These failures were recently introduced but went undiscovered due to
some recent instability in the test suite (which has now been fixed).
This commit fixes these failing tests.
moto versions >= 1.0.0 have changed the way the mocked connections through
boto are handled with the @mock_ec2 decorator. They use the boto3 connection
method. However, since we are still using boto in many places, we need to use
the new @mock_ec2_deprecated decorator instead to handle the boto connection
functions for the unit tests.
Versions of moto < 1.0.0 are not Python 3 compatible, so salt-jenkins should
be installing newer versions of moto for those tests. Unfortunately, we cannot
install an older version of moto for Python2 that use the original @mock_ec2 call
and also import the @mock_ec2_deprecated function for newer versions of moto
simultaneously as the @mock_ec2_deprecated function doesn't exist in older
versions of moto.
This PR is part of what will be an ongoing effort to use explicit
unicode strings in Salt. Because Python 3 does not suport Python 2's raw
unicode string syntax (i.e. `ur'\d+'`), we must use
`salt.utils.locales.sdecode()` to ensure that the raw string is unicode.
However, because of how `salt/utils/__init__.py` has evolved into the
hulking monstrosity it is today, this means importing a large module in
places where it is not needed, which could negatively impact
performance. For this reason, this PR also breaks out some of the
functions from `salt/utils/__init__.py` into new/existing modules under
`salt/utils/`. The long term goal will be that the modules within this
directory do not depend on importing `salt.utils`.
A summary of the changes in this PR is as follows:
* Moves the following functions from `salt.utils` to new locations
(including a deprecation warning if invoked from `salt.utils`):
`to_bytes`, `to_str`, `to_unicode`, `str_to_num`, `is_quoted`,
`dequote`, `is_hex`, `is_bin_str`, `rand_string`,
`contains_whitespace`, `clean_kwargs`, `invalid_kwargs`, `which`,
`which_bin`, `path_join`, `shlex_split`, `rand_str`, `is_windows`,
`is_proxy`, `is_linux`, `is_darwin`, `is_sunos`, `is_smartos`,
`is_smartos_globalzone`, `is_smartos_zone`, `is_freebsd`, `is_netbsd`,
`is_openbsd`, `is_aix`
* Moves the functions already deprecated by @rallytime to the bottom of
`salt/utils/__init__.py` for better organization, so we can keep the
deprecated ones separate from the ones yet to be deprecated as we
continue to break up `salt.utils`
* Updates `salt/*.py` and all files under `salt/client/` to use explicit
unicode string literals.
* Gets rid of implicit imports of `salt.utils` (e.g. `from salt.utils
import foo` becomes `import salt.utils.foo as foo`).
* Renames the `test.rand_str` function to `test.random_hash` to more
accurately reflect what it does
* Modifies `salt.utils.stringutils.random()` (née `salt.utils.rand_string()`)
such that it returns a string matching the passed size. Previously
this function would get `size` bytes from `os.urandom()`,
base64-encode it, and return the result, which would in most cases not
be equal to the passed size.
For Python 2 tests, we can use an older version. But when running
these tests of Python 3, we need a newer version of moto that supports
Python 3.
This gates the tests if the expected version of moto is missing.
