From dd2382c613db6f3dd72a25c74d5f765006aea31f Mon Sep 17 00:00:00 2001 From: kshithijiyer Date: Wed, 1 Apr 2020 10:44:54 +0530 Subject: [Libfix] Remove rpyc_get_connection() dependency from code Problem: `g.rpyc_get_connection()` has a limitaion where it can't convert python2 calls to python3 calls. Due to this a large number of testcases fail when executed from a python2 machine on a python3 only setup or visa versa with the below stack trace: ``` E ========= Remote Traceback (1) ========= E Traceback (most recent call last): E File "/root/tmp.tL8Eqx7d8l/rpyc/core/protocol.py", line 323, in _dispatch_request E res = self._HANDLERS[handler](self, *args) E File "/root/tmp.tL8Eqx7d8l/rpyc/core/protocol.py", line 591, in _handle_inspect E if hasattr(self._local_objects[id_pack], '____conn__'): E File "/root/tmp.tL8Eqx7d8l/rpyc/lib/colls.py", line 110, in __getitem__ E return self._dict[key][0] E KeyError: (b'rpyc.core.service.SlaveService', 94282642994712, 140067150858560) ``` Solution: The solution here is to modify the code to not use `g.rpyc_get_connection()`. The following changes are done to accomplish it: 1)Remove code which uses g.rpyc_get_connection() and use generic logic in functions: a. do_bricks_exist_in_shd_volfile() b. get_disk_usage() c. mount_volume() d. list_files() f. append_string_to_file() 2)Create files which can be uploaded and executed on clients/servers to avoid rpc calls in functions: a. calculate_hash() b. validate_files_in_dir() 3)Modify setup.py to push the below files to `/usr/share/glustolibs/scripts/`: a.compute_hash.py b.walk_dir.py Change-Id: I00a81a88382bf3f8b366753eebdb2999260788ca Signed-off-by: kshithijiyer --- glustolibs-gluster/setup.py | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'glustolibs-gluster/setup.py') diff --git a/glustolibs-gluster/setup.py b/glustolibs-gluster/setup.py index b3f9cb09c..05e59fde6 100644 --- a/glustolibs-gluster/setup.py +++ b/glustolibs-gluster/setup.py @@ -1,5 +1,5 @@ #!/usr/bin/env python -# Copyright (c) 2016-2019 Red Hat, Inc. +# Copyright (c) 2016-2020 Red Hat, Inc. # # This program is free software; you can redistribute it and/or modify # it under the terms of the GNU General Public License as published by @@ -49,6 +49,8 @@ setup( ) try: - dir_util.copy_tree('./gdeploy_configs', '/usr/share/glustolibs/gdeploy_configs') + for srcdir, destdir in (('./gdeploy_configs', '/usr/share/glustolibs/gdeploy_configs'), + ('./scripts', '/usr/share/glustolibs/scripts/')): + dir_util.copy_tree(srcdir, destdir) except: pass -- cgit
