class BufferingFormatter |
| |
A formatter suitable for formatting a number of records.
|
| |
Methods defined here:
- __init__(self, linefmt=None)
- Optionally specify a formatter which will be used to format each
individual record.
- format(self, records)
- Format the specified records and return the result as a string.
- formatFooter(self, records)
- Return the footer string for the specified records.
- formatHeader(self, records)
- Return the header string for the specified records.
|
class FileHandler(StreamHandler) |
| |
A handler class which writes formatted logging records to disk files.
|
| |
- Method resolution order:
- FileHandler
- StreamHandler
- Handler
- Filterer
Methods defined here:
- __init__(self, filename, mode='a')
- Open the specified file and use it as the stream for logging.
- close(self)
- Closes the stream.
Methods inherited from StreamHandler:
- emit(self, record)
- Emit a record.
If a formatter is specified, it is used to format the record.
The record is then written to the stream with a trailing newline
[N.B. this may be removed depending on feedback]. If exception
information is present, it is formatted using
traceback.print_exception and appended to the stream.
- flush(self)
- Flushes the stream.
Methods inherited from Handler:
- acquire(self)
- Acquire the I/O thread lock.
- createLock(self)
- Acquire a thread lock for serializing access to the underlying I/O.
- format(self, record)
- Format the specified record.
If a formatter is set, use it. Otherwise, use the default formatter
for the module.
- handle(self, record)
- Conditionally emit the specified logging record.
Emission depends on filters which may have been added to the handler.
Wrap the actual emission of the record with acquisition/release of
the I/O thread lock. Returns whether the filter passed the record for
emission.
- handleError(self, record)
- 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.
- release(self)
- Release the I/O thread lock.
- setFormatter(self, fmt)
- Set the formatter for this handler.
- setLevel(self, level)
- Set the logging level of this handler.
Methods inherited from Filterer:
- addFilter(self, filter)
- Add the specified filter to this handler.
- filter(self, record)
- 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.
- removeFilter(self, filter)
- Remove the specified filter from this handler.
|
class Filter |
| |
Filter instances are used to perform arbitrary filtering of LogRecords.
Loggers and Handlers can optionally use Filter instances to filter
records as desired. The base filter class only allows events which are
below a certain point in the logger hierarchy. For example, a filter
initialized with "A.B" will allow events logged by loggers "A.B",
"A.B.C", "A.B.C.D", "A.B.D" etc. but not "A.BB", "B.A.B" etc. If
initialized with the empty string, all events are passed.
|
| |
Methods defined here:
- __init__(self, name='')
- Initialize a filter.
Initialize with the name of the logger which, together with its
children, will have its events allowed through the filter. If no
name is specified, allow every event.
- filter(self, record)
- Determine if the specified record is to be logged.
Is the specified record to be logged? Returns 0 for no, nonzero for
yes. If deemed appropriate, the record may be modified in-place.
|
class Filterer |
| |
A base class for loggers and handlers which allows them to share
common code.
|
| |
Methods defined here:
- __init__(self)
- Initialize the list of filters to be an empty list.
- addFilter(self, filter)
- Add the specified filter to this handler.
- filter(self, record)
- 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.
- removeFilter(self, filter)
- Remove the specified filter from this handler.
|
class Formatter |
| |
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
default value of "%s(message)\n" 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)
%(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)
%(process)d Process ID (if available)
%(message)s The result of record.getMessage(), computed just as
the record is emitted
|
| |
Methods defined here:
- __init__(self, fmt=None, datefmt=None)
- Initialize the formatter with specified format strings.
Initialize the formatter either with the specified format string, or a
default as described above. Allow for specialized date formatting with
the optional datefmt argument (if omitted, you get the ISO8601 format).
- format(self, record)
- 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 contains
"%(asctime)", formatTime() is called to format the event time.
If there is exception information, it is formatted using
formatException() and appended to the message.
- formatException(self, ei)
- Format and return the specified exception information as a string.
This default implementation just uses
traceback.print_exception()
- formatTime(self, record, datefmt=None)
- Return the creation time of the specified LogRecord as formatted text.
This method should be called from format() by a formatter which
wants to make use of a formatted time. This method can be overridden
in formatters to provide for any specific requirement, but the
basic behaviour is as follows: if datefmt (a string) is specified,
it is used with time.strftime() to format the creation time of the
record. Otherwise, the ISO8601 format is used. The resulting
string is returned. This function uses a user-configurable function
to convert the creation time to a tuple. By default, time.localtime()
is used; to change this for a particular formatter instance, set the
'converter' attribute to a function with the same signature as
time.localtime() or time.gmtime(). To change it for all formatters,
for example if you want all logging times to be shown in GMT,
set the 'converter' attribute in the Formatter class.
Data and other attributes defined here:
- converter = <built-in function localtime>
- localtime([seconds]) -> (tm_year,tm_mon,tm_day,tm_hour,tm_min,tm_sec,tm_wday,tm_yday,tm_isdst)
Convert seconds since the Epoch to a time tuple expressing local time.
When 'seconds' is not passed in, convert the current time instead.
|
class Handler(Filterer) |
| |
Handler instances dispatch logging events to specific destinations.
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.
|
| |
Methods defined here:
- __init__(self, level=0)
- Initializes the instance - basically setting the formatter to None
and the filter list to empty.
- acquire(self)
- Acquire the I/O thread lock.
- close(self)
- Tidy up any resources used by the handler.
This version does nothing and is intended to be implemented by
subclasses.
- createLock(self)
- Acquire a thread lock for serializing access to the underlying I/O.
- emit(self, record)
- Do whatever it takes to actually log the specified logging record.
This version is intended to be implemented by subclasses and so
raises a NotImplementedError.
- flush(self)
- Ensure all logging output has been flushed.
This version does nothing and is intended to be implemented by
subclasses.
- format(self, record)
- Format the specified record.
If a formatter is set, use it. Otherwise, use the default formatter
for the module.
- handle(self, record)
- Conditionally emit the specified logging record.
Emission depends on filters which may have been added to the handler.
Wrap the actual emission of the record with acquisition/release of
the I/O thread lock. Returns whether the filter passed the record for
emission.
- handleError(self, record)

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 record which was being processed is passed in to this method.
- release(self)
- Release the I/O thread lock.
- setFormatter(self, fmt)

- Add the specified filter to this handler.
- filter(self, record)
- 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.
- removeFilter(self, filter)
- Remove the specified filter from this handler.
|
class LogRecord |
| |
A LogRecord instance represents an event being logged.
LogRecord instances are created every time something is logged. They
contain all the information pertinent to the event being logged. The
main information passed in is in msg and args, which are combined
using str(msg) % args to create the message field of the record. The
record also includes information such as when the record was created,
the source line where the logging call was made, and any exception
information to be logged.
|
| |
Methods defined here:
- __init__(self, name, level, pathname, lineno, msg, args, exc_info)
- Initialize a logging record with interesting information.
- __str__(self)
- getMessage(self)
- Return the message for this LogRecord.
Return the message for this LogRecord after merging any user-supplied
arguments with the message.
|
class Logger(Filterer) |
| |
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.

Methods inherited from Filterer:
- addFilter(self, filter)
- Add the specified filter to this handler.
- filter(self, record)
- Determine if a record is loggable by consulting all the filters.

this and the record is then dropped. Returns a zero value if a record
is to be dropped, else non-zero.
- removeFilter(self, filter)
- Remove the specified filter from this handler.
