This PR introduces a way to use GHC options that are not exposed by the `damlc` driver, by passing any number of `--ghc-option CUSTOM_OPTION` on the command line. The code uses the GHC function which parses options inside files, so prohibiting a few options that we would not want to expose (package db, output file, etc). All warnings that GHC emits during flag processing are presented to the user. If an option contradicts a DAML compiler setting, the compilation will be aborted with a GHC exception (calls makeDynFlagsConsistent internally). * HOTFIX damlc: small clean-up --- src/Development/IDE/UtilGHC.hs | 25 +++++++++++++++++++++++-- 1 file changed, 23 insertions(+), 2 deletions(-) diff --git a/src/Development/IDE/UtilGHC.hs b/src/Development/IDE/UtilGHC.hs index 7ff6407d3c..14ac457d3b 100644 --- a/src/Development/IDE/UtilGHC.hs +++ b/src/Development/IDE/UtilGHC.hs @@ -14,6 +14,8 @@ module Development.IDE.UtilGHC where import "ghc-lib-parser" Config +import qualified "ghc-lib-parser" CmdLineParser as Cmd (warnMsg) +import "ghc-lib-parser" DynFlags (parseDynamicFilePragma) import "ghc-lib-parser" Fingerprint import "ghc-lib" GHC hiding (convertLit) import "ghc-lib-parser" GHC.LanguageExtensions.Type @@ -21,11 +23,13 @@ import "ghc-lib-parser" GhcMonad import "ghc-lib" GhcPlugins as GHC hiding (PackageState, fst3, (<>)) import "ghc-lib" HscMain import qualified "ghc-lib-parser" Packages +import "ghc-lib-parser" Panic (throwGhcExceptionIO) import "ghc-lib-parser" Platform import qualified "ghc-lib-parser" StringBuffer as SB import qualified "ghc-lib-parser" EnumSet import Control.DeepSeq +import Control.Monad import Data.IORef import Data.List import qualified Data.Text as T @@ -185,9 +189,26 @@ instance NFData PackageState where -- * Installs a custom log action; -- * Sets up the package databases; -- * Sets the import paths to the given list of 'FilePath'. -setupDamlGHC :: GhcMonad m => [FilePath] -> Maybe String -> PackageState -> m () -setupDamlGHC importPaths mbPackageName packageState = do +-- * if present, parses and applies custom options for GHC +-- (may fail if the custom options are inconsistent with std DAML ones) +setupDamlGHC :: GhcMonad m => [FilePath] -> Maybe String -> PackageState -> [String] -> m () +setupDamlGHC importPaths mbPackageName packageState [] = modifyDynFlags $ adjustDynFlags importPaths packageState mbPackageName +-- if custom options are given, add them after the standard DAML flag setup +setupDamlGHC importPaths mbPackageName packageState customOpts = do + setupDamlGHC importPaths mbPackageName packageState [] + damlDFlags <- getSessionDynFlags + (dflags', leftover, warns) <- parseDynamicFilePragma damlDFlags $ map noLoc customOpts + + let leftoverError = CmdLineError $ + (unlines .

This PR merges them into one to make this less confusing. 2. buildDar called runAction a bunch of times directly and via other functions. This PR switches it to use a single call to runAction. 3. The logic for turning a Maybe into an `ExceptT [FileDiagnostic]` was duplicated in various places. This PR factor out the logic into a single function. There is certainly more cleanup to be done (e.g., I don’t think ExceptT buys us anything here, that module should probably die completely with the logic being moved to other modules, …) but I’d like to do it incrementally. --- src/Development/IDE/State/Rules.hs | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-) diff --git a/src/Development/IDE/State/Rules.hs b/src/Development/IDE/State/Rules.hs index 8afb64fef3..3afe0e3421 100644 --- a/src/Development/IDE/State/Rules.hs +++ b/src/Development/IDE/State/Rules.hs @@ -19,7 +19,6 @@ module Development.IDE.State.Rules( getAtPoint, getDefinition, getDependencies, -

DAML is a smart contract language targeting distributed-ledger runtimes, based on [GHC](https://www.haskell.org/ghc/) with custom language extensions. The DAML programming langauge has [an IDE](https://webide.daml.com/), and work was done to separate off a reusable Haskell-only IDE (what is now `ghcide`) which the [DAML IDE then builds upon](https://github.com/digital-asset/daml/tree/master/compiler/damlc). Since that time, there have been various [non-Digital Asset contributors](https://github.com/digital-asset/ghcide/graphs/contributors), in addition to continued investment by Digital Asset. + +The Haskell community [has](https://github.com/DanielG/ghc-mod) [various](https://github.com/chrisdone/intero) [IDE](https://github.com/rikvdkleij/intellij-haskell) [choices](http://leksah.org/), but the one that has been gathering momentum is [`haskell-ide-engine`](https://github.com/haskell/haskell-ide-engine#readme). Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. While `ghcide` is not a part of `haskell-ide-engine`, we feel it _could_ form the core of a future version - but such decisions are up to the `haskell-ide-engine` contributors. + +The best summary of the architecture of `ghcide` is available [this talk](https://www.youtube.com/watch?v=cijsaeWNf2E&list=PLxxF72uPfQVRdAsvj7THoys-nVj-oc4Ss) ([slides](https://ndmitchell.com/downloads/slides-making_a_haskell_ide-07_sep_2019.pdf)), given at [MuniHac 2019](https://munihac.de/2019.html). However, since that talk the project has renamed from `hie-core` to `ghcide`, and the repo has moved to [this location](https://github.com/digital-asset/ghcide/).

As it turns out the first, most obvious approach, does not work: this is documented in the next commit. A second approach was found that does work, and appears in the commit after the next. This test is failing until the second approach is implemented. * Defer type errors (first approach: FAILED) The idea is to set the `-fdefer-type-errors` and `-fwarn-deferred-type-errors` flags, by setting options programatically inside the `Ghc` monad. Deferral of type errors was not observed with this approach. The (less obvious) approach used in the next commit seems to be more successful. * Defer type errors (second approach: SUCCESS) This approach modifies the `ParsedModule` which is passed to `GHC.typecheckedModule` by hie-core's `typecheckModule`. Type warning deferral is now observed at run time, and the tests pass. * TEST: Reinstate severity of type errors So far, type errors have been deferred and reported as warnings. The next step is to ensure that the deferred type errors are reported as errors rather than warnings, once again. This test fails until the implementation arrives in the next commit. * Upgrade severity of deferred Type Errors after typecheck ... and make the test pass again. * Hide helper functions in local scopes * Stop setting Opt_WarnDeferredTypeErrors ... and the tests still pass, thereby confirming @hsenag's hypothesis that this flag is not needed. * TEST: Check that typed holes are reported as errors * TEST: Downgrade severity of typed holes Error -> Warning This test fails, thereby falsifying the hypothesis that `Opt_DeferTypeErrors` implies `Opt_DeferTypedHoles`. * Defer typed holes ... and pass the failing test. * TEST: Reinstate severity of typed holes ... failing the test until the implementation catches up in the next commit. * Upgrade severity of deferred Typed Holes after typecheck ... and pass the test once again. * TEST: Degrade variable out of scope from Error to Warning ... test fails until next commit. * Defer out of scope variables ... passing the test which was changed in the last commit. * TEST: Reinstate severity of out of scope variables ... failing the test, and forcing the implementation to catch up. * Upgrade severity of deferred out of scope vars after typecheck ... passing the test once again. * Add explicit tests for deferrals * Add IdeOption for deferral switching * Improve documentation of optDefer * Add IdeDefer newtype --- src/Development/IDE/Core/Compile.hs | 37 ++++++++++++++++++++++++---- src/Development/IDE/Core/Rules.hs | 3 ++- src/Development/IDE/GHC/Warnings.hs | 8 +++--- src/Development/IDE/Types/Options.hs | 9 +++++++ test/exe/Main.hs | 37 ++++++++++++++++++++++++++++ 5 files changed, 84 insertions(+), 10 deletions(-) diff --git a/src/Development/IDE/Core/Compile.hs b/src/Development/IDE/Core/Compile.hs index 8a314eaeba..9b4d170d63 100644 --- a/src/Development/IDE/Core/Compile.hs +++ b/src/Development/IDE/Core/Compile.hs @@ -82,19 +82,22 @@ computePackageDeps env pkg = do -- | Typecheck a single module using the supplied dependencies and packages. typecheckModule - :: HscEnv + :: IdeDefer + -> HscEnv -> [TcModuleResult] -> ParsedModule -> IO ([FileDiagnostic], Maybe TcModuleResult) -typecheckModule packageState deps pm = +typecheckModule (IdeDefer defer) packageState deps pm = + let demoteIfDefer = if defer then demoteTypeErrorsToWarnings else id + in fmap (either (, Nothing) (second Just)) $ runGhcEnv packageState $ catchSrcErrors "typecheck" $ do setupEnv deps (warnings, tcm) <- withWarnings "typecheck" $ \tweak -> - GHC.typecheckModule pm{pm_mod_summary = tweak $ pm_mod_summary pm} + GHC.typecheckModule $ demoteIfDefer pm{pm_mod_summary = tweak $ pm_mod_summary pm} tcm2 <- mkTcModuleResult tcm - return (warnings, tcm2) + return (map unDefer warnings, tcm2) -- | Compile a single type-checked module to a 'CoreModule' value, or -- provide errors. @@ -126,8 +129,32 @@ compileModule packageState deps tmr = (cg_binds tidy) (mg_safe_haskell desugar) - return (warnings, core) + return (map snd warnings, core) + +demoteTypeErrorsToWarnings :: ParsedModule -> ParsedModule +demoteTypeErrorsToWarnings = + (update_pm_mod_summary . update_hspp_opts) demoteTEsToWarns where + + demoteTEsToWarns :: DynFlags -> DynFlags + demoteTEsToWarns = (`gopt_set` Opt_DeferTypeErrors) + .

The Haskell community [has](https://github.com/DanielG/ghc-mod) [various](https://github.com/chrisdone/intero) [IDE](https://github.com/rikvdkleij/intellij-haskell) [choices](http://leksah.org/), but the one that has been gathering momentum is [`haskell-ide-engine`](https://github.com/haskell/haskell-ide-engine#readme). Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. While `ghcide` is not a part of `haskell-ide-engine`, we feel it _could_ form the core of a future version - but such decisions are up to the `haskell-ide-engine` contributors.

Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. While `ghcide` is not a part of `haskell-ide-engine`, we feel it _could_ form the core of a future version - but such decisions are up to the `haskell-ide-engine` contributors.

DAML is a smart contract language targeting distributed-ledger runtimes, based on [GHC](https://www.haskell.org/ghc/) with custom language extensions. The DAML programming language has [an IDE](https://webide.daml.com/), and work was done to separate off a reusable Haskell-only IDE (what is now `ghcide`) which the [DAML IDE then builds upon](https://github.com/digital-asset/daml/tree/master/compiler/damlc). Since that time, there have been various [non-Digital Asset contributors](https://github.com/digital-asset/ghcide/graphs/contributors), in addition to continued investment by Digital Asset. All contributions require a [Contributor License Agreement](https://cla.digitalasset.com/digital-asset/ghcide) that states you license the code under the [Apache License](LICENSE).

If that happens, you need to either set `NIX_GHC_LIBDIR` (so `ghcide` can see it) or use a proper [Nix compatible wrapper](https://github.com/hercules-ci/ghcide-nix) over `ghcide`.

Nested spans were meant to be sorted in innermost-first order, with the first (innermost) one being used to get type information about the symbol at a given position. Because the comparison function considered any two non-nested spans to be EQ, the sort could incorrectly conclude (by transitivity) that two nested spans were equal, and thus leave them in incorrect relative order. This resulted in the innermost span sometimes not appearing at the front of the list of spans which enclose a given point, and hover reporting the type of a bigger expression in which the point appeared.

Information about spans includes a `Maybe Type` which is `Just` for data-level expressions and `Nothing` for type-level expressions. `AtPoint.atPoint` which is the oddly-named function responsible for constructing hover information, runs in the `Maybe` monad, and aborted at the first sight of a `Nothing`, thus producing no hover information for type-level spans. In the process of fixing this, I have refactored the function to + separate the construction of data-level and type-level hover info + make the components that make up the hover info (and their construction) more clear I can see plenty little improvements that could be made to the functionality of the code (and lots that could be made to its organization), but the most important fixes of the basic missing functionality are here.

This is done by looking at the parsed module. This PR fixes two things: 1. While we only use the parsed module for getting the context previously we got the parsed module out of the typechecked module. This means that if you have a module that parses but doesn’t typecheck, we will use the parsed module at the point where it last typechecked which is out of date and produces incorrect (or just no) contexts. 2. When we could not find a context, we defaulted to assuming we are in a value context. Especially in combination with 1 but also just in general, this is rather annoying. If we aren’t sure we should show the user everything we have and not filter out some completions. Filtering out completions interacts particularly badly with VSCode’s default behavior of accepting the first completion when you press return. --- src/Development/IDE/Plugin/Completions.hs | 22 +++++++++++-------- .../IDE/Plugin/Completions/Logic.hs | 21 +++++++++--------- test/exe/Main.hs | 21 ++++++++++++++++++ 3 files changed, 44 insertions(+), 20 deletions(-) diff --git a/src/Development/IDE/Plugin/Completions.hs b/src/Development/IDE/Plugin/Completions.hs index 32016777b5..d3a8a52305 100644 --- a/src/Development/IDE/Plugin/Completions.hs +++ b/src/Development/IDE/Plugin/Completions.hs @@ -2,6 +2,8 @@ module Development.IDE.Plugin.Completions(plugin) where +import Control.Applicative +import Data.Maybe import Language.Haskell.LSP.Messages import Language.Haskell.LSP.Types import qualified Language.Haskell.LSP.Core as LSP @@ -10,8 +12,6 @@ import Language.Haskell.LSP.Types.Capabilities import Development.Shake.Classes import Development.Shake import GHC.Generics -import Data.Maybe -import HscTypes import Development.IDE.Plugin import Development.IDE.Core.Service @@ -37,14 +37,14 @@ produceCompletions = packageState <- fmap (hscEnv . fst) <$> useWithStale GhcSession file case (tm, packageState) of (Just tm', Just packageState') -> do - cdata <- liftIO $ cacheDataProducer packageState' (hsc_dflags packageState') + cdata <- liftIO $ cacheDataProducer packageState' (tmrModule tm') parsedDeps - return ([], Just (cdata, tm')) + return ([], Just cdata) _ -> return ([], Nothing) -- | Produce completions info for a file -type instance RuleResult ProduceCompletions = (CachedCompletions, TcModuleResult) +type instance RuleResult ProduceCompletions = CachedCompletions data ProduceCompletions = ProduceCompletions deriving (Eq, Show, Typeable, Generic) @@ -67,17 +67,21 @@ getCompletionsLSP lsp ide fmap Right $ case (contents, uriToFilePath' uri) of (Just cnts, Just path) -> do let npath = toNormalizedFilePath path - (ideOpts, compls) <- runAction ide ((,) <$> getIdeOptions <*> useWithStale ProduceCompletions npath) + (ideOpts, compls) <- runAction ide $ do + opts <- getIdeOptions + compls <- useWithStale ProduceCompletions npath + pm <- useWithStale GetParsedModule npath + pure (opts, liftA2 (,) compls pm) case compls of - Just ((cci', tm'), mapping) -> do - let position' = fromCurrentPosition mapping position + Just ((cci', _), (pm, mapping)) -> do + let !position' = fromCurrentPosition mapping position pfix <- maybe (return Nothing) (flip VFS.getCompletionPrefix cnts) position' case (pfix, completionContext) of (Just (VFS.PosPrefixInfo _ "" _ _), Just CompletionContext { _triggerCharacter = Just "."}) -> return (Completions $ List []) (Just pfix', _) -> do let fakeClientCapabilities = ClientCapabilities Nothing Nothing Nothing Nothing - Completions .

This means the .hs-boot file was getting added into the HPT after the .hs file which led to confusing errors about variables being out of scope. The fix is to maintain a map from hs-boot to hs files and then add an edge for this case when calling `transitiveDependencies`. Also tidy up some code in setupEnv which I assume was attempting to fix this but in an incorrect manner. Add the -boot suffix when looking for hi-boot files. For some reason, the `hi` path is not set to the right thing for `hs-boot` files. I don't know why not perhaps it is ok to use an existing `.hi` file in place of an `hs-boot` file. More investigation needed. My experience is that GHC is quite bad a recompilation avoidance for hs-boot files anyway. For example: https://gitlab.haskell.org/ghc/ghc/issues/17434 Add the -boot suffix when writing interface files * Generate .hi and .hie files during type checking * Refactor GetModIface to not retain TypeChecked module in memory This improves memory performance on a cold cache. * Trailing whitespace * Turn debug log messages into diagnostics * Implement "hie" files for ghc-8.6.5 This means that the .hi files patch can also be used with 8.6.5 * Add tests for hover/definition on imported symbols * hlints * Generate .hie files when missing * Fix subtle bug in setDefaultHieDir * Simplify optimal project setup in README * Move interface loading diagnostics behind --test flag Reusing the --test flag for this seems harmless, I cannot justify introducing a new flag * Avoid expensive interface file generation for files of interest * avoid redundant arguments (thanks Moritz K) * qualify a DAML only comment * Skip module source when generating hie file thanks Moritz Kiefer for noting that we don't care for the generated .hie files to embed module sources * runGhcEnv <-> evalGhcEnv * Apply suggestions from code review Thanks Moritz Kiefer Co-Authored-By: Moritz Kiefer * Add suggested Show instance Co-Authored-By: Matthew Pickering * Use Control.Exception.Safe This is to avoid accidentally capturing asynchronous exceptions * Rename atomicFileUpdate * Fix a flaky test We have to be careful with module naming in tests to avoid interference of .hi files across tests * Undo formatting of D.IDE.GHC.Util * follow changes in master Co-authored-by: Matthew Pickering Co-authored-by: Moritz Kiefer --- README.md | 4 + exe/Main.hs | 1 + ghcide.cabal | 5 + src/Development/IDE/Core/Compile.hs | 219 +- src/Development/IDE/Core/RuleTypes.hs | 43 + src/Development/IDE/Core/Rules.hs | 231 ++- src/Development/IDE/GHC/Compat.hs | 108 +- src/Development/IDE/GHC/HieAst.hs | 1789 +++++++++++++++++ src/Development/IDE/GHC/Util.hs | 18 +- .../IDE/Import/DependencyInformation.hs | 37 +- src/Development/IDE/Import/FindImports.hs | 11 +- .../IDE/Plugin/Completions/Logic.hs | 6 +- src/Development/IDE/Spans/AtPoint.hs | 9 +- src/Development/IDE/Spans/Calculate.hs | 25 +- src/Development/IDE/Types/Diagnostics.hs | 17 +- src/Development/IDE/Types/Options.hs | 3 + test/data/Bar.hs | 3 + test/data/Foo.hs | 5 + test/data/GotoHover.hs | 7 + test/exe/Main.hs | 174 +- test/src/Development/IDE/Test.hs | 27 +- 21 files changed, 2519 insertions(+), 223 deletions(-) create mode 100644 src/Development/IDE/GHC/HieAst.hs create mode 100644 test/data/Bar.hs create mode 100644 test/data/Foo.hs diff --git a/README.md b/README.md index 1838309609..56561b95b1 100644 --- a/README.md +++ b/README.md @@ -64,6 +64,10 @@ The `ghcide` executable mostly relies on [`hie-bios`](https://github.com/mpicker If you can't get `ghcide` working outside the editor, see [this setup troubleshooting guide](docs/Setup.md).

The technical work is ongoing, with the likely model being that this project serves as the core, while plugins and integrations are kept in the [`haskell-language-server` project](https://github.com/haskell/haskell-language-server). + The code behind `ghcide` was originally developed by [Digital Asset](https://digitalasset.com/) as part of the [DAML programming language](https://github.com/digital-asset/daml). DAML is a smart contract language targeting distributed-ledger runtimes, based on [GHC](https://www.haskell.org/ghc/) with custom language extensions. The DAML programming language has [an IDE](https://webide.daml.com/), and work was done to separate off a reusable Haskell-only IDE (what is now `ghcide`) which the [DAML IDE then builds upon](https://github.com/digital-asset/daml/tree/master/compiler/damlc). Since that time, there have been various [non-Digital Asset contributors](https://github.com/digital-asset/ghcide/graphs/contributors), in addition to continued investment by Digital Asset. All contributions require a [Contributor License Agreement](https://cla.digitalasset.com/digital-asset/ghcide) that states you license the code under the [Apache License](LICENSE). -The Haskell community [has](https://github.com/DanielG/ghc-mod) [various](https://github.com/chrisdone/intero) [IDE](https://github.com/rikvdkleij/intellij-haskell) [choices](http://leksah.org/), but the one that has been gathering momentum is [`haskell-ide-engine`](https://github.com/haskell/haskell-ide-engine#readme). Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. While `ghcide` is not a part of `haskell-ide-engine`, we feel it _could_ form the core of a future version - but such decisions are up to the `haskell-ide-engine` contributors. +The Haskell community [has](https://github.com/DanielG/ghc-mod) [various](https://github.com/chrisdone/intero) [IDE](https://github.com/rikvdkleij/intellij-haskell) [choices](http://leksah.org/), but the one that had been gathering momentum is [`haskell-ide-engine`](https://github.com/haskell/haskell-ide-engine#readme). Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. The best summary of the architecture of `ghcide` is available [this talk](https://www.youtube.com/watch?v=cijsaeWNf2E&list=PLxxF72uPfQVRdAsvj7THoys-nVj-oc4Ss) ([slides](https://ndmitchell.com/downloads/slides-making_a_haskell_ide-07_sep_2019.pdf)), given at [MuniHac 2019](https://munihac.de/2019.html). However, since that talk the project has renamed from `hie-core` to `ghcide`, and the repo has moved to [this location](https://github.com/digital-asset/ghcide/). From 4f9c7561ee26edbc1ecb00c8ee7655d904f8b134 Mon Sep 17 00:00:00 2001 From: Pepe Iborra Date: Mon, 27 Apr 2020 10:05:39 +0100 Subject: [PATCH 450/703] Parse module headers (#511) * Create rule to get ModSummary without parsing entire source file * Load file source from disk if not available in memory * Fix build after cherry pick * Couple of fixes - extract getModSummaryFromImports and fix diagnostics - replace GetParsedModule by GetModSummary where possible There is only one usage of GetParsedModule left, and that is in GetSpanInfos for documentation. This the wrong approach, docs should be loaded from interface files and not from sources. TODO * Fix watched file tests Progress notifications are not being sent anymore * Compat with GHC 8.6 * Avoid parsing source files for completions and documentation Instead, embed haddocks in interface files * Allow CPP in module * Force things after parsing in order to release buffers * avoid holding on to stringbuffer unnecessarily * Skip unnecessary file contents read * Drop HscEnv requirement * Add comments on forcing things * Add comments on GHC_LIB restriction * Parse files of interest twice to capture Haddock errors If Opt_Haddock is not enabled we parse twice to capture Haddock parse errors * Parallelize two-pass parsing * Update src/Development/IDE/Core/Compile.hs Co-authored-by: Marcelo Lazaroni Co-authored-by: Moritz Kiefer --- .hlint.yaml | 1 + ghcide.cabal | 1 + src/Development/IDE/Core/Compile.hs | 63 ++++++++-- src/Development/IDE/Core/Preprocessor.hs | 14 ++- src/Development/IDE/Core/RuleTypes.hs | 11 +- src/Development/IDE/Core/Rules.hs | 138 +++++++++++++++------- src/Development/IDE/GHC/Compat.hs | 26 ++++ src/Development/IDE/GHC/Error.hs | 23 +++- src/Development/IDE/GHC/Orphans.hs | 9 +- src/Development/IDE/GHC/Util.hs | 8 +- src/Development/IDE/GHC/WithDynFlags.hs | 30 +++++ src/Development/IDE/Plugin/Completions.hs | 15 ++- src/Development/IDE/Spans/Calculate.hs | 16 +-- test/exe/Main.hs | 51 +++++--- 14 files changed, 316 insertions(+), 90 deletions(-) create mode 100644 src/Development/IDE/GHC/WithDynFlags.hs diff --git a/.hlint.yaml b/.hlint.yaml index f4a37585ba..a368cf1eb7 100644 --- a/.hlint.yaml +++ b/.hlint.yaml @@ -85,6 +85,7 @@ -

We remove the special case of the initial module from the dependency search. It is now treated uniformly like the rest of the modules. 2. rawDependencyInformation can now take a list of files and create dependency information for all of them. This isn't currently used but on my fork we have a rule which gets the dependency information for the whole project in order to create a module graph. It seemed simplest to upstream this part first, which is already a strict improvement to make the overal patch easier to review. * Make indentation not depend on identifier length Co-authored-by: Moritz Kiefer --- src/Development/IDE/Core/Rules.hs | 134 ++++++++++++++-------- src/Development/IDE/Import/FindImports.hs | 8 ++ 2 files changed, 94 insertions(+), 48 deletions(-) diff --git a/src/Development/IDE/Core/Rules.hs b/src/Development/IDE/Core/Rules.hs index 86999ceb20..5808380427 100644 --- a/src/Development/IDE/Core/Rules.hs +++ b/src/Development/IDE/Core/Rules.hs @@ -28,8 +28,8 @@ module Development.IDE.Core.Rules( import Fingerprint -import Data.Binary -import Data.Bifunctor (second) +import Data.Binary hiding (get, put) +import Data.Bifunctor (first, second) import Control.Monad.Extra import Control.Monad.Trans.Class import Control.Monad.Trans.Maybe @@ -46,13 +46,11 @@ import Development.IDE.Types.Location import Development.IDE.GHC.Compat hiding (parseModule, typecheckModule) import Development.IDE.GHC.Util import Development.IDE.GHC.WithDynFlags -import Data.Coerce import Data.Either.Extra import Data.Maybe import Data.Foldable import qualified Data.IntMap.Strict as IntMap import Data.IntMap.Strict (IntMap) -import qualified Data.IntSet as IntSet import Data.List import Data.Ord import qualified Data.Set as Set @@ -70,11 +68,13 @@ import GHC.Generics(Generic) import qualified Development.IDE.Spans.AtPoint as AtPoint import Development.IDE.Core.Service import Development.IDE.Core.Shake -import Development.Shake.Classes +import Development.Shake.Classes hiding (get, put) import Control.Monad.Trans.Except (runExceptT) import Data.ByteString (ByteString) import Control.Concurrent.Async (concurrently) +import Control.Monad.State + -- | This is useful for rules to convert rules that can only produce errors or -- a result into the more general IdeResult type that supports producing -- warnings while also producing a result. @@ -251,53 +251,91 @@ getLocatedImportsRule = Nothing -> pure (concat diags, Nothing) Just pkgImports -> pure (concat diags, Just (moduleImports, Set.fromList $ concat pkgImports)) +type RawDepM a = StateT (RawDependencyInformation, IntMap ArtifactsLocation) Action a + +execRawDepM :: Monad m => StateT (RawDependencyInformation, IntMap a1) m a2 -> m (RawDependencyInformation, IntMap a1) +execRawDepM act = + execStateT act + ( RawDependencyInformation IntMap.empty emptyPathIdMap IntMap.empty + , IntMap.empty + ) + -- | Given a target file path, construct the raw dependency results by following -- imports recursively. -rawDependencyInformation :: NormalizedFilePath -> Action RawDependencyInformation -rawDependencyInformation f = do -

The current behaviour is that each component is loaded lazily into the session. When a file from an unrecognised component is loaded, the cradle is consulted again to get a new set of options for the new component. This will cause all the currently loaded files to be reloaded into a new HscEnv which is shared by all the currently known components. The result of this is that functions such as go-to definition work between components if they have been loaded into the same session but you have to open at least one file from each component before it will work. Only minimal changes are needed to the internals to ghcide to make the file searching logic look in include directories for all currently loaded components. The main changes are in exe/Main.hs which has been heavily rewritten to avoid shake indirections. A global map is created which maps a filepath to the HscEnv which should be used to compile it. When a new component is created this map is completely refreshed so each path maps to a new Which paths belong to a componenent is determined by the targets listed by the cradle. Therefore it is important that each cradle also lists all the targets for the cradle. There are some other choices here as well which are less accurate such as mapping via include directories which is the aproach that I implemented in haskell-ide-engine. The commit has been tested so far with cabal and hadrian. Also deleted the .ghci file which was causing errors during testing and seemed broken anyway.

The technical work is ongoing, with the likely model being that this project serves as the core, while plugins and integrations are kept in the [`haskell-language-server` project](https://github.com/haskell/haskell-language-server). The code behind `ghcide` was originally developed by [Digital Asset](https://digitalasset.com/) as part of the [DAML programming language](https://github.com/digital-asset/daml). DAML is a smart contract language targeting distributed-ledger runtimes, based on [GHC](https://www.haskell.org/ghc/) with custom language extensions. The DAML programming language has [an IDE](https://webide.daml.com/), and work was done to separate off a reusable Haskell-only IDE (what is now `ghcide`) which the [DAML IDE then builds upon](https://github.com/digital-asset/daml/tree/master/compiler/damlc). Since that time, there have been various [non-Digital Asset contributors](https://github.com/digital-asset/ghcide/graphs/contributors), in addition to continued investment by Digital Asset.

ShakeSession and shakeEnqueue (#554) * ShakeSession and shakeRunGently Currently we start a new Shake session for every interaction with the Shake database, including type checking, hovers, code actions, completions, etc. Since only one Shake session can ever exist, we abort the active session if any in order to execute the new command in a responsive manner. This is suboptimal in many, many ways: - A hover in module M aborts the typechecking of module M, only to start over! - Read-only commands (hover, code action, completion) need to typecheck all the modules! (or rather, ask Shake to check that the typechecks are current) - There is no way to run non-interfering commands concurrently This is an experiment inspired by the 'ShakeQueue' of @mpickering, and the follow-up discussion in https://github.com/mpickering/ghcide/issues/7 We introduce the concept of the 'ShakeSession' as part of the IDE state. The 'ShakeSession' is initialized by a call to 'shakeRun', and survives until the next call to 'shakeRun'. It is important that the session is restarted as soon as the filesystem changes, to ensure that the database is current. The 'ShakeSession' enables a new command 'shakeRunGently', which appends work to the existing 'ShakeSession'. This command can be called in parallel without any restriction. * Simplify by assuming there is always a ShakeSession * Improved naming and docs * Define runActionSync on top of shakeEnqueue shakeRun is not correct as it never returns anymore * Drive progress reporting from newSession The previous approach reused the shakeProgress thread, which doesn't work anymore as ShakeSession keeps the ShakeDatabase open until the next edit * Deterministic progress messages in tests Dropping the 0.1s sleep to ensure that progress messages during tests are deterministic * Make kick explicit This is required for progress reporting to work, see notes in shakeRun As to whether this is the right thing to do: 1. Less magic, more explicit 2. There's only 2 places where kick is actually used * apply Neil's feedback * avoid a deadlock when the enqueued action throws * Simplify runAction + comments * use a Barrier for clarity A Barrier is a smaller abstraction than an MVar, and the next version of the extra package will come with a suitably small implementation: https://github.com/ndmitchell/extra/commit/98c2a83585d2ca0a9d961dd241c4a967ef87866a * Log timings for code actions, hovers and completions * Rename shakeRun to shakeRestart The action returned by shakeRun now blocks until another call to shakeRun is made, which is a change in behaviour,. but all the current uses of shakeRun ignore this action. Since the new behaviour is not useful, this change simplifies and updates the docs and name accordingly * delete runActionSync as it's just runAction * restart shake session on new component created * requeue pending actions on session restart * hlint * Bumped the delay from 5 to 6 * Add a test for the non-lsp command line * Update exe/Main.hs Co-authored-by: Moritz Kiefer --- exe/Main.hs | 25 ++- src/Development/IDE/Core/FileStore.hs | 5 +- src/Development/IDE/Core/OfInterest.hs | 11 +- src/Development/IDE/Core/Service.hs | 23 +-- src/Development/IDE/Core/Shake.hs | 205 +++++++++++++++------ src/Development/IDE/LSP/HoverDefinition.hs | 8 +- src/Development/IDE/Plugin/CodeAction.hs | 41 +++-- src/Development/IDE/Plugin/Completions.hs | 13 +- src/Development/IDE/Types/Options.hs | 6 +- test/exe/Main.hs | 19 +- 10 files changed, 240 insertions(+), 116 deletions(-) diff --git a/exe/Main.hs b/exe/Main.hs index e423f36236..0096a06714 100644 --- a/exe/Main.hs +++ b/exe/Main.hs @@ -58,7 +58,7 @@ import System.Time.Extra import HIE.Bios.Environment (addCmdOpts, makeDynFlagsAbsolute) import Paths_ghcide import Development.GitRev -import Development.Shake (Action, action) +import Development.Shake (Action) import qualified Data.HashSet as HashSet import qualified Data.HashMap.Strict as HM import qualified Data.Map.Strict as Map @@ -124,11 +124,11 @@ main = do let options = (defaultIdeOptions $ loadSessionShake dir) { optReportProgress = clientSupportsProgress caps , optShakeProfiling = argsShakeProfiling - , optTesting = argsTesting + , optTesting = IdeTesting argsTesting , optThreads = argsThreads } debouncer <- newAsyncDebouncer - initialise caps (mainRule >> pluginRules plugins >> action kick) + initialise caps (mainRule >> pluginRules plugins) getLspId event (logger minBound) debouncer options vfs else do -- GHC produces messages with UTF8 in them, so make sure the terminal doesn't error @@ -156,14 +156,14 @@ main = do putStrLn "\nStep 4/4: Type checking the files" setFilesOfInterest ide $ HashSet.fromList $ map toNormalizedFilePath' files - results <- runActionSync ide $ uses TypeCheck (map toNormalizedFilePath' files) + results <- runAction ide $ uses TypeCheck (map toNormalizedFilePath' files) let (worked, failed) = partition fst $ zip (map isJust results) files when (failed /= []) $ putStr $ unlines $ "Files that failed:" : map ((++) " * " . snd) failed let files xs = let n = length xs in if n == 1 then "1 file" else show n ++ " files" putStrLn $ "\nCompleted (" ++ files worked ++ " worked, " ++ files failed ++ " failed)" - return () + unless (null failed) (exitWith $ ExitFailure (length failed)) expandFiles :: [FilePath] -> IO [FilePath] expandFiles = concatMapM $ \x -> do @@ -177,12 +177,6 @@ expandFiles = concatMapM $ \x -> do fail $ "Couldn't find any .hs/.lhs files inside directory: " ++ x return files - -kick :: Action () -kick = do - files <- getFilesOfInterest - void $ uses TypeCheck $ HashSet.toList files - -- | Print an LSP event. showEvent :: Lock -> FromServerMessage -> IO () showEvent _ (EventFileDiagnostics _ []) = return () @@ -230,15 +224,15 @@ setNameCache nc hsc = hsc { hsc_NC = nc } loadSessionShake :: FilePath -> Action (FilePath -> Action (IdeResult HscEnvEq)) loadSessionShake fp = do se <- getShakeExtras - IdeOptions{optTesting} <- getIdeOptions - res <- liftIO $ loadSession optTesting se fp + IdeOptions{optTesting = IdeTesting ideTesting} <- getIdeOptions + res <- liftIO $ loadSession ideTesting se fp return (fmap liftIO res) -- | This is the key function which implements multi-component support.

Thanks @jneira for help discovering them all. There used to be linking errors but I no longer see those after the multi-cradle patch Non Nix ========= The table below shows a couple of combinations of cradles and ghcide versions in a non-Nix environment. All the version mismatches are now handled as follows: - "Cannot satisfy package" - `-package-id` flags referencing package versions not available (generally base) - "bad interface" - tried to load an interface file created by a different version of ghc cradle/ghcide | 8.6 | 8.8 | 8.10 --------------|-----|----|--- Cabal 8.6 | success | cannot satisfy package | cannot satisfy package Cabal 8.8 | cannot satisfy package | success | cannot satisfy package Cabal 8.10 | cannot satisfy package | cannot satisfy package | success Stack 8.6 | success | bad-interface | bad-interfac- Stack 8.8 | bad-interface | success | bad-interface Stack 8.10 | bad-interface | bad-interface | success Nix ========= Because Nix redefines the libdir to point at the run-time ghc installation, it's actually much easier to detect a version mismatch: just compare the compile-time and run-time libdirs --- exe/Main.hs | 424 ++++++++++++++++++-------------- ghcide.cabal | 3 +- src/Development/IDE/GHC/Util.hs | 22 +- stack-ghc-lib.yaml | 2 +- stack.yaml | 2 +- stack810.yaml | 2 +- stack84.yaml | 2 +- stack88.yaml | 3 +- 8 files changed, 252 insertions(+), 208 deletions(-) diff --git a/exe/Main.hs b/exe/Main.hs index 0096a06714..6c6a65f3e5 100644 --- a/exe/Main.hs +++ b/exe/Main.hs @@ -15,11 +15,12 @@ import Module import Arguments import Control.Concurrent.Async import Control.Concurrent.Extra -import Control.Exception +import Control.Exception.Safe import Control.Monad.Extra import Control.Monad.IO.Class import Data.Default import Data.Either +import Data.Foldable (for_) import Data.Function import Data.List.Extra import Data.Maybe @@ -69,7 +70,7 @@ import DynFlags (gopt_set, gopt_unset, updOptLevel, PackageFlag(..), PackageArg( import GhcMonad import HscTypes (HscEnv(..), ic_dflags) import GHC hiding (def) -import GHC.Check ( VersionCheck(..), makeGhcVersionChecker ) +import GHC.Check import Data.Either.Extra import HIE.Bios.Cradle @@ -152,7 +153,7 @@ main = do putStrLn "\nStep 3/4: Initializing the IDE" vfs <- makeVFSHandle debouncer <- newAsyncDebouncer - ide <- initialise def mainRule (pure $ IdInt 0) (showEvent lock) (logger Info) debouncer (defaultIdeOptions $ loadSessionShake dir) vfs + ide <- initialise def mainRule (pure $ IdInt 0) (showEvent lock) (logger minBound) debouncer (defaultIdeOptions $ loadSessionShake dir) vfs putStrLn "\nStep 4/4: Type checking the files" setFilesOfInterest ide $ HashSet.fromList $ map toNormalizedFilePath' files @@ -238,165 +239,178 @@ loadSession optTesting ShakeExtras{logger, eventer, restartShakeSession} dir = d -- Mapping from a Filepath to HscEnv fileToFlags <- newVar Map.empty :: IO (Var FlagsMap) - -- This caches the mapping from Mod.hs -> hie.yaml - cradleLoc <- memoIO $ \v -> do - res <- findCradle v - -- Sometimes we get C:, sometimes we get c:, and sometimes we get a relative path - -- try and normalise that - -- e.g. see https://github.com/digital-asset/ghcide/issues/126 - res' <- traverse IO.makeAbsolute res - return $ normalise <$> res' - - -- Create a new HscEnv from a hieYaml root and a set of options - -- If the hieYaml file already has an HscEnv, the new component is - -- combined with the components in the old HscEnv into a new HscEnv - -- which contains the union. - let packageSetup :: (Maybe FilePath, NormalizedFilePath, ComponentOptions) - -> IO (HscEnv, ComponentInfo, [ComponentInfo]) - packageSetup (hieYaml, cfp, opts) = do - -- Parse DynFlags for the newly discovered component - hscEnv <- emptyHscEnv - (df, targets) <- evalGhcEnv hscEnv $ - setOptions opts (hsc_dflags hscEnv) - dep_info <- getDependencyInfo (componentDependencies opts ++ maybeToList hieYaml) - -- Now lookup to see whether we are combining with an existing HscEnv - -- or making a new one.

Previously we conflated stale interface with other errors, and would regenerate in both cases. Now we only regenerate in the first case. Tentative fix for #597 * Split interface tests * Always recompile modules with TH splices Tentative fix for #614 TODO support stability * Fix expectDiagnostics in MacOs * Avoid File does not exist diagnostics for interface files Fixes #642 * Clarify interface tests * hlints * Performance fixes The previous changes were 10X slower, this is 20X faster than those, so 2X faster than upstream, for some benchmarks * formatting * Fix GetModificationTime identity The answer for a GetModification query is independent of the missingFileDiagnostics field (as the diagnostics are not part of the answer) * remove stale comment * Avoid calling ghcSessionDepsDefinition twice * Apply suggestions from code review Co-authored-by: Moritz Kiefer * Code review feedback * Address review feedback https://github.com/digital-asset/ghcide/pull/645/files/49b0d9ac65399edf82a7a9cbbb8d8b5420458d8d#r443383239 * Change recomp to direct cradle Co-authored-by: Zubin Duggal Co-authored-by: Moritz Kiefer --- src/Development/IDE/Core/Compile.hs | 55 ++++++----- src/Development/IDE/Core/FileStore.hs | 7 +- src/Development/IDE/Core/Rules.hs | 133 +++++++++++--------------- src/Development/IDE/Core/Shake.hs | 29 +++++- test/data/recomp/A.hs | 6 ++ test/data/recomp/B.hs | 4 + test/data/recomp/P.hs | 5 + test/data/recomp/hie.yaml | 1 + test/exe/Main.hs | 107 ++++++++++++++++++++- test/src/Development/IDE/Test.hs | 14 ++- 10 files changed, 245 insertions(+), 116 deletions(-) create mode 100644 test/data/recomp/A.hs create mode 100644 test/data/recomp/B.hs create mode 100644 test/data/recomp/P.hs create mode 100644 test/data/recomp/hie.yaml diff --git a/src/Development/IDE/Core/Compile.hs b/src/Development/IDE/Core/Compile.hs index f5754f7654..82bc042d28 100644 --- a/src/Development/IDE/Core/Compile.hs +++ b/src/Development/IDE/Core/Compile.hs @@ -38,7 +38,6 @@ import Development.IDE.GHC.Util import qualified GHC.LanguageExtensions.Type as GHC import Development.IDE.Types.Options import Development.IDE.Types.Location -import Outputable #if MIN_GHC_API_VERSION(8,6,0) import DynamicLoading (initializePlugins) @@ -59,8 +58,6 @@ import GhcMonad import GhcPlugins as GHC hiding (fst3, (<>)) import qualified HeaderInfo as Hdr import HscMain (hscInteractive, hscSimplify) -import LoadIface (readIface) -import qualified Maybes import MkIface import NameCache import StringBuffer as SB @@ -81,7 +78,6 @@ import qualified Data.Map.Strict as Map import System.FilePath import System.Directory import System.IO.Extra -import Data.Either.Extra (maybeToEither) import Control.DeepSeq (rnf) import Control.Exception (evaluate) import Exception (ExceptionMonad) @@ -564,29 +560,36 @@ loadHieFile f = do let nameCache = initNameCache u [] fmap (GHC.hie_file_result . fst) $ GHC.readHieFile nameCache f --- | Retuns an up-to-date module interface if available. +-- | Retuns an up-to-date module interface, regenerating if needed. -- Assumes file exists. -- Requires the 'HscEnv' to be set up with dependencies loadInterface - :: HscEnv + :: MonadIO m => HscEnv -> ModSummary - -> [HiFileResult] - -> IO (Either String ModIface) -loadInterface session ms deps = do - let hiFile = case ms_hsc_src ms of - HsBootFile -> addBootSuffix (ml_hi_file $ ms_location ms) - _ -> ml_hi_file $ ms_location ms - r <- initIfaceLoad session $ readIface (ms_mod ms) hiFile - case r of - Maybes.Succeeded iface -> do - session' <- foldM (\e d -> loadDepModuleIO (hirModIface d) Nothing e) session deps - (reason, iface') <- checkOldIface session' ms SourceUnmodified (Just iface) - return $ maybeToEither (showReason reason) iface' - Maybes.Failed err -> do - let errMsg = showSDoc (hsc_dflags session) err - return $ Left errMsg - -showReason :: RecompileRequired -> String -showReason MustCompile = "Stale" -showReason (RecompBecause reason) = "Stale (" ++ reason ++ ")" -showReason UpToDate = "Up to date" + -> SourceModified + -> m ([FileDiagnostic], Maybe HiFileResult) -- ^ Action to regenerate an interface + -> m ([FileDiagnostic], Maybe HiFileResult) +loadInterface session ms sourceMod regen = do + res <- liftIO $ checkOldIface session ms sourceMod Nothing + case res of + (UpToDate, Just x) + -- If the module used TH splices when it was last + -- compiled, then the recompilation check is not + -- accurate enough (https://gitlab.haskell.org/ghc/ghc/-/issues/481) + -- and we must ignore + -- it.

Create entrypoint for missing constraint code action, in order to have a more efficient parsing by routing to the relevant implementation. Fix type signature name parsing. Minor refactor. * Minor refactor From d999084820c342c3284506c44913250cfabe4e4f Mon Sep 17 00:00:00 2001 From: Matthew Pickering Date: Tue, 30 Jun 2020 10:22:20 +0100 Subject: [PATCH 514/703] Use stale information if it's available to answer requests quickly (#624) * Use stale information for hover and completions This introduces a new function `useWithStaleFast` which returns with stale information WITHOUT checking freshness like `use` and `useWithStale`. Greatly improve debug logging All actions triggered by shakeRun now also pass an identifier which means that the debug logging shows which actions are starting/finishing We also distinguish between internal and external events. By default external events are ones triggered by runAction and the debug output is displayed to the user in command line and --lsp mode. In order to see internal logging statements, there is a new flag called --verbose which also prints out internal events such as file modification flushes. Cleaner variant using runAfter Step 1: Do not run actions with shakeRun Queue implementation, living, breathing Use a priority queue to schedule shake actions. Most user actions are answered immediately with a cache but also spawn a shake action to check the cached value we consulted was up to date. * Remove DelayedActionExtra * hlint * Fix progress * Always block instead of fail on initial computation * Can block for code lens * Update docs Co-authored-by: Zubin Duggal --- cabal.project | 1 + exe/Arguments.hs | 2 + exe/Main.hs | 5 +- src/Development/IDE/Core/FileStore.hs | 18 ++ src/Development/IDE/Core/OfInterest.hs | 10 +- src/Development/IDE/Core/Rules.hs | 131 +++++++------ src/Development/IDE/Core/Service.hs | 19 +- src/Development/IDE/Core/Shake.hs | 217 ++++++++++++++++----- src/Development/IDE/LSP/HoverDefinition.hs | 15 +- src/Development/IDE/LSP/Notifications.hs | 7 +- src/Development/IDE/LSP/Outline.hs | 2 +- src/Development/IDE/Plugin/CodeAction.hs | 43 ++-- src/Development/IDE/Plugin/Completions.hs | 21 +- src/Development/IDE/Spans/AtPoint.hs | 28 +-- 14 files changed, 325 insertions(+), 194 deletions(-) create mode 100644 cabal.project diff --git a/cabal.project b/cabal.project new file mode 100644 index 0000000000..e6fdbadb43 --- /dev/null +++ b/cabal.project @@ -0,0 +1 @@ +packages: . diff --git a/exe/Arguments.hs b/exe/Arguments.hs index a41967fc99..22f035a486 100644 --- a/exe/Arguments.hs +++ b/exe/Arguments.hs @@ -14,6 +14,7 @@ data Arguments = Arguments ,argsShakeProfiling :: Maybe FilePath ,argsTesting :: Bool ,argsThreads :: Int + ,argsVerbose :: Bool } getArguments :: IO Arguments @@ -33,3 +34,4 @@ arguments = Arguments <*> optional (strOption $ long "shake-profiling" <> metavar "DIR" <> help "Dump profiling reports to this directory") <*> switch (long "test" <> help "Enable additional lsp messages used by the testsuite") <*> option auto (short 'j' <> help "Number of threads (0: automatic)" <> metavar "NUM" <> value 0 <> showDefault) + <*> switch (long "verbose" <> help "Include internal events in logging output") diff --git a/exe/Main.hs b/exe/Main.hs index 35e6e19952..cb20cde8ee 100644 --- a/exe/Main.hs +++ b/exe/Main.hs @@ -130,9 +130,10 @@ main = do , optTesting = IdeTesting argsTesting , optThreads = argsThreads } + logLevel = if argsVerbose then minBound else Info debouncer <- newAsyncDebouncer initialise caps (mainRule >> pluginRules plugins) -

Since we started reusing `.hi` files, this exposes a bug where definitions aren't available since a bad source span from the `.hi` file gets put into the NameCache. We rectify by ensuring the span in the NameCache always matches the one from the `.hie` file. This has surfaced because an interaction between the commit which uses `.hi` instead of retypechecking and the change to use the shared global NameCache to read `.hie` files. * Add test for missing definitions Co-authored-by: Matthew Pickering --- exe/Main.hs | 14 +- ghcide.cabal | 2 + src-ghc810/Development/IDE/GHC/HieBin.hs | 399 +++++++++++++++++++++++ src-ghc88/Development/IDE/GHC/HieBin.hs | 389 ++++++++++++++++++++++ src/Development/IDE/Core/Compile.hs | 9 +- src/Development/IDE/Core/Rules.hs | 11 +- src/Development/IDE/Core/Shake.hs | 17 +- src/Development/IDE/GHC/Compat.hs | 40 ++- test/exe/Main.hs | 9 + 9 files changed, 856 insertions(+), 34 deletions(-) create mode 100644 src-ghc810/Development/IDE/GHC/HieBin.hs create mode 100644 src-ghc88/Development/IDE/GHC/HieBin.hs diff --git a/exe/Main.hs b/exe/Main.hs index cb20cde8ee..5876595a1d 100644 --- a/exe/Main.hs +++ b/exe/Main.hs @@ -203,12 +203,12 @@ cradleToSessionOpts cradle file = do -- message about the fact that the file is being ignored.

Fixed by deduplicating these calls. getDocumentations is implemented on top of InteractiveEval.getDocs, which does a lot of Ghc setup internally and is very inefficient. Fixed by introducing a batch version of getDocs and batching all the calls in getSpanInfo name | success | samples | startup | setup | experiment | maxResidency ------------- | ------- | ------- | ------- | ----- | ---------- | ------------ edit (before) | True | 10 | 6.94s | 0.00s | 6.57s | 177MB edit (after) | True | 10 | 6.44s | 0.00s | 4.38s | 174MB * More performance improvements Played the deduplication trick on lookupName, which is slow for the same reasons as getDocs. Batching made a smaller difference in my measurements, so did not implement it * Fix redundant constraints * Skip the GHCi code paths for documentation We don't use the interactive module, so there's no reason to go through the GHCi code paths. Moreover, they apparently cause problems with ghc-lib. * Skip the GHCi paths for lookupName * Correctly load the module interface * Compatibility with GHC 8.4 and 8.6 * Fix ghc-lib build --- src/Development/IDE/Core/Compile.hs | 65 ++++++++- src/Development/IDE/GHC/Compat.hs | 1 + src/Development/IDE/GHC/Util.hs | 2 +- .../IDE/Plugin/Completions/Logic.hs | 30 ++-- src/Development/IDE/Spans/Calculate.hs | 136 +++++++++--------- src/Development/IDE/Spans/Common.hs | 6 -

Since we started reusing `.hi` files, this exposes a bug where definitions aren't available since a bad source span from the `.hi` file gets put into the NameCache. We rectify by ensuring the span in the NameCache always matches the one from the `.hie` file. This has surfaced because an interaction between the commit which uses `.hi` instead of retypechecking and the change to use the shared global NameCache to read `.hie` files. --- ghcide.cabal | 8 + src-ghc86/Development/IDE/GHC/HieAst.hs | 1784 +++++++++++++++++++++ src-ghc86/Development/IDE/GHC/HieBin.hs | 388 +++++ src-ghc86/Development/IDE/GHC/HieDebug.hs | 145 ++ src-ghc86/Development/IDE/GHC/HieTypes.hs | 534 ++++++ src-ghc86/Development/IDE/GHC/HieUtils.hs | 451 ++++++ src/Development/IDE/GHC/Compat.hs | 68 +- 7 files changed, 3349 insertions(+), 29 deletions(-) create mode 100644 src-ghc86/Development/IDE/GHC/HieAst.hs create mode 100644 src-ghc86/Development/IDE/GHC/HieBin.hs create mode 100644 src-ghc86/Development/IDE/GHC/HieDebug.hs create mode 100644 src-ghc86/Development/IDE/GHC/HieTypes.hs create mode 100644 src-ghc86/Development/IDE/GHC/HieUtils.hs diff --git a/ghcide.cabal b/ghcide.cabal index 1436a2a854..5ab79ad999 100644 --- a/ghcide.cabal +++ b/ghcide.cabal @@ -155,6 +155,14 @@ library Development.IDE.Plugin.CodeAction.RuleTypes Development.IDE.Plugin.Completions.Logic Development.IDE.Plugin.Completions.Types + if (impl(ghc > 8.5) && impl(ghc < 8.7)) && !flag(ghc-lib) + hs-source-dirs: src-ghc86 + other-modules: + Development.IDE.GHC.HieAst + Development.IDE.GHC.HieBin + Development.IDE.GHC.HieTypes + Development.IDE.GHC.HieDebug + Development.IDE.GHC.HieUtils if (impl(ghc > 8.7) && impl(ghc < 8.10)) || flag(ghc-lib) hs-source-dirs: src-ghc88 other-modules: diff --git a/src-ghc86/Development/IDE/GHC/HieAst.hs b/src-ghc86/Development/IDE/GHC/HieAst.hs new file mode 100644 index 0000000000..d53f329865 --- /dev/null +++ b/src-ghc86/Development/IDE/GHC/HieAst.hs @@ -0,0 +1,1784 @@ + +{- +Forked from GHC v8.8.1 to work around the readFile side effect in mkHiefile + +Main functions for .hie file generation +-} +{- HLINT ignore -} +{-# LANGUAGE OverloadedStrings #-} +{-# LANGUAGE FlexibleInstances #-} +{-# LANGUAGE UndecidableInstances #-} +{-# LANGUAGE FlexibleContexts #-} +{-# LANGUAGE TypeSynonymInstances #-} +{-# LANGUAGE ScopedTypeVariables #-} +{-# LANGUAGE TypeFamilies #-} +{-# LANGUAGE TypeApplications #-} +{-# LANGUAGE AllowAmbiguousTypes #-} +{-# LANGUAGE ViewPatterns #-} +{-# LANGUAGE DeriveDataTypeable #-} +{-# LANGUAGE DataKinds #-} +module Development.IDE.GHC.HieAst ( mkHieFile ) where + +import Avail ( Avails ) +import Bag ( Bag, bagToList ) +import BasicTypes +import BooleanFormula +import Class ( FunDep ) +import CoreUtils ( exprType ) +import ConLike ( conLikeName ) +import Desugar ( deSugarExpr ) +import FieldLabel +import HsSyn +import HscTypes +import Module ( ModuleName, ml_hs_file ) +import MonadUtils ( concatMapM, liftIO ) +import Name ( Name, nameSrcSpan, setNameLoc ) +import SrcLoc +import TcHsSyn ( hsLitType, hsPatType ) +import Type ( mkFunTys, Type ) +import TysWiredIn ( mkListTy, mkSumTy ) +import Var ( Id, Var, setVarName, varName, varType ) +import TcRnTypes +import MkIface ( mkIfaceExports ) + +import Development.IDE.GHC.HieTypes +import Development.IDE.GHC.HieUtils + +import qualified Data.Array as A +import qualified Data.ByteString as BS +import qualified Data.Map as M +import qualified Data.Set as S +import Data.Data ( Data, Typeable ) +import Data.List (foldl', foldl1' ) +import Control.Monad.Trans.Reader +import Control.Monad.Trans.Class ( lift ) + +-- These synonyms match those defined in main/GHC.hs +type RenamedSource = ( HsGroup GhcRn, [LImportDecl GhcRn] + , Maybe [(LIE GhcRn, Avails)] + , Maybe LHsDocString ) +type TypecheckedSource = LHsBinds GhcTc + +-- | Marks that a field uses the GhcRn variant even when the pass +-- parameter is GhcTc.

haskell-language-server can also reuse this logic. Note that this sublibrary is public so it requires cabal-version: 3.0 Part of the work towards #478 * Move Development.IDE.Session into ghcide itself Sublibraries do not seem to play well. Hide this behind the ghc-lib flag so that the Haskell specific hie-bios stuff can be disabled Note that we need to put the template-haskell part of this module into a separate module because of an access exception when compiling with Stack, GHC 8.10.1 and Windows. --- exe/Main.hs | 606 +---------------- ghcide.cabal | 42 +- session-loader/Development/IDE/Session.hs | 634 ++++++++++++++++++ .../Development/IDE/Session/VersionCheck.hs | 17 + 4 files changed, 680 insertions(+), 619 deletions(-) create mode 100644 session-loader/Development/IDE/Session.hs create mode 100644 session-loader/Development/IDE/Session/VersionCheck.hs diff --git a/exe/Main.hs b/exe/Main.hs index 0f2e9fcfe2..03211fd4f0 100644 --- a/exe/Main.hs +++ b/exe/Main.hs @@ -1,32 +1,18 @@ -- Copyright (c) 2019 The DAML Authors.

DAML is a smart contract language targeting distributed-ledger runtimes, based on [GHC](https://www.haskell.org/ghc/) with custom language extensions. The DAML programming language has [an IDE](https://webide.daml.com/), and work was done to separate off a reusable Haskell-only IDE (what is now `ghcide`) which the [DAML IDE then builds upon](https://github.com/digital-asset/daml/tree/master/compiler/damlc). Since that time, there have been various [non-Digital Asset contributors](https://github.com/digital-asset/ghcide/graphs/contributors), in addition to continued investment by Digital Asset. All contributions require a [Contributor License Agreement](https://cla.digitalasset.com/digital-asset/ghcide) that states you license the code under the [Apache License](LICENSE). +The code behind `ghcide` was originally developed by [Digital Asset](https://digitalasset.com/) as part of the [DAML programming language](https://github.com/digital-asset/daml).

The project has been handed over to Haskell.org as of September 2020. The Haskell community [has](https://github.com/DanielG/ghc-mod) [various](https://github.com/chrisdone/intero) [IDE](https://github.com/rikvdkleij/intellij-haskell) [choices](http://leksah.org/), but the one that had been gathering momentum is [`haskell-ide-engine`](https://github.com/haskell/haskell-ide-engine#readme). Our project owes a debt of gratitude to the `haskell-ide-engine`. We reuse libraries from their ecosystem, including [`hie-bios`](https://github.com/mpickering/hie-bios#readme) (a likely future environment setup layer in `haskell-ide-engine`), [`haskell-lsp`](https://github.com/alanz/haskell-lsp#readme) and [`lsp-test`](https://github.com/bubba/lsp-test#readme) (the `haskell-ide-engine` [LSP protocol](https://microsoft.github.io/language-server-protocol/) pieces). We make heavy use of their contributions to GHC itself, in particular the work to make GHC take string buffers rather than files. -The best summary of the architecture of `ghcide` is available [this talk](https://www.youtube.com/watch?v=cijsaeWNf2E&list=PLxxF72uPfQVRdAsvj7THoys-nVj-oc4Ss) ([slides](https://ndmitchell.com/downloads/slides-making_a_haskell_ide-07_sep_2019.pdf)), given at [MuniHac 2019](https://munihac.de/2019.html).

This is particularly interesting for people building command line tools using `ghcide`, like the our DAML compiler at Digital Asset. tools with command line drivers, like us at Digital Asset. I would argue that VS Code has the ultimate authority on this since we can't change what it displays without also moving the squiggly lines.

This change makes that a bit easier and improves the documentation and code structure. The new structure is: - lib:shake-bench - a Cabal library with functions to generate Shake rules - ghcide:bench:benchHist - the ghcide instantiation of the above Shake rules That's not to say that shake-bench is completely decoupled from ghcide - there are still plenty of assumptions on how the benchmarks are organized, their outputs, etc. But with a little bit of effort, it should be easy to make these rules more reusable * Fix nix build * Fix license * hlints and redundant imports * more hlints * Exclude shake-bench from the stack build --- .hlint.yaml | 1 -

GetFileContents runs and since the contents of the file haven't changed since the last time it ran, early cutoff skips everything donwstream Since TypeCheck is skipped, the empty set of diagnostics stays published until another edit comes. The goal of this change is to prevent setStageDiagnostics from losing diagnostics from other stages. To achieve this, we recover the old diagnostics for all stages and merge them with the new stage. * Fix hlint * Use Map.insert for clarity * Fix redundant imports * Fix "code actions after edit" experiment" --- bench/lib/Experiments.hs | 8 +- exe/Arguments.hs | 2 + exe/Main.hs | 10 ++- ghcide.cabal | 1 + src/Development/IDE.hs | 1 - src/Development/IDE/Core/FileStore.hs | 10 --- src/Development/IDE/Core/RuleTypes.hs | 52 +++++++++++++ src/Development/IDE/Core/Rules.hs | 14 ++-- src/Development/IDE/Core/Service.hs | 2 +- src/Development/IDE/Core/Shake.hs | 100 +++++++----------------- src/Development/IDE/Plugin/Test.hs | 40 +++++++++- test/exe/Main.hs | 98 +++++++++++++++++++++-- test/src/Development/IDE/Test.hs | 108 +++++++++++++++++--------- 13 files changed, 309 insertions(+), 137 deletions(-) diff --git a/bench/lib/Experiments.hs b/bench/lib/Experiments.hs index d550d8ba07..84ad2eaa42 100644 --- a/bench/lib/Experiments.hs +++ b/bench/lib/Experiments.hs @@ -115,7 +115,13 @@ experiments = ) ( \p doc -> do changeDoc doc [hygienicEdit] - whileM (null <$> waitForDiagnostics) + waitForProgressDone + -- NOTE ghcide used to clear and reinstall the diagnostics here + -- new versions no longer do, but keep this logic around + -- to benchmark old versions sucessfully + diags <- getCurrentDiagnostics doc + when (null diags) $ + whileM (null <$> waitForDiagnostics) not . null <$> getCodeActions doc (Range p p) ) ] diff --git a/exe/Arguments.hs b/exe/Arguments.hs index 37f238b68c..11b4320d82 100644 --- a/exe/Arguments.hs +++ b/exe/Arguments.hs @@ -14,6 +14,7 @@ data Arguments = Arguments ,argsShakeProfiling :: Maybe FilePath ,argsOTMemoryProfiling :: Bool ,argsTesting :: Bool + ,argsDisableKick :: Bool ,argsThreads :: Int ,argsVerbose :: Bool } @@ -35,5 +36,6 @@ arguments = Arguments <*> optional (strOption $ long "shake-profiling" <> metavar "DIR" <> help "Dump profiling reports to this directory") <*> switch (long "ot-memory-profiling" <> help "Record OpenTelemetry info to the eventlog.

The rule of thumb is that if the modules of the package were compiled with -split-sections then building the HSfoo.o is worthwhile because it saves time when loading the package into GHCi.
