Description of problem: gen_contents_index takes upwards of 20s to regenerate haddock doc indices and is run after every ghc-*-devel package rpm transaction, which slows down installation, updates, and removal of haskell libraries significantly. Version-Release number of selected component (if applicable): ghc-6.12.3 How reproducible: every time Steps to Reproduce: # cd %{ghcdocbasedir}/libraries # time ./gen_contents_index Actual results: On a typical machine with most ghc-*-devel installed it takes about 25-30s to run. Expected results: 20-30s wait for script of rpm transaction is unacceptable. Additional info: Re-indexing could be moved to a cronjob perhaps (daily or hourly). Maybe only concern would be to avoid re-indexing while do ghc-*-devel rpm transactions, but perhaps the chance of collision is low enough not to worry specially if we run hourly. (If there are no changes it can be a no-op there should not be much system impact even hourly.) I am going to check if ghc-6.12.1 is affected too.
I suspect the overriding issue is probably memory pressure, but a "workaround" seems to be to remove ghc-type-level-devel (or ghc-type-level-doc on older releases). I will push an ghc update for F14 that makes gen_contents_index ignore type-level. But for F15 I think we should go with the cronjob.
