Move files out of the namespace package
Move the public API out of oslo.utils to oslo_utils. Retain the ability to import from the old namespace package for backwards compatibility for this release cycle. bp/drop-namespace-packages Change-Id: Ic6dd62097399bf75e3d11b4d8a6400971069c415

To use oslo.utils in a project, import the individual module you

need. For example::

from oslo.utils import strutils

from oslo_utils import strutils

In some cases the exception context can be cleared, resulting in None

|

|

In some cases the exception context can be cleared, resulting in None
|

being attempted to be re-raised after an exception handler is run. This
|
||||
can happen when eventlet switches greenthreads or when running an
|
||||
exception handler, code raises and catches an exception. In both
|
||||
cases the exception context will be cleared.
|
||||
|
||||
To work around this, we save the exception state, run handler code, and
|
||||
then re-raise the original exception. If another exception occurs, the
|
||||
saved exception is logged and the new exception is re-raised.
|
||||
|
||||
In some cases the caller may not want to re-raise the exception, and

for those circumstances this context provides a reraise flag that

decide_if_need_reraise()

|
||||
|
||||
If another exception occurs and reraise flag is False,
|
||||
the saved exception will not be logged.
|
||||
|
||||
If the caller wants to raise new exception during exception handling
|
||||
he/she sets reraise to False initially with an ability to set it back to
|
||||
True if needed::
|
||||
|
