Ahead of the release of Sqitch v1.0 sometime in 2019, I’d like to remove all the deprecated features and code paths. Before I do, I want to get a sense of the impact of such removals. So here’s a comprehensive list of the deprecations currently in Sqitch, along with details on their replacements, warnings, and updates. If the removal of any of these items would create challenges for your use Sqitch, get in touch.
What would be removed:
The core configuration and directory-specification options and attributes:
The preferred solution is configuration values at the target, engine, or core level (settable via the options on the
initcommands, or via the
But I admit that there are no overriding options for the directory configurations in the deploy/revert/verify/rebase/checkout commands. And I’ve used
--top-dirquite a lot myself! Perhaps those should be added first. If we were to add those, I think it’d be okay to remove the core options — especially if I ever get around to merging options to allow both core and command options to be specified before or after the command name.
@LASTsymbolic tags, which were long-ago supplanted by the more Git-like
@HEAD, and warnings have been emitted for at least some of their uses for six years now.
Engine configuration under
core.$engine. This configuration was supplanted by
engine$enginefour years ago, and came with warnings, and a fix via the
sqitch engine update-configaction. That action would also go away.
The core database connection options:
These options were supplanted by database URIs over four years ago. At that time, they were adapted to override parts of target URIs. For example, if you have a target URI of
db:pg://db.example.com/flipr, you can specify that target, but then also pass
--db-nameto just change the database name part of the URI. I’ve found this occasionally useful, but I don’t think the complexity of the implementation is worth it.
The old target options, which were renamed “change” targets back when the term “target” was adopted to refer to databases rather than changes. Sqitch has emitted warnings for five years when the old names were used:
The script-generation options on the
addcommand were deprecated four years ago in favor of
--withoutoptions, with warnings for the old usages:
The same change replaced the template-specification options with a single
The corresponding config variables,
add.verify_templatewere replaced with a config section,
add.templates. No warnings were issued for the old names, though.
The data hashed to create change IDs was modified six years ago. At that time, code was added to update old change IDs in Postgres databases; no other engines were around at the time.
If removing any of these features would cause trouble for you or the organizations you know to be using Sqitch, please get in touch.
