logtool
=======
Methods and tools that assist logging. Can be installed from PyPI:
::
$ pip install logtool
log\_call
---------
A decorator for function and method definitions that logs at DEBUG
level a variety of data about every call made to that entrypoint.
Intended to supercede @log_func and log_func_noargs (see below). See
log\_func for example output.
Optional arguments:
log\_enter
Log entrance to the decorated method. Defaults to True.
log\_args
Log the arguments passed to the decorated method. Defaults to True.
log\_exit
Log exit/returns from the decorated method along with the execution time. Defaults to True.
log\_rc
Log the value returned by the decorated method. Defaults to True.
log\_trace
Log each line of the decorated method as it is executed. Defaults to False.
log\_level
Log level to use for the logging of the call. Defaults to logging.DBEUG.
::
@logtool.log_call
def a_method (...):
...etc...
::
@logtool.log_call (log_args = False, log_rc = False)
def big_complex_data (...):
...etc...
log\_func
---------
A decorator for function and method definitions that logs at DEBUG level
every call to that function or method along with its arguments.
eg
::
@logtool.log_wrap
def my_method (self, *args):
...stuff here...
Resulting log entry from a real production usage (with a few of the
argumentvalues redacted):
::
Entered: function:test_tool.toolwrapper:email_report ((<test_tool.meshtool.Wrapper object at 0x7f19d4879c10>, path(u'../file.ext'), 'address@domain.com', 'address@domain.com', 'Interesting subject header') {})
The {} at the end shows that there were no named arguments passed to
that call, else they would be shown there.
log\_func\_noargs
-----------------
A decorator for function and method definitions that logs at DEBUG level
every call to that function or method but without any arguments. This
can be useful when traversing and dumping the arguments would be
execssively expensive, or would potentially create infinite loops.
eg
::
@logtool.log_wrap_noargs
def my_method (self, *args):
...stuff here...
log\_fault
----------
Logs an exception in a standardised form, including the source file and
line number of the exception, and if logging at DEBUG level, also logs a
stack trace along with all the variables in each stack frame. eg
In WARN or higher mode:
::
CRITICAL <log_fault_impl:log_fault(24)> FAULT: /usr/local/lib/python2.7/dist-packages/workerd-0.1.26_gbb342e2-py2.7.egg/workerd/do.py(243): IOError(28, 'No space left on device')
When logging at DEBUG:
::
CRITICAL <log_fault_impl:log_fault(24)> FAULT: /usr/local/lib/python2.7/dist-packages/workerd-0.1.26_gbb342e2-py2.7.egg/workerd/do.py(243): IOError(28, 'No space left on device')

DEBUG <log_fault_impl:log_fault(40)> fn = /var/spool/matterport/workerd/generate_mesh/d34fea
time\_str
---------
Simply returns a time\_t (seconds since the epoch, possibly fractional)
in a simple consistent string form suitable for logfiles, reports and
the like.
See below under ``now`` for an example.
now
---
Reurns a tuple of the current time as a time\_t, and its matching
time\_str. Getting the two together allows the string to be used for
logs and the like, and the time_t to be used as a numeric. eg:
