2013-01-11  Corinna Vinschen  <corinna@vinschen.de>

	* syscalls.cc (rename): Drop handling paths > 32757 chars, emit EINVAL
	instead, thus simplifying code allocating and filling pfri.  Drop size
	and use constant expression in NtSetInformationFile call.  Add comments.

	* cygerrno.h: Fix copyright.
	* exceptions.cc: Drop comment explaining removed variable.

2013-01-09  Corinna Vinschen  <corinna@vinschen.de>

2013-01-07  Christopher Faylor  <me.cygwin2013@cgf.cx>

	* thread.cc (pthread_rwlock::lookup_reader): Remove parameter: always
	assume that we're looking for the current thread.
	(pthread_rwlock::tryrdlock): Eliminate self variable.  Accommodate
	change in lookup_reader().
	(pthread_rwlock::unlock): Ditto.
	(pthread_rwlock::rdlock): Ditto.  Move add_reader call after writer
	tests to more closely mimic old behavior.
	(pthread_rwlock::wrlock): Accommodate change in lookup_reader().
	* thread.h ((pthread_rwlock::lookup_reader): Eliminate argument.

2013-01-07  Christopher Faylor  <me.cygwin2013@cgf.cx>

	* thread.cc (pthread_rwlock::add_reader): Perform new operation here
	and return pointer to allocated RWLOCK_READER structure.
	(pthread_rwlock::rdlock): Reorganize to reflect new add_reader
	functionality.

	lookup_reader().

	constructor.
	(pthread_rwlock::add_reader): Reflect new functionality.

2013-01-03  Christopher Faylor  <me.cygwin2013@cgf.cx>

	* globals.cc (exit_states): Renumber so that ES_EXIT_STARTING is first,
	as intended.

	exit_state > ES_EXIT_STARTING.

2013-01-03  Christopher Faylor  <me.cygwin2013@cgf.cx>

	* sigproc.cc (exit_thread): Set thread signal mask so that no signals
	are sent to an exiting thread.

2013-01-02  Christopher Faylor  <me.cygwin2013@cgf.cx>

	* sigproc.cc (no_signals_available): Remove exit_state test since
	signals are available in a limited fashion when exiting.
	(sig_dispatch_pending): Ditto.
	(sig_send): Ditto.
	(exit_thread): Rearrange to avoid an unnecessary DuplicateProcess when
	exiting.
	(wait_sig): Allow special signals when exiting.

	cygwin_exception class.  Accommodate new variable names.
	(cygwin_exception::dumpstack): Ditto stackdump -> dumpstack.
	(exception::handle): Move andreas processing earlier.  Defer signal
	processing decisions to the signal thread where they belong.  Pass
	exception information to sig_send via new siginfo_t si_cyg field.
	(ctrl_c_handler): Wait for SIGHUP signal to be processed since it could
	cause a process exit and we don't want races with thread exit lock.
	(signal_exit): Move back here from sigproc.cc.  Modify arguments and
	remove from sigpacket class.  Decide when to dump core based on signal
	type.
	(sigpacket::process): Handle exiting signals in context of threads
	rather than in the signal thread.  Signal debugger on non-Windows
	signals.  Remove setup_signal_exit call.
	* sigproc.cc (no_signals_available): Remove argument.
	(signal_exit_code): Delete.
	(close_my_readsig): Ditto.

	no_signals_available argument.
	(wait_sig): Remove attempt to "go asynchronous" on process exit.
	Delete __SIGEXIT handling.  Don't ever exit.
	* sigproc.h: Remove __SIGEXIT from signal enum.  Renumber.
	* include/cygwin/signal.h (siginfo_t): Add si_cyg entry.
