Fixes and Enhancements since Version 0.5 alpha 3 |
| |
|
| |
- Added Zope 3-like "namespaces" to 'peak.web'. Path segments in a URL |
| |
may be prefixed with '"++some_id++"' in order to invoke a corresponding |
| |
namespace handler registered under '"peak.web.namespaces.some_id". |
| |
Namespace handlers must implement 'web.INamespaceHandler', and they are |
| |
supplied with the original path segment as well as the separated namespace |
| |
and name. Also, as in Zope 3, '"@@foo"' is a shortcut for '"++view++foo"'. |
| |
Builtin namespaces at this time include 'view', 'item', 'attr', 'skin', and |
| |
'resources'. 'skin' treats the rest of its path segment as a skin name, |
| |
and sets the current skin, and 'resources' begins traversal to resources |
| |
found in the current skin. The other namespaces are as described at: |
| |
|
| |
"Resources and traversal in peak.web":http://www.eby-sarna.com/pipermail/peak/2004-August/001712.html |

- Fixed several 'peak.events' bugs, as reported by Vladimir Iliev, Yaroslav |
| |
Samchuk, and Alexander Smishlajev: |
| |
|
| |
* 'events.AnyOf' could hold multiple references to a single event source, |
| |
and nesting 'AnyOf()' calls could leak references to the nested events. |
| |
|
| |
* 'events.subscribe()' had a potential race condition wherein a callback |
| |
could be invoked after its weak reference was garbage collected, leading |
| |
to bizarre error messages about 'self' being 'None'. |
| |
|
| |
* 'select()' could be called on select event objects even if there were |
| |
no current subscribers to the event, potentially leading to calling |
| |
'select()' on a closed socket. |
| |
|
| |
* Non-default signal handlers were remaining installed even when there |
| |
were no current subscribers to the applicable event, as long as a |
| |
reference to the event object existed. |
| |
|
| |
As a result of these changes, certain I/O event types (esp. signals and |
| |
stream readable/writeable events) are now longer-lived. For example, |
| |
signal event objects are now immortal, and the read/write event for a |
| |
particular 'fileno()' will be reused for as long as its supplying |
| |
'Selector' or 'EventLoop' instance exists. (Previously, weak references |
| |
were used so that these objects would be recycled when not in use.) |
| |
|
| |
- Added 'config.registeredProtocol()' API, that supports defining named and |
| |
local protocols. This allows easy emulation of Zope 3's "named" and "local" |
| |
adapters and views. |
| |
|
| |
- 'binding.Component' objects no longer support instance configuration at |
| |
runtime (i.e., they no longer implement 'config.IConfigurable'). If you |
| |
need a component to be configurable at runtime, you must now derive from |
| |
(or mix in) 'binding.Configurable' instead. If you get errors about |
| |
a missing 'registerProvider' attribute, or about being unable to adapt to |
| |
'IConfigurable', try changing your base class from 'binding.Component' |
| |
to 'binding.Configurable', or add it as a mixin if you're deriving from |
| |
a class that uses 'binding.Component' as its base. |
| |
|
| |
- 'binding.IComponent' no longer derives from 'config.IConfigurable' or |
| |
'config.IConfigMap', only 'config.IConfigSource'. This means that |
| |
'IComponent' no longer guarantees or requires the presence of the |
| |
'registerProvider()' method: now only 'config.IConfigurable' does that. |
| |
|
| |
- The 'config.IConfigMap' interface is now DEPRECATED. Use |
| |
'config.IConfigurable' instead. The '_configKeysMatching()' method |
| |
of 'IConfigMap' was moved to 'config.IConfigSource', so if you've |
| |
implemented a custom 'IConfigSource', be sure to add this method. |
| |
|
| |
- 'web.ISkinService' and 'web.ILayerService' were consolidated into |
| |
'web.IInteractionPolicy', because the need to have configurable |
| |
implementations of these services is negligible. That is, the |
| |
corresponding property namespaces ('peak.web.skins' and 'peak.web.layers') |
| |
are more than adequate as registries. |
| |
