Now that we no longer support py27, we can use the standard library
unittest.mock module instead of the third party mock lib.

This function will call "os.path.realpth" and this in turn could call
"os.getcwd". If the current path has been deleted by other application,
this method will raise FileNotFoundError exception. This new function
catches and unsets this exception, returning an empty string.

When the daemon process is timeout, it will kill itself. But the parent
doesn't reap it. This patch add a thread to wait the process to be done
once the daemon is started.

Sphinx 1.8 introduced [1] the '--keep-going' argument which, as its name
suggests, keeps the build running when it encounters non-fatal errors.
This is exceptionally useful in avoiding a continuous edit-build loop
when undertaking large doc reworks where multiple errors may be
introduced.

Attempts have been made to correct repository namespaces and
hostnames based on simple pattern matching, but it's possible some
were updated incorrectly or missed entirely. Please reach out to us
via the contact information listed at https://opendev.org/ with any
questions you may have.

All the integration testing has been moved to
Bionic now[1] and py3.5 is not tested runtime for
Train or stable/stein[2].

As per below ML thread, we are good to drop the py35
testing now:

Change Idd98c183eca3e2df8648fc0f37d27fe9cc6d0563 stopped closing
filedescriptors beyond the sensible_fd_limit. With this patch
the previous behavior is restored. We can close the fds more efficiently
by just iterating over /proc/self/fd on Linux and only change
the rlimit/MAXFD setting when successful.

The use of the "resource" module now prevents oslo.rootwrap from
being imported on Windows.

Although oslo.rootwrap is not effectively used on Windows, it's
important for it to at least be importable, since it's widely
used throughout OpenStack projects without having platform checks
in place.

This change checks if the "resource" module is avaialble before
attempting to use it.

Developers run all sorts of different tools within Git repositories,
any of which can leave their own special trashfiles all over the
place. We can't every hope to catalog them all, so better to
recommend developers simply configure a global core.excludesfile to
filter the irrelevant files which tend to get created by their
personal choice of tools.

To this end, remove the long-standing sections for "Mr Developer"
and "Editors" since their mere existence here sends the signal that
we welcome (and have time to review) additions for any old tool
someone ever might happen to try. Also add a comment block
explaining this, for clarity.

We can, and should of course, continue to list files created by the
tools recommended by our workflow (test frameworks called from tox,
documentation and packaging builds, et cetera).

This change is a port of I1b41efac219fca44e2548fc36633724d0ecfc0cb
from the openstack-dev/oslo-cookiecutter repository.

Quotes around {posargs} cause the entire string to be combined into one
arg that gets passed to stestr. This prevents passing multiple args
(e.g. '--concurrency=16 some-regex')

On Python 2.x, a subprocess.Popen() with close_fds=True will
fork and then close filedescriptors range(3..os.sysconf("SC_OPEN_MAX")),
which thanks to Kernel PTI (Kaiser patches) is significantly slower
in 2018 when the range is very large. With a soft limit of 1048576,
benchmark.py reports an overhead of ~ 400ms without this patch and 2ms
with the patch applied. This patch adds a configuration option and
sets a more sensible default of 1024 file descriptor limit by default.
