◆ Thread() [1/2]

Thread::Thread	(	Process &	process,
		lldb::tid_t	tid,
		bool	use_invalid_index_id = `false`
	)

Constructor.

Parameters

[in] use_invalid_index_id Optional parameter, defaults to false. The only subclass that is likely to set use_invalid_index_id == true is the HistoryThread class. In that case, the Thread we are constructing represents a thread from earlier in the program execution. We may have the tid of the original thread that they represent but we don't want to reuse the IndexID of that thread, or create a new one. If a client wants to know the original thread's IndexID, they should use Thread::GetExtendedBacktraceOriginatingIndexID().

◆ CalculateStopInfo()

virtual bool lldb_private::Thread::CalculateStopInfo ( )

pure virtual

Ask the thread subclass to set its stop info.

Thread subclasses should call Thread::SetStopInfo(...) with the reason the thread stopped.

A thread that is sitting at a breakpoint site, but has not yet executed the breakpoint instruction, should have a breakpoint-hit StopInfo set. When execution is resumed, any thread sitting at a breakpoint site will instruction-step over the breakpoint instruction silently, and we will never record this breakpoint as being hit, updating the hit count, possibly executing breakpoint commands or conditions.

Returns: True if Thread::SetStopInfo(...) was called, false otherwise.

Implemented in ThreadElfCore, ThreadFreeBSDKernel, lldb_private::process_gdb_remote::ThreadGDBRemote, ThreadMachCore, ThreadKDP, lldb_private::minidump::ThreadMinidump, lldb_private::ScriptedThread, lldb_private::HistoryThread, ThreadMemory, lldb_private::TargetThreadWindows, and lldb_private::ThreadPostMortemTrace.

GetStackFrameCount can be expensive.

Stacks can get very deep, and they require memory reads for each frame. So only use GetStackFrameCount when you need to know the depth of the stack. When iterating over frames, its better to generate the frames one by one with GetFrameAtIndex, and when that returns NULL, you are at the end of the stack. That way your loop will only do the work it needs to, without forcing lldb to realize StackFrames you weren't going to look at.

◆ QueueBasePlan()

ThreadPlanSP Thread::QueueBasePlan ( bool abort_other_plans )

Queues the base plan for a thread.

The version returned by Process does some things that are useful, like handle breakpoints and signals, so if you return a plugin specific one you probably want to call through to the Process one for anything your plugin doesn't explicitly handle.

Parameters

[in] abort_other_plans true if we discard the currently queued plans and replace them with this one. Otherwise this plan will go on the end of the plan stack.

Returns: A shared pointer to the newly queued thread plan, or nullptr if the plan could not be queued.

Parameters

[in]	abort_other_plans	true if we discard the currently queued plans and replace them with this one. Otherwise this plan will go on the end of the plan stack.

Returns: A pointer to the last completed plan.

	)

virtual

Queue the plan used to step out of the function at the current PC of a thread.

This version does not consult the should stop here callback, and should only be used by other thread plans when they need to retain control of the step out.

Parameters

[in]	abort_other_plans	true if we discard the currently queued plans and replace them with this one. Otherwise this plan will go on the end of the plan stack.
[in]	addr_context	When dealing with stepping through inlined functions the current PC is not enough information to know what "step" means. For instance a series of nested inline functions might start at the same address. is supposed to be out of.

[in]	report_stop_vote	See standard meanings for the stop & run votes in ThreadPlan.h.
[in]	report_run_vote	See standard meanings for the stop & run votes in ThreadPlan.h.
[in]	frame_idx	The frame index.
[out]	status	A status with an error if queuing failed.
[in]	continue_to_next_branch	Normally this will enqueue a plan that will put a breakpoint on the return address and continue to there. If continue_to_next_branch is true, this is an operation not involving the user – e.g. stepping "next" in a source line and we instruction stepped into another function – so instead of putting a breakpoint on the return address, advance the breakpoint to the end of the source line that is doing the call, or until the next flow control instruction. If the return value from the function call is to be retrieved / displayed to the user, you must stop on the return address. The return value may be stored in volatile registers which are overwritten before the next branch instruction.

Returns: A shared pointer to the newly queued thread plan, or nullptr if the plan could not be queued.

◆ SetResumeState()

void lldb_private::Thread::SetResumeState	(	lldb::StateType	state,

inline

Sets the USER resume state for this thread.

If you set a thread to suspended with this API, it won't take part in any of the arbitration for ShouldResume, and will stay suspended even when other threads do get to run.

N.B. This is not the state that is used internally by thread plans to implement staying on one thread while stepping over a breakpoint, etc. The is the TemporaryResume state, and if you are implementing some bit of strategy in the stepping machinery you should be using that state and not the user resume state.

If you are just preparing all threads to run, you should not override the threads that are marked as suspended by the debugger. In that case, pass override_suspend = false. If you want to force the thread to run (e.g. the "thread continue" command, or are resetting the state (e.g. in SBThread::Resume()), then pass true to override_suspend.

	)

virtual

Default implementation for stepping into.

This function is designed to be used by commands where the process is publicly stopped.

Parameters

[in]	source_step	If true and the frame has debug info, then do a source level step in, else do a single instruction step in.
[in]	step_in_avoids_code_without_debug_info	If true, then avoid stepping into code that doesn't have debug info, else step into any code regardless of whether it has debug info.
[in]	step_out_avoids_code_without_debug_info	If true, then if you step out to code with no debug info, keep stepping out till you get to code with debug info.

Returns: An error that describes anything that went wrong

◆ ThreadHasQueueInformation()

virtual bool lldb_private::Thread::ThreadHasQueueInformation ( ) const

inlinevirtual

Whether this Thread already has all the Queue information cached or not.

A Thread may be associated with a libdispatch work Queue at a given public stop event. If so, the thread can satisify requests like GetQueueLibdispatchQueueAddress, GetQueueKind, GetQueueName, and GetQueueID either from information from the remote debug stub when it is initially created, or it can query the SystemRuntime for that information.

This method allows the SystemRuntime to discover if a thread has this information already, instead of calling the thread to get the information and having the thread call the SystemRuntime again.
