      Fix for writes spanning a fragment · 91e05a7e
      Robert Sprowson authored
      FileCore80.s: Revision 4.14 accidentally lost the calculation at line 1324 after FragLeft, so when a large write occurred it didn't get split either side of the fragment, and then an impossibly long scatter list would be emitted.
      Tidied some DebugG debug messages.

      Fix for mistargetted write with a file size > 2G when a background scatter list straddles a fragment
      When large transfers are being buffered to be written in the background they are attached to the Fcb without considering how the underlying disc fragments are lined up.
      When the background process grabs a handful of buffers to build into a scatter list to pass to the low level DiscOp it picks the head of the list and goes forward (SkipWriteBehind) to the fragment end and back (BackwardSkipWriteBehind).
      However, BackwardsSkipWriteBehind uses DefFileFrag which substitutes a default offset of 0, and the signed compare resulted in this being left as the believed start of fragment.
      In turn, far too many buffers got associated with the fragment, and written to the wrong place on the disc.
      In general this doesn't occur, but if the group of buffers happens to straddle a fragment, and that group of buffers is > 2G, the signed compare would trip up.
      As fsbash uses the same random number seed this conspired that testing the same drive twice (with and without background transfers enabled) would appear to pass the integrity check step. A new harddisc was used to show this up.
      FileCore80.s: Recoded the compare to be in sectors, so 4G files aren't top bit set, but shared files not at the fragment start still are.
      Docs/AdfsBuffers: Added some notes before I forget what I just wrote meant.

      Extend upper permissable file size to 4GB-1 · 47fd7e2c
      Robert Sprowson authored
      Tested for ~200,000 cycles in various configurations with FSBash, with no integrity problems, nor bad maps. However, background transfers (currently only used by ADFS) is still being endurance tested, hence is currently disabled.
      Users should note that they can create big files without needing to reformat their drives, however if reverting to an older copy of FileCore the files must not be opened, loaded, or deleted (it's fine to view the directory, just don't expect old FileCore to know how to parse such long fragment runs).
      Current versions of DiscKnight (1.49) do not understand long fragment runs.
      * Reviewed and expunged various signed comparisons of file pointers in the existing tests
      * Added new tests for big files which attempt to aggrevate all the usual problems passing over and up to important boundaries
      * Makefile recreated from fragments
      * Some compiler warning squashed
      * Some notes added for big file support
      Commands: swapped to using Command macro
      HelpText: labels renamed to help Command macro
      GenSWIs: text table name for SectorDiscOp ammended to match exported header and corresponding secondary module names (ADFS_SectorDiscOp et al). The usefulness of calling the base instantiation of FileCore_SectorDiscOp is minimal, especially from BASIC.
      Messages: message for attempting to check an old map disc made less terse
      hdr/FileCore: typo

      Revise exports in "hdr.FileCore". · 9ae2d7ca
      Robert Sprowson authored
      Now, for each SWI call there is a definition of any pertinent structures it asks for and definitions of any bitfields within those flags. This avoids the need for clients to endlessly redefine these locally (in practice it looks like sections of FileCore were simply copy and pasted into clients RAMFS/SCSIFS/ADFS). Delete private definitions.
      This binary was carefully checked to be identical since so many locations were changed.
      Then, the following additional changes:
      * InitDieSvc line 74, the floppy config is extracted using a mask and shift rather than reaching up the stack
      * Identify lin 1254, the superfluous instruction marked as such deleted
      * FileCore15 line 762 recoded the check for background op to not need the bit number defined any more
      * FileCore00 moved the label 'anull' to be word aligned guaranteed
      The duff pointer marker ('nowt' = &40000000) is no longer used to mark territory translation tables as invalid as that address is now quite reasonable. -1 is used instead.

      * Various 32-bit compatibility fixes. · ac186d66
      Kevin Bracey authored
      * Can use HAL for FIQ+timer manipulations.
      * FileCore_DiscOp64 added (as user API - currently just converted to the
        standard byte or sector DiscOp call to the underlying module). See
        Doc.32bitAPIs for full details.
      * New error-passing scheme to modules added (for full 32-bit addressing).
      * FileCore_Features added (indicates new error scheme).
      * OS_FSControl 49 (read 32-bit free space) now reports sensible clamped
        values for large discs, rather than values modulo 2^32.
      * Accessing the end of files near 2GB in size could cause lock-ups in
        background transfers.
      * F(+) and G(+) disc formats adjusted to have a little more skew to
        help the rather poor Iyonix floppy controller.

      Merge of Ursula branch to the trunk. · 4abef130
      Stewart Brodie authored
        This module represents the latest version of FileCore incorporating
          both the Ursula changes and the ROL changes as we have them to date.
        Changes from ROL-FileCore-3_21 are basically the stripping of trailling
          spaces and the change of Version to Module_Version in the conditionals.
          No other changes.
        ROL branch tagged ROL_merge
        Ursula branch tagged Ursula_merge.
        Untested, but essentially the same as ROL-FileCore-3_21, so no problems
