From ad9b69789837c01a8372babf59367019c06b9c27 Mon Sep 17 00:00:00 2001 From: Stella Stamenova Date: Mon, 14 May 2018 21:04:24 +0000 Subject: [PATCH] [lit] Fix several tests that fail when using Python 3 or on Windows Summary: 1) In logtest.cpp, the name of the file that is reported is not always capitalized, so split the comparison to validate the file (case insensitive) and function (case sensitive) separately 2) Update the gdb remote client tests to work with Python 3. In Python 3, socket sends/receives data as bytes rather than byte strings. This also updates the usage of .hex() - this is no longer available in Python 3, so use hexlify instead Reviewers: asmith, labath, zturner Reviewed By: labath Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D46773 llvm-svn: 332293 --- .../gdb_remote_client/TestGDBRemoteClient.py | 3 ++- .../gdb_remote_client/gdbclientutils.py | 19 ++++++++++++++----- lldb/unittests/Utility/LogTest.cpp | 17 +++++++++++------ 3 files changed, 27 insertions(+), 12 deletions(-) diff --git a/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/TestGDBRemoteClient.py b/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/TestGDBRemoteClient.py index 7fef9df6fc2a..3bf0c52edaed 100644 --- a/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/TestGDBRemoteClient.py +++ b/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/TestGDBRemoteClient.py @@ -1,4 +1,5 @@ import lldb +import binascii from lldbsuite.test.lldbtest import * from lldbsuite.test.decorators import * from gdbclientutils import * @@ -25,7 +26,7 @@ class TestGDBRemoteClient(GDBRemoteTestBase): # Then, when we are asked to attach, error out. def vAttach(self, pid): - return "E42;" + error_msg.encode("hex") + return "E42;" + binascii.hexlify(error_msg.encode()).decode() self.server.responder = MyResponder() diff --git a/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/gdbclientutils.py b/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/gdbclientutils.py index 34e5dc3e163c..ebafd405e23e 100644 --- a/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/gdbclientutils.py +++ b/lldb/packages/Python/lldbsuite/test/functionalities/gdb_remote_client/gdbclientutils.py @@ -76,7 +76,7 @@ def hex_decode_bytes(hex_bytes): class MockGDBServerResponder: """ - A base class for handing client packets and issuing server responses for + A base class for handling client packets and issuing server responses for GDB tests.
