sqitch-checkout - Revert, checkout another VCS branch, and re-deploy changes
sqitch checkout [options] [<database>] <branch>
Checkout another branch in your project's VCS (such as git), while performing the necessary database changes to update your database for the new branch.
More specifically, the checkout command compares the plan in the current branch to that in the branch to check out, identifies the last common changes between them, reverts to that change as if sqitch revert was called (unless there have been no changes deployed since that change), checks out the new branch, and then deploys all changes as if sqitch deploy had been called.
checkout
sqitch revert
sqitch deploy
If the VCS is already on the specified branch, nothing will be done.
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.
<database>
--target
-t
The target database to which to connect. This option can be either a URI or the name of a target in the configuration.
--mode
Specify the reversion mode to use in case of failure. Possible values are:
all
In the event of failure, revert all deployed changes, back to the point at which deployment started. 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 during this deployment, all changes will be reverted to the point at which deployment began.
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. 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".
name=value
--set defuser='Homer Simpson'
-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, but without actually running the deploy scripts. Useful for an existing database that is being converted to Sqitch, and you need to log changes as deployed because they have been deployed by other means in the past.
--lock-timeout
sqitch checkout --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 checkout --registry registry
The name of the Sqitch registry schema or database in which sqitch stores its own data.
--db-client
--client
sqitch checkout --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 checkout --db-name widgets sqitch checkout -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 checkout --db-username root sqitch checkout --db-user postgres sqitch checkout -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 checkout --db-host db.example.com sqitch checkout -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 checkout --db-port 7654 sqitch checkout -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 checkout --plan-file my.plan
Path to the deployment plan file. Overrides target, engine, and core configuration values. Defaults to $top_dir/sqitch.plan.
[deploy.variables]
[revert.variables]
A section defining database client variables. These variables are useful if your database engine supports variables in scripts, such as PostgreSQL's psql variables, Vertica's vsql variables, MySQL's user variables, SQL*Plus's DEFINE variables, and Snowflake's SnowSQL variables.
psql
vsql
DEFINE
May be overridden by --set, --set-deploy, --set-revert, or target and engine configuration. Variables are merged in the following priority order:
Used only while reverting changes.
Used only while deploying changes.
Used while reverting and deploying changes.
target.$target.variables
engine.$engine.variables
revert.variables
deploy.variables
core.variables
checkout.verify
deploy.verify
Boolean indicating whether or not to verify each change after deploying it.
checkout.mode
deploy.mode
Deploy mode. The supported values are the same as for the --mode option.
[checkout.no_prompt]
[revert.no_prompt]
A boolean value indicating whether or not to disable the prompt before executing the revert. The checkout.no_prompt variable takes precedence over revert.no_prompt, and both may of course be overridden by -y.
checkout.no_prompt
revert.no_prompt
[checkout.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 checkout.prompt_accept variable takes precedence over revert.prompt_accept, and both default to true, meaning to accept the revert.
checkout.prompt_accept
revert.prompt_accept
[checkout.strict]
[revert.strict]
A boolean value that, when true, disables the checkout command. The checkout.strict variable takes precedence over revert.strict.
checkout.strict
revert.strict
When the checkout command is disabled, use the deploy and revert commands directly.
deploy
revert
