* Correct Windows libdir assumptions.Tamar Christina2017-02-231-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | GHC and ghc-pkg make some pretty hard assumptions about where they're running on Windows. They assume that they are always running from `foo/bin/ghc.exe` and that to find the `lib` folder they can drop `bin/ghc.exe` from the base path and append `lib`. This is already false for the testsuite, which when testing thenbindist has one test which puts the binaries in `inplace/test spaces`. For some reason before this was either being skipped or mysteriously passing. But as of `2017.02.11` our luck ran out. the testsuite triggers a failure such as those in #13310 Let's soften the assumption and just check that `../lib` exists instead. 80 chars Test Plan: ./validate Reviewers: austin, erikd, bgamari Reviewed By: bgamari Subscribers: thomie, #ghc_windows_task_force Differential Revision: https://phabricator.haskell.org/D3158

* Support for abi-depends for computing shadowing.Edward Z. Yang2016-12-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is a complete fix based off of ed7af26606b3a605a4511065ca1a43b1c0f3b51d for handling shadowing and out-of-order -package-db flags simultaneously. The general strategy is we first put all databases together, overriding packages as necessary. Once this is done, we successfully prune out broken packages, including packages which depend on a package whose ABI differs from the ABI we need. Our check gracefully degrades in the absence of abi-depends, as we only check deps which are recorded in abi-depends. Contains time and Cabal submodule update. Signed-off-by: Edward Z.

* Add and use a new dynamic-library-dirs field in the ghc-pkg infoDuncan Coutts2016-10-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Build systems / package managers want to be able to control the file layout of installed libraries. In general they may want/need to be able to put the static libraries and dynamic libraries in different places. The ghc-pkg library regisrtation needs to be able to handle this. This is already possible in principle by listing both a static lib dir and a dynamic lib dir in the library-dirs field (indeed some previous versions of Cabal did this for shared libs on ELF platforms). The downside of listing both dirs is twofold. There is a lack of precision, if we're not careful with naming then we could end up picking up the wrong library. The more immediate problem however is that if we list both directories then both directories get included into the ELF and Mach-O shared object runtime search paths. On ELF this merely slows down loading of shared libs (affecting prog startup time). On the latest OSX versions this provokes a much more serious problem: that there is a rather low limit on the total size of the section containing the runtime search path (and lib names and related) and thus listing any unnecessary directories wastes the limited space. So the solution in this patch is fairly straightforward: split the static and dynamic library search paths in the ghc-pkg db and its use within ghc. This is a traditional solution: pkg-config has the same static / dynamic split (though it describes in in terms of private and public, but it translates into different behaviour for static and dynamic linking). Indeed it would make perfect sense to also have a static/dynamic split for the list of the libraries to use i.e. to have dynamic variants of the hs-libraries and extra-libraries fields. These are not immediately required so this patch does not add it, but it is a reasonable direction to follow. To handle compatibility, if the new dynamic-library-dirs field is not specified then its value is taken from the library-dirs field. Contains Cabal submodule update. Test Plan: Run ./validate Get christiaanb and carter to test it on OSX Sierra, in combination with Cabal/cabal-install changes to the default file layout for libraries.

* Make InstalledUnitId be ONLY a FastString.Edward Z. Yang2016-10-081-8/+9
| | | | | | | | | | | | | | | | | | | | | It turns out that we don't really need to be able to extract a ComponentId from UnitId, except in one case. So compress UnitId into a single FastString. The one case where we do need the ComponentId is when we are compiling an instantiated version of a package; we need the ComponentId to look up the indefinite version of this package from the database. So now we just pass it in as an argument -this-component-id. Also: ghc-pkg now no longer will unregister a package if you register one with the same package name, if the instantiations don't match.

* Error early when you register with too old a version of Cabal.Edward Z. Yang2016-02-101-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the GHC 8.0 RCs, multiple users reported a very strange error whereby GHC would complain that the symbols names recorded in interface files did not match the expected name. The reason for this is that they were using an old version of Cabal which chose symbol names differently from the installed package ID ('id' field) which the package was to be installed with; GHC 8.0 now mandates that these coincides. This change adds a test to ghc-pkg to make sure that 'id' and 'key' (which is how Cabal previously reported what the symbol name was supposed to be) match; if they don't match or key is missing, we assume that the Cabal was too old. Bikeshed points: - Should we offer more information about how to upgrade Cabal correctly (i.e. specify a version?) - Should we allow for a missing 'key'? If we allow for 'key' to be missing, we lose the ability to detect Cabal from GHC 7.8 or earlier being used. If we require it to be specified, then it will not be possible for Cabal to deprecate the (unused) field and remove it without having BC for 8.0. Signed-off-by: Edward Z.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we had an 'OriginalModule' type in ghc-boot which was basically identical to 'Module', and we had to do a bit of gyrating to get it converted into the right form. This commit introduces a new typeclass, 'DbModuleRep' which represents types which we know how to serialize to and from the (now renamed) 'DbModule' type. The upshot is that we can just store 'Module's DIRECTLY in the 'InstalledPackageInfo', no conversion needed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A small cosmetic change, but we have to do a bit of work to actually support it: - Cabal submodule update, so that Cabal passes us -this-unit-id when we ask for it. This includes a Cabal renaming to be consistent with Unit ID, which makes ghc-pkg a bit more scrutable. - Build system is updated to use -this-unit-id rather than -this-package-key, to avoid deprecation warnings. Needs a version test so I resurrected the old test we had (sorry rwbarton!) - I've *undeprecated* -package-name, so that we are in the same state as GHC 7.10, since the "correct" flag will have only entered circulation in GHC 8.0. - I removed -package-key. Since we didn't deprecate -package-id I think this should not cause any problems for users; they can just change their code to use -package-id. - The package database is indexed by UNIT IDs, not component IDs. I updated the naming here. - I dropped the signatures field from ExposedModule; nothing was using it, and instantiatedWith from the package database field. - ghc-pkg was updated to use unit ID nomenclature, I removed the -package-key flags but I decided not to add any new flags for now.

| | | | | | | | | | | | | | | | | | | | Trac #10796 exposes a way to make `template-haskell`'s `dataToQa` function freak out if using a `Data` instance that produces a `Constr` (by means of `toConstr`) using a function name instead of a data constructor name. While such `Data` instances are somewhat questionable, they are nevertheless present in popular libraries (e.g., `containers`), so we can at least make `dataToQa` aware of their existence. In order to properly distinguish strings which represent variables (as opposed to data constructors), it was necessary to move functionality from `Lexeme` (in `ghc`) to `GHC.Lexeme` in a new `ghc-boot` library (which was previously named `bin-package-db`).

* Add a workaround to allow older cabal-install to use ghc-7.10Duncan Coutts2015-02-091-6/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This should smooth the upgrade process for people and help with testing the 7.10 RCs. Otherwise people need to first install cabal-install-1.22 before they can use 7.10. The problem is that older cabal still used file-style package dbs for the inplace package db when building packages. The workaround is that both ghc and ghc-pkg will notice when cabal tells them to use a file style db e.g. "dist/package.conf.inplace" and, so long as that db is empty (ie content is []) then they'll instead us a dir style db with the same name but ".d" appended, so in this example that would be "dist/package.conf.inplace.d". We have to use a separate dir rather than transparently upgrading because old Cabal really assumes the path is a file, and if it encounters a dir it will fail. This seems to be enough for older Cabal to work, and may well be enough for other scripts that create dbs using "echo [] > package.conf". Test Plan: validate and check new and old cabal can sucessfully install things, including packages that have internal deps (ie using the inplace db) Reviewers: hvr, tibbe, austin Reviewed By: tibbe, austin Subscribers: thomie Differential Revision: https://phabricator.haskell.org/D628

* Refactor: use System.FilePath.splitSearchPathThomas Miedema2014-11-191-23/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: To address #2521 ("Trailing colon on GHC_PACKAGE_PATH doesn't work with ghc-pkg"), we were using a custom version of splitSearchPath (e4f46f5de). This solution however caused issue #9698 ("GHC_PACKAGE_PATH should be more lenient for empty paths"). This patch reverts back to System.FilePath.splitSearchPath (fixes #9698) and adresses (#2521) by testing for a trailing search path separators explicitly (instead of implicitly using empty search path elements). Empty paths are now allowed (ignored on Windows, interpreted as current directory on Posix systems), and trailing path separator still tack on the user and system package databases. Also update submodule filepath, which has a version of splitSearchPath which handles quotes in the same way as our custom version did. Test Plan: $ GHC_PACKAGE_PATH=/::/home: ./ghc-pkg list ... db stack: ["/",".","/home","<userdb>","<systemdb>"] ...

* Generalize exposed-modules field in installed package databaseEdward Z. Yang2014-11-151-49/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Instead of recording exposed-modules and reexported-modules as seperate fields in the installed package database, this commit merges them into a single field (exposed-modules). The motivation for this change is in preparation for the inclusion of *signatures* into the installed package database, which may also be reexported. Merging the representation means that we can treat reexports uniformly, no matter if they're a normal module or a signature. This commit adds a stub for signatures, but that code isn't wired up to anything yet. Contains Cabal submodule update to accommodate these changes. Signed-off-by: Edward Z.
