Corinna Vinschen 636c94d853 * smallprint.cc (__small_vswprintf): Fix uninitialized usage of `w'.
Revamp advisory file locking to avoid cross reference pointers as well
	as to allow BSD flock semantics.  More agressively delete unused nodes
	and sync objects.
	* fhandler.h (fhandler_base::ino): Rename from namehash.  Fix comment.
	(fhandler_base::node): Remove.
	(fhandler_base::unique_id): Add.
	(fhandler_base::del_my_locks): New method.
	(get_ino): Rename from get_namehash.  Change usage throughout Cygwin.
	(get_unique_id): New method.
	* fhandler.cc (fhandler_base::close): Call own del_my_locks method.
	Fix comment.
	(fhandler_base::fhandler_base): Accommodate new and changed members.
	(fhandler_base::fixup_after_fork): Call del_my_locks.
	(fhandler_base::fixup_after_exec): Ditto for files with close-on-exec
	flag set.
	* fhandler_disk_file.cc (get_ino_by_handle): Rename from
	readdir_get_ino_by_handle.  Accommodate throughout.
	(fhandler_base::open_fs): Fill ino with inode number if FS has good
	inodes.  Allocate a LUID and store in unique_id to recognize file
	descriptors referencing the same file object.
	* flock.cc: Drop flock TODO comments.  Use explicit types __dev32_t
	and __ino64_t instead of dev_t and ino_t.
	(LOCK_OBJ_NAME_LEN): Change to reflect longer lf_id length.
	(get_obj_handle_count): New method.
	(lockf_t::lf_id): Change type to long long.
	(inode_t::get_lock_obj_handle_count): Drop in favor of static function
	get_obj_handle_count.
	(inode_t::del_locks): Remove.
	(inode_t::get): Add create_if_missing flag argument.
	(inode_t::del_my_locks): Reimplement to handle POSIX and BSD flock
	locks.  Return if node can be deleted or not.
	(inode_t::~inode_t): Ditto.  Close handles to i_dir and i_mtx.
	(fixup_lockf_after_fork): Remove.
	(fhandler_base::del_my_locks): New method.
	(fixup_lockf_after_exec): Check if node can be deleted.
	(inode_t::get): Only create node if create_if_missing is set.  Lock
	the returned node here before unlocking the node list.
	(inode_t::get_all_locks_list): Accommodate new lf_id length.
	(inode_t::create_lock_obj): Ditto.
	(lockf_t::open_lock_obj): Ditto.  Change return type to bool.  De-const.
	Set lf_obj instead of returning a handle.
	(lockf_t::del_lock_obj): Call SetEvent only if new incoming parameters
	allow it.  Explain how it's supposed to work.
	(fhandler_disk_file::lock): Only fetch file length in SEEK_END case.
	Use NtQueryInformationFile(FileStandardInformation) instead of
	calling fstat_by_handle.  Always unlock node before returning.
	Use fhandler's unique id to create lf_id for BSD flock locks.
	Rely on node lock from inode_t::get.  Call del_lock_obj on removed
	locks here to allow explicit unlocking.  Delete node if no lock exists
	on the file anymore.
	(lf_setlock): Get file handle as additional parameter.  Handle the fact
	that lf_getblock now always opens the attached event object.  Reactivate
	erroneously applied patch which deactivates setting thread priority.
	Additionally handle blocking on BSD flock locks.
	(lf_clearlock): Get file handle as additional parameter.
	(lf_getlock): Close event handle opened by lf_getblock.
	(lf_getblock): Open potentially blocking event object here and check
	its signal state if it's a BSD flock lock.
	(lf_wakelock): Get file handle as additional parameter.
	* fork.cc (frok::child): Drop call to fixup_lockf_after_fork.
	* ntdll.h (struct _EVENT_BASIC_INFORMATION): Define.
	(enum _EVENT_INFORMATION_CLASS): Define.
	(NtQueryEvent): Declare.

	* fhandler.h (fhandler_base::fs_flags): Remove.
	(fhandler_base::set_fs_flags): Remove.
	(fhandler_base::get_fs_flags): Remove.
	* fhandler.cc (fhandler_base::write): Check for sparse file using
	pc.fs_flags().
	* fhandler_disk_file.cc (fhandler_disk_file::ftruncate): Ditto.

	The return of the volume serial number in fs_info.
	* fhandler.h (get_dev): New method.
	* fhandler_disk_file.cc (fhandler_base::fstat_by_handle): Drop call to
	NtQueryVolumeInformationFile(FileFsVolumeInformation).  Just use
	get_dev() method.
	* fhandler_fifo.cc (fhandler_fifo::open) Use device ID and inode number
	to generate fifo name.
	* path.h (fs_info::sernum): New member.
	(fs_info::serial_number): New method.
	(path_conv::fs_serial_number): New method.
	* path.cc (fs_info::update): Fetch volume serial number and store in
	sernum.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
