Fixes and Enhancements since Version 0.5 alpha 3 |
| |
|
| - Added 'ref:factory@addr' URL scheme that maps to a corresponding |
- The 'log()' method of PEAK loggers ('logs.ILogger') now accepts a level name |
| 'naming.Reference("factory",["addr"])'. 'factory' can be either a dotted |
*or* a number, for convenient invocation. |
| import string referencing a 'naming.IObjectFactory', or you can define |
|
| a factory in the 'peak.naming.factories' property space. |
- SQL transaction semantics have changed. Now, issuing an SQL statement |
| |
*always* causes the connection to join the active PEAK transaction, even if |
| |
you request that the SQL be issued "outside" a transaction. Such SQL will |
| |
be issued outside of the *database* transaction, but not outside of the |
| |
PEAK transaction. This simplifies the overall processing model for dealing |
| |
with "untransacted" SQL such as Sybase DDL or read-only Oracle transactions. |
| |
(In particular, the requirement that triggered this change was to allow |
| |
Oracle read-only transactions to be released at the end of the current PEAK |
| |
transaction.) Also, got rid of the now-meaningless 'begin' command in n2. |
| |
|
| |
- The 'events.IEventSource' interface now returns a 'canceller' function from |
| |
the 'addCallback()' method, allowing you to cancel a previously-scheduled |
| |
callback. This fixes a memory leak and performance problem with |
| |
'events.AnyOf()', which previously could accumulate unneeded callbacks on |
| |
the sources it was monitoring. Note that if you have developed any custom |
| |
event sources with 'addCallback()' methods, you must make sure that they |
| |
return a canceller from now on. |

|
| |
- Added 'ref:factory@addr1||addr2' URL scheme that maps to a corresponding |
| |
'naming.Reference("factory",["addr1","addr2"])'. 'factory' can be either a |
| |
dotted import string referencing a 'naming.IObjectFactory', or you can |
| |
define a factory in the 'peak.naming.factories' property space. |
| |
|
| - Added a 'zconfig.schema' factory, so that 'ref:zconfig.schema@streamURL' |
- Added a 'zconfig.schema' factory, so that 'ref:zconfig.schema@streamURL' |
