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 $top_dir/sqitch.plan.
Configuration Variables
"[deploy.variables]"
"[revert.variables]"
A section defining database client variables. These variables are useful if your
database engine supports variables in scripts, such as PostgreSQL's "psql" variables
<https://www.postgresql.org/docs/current/static/app-psql.html#APP-PSQL-INTERPOLATION>,
Vertica's "vsql" variables
<https://my.vertica.com/docs/7.1.x/HTML/index.htm#Authoring/ConnectingToHPVertica/vsql/Variables.htm>,
MySQL's user variables <https://dev.mysql.com/doc/refman/5.6/en/user-variables.html>,
SQL*Plus's "DEFINE" variables
<https://docs.oracle.com/cd/B19306_01/server.102/b14357/ch12017.htm>, and Snowflake's
SnowSQL variables <https://docs.snowflake.com/en/user-guide/snowsql-use.html#using-
variables>.
May be overridden by "--set", "--set-deploy", "--set-revert", or target and engine
configuration. Variables are merged in the following priority order:
"--set-revert"
Used only while reverting changes.
"--set-deploy"
Used only while deploying changes.
"--set"
Used while reverting and deploying changes.
"target.$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.
