Here's another series of patches working towards being able to have a
Guile guix-daemon.

Most importantly I've taken what I think are the key changes from the
guile-daemon branch, and tweaked them based on my current thinking for
how to structure the code.

Additionally, there are some further changes to move functionality
(download-nar) out of the substitute script and in to the module. This
allows the Guile guix-daemon to work with substitutes directly, rather
than spawning the substitute script.

Also included are some smaller store changes, exporting some existing
things, adding a few new procedures and tweaking the database code.


Caleb Ristvedt (5):
  store: database: Register derivation outputs.
  gnu: linux-container: Make it more suitable for derivation-building.
  syscalls: Add missing pieces for derivation build environment.
  guix: store: environment: New module.
  store: build-derivations: New module.

Christopher Baines (18):
  store: Export protocol related constants.
  serialization: Export read-byte-string.
  store: Add text-output-path and text-output-path-from-hash.
  store: Add validate-store-name.
  store: database: Add procedures for querying valid paths.
  scripts: substitute: Untangle selecting fast vs small compressions.
  scripts: substitute: Extract script specific output from download-nar.
  syscalls: Add unshare.
  scripts: perform-download: Support configuring the %store-prefix.
  store: Export operation-id.
  store: database: Log when aborting transactions.
  store: database: Export transaction helpers.
  guix: http-client: Add network-error?.
  http-client: Include EPIPE in network-error?.
  scripts: substitute: Simplify with-timeout usage.
  scripts: substitute: Don't enforce cached connections in download-nar.
  substitutes: Move download-nar from substitutes script to here.
  substitutes: Add #:keep-alive? keyword argument to download-nar.
