Fixes and Enhancements since Version 0.5 alpha 1 |
| |
|
| |
Changed, Enhanced, or Newly Deprecated Features |
| |
|
| |
- The signatures of the 'getObjectInstance()', 'getStateToBind()', and |
| |
'getURLContext()' methods in the 'peak.naming' package have changed, to |
| |
place the context or parent component as the first, non-optional argument. |
| |
(If you don't know what these methods are for, you don't need to do anything |
| |
about this, as they are part of the naming package's extensibility |
| |
framework.) |
| |
|
| |
- 'EigenRegistry' and 'PropertyMap' no longer attempt to figure out whether |
| |
implied (i.e. inherited) interfaces are more or less general with respect |
| |
to a previous registration. This was behavior that emulated Zope adapter |
| |
registries, but what we really wanted was more akin to a Zope "type" |
| |
registry. The only parts of the test suite that used the old behavior |
| |
were the tests specifically written to ensure that behavior! |
| |
|
| |
- 'binding.bindTo()' now accepts a 'default=' argument, whose value will be |
| |
used in case of a 'NameNotFound' error. |
| |

modules) that can be used in place of the old regex-based approach. |
| |
|
| |
- Added 'peak.util.fmtparse', a parsing and formatting framework, and |
| |
integrated it with 'peak.model' so that any element type can have a |
| |
syntax for parsing from, or formatting to, a string. |
| |

- Made 'NOT_GIVEN' and 'NOT_FOUND' recognizable by humans (they 'repr' |
| |
and 'str' to their names) and by Python (they can be pickled, and |
| |
when restored they come back as the same object). |
| |
|
| |
|
| |
Corrected Problems |
| |
|
| |
- Fixed 'naming.lookup()' and related APIs not setting the parent component |
| |
of created objects without an explicitly supplied 'creationParent' keyword |
| |
argument. This used to "sort of work" when we had implicit configuration |
| |
parents, but was broken when we went "all explicit" for 0.5 alpha 1. |
| |
|
| |
- Fixed a problem where initializing single-valued immutable fields of |
| |
'peak.model' types did not perform type/value normalization. |
| |
|
| |
- Fixed a problem where bindTo would use the attribute name as the |
| |
default value for a lookup, if the requested name/property/utility |
| |
was not found. |
