[Hackage] #802: copy command should not overwrite files

#802: copy command should not overwrite files ----------------------------+----------------------------------------------- Reporter: duncan | Owner: Type: defect | Status: new Priority: normal | Milestone: Component: Cabal library | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- see http://hackage.haskell.org/trac/ghc/ticket/4955 Cabal can inadvertently get users into situations where they have registered packages that do not match their package registration information. Consider the package darcs and darcs-fastconvert which depends on the darcs library. If one installs darcs, then later in the darcs build tree do a `cabal copy` then it will overwrite the library .hi files but not update the library registration. This will mean that subsequent builds of darcs-fastconvert will fail with very confusing error messages (see the ghc ticket above). A similar thing could happen with inplace registrations. The suggestion to avoid this problem is for `cabal copy` to refuse to overwrite .hi files (executables are fine). This is also partly related to #645 because some people are using `cabal copy` to avoid having to use `cabal install` which spends too long reconfiguring and checking nothing needs building before actually installing. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/802> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#787: --test-option should support template argument ----------------------------------+----------------------------------------- Reporter: tibbe | Owner: Type: enhancement | Status: new Priority: normal | Milestone: Component: cabal-install tool | Version: HEAD Severity: normal | Keywords: Difficulty: very easy (<1 hour) | Ghcversion: Platform: | ----------------------------------+----------------------------------------- The test-framework package can optionally output JUnit XML, an XML flavor understood by many continuous build systems, if you pass it the `--jxml` flag. Using that flag, one can get `cabal test` to output JUnit XML: {{{ cabal configure --enable-tests cabal build cabal test --test-option=--jxml=dist/test/junit.xml }}} However, the `--test-option` flag doesn't allow the user to pass different flags to different test executables so each test executable will override the output of the previous. If the `--test-option` flag took a name template argument, supporting a `$test-suite` placeholder, you could generate one JUnit XML file per test suite: {{{ cabal configure --enable-tests cabal build cabal test --test-option=--jxml=dist/test/$test-suite.xml }}} The detailed test interface might support this in some nicer way, but this is a cheap way to have Cabal cooperate better with other test runners. -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/787> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

It's quite a lot of connections to Hackage to download every single file, it takes quite a lot of time to download them individually (about 50 minutes using wget serially), and the tarball on Hoogle is often (always?) out of date. Would it be possible for Hackage to supply a tarball of all the Hoogle input files? -- Neil Mitchell (Hoogle author) -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/779> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects

#792: sdist doesn't not include source files from test-suite stanzas ----------------------------+----------------------------------------------- Reporter: tibbe | Owner: ttuegel Type: defect | Status: new Priority: normal | Milestone: Cabal-1.10 Component: Cabal library | Version: 1.8.0.6 Severity: normal | Keywords: Difficulty: unknown | Ghcversion: Platform: | ----------------------------+----------------------------------------------- `cabal sdist` doesn't include the source files from test-suite stanzas when generating the tarball. This leads to Hackage's QA checks rejecting the package. Steps to reproduce: 1. Create a Cabal package with a test-suite stanza (and set `hs-source- dirs` to e.g. `tests`). 2. Run `cabal sdist` 3. Unpack the tarball and look at the content.
