In Python 2, dict.items(), dict.keys(), and dict.values() returned a
list. dict.iteritems(), dict.iterkeys(), and dict.itervalues() returned
an iterator.
As of Python 3, dict.iteritems(), dict.itervalues(), and dict.iterkeys()
are gone. items(), keys(), and values() now return an iterator.
In the case where we want an iterator, we now use the six.iter*()
helpers. If we want a list, we explicitly create a list from the
iterator.

Python 2 had range() and xrange(). xrange() is more efficient, but
behaves differently so range() was retained for compatibility. Python 3
only has range() and it behaves like Python 2's xrange().
Remove explicit use of xrange() and use six.moves.range() to
make sure we're using xrange() from Python 2 or range() from Python 3.

class Vlog now inherits from "object". This is a "new style" Python
class, which isn't new at all at this point. This was introduced back
in Python 2.2, and some Python 2 code won't work as expected without it.

commit 7905aae3fc
("vlog: Don't fail syslog initialization in chroot.")
uses os.path.isfile("/dev/log"), which tests if the given path
is a regular file, to see if syslog can be usable.
However, /dev/log is not a regular file for platforms I looked at.
* On Ubuntu 14.04 and CentOS 6.5, /dev/log is a socket
* On NetBSD-6, /dev/log is a symlink to a socket
Replace the test with os.path.exists() so that it can work
as intended for these platforms.

When OVS unit tests are run inside chroot environment,
there is no syslog infrastructure available. In a
situation like that, don't fail or log additional messages
to syslog by increasing the severity level of syslog very high
(log messages would continue to be logged to console and file).

When Open vSwitch is run in hundreds of hypervisors, it is
useful to collect log messages through log collectors. To
collect log messages like this, it is useful to log them
in a particular RFC5424 facility in the local system. The
log collectors can then be used to collect logs anytime
desired.
This commit provides a sysadmin the ability to specify the
facility through which the log messages are logged.

In OVS, we currently use the term 'facility' to mean the place
where we log (syslog, console or file). In Linux's syslog() and
rfc5424, the term 'facility' is used to specify what type of program
is logging the message (e.g: LOG_DAEMON). This causes confusion
while reading vlog's code. This commit changes the term 'facility'
to 'destination'.

The Open vSwitch daemons written in C support user-configured logging
patterns as described in ovs-appctl(8). This commit adds this capability
to the daemons written in Python.
- Add a '__log_patterns' attribute to the Vlog class
- Populate this using the default patterns in ovs-appctl(8)
- Add a '__start_time' attribute to the Vlog class to support '%r'
- Update the '_log' method to build the log message according to the
pattern
- Add a 'set_pattern' method to allow the default patterns to be changed
- Update 'set_levels_from_string' to support setting the pattern from a
string

This suppresses a testsuite failure when the testsuite is run from a

Commit 2b31d8e713 (vlog: Report timestamps in millisecond resolution in
log messages.) introduced milliseconds to log messages by default, but the
Python version did not ensure that milliseconds were always formatted with
3 digits, so 3.001 was formatted as "3.1" and 3.012 as "3.12", and so on.
This commit fixes the problem.

vlog.py currently generates the same log messages, starts with the time stamp
information, for console, syslog and file. All messages start with current
time stamp information.
Syslogd, by default, prepends time stamp with each message already. Thus
the time stamp generated by vlog.py is redundant.
This patch removes time stamp from the message before vlog.py sends it
to syslogd.

This doesn't implement control over log patterns, though.
The change to vlog.man in this commit doesn't have any practical effect
because OVS doesn't come with any Python daemons that have their own

Currently, each python daemon has to come up with it's own logging
solution. These logging strategies are not consistent across the
python code or with the C vlog module. This patch adds a new
logging module which hopes to solve the problem. This new module
generates log messages in a manner consistent with the C code.
Furthermore, it can easily be extended to support things like rate
limiters in the future.
This patch does not update any python code to use the new module.
