[Git][ghc/ghc][master] wasm: add /assets endpoint to serve user-specified assets
by Marge Bot (＠marge-bot) 26 Feb '26

26 Feb '26

Marge Bot pushed to branch master at Glasgow Haskell Compiler / GHC Commits: c951fef1 by Cheng Shao at 2026-02-25T20:58:28+00:00 wasm: add /assets endpoint to serve user-specified assets This patch adds an `/assets` endpoint to the wasm dyld http server, so that users can also fetch assets from the same host with sensible default MIME types, without needing a separate http server for assets that also introduces CORS headaches: - A `-fghci-browser-assets-dir` driver flag is added to specify the assets root directory (defaults to `$PWD`) - The dyld http server fetches `mime-db` on demand and uses it as source of truth for mime types.

[Git][ghc/ghc][wip/fix-26953] 7 commits: Add optional `SrcLoc` to `StackAnnotation` class

We update builtin stack annotations such as `StringAnnotation` and `ShowAnnotation` to also capture the `SrcLoc` of the current `CallStack` to improve backtraces by default (if stack annotations are used).

So we want to avoid other modules depending on it as far as possible. On Windows, the IO manager depends on the RTSFlags type, which transtively depends on MonadFix. We refactor things to avoid this dependency, which would have caused a regression.

However, while the `GHC.Internal.Data.Bool` import was conditional and partial, the `GHC.Internal.Base` import is unconditional and total. As a result, the import list is not tuned to import only the necessary bits anymore, and furthermore GHC emits a lot of warnings about redundant imports. This commit makes the `GHC.Internal.Base` import conditional and partial in the same way that the `GHC.Internal.Data.Bool` import was. - - - - - 31a38ea0 by Recursion Ninja at 2026-02-26T11:34:35-05:00 Decoupling 'L.H.S' from 'GHC.Types.SourceText'. * Migrated 'IntegralLit' to 'L.H.S.Lit'. * Migrated 'FractionalLit' to 'L.H.S.Lit'. * Migrated 'StringLiteral' to 'L.H.S.Lit'. * Added TTG extension points to the types above. * Added nice export list to 'GHC.Hs.Lit'. * Added 'rnOverLitVal' and 'tcOverLitVal' functions to 'GHC.Hs.Lit'. * Moved [Notes] about 'SourceText' from 'L.H.S.*' to 'GHC.*'. * Removed all references to 'SourceText' from 'L.H.S'.

ExplicitLevelImports' change specification, however, does not do such an exemption. Thus we want to introduce such a check, just like we have for values. ExplicitLevelImports does not, however, talk about local names - from its perspective, we could theoretically keep treating locally introduced types specially - e.g. an ill-staged used in a quote would only emit a warning, not an error. To allow for a potential future migration away from such wrinkles as the staging check in notFound (see Note [Out of scope might be a staging error]) we consistently do the strict staging check that we also do for value if ExplicitLevelImports is on.

Although that bug is closed, it strongly implied that this special-case variable that only affected a single test was expected to be removed at some point. I also looked at 3415bcaa0b1903b5e12dfaadb5b774718e406eab---where it was added---whose commit message suggested that it would have been desirable to remove it, but that there were special circumstances that meant it had to remain (though it doesn't elucidate what those special circumstances are). However, the special circumstances were mentioned as if the test was in a different location than is currently is, so I decided to try changing the test to use the standard `extra_files` mechanism, which works in local testing. This also seems like a reasonable time to remove the script that was originally used in the transition, since it doesn't really serve a purpose anymore. - - - - - 0020e38a by Matthew Pickering at 2026-02-09T17:29:14-05:00 determinism: Use a stable sort in WithHsDocIdentifiers binary instance `WithHsDocIdentifiers` is defined as ``` 71 data WithHsDocIdentifiers a pass = WithHsDocIdentifiers 72 { hsDocString :: !a 73 , hsDocIdentifiers :: ![Located (IdP pass)] 74 } ``` This list of names is populated from `rnHsDocIdentifiers`, which calls `lookupGRE`, which calls `lookupOccEnv_AllNameSpaces`, which calls `nonDetEltsUFM` and returns the results in an order depending on uniques.

See `Note [Grand plan for static forms]` in GHC.Iface.Tidy.StaticPtrTable The main changes are: * There is a new, simple rule for (static e), namely that the free term variables of `e` must be bound at top level. The check is done in the `HsStatic` case of `GHC.Rename.Expr.rnExpr` * That in turn substantially simplifies the info that the typechecker carries around in its type environment. Hooray. * The desugarer emits static bindings to top level directly; see the `HsStatic` case of `dsExpr`. * There is no longer any special static-related magic in the FloatOut pass. And the main Simplifier pipeline no longer needs a special case to run FloatOut even with -O0. Hooray. All this forced an unexpected change to the pattern match checker. It recursively invokes the main Hs desugarer when it wants to take a look at a term to spot some special cases (notably constructor applications). We don't want to emit any nested (static e) bindings to top level a second time! Yikes. That forced a modest refactor in GHC.HsToCore.Pmc: * The `dsl_nablas` field of `DsLclEnv` now has a `NoPmc` case, which says "I'm desugaring just for pattern-match checking purposes". * When that flag is set we don't emit static binds. That in turn forces a cascade of refactoring, but the net effect is an improvement; less risk of duplicated (even exponential?) work.

Fixes #26876 - - - - - 17839248 by Teo Camarasu at 2026-02-24T08:36:03-05:00 ghc-internal: avoid depending on GHC.Internal.Control.Monad.Fix This module contains the definition of MonadFix, since we want an instance for IO, that instance requires a lot of machinery and we want to avoid an orphan instance, this will naturally be quite high up in the dependency graph. So we want to avoid other modules depending on it as far as possible. On Windows, the IO manager depends on the RTSFlags type, which transtively depends on MonadFix. We refactor things to avoid this dependency, which would have caused a regression. Resolves #26875 Metric Decrease: T12227 - - - - - fa88d09a by Wolfgang Jeltsch at 2026-02-24T08:36:47-05:00 Refine the imports of `System.IO.OS` Commit 68bd08055594b8cbf6148a72d108786deb6c12a1 replaced the `GHC.Internal.Data.Bool` import by a `GHC.Internal.Base` import. However, while the `GHC.Internal.Data.Bool` import was conditional and partial, the `GHC.Internal.Base` import is unconditional and total. As a result, the import list is not tuned to import only the necessary bits anymore, and furthermore GHC emits a lot of warnings about redundant imports. This commit makes the `GHC.Internal.Base` import conditional and partial in the same way that the `GHC.Internal.Data.Bool` import was. - - - - - e0fe781d by Vladislav Zavialov at 2026-02-26T01:28:30+03:00 Check for negative type literals in the type checker (#26861) GHC disallows negative type literals (e.g., -1), as tested by T8306 and T8412. This check is currently performed in the renamer: rnHsTyLit tyLit@(HsNumTy x i) = do when (i < 0) $ addErr $ TcRnNegativeNumTypeLiteral tyLit However, this check can be bypassed using RequiredTypeArguments (see the new test case T26861). Prior to this patch, such programs caused the compiler to hang instead of reporting a proper error. This patch addresses the issue by adding an equivalent check in the type checker, namely in tcHsType. The diff is deliberately minimal to facilitate backporting. A more comprehensive rework of HsTyLit is planned for a separate commit. - - - - - 13228aaf by Vladislav Zavialov at 2026-02-26T15:42:21+03:00 Drop HsTyLit in favor of HsLit (#26862, #25121) This patch is a small step towards unification of HsExpr and HsType, taking care of literals (HsLit) and type literals (HsTyLit). Additionally, it improves error messages for unsupported type literals, such as unboxed or fractional literals (test cases: T26862, T26862_th). Changes to the AST: * Use HsLit where HsTyLit was previously used * Use HsChar where HsCharTy was previously used * Use HsString where HsStrTy was previously used * Use HsNatural (NEW) where HsNumTy was previously used * Use HsDouble (NEW) to represent unsupported fractional type literals Changes to logic: * Parse unboxed and fractional type literals (to be rejected later) * Drop the check for negative literals in the renamer (rnHsTyLit) in favor of checking in the type checker (tc_hs_lit_ty) * Check for invalid type literals in TH (repTyLit) and report unrepresentable literals with ThUnsupportedTyLit * Allow negative type literals in TH (numTyLit). This is fine as these will be taken care of at splice time (test case: T8306_th) - - - - - 399 changed files: - .gitlab-ci.yml - .gitlab/ci.sh - + .gitlab/generate-ci/cabal.project - compiler/GHC/Builtin/Names.hs -
