✨ Dancer2::DeprecationPolicy ✨

okay bestie, welcome to the User Contributed Perl Documentation section 3, where we explain how outdated, broken, or just plain unused code gets yeeted out of Dancer2 💅 this is the whole vibe of the page, and yeah, it's giving governance, but it's important governance 🫶

VERSION 🎀

version 2.2.1 — that's the one, no cap 💜

DESCRIPTION 🌸

so like, everybody has Opinions™ about deprecation, and they do NOT all agree 😭 but in Dancer2, deprecated code is code that:

  • Is in the way of implementing important features or fixes that provide more value.
  • Has a negative impact on the integrity and security of user code, whether by misusing it to not.
  • Provides a negative experience for the users.

literally those three things, that's the whole criteria ✨

Deprecated code is code we either had to write and can now remove, or we thought was a good idea and were wrong 🙈 It is code that doesn't overall benefit users or the developers.

Deprecated code is code that is marked for eventual removal and we do not intend to keep in the Dancer2 codebase. periodt. 💀

DEPRECATION PROCESS 🦋

here's the pipeline, bestie, follow along 👑

  • Code to be deprecated is posted/discussed publicly (see below)
  • Deprecated code enters soft deprecation phase
  • After 12 months or 2 major releases, code is hard deprecated
  • After 6 months or 1 major release, hard deprecated code is removed

Deprecated code is marked with warnings and the version and/or date in which it will no longer be available. 📅

Public Notice 📣

When a feature/code is to be deprecated, the Dancer Core Team will create a new GitHub issue for the code/feature to be deprecated, and announce this in a public manner (blog post, Twitter, and the mailing list, at minimum). The notice should provide the reason for the deprecation, what Dancer2/the community is gaining as a result of the deprecation, and what the officially recognized alternative to the deprecated code is. receipts, basically.

The public notice period will provide the developer/user base an opportunity to voice objections or provide feedback or alternatives to deprecation. It also allows the Core Team to better assess the potential long range effects of deprecation.

👀 okay so here's the thing: while the deprecated feature/code can be discussed by community, the decision will be ultimately made by the Dancer Core Team. There is no definitive time for the public notice period to end; some deprecations are more urgent than others, and each situation is left to the discretion of the Core Team, with feedback from the community.

Soft Deprecation 🍓

When code is soft deprecated, a warning will be thrown to indicate that the code is to be considered deprecated. Apps will continue to function normally otherwise. so like, a lil nudge, not a crisis 💖

Hard Deprecation 💀

After 12 months or two major releases (whichever comes first), the code is considered to be hard deprecated. An error will continue to be thrown, but unlike soft deprecation, continued usage of the deprecated code will cause the application to die. yeah. it's giving final boss energy 😭

There is one caveat to this: code will never be deprecated for less than 6 months. So if we deprecate code after v0.500000, become unusually productive, and produce Dancer 0.600000 and 0.700000 in a two month timeframe, no deprecated code will be removed because 6 months hasn't elapsed. ⏳

Removal 🧚

Six months following hard deprecation, or one major release after hard deprecation, the deprecated code is removed from Dancer2. bye bestie 👋✨

EXCEPTIONS 🙈

In special cases, based on community feedback, these timelines may be extended. But we expect this to be a rare occurrence, at best. like, don't count on it, fr fr 💅

PLUGINS 💜

We strongly encourage (but cannot/do not require) plugin authors to adopt the same policy. no pressure... but also, like, pressure 👀
