In PG, TAP test framework is used to drive tests for backup and restore, replication, etc - anything that can't really be expressed using pg_regress or the isolation test framework. Basically, it can be used if we want something more than just comparing the expected outputs. It may include: 1. Some engine/os configuration changes 2. Start or stop the server 3. grep log messages from log file and match with expected log file output 4. system calls In Babelfish, we can utilize the same test framework for the following scenarios: 1. pg_hba.conf changes with password authentication 2. Kerberos authentication by setting up MIT kerberos 3. SSL setup and test encrypted connection 4. Different Provisioning scenarios Authored-by: Kuntal Ghosh <[email protected]>

This commit adds the support for T-SQL linked server objects through PostgreSQL foreign data wrappers (FDWs). Currently, only support for linked servers for remote SQL Servers is added. Thus, to add linked servers of this type, the tds_fdw extension needs to be installed. Also, added the support for T-SQL sp_addlinkedserver stored procedure to add a linked server in Babelfish and sys.servers system view to show list of linked servers. sp_addlinkedserver stored procedure has been implemented such that internally it uses PG's CREATE FOREIGN SERVER logic and so, a linked server added is internally a PG foreign server. sys.servers system view uses the pg_foreign_server catalog internally.

…ish-for-postgresql#1018) In T-SQL world, Authentication mechanism would be chosen by the client as opposed to Postgres where authentication method selection would be controlled through pg_hba.conf file on server side. For example, TDS client such as sqlcmd would not specify any username in login packet when it wants to use Kerberos/NTLM authentication. So in order to support Kerberos authentication, this commit avoids consulting pg_hba.conf file if sspi data is present in login request during authentication.

…ql#990) (babelfish-for-postgresql#1028) Previously every call to the function VarCharToDatum() previously used TDSGetEncoding() function which internally called LookupEncodingByLCID().For bulk insert scenario for every row in a table for a varchar, char, text column we called VarCharToDatum function which lead to extra calls to LookupEncodingByLCID function causing an overhead. The current solution implemented is to at the start of request set the encoding of the column as a part of columnMetadata for both bulk insert as well as Tvp(Table valued Parameters). This would remove the redundant calls to LookupEncodingByLCID. Issues Resolved: BABEL-3623 Signed-off-by: Nirmit Shah [email protected]

…admin Previously, when adding a member to sysadmin role, there was no check on whether current login has DB user in one of the databases. As Babelfish does not support >1 dbo, every login has to be checked if it is a user already when being added to sysadmin. Now, logins that already have a user in one of the databases are blocked, when users try to add the login to sysadmin role. Task: BABEL-3637 Signed-off-by: Ray Kim <[email protected]>
