-- Fixed release script. [Jose Diaz-Gonzalez]
+- Specify a max queue size of 100 to limit overrunning memory. [Jose
+ Diaz-Gonzalez]
+- Use multiprocessing for handling larger queue sizes. [Jose Diaz-
+ Gonzalez]
+ Previously there were issues where files that were updated frequently
+ such as varnish or server logs
+ would overwhelm the naive implementation of file.readlines() within
+ Beaver. This would cause Beaver to slowly read larger and larger
+ portions of a file before processing any of the lines, eventually
+ causing Beaver to take forever to process log lines.
+ This patch adds the ability to use an internal work queue for log
+ lines. Whenever file.readlines() is called, the lines are placed in
+ the queue, which is shared with a child process. The child process
+ creates its own transport, allowing us to potentially create a Process
+ Pool in the future to handle a larger queue size.
+ Note that the limitation of file.readlines() reading in too many lines
+ is still in existence, and may continue to cause issues for certain
+ log files.
+- Add default redis_password to BeaverConfig class. [Jose Diaz-Gonzalez]
+- Fix missing underscore causing transport to break. [Norman Joyner]
+- Implement redis auth support. [Norman Joyner]
+- Add beaver init script for daemonization mode. [Jose Diaz-Gonzalez]
+- Use python logger when using StdoutTransport. [Jose Diaz-Gonzalez]
+- Add short arg flags for hostname and format. [Jose Diaz-Gonzalez]
+- Add the ability to daemonize. Closes #79. [Jose Diaz-Gonzalez]
+- Pass around a logger instance to all transports. [Jose Diaz-Gonzalez]
+- Revert "Added a lightweight Event class" [Jose Diaz-Gonzalez]
+ After deliberation, beaver is meant to be "light
+ weight". Lets leave
+ the heavy
+ hitting to the big
+ boys.
+ This reverts commit 1619d33ef4803c3fe910cf4ff197d0dd0039d2eb.
+- Added a lightweight Event class. [Jose Diaz-Gonzalez]
+ This class's sole responsibility will be the processing of a given
+ line as an event.
+ It's future goal will be to act as a lightweight implementation of the
+ filter system within Logstash
+- Remove argparse requirement for python 2.7 and above. [Jose Diaz-
+ Gonzalez]

- General code reorganization. [Jose Diaz-Gonzalez]
Move both BeaverConfig and FileConfig into a single class
Consolidated run_worker code with code in beaver binary file. This
will create a clearer path for Exception handling, as it is now the
responsibility of the calling class, allowing us to remove duplicative
exception handling code.
Added docstrings to many fuctions and methods
Moved extra configuration and setup code to beaver.utils module. In
many cases, code was added hastily before.
Made many logger calls debug as opposed to info. The info level should
be generally reserved for instances where files are watched,
unwatched, or some change in the file state has occurred.

We now use a `_formatter` property on the Transport class which

In the case of string output, we define a custom formatter using an

This code should allow us to create an ssh tunnel between two distinct

`` caches the EOF, therefore causing `readlines()` to only
work once. This happens to also fail miserably when you are seeking to
the end before calling readlines.
This fix solves the issue by constantly re
reading the files changed.
Note that this also causes debug mode to be very noisy on OS X. We all
have to make sacrifices...

For my setup I need to have the fqdn used at all times since my
hostnames are the same but the environment (among other things) is
found in the rest of the FQDN.
Since just changing socket.gethostname to socket.getfqdn has lots of
potential for breakage, and socket.gethostname doesn't always return
FQDN, it's now an option to explicitly always use the fqdn.
Fixes #68
- Check for log file truncation fixes #55. [Jeremy Kitchen]
This adds a simple check for log file truncation and resets the watch
when detected.
There do exist 2 race conditions here:
1. Any log data written prior to truncation which beaver has not yet
read and processed is lost. Nothing we can do about that.

the original file during the sleep interval, beaver won't detect
this. After some experimentation, this behavior also exists in GNU
tail, so I'm going to call this a "don't do that then" bug :)
Additionally, the files beaver will most likely be called upon to
watch which may be truncated are generally going to be large enough
and slow
