"""Exceptions for bzr, and reporting of them.
18
19
Exceptions are caught at a high level to report errors to the user, and
20
might also be caught inside the program.  Therefore it needs to be
21
possible to convert them to a meaningful string, and also for them to be
22
interrogated by the program.
23
24
Exceptions are defined such that the arguments given to the constructor
25
are stored in the object as properties of the same name.  When the
26
object is printed as a string, the doc string of the class is used as
27
a format string with the property dictionary available to it.
28
29
This means that exceptions can used like this:
30
31
>>> import sys
32
>>> try:
33
...   raise NotBranchError(path='/foo/bar')
34
... except:
35
...   print sys.exc_type
36
...   print sys.exc_value
1551.6.23 by Aaron Bentley
Added None to getattr for case where error doesn't has have path
37
...   path = getattr(sys.exc_value, 'path', None)
1185.50.38 by John Arbash Meinel
Changed exception traceback route to not use hasattr, which generates its own exception.
38
...   if path is not None:
39
...     print path
