Ideally, extend .nix-cache-info to include the server's public key, and also reply to requests for .narinfo.sig. Optionally, use Guile-Avahi to publish the service. * MAYBE Add a substituter that uses the GNUnet DHT or [[http://libswift.org][libswift]] Would be neat if binaries could be pushed to and pulled from the GNUnet DHT or rather libswift (since DHTs aren’t suited for large payloads). Guix users would sign their binaries, and define which binaries they trust. Use UPnP and similar to traverse NAT, like ‘filegive’ does. * user interface ** add guile-ncurses interface * extend ** add ‘recommends’ field For instance, glibc, binutils, gcc, and ld-wrapper would recommend each other. ‘guix package -i’ could ask interactively (?), or allow users to follow all or none of the recommendations. ** add a ‘user-environment-hook’ This should specify builder code to be run when building a user environment with ‘guix-package’. For instance, Texinfo’s hook would create a new ‘dir’. ** extend ‘propagated-build-inputs’ with support for multiple outputs #+BEGIN_SRC scheme (outputs '("out" "include")) (propagated-build-inputs `(((("i1" ,p1 "o1") ("i2" ,p2)) => "include") ("i3" ,p3))) #+END_SRC * synchronize non-GNU package descriptions with the [[http://directory.fsf.org][FSD]] Meta-data for GNU packages, including descriptions and synopses, can be dumped from the FSD: http://directory.fsf.org/wiki?title=GNU/Export&action=purge . We could periodically synchronize with that. * add a guildhall build system The Guildhall is Guile’s packaging system. It should be easy to add a ‘guildhall-build-system’ that does the right thing based on guildhall recipes. * union Support sophisticated collision handling when building a union: honor per-package priorities, etc. * add GUIX_ALLOW_EXPENSIVE_TESTS Tests that need to download stuff or otherwise take a long time would only be run when that is defined. * add "guix challenge" Would download a substitute, and compare its contents against a (hopefully locally-built) copy. * guix build utils ** MAYBE Change ‘ld-wrapper’ to add RPATH for libs passed by file name ** MAYBE Add equivalent to chrpath that uses [[https://gitorious.org/guile-dlhacks/guile-dlhacks/][guile-dlhacks]] ** MAYBE Add a hash-rewriting thing for deep dependency replacement without rebuild See [[https://github.com/NixOS/nixpkgs/commit/d1662d715514e6ef9d3dc29f132f1b3d8e608a18][Shea Levy's `replace-dependency' in Nixpkgs]]. * distro ** port to GNU/Hurd, aka. ‘i686-gnu’ Problems include that current glibc releases do not build on GNU/Hurd. In addition, there haven’t been stable releases of GNU Mach, MiG, and Hurd, which would be a pre-condition. CAN_LINK_SYMLINK definition. * guix/store/deduplication.scm (%deduplication-minimum-size): New variable. (deduplicate)[loop]: Do not recurse when FILE's size is below %DEDUPLICATION-MINIMUM-SIZE. (dump-port): New procedure. (dump-file/deduplicate)[hash]: Turn into... [dump-and-compute-hash]: ... this thunk. Call 'deduplicate' only when SIZE is greater than %DEDUPLICATION-MINIMUM-SIZE; otherwise call 'dump-port'. * nix/libstore/gc.cc (LocalStore::removeUnusedLinks): Drop files where st.st_size < deduplicationMinSize. * nix/libstore/local-store.hh (deduplicationMinSize): New declaration. * nix/libstore/optimise-store.cc (deduplicationMinSize): New variable. (LocalStore::optimisePath_): Return when PATH is a symlink or smaller than 'deduplicationMinSize'. * tests/derivations.scm ("identical files are deduplicated"): Produce files bigger than %DEDUPLICATION-MINIMUM-SIZE. * tests/nar.scm ("restore-file-set with directories (signed, valid)"): Likewise. * tests/store-deduplication.scm ("deduplicate, below %deduplication-minimum-size"): New test. ("deduplicate", "deduplicate, ENOSPC"): Produce files bigger than %DEDUPLICATION-MINIMUM-SIZE. * tests/store.scm ("substitute, deduplication"): Likewise.
