eCos/RedBoot for勤研ARM AnywhereII(4510) 含全部源代码

2004-04-15  Jonathan Larmour  <[e-mail]>

	* tests/fileio1.c: include stdio.h for rename() prototype.

2004-04-07  Andrew Lunn  <[e-mail]>

	* src/fd.cxx: Fix the assert just added. 0 is a valid fd.

2004-03-25  Sebastien Couret  <[e-mail]>

	* src/fd.cxx: Added CYG_ASSERT bound checking for file descriptor
	numbers (0<fd<CYGNUM_FILEIO_NFD).

2004-03-12  Jonathan Larmour  <[e-mail]>

	* src/fio.h: If no POSIX then CYG_FILEIO_DELIVER_SIGNALS
	and CYG_FILEIO_SIGMASK_SET call CYG_UNUSED_PARAM on their
	arguments to silence warnings.
	* src/file.cxx (rename): Use a throw specifier to match
	prototype.

2004-02-16  Andrew Lunn  <[e-mail]>

	* src/io.cxx (readwritev): For EWOULDBLOCK and EAGAIN return
	the number of bytes written if any have been written.

2004-01-07  Jonathan Larmour  <[e-mail]>

	* src/select.cxx: No need to make pselect() dependent on
	CYGPKG_POSIX - that would depend on the arguments. Assert instead,
	and more correctly make it contingent on CYGPKG_POSIX_SIGNALS.

	* src/fio.h: Separate out signal functionality into its own separate
	test.

2003-12-21  Sandeep Kumar <[e-mail]>

	* src/dir.cxx (readdir_r): Handle NULL dirp argument and return
	EBADF

2003-12-03  Dan Jakubiec  <[e-mail]>

	* src/select.cxx (pselect): Fixed the pselect() call to correctly
	handle NULL timeout arguments.  The previous implementation would
	cause a random timeout value to be used.

2003-11-28  David Woodhouse  <[e-mail]>

	* include/fileio.h, include/sockio.h, src/dir.cxx, src/fd.cxx,
	src/io.cxx: Don't include kernel headers if no kernel support.

2003-10-23  Savin Zlobec  <[e-mail]>

	* src/io.cxx: Added cyg_fs_fsetinfo and cyg_fs_fgetinfo functions.
	
	* src/file.cxx: Added cyg_fs_setinfo and cyg_fs_getinfo functions.
	
	* include/fileio.h: Added cyg_fs_fsetinfo, cyg_fs_fgetinfo,
	cyg_fs_setinfo and cyg_fs_getinfo function prototypes.

2003-10-16  Andrew Lunn  <[e-mail]>

	* src/socket.cxx (bind): Pass a copy of the socket address so the
	stack can modify it without changing the users copy. Bug found by
	[e-mail].

2003-10-06  Andrew Lunn  <[e-mail]>

	* src/fio.h (CYG_FILEIO_SIGMASK_SET): Fixed a compiler warning
	about an unused variable.

2003-09-22 Eric Doenges <[e-mail]>
	* src/devfs.cxx: prototype of dev_fo_select now matches
	implementation
	* include/fileio.h: changed definition of cyg_fileop_select to
	return a cyg_bool instead of int to match current implementations
	* src/misc.cxx: changed cyg_fileio_seltrue() to match prototype.

2003-07-11  Andrew Lunn  <[e-mail]>

	* src/socket.cxx (socket): If there are no network stacks configured
	return EAFNOSUPPORT when opening a socket.

2003-04-11  Jonathan Larmour  <[e-mail]>

	* src/socket.cxx: Give nstab_lock mutex a priority. Also it's
	local, so make static.
	Change nstab and nstab_end to cyg_nstab and cyg_nstab_end for
	cleaner namespace.
	* include/sockio.h: nstab -> cyg_nstab.
	* src/misc.cxx, src/dir.cxx, src/fio.h, src/file.cxx: Change
	fstab, fstab_end, mtab, mtab_end, cdir_dir, cdir_mtab_entry to
	have cyg_ prefix for cleaner namespace.

2003-03-20  Gary Thomas  <[e-mail]>

	* src/devfs.cxx: Remove unnecessary checks for -EAGAIN (should
	no longer happen in lower layers).

2003-03-08  Jonathan Larmour  <[e-mail]>

	* tests/pselect.c (pthread_entry1): Allow for infrequent but
	occasional off by one error due to race condition when
	signalling.

2003-02-24  Jonathan Larmour  <[e-mail]>

	* cdl/fileio.cdl: Add doc link.

2003-02-20  Bart Veer  <[e-mail]>

	* cdl/fileio.cdl: identify test binaries, not test sources

2003-01-30  Andrew Lunn  <[e-mail]>

	* cdl/fileio.cdl: Added interface CYGINT_IO_FILEIO_FS which any
	FS which FILEIO can use should implement. 

2003-01-23  Gary Thomas  <[e-mail]>

	* src/misc.cxx (cyg_mtab_lookup): Return an error if the current
	directory is not known - happens if no file systems are mounted.

2002-11-10  Nick Garnett  <[e-mail]>

	* src/fio.h: Added macros to deal with signal handling. These will
	call into the POSIX package if it is present, but are null if it
	is not.

	* src/select.cxx: Renamed original select() to cyg_pselect() and
	added select() and pselect() routine from POSIX-200X to call
	it. Reorganized code a little and added calls to macros to deal
	with signal delivery and detection.

	* cdl/fileio.cdl: 
	* tests/pselect.c: New test added to verify the signal masking and
	delivery behaviour of pselect().

	* tests/select.c: Fixed up some printfs to make it a little tidier.

2002-11-03  Gary Thomas  <[e-mail]>

	* src/io.cxx: 
	* cdl/fileio.cdl: Add readv()/writev() support.

2002-08-08  Nick Garnett  <[e-mail]>

	* src/select.cxx (select): Changed mechanism for calculating
	select timeout to avoid possible race conditions between this code
	and the timer DSR.

2002-05-29  Jesper Skov  <[e-mail]>

	* tests/fileio1.c: Removed strcat definition. Rely on string.h to
	provide it.

2002-05-28  Jonathan Larmour  <[e-mail]>

	* include/limits.h (NAME_MAX): Increase default to 64.
	* cdl/fileio.cdl: Set CYGBLD_ISO_NAME_MAX_HEADER.

2002-04-11  Nick Garnett  <[e-mail]>

	* doc/fileio.sgml: Added a section on writing a new
	filesystem. This probably still needs more work, but it's better
	than nothing.

2002-04-05  Nick Garnett  <[e-mail]>

	* src/devfs.cxx: Changed test for EAGAIN in dev_fo_read() and
	dev_fo_write() to negate value first. 

2002-03-07  Nick Garnett  <[e-mail]>

	* doc/fileio.sgml: Added this file to contain documentation on
	this package.

2002-02-04  Gary Thomas  <[e-mail]>

	* tests/socket.c (main): 
	* tests/select.c (main): sin_len field must be set.

2002-01-29  Jonathan Larmour  <[e-mail]>

	* cdl/fileio.cdl: Actually, don't bother to build testfs.c at all.

2002-01-29  Jesper Skov  <[e-mail]>

	* cdl/fileio.cdl: Added CYGPKG_FILEIO_BUILD_TESTS option and made
	building of testfs dependant on it.

2002-01-25  Jonathan Larmour  <[e-mail]>

	* include/inode.h: New API defining a common generic inode type.
	* src/inocache.cxx: Implement the inode cache functions.
	* cdl/fileio.cdl: (Configurably) build it.

2002-01-23  David Woodhouse  <[e-mail]>
2002-01-23  Jonathan Larmour  <[e-mail]>

	* cdl/fileio.cdl: Remove select compilation and support to new
	CYGFUN_IO_FILEIO_SELECT option conditional on the kernel
	Ditto for DEVS and CYGPKG_IO_FILEIO_DEVFS_SUPPORT.
	Make CYGPKG_IO_FILEIO_SOCKET_SUPPORT also conditional on kernel.
	* src/fio.h: Define FILEIO_MUTEX_LOCK() and FILEIO_MUTEX_UNLOCK()
	so that code doesn't need to care whether the kernel is included or
	not.
	* src/fd.cxx: Conditionalize mutex usage throughout on CYGPKG_KERNEL,
	and FILEIO_MUTEX_LOCK()/UNLOCK().
	* src/file.cxx: Ditto.

	(cyg_timestamp): Only use Cyg_Clock implementation if CYGPKG_KERNEL.

2002-01-23  Jonathan Larmour  <[e-mail]>

	* src/misc.cxx: Initialize fileio_initializer at prio CYG_INIT_IO_FS

	(selwait): ditto.
	* src/fd.cxx (fdlock): ditto

2002-01-04  Wade Jensen <[e-mail]>
2002-01-04  Jonathan Larmour  <[e-mail]>

	* src/socket.cxx (recvfrom): Set msg.msg_namelen correctly for

	tracing macros.
	Reported by Richard Panton.

2001-06-11  Jonathan Larmour  <[e-mail]>

	* src/socket.cxx (cyg_sock_unlock): Fix cyg_file_lock->cyg_file_unlock
	thinko.

	Added call to init_all_network_interfaces().

2000-12-15  Nick Garnett  <[e-mail]>

	* src/misc.cxx: Fixed some bugs in initialization of timestamp
	function when Wallclock and POSIX packages are absent.

2000-11-01  Jonathan Larmour  <[e-mail]>

	* src/io.cxx (readwrite): Ensure we call FILEIO_RETURN_VALUE() to
	get correct cleanup
	(fpathconf): Ditto
	(lseek): Ditto

	* src/file.cxx (open): If applicable, refer to stdin, stdout and stderr
	here to ensure they are pulled in, in case selective linking would
	otherwise eliminate them. This is to ensure they get allocated to
	fd's 0, 1 and 2.

2000-10-13  Nick Garnett  <[e-mail]>

	* src/io.cxx (readwrite): Merged both read() and write() functions
	into this single common routine.  

	* include/fileio.h: Introduced a common typedef for both read and
	write operations.

	* doc/fileio.txt: Added some text about getcwd() and tidied up
	some other parts.

2000-10-05  Nick Garnett  <[e-mail]>

	* src/file.cxx: Added support for getcwd(). There are three
	mechanisms provided here. The first is to use the FS_INFO_GETCWD
	key on the filesystem to use any support it has for this. If that
	fails it falls back on one of the two other mechanisms. If
	CYGPKG_IO_FILEIO_TRACK_CWD is set then the current directory is
	tracked textually in chdir() and the result of that is reported in
	getcwd(). Otherwise an attempt is made to traverse the directory
	tree to its root using ".." entries. This last option is
	complicated and expensive, so the other two mechanisms are to be
	preferred if possible.

	* include/fileio.h: Added FS_INFO_GETCWD getinfo option and a
	matching struct cyg_getcwd_info. These are used to access getcwd()
	support in a filesystem.

	* src/fio.h: Added initial support for POSIX API function entry
	and return. 

	* cdl/fileio.cdl: Added CYGPKG_IO_FILEIO_TRACK_CWD option to
	enable current directory tracking.

2000-09-28  Nick Garnett  <[e-mail]>

	* src/select.cxx (cyg_selwakeup):
	Removed test for whether the waiting thread is actually waiting
	for this event. This lead to a race condition when the thread is
