sqitch-rebase - Revert and redeploy database changes

  sqitch [options] rebase [<database>]
  sqitch [options] rebase [<database>] --onto-change <change>
  sqitch [options] rebase [<database>] --onto-change <change> --upto-change <change>
  sqitch [options] rebase [<database>] <change>
  sqitch [options] rebase [<database>] <change> --upto-change <change>
  sqitch [options] rebase [<database>] <change> <change>

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.

"-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.
"--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 the "deploy.variables" or "revert.variables" configurations.
"-d"
"--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 loaded from the "deploy.variables" configuration.
"-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 loaded from the "deploy.variables" and "revert.variables" configurations.
"--log-only"
Log the changes as if they were deployed and reverted, but without actually running the deploy and revert scripts.
"-y"
Disable the prompt that normally asks whether or not to execute the revert.

"[deploy.variables]"
"[revert.variables]"
A section defining database client variables. The "deploy.variables" configuration is read from the "deploy" command configuration, on the assumption that the values will generally be the same. If they're not, use "revert.variables" to override "deploy.variables".
These variables are Useful if your database engine supports variables in scripts, such as PostgreSQL's "psql" variables <http://www.postgresql.org/docs/current/static/app-psql.html#APP-PSQL-INTERPOLATION>, Vertica's "vsql" variables <http://my.vertica.com/docs/7.1.x/HTML/index.htm#Authoring/ConnectingToHPVertica/vsql/Variables.htm>, MySQL's user variables <http://dev.mysql.com/doc/refman/5.6/en/user-variables.html>, and SQL*Plus's "DEFINE" variables <http://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12017.htm>.
"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.

Part of the sqitch suite.
