0.41dev

Wed May 29, 2013

  • command plugins are not to be prefixed with Command. This is because plugins are now referred by their canonical names.
  • mainargs() function added to gather main-script parameters from command line. Remaining parameters will be passed on to the sub-commands.
  • Added a query_pluginr() method similar to query_plugins() method, except that it accepts an additional pattern argument that will be matched with plugin’s canonical-names. Only matching plugins will be instantiated and returned as a list. query_pluginr() method is aliased as qpr()
  • Sphinx documentation style. min-width of <body> tag is adjusted to 970px.
  • Removed IHTTPRenderer interface from pluggdapps.web.interfaces module, instead a similar interface ITemplate is added to pluggdapps.interfaces module. IHTTPResponse plugins are expected to use this new interface.
  • webapp command/scaffold is renamed to newwebapp.
  • Added a script bin/relchk.sh to check pre and post releases of pluggdapps package.

0.4dev

Tue May 21, 2013

  • scaffold source files must not end with .py, as python module, this will throw errors while installing them via pip. To solve this problem, .py files are suffixed with .tmpl, and utils.scaff module will remove the suffix before creating the scaffold logic in target directory.
  • Sub command confdoc is added to automatically generate a catalog of configuration settings for plugins in pluggdapps, or any other, package.
  • A new alias for query_plugin(), as qp(), and query_plugins(), as qps() is now available.
  • Cleaned up and refactored platform boot sequence.
    • First all pluggdapps-packages are gathered from the environment.
    • Then gathered packages are loaded.
    • And during platform boot-time, package entry-point is called.
  • added namespace for plugins. Every plugin name can be queried and accessed by prefixing its class-name with package name. This is not the canonical form for plugin-names. For example, plugin ConfigSqlite3DB defined in pluggdapps package is to be accessed as, pluggdapps.ConfigSqlite3DB.
  • Every instantiated plugin will now have a caname attribute that provides the canonical name of the plugin. This is automatically populated by component-arch during plugin instantiation.
  • query_plugin() and query_plugins() method calls now supports interface argument as string of interface-name, specified in canonical-form.
  • plugincall(), pluginname() function is removed and canonical_name() function is added in pluggdapps.plugin module. Note that canonical_name() function is meant to be called only by logic inside PluginMeta class.
  • pluggdapps.initialize() is now pluggdapps.callpackages().
  • platform.Pluggdapps class has _preboot() local method to handle pre-booting logic.
  • Moved sphinx-documentation to docs/ directory. It is more work to manage two separate versions of documentation. All articles under docs/ directory are active and publishable, while documentation that are more specific to internals of pluggdapps are under docs/dev/ directory.

0.3dev

Tue Mar 12, 2013

  • Live debug. Interactive debugging to catch exception and introspect stack frame via web.
  • WebAdmin configuration application.
  • ConfigSQlite3DB plugin for storing configuration settings in sqlite3 database.
  • CatchAndDebug plugin re-writes tracebacks involving template tracebacks to accurately point mis-behaving template text.

  • routemapper configuration to add_views() is now handled by matchrouter plugin.
  • HTTP content negotiation abstracted into IHTTPNegotiator interface and plugin by name httpnegotiator is supplied for matchrouter.
  • match_predicates() method added while resolving view-callables. Right now a request resolution to view-callable follows three steps.
    • URL pattern matching
    • match_predicates on add_view arguments and request.
    • Content_negotiation to pick a resource-variant.
  • Order of calls to add_view() method is preserved while resolving request to view-callable.
  • added platform pre-booting feature.
    • First load all pluggdapps packages to create a Pluggdapss() platform, then call package() entry point in all pluggdapps packages and finally create the platform.
    • package loading during platform pre-booting should happen after all relevant pluggdapps modules are imported in __init__.py
    • Package loading during pluggdapps platform pre-boot is now handled by an explicit call to pluggdapps.loadpackages() function.
  • pluggdapps project static files - logos and css files.
  • Documentation for configuration help.
  • Gathering files for reloading is now moved to Serve sub-command plugin, instead of handling it in platform classes.
  • Improved interactive excaption handling in errorpage.ttl (WebAdmin plugin).
  • WebAdmin configuration app is more or less functional.
  • package() entry-point now can return ‘ttlplugins’ info.
  • Automatic server restart now monitors .ini files and .ttl files as well.
  • request.getparams and request.postparams now provide key,value pairs as string.
  • Added view callable for serving static files for an application.
