Description

Revert and redeploy changes to the database. It's effectively a shortcut for running sqitch revert and sqitch deploy in succession.

More specifically, starting from the current deployment state, changes will be reverted in reverse the order of application. All changes will be reverted unless a change is specified, either via --onto or with no option flag, in which case changes will be reverted back to that change. If nothing needs to be reverted, a message will be emitted explaining why and nothing will be reverted.

Once the revert finishes, changes will be deployed starting from the deployed state through the rest of the deployment plan. They will run to the latest change in the plan, unless a change is specified, either via --upto or with no option flag, in which case changes will be deployed up-to and including that change.

If the database has not been deployed to, or its state already matches the specified change, no reverts will be run. And if, at that point, the database is up-to-date, no deploys will be run.

The <database> parameter specifies the database to which to connect, and may also be specified as the --target option. It can be target name, a URI, an engine name, or plan file path.

Options

-t

--target

The target database to which to connect. This option can be either a URI or the name of a target in the configuration.

--onto-change

--onto

Specify the reversion change. Defaults to reverting all changes. See sqitchchanges for the various ways in which changes can be specified.

--upto-change

--upto

Specify the deployment change. Defaults to the last point in the plan. See sqitchchanges for the various ways in which changes can be specified.

-m

--modified

Finds the change to revert onto based on modifications to deploy scripts. Reverts the change prior to earliest change with a revised deploy script. Handy for quick rebases during iterative development cycles.

--mode

Specify the reversion mode to use in case of deploy failure. Possible values are:

all

In the event of failure, revert all deployed changes, back to --onto-change. This is the default.

tag

In the event of failure, revert all deployed changes to the last successfully-applied tag. If no tags were applied, all changes will be reverted to --onto-change.

change

In the event of failure, no changes will be reverted. This is on the assumption that a change is atomic, and thus may may be deployed again.

--verify

Verify each change by running its verify script, if there is one, immediate after deploying it. If a verify test fails, the deploy will be considered to have failed and the appropriate reversion will be carried out, depending on the value of --mode.

--no-verify

Don't verify each change. This is the default.

-s

--set

Set a variable name and value for use by the database engine client, if it supports variables. The format must be name=value, e.g., --set defuser='Homer Simpson'. Overrides any values loaded from "configuration Variables".

-e

--set-deploy

Set a variable name and value for use by the database engine client when deploying, if it supports variables. The format must be name=value, e.g., --set defuser='Homer Simpson'. Overrides any values from --set or values loaded from "configuration Variables".

-r

--set-revert

Sets a variable name to be used by the database engine client during when reverting, if it supports variables. The format must be name=value, e.g., --set defuser='Homer Simpson'. Overrides any values from --set or values loaded from "configuration Variables".

--log-only

Log the changes as if they were deployed and reverted, but without actually running the deploy and revert scripts.

--lock-timeout

sqitch rebase --lock-timeout 600

Set the number of seconds for Sqitch to wait to get an exclusive advisory lock on the target database, for engines that support such a lock. This lock prevents other instances of Sqitch from working on the target at the same time, but prevents no other database activity. Defaults to 60.

-y

Disable the prompt that normally asks whether or not to execute the revert.

--registry

sqitch rebase --registry registry

The name of the Sqitch registry schema or database in which sqitch stores its own data.

--db-client

--client

sqitch rebase --client /usr/local/pgsql/bin/psql

Path to the command-line client for the database engine. Defaults to a client in the current path named appropriately for the database engine.

-d

--db-name

sqitch rebase --db-name widgets
sqitch rebase -d bricolage

Name of the database. In general, targets and URIs are preferred, but this option can be used to override the database name in a target.

-u

--db-user

--db-username

sqitch rebase --db-username root
sqitch rebase --db-user postgres
sqitch rebase -u Mom

User name to use when connecting to the database. Does not apply to all engines. In general, targets and URIs are preferred, but this option can be used to override the user name in a target.

-h

--db-host

sqitch rebase --db-host db.example.com
sqitch rebase -h appdb.example.net

Host name to use when connecting to the database. Does not apply to all engines. In general, targets and URIs are preferred, but this option can be used to override the host name in a target.

-p

--db-port

sqitch rebase --db-port 7654
sqitch rebase -p 5431

Port number to connect to. Does not apply to all engines. In general, targets and URIs are preferred, but this option can be used to override the port in a target.

--plan-file

-f

sqitch rebase --plan-file my.plan

Path to the deployment plan file. Overrides target, engine, and core configuration values. Defaults to $top_dir/sqitch.plan.

Configuration Variables

[deploy.variables]

[revert.variables]

A section defining database client variables. These variables are useful if your database engine supports variables in scripts, such as PostgreSQL's psql variables, Vertica's vsql variables, MySQL's user variables, SQL*Plus's DEFINE variables, and Snowflake's SnowSQL variables.

May be overridden by --set, --set-deploy, --set-revert, or target and engine configuration. Variables are merged in the following priority order:

--set-revert

Used only while reverting changes.

--set-deploy

Used only while deploying changes.

--set

Used while reverting and deploying changes.

target.$target.variables

Used while reverting and deploying changes.

engine.$engine.variables

Used while reverting and deploying changes.

revert.variables

Used only while reverting changes.

deploy.variables

Used while reverting and deploying changes.

core.variables

Used while reverting and deploying changes.

rebase.verify

deploy.verify

Boolean indicating whether or not to verify each change after deploying it.

rebase.mode

deploy.mode

Deploy mode. The supported values are the same as for the --mode option.

[rebase.no_prompt]

[revert.no_prompt]

A boolean value indicating whether or not to disable the prompt before executing the revert. The rebase.no_prompt variable takes precedence over revert.no_prompt, and both may of course be overridden by -y.

[rebase.prompt_accept]

[revert.prompt_accept]

A boolean value indicating whether default reply to the prompt before executing the revert should be "yes" or "no". The rebase.prompt_accept variable takes precedence over revert.prompt_accept, and both default to true, meaning to accept the revert by default.

[rebase.strict]

[revert.strict]

A boolean value that, when true, disables the revert command. The revert.strict variable takes precedence over revert.strict.

Sqitch

Part of the sqitch suite.
