It's pretty funny that it doesn't like aligning braces. I wonder if that's configurable.
I have no hard opinion on this but I kinda liked the aligning. Of course, it's painful to modify...

It's actually part of the diff reducing. You don't want that kind of extra noise when adding a new pragma during the review. :)

I mean I kinda don't but I'd be willing to trade this for pleasant reading. And i read code much more often than doing reviews.
Anyways, curious what others think.

Aligned braces are pretty and suck to maintain. It's not more pleasant imo - it just satisfies a particular "oo this aligns" feeling that doesn't actually contribute to legibility.

Another example where it's easier to read when vertically aligned. I guess, this kind of thing is what Andreas had alluded to.

Yes it's always a matter of tradeoff: Are you privileging vertical readability or minimising diffs in PRs? As PR diffs are our primary interface with new code, this is the path I've chosen
There was a problem hiding this comment.
I think the former (readability). But if there's a vast support for the latter, i will happily take it.
There was a problem hiding this comment.
The diffs in LANGUAGE pragmas and export lists never bothered me tbh. In the code they're occasionally annoying but not very often either.

Remember that you can locally turn off (f)ormolu if you want to preserve alignment in some places.

apparently there is a diff-friendly style which I don’t find more friendly than leading.

It's friendly when modifying the beginning of the import/export list. Admittedly perhaps not a common use-case, but nice when it happens

Are blanks after { and before } configurable? Perhaps, I'd prefer having them.

Uh good question. @brandonchinn178 Do you think this is something that could be easily added by a newcomer?

Sure thing! We already have record-brace-space for a space between constructor and brace, it's just a matter of adding an option for a space between brace and brace contents. Shouldnt be too difficult

Thank you @emilypi for phrasing it like this. |

FWIW I've found you can sometimes be clever to avoid disable pragmas; e.g. have two modules exposing the same function for two GHC versions, then CPP guard importing one of the modules. It's more work, but it can also encourage better encapsulation over cross-version implementations. Cabal is perhaps too old/complex of a codebase to do this for, but just wanted to throw this out there. For an example of this in practice, see my tasty-autocollect project |

@brandonchinn178 Thanks a lot for this tip. :) |

CCompilerOverride, was attempting to use gcc.exe rather than clang.exe without also overriding the C options which led to incorrect options being passed to gcc.exe. The fix is to override to clang.exe on ghc-9.4 or newer. 2. ForeignLibs exposes a bug in GHC (https://gitlab.haskell.org/ghc/ghc/-/issues/24185) and hence is skipped for GHCs newer than 9.4 where it was first introduced. Towards fixing #8451, we just need to fix the shared library issue now. * testsuite: Be explicit about runtime test dependencies Issue #8356 reports occasional errors from running the testsuite about multiple package versions available. This stems from the invokation of `runghc` not being explicit about all dependencies of the testsuite. The solution is provide a component in the cabal file which is explicit about which packages the tests can depend on. This component has a build-depends section which lists all the dependencies that the tests require. It would be better if this component was a library component but we can't do this with a Custom setup because of limitations to do with per-component builds. Then we also enable `-hide-all-packages`, so the dependency will not be available if it is not explicitly listed as a dependency. You could also imagine a future where the Setup.hs script found the test files and compiled a single executable which would run all the tests, rather than invoking runghc on each one individually. Fixes #8356 * hurd: Enable using $ORIGIN in RPATH GNU/Hurd fully supports RPATH and the $ORIGIN development, and we indeed want to use it for relocatable installations shipped in Debian GNU/Hurd. * Fix the platform string for GNU/Hurd Since version 9.4.7-1, ghc fails to build on the GNU/Hurd port of Debian, see https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=hurd-i386&ver=9.4.7-1&stamp=1697717885&raw=0 Error, rule finished running but did not produce file: _build/stage0/lib/i386-gnu-ghc-9.4.6/ghc-boot-th-9.4.7/libHSghc-boot-th-9.4.7.a and indeed, what did get produce was rather _build/stage0/lib/i386-hurd-ghc-9.4.6/ghc-boot-th-9.4.7/libHSghc-boot-th-9.4.7.a (i386-hurd instead of i386-gnu). This is due to confusion between hurd and gnu in various places. Apparently previous versions of ghc were using gnu for the GNU/Hurd port, and thus putting libraries etc. in i386-gnu. So we have to follow the existing practice. * Fix configuation of ldProgram Standard GNU `ld` ues `--relocatable` while `ld.gold` uses a `-relocatable` flag (with a single `-`). Code will now detect both versions. * Chain configuration of ldProgram `ldProgram` gets configured in two places, a seemingly default and a GHC specific version. The later needs to be updated so that it first calls the default configuration and then the new GHC version. * Use linker capability detection to improve linker use The function `comperSupportsGhciLibs` has been renamed to `linkerSupportsGhciLibs` because its about the linker not the compiler. The function `comperSupportsGhciLibs` was using the compiler version as a proxy for whether the linker supports relocatable objects. Now support for relocatable objects is detected by running the linker. * add `merge+no rebase` and a few typos while reviewing * Add support for 64-bit SPARC as a separate architecture Previously, sparc64 was defined as an alias for the 32-bit SPARC architecture which was true while SPARC mainland was mostly 32 bits. More recently, 64-bit SPARC has become a port of its own, so it needs to be treated as a separate architecture. * Remove debug-conflict-sets flag from solver package Fixes #8937. The debug-conflict-sets build flag probably hasn't been used for a long time, and it isn't currently tested. This commit removes the flag, converts the ConflictSet type back to a newtype, and removes an unnecessary instance. * Finish improvements to the CI configuration for documentation changes (#9460) * Add bootstrap postjob to CI config Add a new job to the bootstrap.yml GitHub action config. This job succeeds if, and only if, all the other bootstrap jobs succeed. * Do not run bootstrap CI jobs for documentation changes The approach was already introduced in #9355 for the validate jobs. This commit introduces the same change also for the bootstrap jobs. * Also ignore CONTRIBUTING.md and README.md in CI We do not run the entire CI suite for documentation changes. Previously, only changes which were restricted to the 'docs/' subdirectory were considered to be documentation changes. With this commit we also recognize changes to README.md and CONTRIBUTING.md as documentation changes. * Document improved CI for documentation in CONTRIBUTING.md The CONTRIBUTING.md file now mentions that documentation changes do not waste expensive CI resources. * Recognize all README.md in subdirs as documentation Expensive CI jobs should not run on changes which affect only README.md files. * formatting: Add style-commit makefile target This target allows you to format a range of commits, for example: ``` make style-commit COMMIT=HEAD~1 > Last commit is formatted make style-commit COMMIT=abcde > Commits between HEAD and abcde are formatted ``` * Fix assertion failure when combining build-tool-depends and --enable-documentation The `setDocumentation` function was modifying the elaborated package after the hash was computed. This led to the assertion failing as the computed hash was different to what was computed in the initial install plan. Therefore in order to fix this we either needed to: 1. Set elabBuildHaddocks = False at the point where the hash is initially computed. 2. Verify that elabBuildHaddocks = True will not lead to unexpected results. The latter has been implemented. The elabBuildHaddocks option is only consulted in `hasValidHaddockTargets`, at which point documentation building the executable component is disabled because elabHaddockExecutables is False. In the added test we ensure this by checking that we didn't build documentation for the executable which is built because of build-tool-depends. Fixes #6006 #8313 * testsuite: Improve error message in findDependencyInStore * Only move code to Simple/GHC/Build* * CPP mingw32_HOST_OS for more imports * cabal-install-solver: fix pkgconf 1.9 --modversion regression Check that the numbers of *versions* output is equal to the number of pkgconf's fixes #8923 The pkgconf behavior was reverted upstream in 2.0 (this should cover the case too of checking that equal pkgList lines are output also) * External commands: Add tests for #9402 #9403 #9404 This adds 4 tests which test the new external commands feature: * ExternalCommand - Tests the expected usage of external command invoked via cabal-install * ExternalCommandSetup - Tests that the ./Setup interface does not support external commands (#9403) * ExternalCommandEnv - Tests that environment variables are set and preserved appropiately (#9402) * ExternalCommandHelp - Test that `cabal help <cmd>` is interpreted appropiately (#9404) * Finish off the external commands feature * Remove 'CommandDelegate' in favour of abstracting the fallback in 'commandsRun', there is a new variant 'commdandRunWithFallback' which takes a continuation - This restores the modularity between the `Cabal` library and `cabal-install` as now `Cabal` doesn't need to know anything about the external command interface. - Fixes #9403 * Set the $CABAL environment variable to the current executable path - This allows external commands to be implemented by calling $CABAL, which is strongly preferred to linking against the Cabal library as there is no easy way to guantee your tool and `cabal-install` link against the same `Cabal` library. - Fixes #9402 * Pass the name of the argument - This allows external commands to be implemented as symlinks to an executable, and multiple commands can be interpreted by the same executable. - Fixes #9405 * `cabal help <cmd>` is interpreted as `cabal-<cmd> --help` for external commands. - This allows the `help` command to also work for external commands and hence they are better integrated into cabal-install. - Fixes #9404 The tests are updated to test all these additions. These features bring the external command interface up to par with the cargo external command interface. * Use Base16 hash for script path. Issue #9334 shows that `%` characters on Windows result in invalid paths, also `/` characters on Linux create invalid paths. This changes from using base64 to using base16 with the same length we use for unit-ids. * Migrate to haskell-actions/setup As of 2023-09-09, haskell/action/setup is no longer maintained. The comment # latest is mandatory for cabal-testsuite, see #8133 is removed; as the validate job was already fixing a version of cabal-install. * testsuite: Introduce Cabal-tests library for common testsuite functions I noticed that Distribution.Utils.TempTestDir was only used in the testsuite but defined in the Cabal library. Rather than expose this in the public interface of the `Cabal` library, it is cleaner to refactor it into a separate library (`Cabal-tests`) which can be used by any testsuite component. Also, in future it gives a clearer place to put utility functions which need to be shared across the testsuite but not exposed in Cabal. Cabal-tests can also freely add dependencies (such as exceptions) which we might want to avoid adding to the Cabal library. Fixes #9453 * GHC 9.8 compat: pacify -Wx-partial * GHC 9.8 compat: update hashes of data structures as computed by Structured It seems, GHC 9.8 changed something in the code generation for data types.

Set elabBuildHaddocks = False at the point where the hash is initially computed. 2. Verify that elabBuildHaddocks = True will not lead to unexpected results. The latter has been implemented. The elabBuildHaddocks option is only consulted in `hasValidHaddockTargets`, at which point documentation building the executable component is disabled because elabHaddockExecutables is False. In the added test we ensure this by checking that we didn't build documentation for the executable which is built because of build-tool-depends.

However, if the tests use a dependency, say 'directory', and there are two packages with the same unit id available in the store, the test fails since it doesn't know which one to pick. By including an extra dependency to directory, we force the test runner to use a specific version directory, fixing the test failure. * Use Paths_cabal_install for cabal-install version number (haskell#9421) * Use PackageInfo for cabal-install version number * Use Paths_cabal_install instead * Adjust documentation --------- Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> * Document --profiling-detail in setup-commands.

(review) Use guards instead of if/then/else (review) Match inside argument list (review) Replace “white” with “allow” (review) Fix typo in comment (review) Fix typo in Check module documentation (review) Harmonise indentation for `data` decls First field goes in a new line than the data constructor, so we have more space. (review) Rename `Prim` module to `Types` (review) Add checkPackageFilesGPD `checkPackageFiles` — which works on PD — was used to perform IO. We introduce a function that does the same thing but works on GPD (which is more principled). `checkPackageFiles` cannot just be removed, since it is part of the interface of Distribution.PackageDescription.Check. Deprecation can be planned once “new check” is up and running. * Integrate Andreas’ review (review) Add named section to missing upper bound check “miss upper bound” checks will now list target type and name (“On executable 'myexe', these packages miss upper bounds”) for easier fixing by the user. (review) remove `cabal gen-bounds` suggestion Reasonable as `cabal gen-bounds` is stricter than `cabal check`, see haskell#8427 (comment) Once `gen-bounds` behaves in line with `check` we can readd the suggestion. (review) Do not warn on shared bounds When a target which depends on an internal library shares some dependencies with the latter, do not warn on upper bounds. An example is clearer library build-depends: text < 5 ⁝ build-depends: myPackage, ← no warning, internal text, ← no warning, shared bound monadacme ← warning! * Integrate Artem’s review /II (review) Split Check.hs Check.hs has been split in multiple file, each une sub 1000 lines: Check 857 lines Check.Common 147 lines Check.Conditional 204 lines Check.Monad 352 lines Check.Paths 387 lines Check.Target 765 lines Check.Warning 865 lines Migration guide: - Check GPD/PD checks plus work-tree checks. - Check.Common common types and functions that are *not* part of monadic checking setup. - Check.Conditional checks on CondTree and related matter (variables, duplicate modules). - Check.Monad Backbone of the checks, monadic inter- face and related functions. - Check.Paths Checks on files, directories, globs. - Check.Target Checks on realised targets (libraries, executables, benchmarks, testsuites). - Check.Warning Datatypes and strings for warnings and severities. (review) remove useless section header (review) Fix typo (review) Add warnings documentation (list) For each warning, we document constructor/brief description in the manual. This might not be much useful as not but it will come handy when introducing `--ignore=WARN` and similar flags. * (review Andreas) Clarify CheckExplanation comment Whoever modifies `CheckExplanation` data constructors needs to be aware that the documentation in doc/cabal-commands.rst has to be updated too. * Move internal Check modules to `other-modules` No need to expose Distribution.PackageDescription.Check.* to the world. API for checking, for cabal-install and other tools, should be in Distribution.PackageDescription.Check. * Make fourmolu happy Cabal codebase has now a formatter/style standard (see haskell#8950). “Ravioli ravioli, give me the formuoli” * Do not check for OptO in scripts See haskell#8963 for reason and clarification requests. * Remove useless PackageId parameter It is now in the Reader part of CheckM monad. * Do not check PVP on internal targets Internal: testsuite, benchmark. See haskell#8361. * Make hlint happy * Fix haskell#9122 When checking internal version ranges, we need to make sure we are not mistaking a libraries with the same name but from different packages. See haskell#9132. * Fix grammar neither…nor, completing what done in haskell#9162 * Integrate Brandon’s review: grammar * Remove unnecessary `-fvia-C` check Brandon’s review/II. --------- Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> * ci: Enable windows tests for 9.6.3 There were two failing tests: 1. CCompilerOverride, was attempting to use gcc.exe rather than clang.exe without also overriding the C options which led to incorrect options being passed to gcc.exe. The fix is to override to clang.exe on ghc-9.4 or newer. 2. ForeignLibs exposes a bug in GHC (https://gitlab.haskell.org/ghc/ghc/-/issues/24185) and hence is skipped for GHCs newer than 9.4 where it was first introduced. Towards fixing haskell#8451, we just need to fix the shared library issue now. * testsuite: Be explicit about runtime test dependencies Issue haskell#8356 reports occasional errors from running the testsuite about multiple package versions available. This stems from the invokation of `runghc` not being explicit about all dependencies of the testsuite. The solution is provide a component in the cabal file which is explicit about which packages the tests can depend on. This component has a build-depends section which lists all the dependencies that the tests require. It would be better if this component was a library component but we can't do this with a Custom setup because of limitations to do with per-component builds. Then we also enable `-hide-all-packages`, so the dependency will not be available if it is not explicitly listed as a dependency. You could also imagine a future where the Setup.hs script found the test files and compiled a single executable which would run all the tests, rather than invoking runghc on each one individually. Fixes haskell#8356 * hurd: Enable using $ORIGIN in RPATH GNU/Hurd fully supports RPATH and the $ORIGIN development, and we indeed want to use it for relocatable installations shipped in Debian GNU/Hurd. * Fix the platform string for GNU/Hurd Since version 9.4.7-1, ghc fails to build on the GNU/Hurd port of Debian, see https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=hurd-i386&ver=9.4.7-1&stamp=1697717885&raw=0 Error, rule finished running but did not produce file: _build/stage0/lib/i386-gnu-ghc-9.4.6/ghc-boot-th-9.4.7/libHSghc-boot-th-9.4.7.a and indeed, what did get produce was rather _build/stage0/lib/i386-hurd-ghc-9.4.6/ghc-boot-th-9.4.7/libHSghc-boot-th-9.4.7.a (i386-hurd instead of i386-gnu). This is due to confusion between hurd and gnu in various places. Apparently previous versions of ghc were using gnu for the GNU/Hurd port, and thus putting libraries etc. in i386-gnu. So we have to follow the existing practice. * Fix configuation of ldProgram Standard GNU `ld` ues `--relocatable` while `ld.gold` uses a `-relocatable` flag (with a single `-`). Code will now detect both versions. * Chain configuration of ldProgram `ldProgram` gets configured in two places, a seemingly default and a GHC specific version. The later needs to be updated so that it first calls the default configuration and then the new GHC version. * Use linker capability detection to improve linker use The function `comperSupportsGhciLibs` has been renamed to `linkerSupportsGhciLibs` because its about the linker not the compiler. The function `comperSupportsGhciLibs` was using the compiler version as a proxy for whether the linker supports relocatable objects. Now support for relocatable objects is detected by running the linker. * add `merge+no rebase` and a few typos while reviewing * Add support for 64-bit SPARC as a separate architecture Previously, sparc64 was defined as an alias for the 32-bit SPARC architecture which was true while SPARC mainland was mostly 32 bits. More recently, 64-bit SPARC has become a port of its own, so it needs to be treated as a separate architecture. * Remove debug-conflict-sets flag from solver package Fixes haskell#8937. The debug-conflict-sets build flag probably hasn't been used for a long time, and it isn't currently tested. This commit removes the flag, converts the ConflictSet type back to a newtype, and removes an unnecessary instance. * Finish improvements to the CI configuration for documentation changes (haskell#9460) * Add bootstrap postjob to CI config Add a new job to the bootstrap.yml GitHub action config. This job succeeds if, and only if, all the other bootstrap jobs succeed. * Do not run bootstrap CI jobs for documentation changes The approach was already introduced in haskell#9355 for the validate jobs. This commit introduces the same change also for the bootstrap jobs. * Also ignore CONTRIBUTING.md and README.md in CI We do not run the entire CI suite for documentation changes. Previously, only changes which were restricted to the 'docs/' subdirectory were considered to be documentation changes. With this commit we also recognize changes to README.md and CONTRIBUTING.md as documentation changes. * Document improved CI for documentation in CONTRIBUTING.md The CONTRIBUTING.md file now mentions that documentation changes do not waste expensive CI resources. * Recognize all README.md in subdirs as documentation Expensive CI jobs should not run on changes which affect only README.md files. * formatting: Add style-commit makefile target This target allows you to format a range of commits, for example: ``` make style-commit COMMIT=HEAD~1 > Last commit is formatted make style-commit COMMIT=abcde > Commits between HEAD and abcde are formatted ``` * Fix assertion failure when combining build-tool-depends and --enable-documentation The `setDocumentation` function was modifying the elaborated package after the hash was computed.

Closes: haskell#9375 * Also revert in GHC.hs --------- Co-authored-by: Hamish Mackenzie <Hamish.K.Mackenzie@gmail.com> Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> * Use the newer haskell-actions organisation * Restructure Cabal documentation top-level parts The goal is for users to easier find pages for typical problems through search engines and page navigation. - The top-level layout is based on the popular documentation structure by https://documentation.divio.com/ to give a clear structure to users and future documentation contributors: * Guides: Present a solution to a single, atomic, typical user problem. * Reference: Describe user API (CLI fields, syntax etc) with technical rigour and completeness. * Explanation: Discuss background information, scope, design decisions etc. - Move existing documentation roughly into these categories with minimal editing as the basis for further editing. - Rename guide titles to mention how-to for improving SEO. - Rename some files to improve SEO since that name becomes part of the URL (often called slug). Important page keywords should appear in the slug as well to make pages rank higher in search engines. * Rename master_doc to root_doc (changed in version 4.0 of Sphynx) * Add instance Ord for Field, FieldLine, SectionArg and Name * Do not run CI for documentation changes The github workflows are not run if the changes are completely contained within the doc/ subdirectory.

Supersedes haskell#9398 * Require version 3,11 of Cabal to support --semaphore flag Fixes haskell#9197 * Add dependencies used by `PackageTests` to exe:cabal-tests The runner allows the tests to use extra dependencies and the custom Prelude from 'cabal-testsuite'. However, if the tests use a dependency, say 'directory', and there are two packages with the same unit id available in the store, the test fails since it doesn't know which one to pick. By including an extra dependency to directory, we force the test runner to use a specific version directory, fixing the test failure. * Use Paths_cabal_install for cabal-install version number (haskell#9421) * Use PackageInfo for cabal-install version number * Use Paths_cabal_install instead * Adjust documentation --------- Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> * Document --profiling-detail in setup-commands. Fixes haskell#9182 * Add test requirement to PR template Adding test becomes a checkmark instead of “bonus points”. * A 'cabal path' command. (haskell#8879) * Add a 'cabal path' command. * Formatting fix. * Another formatting fix. * Categorise "cabal path" as global command. * Allow individual paths to be printed. * Less duplication. * Add config-file to "cabal path". * Use sum type instead of strings. * cabal path: support --installdir. * Add documentation. * Better text. * Formatting. * Add some tests. * Improve tests. * Add changelog entry. * Mention "cabal path" in directory documentation. --------- Co-authored-by: Artem Pelenitsyn <a.pelenitsyn@gmail.com> * Reimplement `cabal check` (haskell#8427) * Fix Semigroup target instance When two target names are the same, `mappend`ing them should not error but just pick the first name. * Add `desugarBuildToolSimple` * Reimplement cabal check * Reorder test output * Fix autogen modules tests .cabal files * Add a number of tests * Add test for haskell#7423 i.e. Do not warn on -O2 if under off-by-default package configuration flag conditional. * Add a regression for: * Add another -WErrr test This is to make sure we do *not* report it if it is under a user, off-by-default flag. * Add test for non manual user flags. * Add “absolute path in extra-lib-dirs” test * Add if/else test * Add “dircheck on abspath” check * Add Package version internal test * Add PackageVersionsStraddle test * Add changelog for haskell#8427 * Integrate various reviews * Integrate Artem’s review (review) Clarify `combineNames` documentation By explaining the way it operates (working if the two names are equal or one is empty) and renaming the function from `combineName` to `combineNames`. (review) Use guards instead of if/then/else (review) Match inside argument list (review) Replace “white” with “allow” (review) Fix typo in comment (review) Fix typo in Check module documentation (review) Harmonise indentation for `data` decls First field goes in a new line than the data constructor, so we have more space. (review) Rename `Prim` module to `Types` (review) Add checkPackageFilesGPD `checkPackageFiles` — which works on PD — was used to perform IO. We introduce a function that does the same thing but works on GPD (which is more principled). `checkPackageFiles` cannot just be removed, since it is part of the interface of Distribution.PackageDescription.Check. Deprecation can be planned once “new check” is up and running. * Integrate Andreas’ review (review) Add named section to missing upper bound check “miss upper bound” checks will now list target type and name (“On executable 'myexe', these packages miss upper bounds”) for easier fixing by the user. (review) remove `cabal gen-bounds` suggestion Reasonable as `cabal gen-bounds` is stricter than `cabal check`, see haskell#8427 (comment) Once `gen-bounds` behaves in line with `check` we can readd the suggestion. (review) Do not warn on shared bounds When a target which depends on an internal library shares some dependencies with the latter, do not warn on upper bounds. An example is clearer library build-depends: text < 5 ⁝ build-depends: myPackage, ← no warning, internal text, ← no warning, shared bound monadacme ← warning! * Integrate Artem’s review /II (review) Split Check.hs Check.hs has been split in multiple file, each une sub 1000 lines: Check 857 lines Check.Common 147 lines Check.Conditional 204 lines Check.Monad 352 lines Check.Paths 387 lines Check.Target 765 lines Check.Warning 865 lines Migration guide: - Check GPD/PD checks plus work-tree checks. - Check.Common common types and functions that are *not* part of monadic checking setup. - Check.Conditional checks on CondTree and related matter (variables, duplicate modules). - Check.Monad Backbone of the checks, monadic inter- face and related functions. - Check.Paths Checks on files, directories, globs. - Check.Target Checks on realised targets (libraries, executables, benchmarks, testsuites). - Check.Warning Datatypes and strings for warnings and severities. (review) remove useless section header (review) Fix typo (review) Add warnings documentation (list) For each warning, we document constructor/brief description in the manual. This might not be much useful as not but it will come handy when introducing `--ignore=WARN` and similar flags. * (review Andreas) Clarify CheckExplanation comment Whoever modifies `CheckExplanation` data constructors needs to be aware that the documentation in doc/cabal-commands.rst has to be updated too. * Move internal Check modules to `other-modules` No need to expose Distribution.PackageDescription.Check.* to the world. API for checking, for cabal-install and other tools, should be in Distribution.PackageDescription.Check. * Make fourmolu happy Cabal codebase has now a formatter/style standard (see haskell#8950). “Ravioli ravioli, give me the formuoli” * Do not check for OptO in scripts See haskell#8963 for reason and clarification requests. * Remove useless PackageId parameter It is now in the Reader part of CheckM monad. * Do not check PVP on internal targets Internal: testsuite, benchmark. See haskell#8361. * Make hlint happy * Fix haskell#9122 When checking internal version ranges, we need to make sure we are not mistaking a libraries with the same name but from different packages. See haskell#9132. * Fix grammar neither…nor, completing what done in haskell#9162 * Integrate Brandon’s review: grammar * Remove unnecessary `-fvia-C` check Brandon’s review/II. --------- Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com> * ci: Enable windows tests for 9.6.3 There were two failing tests: 1. CCompilerOverride, was attempting to use gcc.exe rather than clang.exe without also overriding the C options which led to incorrect options being passed to gcc.exe. The fix is to override to clang.exe on ghc-9.4 or newer. 2. ForeignLibs exposes a bug in GHC (https://gitlab.haskell.org/ghc/ghc/-/issues/24185) and hence is skipped for GHCs newer than 9.4 where it was first introduced. Towards fixing haskell#8451, we just need to fix the shared library issue now. * testsuite: Be explicit about runtime test dependencies Issue haskell#8356 reports occasional errors from running the testsuite about multiple package versions available. This stems from the invokation of `runghc` not being explicit about all dependencies of the testsuite. The solution is provide a component in the cabal file which is explicit about which packages the tests can depend on. This component has a build-depends section which lists all the dependencies that the tests require. It would be better if this component was a library component but we can't do this with a Custom setup because of limitations to do with per-component builds. Then we also enable `-hide-all-packages`, so the dependency will not be available if it is not explicitly listed as a dependency. You could also imagine a future where the Setup.hs script found the test files and compiled a single executable which would run all the tests, rather than invoking runghc on each one individually. Fixes haskell#8356 * hurd: Enable using $ORIGIN in RPATH GNU/Hurd fully supports RPATH and the $ORIGIN development, and we indeed want to use it for relocatable installations shipped in Debian GNU/Hurd. * Fix the platform string for GNU/Hurd Since version 9.4.7-1, ghc fails to build on the GNU/Hurd port of Debian, see https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=hurd-i386&ver=9.4.7-1&stamp=1697717885&raw=0 Error, rule finished running but did not produce file: _build/stage0/lib/i386-gnu-ghc-9.4.6/ghc-boot-th-9.4.7/libHSghc-boot-th-9.4.7.a and indeed, what did get produce was rather _build/stage0/lib/i386-hurd-ghc-9.4.6/ghc-boot-th-9.4.7/libHSghc-boot-th-9.4.7.a (i386-hurd instead of i386-gnu). This is due to confusion between hurd and gnu in various places. Apparently previous versions of ghc were using gnu for the GNU/Hurd port, and thus putting libraries etc. in i386-gnu. So we have to follow the existing practice. * Fix configuation of ldProgram Standard GNU `ld` ues `--relocatable` while `ld.gold` uses a `-relocatable` flag (with a single `-`). Code will now detect both versions. * Chain configuration of ldProgram `ldProgram` gets configured in two places, a seemingly default and a GHC specific version. The later needs to be updated so that it first calls the default configuration and then the new GHC version. * Use linker capability detection to improve linker use The function `comperSupportsGhciLibs` has been renamed to `linkerSupportsGhciLibs` because its about the linker not the compiler. The function `comperSupportsGhciLibs` was using the compiler version as a proxy for whether the linker supports relocatable objects. Now support for relocatable objects is detected by running the linker. * add `merge+no rebase` and a few typos while reviewing * Add support for 64-bit SPARC as a separate architecture Previously, sparc64 was defined as an alias for the 32-bit SPARC architecture which was true while SPARC mainland was mostly 32 bits. More recently, 64-bit SPARC has become a port of its own, so it needs to be treated as a separate architecture. * Remove debug-conflict-sets flag from solver package Fixes haskell#8937. The debug-conflict-sets build flag probably hasn't been used for a long time, and it isn't currently tested. This commit removes the flag, converts the ConflictSet type back to a newtype, and removes an unnecessary instance. * Finish improvements to the CI configuration for documentation changes (haskell#9460) * Add bootstrap postjob to CI config Add a new job to the bootstrap.yml GitHub action config. This job succeeds if, and only if, all the other bootstrap jobs succeed. * Do not run bootstrap CI jobs for documentation changes The approach was already introduced in haskell#9355 for the validate jobs. This commit introduces the same change also for the bootstrap jobs. * Also ignore CONTRIBUTING.md and README.md in CI We do not run the entire CI suite for documentation changes. Previously, only changes which were restricted to the 'docs/' subdirectory were considered to be documentation changes. With this commit we also recognize changes to README.md and CONTRIBUTING.md as documentation changes. * Document improved CI for documentation in CONTRIBUTING.md The CONTRIBUTING.md file now mentions that documentation changes do not waste expensive CI resources. * Recognize all README.md in subdirs as documentation Expensive CI jobs should not run on changes which affect only README.md files. * formatting: Add style-commit makefile target This target allows you to format a range of commits, for example: ``` make style-commit COMMIT=HEAD~1 > Last commit is formatted make style-commit COMMIT=abcde > Commits between HEAD and abcde are formatted ``` * Fix assertion failure when combining build-tool-depends and --enable-documentation The `setDocumentation` function was modifying the elaborated package after the hash was computed. This led to the assertion failing as the computed hash was different to what was computed in the initial install plan. Therefore in order to fix this we either needed to: 1. Set elabBuildHaddocks = False at the point where the hash is initially computed. 2. Verify that elabBuildHaddocks = True will not lead to unexpected results. The latter has been implemented. The elabBuildHaddocks option is only consulted in `hasValidHaddockTargets`, at which point documentation building the executable component is disabled because elabHaddockExecutables is False. In the added test we ensure this by checking that we didn't build documentation for the executable which is built because of build-tool-depends. Fixes haskell#6006 haskell#8313 * testsuite: Improve error message in findDependencyInStore * Only move code to Simple/GHC/Build* * CPP mingw32_HOST_OS for more imports * cabal-install-solver: fix pkgconf 1.9 --modversion regression Check that the numbers of *versions* output is equal to the number of pkgconf's fixes haskell#8923 The pkgconf behavior was reverted upstream in 2.0 (this should cover the case too of checking that equal pkgList lines are output also) * External commands: Add tests for haskell#9402 haskell#9403 haskell#9404 This adds 4 tests which test the new external commands feature: * ExternalCommand - Tests the expected usage of external command invoked via cabal-install * ExternalCommandSetup - Tests that the ./Setup interface does not support external commands (haskell#9403) * ExternalCommandEnv - Tests that environment variables are set and preserved appropiately (haskell#9402) * ExternalCommandHelp - Test that `cabal help <cmd>` is interpreted appropiately (haskell#9404) * Finish off the external commands feature * Remove 'CommandDelegate' in favour of abstracting the fallback in 'commandsRun', there is a new variant 'commdandRunWithFallback' which takes a continuation - This restores the modularity between the `Cabal` library and `cabal-install` as now `Cabal` doesn't need to know anything about the external command interface. - Fixes haskell#9403 * Set the $CABAL environment variable to the current executable path - This allows external commands to be implemented by calling $CABAL, which is strongly preferred to linking against the Cabal library as there is no easy way to guantee your tool and `cabal-install` link against the same `Cabal` library. - Fixes haskell#9402 * Pass the name of the argument - This allows external commands to be implemented as symlinks to an executable, and multiple commands can be interpreted by the same executable. - Fixes haskell#9405 * `cabal help <cmd>` is interpreted as `cabal-<cmd> --help` for external commands. - This allows the `help` command to also work for external commands and hence they are better integrated into cabal-install. - Fixes haskell#9404 The tests are updated to test all these additions. These features bring the external command interface up to par with the cargo external command interface. * Use Base16 hash for script path. Issue haskell#9334 shows that `%` characters on Windows result in invalid paths, also `/` characters on Linux create invalid paths. This changes from using base64 to using base16 with the same length we use for unit-ids. * Migrate to haskell-actions/setup As of 2023-09-09, haskell/action/setup is no longer maintained. The comment # latest is mandatory for cabal-testsuite, see haskell#8133 is removed; as the validate job was already fixing a version of cabal-install. * testsuite: Introduce Cabal-tests library for common testsuite functions I noticed that Distribution.Utils.TempTestDir was only used in the testsuite but defined in the Cabal library. Rather than expose this in the public interface of the `Cabal` library, it is cleaner to refactor it into a separate library (`Cabal-tests`) which can be used by any testsuite component. Also, in future it gives a clearer place to put utility functions which need to be shared across the testsuite but not exposed in Cabal. Cabal-tests can also freely add dependencies (such as exceptions) which we might want to avoid adding to the Cabal library. Fixes haskell#9453 * GHC 9.8 compat: pacify -Wx-partial * GHC 9.8 compat: update hashes of data structures as computed by Structured It seems, GHC 9.8 changed something in the code generation for data types.
