* 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.
* 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).
* 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.
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_process (fhandler_process::readdir): Ditto.
* fhandler_registry (fhandler_registry::readdir): Ditto.
is a tty associated with the process. Send SIGHUP on CTRL_LOGOFF_EVENT.
* 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.
* syscalls.cc (setsid): Rework debugging output slightly.
value for tokens.
* syscalls.cc (seteuid32): Ditto. Set new_token to process token if
process token is suitable.
* uinfo.cc (uinfo_init): Initialize tokens in cygheap user info
to INVALID_HANDLE_VALUE.
* cygheap.h (enum impersonation): Delete.
(cygheap_user::impersonation_state): Delete.
(cygheap_user::current_token): New.
(cygheap_user::issetuid): Modify to use current_token.
(cygheap_user::token): Ditto.
(cygheap_user::deimpersonate): Ditto.
(cygheap_user::reimpersonate): Ditto.
(cygheap_user::has_impersonation_tokens): Ditto.
(cygheap_user::close_impersonation_tokens): Ditto.
* security.cc (cygwin_set_impersonation_token): Always set the token.
(verify_token): Change type of gsid to cygpsid.
(get_file_attribute): Use the effective ids.
* syscalls.cc (seteuid32): Modify to use cygheap_user::current_token.
* uinfo.cc (uinfo_init) Do not set cygheap->user.impersonation_state.
