 # Revision history for ghcup

-## 0.1.22.0 -- 2024-03-13
-
-### New features
-
-* A help screen/tutorial in the TUI by @lsmor (Luis Morillo)
-* Beef up `--overwrite-version`, fixes [#998](https://github.com/haskell/ghcup-hs/issues/998)
-  * e.g. `ghcup compile hls -g master --overwrite-version='%v-%h' --ghc 9.4.8` will produce a binary called `haskell-language-server-wrapper-<version-from-cabal-file>-<short-git-commit-hash>`... refer to `ghcup compile hls --help` for more information
-* Allow to set ghcup msys2 environment wrt [#982](https://github.com/haskell/ghcup-hs/issues/982)
-* Add mechanism to warn on new metadata versions, fixes [#860](https://github.com/haskell/ghcup-hs/issues/860)
-* Add pre-install message support via ghcup metadata, wrt [#1016](https://github.com/haskell/ghcup-hs/issues/1016)
-* Allow to remove all unset versions, fixes [#1019](https://github.com/haskell/ghcup-hs/issues/1019)
-  * e.g.: `ghcup gc --unset`
-
-### Improvements and bug fixes
-
-* Fix potential [HSEC-2024-0002](https://haskell.github.io/security-advisories/advisory/HSEC-2024-0002.html)
-* Fix TUI crash in windows terminal 1.19 [#1013](https://github.com/haskell/ghcup-hs/issues/1013)
-* Clean up on git clone errors, fixes [#1004](https://github.com/haskell/ghcup-hs/issues/1004)
-* Error out on empty UserSettings wrt [#922](https://github.com/haskell/ghcup-hs/issues/922)
-* Fix failure mode when metadata is garbage, fixes [#921](https://github.com/haskell/ghcup-hs/issues/921)
-* Be less confusing when user tries to 'set' ghcup in TUI, fixes [#923](https://github.com/haskell/ghcup-hs/issues/923)
-* Fix prefetch for cross bindists
-* Fix misinterpretation of '+' in URI paths, fixes [#408](https://github.com/haskell/ghcup-hs/issues/408)
-* Stricter (and better) file uri handling
-* Set LD=ld.bfd on Alpine linux during bindist configure
-* Add rocky/void detection
-* Logging improvements
-* Remove the "show all tool" config in the TUI
-* Fix opening changelog on windows
-* Don't remove share dir link prematurely
-* Require user to explicitly choose subcommand for 'ghcup config'
-* Don't download twice when trying stack decoding
-
-### Refactoring and maintenance
-
-* Large TUI code cleanup by @lsmor (Luis Morillo)... more coming up soon
-* Allow building with `tar` instead of `libarchive` (mainly to make contributions easier)
-
-## 0.1.20.0 -- 2023-11-10
-
-### New features
-
-* support TUI on windows thanks to the work from vty and brick maintainers (Chris Hackett, Timofey Zakrevskiy, Jonathan Daugherty, ...), wrt [#912](https://github.com/haskell/ghcup-hs/pull/912)
-* support JS and wasm cross compilers wrt [#838](https://github.com/haskell/ghcup-hs/issues/838), thanks to Sylvain Henry and IOG
-* Support stacks installation strategy and metadata wrt [#892](https://github.com/haskell/ghcup-hs/issues/892)
-  - you can now enable stacks installation method via `ghcup config set url-source '["GHCupURL", "StackSetupURL"]'`... for more information, check the [documentation](https://www.haskell.org/ghcup/guide/#using-stacks-setup-info-metadata-to-install-ghc)
-
-### Improvements and bug fixes
-
-* fix segfault in TUI when hitting enter early wrt [#887](https://github.com/haskell/ghcup-hs/issues/887)
-* Improve key handling in TUI, fixes [#875](https://github.com/haskell/ghcup-hs/issues/875)
-* add explicit support for Void Linux and Rocky Linux (this requires a metadata version bump to `ghcup-0.0.8.yaml`)
-* optparse cli interface now has a test suite thanks to Lei Zhu, wrt [#862](https://github.com/haskell/ghcup-hs/pull/862)
-
-## 0.1.19.4 -- 2023-7-02
-
-* fix missing TUI for aarch64 linux binaries

-
-## 0.1.19.2 -- 2023-2-24
-
-* Follow-up fix for JFS/ReiserFS and other filesystem that don't support `d_type`, fixes [#787](https://github.com/haskell/ghcup-hs/issues/787)
-    - the previous release had a bug that invalidated that broke it
-* Implement 'latest-prerelease' tag wrt [#788](https://github.com/haskell/ghcup-hs/issues/788)
-* Fix 'Could not parse version of stray directory.DS_Store' warnings on macOs wrt [#797](https://github.com/haskell/ghcup-hs/issues/797)

+# TODOs and Remarks
+
+## Now
+
+* ghcup init?
+* merge two download files
+* fetch/unpack functionality
+* installing multiple versions of the same
+* post-install
+
+* proper test suite
+
+* !! update of 0.1.5 must go in ghcup-0.0.1.json !!
+
+* try to run exe before upgrade (backup to ~/.ghcup/bin/ghcup.old)
+* stdout flushing?
+* resume support (for make-install only)
+
+## Maybe
+
+* version ranges in json
+* sign the JSON? (Or check gpg keys?)
+* testing (especially distro detection -> unit tests)
+
+## Later
+
+* add support for RC/alpha/HEAD versions
+
+## Cleanups
+
+* avoid alternative for IO
+* use plucky or oops instead of Excepts
+
+## Questions
+
+* move out GHCup.Version module, bc it's not library-ish?
+* mirror support
+* interactive handling when distro doesn't exist and we know the tarball is incompatible?
+* ghcup-with wrapper to execute a command with a given ghc in PATH?

-## Project ownership and hierarchy
-
-The project at the time of writing (2024-04-22) follows the model of
-[benevolent dictator for life](https://en.wikipedia.org/wiki/Benevolent_dictator_for_life), which is
-Julian Ospald at the moment.
-
-Ideally, the ownership should be shared across a core team of collaborators sharing the same vision and
-engagement in the future.
-
-I do not believe in people making decisions over projects they are barely involved in. Instead I believe
-in listening to end users needs very carefully and making decisions based on that. People who want a direct
-influence on the decision process have to both demonstrate they share the vision of GHCup and do the actual
-work.
-
-"Work" here doesn't have to be "writing code". There are many ways to be engaged in a project.
-
-### Transition plan in case of maintainer absence
-
-In case the current maintainer of GHCup (Julian Ospald) is unreachable for a prolonged period of time (3 months),
-the ownership of this project will be automatically transferred to the following individuals:
-
- [Moritz Angerman](https://github.com/angerman)
- [Andrew Lelechenko](https://github.com/Bodigrim)
-
-They will be tasked with finding new maintainers in whatever way they see fit (be it appointing themselves or asking HF for help).
-
-The appointed owners may choose to stay owners after the transition period (whether it's in a passive or active capacity) or
-fully transfer ownership to someone else or an organization.
-
-The community shall be informed about this process.
-
-If not otherwise specified by the newly appointed owners, the following principles shall apply to the *transition period*:
-
-#### During the transition period
-
-During the transition period, no other individual or organization is allowed to drive changes to
-[ghcup-hs](https://github.com/haskell/ghcup-hs) repository, unless they are explicitly allowed to do so by the appointed owners.
-
-The following people (in addition to the owners) shall have full write access to the
-[ghcup-metadata](https://github.com/haskell/ghcup-metadata) repository
-(all files) for the length of the transition period, unless otherwise specified by the appointed owners:
-
- [Ben Gamari](https://github.com/bgamari)
- [Hécate Moonlight](https://github.com/Kleidukos)
- [Mike Pilgrem](https://github.com/mpilgrem)
- [Jens Petersen](https://github.com/juhp)
-
-Contributions to the metadata are expected to follow a review process. If that turns out to be impractical due to lack of engagement, a wait
-time of 2 days before merging shall be followed anyway, except for the `-vanilla` files, which may be merged at any time.
-
-#### Access
-
-The GHCup website, various scripts and unofficial bindists are hosted on haskell.org infrastructure. Contact the
-[Haskell.org committee](https://www.haskell.org/haskell-org-committee/) for access.
-
-The backup owners should already have admin rights on the GHCup repositories, which are hosted on the
-[Github haskell namespace](https://github.com/haskell). In case of issues contact one of the
-organization admins for access, e.g.:
-
- [Andrew Lelechenko](https://github.com/orgs/haskell/people/Bodigrim)
- [gbaz](https://github.com/orgs/haskell/people/gbaz)
- [Hécate Moonlight](https://github.com/Kleidukos)
- [davean](https://github.com/orgs/haskell/people/davean)
- [chessai](https://github.com/orgs/haskell/people/chessai)
-
-The owners should already have access to the [hackage package](https://hackage.haskell.org/package/ghcup/maintainers/).
-In case of issues contact the [hackage trustees](https://github.com/haskell-infra/hackage-trustees).
-
-#### Private runners
-
-Private runners maintained by Julian Ospald may cease to work. Moritz Angerman will have SSH access to the machines.
-However, no one will have access to the Hetzner account and billing information. As such, those runners will simply
-have to be replaced.
-
