- 'config.Namespace()' objects now have a 'keys()' method that can be used |
| |
when the namespace is bound to a context component. It returns a list of |
| |
strings that may be used as keys for that namespace. Example usage:: |
| |
|
| |
>>> from peak.api import * |
| |
>>> r=config.makeRoot() |
| |
>>> ns=config.Namespace('peak.naming.schemes',r) |
| |
>>> ns.keys() |
| |
['https', 'smtp', 'logfile', 'psycopg', 'pkgfile', 'unix.dg', 'win32.dde', |
| |
'sybase', 'timer', 'lockfile', 'pgsql', 'fd.socket', 'uuid', 'tcp', 'file', |
| |
'gadfly', 'http', 'logger', 'icb', 'cxoracle', 'udp', 'winflockfile', |
| |
'import', 'logging.logger', 'nulllockfile', 'nis', 'shlockfile', |
| |
'zconfig.schema', 'flockfile', 'shellcmd', 'dcoracle2', 'config', 'ftp', |
| |
'unix', 'ldap', 'sqlite', 'mockdb'] |
| |
>>> ns['ldap'] |

'peak.storage.LDAP:ldapURL' |

- Log events don't use a positional 'message' argument any more, and |
| |
loggers aren't responsible for interpolating message arguments any more. |
| |
The new signature is 'Event(parent, msg=msg, args=args, ...)'. Loggers |
| |
also now tell events what logger name they are, via the 'ident' keyword. |
| |
|
| |
- The logging system now uses a property namespace, 'peak.logging.levels', to |
| |
obtain log level names and values. The various 'logs.LEVEL' constants are |
| |
now DEPRECATED. Please use the 'getLevelFor()' method of the nearest |
| |
'logs.ILoggingService' instead. Also note that URL schemes such as |
| |
'logfile:' no longer convert their level names to numbers, since the |
| |
level names are only meaningful in the context of a logging service. |
| |
|
| |
- Support for integration with the Python 2.3/PEP 282 logging module has been |
| |
scaled back. There are too many globalisms and dependencies there. When we |
| |
add plugin-based log configuration, it should be possible to use the logging |
| |
package's handlers and formatters with the PEAK logging services. At that |
| |
point, you'll be able to replace 'logging.getLogger' and |
| |
'logging.getLevelName' with the corresponding methods of a PEAK logging |
| |
service, if you need to force non-PEAK packages to use PEAK's logging. |
| |
|
| |
- Logs are now accessed via a 'logs.ILoggingService' instance. The 'logger:' |
| |
URL scheme automatically accesses the nearest such service. For backward |
| |
compatibility, the old 'peak.logs' namespace is still used to supply the |
| |
actual loggers. This will be gradually replaced with a plugin-based |
| |
mechanism. |
