Template Sync: Use contextlib.suppress instead of try-except-pass

🔄 Template Sync Required

Changes from the upstream vscode-python-tools-extension-template have not yet been incorporated into this repository.

Source PR

• Use contextlib.suppress instead of try-except-pass vscode-python-tools-extension-template#204 — Use contextlib.suppress instead of try-except-pass

Summary

The template replaced bare except: pass and except SystemExit: pass patterns with the idiomatic contextlib.suppress(...) context manager. This improves code clarity and eliminates pylint bare-except warnings.

Files with missing changes

• bundled/tool/lsp_jsonrpc.py: Three bare-except blocks (except: # pylint: disable=bare-except followed by pass) in the close() and stop_all_processes() methods have not been replaced with contextlib.suppress(Exception). The import contextlib statement is also missing.
• bundled/tool/lsp_utils.py: Two try...except SystemExit: pass blocks in _run_module() (line ~161) and _run_api() (line ~240) have not been replaced with with contextlib.suppress(SystemExit):.

Suggested fix

bundled/tool/lsp_jsonrpc.py — add import contextlib and replace bare-except blocks:

 import atexit
+import contextlib
 import io

     def close(self):
         """Closes the underlying streams."""
-        try:
+        with contextlib.suppress(Exception):
             self._reader.close()
-        except:  # pylint: disable=bare-except
-            pass
-        try:
+        with contextlib.suppress(Exception):
             self._writer.close()
-        except:  # pylint: disable=bare-except
-            pass

     def stop_all_processes(self):
         """Send exit command to all processes and shutdown transport."""
         for i in self._rpc.values():
-            try:
+            with contextlib.suppress(Exception):
                 i.send_data({"id": str(uuid.uuid4()), "method": "exit"})
-            except:  # pylint: disable=bare-except
-                pass
         self._thread_pool.shutdown(wait=False)

bundled/tool/lsp_utils.py — replace both except SystemExit: pass blocks (in _run_module and _run_api):

-    try:
+    with contextlib.suppress(SystemExit):
         with substitute_attr(sys, "argv", argv):
             with redirect_io("stdout", str_output):
                 with redirect_io("stderr", str_error):
                     if use_stdin and source is not None:
                         ...
                     else:
                         runpy.run_module(module, run_name="__main__")
-    except SystemExit:
-        pass

Apply the same pattern for the _run_api function.
