* guix/ui.scm (fill-paragraph, string->recutils, package->recutils): New
procedures.
* guix-package.in (guix-package)[process-query]: Use `package->recutils'
to display package meta-data.
* tests/guix-package.sh: Adjust test.
* tests/ui.scm: New file.
* Makefile.am (TESTS): Add it.
* doc/guix.texi (Invoking guix-package): Adjust `--search'
documentation, and give an example.
* guix/derivations.scm (read-derivation): Rename to...
(%read-derivation): ... this.
(read-derivation): New procedure.
This reduces the execution of "guix-build gdb" from 2.5s to 1.7s.
* guix/store.scm (open-connection): Call `make-hash-table' with 100.
(add-text-to-store): Move TEXT first in ARGS, for better `hash'
results.
(add-to-store): Likewise, move ST first.
* guix/store.scm (add-to-store): Remove the `fixed?' parameter from the
public interface.
* gnu/packages/bootstrap.scm, guix-download.in, guix/derivations.scm,
guix/packages.scm, tests/derivations.scm: Update all callers
accordingly.
* guix/store.scm (operation): New macro.
(define-operation): Define in terms of `operation'.
(add-text-to-store): Define using `operation', and remove now
unnecessary `set!'.
(add-to-store): Likewise.
(add-text-to-store/cached, add-to-store/cached): Remove.
* guix/store.scm (write-string): Optimize to write the length, contents,
and padding all at once. This yields a 2% improvement on the
execution time of "guix-build gdb".
* guix/ui.scm (install-locale): New procedure.
* guix-build.in, guix-download.in, guix-gc.in, guix-import.in,
guix-package.in: Use it instead of (setlocale LC_ALL "").
* guix/store.scm (<nix-server>)[atts-cache]: New field.
(add-text-to-store/cached): New procedure. Use it as a wrapper around
`add-text-to-store'.
When running "guix-build gdb", this reduces the number of RPCs from
3048 to 289, and execution time from 4.7s to 2.6s.
* guix/store.scm (<nix-server>)[ats-cache]: New field.
(open-connection): Update accordingly.
(add-to-store/cached): Use (nix-server-add-to-store-cache SERVER)
instead of a weak hash table.
* guix/store.scm (add-to-store/cached): New variable.
Use it as the new `add-to-store'.
This reduces the number of RPCs when doing "guix-build gdb" from 5009
to 3053, and the execution time from 7s to 3.9s.

<http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00325.html>.
* guix-package.in (latest-profile-number): Remove.
(switch-symlinks): New procedure.
(roll-back)[switch-link]: Use it.
(guix-package)[process-actions]: Always choose NUMBER + 1 for the new
profile. Use `switch-symlinks' instead of `symlink'. Remove code to
delete PROFILE when it exists since `switch-symlinks' has the same
effect.
* tests/guix-package.sh: Adjust existing `--roll-back' tests.
* doc/guix.texi (Invoking guix-package): Document this `--roll-back'
behavior.
Suggested by Andreas Enge <andreas@enge.fr> at
<http://lists.gnu.org/archive/html/bug-guix/2013-01/msg00316.html>.
* guix-package.in (roll-back): Check whether PROFILE is valid using
`file-exists?'. When NUMBER is zero, just emit a notice. When
PREVIOUS-NUMBER is zero and PREVIOUS-PROFILE does not exist, build the
empty profile, and link to it.
* tests/guix-package.sh: Add tests.
* doc/guix.texi (Invoking guix-package): Document the new behavior.
