Subject [jira] Commented: (DERBY-3070) Developer's Guide upgrade topic "Soft upgrade limitations" needs updating for 10.3
Date Thu, 16 Apr 2009 14:46:15 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3070?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699722#action_12699722
] 

Kim Haase commented on DERBY-3070:
----------------------------------

The information in the soft upgrade topic (http://db.apache.org/derby/docs/dev/devguide/tdevupgradesoft.html)
is way out of date now. Updating it for each release is impractical, and no user has complained
about it. 

It would make more sense to remove release-specific information from the topic and to say
in general terms which kinds of new features can be used with soft upgrade and which kinds
can't. Specifically, features that "affect database structure" can't be used with soft upgrade.

I thought the release notes contained more specific information, but they don't seem to. Users
will have to figure out which features can be used with soft upgrade and which can't. Since
that is the situation currently for all releases after 10.2, this doesn't cause a significant
regression.

I'll post a patch soon unless someone has a better proposal.

> The "Soft upgrade limitations" topic in the Developer's Guide (http://db.apache.org/derby/docs/dev/devguide/tdevupgradesoft.html)
does not seem to have been updated for 10.3. Would it be possible for someone to provide lists
of the following, so I can make the edits:
> Version 10.3 features that can't be used in a database upgraded from 10.0 (are these
the same as the 10.2 features listed?)
> Version 10.3 features that can't be used in a database upgraded from 10.1 ((are these
the same as the 10.2 features listed?)
> Version 10.3 features that can't be used in a database upgraded from 10.2 (collation,
apparently; any others?)
> It would be good to know if the territory attribute needs to be added to one of these
lists (see DERBY-2185).
