`LLDB_LAUNCH_FLAG_USE_PIPES=1` is used in tests to run lldb without the ConPTY on Windows. This reduces the flakyness of tests. This patch ensures that we read the value of `LLDB_LAUNCH_FLAG_USE_PIPES` when setting up gdbremote tests, to make sure they don't use the ConPTY. This fixes `tools/lldb-server/TestGdbRemote_qThreadStopInfo.py` on https://ci-external.swift.org/job/lldb-windows/job/main/. >From ec1e9644878bcfad9be999c4813685103b0ce8ea Mon Sep 17 00:00:00 2001 From: Charles Zablit <[email protected]> Date: Fri, 26 Jun 2026 16:10:19 +0100 Subject: [PATCH] [lldb] send 0x0 size packet if LLDB_LAUNCH_FLAG_USE_PIPES is set --- .../test/tools/lldb-server/gdbremote_testcase.py | 11 +++++++++++ 1 file changed, 11 insertions(+) diff --git a/lldb/packages/Python/lldbsuite/test/tools/lldb-server/gdbremote_testcase.py b/lldb/packages/Python/lldbsuite/test/tools/lldb-server/gdbremote_testcase.py index 3e89555f24ff3..b278066e3a671 100644 --- a/lldb/packages/Python/lldbsuite/test/tools/lldb-server/gdbremote_testcase.py +++ b/lldb/packages/Python/lldbsuite/test/tools/lldb-server/gdbremote_testcase.py @@ -559,6 +559,17 @@ def do_handshake(self): server.send_ack() def add_verified_launch_packets(self, launch_args): + if os.environ.get("LLDB_LAUNCH_FLAG_USE_PIPES", 0) == 1: + self.test_sequence.add_log_lines( + [ + "read packet: %s" + % gdbremote_packet_encode_string( + "QSetSTDIOWindowSize:cols=0;rows=0" + ), + "send packet: $OK#00", + ], + True, + ) self.test_sequence.add_log_lines( [ "read packet: %s" % build_gdbremote_A_packet(launch_args), _______________________________________________ lldb-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-commits
