[lldb][test] Remove duplicate testcase names in API test-suite (#97043) In one of my recent PRs I mistakenly had two test-cases with the same name, preventing one of them to run. Since it's an easy mistake to make (e.g., copy pasting existing test-cases), I ran following sanity-check script over lldb/test/API, which found couple of tests which were losing coverage because of this (or in some cases simply had duplicate tests): import ast import sys filename = sys.argv[1] print(f'Checking {filename}...') tree = ast.parse(open(filename, 'r').read()) for node in ast.walk(tree): if not isinstance(node, ast.ClassDef): continue func_names = [] for child in ast.iter_child_nodes(node): if isinstance(child, ast.FunctionDef): func_names.append(child.name) seen_func_names = set() duplicate_func_names = [] for name in func_names: if name in seen_func_names: duplicate_func_names.append(name) else: seen_func_names.add(name) if len(duplicate_func_names) != 0: print(f'Multiple func names found:\n\t{duplicate_func_names}\n\tclass {node.name}\n\tfile: {filename}') This patch fixes these cases. | 2 年前 | |
Add option to pass thread ID to thread select command (#73596) We'd like a way to select the current thread by its thread ID (rather than its internal LLDB thread index). This PR adds a -t option (--thread_id long option) that tells the thread select command to interpret the <thread-index> argument as a thread ID. Here's an example of it working: `` michristensen@devbig356 llvm/llvm-project (thread-select-tid) » ../Debug/bin/lldb ~/scratch/cpp/threading/a.out (lldb) target create "/home/michristensen/scratch/cpp/threading/a.out" Current executable set to '/home/michristensen/scratch/cpp/threading/a.out' (x86_64).

This command takes options and free-form arguments. If your arguments resemble option specifiers (i.e., they start with a - or --), you must use ' -- ' between the end of the command options and the beginning of the arguments.
