Fri Aug 28 16:37:04 PDT 2009 Duncan Coutts <duncan(a)haskell.org> * Use -R flags for hsc2hs wherever we use -L flags on ELF platforms. Ignore-this: 357aa0d1865a1fe6bf37fb6f41e2c93a This fixes use of hsc2hs in cases where things like libgmp is not on the system's dynamic linker path. It's ok to use rpath in the case of hsc2hs because the linked programs are run immediately and never installed.

new hackage-server testing host
by Duncan Coutts 28 Aug '09

28 Aug '09

Hi Ross, (and other people interested in the hackage server) I've got ports 80 and 8080 open on the community sparc server and will be using it as a host for testing the new hackage-server implementation. http://sparky.haskell.org:8080/ One thing I noticed when importing data into it is that there are a small handful of packages that have no entry in the upload log. The new server expects to find such an entry so that it knows when the package was added. Ross, the packages in question I think are the ones that you uploaded after ghc-6.10 was released including base, containers etc. I'm guessing that the normal hackage upload rejected them with some QA complaints and that you had to add them by a manual process. I'm hoping we can just fix the upload log data by appending the appropriate lines to the upload log, eg by doing: echo 'Thu Apr 9 16:25:43 UTC 2009 RossPaterson base 4.1.0.0' >> log Does that seem reasonable? It means those lines would be out of order chronologically, but I don't think that is important. If you think this is reasonable then I'll get you the proper checked list of missing uploads. The other alternative might be for the current hackage server to let us download a tarball of all the package meta-data including the tag files, and we could adapt the new hackage-server to import from that format. Hopefully though we only need to take this approach if we start making much more use of the tag files. Duncan

patch applied (cabal-install): Fix calculation of paths in check for bindir symlink overwriting

Fri Aug 28 17:49:59 PDT 2009 Duncan Coutts <duncan(a)haskell.org> * Fix calculation of paths in check for bindir symlink overwriting Ignore-this: d4dd8e12c03d23ce935de94cedbda257 We were doing it wrong, but Linux realpath() C function was letting us get away with it. The Solaris realpath() is stricter. The new implementation is also simpler, relying on the fact that the canonicalizePath function will resolve symlinks.

[Hackage] #577: an executable and library differing in capitalization use the same build dir on case-insensitive filesystems

patch applied (cabal): Add the ABI hash to the InstalledPackageId for inplace registrations too
by Simon Marlow 26 Aug '09

26 Aug '09

Wed Aug 26 08:51:57 PDT 2009 Simon Marlow <marlowsd(a)gmail.com> * Add the ABI hash to the InstalledPackageId for inplace registrations too Ignore-this: f10a1e90492a356a8ed8ed78fd056176 Previously, we just added a -inplace suffix, but this will cause problems when developing multiple packages inplace, and then installing them. Also, there was a round of refactoring: registerPackage now takes the InstalledPackageId as an argument, and generateRegistrationInfo is exposed for constructing it. This means that callers of registerPackage get to munge the InstalledPackageInfo before it is registered.

patch applied (cabal): Change finalizePackageDescription to take dep test function

This insulates us from the representation of the installed package set which is good since we now have several representations. It also opens the door to generalising the kinds of constraints we can handle.

[Hackage] #274: Add a 'build from sdist tarball' feature
by Hackage 23 Aug '09

23 Aug '09

#274: Add a 'build from sdist tarball' feature ----------------------------+----------------------------------------------- Reporter: guest | Owner: Type: enhancement | Status: new Priority: low | Milestone: Component: Cabal library | Version: 1.2.3.0 Severity: normal | Keywords: Difficulty: normal | Ghcversion: 6.8.2 Platform: | ----------------------------+----------------------------------------------- I've often seen Darcs repos where the sdist tarball was incomplete, or where a person had a tarball which was incomplete. I think this is because most people just never use the tarball; if they do ever use it, it's because it's what was downloaded from Hackage. The reason is that doing so is much more complex than 'configure; build; install': you need to configure, create an sdist tarball, cd into dist/; do a tar -xvf or whatever of the correct tarball; cd into *that* - and then you can configure/build/install. Assuming it is a working tarball. Now, of course you can automate it. After the first dozen times, I wrote myself a shellscript to do all that for me: function build_sdist { clean_configure && sdist && cd dist/ && untar *.tar.gz && cd `ls -t ./ | grep "/" | head -n 1` && clean_configure && build && hinstall; haddock && hinstall; } (This is pretty long and imperfect, but it would be even longer if all the other aliases and function definitions were included; I think they're pretty straightforwardly named though, so I haven't included them.) It seems to me that this would be, at the very least, a useful adjunct to cabal check - if it makes sense to see whether various fields are filled out sanely, surely it makes sense to see whether needed files are included/listed? It might be even better to make the normal 'runhaskell Setup build' do it from sdist, but this is harder to code (besides the forgoing, you'd need to copy in the configuration from the top-level, from when the user ran 'runhaskell Setup configure' and added whatever options) and possibly more confusing ("But Foo.hs *is* there, right there in src/! Why can't Cabal find it?"). So I'd be satisfied to do something like 'cabal checkdist'. -- gwern -- Ticket URL: <http://hackage.haskell.org/trac/hackage/ticket/274> Hackage <http://haskell.org/cabal/> Hackage: Cabal and related projects
