-* integrate needed Nix code
-
-** Remove dependency on OpenSSL
-
-The ‘openssl’ command-line tool is used in libstore to sign store paths
-to be exported, and to check such signatures. The signing keys are
-usually in /etc/nix/signing-key.{pub,sec}. They are a PKCS#8-encoded
-X.509 SubjectPublicKeyInfo. These can be decoded with the [[http://lists.gnu.org/archive/html/help-gnutls/2012-12/msg00012.html][C API of
-GnuTLS]], but not yet with its Guile bindings. There’s also
-‘gnutls_privkey_sign_data’ to sign, and related functions.
-
-
-** Add `guix publish' to publish the store using Guile's web server
+* Add `guix publish' to publish the store using Guile's web server
Generate narinfos and nars on the fly, upon HTTP GET requests.
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]]
+* 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
Use UPnP and similar to traverse NAT, like ‘filegive’ does.
-** Add a remote build hook
-
-Like scripts/build-remote.pl in Nix.
-
* user interface
-** Add a package.el (Emacs) back-end
-
-package.el is quite monolithic, but we may be able to reuse/extend
-‘package-menu-mode’ or at least ‘tabulated-list-mode’.
-
** add guile-ncurses interface
-* extend <origin>
-** add OpenPGP signatures:
-
- (origin
- (method http-fetch)
- (uri "http://.../foo.tgz")
- (signature-uri (string-append uri ".sig"))
- (signer-openpgp-fingerprint "..."))
-
-** allow <origin> to be a derivation/package or a file
-
* extend <package>
-
** add ‘recommends’ field
For instance, glibc, binutils, gcc, and ld-wrapper would recommend each other.
environment with ‘guix-package’. For instance, Texinfo’s hook would
create a new ‘dir’.
-** add ‘patches’ there
-
** extend ‘propagated-build-inputs’ with support for multiple outputs
#+BEGIN_SRC scheme
("i3" ,p3)))
#+END_SRC
-
-* synchronize package descriptions with GSRC and/or the [[http://directory.fsf.org][FSD]]
+* 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.
-See http://lists.gnu.org/archive/html/bug-guix/2013-04/msg00120.html for info
-on how to synchronize with GSRC's descriptions.
-
* 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.
-* build-expression->derivation: define `%system' in the builder
-
-Would allow build expressions to have system-dependent code, like
-`glibc-dynamic-linker'.
-
-* add ‘allowed-references’ in <package>
-
-[[file:~/src/nix/src/libstore/build.cc::if%20(drv.env.find("allowedReferences")%20!%3D%20drv.env.end())%20{][See how Nix implements that internally]].
-
* union
-Support sophisticated collision handling when building a union: check
-whether the colliding files are identical, honor per-package priorities,
-etc.
+Support sophisticated collision handling when building a union: honor
+per-package priorities, etc.
* add GUIX_ALLOW_EXPENSIVE_TESTS
Would download a substitute, and compare its contents against a (hopefully
locally-built) copy.
-* guix package
-
-** add ‘--list-generations’, and ‘--delete-generations’
-
* guix build utils
** MAYBE Change ‘ld-wrapper’ to add RPATH for libs passed by file name
See [[https://github.com/NixOS/nixpkgs/commit/d1662d715514e6ef9d3dc29f132f1b3d8e608a18][Shea Levy's `replace-dependency' in Nixpkgs]].
* distro
-** port to new GNU/Linux platforms, notably ‘mipsel64-linux’
** 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.
-** make a bootable GNU/Linux-Libre distro, with OS configuration EDSL
-
-Similar in spirit to /etc/nixos/configuration.nix.
