Review request for dbconfig-common with new packages



Hi all,

Although I bothered you not so long ago, I ask your review again (I
included the changes of bug 805455).

Please find attached the templates and control file of the
dbconfig-common source package and the diffs with respect to the
previously reviewed files. In my next upload I am going to add multiple
new packages, each with the same purpose with respect to the
dbconfig-common main package, i.e. to make sure that the support for the
proper database type is available.

I don't believe there is currently a need to review all the text in the
templates, but please review the altered sections and the descriptions
in the control file.

Your help is much appreciated.

Paul
As always, please CC me on replies.

Description: framework that helps packages to manage databases
 This package contains the core of the dbconfig-common framework. This
 framework presents a policy and implementation for managing various databases
 used by applications included in Debian packages.
 .
 It can:
  - support MySQL, PostgreSQL, and SQLite based applications;
  - create or remove databases and database users;
  - access local or remote databases;
  - upgrade/modify databases when upstream changes database structure;
  - generate config files in many formats with the database info;
  - import configs from packages previously managing databases on their own;
  - prompt users with a set of normalized, pre-translated questions;
  - handle failures gracefully, with an option to retry;
  - do all the hard work automatically;
  - work for package maintainers with little effort on their part;
  - work for local admins with little effort on their part;
  - comply with an agreed upon set of standards for behavior;
  - do absolutely nothing if that is the whim of the local admin;
  - perform all operations from within the standard flow of
    package management (no additional skill is required of the local
    admin).

 handle setup and maintenance. This package is intended for systems where the
 system administrator requires or desires full control of the database or where
 dbconfig-common makes the wrong choises. Typically this will leave the
 depending packages non-functional until the required actions are performed.

Template: dbconfig-common/remote-questions-default
Type: boolean
Default: false
_Description: Will this server be used to access remote databases?
 For the database types that support it, dbconfig-common includes support
 for configuring databases on remote systems. When installing a package's
 database via dbconfig-common, the questions related to remote
 configuration are asked with a priority such that they are
 skipped for most systems.
 .
 If you select this option, the default behavior will be to prompt you
 with questions related to remote database configuration when you install
 new packages.
 .
 If you are unsure, you should not select this option.

Template: dbconfig-common/remember-admin-pass
Type: boolean
Default: false
_Description: Keep "administrative" database passwords?
 By default, you will be prompted for all administrator-level database
 passwords when you configure, upgrade, or remove applications with
 dbconfig-common. These passwords will be stored in debconf's configuration
 database only for as long as they are needed.
 .
 This behavior can be disabled, in which case the passwords will
 remain in the debconf database. This database is protected by Unix file
 permissions, though this is less secure and thus not the default setting.
 .
 If you would rather not be bothered for an administrative password
 every time you upgrade a database application with dbconfig-common,
 you should choose this option. Otherwise, you should refuse this option.

Template: dbconfig-common/dbconfig-install
Type: boolean
Default: true
_Description: Configure database for ${pkg} with dbconfig-common?
 The ${pkg} package must have a database installed and configured before
 it can be used. This can be optionally handled with dbconfig-common.
 .
 If you are an advanced database administrator and know that you want
 to perform this configuration manually, or if your database has already
 been installed and configured, you should refuse this option. Details on what
 needs to be done should most likely be provided in /usr/share/doc/${pkg}.
 .
 Otherwise, you should probably choose this option.

Template: dbconfig-common/dbconfig-reinstall
Type: boolean
Default: false
_Description: Reinstall database for ${pkg}?
 Since you are reconfiguring ${pkg}, you may also want to reinstall the
 database which it uses.
 .
 If you wish to reinstall the database for ${pkg}, you should select
 this option. If you do not wish to do so (if you are reconfiguring
 the package for unrelated reasons), you should not select this option.
 .
 Warning: if you opt to reinstall the database and install it under a
 name that already exists, the old database will be dropped without
 further questions. In that case a backup of the original database is
 made in /var/tmp/.
 .
 Warning: if you change the name of the database, the old database will
 not be removed. If you change the name of the user that connects to
 the database, the privileges of the original user will not be revoked.

Template: dbconfig-common/dbconfig-upgrade
Type: boolean
Default: true
_Description: Perform upgrade on database for ${pkg} with dbconfig-common?
 According to the maintainer for this package, database upgrade
 operations need to be performed on ${pkg}. Typically, this is due to
 changes in how a new upstream version of the package needs to store
 its data.
 .
 If you want to handle this process manually, you should
 refuse this option. Otherwise, you should choose this option.
 During the upgrade, a backup of the database will be made in
 /var/cache/dbconfig-common/backups, from which the database can
 be restored in the case of problems.

Template: dbconfig-common/dbconfig-remove
Type: boolean
Default: true
_Description: Deconfigure database for ${pkg} with dbconfig-common?
 Since you are removing ${pkg}, it's possible that you no longer
 want the underlying database and the privileges for the user
 associated with this package.
 .
 Please choose whether database removal and privilege revocation should be
 handled with dbconfig-common.
 .
 If you choose this option, dbconfig-common will check if ${pkg} provided
 scripts and database commands to undo package specific operations and run them
 if they exist. Then it will ask if you want to delete the ${pkg} database and
 revoke the standard privileges for the user of ${pkg}. If you don't want any
 of this, or if you want to handle this manually, you should refuse this
 option.

Template: dbconfig-common/database-type
Type: select
Choices: ${database_types}
_Description: Database type to be used by ${pkg}:
 The ${pkg} package can be configured to use one of several database types.
 Below, you will be presented with the available choices.
 .
 It is possible that the package supports more database types than shown. In
 that case the corresponding dbconfig-<database type> packages are not installed
 so the options are removed for now. If you know that you want the package to use
 another supported database type, your best option is to backup the
 dbconfig-common questions and opt-out of dbconfig-common assistance for this
 package for now. After installation of the required dbconfig-<database type>,
 which can be found in the Depends list of this package, you can
 "dpkg-reconfigure ${pkg}" to choose your preferred database type.

Template: dbconfig-common/purge
Type: boolean
Default: false
_Description: Delete the database for ${pkg}?
 If you no longer need the database for ${pkg} and the privileges of
 the database user of ${pkg}, you can choose to delete the database and
 revoke the privileges now.
 .
 If you no longer have need of the data being stored by ${pkg}, you
 should choose this option. If you want to keep this data,
 or if you would rather handle this process manually, you should
 refuse this option. Either way, it won't affect your other databases.

Template: dbconfig-common/upgrade-backup
Type: boolean
Default: true
_Description: Back up the database for ${pkg} before upgrading?
 The underlying database for ${pkg} needs to be upgraded as part of the
 installation process. Just in case, the database can be backed up
 before this is done, so that if something goes wrong, you can revert
 to the previous package version and repopulate the database.

Template: dbconfig-common/password-confirm
Type: password
_Description: Password confirmation:

Template: dbconfig-common/app-password-confirm
Type: password
_Description: Password confirmation:

Template: dbconfig-common/passwords-do-not-match
Type: error
_Description: Password mismatch
 The password and its confirmation do not match.

Template: dbconfig-common/upgrade-error
Type: select
__Choices: abort, retry, retry (skip questions), ignore
Default: abort
#flag:translate!:3
#flag:comment:4
# Translators, note that the bullets have a leading space which means
# that debconf will not word-wrap those lines. This means that you
# will have to make sure that all lines in the list end with \n and
# you will have to keep the lines below 72 characters to avoid problems.
_Description: Next step for database upgrade:
 An error occurred while upgrading the database:
 .
 ${error}
 .
 Fortunately, ${dbfile} should hold a backup of the database, made just before
 the upgrade (unless the error occurred during backup creation, in which case
 no changes will have been applied yet). Your options are:
  * abort - Causes the operation to fail; you will need to downgrade,
    reinstall, reconfigure this package, or otherwise manually intervene
    to continue using it. This will usually also impact your ability to
    install other packages until the installation failure is resolved.
  * retry - Prompts once more with all the configuration questions
    (including ones you may have missed due to the debconf priority
    setting) and makes another attempt at performing the operation.
  * retry (skip questions) - Immediately attempts the operation again,
    skipping all questions. This is normally useful only if you have
    solved the underlying problem since the time the error occurred.
  * ignore - Continues the operation ignoring dbconfig-common errors.
    This will usually leave this package without a functional database.

_Description: Next step for database removal:
 An error occurred while removing the database:
 .
 ${error}
 .
 As a result it was not possible to remove the database for ${pkg}. Your
 options are:
  * abort - Causes the operation to fail; you will need to downgrade,
    reinstall, reconfigure this package, or otherwise manually intervene
    to continue using it. This will usually also impact your ability to
    install other packages until the installation failure is resolved.

    skipping all questions. This is normally useful only if you have
    solved the underlying problem since the time the error occurred.
  * ignore - Continues the operation ignoring dbconfig-common errors.
    This will usually leave the database and user privileges in place.

_Description: Next step:
 Configuring the database for ${pkg} requires the package ${dbpackage}
 to be installed and configured first, which is not something that can be
 checked for automatically.
 .
 Your options are:
  * abort - Choose this when in doubt and install ${dbpackage} before
    continuing with the configuration of this package. This causes the
    installation of ${pkg} to fail for now.
  * retry - Prompts once more with all the configuration questions
    (including ones you may have missed due to the debconf priority
    setting) and makes another attempt at performing the operation.
    Choose this if you chose the wrong database type by mistake.
  * ignore - Continues the operation ignoring dbconfig-common errors.
    This will usually leave this package without a functional database.

Template: dbconfig-common/remote/host
Type: select
Choices: ${hosts}
_Description: Host name of the ${dbvendor} database server for ${pkg}:
 Please select the remote hostname to use, or select "new host" to
 enter a new host.

Template: dbconfig-common/remote/port
Type: string
_Description: Port number for the ${dbvendor} service:
 Please specify the port the ${dbvendor} database on the remote host is
 running on. To use the default port, leave this field blank.

Template: dbconfig-common/remote/newhost
Type: string
_Description: Host running the ${dbvendor} server for ${pkg}:
 Please provide the hostname of a remote ${dbvendor} server.
 .
 You must have already arranged for the administrative
 account to be able to remotely create databases and grant
 privileges.

Template: dbconfig-common/db/dbname
Type: string
_Description: ${dbvendor} database name for ${pkg}:
 Please provide a name for the ${dbvendor} database to be used by ${pkg}.

Template: dbconfig-common/db/app-user
Type: string
_Description: ${dbvendor} username for ${pkg}:
 Please provide a ${dbvendor} username for ${pkg} to register with the
 database server. A ${dbvendor} user is not necessarily the same as a
 system login, especially if the database is on a remote server.
 .
 This is the user which will own the database, tables, and other
 objects to be created by this installation. This user will have
 complete freedom to insert, change, or delete data in the database.
 .
 If your username contains an @, you need to specify the domain as well
 (see below).
 .
 Advanced usage: if you need to define the domain that the user will log
 in from, you can write "username@domain".

Template: dbconfig-common/db/basepath
Type: string
_Description: ${dbvendor} storage directory for ${pkg}:
 Please provide a path where the ${dbvendor} database file for ${pkg}
 should be installed into.
 .
 The permissions for this directory will be set to match the permissions
 for the generated database file.

Template: dbconfig-common/mysql/method
Type: select
__Choices: Unix socket, TCP/IP
Default: Unix socket
_Description: Connection method for MySQL database of ${pkg}:
 By default, ${pkg} will be configured to use a MySQL server
 through a local Unix socket (this provides the best performance).
 To connect with a different method, or to a different server entirely,
 select the appropriate option from the choices here.

Template: dbconfig-common/mysql/app-pass
Type: password
_Description: MySQL application password for ${pkg}:
 Please provide a password for ${pkg} to register with the
 database server. If left blank, a random password will be
 generated.

Template: dbconfig-common/mysql/admin-user
Type: string
Default: root
_Description: Name of the database's administrative user:
 Please provide the name of the account with which this package should perform
 administrative actions. This user is the one with the power to create new
 database users.
 .
 For MySQL, this is almost always "root". Note that this is not the
 same as the Unix login "root".

Template: dbconfig-common/mysql/admin-pass
Type: password
_Description: Password of the database's administrative user:
 Please provide the password for the administrative account "${dbadmin}" with
 which this package should create its MySQL database and user.

Template: dbconfig-common/pgsql/method
Type: select
__Choices: Unix socket, TCP/IP, TCP/IP + SSL
Default: TCP/IP
_Description: Connection method for PostgreSQL database of ${pkg}:
 By default, ${pkg} will be configured to use a PostgreSQL server through
 TCP/IP because that method works in most circumstances. To connect with a
 different method, select the appropriate option from the choices here.

Template: dbconfig-common/pgsql/app-pass
Type: password
_Description: PostgreSQL application password for ${pkg}:
 Please provide a password for ${pkg} to register with the database
 server. If left blank, a random password will be generated.
 .
 If you are using "ident" authentication, the supplied password will not
 be used and can be left blank. Otherwise, PostgreSQL access may need to
 be reconfigured to allow password-authenticated access.

Template: dbconfig-common/pgsql/admin-user
Type: string
Default: postgres
_Description: Name of the database's administrative user:
 Please provide the name of the account with which this package should perform
 administrative actions. This user is the one with the power to create new
 database users.

Template: dbconfig-common/pgsql/admin-pass
Type: password
_Description: Password of your database's administrative user:
 Please provide the password for the ${dbadmin} account with which this package
 should perform administrative actions.
 .
 For a standard PostgreSQL installation, a database password is not
 required, since authentication is done at the system level.

Template: dbconfig-common/pgsql/authmethod-admin
Type: select
__Choices: ident, password
Default: ident
_Description: Method for authenticating the PostgreSQL administrator:
 PostgreSQL servers provide several different mechanisms for authenticating
 connections. Please select what method the administrative user should use
 when connecting to the server.
 .
 With "ident" authentication on the local machine, the server will
 check that the owner of the Unix socket is allowed to connect.
 PostgreSQL itself calls this peer authentication.
 .
 With "ident" authentication to remote hosts, RFC-1413-based ident is
 used (which can be considered a security risk).
 .
 With "password" authentication, a password will be passed to the server
 for use with some authentication backend (such as "MD5" or "PAM"). Note
 that the password is still passed in the clear across network
 connections if your connection is not configured to use SSL.
 .
 For a standard PostgreSQL installation running on the same host,
 "ident" is recommended.

 For a standard PostgreSQL installation running on the same host,
 "password" is recommended, because typically the system username
 doesn't match the database username.

Template: dbconfig-common/pgsql/no-user-choose-other-method
Type: note
# This template is currently unused
_Description: PostgreSQL connection method error
 Unfortunately, it seems that the database connection method you
 have selected for ${pkg} will not work, because it requires the existence
 of a local user that does not exist.

Template: dbconfig-common/pgsql/changeconf
Type: boolean
Default: false
#flag:translate!:3
# This template is currently unused
_Description: Change PostgreSQL configuration automatically?
 It has been determined that the database installation for ${pkg}
 cannot be automatically accomplished without making changes to
 the PostgreSQL server's access controls. It is suggested that this
 be done by dbconfig-common when the package is installed. If
 instead you would prefer to do it manually, the following line needs
 to be added to your pg_hba.conf:
 .
 ${pghbaline}

Template: dbconfig-common/pgsql/revertconf
Type: boolean
Default: false
#flag:translate!:3
# This template is currently unused
_Description: Revert PostgreSQL configuration automatically?
 As ${pkg} is now being removed, it may no longer be necessary to
 have an access control entry in the PostgreSQL server's configuration.
 While keeping such an entry will not break any software on the
 system, it may be seen as a potential security concern. It is suggested
