====================================== Upgrading to newer versions of Roundup ====================================== Please read each section carefully and edit your instance home files accordingly. .. contents:: Migrating from 0.4.x to 0.5.0 ============================= This has been a fairly major revision of Roundup: 1. Brand new, much more powerful, flexible, tasty and nutritious templating. Unfortunately, this means all your current templates are useless. Please don't hesitate to ask on roundup-users for help (or complete conversions if you're completely stuck)! 2. The database backed got a lot more flexible, allowing Metakit and SQL databases! The only SQL database implemented at present is gadfly, but others shouldn't be a whole lot more work. 3. A brand new, highly flexible and much more robust security system including a system of Permissions, Roles and Role assignments to users. You may now define your own Permissions that may be checked in CGI transactions. 4. Journalling has been made less storage-hungry, so has been turned on by default *except* for author, recipient and nosy link/unlink events. You are advised to turn it off in your instances too. 5. Because of the above changes, the instance configuration has seen some major changes. See below for the details. Please, *back up your database* before you start the migration process. This is as simple as copying the "db" directory and all its contents from your instance to somewhere safe. 0.5.0 Configuration ------------------- Due to the new templating having a top-level ``page`` that defines links for searching, indexes, adding items etc, the following variables are no longer used: - HEADER_INDEX_LINKS - HEADER_ADD_LINKS - HEADER_SEARCH_LINKS - SEARCH_FILTERS - DEFAULT_INDEX - UNASSIGNED_INDEX - USER_INDEX - ISSUE_FILTER The new security implementation will require additions to the dbinit module, but also removes the need for the following instance config variables: - ANONYMOUS_ACCESS - ANONYMOUS_REGISTER but requires two new variables which define the Roles assigned to users who register through the web and e-mail interfaces: - NEW_WEB_USER_ROLES - NEW_EMAIL_USER_ROLES in both cases, 'User' is a good initial setting. To emulate ``ANONYMOUS_ACCESS='deny'``, remove all "View" Permissions from the "Anonymous" Role. To emulate ``ANONYMOUS_REGISTER='deny'``, remove the "Web Registration" and/or the "Email Registration" Permission from the "Anonymous" Role. See the section on customising security in the `customisation documentation`_ for more information. 0.5.0 Schema Specification -------------------------- 0.5.0 Database backend changes ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Your select_db module in your instance has changed a fair bit. Where it used to contain:: # WARNING: DO NOT EDIT THIS FILE!!! from roundup.backends.back_anydbm import Database it must now contain:: # WARNING: DO NOT EDIT THIS FILE!!! from roundup.backends.back_anydbm import Database, Class, FileClass, IssueClass Note the addition of the Class, FileClass, IssueClass imports. These are very important, as they're going to make the next change work too. You now need to modify the top of the dbinit module in your instance from:: import instance_config from roundup import roundupdb from select_db import Database from roundup.roundupdb import Class, FileClass class Database(roundupdb.Database, select_db.Database): ''' Creates a hybrid database from: . the selected database back-end from select_db . the roundup extensions from roundupdb ''' pass class IssueClass(roundupdb.IssueClass): ''' issues need the email information ''' pass to just:: import instance_config from select_db import Database, Class, FileClass, IssueClass Yes, remove the Database and IssueClass definitions and those other imports. They're not needed any more! 0.5.0 Journalling changes ~~~~~~~~~~~~~~~~~~~~~~~~~ Journalling has been optimised for storage. Journalling of links has been turned back on by default. If your tracker has a large user base, you may wish to turn off journalling of nosy list, message author and message recipient link and unlink events. You do this by adding ``do_journal='no'`` to the Class initialisation in your dbinit. For example, your *msg* class initialisation probably looks like this:: msg = FileClass(db, "msg", author=Link("user"), recipients=Multilink("user"), date=Date(), summary=String(), files=Multilink("file"), messageid=String(), inreplyto=String()) to turn off journalling of author and recipient link events, add ``do_journal='no'`` to the ``author=Link("user")`` part of the statement, like so:: msg = FileClass(db, "msg", author=Link("user", do_journal='no'), recipients=Multilink("user", do_journal='no'), date=Date(), summary=String(), files=Multilink("file"), messageid=String(), inreplyto=String()) Nosy list link event journalling is actually turned off by default now. If you want to turn it onn, change to your issue class' nosy list, change its definition from:: issue = IssueClass(db, "issue", assignedto=Link("user"), topic=Multilink("keyword"), priority=Link("priority"), status=Link("status")) to:: issue = IssueClass(db, "issue", nosy=Multilink("user", do_journal='yes'), assignedto=Link("user"), topic=Multilink("keyword"), priority=Link("priority"), status=Link("status")) noting that your definition of the nosy Multilink will override the normal one. 0.5.0 User schema changes ~~~~~~~~~~~~~~~~~~~~~~~~~ Users have two more properties, "queries" and "roles". You'll have something like this in your dbinit module now:: user = Class(db, "user", username=String(), password=Password(), address=String(), realname=String(), phone=String(), organisation=String(), alternate_addresses=String()) user.setkey("username") and you'll need to add the new properties and the new "query" class to it like so:: query = Class(db, "query", klass=String(), name=String(), url=String()) query.setkey("name") # Note: roles is a comma-separated string of Role names user = Class(db, "user", username=String(), password=Password(), address=String(), realname=String(), phone=String(), organisation=String(), alternate_addresses=String(), queries=Multilink('query'), roles=String()) user.setkey("username") The "queries" property is used to store off the user's favourite database queries. The "roles" property is explained below in `0.5.0 Security Settings`_. 0.5.0 Security Settings ~~~~~~~~~~~~~~~~~~~~~~~ See the `security documentation`_ for an explanation of how the new security system works. In a nutshell though, the security is handled as a four step process: 1. Permissions are defined as having a name and optionally a hyperdb class they're specific to, 2. Roles are defined that have one or more Permissions, 3. Users are assigned Roles in their "roles" property, and finally 4. Roundup checks that users have appropriate Permissions at appropriate times (like editing issues). Your instance dbinit module's *open* function now has to define any Permissions that are specific to your instance, and also the assignment of Permissions to Roles. At the moment, your open function ends with:: import detectors detectors.init(db) return db and what we need to do is insert some commands that will set up the security parameters. Right above the ``import detectors`` line, you'll want to insert these lines:: # # SECURITY SETTINGS # # new permissions for this schema for cl in 'issue', 'file', 'msg', 'user': db.security.addPermission(name="Edit", klass=cl, description="User is allowed to edit "+cl) db.security.addPermission(name="View", klass=cl, description="User is allowed to access "+cl) # Assign the access and edit permissions for issue, file and message # to regular users now for cl in 'issue', 'file', 'msg': p = db.security.getPermission('View', cl) db.security.addPermissionToRole('User', p) p = db.security.getPermission('Edit', cl) db.security.addPermissionToRole('User', p) # and give the regular users access to the web and email interface p = db.security.getPermission('Web Access') db.security.addPermissionToRole('User', p) p = db.security.getPermission('Email Access') db.security.addPermissionToRole('User', p) # May users view other user information? Comment these lines out # if you don't want them to p = db.security.getPermission('View', 'user') db.security.addPermissionToRole('User', p) # Assign the appropriate permissions to the anonymous user's Anonymous # Role. Choices here are: # - Allow anonymous users to register through the web p = db.security.getPermission('Web Registration') db.security.addPermissionToRole('Anonymous', p) # - Allow anonymous (new) users to register through the email gateway p = db.security.getPermission('Email Registration') db.security.addPermissionToRole('Anonymous', p) # - Allow anonymous users access to the "issue" class of data # Note: this also grants access to related information like files, # messages, statuses etc that are linked to issues #p = db.security.getPermission('View', 'issue') #db.security.addPermissionToRole('Anonymous', p) # - Allow anonymous users access to edit the "issue" class of data # Note: this also grants access to create related information like # files and messages etc that are linked to issues #p = db.security.getPermission('Edit', 'issue') #db.security.addPermissionToRole('Anonymous', p) # oh, g'wan, let anonymous access the web interface too p = db.security.getPermission('Web Access') db.security.addPermissionToRole('Anonymous', p) Note in the comments there the places where you might change the permissions to restrict users or grant users more access. If you've created additional classes that users should be able to edit and view, then you should add them to the "new permissions for this schema" section at the start of the security block. Then add them to the "Assign the access and edit permissions" section too, so people actually have the new Permission you've created. One final change is needed that finishes off the security system's initialisation. We need to add a call to ``db.post_init()`` at the end of the dbinit open() function. Add it like this:: import detectors detectors.init(db) # schema is set up - run any post-initialisation db.post_init() return db You may verify the setup of Permissions and Roles using the new "``roundup-admin security``" command. 0.5.0 User changes ~~~~~~~~~~~~~~~~~~ To support all those schema changes, you'll need to massage your user database a little too, to: 1. make sure there's an "anonymous" user - this user is mandatory now and is the one that unknown users are logged in as. 2. make sure all users have at least one Role. If you don't have the "anonymous" user, create it now with the command:: roundup-admin create user username=anonymous roles=Anonymous making sure the capitalisation is the same as above. Once you've done that, you'll need to set the roles property on all users to a reasonable default. The admin user should get "Admin", the anonymous user "Anonymous" and all other users "User". The ``fixroles.py`` script in the tools directory will do this. Run it like so (where python is your python 2+ binary):: python tools/fixroles.py -i 0.5.0 CGI interface changes --------------------------- The CGI interface code was completely reorganised and largely rewritten. The end result is that this section of your instance interfaces module will need changing from:: from roundup import mailgw from roundup.cgi import client class Client(client.Client): ''' derives basic CGI implementation from the standard module, with any specific extensions ''' pass to:: from roundup import cgi_client, mailgw from roundup.i18n import _ class Client(cgi_client.Client): ''' derives basic CGI implementation from the standard module, with any specific extensions ''' pass 0.5.0 HTML templating --------------------- You'll want to make a backup of your current instance html directory. You should then copy the html directory from the Roundup source template that you used to create your instance, and modify it according to your local schema changes. If you need help with the new templating system, please ask questions on the roundup-users mailing list (available through the roundup project page on sourceforge, http://roundup.sf.net/) 0.5.0 Detectors --------------- The nosy reactor has been updated to handle the instance not having an "assignedto" property on issues. You may want to copy it into your instance's detectors directory. Chances are you've already fixed it though :) Migrating from 0.4.1 to 0.4.2 ============================= 0.4.2 Configuration ------------------- The USER_INDEX definition introduced in 0.4.1 was too restrictive in its allowing replacement of 'assignedto' with the user's userid. Users must change the None value of 'assignedto' to 'CURRENT USER' (the string, in quotes) for the replacement behaviour to occur now. The new configuration variables are: - EMAIL_KEEP_QUOTED_TEXT - EMAIL_LEAVE_BODY_UNCHANGED - ADD_RECIPIENTS_TO_NOSY See the sample configuration files in:: /roundup/templates/classic/instance_config.py and:: /roundup/templates/extended/instance_config.py and the `customisation documentation`_ for information on how they're used. 0.4.2 Changes to detectors -------------------------- You will need to copy the detectors from the distribution into your instance home "detectors" directory. If you used the classic schema, the detectors are in:: /roundup/templates/classic/detectors/ If you used the extended schema, the detectors are in:: /roundup/templates/extended/detectors/ The change means that schema-specific code has been removed from the mail gateway and cgi interface and made into auditors: - nosyreactor.py has now got an updatenosy auditor which updates the nosy list with author, recipient and assignedto information. - statusauditor.py makes the unread or resolved -> chatting changes and presets the status of an issue to unread. There's also a bug or two fixed in the nosyreactor code. 0.4.2 HTML templating changes ----------------------------- The link() htmltemplate function now has a "showid" option for links and multilinks. When true, it only displays the linked node id as the anchor text. The link value is displayed as a tooltip using the title anchor attribute. To use in eg. the superseder field, have something like this::
View: The stylesheets have been cleaned up too. You may want to use the newer versions in:: /roundup/templates/
