The API for setting targets has - changed as is now - - updateTargets :: Targets -> IdeSessionUpdate - - where - - data Targets = TargetsInclude [FilePath] - | TargetsExclude [FilePath] - - - Ability to change include paths dynamically (#178). Note that changing - include paths (as well as changing targets) will cause a server restart. - - - Ability to hide and unhide packages dynamically, and change Safe - Haskell flags dynamically (#185, #224). Unlike we had previously - thought, we can in fact do this without a server restart. - - - Executables can now be run from ide-backend with the same API as - running snippets (#181). Most of our runStmt tests in the test suite - now have a corresponding runExe test (which can however be disabled with - the --no-exe test suite option). Note that we _do_ expect _some_ - semantic differences between tests and snippets through the API; in - particular, since we don't manage the executable, we cannot affect its - I/O buffering modes or encoding settings. Also, the RunActions returned - by runExe eventually return an ExitCode rather than a RunResult. - - - Snippets now run as independent processes and the "Running" state is - gone from ide-backend. The RPC framework is modified to be able to - deal with multiple RPC conversations (and fixed some bugs that were - introduced in that change: #225); RPC conversations with the split off - processes happen over named pipes. This uses 'forkProcess', for which - we have identified and fixed a number of ghc RTS bugs (#9377, #9347, - \#9296, #9295, #9284). The use of a separate process is necessary - because we need to be able to change process global state for the - snippet (buffering, current working directory, value of getArgs, etc.). - Issue #206 was partly related to these ghc bugs. One consequence of - this is that it is now possible to change data files while a snippet is - running (#176). - - - The API for changing environment variables is changed (#202). It is now - - updateEnv :: [(String, Maybe String)] -> IdeSessionUpdate - - and is intended to be stateless rather than cumulative as it had been. - - - The API for setting options is changed. We no longer make a (public) - distinction between static ghc options and dynamic ghc options, and - the configStaticOpts are gone from the ide-backend configuration. - Instead, we simply have - - updateGhcOpts :: [String] -> IdeSessionUpdate - - and ide-backend handles the distinction entirely internally. Note that - so far the only option that we have come across that are truly static - (i.e., require a session restart) are changes to the linker flags. - Anything else (including changes to the package visibility) we can - handle server side without a restart. - - - Similarly, removed the relative includes from the configuration and - moved them to the session init parameters where they should have been - from the start (because they can be changed dynamically). - - Note that you need path `""` in relative includes for `updateTargets` - and `buildExe` to be aware of the same set of source directories - (#184). - - * Closed issues: - - - Asymptotic performance improvement (#167, ghc #7478) and added - performance unit tests. These are very rough at the moment and can fail - simply due to high system load, for instance. - - - Make sure ghc sees changes to dependent files (#134, ghc #7473). - - - We correctly wipe out the GHC search path before setting our own (#169). - - - Invoking the Cabal functions that print to stdout and stderr is now - done via our RPC (#180) that starts a separate binary - ide-backend-exe-cabal. This is necessary so that we can change process - global state such as the current working directory without affecting - the rest of the system. - - The stdout output it redirected to a log file and analyzed to provide - Progress updates. The binary has to be present on the path. E.g., when - you run ide-backend tests you can add the extra fpco-stock-7.4 path - component (see SETUP.md), into which the binary is installed by default - with 'cabal install': - - IDE_BACKEND_EXTRA_PATH_DIRS=~/env/fpco-patched-7.4/local/bin:~/env/fpco-patched-7.4/dot-cabal/bin:~/env/fpco-stock-7.4/dot-cabal/bin \ - IDE_BACKEND_PACKAGE_DB=~/env/fpco-patched-7.4/dot-ghc/snippet-db \ - dist/build/ghc-errors/ghc-errors - - - forceCancel of a snippet now sends sigKILL rather than "requesting" - a server shutdown (#173). - - - Added updateRtsOpts to the API and set default stack size to 8MB (#191). - However, limiting stack size does not seem to work for ghc 7.4. ghci - manages it so there must be a way, but simply starting the server with - +RTS -K.. -RTS does is not sufficient (#258). - - - configRelativeIncludes taken into account when building C files (#212). - - - Make it possible to override path to GHC (#205). - - - Disable idle GC in the server (#206). - - - Don't lose location information when getting multiple error messages - (#213). - - - Make sure we don't lose output from C code by flushing C buffers as well - as Haskell buffers (#210). - - - Make sure that we can set linker flags dynamically (#214). - - - Fix inconsistent user package database loading (#221). - - - Make sure that runStmt can safely be interrupted without putting the - main session in an inconsistent state or leading to deadlock (#219, - \#220) and that it will terminate the server if it does get interrupted - (#231). - - - Make sure server terminates when client does (#194). - - - Be consistent (GHC API/exe building) about Haskell2010 (#190). - - - Better fix to #119: we no longer wipe the entire build directory when - building executables, but instead update the timestamps of .o files. - This gives us better performance when building executables. - - - Unload object file when a previously correct C file is replaced with - one containing errors (#201) or when the C file is removed from the - session (#241). - - - Make sure object files are resolved correctly, even if they were - previously loaded (#228, #230) and properly report linker errors - to the client (#242). - - - Make sure relevant ghc options are passed to ghc when compiling C files - (#218) and recompile C files when options are changed (#214). - - - Make sure calling Haddock does not change the source files in the - session (#238). - - - Make sure the client gets as much information as possible on a hard - server crash (#239). - - - Remove previous error logs on calls to buildExe etc (#245) so that - on a call to buildExe we don't leave confusing old error messages lying - around. - - - Make sure to generate position independent code (#244). - - * Other minor bug fixes and changes: - - - Don't skip ghc progress messages that include "[TH]" (these were - confusing our parser) - - Changed bounds on dependencies - - Internal refactoring of the updateSession logic, which is now a lot - more comprehensible (mostly possible now because we no longer have - a "Running" state, and starting a snippet is now independent of the - main session). This implies a minor API change; IdeSessionUpdate is no - longer a Monad, and no longer takes a type argument. It still satisifes - Monoid, however, and this should barely affect client code (other than - perhaps a type annotation here and there, replacing `IdeSessionUpdate - ()` with `IdeSessionUpdate`). This also resolves a race condition that - was present in `updateSession` (where a concurrent update session might - grab the session lock while the first session update was attempting to - restart the session). Also, better treatment of exceptions during - session updates (#250, #253). - - Added updateDeleteManagedFiles session update to remove all managed - (source and data) files from a session. - - Catch and report exceptions thrown by Haddock building. - - * Test suite has been significantly refactored (#217, #237, #231), and is - now far more modular (dramatically improved compile times), can re-use - sessions for tests (which has brought to light quite a few bugs) as well - as in parallel (although the latter has not been tested sufficiently - yet), and uses tasty rather than test-framework. Various minor fixes to - the tests: - - - GHC 7.8 started using fancy (unicode) quotes, which confused some tests. - - Added test for .hsboot files in subdirectories (#177) - - Don't rely on availability of profiling libs in the tests. - - Don't rely on the IsString instance for Data.ByteString because it - uses `pack` and thus throws away UTF8 data (#234). - - Test for package registration fixed (#250). Note that a running session - will NOT notice newly installed package until it is restarted (nor will - it notice that it needs to be restarted -- this needs to be initiated - with a call to restartSession). - - * Open issues: - - - The ghc linker is broken in the threaded runtime, which will affect - bindings to C libraries (ghc #8648). We suspect that #175 is caused - by this. - - On OSX we do not detect when a snippet server dies (#229). The problem - does not occur on Linux. - - buildExe sometimes compiles modules more than once (#189). This should - not change anything semantically but we have to allow for it in the - tests (since we get more progress messages than we expect) and of course - it has a performance impact. - - Building executables leaves .o and .dyn_o files in the session src/ - directory (#249). The client should not really be affected by this - however. - - We currently _always_ restart the session when the relative includes - or targets change. This is correct but conservative and unnecessary. - Figuring out precisely when this is needed however is rather difficult - and probably not worth the effort. (Note that we don't restart when - the options "change" (by a call to updateTargets etc) to their current - value in the session. - - The debugging API is **disabled** in this release, as it needs to be - updated to work with the separate server (forkProcess) for running - snippets. - - Limiting stack size does not work for 7.4 (#258). - - * Version 0.8. - - This is a major new release with a lot of new functionality, bug fixes, and - some minor API changes. - - * New functionality: support for GHC 7.8, and make sure that a single - ide-backend client library, compiled with a stock ghc, can talk to - multiple ide-backend-servers (one for ghc 7.4, one for ghc 7.8) - (#137, #147, #148, #149, #150, #151, #158, ghc #8006, ghc #8067, - ghc Hooks proposal). Setup instructions are included in "setup/SETUP.md". - - NOTE: This requires new versions of both ghc 7.4 and ghc 7.8. - - - For ghc 7.4: commit 8c021d1 (branch ide-backend-experimental-74). - Differences from the official release: backported Hooks; backported - fixes to #1381, #7040, #7231, #7478, #8006, #8333 - (ide-backend issues #145 and #161). Also applied patch for #4900, - although that patch is not accepted in HEAD yet (necessary for #118). - - - For ghc 7.8: commit e0f0172 (branch ide-backend-experimental-78). - Since there is no official release of ghc yet, this picks a - semi-random snapshot of the ghc tree (a93f857). Our branch differs - from this snapshot by only a single patch (for #118/ghc #4900); we - have made various other patches, but they have all been included in - the official tree. - - Note that we now use ghc's standard non-release version numbering - (7.4.2. and 7.7.). ide-backend supports a higher level query - (getGhcVersion :: Query GhcVersion) where - - data GhcVersion = GHC742 | GHC78 - - * New functionality: debugging API (#131). - - Breakpoints can be set/cleared using - - setBreakpoint :: IdeSession - -> ModuleName - -> Public.SourceSpan - -> Bool - -> IO (Maybe Bool) - - The existing API for binding subexpressions can be used to construct - SourceSpans. - - When a breakpoint is set, snippets can stop with a new RunResult - - data RunResult = - ... - | RunBreak - - They can be resumed using - - resume :: IdeSession -> IO (RunActions Public.RunResult) - - Information about the current breakpoint (if any) can be got using - - getBreakInfo :: Query (Maybe BreakInfo) - - data BreakInfo = BreakInfo { - breakInfoModule :: Public.ModuleName - , breakInfoSpan :: SourceSpan - , breakInfoResultType :: Public.Type - , breakInfoVariableEnv :: Public.VariableEnv - } - - type VariableEnv = [(Name, Type, Value)] - - Variables can be printed and/or forced using - - printVar :: IdeSession - -> Public.Name - -> Bool - -> Bool - -> IO Public.VariableEnv - - The two booleans indicate whether new variables should be bound (cf. - ghci's :print vs :sprint) and whether the value should be forced (:print - vs :force). This is only valid during an active breakpoint. - - Not all of ghci's debugging funtionality is yet supported; this is - documented in more detail in the ticket (#131, also #136). Note also - that the API may not be entirely stable yet. In particular, having - printVar independent of RunActions is unsatisfactory; fixing this _may_ - change the runStmt API too. This is documented in great detail in a new - ticket (#153). - - * New functionality: generate Hoogle/Haddock (#70). Please read - the documentation of @buildDoc@, test and suggest improvements. See also - https://github.com/fpco/ide-backend/issues/70#issuecomment-32031570 - - * New functionality: distinguish between KindError and KindServerDied, and - hide the "internal exception" when showing external exceptions (#135) - - * New functionality: allow to set compilation targets (#152) - - updateTargets :: Maybe [FilePath] -> IdeSessionUpdate () - - As part of this also added a new field called configRelativeIncludes to - SessionConfig (#156). To see why this is necessary, consider "module A" - in "foo/bar/A.hs" and "module B" in "foo/bar/B.hs", where module B - imports module A, and we specify "foo/bar/B.hs" as the target. Then ghc - will be unable to find module A because it won't know to look in - directory "foo/bar" (before updateTargets this was not an issue because - we specified all modules paths explicitly to ghc). Now - configRelativeIncludes can be used to tell ghc where to look (in this - case, it should be set to ["foo/bar"]). - - Note that buildExe and co do not yet take these targets into account - (#154), except for configRelativeIncludes, which are, in particular, - inserted into the hs-source-dirs field of .cabal, if set. - - Also, fixed bug where we would not pass -i to the ghc server on session - restart (this bug was mostly invisible when we were providing all source - files explicitly). - - * New functionality: support for boot files (#155, #157). - - * New functionality: support C files (and .h files), both through - the API (where ide-backend-server compiles the .c files - into .o files and dynamically loads/unloads these object files) - and in executable generation (#122). - - * New functionality: specify (as the first argument of buildExe) - additional arguments for ghc when building executables (#159). - - * Bugfix: setting ghc options is now stateless. We still have - - configStaticOpts :: [String] - - as before, which can be used for things like package options, but changed - - updateGhcOptions :: Maybe [String] -> IdeSessionUpdate - - to - - updateDynamicOpts :: [String] -> IdeSessionUpdate - - with the following semantics: the full set of active options is those - specified in configStaticOpts, plus those (and only those) set in the - last call to updateDynamicOpts. In other words, setting - - updateDynamicOpts ["-Wall", "-Werror"] - - and then later - - updateDynamicOpts ["-Wall"] - - now does the right thing (#115). - - * Bugfix: Make sure ID info is updated on code changes (fixed a caching - problem) (#142) - - * Bugfix: Make sure that updating static files triggers recompilation - (#118). This is fixed by means of a ghc patch (in both 7.4 and 7.8; ghc - issue #4900). - - * Bugfix: Avoid confusing error message in buildExe for code with type - errors (#145, #160). - - * Better way to deal with async exceptions in snippet interrupts in ghc - (#58, ghc issue #8006). The new solution works in both 7.4 and 7.8, and - in both "regular" execution of snippets and in execution with - breakpoints enabled/resumed execution (#133). The new approach is now in - the official GHC tree. - - * Upgraded to Cabal 1.18.1.2 (necessary to support GHC 7.8), and set - things up so that it generates the necessary dynlibs when using 7.8. - Although Cabal 1.18 reports problems slightly differently to Cabal - 1.16, ide-backend attempts to hide this difference (#146). There is - still a minor problem on OSX when using an in-place compiler due to - either a bug in ghc or a bug in cabal (#8266); see #164. - - * Minor API changes: - - - RunActions now has kind * -> * ; what was previously just "RunActions" - is now (from the client's perspective) "RunActions RunResult" - - String argument to RunOk has been removed. - - IdeSessionUpdate now has kind * -> * ; what was previously just - "IdeSessionUpdate" is now "IdeSessionUpdate ()". IdeSessionUpdate - has been given a Monad instance. - - updateModule* is now called updateSourceFile* (because it is used for - more than just Haskell modules). - - * Merged pull requests - - - Use binary-ide-backend throughout (#144) - - Tweaks to getDotCabal (#141) - - * Test-suite modificatons: - - - Test for #134: multiple changes to TH dependent files in one second - - Test for #32: Internal paths in error messages - - Test for #50: Async problem with snippet interrupt - - Test for fpco/fpco/#3043: constraints in monotypes - - Fixed non-deterministic failure of test for #58 (#143) - - Updated tests to support for 7.4 and 7.8 (mark allowable differences, - use alpha-equivalence rather than syntactic identity to compare - types, etc.), and be less picky about package versions - - Others, testing most of the features and fixes in this release - - * Isolated a bug in sqlite which was causing #104. - - * Known issue: tracked #125 down to a bug in the GHC RTS, and reported - this (#165, https://ghc.haskell.org/trac/ghc/ticket/8648). There is no - fix yet though. - - * Version 0.7.1 - - * New functionality: types of subexpressions (#50). Known issues: - - - We sometimes report multiple types for the same span (see comments - at the end of https://github.com/fpco/ide-backend/issues/50). - - * New functionality: report use sites of identifiers (#129) - - * New functionality: Generate .cabal files (#127) - - - Note that library data files are not installed. This should be easy - to add if/when that is needed. Just let us know. - - * Efficiency of construction of type information (and especially - autocompletion information) has been improved (#132). - - * Move license catenation (#72) documentation to haddocks, - flesh it out, make code more readable, improve error output, - fix a recently broken test - - * Add configLicenseFixed to hard-code packages with hidden - .cabal files (#72) - - * Optimize license catenation and add some benchmark tests (#72) - - * Bugfix: for ghc progress messages in projects with 10 or more modules - the first 9 progress message were not parsed correctly because we didn't - allow for whitespace in between '[' and the first number ("[ 1 of 10]"). - - * Merged pull requests: - - - Load CoreLicenses.txt via Template Haskell (#128) - - Less license failures (#126) - - Use System.IO.UTF8 to avoid character encoding issues (#117) - - * Version 0.7.0.2 - - * Use System.IO.UTF8 to avoid character encoding issues (fpco/fpco#2232) - - * Removing non-existent files should not throw an exception - - * Relaxed bounds on process, directory, tagged, and use crypto-api 0.12 - and aeson 0.6.2 - - * Use binary 0.7 (as binary-ide-backend); improved Binary instance for - Text that avoids lots of small chunks, and use the incremental API - from binary 0.7 to avoid the use of lazy I/O - - * Clear the build directory in buildExe (temporary fix for #119) - - * Avoid stack overflow in Binary instance for lazy bytestrings (#121) - - * Version 0.7.0.1 - - * Bugfix: make sure restartSession passes the configPackageDBStack - to ghc (#114) - - * Version 0.7.0.0 - - NOTE. This release includes a number of small API changes and behavioural - changes since 0.6.0.2. - - * Report server crashes as SourceErrors, and implicitly restart the session - on the _next_ call to updateSession (#107). Note that if the server is - in dead state (i.e., after the serve crash and before the next call to - updateSession) a call to runStmt will throw an exception (just like when - you call runStmt when no code is compiled at all). It is the - responsibility of the client code to check for source errors - (using getSourceErrors) before calling runStmt. - - * It is now possible to reuse previously generated cabal macros, in order - to improve performance (#109). The type of initSession has changed to - - initSession :: SessionInitParams -> SessionConfig -> IO IdeSession - - where - - data SessionInitParams = SessionInitParams { - sessionInitCabalMacros :: Maybe BSL.ByteString - } - - Similarly, restartSession now has type (#113) - - restartSession :: IdeSession -> Maybe SessionInitParams -> IO () - - When passed Nothing it will leave the cabal macros unchanged, but when - passed a SessionInitParams it will regenerate them or use a previously - regenerated cabal macros file. - - The generated cabal macros can be accessed using - - getCabalMacros :: Query BSL.ByteString - - * Extended the Progress data type (#112) to contain the number of steps as - well as a progress message. See the comments in the ticket and in the - Haddock for Progress for some limitations, however (briefly, during - compilation, we get non-contiguous and possibly out of order progress - updates from ghc: [4/13], [8/13], done). - - * It is now possible to specify additional program search directories in - *addition* to the normal `$PATH` when creating a session (#99). - - data SessionConfig = SessionConfig { - configExtraPathDirs :: [FilePath] - ... - - This allows different sessions within the same process (that share the - same `$PATH` env var) to have different program search paths. In - particular this can be used to select the instance of ghc by controlling - which ghc binary is found. - - Note that the `configExtraPathDirs` are in addition to the `$PATH`, they - are searched after the `$PATH`. - - * Version 0.6.0.2 - - * Fix problem with cabal_macros in package databases with multiple - versions of the same package. - - * Merge pull request from fpco/looger (#105) - - * Traverse class default methods for id info (#106) - - * Version 0.6.0.1 - - * Now uses a private Cabal fork as a sub-repo. Branch is ide-backend. - The package is renamed as Cabal-ide-backend. You will need to install - this and then ghc-pkg hide it or it will cause problems (e.g. ambigious - modules when building Setup.hs files). - - * Fix for ticket #103. The macro generation should now be faster. - No interface change for this. - - * Version 0.6 - - * baseline version for new version + release protocol diff --git a/TestSuite/TestSuite.hs b/TestSuite/TestSuite.hs --- a/TestSuite/TestSuite.hs +++ b/TestSuite/TestSuite.hs @@ -1,5 +1,9 @@ module Main where +import Data.Foldable (forM_) +import Data.List (isPrefixOf) +import System.Process (readProcess) +import System.Environment import Test.HUnit import Test.Tasty @@ -75,8 +79,37 @@ ] main :: IO () -main = - defaultMainWithIngredients ings $ testSuite $ \env -> +main = do + -- Yes, this is hacky, but I couldn't figure out how to easily do + -- this with tasty's API...
