2003-02-24  Jonathan Larmour  <jifl@eCosCentric.com>

        * cdl/fileio.cdl: Add doc link.

2003-02-20  Bart Veer  <bartv@ecoscentric.com>

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

2003-01-30  Andrew Lunn  <andrew.lunn@ascom.ch>

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

2003-01-23  Gary Thomas  <gary@mlbassoc.com>

        * 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  <nickg@ecoscentric.com>

        * 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  <gthomas@ecoscentric.com>

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

2002-08-08  Nick Garnett  <nickg@calivar.demon.co.uk>

        * 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  <jskov@redhat.com>

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

2002-05-28  Jonathan Larmour  <jlarmour@redhat.com>

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

2002-04-11  Nick Garnett  <nickg@redhat.com>

        * 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  <nickg@redhat.com>

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

2002-03-07  Nick Garnett  <nickg@redhat.com>

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

2002-02-04  Gary Thomas  <gthomas@redhat.com>

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

2002-01-29  Jonathan Larmour  <jlarmour@redhat.com>

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

2002-01-29  Jesper Skov  <jskov@redhat.com>

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

2002-01-25  Jonathan Larmour  <jlarmour@redhat.com>

        * 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  <dwmw2@redhat.com>
2002-01-23  Jonathan Larmour  <jlarmour@redhat.com>

        * 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  <jlarmour@redhat.com>

        * 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/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 <Wade_Jensen@inter-tel.com>
2002-01-04  Jonathan Larmour  <jlarmour@redhat.com>

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

2001-06-14  Jonathan Larmour  <jlarmour@redhat.com>

        * src/fio.h (FILEIO_ENTRY): Don't use CYG_MACRO_START/END around
        tracing macros.
        Reported by Richard Panton.

2001-06-11  Jonathan Larmour  <jlarmour@redhat.com>

        thinko.

2001-03-15  Gary Thomas  <gthomas@redhat.com>

        * src/file.cxx (open): Check for required/valid open mode.

2001-03-14  Jonathan Larmour  <jlarmour@redhat.com>

        * src/misc.cxx (cyg_mtab_lookup): check valid mtab entry
        (umount): ditto.

2001-03-14   Martin van Veen  <martin_van_veen@yahoo.com>

        * src/misc.cxx (mount): Return error if mount fails.

2001-03-12  Gary Thomas  <gthomas@redhat.com>

        * src/misc.cxx (mount): Do implicit 'chdir()' in the
        absence of any statically mounted file systems.
        (cyg_fs_lock, cyg_fs_unlock): Add assertions.

        * src/file.cxx (LOCK_FS):

2001-01-05  Nick Garnett  <nickg@cygnus.co.uk>

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

2000-12-15  Nick Garnett  <nickg@cygnus.co.uk>

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

2000-11-01  Jonathan Larmour  <jlarmour@redhat.com>

        * 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  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <jlarmour@redhat.com>

        * src/select.cxx: Apply constructor prioritization to mutexes and
        condition variables
        * src/fd.cxx: Ditto

2000-09-11  Jonathan Larmour  <jlarmour@redhat.com>

        * 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  <nickg@cygnus.co.uk>

        * include/fileio.h:
        Removed spaces from arguments to CYG_HAL_TABLE_ENTRY().

2000-09-04  Jonathan Larmour  <jlarmour@redhat.com>

        * 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  <nickg@cygnus.co.uk>

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

2000-08-22  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * doc/fileio.txt: Add Nick's text description of plug-in filesystems
        and sockets here for now.

2000-08-18  Nick Garnett  <nickg@cygnus.co.uk>

        * 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  <jlarmour@redhat.co.uk>

        * 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  <jlarmour@redhat.co.uk>

        * 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  <nickg@cygnus.co.uk>

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

2000-07-27  Nick Garnett  <nickg@cygnus.co.uk>

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

2000-07-25  Jonathan Larmour  <jlarmour@redhat.co.uk>

        * tests/select.c (main): Wrap call to init_all_network_interfaces()
        in #ifdef TEST_NET

2000-07-25  Nick Garnett  <nickg@cygnus.co.uk>

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

2000-07-21  Nick Garnett  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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/fd.cxx: 
        * src/io.cxx: 
        * src/devfs.cxx: 
        Tidied up and sorted out locking protocols and synchronization
        mechanisms.

2000-06-09  Nick Garnett  <nickg@cygnus.co.uk>

        * 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  <nickg@cygnus.co.uk>

        * 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.

        * 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.
