Other Modifications made to the 1.0 API
Take the will be removed in version 1.1.1 comments in the code seriously. The earlier the planned API changes in 1.1.x, the better (gives more time to plugin authors to adapt). TODO
Wiki page version comments can now be edited, so
wiki_page_comment_modified(page, old_comment) has been added to allow plugins to be notified of this.
Notification API Changes
Database API Changes
Methods have been added to
DatabaseManager class for settings and retrieving the database version for Trac and plugins:
Environment.get_db_cnx has been removed
Following the deprecation made in 0.12, the method
Environment.get_db_cnx has been removed.
One should now only use the context managers for retrieving a database Connection in read or write mode.
- a read-only Connection can be used to form queries:
with env.db_query as db: ...
dbinstance obtained the above way should only be used for executing SELECT queries
- a writable Connection can be used to modify the database content in a transaction:
with env.db_transaction as db: ...
dbinstance obtained the above way can be used to execute INSERT/UPDATE/DELETE queries; they will be committed when the last such automatic transaction in the control flow completes successfully. See DatabaseApi for the full details.
Environment.get_read_db and the decorators
env.with_transaction() have been deprecated since Trac 1.0 and will be removed in Trac 1.3.1.
db parameters removed from function and method signatures
With the introduction of
@with_transaction(env) decorators in 0.12 and continuing with the introduction of the database connection context managers in 1.0, the
db parameters passed as function and method arguments became deprecated.
db parameters have been removed from nearly all function and method signatures. The
db arguments are still present on methods of
IEnvironmentParticipant implementations, but are deprecated and should no longer be used. They will be removed in 1.3.1.
ConnectionBase class defines an abstract interface that database backends must adhere to when implementing a
Template and CSS changes
tt tags are not support in HTML5 and have been replaced with
code tags in Trac (#11094). The styling of
code tags is the same in Trac , but
code tags should be used since the styling for
tt tags will be removed in a future version of Trac.
about.css stylesheet has been removed and the rules contained in that stylesheet have been moved to
trac.css. The table of environment information on the Error and About pages have been extracted to a new template
environment_info.html and the markup and associated rules in the stylesheet have been significantly changed.
DONE Removed the deprecated
authname parameter from
TODO Log warnings for deprecated functions and methods (comment:26:ticket:11605)
