* sigproc.cc (checkstate): Make regparm.
(getevent): Change parameters in declaration, rename from getsem, make regparm.
(sig_send): Recognize that nosync is now an event. Remove some old cruft from
previous interrupt anywhere signal handler.
(getevent): Change parameters in definition, rename from getsem. Allocate
event rather than semaphore.
(wait_sig): Treat sigcatch_nosync as an event.

properly restored for a nested signal.

* cygthread.h (cygthread::main_thread_id): Make public.
* exceptions.cc (setup_handler): Remove unneeded priority stuff. Rename label
to reflect what it does. Add debugging for idiotic Windows NT problem. Change
debugging output to include signal number.
* miscfuncs.cc (low_priority_sleep): If available, use SwitchToThread function
to give time slice to other threads.
* wincap.cc: Properly define have_switch_to_thread throughout.
* wincap.h (wincap::switch_to_thread): New element.

and issue a warning if DEBUGGING and excessive.
(WFSO): When debugging and infinite timeout, loop.
|

also when compiling newlib.
|

* Makefile.in (LIBSERVER): Define and use.
* configure.in: Set LIBSERVER as appropriate.
* environ.cc: Rename allow_daemon to allow_server. Only recognize when
USE_SERVER is defined.

|
|
(CYGHEAPSIZE): Add another 64K.
* mmap.cc: Use cmalloc, ccalloc and crealloc with HEAP_MMAP type throughout.
|
|
* heap.cc (heap_init): Save pointer to end of heap reserved memory.
(sbrk): Don't attempt to commit memory beyond end of heap reserved memory.
Attempt to honor comment and reserve commitbytes if heapchunk fails.

* sigproc.cc (wait_sig): Keep looping if there are more signals to consider and
we are flushing signals.
(sig_send): Put nonsync signals in the correct bucket.

__SIGFLUSH. Christopher Faylor <cgf@redhat.com>
* exceptions.cc (_sigreturn): Handle nested signals without growing the stack.
|
|
* sigproc.cc (pending_signals): Make static.
(wait_sig): Use defined values rather than integers for rc. Never scan both
todo arrays as this could cause hangs if signals arrive from two different
sources. Rename saw_pending_signals to saw_failed_interrupt. Exit loop when
signal found. Enter low-priority sleep, if necessary, after finished
signalling completion. Set pending_signals when blocked
(from Pierre Humblet).

* sigproc.cc (sigpending): To here.
(getlocal_sigtodo): Return process-local signal array.
(sigpending): Accommodate new process-local signal array.
(sig_send): Ditto.
(sig_set_pending): Ditto.
(wait_sig): Ditto.

* exceptions.cc (setup_handler): Move non-interruptible condition handling
(back) to wait_sig (as suggested by Pierre Humblet).
(set_process_mask): Don't worry about calling sig_dispatch_pending from
sigthread since it is detected in the function anyway.
(sig_handle): Eliminate thisproc arg. Don't call sig_dispatch_pending on
SIGCONT since that should happen automatically.
* sigproc.cc (sig_dispatch_pending): Eliminate justwake argument. Just return
when called from sigthread.
(wait_sig): Change some variables to bool. Change inner while to an if. Move
uninterruptible signal handling here.
(sigproc_terminate): Don't call sig_dispatch_pending. Just increment semaphore
on exit.
* speclib: Use slightly different (but still flawed) method for determining
symbols to extract from libraries.

(umount): Add null/empty check for input parameters.

map length.

a "." and a FIXME comment.

* syscalls.cc: Add defines to avoid declaration issues when
renaming cygwin_lstat back to lstat.
(lstat): Reverted name change from cygwin_lstat.
|

free() is called.
|
|
* speclib: Rework to extract everything from libcygwin.a rather than building
things from existing object files.
|
|
DRIVE_REMOVABLE.
* fhandler.cc (fhandler_base::lseek): Be more paranoid when constructing
offsets from 64 bit value.
* syscalls.cc (logout): Avoid temp buffer memcpy since new scheme does not
require it.
(utmp_data): Rework as a macro which returns a pointer into a buffer.
(getutent): Use new buffer allocation mechanism to grab a utmp buffer.
(getutid): Ditto.
(pututline): Ditto.

end of directory condition is encountered as per SUSv2.
* fhandler_proc.cc (fhandler_proc::readdir): Ditto.

* fhandler_tty.cc (fhandler_tty_slave::open): Adjust console open handle
counter regardless of whether this is a pty or tty.
(fhandler_tty_slave::open): Ditto.
(fhandler_tty_slave::dup): Ditto.
(fhandler_tty_common::set_close_on_exec): Ditto.
(fhandler_tty_master::init_console): Decrement console open handle counter
after init since it will now be handled by all tty open.
