Do you rely on user-installed add-ons?

If you are upgrading from Stash 3.x to Bitbucket Server 4.x, you should be aware that most user-installed add-ons will be incompatible with Bitbucket Server 4.0. After upgrading, go to Admin > Manage add-ons, look for messages of this form, and follow the advice to update:

If no newer version is available the add-on will remain disabled. 

New dedicated user account 'atlbitbucket'

A new dedicated user account will be created to run Bitbucket Server, called atlbitbucket. During the upgrade process, you will have an option to delete the dedicated user account for running Stash, named atlstash. For most users, deleting this dedicated user account won't have any negative consequences, however if you rely on this dedicated user accounts, for example in custom backup scripts, you will need to update the user account in those scripts.

Updates to logger names

If you have customized your logging configuration by manually editing the logback.xml file (using steps found in the Configure Stash Logging KB article), you should be aware of changes to several logger names that may require you to update some of your configuration files.

Important security improvement which may require configuration changes

Previous to Bitbucket Server 4.0, a security constraint for redirecting from HTTP to HTTPS was not enforced, meaning users could type "http://<bitbucketserver-url>" into their browser and still be shown a functioning version of Bitbucket Server (or Stash). Included with the release of Bitbucket Server 4.0 was a fix to enforce that security constraint. Using the previous security configuration with Bitbucket Server 4.0 means trying to access the application over an insecure connection, when users type "http" when trying to get to the application, they could encounter erroneous behavior. 

As part of upgrading from Stash to Bitbucket Server, it is recommended you update your security configuration in order to avoid encountering this problem. See this Knowledge Base article for more information and specific instructions on addressing this: Redirect HTTP Requests to HTTPS.

Have you made customizations to Tomcat's server.xml file?

For Stash 3.8 (and future versions) the server.xml file is now located in the <stash home directory>/shared directory. The benefit of this move is that your customizations to server.xml will not have to be redone for future upgrades.

 You still need to update your custom configurations in shared/server.xml for the upgrade to Stash 3.8.

Deprecation of HighlightJS for syntax highlighting

The highlighting engine was changed in Stash 3.5 from HighlightJS to CodeMirror. The use of HighlightJS for syntax highlighting in Stash is now deprecated, and will be removed in Stash 4.0. See Syntax highlight changes for information about how to migrate any custom mappings for HighlightJS that you may have made.

Secure email notifications

Stash 3.6 now:

• Allows you to require STARTTLS support on the mail server when using SMTP – if it is not supported, mail is not sent. 
• Supports SMTPS (where the whole protocol conversation uses SSL/TLS).

See Setting up your mail server for more information.

Note that if you use either SMTP with STARTTLS or SMTPS and connect to a self-signed mail server you may need to import the server's certificate and set up a custom cacerts file for Stash (just as you do for any outbound SSL/TLS connection to a self-signed server). See this  Stash knowledge base article for information about how to do that.

Deprecation of HighlightJS for syntax highlighting

Stash home directory location

Stash 3.5 and later versions no longer allow the Bitbucket Server home directory to be the same directory as, or a subdirectory of, the Stash installation directory. The Stash home directory, as defined by the STASH_HOME environment variable, must be in a separate location – Stash will fail on startup otherwise.

Changed group membership aggregation with multiple user directories

Stash 3.4 uses new schemes to determine the effective group memberships when Stash is connected to multiple user directories, and duplicate user names and group names are used across those directories. The new schemes are: 

• 'aggregating membership'
• 'non-aggregating membership'.

These group membership schemes are only used to determine authorization. Authentication is determined on the basis of the group mappings in each directory.

See Effective memberships with multiple directories in the Crowd documentation for more information.

When you update to Stash 3.4, an update task will apply one of those schemes as follows:

Aggregating membership will be applied to your instance:

• • If there is only one active directory.
  • If there are multiple active directories but only a single directory applies group memberships to any particular user.
  • For example, if directory-1 contains user-a in group-x, and directory-2 contains user-b in group-y, then Stash 3.4 will apply aggregating membership, and permissions will not be affected.

Non-aggregating membership will be applied to your instance:

• • If there are multiple active directories and more than one directory applies group memberships to at least one user.
  • For example, if directory-1 contains user-a in group-x, and directory-2 contains user-a in group-y, then Stash 3.4 will apply non-aggregating membership. If group-y has admin provileges then user-a would have their privileges escalated in this case if aggregating membership was applied instead when upgrading to Stash 3.4.

Any changes made by the update task will be logged.

A Stash admin can change the membership scheme used by Stash using the following commands:

• To change to aggregating membership, substitute your own values for <username>, <password> and <base-url> in this command:

  curl -H 'Content-type: application/json' -X PUT -d '{"membershipAggregationEnabled":true}' -u <username>:<password> <base-url>/rest/crowd/latest/application 

• To change to non-aggregating membership, substitute your own values for <username>, <password> and <base-url> in this command:

  curl -H 'Content-type: application/json' -X PUT -d '{"membershipAggregationEnabled":false}' -u <username>:<password> <base-url>/rest/crowd/latest/application

Note that changing the aggregation scheme can affect the authorization permissions for your Stash users, and how update operations are performed. Read more about using Stash with multiple use directories.

Home directory migration

When you update to Stash 3.2 or later, an update task migrates directories in your Stash home directory to new locations. This is irreversible – once you update to Stash 3.2 or later you can not revert to Stash 3.1 or earlier, because of changes to the Stash home directory format.

For most installations, Stash 3.2 is able to perform these moves automatically and transparently. However, in the rare instance where Stash 3.2 can't perform the update automatically, please refer to Upgrading your Stash home directory for Stash 3.2 manually.

Undocumented home directory overrides are no longer supported

Pull Request Ref Optimization

When you first start Stash after upgrading to Stash 2.9 a repository update task runs that optimizes the pull request refs for all repositories managed by Stash. It's important that you do not interrupt this update process. You can track the progress of this in the Stash logs. See  STASH-3469 - Getting issue details... STATUS .

Repository System Information Plugin is now deprecated

The functionality of the repository system information plugin has now been moved into core Stash. The plugin will still work for Stash 2.x versions but is redundant as of Stash 2.7.

MySQL default isolation level

Stash 2.7.x uses READ_COMMITTED instead of the MySQL default isolation level (REPEATABLE_READ). This can result in exceptions when installing or upgrading to 2.7.x, if binary logging is enabled in your MySQL server. More details and a fix can be found in this KB article.

Install location for third-party libraries

As of Stash 2.1 you can install third-party libraries and jar files, such as the MySQL JDBC driver, into <Stash home directory>/lib. This has the advantage that files in this location are not overwritten, and lost, when you update Stash.

Microsoft SQL Server JDBC driver

Stash 2.1 now uses the Microsoft SQL Server JDBC driver to access Microsoft SQL Server, instead of using the jTDS driver. In most cases, Stash will automatically swap to using the Microsoft driver on update and no configuration is required.

If Stash was configured to use Microsoft SQL Server by manually entering a JDBC URL, please refer to this guide.

Stash 2.0 update notes

This section provides specific notes for upgrading to Stash 2.0. See also the update steps section above.

Tomcat

For Stash 2.0, Tomcat has been updated from version 6 to 7. As part of that update, the server.xml file has changed. If you have customized server.xml (for example, for port, path or hostname), you can not simply copy your own version across to the updated Stash; you must reapply your customizations to the server.xml file for the new version of Stash.

If you were running Stash as a Windows service and are upgrading from 1.x to 2.x you will need to reinstall the Stash service to make it use Tomcat 7.

To uninstall the Stash service you need to execute following commands from <STASH DISTRIBUTION DIR>\bin:

> net stop <service name>
> service.bat uninstall <service name>

You can call this command without the service name if you installed the Stash service with a default name.

After the service is uninstalled you can proceed with the update steps and Running Bitbucket Server as a Windows service instructions to configure Stash 2.x running as a service.

Perl

Stash 2.0 requires Perl for its branch permission functionality. If Perl is unavailable, Stash 2.0 will not start.

On Windows machines, Perl will only have been installed by the Git installer if the correct install option was chosen. See Installing and upgrading Git.

Existing Git hooks

In order to support Branch Permissions, Stash 2.0 moves existing hooks in the pre-receive and post-receive folders under  <Stash home directory>/data/repositories/NNNN/hooks (where NNN is the internal repository id)  to .../hooks/pre-receive.d/10_custom or .../hooks/post-receive.d/10_custom. Consequently, custom hooks that use relative path names (e.g. "./foo.sh" or "../dir/foo.sh") will be broken by the update to Stash 2.0.

Deprecation of Internet Explorer 8

Support for Internet Explorer 8 is deprecated from the release of Stash 2.0. The official end-of-support date is yet to be determined. See Supported platforms for details.
