      Fix delivery of extended scroll requests · b752d15a
      Jeffrey Lee authored
      Extended scroll requests and regular scroll requests share the same
      reason code, but are different sizes. Update calcmessagesize to
      calculate the size of extended scroll messages correctly, so that the
      icon number won't get chopped off when the message is being passed to
      the target task.

      Fix issue where dragging text from icon caused a crash in foreground task · 1475387a
      Andy Vawer authored
      When releasing claim, use of stale register meant that the foreground task wasn't correctly bouncing Message_Dragging when the pointer moved out of range. Also added a sanity check in get_selected_text so that if for some reason the selection window disappears mid action it will be caught and not cause a crash.

      Add Wimp_Extend 15, "read slot size" · 4610877c
      Jeffrey Lee authored
      Wimp_Extend 15 is equivalent to Wimp_SlotSize,-1,-1, with the exception
      that the sizes returned in R0-R2 are now measured in pages instead of
      bytes. This allows code to accurately read the amount of free memory on
      machines with >2GB of RAM, and provides some future-proofing should we
      ever wish to support tasks with >2GB of RAM (e.g. via a future
      super-jumbo wimpslot, or more likely via sparse/PMP wimpslots, where
      the physical size is larger than the logical size).
      
      Currently there's no need to provide a page-based call to set the slot
      size (~2GB is fine for the forseeable future), so this call only
      focuses on reading the sizes.

        In CBTask.s
          A drag to writeable with invalid (eg.rejection due to validation string mismatch or overlong insert) caused ghost caret to be left behind and still deletes the source text.

      Fix for bad error pointer deleting non existent sprite · 431bcb1a
      Robert Sprowson authored
      Doing *WimpKillSprite _not_there_  had the following behaviour
      
      Priority   | Sprite exists  Sprite doesn't  Sprite is ROM
      Lo then Hi | Deletes        Bad error ptr   Silence
      Hi then Lo | Deletes        Silence         Silence
      
      The bad error pointer was caused by an early return if the high priority pool is the ROM sprites (because the earlier failure to find it in the low priority pools set V, and the early return used TEQ, so the error pointer in R0 was the SpriteOp reason code).
      Proceed to try to look up the sprite, even if there's no hope of deleting it, in order to get a valid error message.

      Fix crashes when a Wimp_Poll post-filter causes the Wimp to postpone switching to a VFP-enabled task
      
      Detail:
        s/Wimp07 - In ExitPoll, swap around the order of restoring the FP context and calling the poll post-filter so that the FP context is restored after the post-poll filter has been invoked. Previously, the VFP(+FPA) context would be restored, then the post-poll filter would be invoked. If the post-poll filter was claimed, the Wimp would then scan the pollwords again and most likely decide to switch to a different task. The appslot will then be switched over, and ExitPoll will be invoked again, attempting to restore the VFP/FPA context for that task - potentially causing a crash or other bad things because the VFP context used by the original choice of task is no longer paged in. For FPA this was never really a problem, since the context is stored in the RMA rather than being potentially stored in appspace.

      Recache currentmode at the right time · 121acd27
      ROOL authored
      Detail:
        Modification to make the Wimp reread 'currentmode' by calling OS_ReadSysInfo 1 in the following circumstances
        1. On module init (accounts for being softloaded off disc)
        2. At Service_Reset (accounts for any graphics driver starting after it in ROM module order)
        3. When Service_ModeFileChange (new, this catches the new mode selected by an MDF or EDID during !Boot)
        Commoned up these 3 cases into 1 function.
        This restores the design intent that to get the monitor's native resolution it is *not* required to configure the MonitorType=EDID, indeed doing so wouldn't have helped loading EDID off disc if the monitor's data is found to be incorrect and needing overriding.

      Detail:
        This restores support for Wimp_ClaimFreeMemory, via having the Wimp manage a small-ish (4MB) DA that is used to satisfy Wimp_ClaimFreeMemory requests. The Wimp will only ever grow the DA, but the DA is shrinkable, so the system should shrink it as necessary should the free pool run too low.
        Options/s/!Default, Options/s/32, Options/s/Ursula - Add DynamicAreaWCF option to control support for the Wimp_ClaimFreeMemory DA. Enable the option for any builds of the module destined for RISC OS 5.

      Width counting of menus in the system font would continue until a control terminator was found, however in the case of a non indirected menu entry of exactly 12 characters there is no terminator, so the menu would be too wide (by however many non terminator bytes happened to follow the menu definition in memory).

      Fix for missing window backgrounds/scroll bars when tiled sprite op not supported · f0e0f3ad
      Robert Sprowson authored
      For the backgrounds, the code was switched with 'standalone' however the Wimp actively wipes SA_FLAGS in its makefile so the standalone switch is always false during the install phase of a disc build. Also, the standalone switch is used to include resources which are ordinarily handled by the boot sequence prefixing the WindowManager$Path rather than using ResourceFS.
      For the scroll bars, the decision to plot manually was being made by looking at the V flag on return from Tool_SpriteOp, except that that function uses EntryS/EXITS so the caller can't see the return flags.
      Added new switch CanTileManually, removed 0 use tilewithspriteops switch.

        Fixes issue where "F12 -> *BASIC -> MODE 0 -> QUIT -> return" wouldn't restore screen mode correctly if currentmode had been set to a bad mode selector (e.g. after a CMOS reset nukes the LoadModeFile command), due to WimpMode's lack of error checking
        Note that this merely prevents currentmode being set to a bad mode at the time of *WimpMode/Wimp_SetMode - if a mode which is valid suddenly becomes invalid (e.g. due to loading a new MDF but not reselecting a valid wimp mode) then the Wimp will still fail to set a sensible mode on return to the desktop.

      Protect memory above MemoryLimit being nuked when starting a task · 6911d7cc

      Detail:
        s/Wimp08s - Improve testapplication to detect situations where data is being stored above MemoryLimit, e.g. if a C app uses system() to issue *WimpTask
        Usually the CAO check will detect this kind of situation, except for the case where a single-tasking app issues *WimpTask - in which case the CAO will get reset to the Wimp module due to ModHandReason_Enter being used to get into USR mode so a temp parent task can be created
        Wimp_SlotSize checks MemoryLimit against ApplicationSpaceSize before allowing the wimpslot to be resized, so it seems to be a bit of an oversight that the task startup code wasn't doing the same
