See Below was confusing because it linked to the entire documentation section.
This provides a direct link to the section explaining why TCP over TCP is a bad idea.

* Make hostwatch locale-independent

See #377: hostwatch used to call netstat and parse the result,
without setting the locale.
The problem is converting the binary output to a unicode string,
as the locale may be utf-8, latin-1, or literally anything.
Setting the locale to C avoids this issue, as netstat's source
strings to not use non-ASCII characters.

* Break line, check all other invocations

This commit resolves #297, allowing the buffers used in the latency control to be changed with a command line option ‘--latency-buffer-size’.

We do this by changing a module variable in ssnet.py (similar to the MAX_CHANNEL variable) which seems to be the simplest code change without extensive hacking.

Documentation is also updated.

The changes in a765aa32 removed a more complex pieced of code for parsing which sudo command to use. The %(eb)s no longer refers to any variable and is directly printed to the command line.

%(eb)s is now replaced with ‘sudo’.

Latest version of attrs breaks pytest, see:

Regression was introduced in #337 that is skipping all local traffic,
including DNS. This change makes UDP port 53 (DNS) LOCAL traffic to be
treated as special case.

Fixes #357

In certain cases socket.connect fails with ECONNABORTED, which is
treated as "unknown" error causing sshuttle to crash.

Fixes #356

`pacman -Sy` does a partial upgrade, which is specifically documented as being unsupported.

Correct the install flag for arch linux installation example.

* use addrtype match to return the LOCAL trafik

* Add assertion for the new LOCAL firewall rule added in PR 312.

* Fix linter complaints

* assembler import fix.
* Added noqa to import statements.

* re-organized imports according to pep8
* fixed all remaining pep8 issues
* moved common config into setup.cfg, additionally test `tests`
* removed --select=X -- the errors selected where by default not in
  flake8's --ignore list so effectively had no effect
* update .travis.yml to reflect changes in tox.ini

* replace py.test with pytest
* fixed .travis.yml
* try different pypy toxenv
* hopefully fixed testenv for pypy
* added pypy basepython, removed unused python2.6
* install dev package before testing (fixes missing coverage)
* fixed empty exception pass blocks with noqa
* Added dummy log message on empty try-except-pass blocks to make dodacy happy :(
* Replaced Exception with BaseException

There's a known issue that makes sshuttle crash if there are too
many routes on the remote host (that don't fit in 64KB). This patch
requests the routes only if auto-nets is specified on the command
line.

This was susceptible to the same deadlock issue that ipt_chain_exists
had and was fixed in d43db80d where if the command returned a significant
amount of output, it wouldn't all be read in, resulting in the
subprocess hanging waiting for the output to be read.

subprocess.run only exists for python3, and this needs to also support
python 2.7

--ns-hosts is available since commit d2ee34d7
("dns: Added --ns-hosts to tunnel only some requests")
(released as v0.72), but was never documented.

--to-ns is available since commit be559fc7
("Fix case where there is no --dns.") after several
bugfixes, released as v0.78.4, but was never
documented.
