Hi, Is there any way to query the latest version of a particular package stored on Hackage, that was successfully built? I mean, not _how_ to do that (I have some ideas that I have to download directory listings, looking for failure logs, etc.), but is there any tool or interface already available that does similar things? Unfortunately, tarfiles provided on Hackage (like 00-index.tar.gz) do not help, e. g. BerkeleyDB failed to build in all three versions, yet its all cabal files are included in the tarball: tar tvf 00-index.tar.gz ... -rw-r--r-- www-data/www-data 1055 2007-04-06 13:03 ./BerkeleyDB/0.1/BerkeleyDB.cabal -rw-r--r-- www-data/www-data 1061 2007-04-06 16:59 ./BerkeleyDB/0.2/BerkeleyDB.cabal -rw-rw-r-- www-data/www-data 1236 2008-01-11 14:42 ./BerkeleyDB/0.3/BerkeleyDB.cabal I remember, in the past, HackageDB was expected to become a database of some sort: is there any database-like backend that would accept queries, other than just parsing Apache dir listings? My final goal, given some master-list of package names, to be able to retrieve latest succesfully built (not just uploaded) releases from Hackage Thanks. -- Dimitry Golubovsky Anywhere on the Web

It is certainly part of the plan. There is currently no convenient way to get at the information. I've been working on the client side of things, actually generating decent build reports. That step is now done and it's included in cabal-install-0.5.0. The next step is letting people upload build reports to hackage and collating the data and extracting useful information from the data. Included in that would be some way for external clients to get at the data and summaries both via human readable info on the package page and something machine readable.

In the mean time, using the current system, you can get at stuff by knowing what urls to look at. eg: http://hackage.haskell.org/packages/archive/pureMD5/0.2.0/logs/failure/ghc-6... So most recent packages have a logs subdir and either a success or failure dir with a log file for a particular version of ghc, which at the moment is 6.6 or 6.8.
Unfortunately, tarfiles provided on Hackage (like 00-index.tar.gz) do not help, e. g. BerkeleyDB failed to build in all three versions, yet its all cabal files are included in the tarball:
Yes, the archive is complete. We do not remove anything. In future we may augment the index with extra meta-data on what works, what is obsolete or what is recommended. Duncan
