
(EnumProcesses9x): Rename from EnumProcessesW95. Change arguments to be more
useful for cygwin.
(winpids::init): Accomodate argument changes.
(enum_init): Ditto.
* pinfo.h (winpids): Make pidlist dynamically extendable by storing it as a
pointer and remembering the size.
* ntdll.h: Add extra definitions needed for EnumProcessesNT. Reformat via
'indent'.
(sigreturn): Construct pseudo-frame-pointer so that signal handler can figure
out where to put return address when signals are coming in quickly.
* path.cc (cwdstuff::get): Allow length 0 buffer length when buffer when NULL.
`fixup_after_fork'.
* fhandler_raw.cc (fhandler_dev_raw::fhandler_dev_raw): Add
`set_need_fixup_after_fork' call.
(fhandler_dev_raw::~fhandler_dev_raw): Revert to user space
allocation.
(fhandler_dev_raw::open): Ditto.
(fhandler_dev_raw::dup): Ditto. Reset buffer pointer.
(fhandler_dev_raw::fixup_after_fork): New function.
* fhandler_tape.cc (fhandler_dev_tape::open): Revert to user space
memory allocation.
(fhandler_dev_tape::ioctl): Ditto. Change behaviour on MTSETBLK when
new size is 1.
