Return the textual or numeric representation of logging level 'level'.
If the level is one of the predefined levels (CRITICAL, ERROR, WARNING,
INFO, DEBUG) then you get the corresponding string. If you have
associated levels with names using addLevelName then the name you have
associated with 'level' is returned.
If a numeric value corresponding to one of the defined levels is passed
in, the corresponding string representation is returned.
If a string representation of the level is passed in, the corresponding
numeric value is returned.
If no matching numeric or string value is passed in, the string
'Level %s' % level is returned.

Formatter instances are used to convert a LogRecord to text.
Formatters need to know how a LogRecord is constructed. They are
responsible for converting a LogRecord to (usually) a string which can
be interpreted by either a human or an external system. The base Formatter
allows a formatting string to be specified. If none is supplied, the
style-dependent default value, "%(message)s", "{message}", or
"${message}", is used.
The Formatter can be initialized with a format string which makes use of
knowledge of the LogRecord attributes - e.g. the default value mentioned
above makes use of the fact that the user's message and arguments are pre-
formatted into a LogRecord's message attribute. Currently, the useful
attributes in a LogRecord are described by:
%(name)s Name of the logger (logging channel)
%(levelno)s Numeric logging level for the message (DEBUG, INFO,
WARNING, ERROR, CRITICAL)
%(levelname)s Text logging level for the message ("DEBUG", "INFO",
"WARNING", "ERROR", "CRITICAL")
%(pathname)s Full pathname of the source file where the logging
call was issued (if available)
%(filename)s Filename portion of pathname
%(module)s Module (name portion of filename)
%(lineno)d Source line number where the logging call was issued
(if available)
%(funcName)s Function name
%(created)f Time when the LogRecord was created (time.time()
return value)
%(asctime)s Textual time when the LogRecord was created
%(msecs)d Millisecond portion of the creation time
%(relativeCreated)d Time in milliseconds when the LogRecord was created,
relative to the time the logging module was loaded
(typically at application startup time)
%(thread)d Thread ID (if available)
%(threadName)s Thread name (if available)
%(process)d Process ID (if available)
%(message)s The result of record.getMessage(), computed just as
the record is emitted
Nr Tr c : |t vr>> LLNN RSS6T>>#2#Ar; c 4 | j S )zK
Check if the format uses the creation time of the record.

This method is provided as an extension point for specialized
formatting of stack information.
The input data is a string as returned from a call to
:func:`traceback.print_stack`, but with the last trailing newline
removed.
The base implementation just returns the value passed in.

Format the specified record as text.
The record's attribute dictionary is used as the operand to a
string formatting operation which yields the returned string.
Before formatting the dictionary, a couple of preparatory steps
are carried out. The message attribute of the record is computed
using LogRecord.getMessage(). If the formatting string uses the
time (as determined by a call to usesTime(), formatTime() is
called to format the event time. If there is exception information,
it is formatted using formatException() and appended to the message.

Determine if a record is loggable by consulting all the filters.
The default is to allow the record to be logged; any filter can veto
this and the record is then dropped. Returns a zero value if a record
is to be dropped, else non-zero.

The base handler class. Acts as a placeholder which defines the Handler
interface. Handlers can optionally use Formatter instances to format
records as desired. By default, no formatter is specified; in this case,
the 'raw' message as determined by record.message is logged.

Handle errors which occur during an emit() call.
This method should be called from handlers when an exception is
encountered during an emit() call. If raiseExceptions is false,
exceptions get silently ignored. This is what is mostly wanted
for a logging system - most users will not care about errors in
the logging system, they are more interested in application errors.
You could, however, replace this with a custom handler if you wish.
The record which was being processed is passed in to this method.

If a formatter is specified, it is used to format the record.
The record is then written to the stream with a trailing newline. If
exception information is present, it is formatted using
traceback.print_exception and appended to the stream. If the stream
has an 'encoding' attribute, it is used to determine how to do the
output to the stream.

Instances of the Logger class represent a single logging channel. A
"logging channel" indicates an area of an application. Exactly how an
"area" is defined is up to the application developer. Since an
application can have any number of areas, logging channels are identified
by a unique string. Application areas can be nested (e.g. an area
of "input processing" might include sub-areas "read CSV files", "read
XLS files" and "read Gnumeric files"). To cater for this natural nesting,
channel names are organized into a namespace hierarchy where levels are
separated by periods, much like the Java or Python package namespace. So
in the instance given above, channel names might be "input" for the upper
level, and "input.csv", "input.xls" and "input.gnu" for the sub-levels.
There is no arbitrary limit to the depth of nesting.

An adapter for loggers which makes it easier to specify contextual
information in logging output.
Nc " || _ || _ dS )ax
Initialize the adapter with a logger and a dict-like object which
provides contextual information. This constructor signature allows
easy stacking of LoggerAdapters, if so desired.
You can effectively pass keyword arguments as shown in the
following example:
adapter = LoggerAdapter(someLogger, dict(p1=v1, p2="v2"))
N)r r )r r r s r< r zLoggerAdapter.__init__ s

Process the logging message and keyword arguments passed in to
a logging call to insert contextual information. You can either
manipulate the message itself, the keyword args or both. Return
the message and kwargs modified (or not) to suit your needs.
Normally, you'll only need to override this one method in a
LoggerAdapter subclass for your specific needs.
