-- # NAME
|
||||
--
|
||||
-- **Versioning** - simplistic take on tracking and applying changes to databases.
|
||||
--
|
||||
-- # DESCRIPTION
|
||||
--
|
||||
-- This project strives to provide simple way to manage changes to
|
||||
-- database.
|
||||
--
|
||||
-- Instead of making changes on development server, then finding
|
||||
-- differences between production and development, deciding which ones
|
||||
-- should be installed on production, and finding a way to install them -
|
||||
-- you start with writing diffs themselves!
|
||||
--
|
||||
-- # INSTALLATION
|
||||
--
|
||||
-- To install versioning simply run install.versioning.sql in your database
|
||||
-- (all of them: production, stage, test, devel, ...).
|
||||
--
|
||||
-- # USAGE
|
||||
--
|
||||
-- In your files with patches to database, put whole logic in single
|
||||
-- transaction, and use \_v.\* functions - usually \_v.register_patch() at
|
||||
-- least to make sure everything is OK.
|
||||
--
|
||||
-- For example. Let's assume you have patch files:
|
||||
--
|
||||
-- ## 0001.sql:
|
||||
--
|
||||
-- ```
|
||||
-- create table users (id serial primary key, username text);
|
||||
-- ```
|
||||
--
|
||||
-- ## 0002.sql:
|
||||
--
|
||||
-- ```
|
||||
-- insert into users (username) values ('depesz');
|
||||
-- ```
|
||||
-- To change it to use versioning you would change the files, to this
|
||||
-- state:
|
||||
--
|
||||
-- 0000.sql:
|
||||
--
|
||||
-- ```
|
||||
-- BEGIN;
|
||||
-- select _v.register_patch('000-base', NULL, NULL);
|
||||
-- create table users (id serial primary key, username text);
|
||||
-- COMMIT;
|
||||
-- ```
|
||||
--
|
||||
-- ## 0002.sql:
|
||||
--
|
||||
-- ```
|
||||
-- BEGIN;
|
||||
-- select _v.register_patch('001-users', ARRAY['000-base'], NULL);
|
||||
-- insert into users (username) values ('depesz');
|
||||
-- COMMIT;
|
||||
-- ```
|
||||
--
|
||||
-- This will make sure that patch 001-users can only be applied after
|
||||
-- 000-base.
|
||||
--
|
||||
-- # AVAILABLE FUNCTIONS
|
||||
--
|
||||
-- ## \_v.register_patch( TEXT )
|
||||
--
|
||||
-- Registers named patch, or dies if it is already registered.
|
||||
--
|
||||
-- Returns integer which is id of patch in \_v.patches table - only if it
|
||||
-- succeeded.
|
||||
--
|
||||
-- ## \_v.register_patch( TEXT, TEXT[] )
|
||||
--
|
||||
-- Same as \_v.register_patch( TEXT ), but checks is all given patches (given as
|
||||
-- array in second argument) are already registered.
|
||||
--
|
||||
-- ## \_v.register_patch( TEXT, TEXT[], TEXT[] )
|
||||
--
|
||||
-- Same as \_v.register_patch( TEXT, TEXT[] ), but also checks if there are no conflicts with preexisting patches.
|
||||
--
|
||||
-- Third argument is array of names of patches that conflict with current one. So
|
||||
-- if any of them is installed - register_patch will error out.
|
||||
--
|
||||
-- ## \_v.unregister_patch( TEXT )
|
||||
--
|
||||
-- Removes information about given patch from the versioning data.
|
||||
--
|
||||
-- It doesn't remove objects that were created by this patch - just removes
|
||||
-- metainformation.
|
||||
--
|
||||
-- ## \_v.assert_user_is_superuser()
|
||||
--
|
||||
-- Make sure that current patch is being loaded by superuser.
|
||||
--
|
||||
-- If it's not - it will raise exception, and break transaction.
|
||||
--
|
||||
-- ## \_v.assert_user_is_not_superuser()
|
||||
--
|
||||
-- Make sure that current patch is not being loaded by superuser.
|
||||
--
|
||||
-- If it is - it will raise exception, and break transaction.
|
||||
--
|
||||
-- ## \_v.assert_user_is_one_of(TEXT, TEXT, ... )
|
||||
--
|
||||
-- Make sure that current patch is being loaded by one of listed users.
|
||||
--
|
||||
-- If ```current_user``` is not listed as one of arguments - function will raise
|
||||
-- exception and break the transaction.
|
||||
|
||||
BEGIN;
|
||||
|
||||
-- This file adds versioning support to database it will be loaded to.
|
||||
-- It requires that PL/pgSQL is already loaded - will raise exception otherwise.

-- All versioning "stuff" (tables, functions) is in "_v" schema.
|
||||
|
||||
-- All functions are defined as 'RETURNS SETOF INT4' to be able to make them to RETURN literally nothing (0 rows).
