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.<date> and 7.7.<date>). 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
