Upgrade notes for 11.0

These notes give additional information about changes. Please always follow the main upgrade guide.

For docker based version, please check upgrade Seafile Docker image

Important release changes

Change of user identity

Previous Seafile versions directly used a user's email address or SSO identity as their internal user ID.

Seafile 11.0 introduces virtual user IDs - random, internal identifiers like "adc023e7232240fcbb83b273e1d73d36@auth.local". For new users, a virtual ID will be generated instead of directly using their email. A mapping between the email and virtual ID will be stored in the "profile_profile" database table. For SSO users,the mapping between SSO ID and virtual ID is stored in the "social_auth_usersocialauth" table.

Overall this brings more flexibility to handle user accounts and identity changes. Existing users will use the same old ID.

Reimplementation of LDAP Integration

Previous Seafile versions handled LDAP authentication in the ccnet-server component. In Seafile 11.0, LDAP is reimplemented within the Seahub Python codebase.

LDAP configuration has been moved from ccnet.conf to seahub_settings.py. The ccnet_db.LDAPImported table is no longer used - LDAP users are now stored in ccnet_db.EmailUsers along with other users.

Benefits of this new implementation:

  • Improved compatibility across different systems. Python code is more portable than the previous C implementation.
  • Consistent handling of users whether they login via LDAP or other methods like email/password.

The upgrade script will merge ccnet_db.LDAPImported table to ccnet_db.EmailUsers table. The setting files need to be changed manually.

OAuth authentication and other SSO methods

If you use OAuth authentication, the configuration need to be changed a bit.

If you use SAML, you don't need to change configuration files.

Deprecating SQLite Database Support

Seafile 11.0 deprecates using SQLite as the database. There are several reasons driving this change:

  • Focus on collaborative features - SQLite's limitations make advanced concurrency and locking difficult, which collaborative editing requires. Different Seafile components need simultaneous database access.
  • Docker deployments - Our official Docker images do not support SQLite. MySQL is the preferred option.
  • Migration difficulties - Migrating SQLite databases to MySQL via SQL translation is unreliable.

To migrate from SQLite database to MySQL database, you can follow the document Migrate from SQLite to MySQL

ElasticSearch change (pro edition only)

Elasticsearch version is not changed in Seafile version 11.0

New SAML prerequisites (MULTI_TENANCY only)

For Ubuntu 20.04/22.04

sudo apt-get update
sudo apt-get install -y dnsutils

For CentOS 8

sudo yum install bind-utils -y

Django CSRF protection issue

Django 4.* has introduced a new check for the origin http header in CSRF verification. It now compares the values of the origin field in HTTP header and the host field in HTTP header. If they are different, an error is triggered.

If you deploy Seafile behind a proxy, or if you use a non-standard port, or if you deploy Seafile in cluster, it is likely the origin field in HTTP header received by Django and the host field in HTTP header received by Django are different. Because the host field in HTTP header is likely to be modified by proxy. This mismatch results in a CSRF error.

You can add CSRF_TRUSTED_ORIGINS to seahub_settings.py to solve the problem:

CSRF_TRUSTED_ORIGINS = ["https://<your-domain>"]

New Python libraries

Note, you should install Python libraries system wide using root user or sudo mode.

For Ubuntu 20.04/22.04

sudo apt-get update
sudo apt-get install -y python3-dev ldap-utils libldap2-dev

sudo pip3 install future==0.18.* mysqlclient==2.1.* pillow==10.2.* sqlalchemy==2.0.18 captcha==0.5.* django_simple_captcha==0.6.* djangosaml2==1.5.* pysaml2==7.2.* pycryptodome==3.16.* cffi==1.15.1 python-ldap==3.4.3

Upgrade to 11.0.x

1) Stop Seafile-10.0.x server.

2) Start from Seafile 11.0.x, run the script:

upgrade/upgrade_10.0_11.0.sh

3)Modify configurations and migrate LDAP records

Change configurations for LDAP

The configuration items of LDAP login and LDAP sync tasks are migrated from ccnet.conf to seahub_settings.py. The name of the configuration item is based on the 10.0 version, and the characters 'LDAP_' or 'MULTI_LDAP_1' are added. Examples are as follows:

# Basic configuration items for LDAP login
ENABLE_LDAP = True
LDAP_SERVER_URL = 'ldap://192.168.0.125'     # The URL of LDAP server
LDAP_BASE_DN = 'ou=test,dc=seafile,dc=ren'   # The root node of users who can 
                                             # log in to Seafile in the LDAP server
LDAP_ADMIN_DN = 'administrator@seafile.ren'  # DN of the administrator used 
                                             # to query the LDAP server for information

                                             # the table social_auth_usersocialauth, defaults to 'ldap'
LDAP_LOGIN_ATTR = 'userPrincipalName'        # User's attribute used to log in to Seafile, 
                                             # can be mail or userPrincipalName, cannot be changed
LDAP_FILTER = 'memberOf=CN=testgroup,OU=test,DC=seafile,DC=ren'  # Additional filter conditions,
                                                                 # users who meet the filter conditions can log in, otherwise they cannot log in
# For update user info when login
LDAP_CONTACT_EMAIL_ATTR = ''             # For update user's contact_email

Migrate LDAP records

Run the following script to migrate users in LDAPImported to EmailUsers

python3 migrate_ldapusers.py

Change configuration for OAuth:

In the new version, the OAuth login configuration should keep the email attribute unchanged to be compatible with new and old user logins. In version 11.0, a new uid attribute is added to be used as a user's external unique ID. The uid will be stored in social_auth_usersocialauth to map to internal virtual ID. For old users, the original email is used the internal virtual ID. The example is as follows:

# Version 10.0 or earlier
OAUTH_ATTRIBUTE_MAP = {
    "id": (True, "email"),
    "name": (False, "name"),
    "email": (False, "contact_email"),
}

# Since 11.0 version, added 'uid' attribute.
OAUTH_ATTRIBUTE_MAP = {
    "id": (True, "email"),  # In the new version, the email attribute configuration should be kept unchanged to be compatible with old and new user logins
    "uid": (True, "uid"),   # Seafile use 'uid' as the external unique identifier of the user. Different OAuth systems have different attributes, which may be: 'uid' or 'username', etc.
    "name": (False, "name"),
    "email": (False, "contact_email"),
}

4) Start Seafile-11.0.x server.
