<H1><A name="plugin"></A>Debugger: Editing Machine State</H1>
<P>This plugin controls the modification of machine state. It provides a multi-state action in
the main toolbar for controlling the editing mode of each trace and associated target. It is
backed by a corresponding service plugin which manages the editing modes and dispatches
machine-state edits accordingly. Scripts can also use the service to perform machine-state
edits that behave consistently with the rest of the UI.</P>
<H2>Actions</H2>
<P>The plugin provides a single action:</P>
<H3><A name="edit_mode"></A>Edit Mode</H3>
<P>This action is available whenever a trace is active. It changes the machine-state editing
mode for the active trace and, if applicable, its associated target. The possible modes
are:</P>
<UL>
<LI><IMG alt="" src="images/write-disabled.png"> Read-Only - Rejects all edits.</LI>
<LI><IMG alt="" src="images/write-target.png"> Write Target - The default, this directs edits
to the live target. To accept changes, the UI must be "live and at the present." If the trace
has no associated target, i.e., it is dead; or if the current view is in the past or includes
any steps of emulation, i.e., it is not at the present; then edits are rejected.</LI>
<LI><IMG alt="" src="images/write-trace.png"> Write Trace - Directs all edits to the trace.
Edits are generally always accepted, and they are applied directly to the trace.</LI>
<LI><IMG alt="" src="images/write-emulator.png"> Write Emulator - Materializes edits via
emulation. Instead of editing the trace, this generates a patch and appends it to the current
coordinates' emulation schedule. See the <A href=
"help/topics/DebuggerThreadsPlugin/DebuggerThreadsPlugin.html#goto_time">Go To Time</A>
action. Essentially, the change is applied in the trace's scratch space, leaving the original
recording in tact. Due to implementation details, a thread must be selected, even if edits
only affect memory. Additionally, the disassembly context register cannot be modified.</LI>
</UL>
<H2>Recommendations</H2>
<P>Write Target is the default mode, because in most cases, this is the desired behavior. When
the target dies, Write Target essentially means Read Only. For the most part, modifying the
recording itself is discouraged. There are few reasons, perhaps including 1) Hand-generating an
experimental trace; 2) Generating a trace from a script, e.g., importing an event log,
recording an emulated target; 3) Patching in state missed by the original recording. More often
than not, when experimenting with the emulator, the mode should be Write Emulator. Using Write
Trace with the emulator will almost certainly result in issues with cache staleness.</P>
<P>Some background and an example: To display emulated machine state, the emulator executes a
specified schedule and writes the resulting state into the trace's scratch space, keyed by the
schedule. Suppose you emulate a step forward but then realize that some state was incorrect, or
you just want to try the same step with an alternative initial state. If you step back then
edit the trace and then repeat the step forward, the UI will simply recall the cached snapshot,
rendering the state change ineffective. Instead, use Write Emulator to edit the state and then
step forward. Because the patch is encoded in the emulation schedule, the UI will not recall
the stale snapshot. Instead the emulator will execute the new schedule and generate a new
scratch snapshot. Furthermore, the original trace recording remains in tact, while the modified
state is stored in scratch space with the schedule explaining where it came from. Still better,
the first scratch snapshot (for the step taken without first modifying the state) also remains
in tact, and the two can be <A href=
"help/topics/DebuggerTraceViewDiffPlugin/DebuggerTraceViewDiffPlugin.html">compared</A>.</P>
<P>To prevent edits to a live target, use the Read-Only mode. This will prevent most accidental
edits. This is only effective against edits from the UI, and only when all plugins and scripts
use the state editing service. This cannot prevent a component from accessing Ghidra's Target
API to modify a target. Nor can it prevent edits via the connected debugger's command-line
interpreter. The following components all use the service: <A href=
