Subject: [PATCH] `cabal-check` testsuite: add Package/File tests (#8250)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* (cabal check) Add “Unknown OS†test
* (cabal check) Add “Unknown arch†test
* (cabal check) Add “Unknown compiler†test
* (cabal check) Add “Package versions†check
* (cabal check) Add “`-Werror`†test
* (cabal check) Add “-j[n]†test
* (cabal check) Add “Defer type errors†test
* (cabal check) Add “Debug flag†test
* (cabal check) Add “Profiling flag†test
* (cabal check) Add “Unused flag†test
* (cabal check) Add “Custom fields†check
* (cabal check) Add “Paths_module extension†test
* (cabal check) Add “Setup bounds†test
* (cabal check) Add “Duplicate module†test
* (cabal check) Add “No license†check
* (cabal check) Add “NONE license†test
* (cabal check) Add AllRightsReserved warning test
* (cabal check) Add “compatibility†license test
With cabal-version < 1.4, some license (e.g. ISC) mess up the
parser.
* (cabal check) Add “Unknown license†test
* (cabal check) Add “Suspicious BSD4†test
* (cabal check) Add “Suspicious version†test
* (cabal check) Add “`license-file` missing†test
* (cabal check) Add “Unrecognised repo type†test
* (cabal check) Add “No `type`†test
* (cabal test) Add “No `location`†test
* (cabal check) Add “No `module`†test
Only for CVS repos.
* (cabal check) Add “`tag` needed†test
For `this`-type source-repositories.
* (cabal check) Add “Relative path†test
* (cabal check) Add “Good relative path†test
* (cabal check) Add “ghc-options†test.
Checks if there is a tricky GHC option in `ghc-options`. We will
*not* write an integration test for each offending option, just
one (in this case for `-fasm`) to make sure the field is scanned.
* (cabal check) Add “ghc-shared-options†test.
Checks if there is a tricky GHC option in `ghc-shared-options`. We
will *not* write an integration test for each offending option, just
one (in this case for `-fglasgow-exts`) to make sure the field is
scanned.
* (cabal check) Add “ghc-prof-options†test.
Checks if there is a tricky GHC option in `ghc-prof-options`. We
will *not* write an integration test for each offending option,
just one (in this case for `-o`) to make sure the field is scanned.
* (cabal check) Add “`cc-options` include†test
* (cabal check) Add “Cxx `extra-libraries`†test
* (cabal check) Add “`cc-options` libdir†test
* (cabal check) Add `Cxx -Os` test.
* (cabal check) Add “Portable CPP flags†test
* (cabal check) Add “Invalid on Win†test
* (cabal check) Add “Outside relative path†test
Note that this test is not atomic; it comes with a "not a good
relative path" error, and this is unavoidable.
* (cabal check) Add “Absolute path†test.
Note that this test is not atomic; comes with a "not a good relative
path" *and* a "does not match any file" warning. This is unfortunately
unavoidable.
* (cabal check) Add “points to dist/†test
* (cabal check) Add “Testsuite ≥1.8†test
* (cabal check) Add “Default language†test
* (cabal check) Add “Default language spec†test
* (cabal check) Add “Extra doc†test
* (cabal check) Add “Multilib/namedlib†test
* (cabal check) Add “Reexported module†test
* (cabal check) Add “Mixins†test
* (cabal check) Add “Extra framework dirs†test
* (cabal check) Add “Default extensions†test
* (cabal check) Add `extensions` test
* (cabal check) Add Sources test
* (cabal check) Add “Extra libs†test
* (cabal check) Add “Virtual modules†test
* (cabal check) Add “Source repository†test
* (cabal check) Add “Extension break†test

* (cabal check) Add “Language as extension†test
Languages cannot be listed in `default-extensions`.
* (cabal check) Add “Deprecated extension†test
* (cabal check) Add “No synopsis†test
* (cabal check) Add “No description†test
* (cabal check) Add “No category†test
* (cabal check) Add “No maintainer†test
* (cabal check) Add “Short description†test
`description` should be longer than `synopsis`.
* (cabal check) Add “Invalid tested with range†test
* (cabal check) Add “Internal library†test
On impossible version ranges for internal libraries.
* (cabal check) Add BOM test
* (cabal check) Add “Name mismatch†test
* (cabal check) Add “Missing .cabal†test

Consider using 'cabal-version: 1.24' or higher and adding a 'custom-setup' section with a 'setup-depends' field that specifies the dependencies of the Setup.hs script itself. The 'setup-depends' field uses the same syntax as 'build-depends', so a simple example would be 'setup-depends: base, Cabal'.

+Warning: The 'description' field should be longer than the 'synopsis' field. It's useful to provide an informative 'description' to allow Haskell programmers who have never heard about your package to understand the purpose of your package. The 'description' field content is typically shown by tooling (e.g. 'cabal info', Haddock, Hackage) below the 'synopsis' which serves as a headline. Please refer to <https://cabal.readthedocs.io/en/stable/cabal-package.html#package-properties> for more details.

+Warning: The following errors will cause portability problems on other environments:
+Warning: The dependency 'build-depends: base' does not specify an upper bound on the version number. Each major release of the 'base' package changes the API in various ways and most packages will need some changes to compile with it. The recommended practice is to specify an upper bound on the version of the 'base' package. This ensures your package will continue to build when a new major version of the 'base' package is released. If you are not sure what upper bound to use then use the next major version. For example if you have tested your package with 'base' version 4.5 and 4.6 then use 'build-depends: base >= 4.5 && < 4.7'.
