From c46bfed1a484d30cd251a9a225649d74e3bf0af5 Mon Sep 17 00:00:00 2001 From: Ebuka Ezike Date: Thu, 30 Oct 2025 21:43:53 +0000 Subject: [lldb] Add alternative SBThread::GetStopDescription (#165379) the function signature for `GetStopDescription` is `lldb::SBThread::GetStopDescription(char *dst_or_null, size_t len)`. To get a description you need to call the function first time to get the buffer size. a second time to get the description. This is little worse from the python size as the signature is `lldb.SBThread.GetStopDescription(int: len) -> list[str]` the user has to pass the max size as possible with no way of checking if it is enough. This patch adds a new api `lldb.SBThread.GetStopDescription(desc: lldb.SBStream()) -> bool` `bool lldb::SBThread::GetStopDescription(lldb::SBStream &description)` which handles this case. Adds new Test case for lua. --- lldb/test/API/lua_api/TestThreadAPI.lua | 25 +++++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 lldb/test/API/lua_api/TestThreadAPI.lua (limited to 'lldb/test/API/lua_api/TestThreadAPI.lua') diff --git a/lldb/test/API/lua_api/TestThreadAPI.lua b/lldb/test/API/lua_api/TestThreadAPI.lua new file mode 100644 index 0000000..5a38d0b --- /dev/null +++ b/lldb/test/API/lua_api/TestThreadAPI.lua @@ -0,0 +1,25 @@ +_T = require('lua_lldb_test').create_test('TestThreadAPI') + +function _T:TestGetStopDescription() + local target = self:create_target() + local breakpoint = target:BreakpointCreateByName("main", "a.out") + assertTrue(breakpoint:IsValid() and breakpoint:GetNumLocations() == 1) + + local process = target:LaunchSimple({ 'arg1', 'arg2' }, nil, nil) + local thread = get_stopped_thread(process, lldb.eStopReasonBreakpoint) + assertNotNil(thread) + assertTrue(thread:IsValid()) + + assertEqual("breakpoint", thread:GetStopDescription(string.len("breakpoint") + 1)) + assertEqual("break", thread:GetStopDescription(string.len("break") + 1)) + assertEqual("b", thread:GetStopDescription(string.len("b") + 1)) + assertEqual("breakpoint 1.1", thread:GetStopDescription(string.len("breakpoint 1.1") + 100)) + + -- Test stream variation + local stream = lldb.SBStream() + assertTrue(thread:GetStopDescription(stream)) + assertNotNil(stream) + assertEqual("breakpoint 1.1", stream:GetData()) +end + +os.exit(_T:run()) -- cgit v1.1
