combination of handlers you choose.
.. _context-info:
Adding contextual information to your logging output
----------------------------------------------------
Sometimes you want logging output to contain contextual information in
addition to the parameters passed to the logging call. For example, in a
networked application, it may be desirable to log client-specific information
in the log (e.g. remote client's username, or IP address). Although you could
use the *extra* parameter to achieve this, it's not always convenient to pass
the information in this way. While it might be tempting to create
:class:`Logger` instances on a per-connection basis, this is not a good idea
because these instances are not garbage collected. While this is not a problem
in practice, when the number of :class:`Logger` instances is dependent on the
level of granularity you want to use in logging an application, it could
be hard to manage if the number of :class:`Logger` instances becomes
effectively unbounded.
There are a number of other ways you can pass contextual information to be
output along with logging event information.
* Use an adapter class which has access to the contextual information and
which defines methods :meth:`debug`, :meth:`info` etc. with the same
signatures as used by :class:`Logger`. You instantiate the adapter with a
name, which will be used to create an underlying :class:`Logger` with that
name. In each adpater method, the passed-in message is modified to include
whatever contextual information you want.
* Use something other than a string to pass the message. Although normally
the first argument to a logger method such as :meth:`debug`, :meth:`info`
etc. is usually a string, it can in fact be any object. This object is the
argument to a :func:`str()` call which is made, in
:meth:`LogRecord.getMessage`, to obtain the actual message string. You can
use this behavior to pass an instance which may be initialized with a
logging message, which redefines :meth:__str__ to return a modified version
of that message with the contextual information added.
* Use a specialized :class:`Formatter` subclass to add additional information
to the formatted output. The subclass could, for instance, merge some thread
local contextual information (or contextual information obtained in some
other way) with the output generated by the base :class:`Formatter`.
In each of these three approaches, thread locals can sometimes be a useful way
of passing contextual information without undue coupling between different
parts of your code.

Core and Builtins
-----------------
<<<<<<< .working
- Issue #1762972: __file__ points to the source file instead of the pyc/pyo
file if the py file exists.
=======
- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE envvar
and sys.dont_write_bytecode attribute. All these can be set to forbid Python
to attempt to write compiled bytecode files.
- Improve some exception messages when Windows fails to load an extension
module. Now we get for example '%1 is not a valid Win32 application' instead
of 'error code 193'.

of PyString.
<<<<<<< .working
=======
- Issue #1534: Added ``PyFloat_GetMax()``, ``PyFloat_GetMin()`` and
``PyFloat_GetInfo()`` to the float API.
- Issue #1521: On 64bit platforms, using PyArgs_ParseTuple with the t# of w#
format code incorrectly truncated the length to an int, even when
PY_SSIZE_T_CLEAN is set. The str.decode method used to return incorrect
results with huge strings.
- Issue #1402: Fix a crash on exit, when another thread is still running, and
if the deallocation of its frames somehow calls the PyGILState_Ensure() /
PyGILState_Release() functions.
- Expose the Py_Py3kWarningFlag as sys.py3kwarning.
- Issue #1445: Fix a SystemError when accessing the ``cell_contents``
attribute of an empty cell object.
- Issue #1460: The utf-7 incremental decoder did not accept truncated input.
It now correctly saves its state between chunks of data.
- Patch #1739468: Directories and zipfiles containing a __main__.py file can
now be directly executed by passing their name to the interpreter. The
directory/zipfile is automatically inserted as the first entry in sys.path.
- Issue #1265: Fix a problem with sys.settrace, if the tracing function uses a
generator expression when at the same time the executed code is closing a
paused generator.
- sets and frozensets now have an isdisjoint() method.
- optimize the performance of builtin.sum().
- Fix warnings found by the new version of the Coverity checker.
- The enumerate() builtin function is no longer bounded to sequences smaller
than LONG_MAX. Formerly, it raised an OverflowError. Now, automatically
shifts from ints to longs.
- Issue #1686386: Tuple's tp_repr did not take into account the possibility of
having a self-referential tuple, which is possible from C code. Nor did
object's tp_str consider that a type's tp_str could do something that could
lead to an inifinite recursion. Py_ReprEnter() and Py_EnterRecursiveCall(),
respectively, fixed the issues.
- Issue #1164: It was possible to trigger deadlock when using the 'print'
statement to write to a file since the GIL was not released as needed. Now
PyObject_Print() does the right thing along with various tp_print
implementations of the built-in types and those in the collections module.
- Issue #1147: Exceptions were directly allowing string exceptions in their
throw() method even though string exceptions no longer allowed.
- Issue #1096: Prevent a segfault from getting the repr of a very deeply nested
list by using the recursion counter.
- Issue #1202533: Fix infinite recursion calls triggered by calls to
PyObject_Call() never calling back out to Python code to trigger recursion
depth updates/checks. Required the creation of a static RuntimeError
instance in case normalizing an exception put the recursion check value past
its limit. Fixes crashers infinite_rec_(1|2|4|5).py.
- Patch #1031213: Decode source line in SyntaxErrors back to its original source
encoding.
- Py_ssize_t fields work in structmember when HAVE_LONG_LONG is not defined.
- PEP 3123: Provide forward compatibility with Python 3.0, while keeping
backwards compatibility. Add Py_Refcnt, Py_Type, Py_Size, and
PyVarObject_HEAD_INIT.
- Patch #1673759: add a missing overflow check when formatting floats
with %G.
- Patch #1733960: Allow T_LONGLONG to accept ints.
- T_PYSSIZET can now be used in PyMemberDef lists for Py_ssize_t members.
- Prevent expandtabs() on string and unicode objects from causing a segfault
when a large width is passed on 32-bit platforms.
- Bug #1733488: Fix compilation of bufferobject.c on AIX.
- Bug #1722485: remove docstrings again when running with -OO.
- Add new attribute names for function objects. All the func_* become
__*__ attributes. (Some already existed, e.g., __doc__ and __name__.)
- Add -3 option to the interpreter to warn about features that are
deprecated and will be changed/removed in Python 3.0.
- Patch #1686487: you can now pass any mapping after '**' in function
calls.
- except clauses may now be spelled either "except E, target:" or
"except E as target:". This is to provide forwards compatibility with
Python 3.0.
- Deprecate BaseException.message as per PEP 352.
- Bug #1303614: don't expose object's __dict__ when the dict is
inherited from a builtin base.
- When __slots__ are set to a unicode string, make it work the same as
setting a plain string, ie don't expand to single letter identifiers.
- Request #1191699: Slices can now be pickled.
- Request #1193128: str.translate() now allows a None argument for
translations that only remove characters without re-mapping the
remaining characters.
- Patch #1682205: a TypeError while unpacking an iterable is no longer
masked by a generic one with the message "unpack non-sequence".
- Remove unused file Python/fmod.c.
- Bug #1683368: The object.__init__() and object.__new__() methods are
now stricter in rejecting excess arguments. The only time when
either allows excess arguments is when it is not overridden and the
other one is. For backwards compatibility, when both are
overridden, it is a deprecation warning (for now; maybe a Py3k
warning later). Also, type.__init__() insists on the same signature
as supported by type.__new__().
- Patch #1675423: PyComplex_AsCComplex() now tries to convert an object
to complex using its __complex__() method before falling back to the
__float__() method. Therefore, the functions in the cmath module now
can operate on objects that define a __complex__() method.
- Patch #1623563: allow __class__ assignment for classes with __slots__.
The old and the new class are still required to have the same slot names.
- Patch #1642547: Fix an error/crash when encountering syntax errors in
complex if statements.
- Patch #1462488: Python no longer segfaults when ``object.__reduce_ex__()``
is called with an object that is faking its type.
- Patch #1680015: Don't modify __slots__ tuple if it contains an unicode
name.
- Patch #1444529: the builtin compile() now accepts keyword arguments.
- Bug #1678647: write a newline after printing an exception in any
case, even when converting the value to a string failed.
- The dir() function has been extended to call the __dir__() method on
its argument, if it exists. If not, it will work like before. This allows
customizing the output of dir() in the presence of a __getattr__().
- Patch #922167: Python no longer segfaults when faced with infinitely
self-recursive reload() calls (as reported by bug #742342).
- Patch #1675981: remove unreachable code from ``type.__new__()`` method.
- Patch #1491866: change the complex() constructor to allow parthensized
forms. This means complex(repr(x)) now works instead of raising a
ValueError.
- Patch #703779: unset __file__ in __main__ after running a file. This
makes the filenames the warning module prints much more sensible when
a PYTHONSTARTUP file is used.
- Variant of patch #697613: don't exit the interpreter on a SystemExit
exception if the -i command line option or PYTHONINSPECT environment
variable is given, but break into the interactive interpreter just like
on other exceptions or normal program exit.
- Patch #1638879: don't accept strings with embedded NUL bytes in long().
- Bug #1674503: close the file opened by execfile() in an error condition.
- Patch #1674228: when assigning a slice (old-style), check for the
sq_ass_slice instead of the sq_slice slot.
- When printing an unraisable error, don't print exceptions. before the name.
This duplicates the behavior whening normally printing exceptions.
- Bug #1653736: Properly discard third argument to slot_nb_inplace_power.
- PEP 352: Raising a string exception now triggers a TypeError. Attempting to
catch a string exception raises DeprecationWarning.
- Bug #1377858: Fix the segfaulting of the interpreter when an object created
a weakref on itself during a __del__ call for new-style classes (classic
classes still have the bug).
- Bug #1579370: Make PyTraceBack_Here use the current thread, not the
frame's thread state.
- patch #1630975: Fix crash when replacing sys.stdout in sitecustomize.py
- Bug #1637022: Prefix AST symbols with _Py_.
- Prevent seg fault on shutdown which could occur if an object
raised a warning.
- Bug #1566280: Explicitly invoke threading._shutdown from Py_Main,
to avoid relying on atexit.
- Bug #1590891: random.randrange don't return correct value for big number
- Patch #1586791: Better exception messages for some operations on strings,
tuples and lists.
- Bug #1067760: Deprecate passing floats to file.seek.
- Bug #1591996: Correctly forward exception in instance_contains().
- Bug #1588287: fix invalid assertion for `1,2` in debug builds.
- Bug #1576657: when setting a KeyError for a tuple key, make sure that
the tuple isn't used as the "exception arguments tuple".
- Bug #1565514, SystemError not raised on too many nested blocks.
- Bug #1576174: WindowsError now displays the windows error code
again, no longer the posix error code.
- Patch #1549049: Support long values in structmember, issue warnings
if the assigned value for structmember fields gets truncated.
- Update the peephole optimizer to remove more dead code (jumps after returns)
and inline unconditional jumps to returns.
- Bug #1545497: when given an explicit base, int() did ignore NULs
embedded in the string to convert.
- Bug #1569998: break inside a try statement (outside a loop) is now
recognized and rejected.
- list.pop(x) accepts any object x following the __index__ protocol.
- Fix some leftovers from the conversion from int to Py_ssize_t
(relevant to strings and sequences of more than 2**31 items).
- A number of places, including integer negation and absolute value,
were fixed to not rely on undefined behaviour of the C compiler
anymore.
- Bug #1566800: make sure that EnvironmentError can be called with any
number of arguments, as was the case in Python 2.4.
- Patch #1567691: super() and new.instancemethod() now don't accept
keyword arguments any more (previously they accepted them, but didn't
use them).
- Fix a bug in the parser's future statement handling that led to "with"
not being recognized as a keyword after, e.g., this statement:
from __future__ import division, with_statement
- Bug #1557232: fix seg fault with def f((((x)))) and def f(((x),)).
- Fix %zd string formatting on Mac OS X so it prints negative numbers.
- Allow exception instances to be directly sliced again.
- Bug #1551432: Exceptions do not define an explicit __unicode__ method. This
allows calling unicode() on exceptions classes directly to succeed.
- Make _PyGILState_NoteThreadState() static, it was not used anywhere
outside of pystate.c and should not be necessary.
- Bug #1542051: Exceptions now correctly call PyObject_GC_UnTrack.
Also make sure that every exception class has __module__ set to
'exceptions'.
- Bug #1550983: emit better error messages for erroneous relative
imports (if not in package and if beyond toplevel package).
- Overflow checking code in integer division ran afoul of new gcc
optimizations. Changed to be more standard-conforming.
- Patch #1542451: disallow continue anywhere under a finally.
- Patch #1546288: fix seg fault in dict_equal due to ref counting bug.
- The return tuple from str.rpartition(sep) is (tail, sep, head) where
head is the original string if sep was not found.
- Bug #1520864: unpacking singleton tuples in list comprehensions and
generator expressions (x for x, in ... ) works again. Fixing this problem
required changing the .pyc magic number. This means that .pyc files
generated before 2.5c2 will be regenerated.
- with and as are now keywords.
- Bug #1664966: Fix crash in exec if Unicode filename can't be decoded.
- Issue #1537: Changed GeneratorExit's base class from Exception to BaseException.

lack of an infinite recursion check.
- Removed plat-freebsd2 and plat-freebsd3 directories (and IN.py in
the directories).
- HTML-escape the plain traceback in cgitb's HTML output, to prevent
the traceback inadvertently or maliciously closing the comment and
injecting HTML into the error page.

(as opposed to the command line) will now write file names ending in
".cpp" too.

AttributeError instead of an IOError when the server's response didn't
contain a valid HTTP status line.
- Patch #957650: "%var%" environment variable references are now properly
expanded in ntpath.expandvars(), also "~user" home directory references
are recognized and handled on Windows.

the debugged script, which means that imports from __main__ work
correctly now.

Python program, optionally with different arguments.
- Patch #1649190: Adding support for _Bool to ctypes as c_bool.
- Patch #1530482: add pydoc.render_doc() which returns the documentation
for a thing instead of paging it to stdout, which pydoc.doc() does.
- Patch #1533909: the timeit module now accepts callables in addition to
strings for the code to time and the setup code. Also added two
convenience functions for instantiating a Timer and calling its methods.

which can be set to False to prevent the default delete-on-close
behavior.
- Patch #1581073: add a flag to textwrap that prevents the dropping of
whitespace while wrapping.
- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
are set for invalid interpolation sequences that would lead to errors
on reading back those values.

field names in its exception message if you try to write a record with
a dictionary containing fields not in the CSV field names list.

OSError if accessing a local file via the file:// protocol fails.
- Patch #1677862: Require a space or tab after import in .pth files.

and server_activate() in the constructors for TCPServer, SimpleXMLRPCServer
and DocXMLRPCServer.
- Bug #1531963: Make SocketServer.TCPServer's server_address always
be equal to calling getsockname() on the server's socket. Fixed by
patch #1545011.
- Bug #1651235: When a tuple was passed to a ctypes function call,

The KeyError raised by Zipfile.getinfo for nonexistent names now has
a descriptive message.
- Bug #1115886: os.path.splitext('.cshrc') gives now ('.cshrc', '').
- unittest now verifies more of its assumptions. In particular, TestCase
and TestSuite subclasses (not instances) are no longer accepted in
TestSuite.addTest(). This should cause no incompatibility since it
never made sense with ordinary subclasses -- the failure just occurred
later, with a more cumbersome exception.
- Patch #787789: allow to pass custom TestRunner instances to unittest's
main() function.
- Patches #1550273, #1550272: fix a few bugs in unittest and add a

subprocess.
- Patch #1634778: add missing encoding aliases for iso8859_15 and
iso8859_16.

- The sets module has been deprecated. Use the built-in set/frozenset types
instead.
- Bug #1610795: make ctypes.util.find_library work on BSD systems.
- Fixes for 64-bit Windows: In ctypes.wintypes, correct the
definitions of HANDLE, WPARAM, LPARAM data types. Make
parameterless foreign function calls work.
- The version number of the ctypes package changed to "1.1.0".
- Bug #1627575: logging: Added _open() method to FileHandler which can
be used to reopen files. The FileHandler instance now saves the
encoding (which can be None) in an attribute called "encoding".

being raised when print_exc() was called without an exception set.
In version 2.4, this printed "None", restored that behavior.

first chunk fed to the decoder started with a BOM, but was longer than 3 bytes.
- The implementation of UnicodeError objects has been simplified (start and end
attributes are now stored directly as Py_ssize_t members).
