Fixes and Enhancements since Version 0.5 alpha 2 |
| |
|
| |
Changed, Enhanced, or Newly Deprecated Features |
| |
|
| |
- It's no longer necessary to provide a '_defaultState()' implementation |
| |
for an EntityDM: a default implementation is now supplied. |
| |
|
| |
- Added automatic installation of 'datetime' package for Python < 2.3. |
| |
|
| |
- CGI support has been moved from 'peak.running.zpublish' into |
| |
'peak.running.commands' (for "raw" CGI/FastCGI) and 'peak.web' (for the |
| |
PEAK high-level publishing framework). You can use 'peak CGI someName' to |
| |
adapt 'someName' to a 'running.IRerunnableCGI' and run it as a CGI/FastCGI. |
| |
|
| |
- There is now a 'peak.security' package, available from 'peak.api' as |
| |
'security'. It provides permission management functions: you can define |
| |
abstract permissions by subclassing 'security.Permission', then create |
| |
permission checking rules by subclassing 'security.RuleSet', and declare |
| |
the permissions needed to access attributes of a class with |
| |
'security.allow()'. The test suite demonstrates a complex application |
| |
ruleset with dynamic, data-driven permissions. |
| |
|
| |
- There is now an interface for "Active Descriptors": |
| |
'binding.IActiveDescriptor'. 'peak.binding' now uses this interface to |
| |
identify active descriptors, so you can now create your own. (Previously, |
| |
'peak.binding' used 'isinstance()' to detect active descriptors.) |
| |
|
| |
- 'peak.naming' no longer automatically converts all addresses to the |
| |
addressed objects. You must specifically request the interface you want |
| |
by adapting the retrieved object to that interface. This can be done by |
| |
supplying an 'adaptTo=ISomething' keyword argument to the attribute binding |
| |
definition or your 'lookupComponent()' call. |
| |
|
| |
The naming system no longer has 'objectFactories' and 'stateFactories'; |
| |
these have been replaced with adaptation. Writable naming contexts must |
| |
have a 'serializationProtocol' attribute specifying what interface an object |
| |
should be adapted to before attempting to store it in that context. |
| |
|
| |
The naming system no longer processes the 'creationName' keyword argument; |
| |
this is now considered the sole responsibility of 'peak.binding'. The |
| |
'IComponent.lookupComponent()' method still accepts the keyword argument, |
| |
and attribute bindings still handle the creation name transparently. It is |
| |
just not available via naming system APIs, and naming contexts no longer |
| |
have to deal with it. |
| |
|
| |
The naming system base classes no longer use 'attrs' as an input parameter |
| |
or return value. If you've subclassed anything from 'peak.naming.contexts', |
| |
note that your '_get()' methods should now just return the lookup value, |
| |
rather than a 'state,attrs' tuple. For most naming contexts, this just |
| |
means you should change 'return foo, None' statements to just 'return foo'. |
| |
|
| |
- REMOVED 'naming.ParsedURL'; it was deprecated as of 0.5 alpha 2. |
| |
|
| |
- The 'provides' keyword argument to various 'peak.binding' APIs has been |
| |
renamed to 'offerAs', and it must be a sequence of configuration keys. |
| |
(Previously, it accepted either a single key or a tuple of keys.) |
| |
The signature of 'binding.Constant()' was changed as well; the first |
| |
positional argument is now the constant value, and 'offerAs' is now a |
| |
keyword argument. (Previously, 'provides' was the first positional argument |
| |
of 'binding.Constant()'.) The 'registerProvider()' method of |
| |
'config.IConfigurable()' also now accepts only a single configuration key, |
| |
as does 'EigenRegistry.register()'. |
| |
|
| |
Also, all 'peak.binding' APIs now only accept positional parameters for |
| |
items unique to that API. Items common to multiple APIs (such as 'offerAs', |
| |
'doc', 'attrName', etc.) should now be supplied as keyword arguments. |
| |
|
| |
Bindings also now automatically "suggest" the containing object as a parent |
| |
component for the contained object, whenever a value is assigned to them or |
| |
computed. If a non-None 'adaptTo' is set on the binding, the value assigned |
| |
or computed will be adapted to the specified protocol before the parent |
| |
component is suggested. 'binding.New()' no longer relies on the |
| |
'IComponentFactory' interface, but instead uses the new adapt/suggest |
| |
mechanisms. |
| |
|
| |
Previously, parent components were only "suggested" when a binding was set |
| |
via component constructor keyword arguments. Now, this is done at any time |
| |
bindings are set, but *not* for non-binding keyword arguments. In other |
| |
words, ordinary attributes of a component do not receive "suggested parent" |
| |
notices, even when set via constructor keyword arguments. If you want an |
| |
attribute to do this, you must define the attribute with the binding API; |
| |
e.g. via 'requireBinding()' or 'binding.Constant()'. If you do *not* want |
| |
a binding to suggest a parent component, use 'suggestParent=False' in the |
| |
binding definition. |

|
| Changed, Enhanced, or Newly Deprecated Features |
Changed, Enhanced, or Newly Deprecated Features |
| |
|
| |
- Added a 'shellcmd:' URL scheme that returns a function that calls |
| |
'os.system()' on the body of the URL. It's intended for use as a command |
| |
factory, as is needed by the 'URLChecker' periodic task. |
| |
|
| |
- You can now define adapters from arbitrary types to 'binding.IBindingNode', |
| |
and thus be able to use them as part of a component hierarchy - without |
| |
needing to directly add 'getParentComponent()' or 'getComponentName()' |
| |
methods to them. |
| |
|
| |
- Added experimental 'invoke.c' script for POSIX-ish platforms with funky |
| |
'#!' support, or lack thereof. |
| |
|
| |
'invoke' is designed to be used like this:: |
| |
|
| |
#!/usr/local/bin/invoke peak somearg otherarg... |
| |
|
| |
This should work on most sane platforms with a long-enough commandline. |
| |
(See "this page":http://homepages.cwi.nl/~aeb/std/hashexclam-1.html for |
| |
details on the insanely incompatible ways different Unixes interpret '#!' |
| |
lines.) |
| |
|
| |
The script is not currently built or installed by setup.py. On the |
| |
platforms it's targeted at, you should be able to build it with:: |
| |
|
| |
gcc -o invoke invoke.c |
| |
|
| |
(Yes, it really is that simple of a script.) |
| |
|
| |
- Added a ZConfig schema for 'running.commands.EventDriven' applications, |
| |
a ZConfig component definition for adaptive tasks, and a running shortcut |
| |
called 'EventDriven'. |
| |
|
| |
It should now be possible to do this:: |
| |
|
| |
#!/usr/bin/env peak EventDriven |
| |
|
| |
at the top of a ZConfig file formatted according to the new schema, and |
| |
have it run. There are two periodic tasks that can be configured and |
| |
run from such a file: 'CleanupFiles' and 'URLChecker'. 'CleanupFiles' will |
| |
delete files matching a pattern that are older than a certain age, while |
| |
'URLChecker' will check to see if the target of a naming system URL is |
| |
up/available/working, and if not, runs a command to restart it. As an |
| |
amusing demo, try specifying a 'file:' URL with a 'shellcmd:touch theFile' |
| |
to recreate the file, then add a 'CleanupFiles' that deletes the file the |
| |
checker looks for. This can be hours (well, minutes) of exciting fun as you |
| |
watch the dueling daemons undoing each others' work. |
| |
|
| |
- Added 'zconfig.schema' URL scheme that loads an enhanced ZConfig schema |
| |
object that can act as a command line interpreter using the 'peak' script. |
| |
|
| |
To use it, run 'peak zconfig.schema:urlToSchema urlOfConfig'. Or, add |
| |
a line like this:: |
| |
|
| |
#!/usr/bin/env peak zconfig.schema:pkgfile:some.package/schema.xml |
| |
|
| |
to the top of a configuration file, and make the configuration file |
| |
executable. Note that the schema specified must convert to an object |
| |
that's usable with the commands bootstrap framework. Also note that |
| |
if you have a local PEAK_CONFIG file, you can add a 'peak.running.shortcuts' |
| |
entry to shorten the URL reference in your #! line. E.g.:: |
| |
|
| |
#!/usr/bin/env peak mySchema |
| |
|
| |
will suffice if you have defined 'peak.running.shortcuts.mySchema' as |
| |
'naming.LinkRef("zconfig.schema:pkgfile:some.package/schema.xml")'. |
| |
|
| |
There is also a 'peak ZConfig urlOfSchema urlOfConfig' variant, that was |
| |
added to support putting '#!/usr/bin/env peak ZConfig' at the top of |
| |
schema files, but unfortunately that's not valid XML. |
| |
|
| |
- Standardized file-based URL syntaxes (e.g logfiles and lockfiles) to |
| |
follow RFC 1738/2396, and Python 'urllib'. This shouldn't affect much |
| |
besides the canonical forms of the URLs. Added 'pkgfile:some.pkg/filepath' |
| |
URL syntax for ease of referring to files near modules. (A convenience |
| |
intended mainly for referencing ZConfig schemas.) |
| |
|

when loading from XMI. Also, mof2py no longer emits 'config.setupModule()' |
| |
calls in generated code, as in practice they are not needed. |
| |
|
| |
- Running 'peak test' from the command line is roughly equivalent to running |
| |
'unittest.py', except that the test suite defaults to the PEAK test suite. |
| |
You can, however run any test suite from the command line with a dotted |
| |
module/attribute path, e.g 'peak test foo.bar.test_suite'. |
| |
|

| |
|
| - '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! |

- Fixed a problem with 'binding.supertype()' not working correctly if the MRO |
