"""Exceptions for bzr, and reporting of them.
19
There are 3 different classes of error:
21
* KeyboardInterrupt, and OSError with EPIPE - the program terminates
22
with an appropriate short message
24
* User errors, indicating a problem caused by the user such as a bad URL.
25
These are printed in a short form.
27
* Internal unexpected errors, including most Python builtin errors
28
and some raised from inside bzr. These are printed with a full
29
traceback and an invitation to report the bug.
31
Exceptions are caught at a high level to report errors to the user, and
32
might also be caught inside the program. Therefore it needs to be
33
possible to convert them to a meaningful string, and also for them to be
34
interrogated by the program.
36
Exceptions are defined such that the arguments given to the constructor
37
are stored in the object as properties of the same name. When the
38
object is printed as a string, the doc string of the class is used as
39
a format string with the property dictionary available to it.
41
This means that exceptions can used like this:
45
... raise NotBranchError(path='/foo/bar')
47
... print '%s.%s' % (sys.exc_type.__module__, sys.exc_type.__name__)
48
... print sys.exc_value
49
... path = getattr(sys.exc_value, 'path', None)
50
... if path is not None:
52
bzrlib.errors.NotBranchError
53
Not a branch: /foo/bar
58
* create a new exception class for any class of error that can be
59
usefully distinguished. If no callers are likely to want to catch
60
one but not another, don't worry about them.
62
* the __str__ method should generate something useful; BzrError provides
63
a good default implementation
65
Exception strings should start with a capital letter and should not have a
69
