        * cdl/fileio.cdl: Add doc link.

2003-02-20  Bart Veer  

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

2003-01-30  Andrew Lunn  

        * cdl/fileio.cdl: Added interface CYGINT_IO_FILEIO_FS which any

        FS which FILEIO can use should implement.

2003-01-23  Gary Thomas  

        * 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  

        * 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  

        * src/io.cxx:

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

2002-08-08  Nick Garnett

        select timeout to avoid possible race conditions between this code

        and the timer DSR.

2002-05-29  Jesper Skov  

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

        provide it.

2002-05-28  Jonathan Larmour  

        * include/limits.h (NAME_MAX): Increase default to 64.

2002-04-11  Nick Garnett  

        * 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  

        * src/devfs.cxx: Changed test for EAGAIN in dev_fo_read() and

        dev_fo_write() to negate value first.

2002-03-07  Nick Garnett  

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

        this package.

2002-02-04  Gary Thomas  

        * tests/socket.c (main):

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

2002-01-29  Jonathan Larmour  

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

2002-01-29  Jesper Skov  

        * cdl/fileio.cdl: Added CYGPKG_FILEIO_BUILD_TESTS option and made

        building of testfs dependant on it.

2002-01-25  Jonathan Larmour  

        * 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  

2002-01-23  Jonathan Larmour  

        * 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.

        * src/misc.cxx: Ditto.

        (cyg_timestamp): Only use Cyg_Clock implementation if CYGPKG_KERNEL.

2002-01-23  Jonathan Larmour  

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

        so it happens after the devices it depends on.

        * src/file.cxx (getcwd_lock): Ditto.

        * src/select.cxx (select_mutex): ditto.

        (selwait): ditto.

        * src/fd.cxx (fdlock): ditto

        (file_lock): ditto.

        * src/dir.cxx (readdir): Use FILEIO_RETURN_VALUE on exit.

        (readdir_r): Ditto.

        * src/devfs.cxx (dev_stat): Don't use handle for st_dev - it will

        probably be truncated.

2002-01-04  Wade Jensen 

2002-01-04  Jonathan Larmour  

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

        NULL fromlen.

        CYGPKG_POSIX_PTHREAD as in the POSIX package.

2001-07-26  Jonathan Larmour  

        * cdl/fileio.cdl: Implements select().

        * src/select.cxx: Include  from isoinfra.

2001-07-19  Jonathan Larmour  

        * src/devfs.cxx (dev_fo_read): Treat non-blocking reads returning

        EAGAIN correctly

        (dev_fo_write): Ditto for writes.

2001-06-14  Jonathan Larmour  

        * src/fio.h (FILEIO_ENTRY): Don't use CYG_MACRO_START/END around

        tracing macros.

        Reported by Richard Panton.

2001-06-11  Jonathan Larmour  

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

        thinko.

        absence of any statically mounted file systems.

        (cyg_fs_lock, cyg_fs_unlock): Add assertions.

        * src/file.cxx (LOCK_FS):

        * src/dir.cxx (LOCK_FS): Add assertions on 'mte'.

2001-01-05  Nick Garnett  

        * tests/socket.c (main):

        Added call to init_all_network_interfaces().

2000-12-15  Nick Garnett  

        * src/misc.cxx: Fixed some bugs in initialization of timestamp

        function when Wallclock and POSIX packages are absent.

2000-11-01  Jonathan Larmour  

        * 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  

        * 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  

        * 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  

        * 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

        still polling other objects but has already checked this

        event. Now all waiting selectors are woken up by each selectable

        event.

2000-09-18  Jonathan Larmour  

        * src/select.cxx: Apply constructor prioritization to mutexes and

        condition variables

        * src/fd.cxx: Ditto

2000-09-11  Jonathan Larmour  

        * tests/select.c: NA if no POSIX package

        * cdl/fileio.cdl: Set CYGBLD_ISO_OPEN_MAX_HEADER to this package's

        limits.h

        * include/limits.h: New file to define OPEN_MAX (and other things in

        future)

2000-09-08  Nick Garnett  

        * include/fileio.h:

        Removed spaces from arguments to CYG_HAL_TABLE_ENTRY().

2000-09-04  Jonathan Larmour  

        * include/sockio.h (struct cyg_nstab_entry): Apply CYG_HAL_TABLE_TYPE

        * include/fileio.h (struct cyg_mtab_entry): Ditto

        (FSTAB_ENTRY): Ditto

2000-08-31  Nick Garnett  

        * src/select.cxx (select): Added scheduler unlock in timeout

        return case.

2000-08-22  Jonathan Larmour  

        * doc/fileio.txt: Add Nick's text description of plug-in filesystems

        and sockets here for now.

2000-08-18  Nick Garnett  

        * include/fileio.h: Added CYG_FAPPEND flag for preservation in

        file object flags.

        Added prototype for cyg_timestamp().

        * src/misc.cxx: Fixed bug in cyg_mtab_lookup() when dealing with

        empty mount table entries.

        Added cyg_timestamp() to provide timestamp support to client

        filesystems.

2000-08-09  Jonathan Larmour  

        * src/misc.cxx: Don't define own strcmp() function (which had a bug

        anyway). Use string.h.

        * cdl/fileio.cdl: requires ISO C string functions

2000-08-01  Jonathan Larmour  

        * src/misc.cxx: Use correct initializer for mtab_extra

        * src/fio.h (FILEIO_RETURN_VOID): Surround in CYG_MACRO_START to

        prevent problems when used with one-line if.

        (FILEIO_RETURN_VALUE): Likewise

        * include/fileio.h: Make getinfo/setinfo take void *bufs, not char *

        for easier casting (and more correct)

        * tests/testfs.c: Likewise

        * src/devfs.cxx: Likewise.

        Also fix bug with Nick's change below that set non-blocking mode

        in all cases.

2000-07-31  Nick Garnett  

        * src/devfs.cxx (dev_open): Added support for O_NONBLOCK.

2000-07-27  Nick Garnett  

        * tests/select.c: Wrapped include of pkgconf/io_serial.h in

        #ifdef CYGPKG_IO_SERIAL.

2000-07-25  Jonathan Larmour  

        * tests/select.c (main): Wrap call to init_all_network_interfaces()

        in #ifdef TEST_NET

2000-07-25  Nick Garnett  

        * tests/select.c (main): Added call to

        init_all_network_interfaces().

2000-07-21  Nick Garnett  

        * include/fileio.h:

        * src/file.cxx:

        * src/devfs.cxx:

        * tests/testfs.c:

        Added support for link() API call. This was the only major file

        operation omitted.

2000-07-20  Nick Garnett  

        * include/fileio.h: Added some modes for fsync().

        * src/file.cxx: Added access() function.

        * src/io.cxx: Added fdatasync() and isatty().

        * src/devfs.cxx: Added fsync() support.

        * tests/fileio1.c: Added calls to access() to check (non-)existence

        of files where appropriate.

2000-07-13  Nick Garnett  

        * src/select.cxx (select): Fixed return value when timing out. Now

        returns zero and no error, it used to return -1 and ETIMEDOUT.

        * src/io.cxx: Fixed fsync() to match standard.

        * src/devfs.cxx:

        Added lseek() support - all devices are always at position

        zero. Added [f]stat() support - currently just fills in the stat

        buffer with some predefined values. When we have more

        sophisticated devices this may need to be improved.

        * tests/testfs.c (testfs_open): Added support for O_TRUNC open

        flag.

        * tests/stdio.c:

        * cdl/fileio.cdl:

        Added stdio.c to test C library IO integration. This does not test

        the C library functionality, just that it works with the fileio

        package in certain limited ways.

2000-06-30  Nick Garnett  

        * src/misc.cxx: Fixed definition of mtab_extra[] so that it gets

        emitted correctly into the object file.

        * tests/testfs.c:

        Added support for dynamic mount()/umount().

        Added testfs_dump() to report state of filesystem, and to do a

        little consistency checking.

        * tests/fileio1.c: Extended testing to mount() and maximum file

        sizes.

2000-06-28  Nick Garnett  

        * include/dirent.h: Added this file to contain directory support

        definitions.

        * include/fileio.h:

        Introduced separate typedefs for all operation functions.

        Added CYG_FDIR to mark directory streams.

        Added some default operation functions.

        * src/fio.h (FILEIO_RETURN_VOID): Added this macro.

        * src/dir.cxx: Added this file to contain directory listing API

        functions.

        * src/misc.cxx:

        Added default operation functions.

        * src/file.cxx:

        Fixed mkdir() to have correct prototype.

        Moved opendir() to dir.cxx.

        Added support in chdir() for deregistering the current directory.

        * cdl/fileio.cdl: Added dev.cxx to compile list. Added support for

        dirent.h implementation.

        * tests/testfs.c: Lots of changes towards a more complete

        implementation.

        * tests/select.c: Changed SHOW_RESULT() message a little. Fixed up

        some warnings when no testing is possible.

        * tests/fileio1.c:

        Largely rewritten to do more complete testing.

2000-06-19  Nick Garnett  

        * src/select.cxx: Added selwake_count variable to count select

        wakeups. This allows us to avoid sleeping when a selectee calls

        cyg_selwakeup() while we are still scanning the FD sets.

        * include/fileio.h:

        * include/sockio.h:

        * src/misc.cxx:

        * src/socket.cxx:

        Converted tables to new mechanism.

        * tests/select.c: Reduced buffer size to avoid buffer overflow in

        serial devices.

2000-06-15  Nick Garnett  

        * include/fileio.h:

        Added typedef for cyg_selinfo.

        Added umount to fstab entry structure.

        Added mount() and unmount() prototypes.

        Added const in various places.

        Changed some types from CYG_ADDRWORD to their ISO standard

        equivalents.

        Added si_thread field to cyg_selinfo structure, added

        cyg_selinit() prototype.

        * src/socket.cxx: Converted an errant LOCK_NS() into the

        UNLOCK_NS() it should be.

        * src/select.cxx:

        Added cyg_selinit() which must be called by all selectees at

        initialization to prepare a cyg_selinfo structure for use.

        Modified cyg_selwakeup() to minimize the number for actual wakeup

        operations it actually performs.

        * src/misc.cxx:

        Added mtab_extra[] to contain dynamic mount table entries,

        modified startup scan of mtab to cope with this.

        changed matchlen() to cope with "/" mountpoint, this function is

        rapidly ceasing to be the neat bit of code it started out as.

        Added implementations of mount() and umount().

        * src/devfs.cxx: Added dev_umount, various minor tweaks.

        * cdl/fileio.cdl: Added CYGNUM_FILEIO_MTAB_EXTRA to define how

        many extra mount table entries should exist for dynamic mounts.

        Added select.c to list of tests.

        * tests/select.c: Added this file to test select() functionality

        on both sockets and (serial) devices.

        * tests/socket.c: Tidied some compilation warnings.

        * tests/testfs.c: Added umount stub function.

        * src/fio.h:

        * tests/testfs.c:

        * src/socket.cxx:

        * src/misc.cxx:

        * src/file.cxx:

        * src/fd.cxx:

        * src/io.cxx:

        * src/devfs.cxx:

        Tidied up and sorted out locking protocols and synchronization

        mechanisms.

        * src/select.cxx:

        * src/devfs.cxx:

        * include/fileio.h:

        * tests/testfs.c:

        Added select() support.

        * src/socket.cxx: Fixed a resource management bug in accept().

        * tests/socket.c: Extended to test that all API calls work, at

        least minimally, as they should. Still some calls to add here.

2000-06-07  Nick Garnett  

        * tests/socket.c: Simple socket API test program. Needs much more

        work to give full coverage.

        * src/socket.cxx: Filled in some implementations. Changed some

        type specifications.

        * src/select.cxx: Added this file to contain select()

        implementation. At present it does nothing.

        * include/sockio.h:

        Added definition of socklen_t for use when the NET package is

        absent - just so this file compiles.

        Added macro to generate an nstab entry.

        Changed prototypes of socket operation ffunctions to better match

        both API definition and BSD stack implementation.

        * cdl/fileio.cdl: Added support for socket API. This is only

        active if the NET package is present.

        Added initial socket API test program.

2000-06-02  Nick Garnett  

        * src/socket.cxx:

        Added this file to implement socket interface. This is still a

        rough draft that has not yet been tested.

        * src/misc.cxx:

        * src/io.cxx:

        * src/fio.h: Various minor changes and bug fixes.

        * src/file.cxx: Various bug fixes. Added pathconf().

        * src/fd.cxx: Various changes and bug fixes, mostly in the

        handling of the locking mechanisms.

        * src/devfs.cxx: Added this filesystem to interface to the device

        IO subsystem. Not yet tested.

        * include/sockio.h: Various minor changes prompted by

        implementation.

        * include/fileio.h:

        Added macros to instantiate filesystem and mount table entries.

        Added mode mask for setting up f_flags.

        Changed file object types, added device type.

        * cdl/fileio.cdl:

        Added some extra files to compile. Some now go in libextras.

        Added table maxima for fstab, mtab and nstab.

        Added tests.

        * tests/fileio1.c: Added this simple test for the fileio

        infrastructure.

        * tests/testfs.c:

        Created this simple ROM filesystem to test out the fileio

        infrastructure. This is not really usable for anything other than

        this, and should not be used in "production" systems. Hence its

        presence in tests rather than src.

        At present this only has support for open(), close(), read(),

        write(), lseek() and unlink(). Other parts will be implemented as

        and when required.

        * src/fio.h:

        * src/file.cxx:

        * src/io.cxx:

        * src/misc.cxx:

        Roughed out most of the file IO infrastructure. While this code

        compiles, none of it has actually been executed yet. A lot of this

        was cut-and-paste-and-edit, so some minor blemishes are to be

        expected.

        * src/fd.cxx: Several modifications in response to implementing

        rest of infrastructure. Added dup() and dup2() API routines.

        * include/fileio.h: Many changes and tidies prompted by

        infrastructure implementation.

        * cdl/fileio.cdl: Added "implements" directives for isoinfra

        interfaces. Extended compile to new files.

        * include/fileio.h:

        * include/sockio.h:

        * src/fd.cxx:

        * cdl/fileio.cdl:

        Created these files as a start at defining the file IO package.

        There is still a lot to do here, so expect radical changes to all

        of these files in the near future.
