<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.
* guix/packages.scm (<package>)[inputs]: Mark as thunked.
(package-derivation)[expand-input]: Remove case where the input is a
procedure.
* tests/packages.scm ("trivial with system-dependent input"): Remove
`lambda', and use (%current-system).
* gnu/packages/bootstrap.scm (package-from-tarball): Likewise for `inputs'.
(%bootstrap-glibc, %bootstrap-gcc): Likewise.
* gnu/packages/scheme.scm (mit-scheme): Likewise.
* guix-package.in (guix-package)[parse-options]: Call `leave' when
passed a non-option argument.
Reported by Andreas Enge <andreas@enge.fr>.
* tests/guix-package.sh: Add test.
* guix/utils.scm (define-record-type*)[make-syntactic-constructor]: Add
a `thunked' parameter.
(thunked-field?, field-bindings): New procedures. Use the latter when
generating `letrec*' bindings.
[thunked-field?, thunked-field-accessor-name, field-spec->srfi-9,
thunked-field-accessor-name]: New procedures.
Use them when generating the `define-record-type' form, and to
generated thunk field accessors, along call to
`make-syntactic-constructor' with the new argument.
* tests/utils.scm ("define-record-type* & thunked",
"define-record-type* & thunked & default",
"define-record-type* & thunked & inherited"): New tests.
* guix-package.in (roll-back): Fix file name of PREVIOUS-PROFILE, which
could end up containing the dirname twice.
Reported by Nikita and Andreas.
* tests/guix-package.sh: Add test.
* guix-build.in (guix-build)[find-package]: New procedure.
Use it instead of using `find-packages-by-name' directly.
Suggested by Andreas Enge <andreas@enge.fr>.
* tests/guix-build.sh: Add tests.
* doc/guix.texi (Invoking guix-build): Add `coreutils-8.20' as an
example. Fix guile-1.8 example.
* guix/packages.scm (cache): Change the `drv' argument to `thunk'.
Memoize all the return values of THUNK.
(cached-derivation): Remove.
(cached): New macro.
(package-derivation): Use `cached' instead of `(or (cached-derivation) …)'.
* doc/guix.texi (Defining Packages): Update accordingly.
* guix-package.in (profile-numbers): New procedure.
(latest-profile-number): Use it.
(previous-profile-number): New procedure.
(roll-back): Use it lieu of `1-'. Check whether PREVIOUS-NUMBER is
zero, and raise an error when it is.
* tests/guix-package.sh: Test whether we can roll back over a "hole".
Based on a patch by Nikita Karetnikov <nikita@karetnikov.org>.
* guix-package.in (profile-regexp): New procedure.
(latest-profile-number): Remove `%profile-rx', and use
`profile-regexp' instead.
(profile-number, roll-back): New procedure.
(show-help): Add `--roll-back'.
(%options): Likewise.
(guix-package)[process-actions]: First check whether `roll-back?' is
among OPTS, and call `roll-back' if it is, followed by a recursive
call to `process-actions'. Emit the "nothing to be done" message only
when INSTALL or REMOVE is non-empty.
* tests/guix-package.sh (readlink_base): New function.
Add tests for `--roll-back'.
* doc/guix.texi (Invoking guix-package): Document `--roll-back'.
Reported by Andreas Enge.
* guix-package.in (%profile-directory): Honor $NIX_STATE_DIR.
(guix-package)[ensure-default-profile]: Use it.
[process-actions]: Call it when the `profile' option is
%CURRENT-PROFILE.
* tests/guix-package.sh: Add installation test with $HOME set, using the
default profile.
* guix/build/union.scm (delete-duplicate-leaves): New procedure.
(union-build)[leaf=?, resolve-collision]: New procedures.
Use `delete-duplicate-leaves' on the result of `tree-union'.
* tests/union.scm ("delete-duplicate-leaves, default",
"delete-duplicate-leaves, file names"): New tests.
Before it would list inputs not built, even if the outputs of the given
derivation were already available.
* guix/derivations.scm (derivation-prerequisites-to-build): Add
`outputs' keyword parameter.
[built?, derivation-built?]: New procedures.
[loop]: Add `sub-drvs' parameter. Use `derivation-built?' to check if
the SUB-DRVS of DRV are built before checking its inputs.
* guix-package.in (%options): Remove #\b as an alternate for
"bootstrap".
(show-help): Adjust accordingly.
* tests/guix-package.sh: Use `--bootstrap' instead of `-b'.
* tests/derivations.scm (%bash): New variable.
Replace occurrences of "/bin/sh" by %BASH.
* tests/union.scm ("union-build"): Delete duplicates from
%BOOTSTRAP-INPUTS.
* tests/builders.scm (network-reachable?): New variable.

(%have-nix-hash?): New variable. Update `test-skip' clause to use it.
* guix-package.in (guix-package)[process-actions]: Compute PACKAGES such
that packages listed in INSTALL* are first removed from the remainder
of the list. When PROF is equal to the previous profile's store path,
do nothing. Reported by Andreas Enge <andreas@enge.fr>.
* tests/guix-package.sh: Test the behavior of installing the same store
path twice. When removing a package, omit its version number.
* guix/store.scm (gc-action): New enumerate type.
(read-long-long, read-string-list, write-store-path,
write-store-path-list, read-store-path-list): New procedures.
(write-arg): Add support for `store-path' and `store-path-list'.
(read-arg): Add support for `store-path-list'.
(define-operation): Add support for multiple-value returns.
(run-gc, live-paths, dead-paths, collect-garbage, delete-paths): New
procedures.

* Makefile.am (TESTS): Add it.
* test-env.in: New file.
* configure.ac: Add it to `AC_CONFIG_FILES' and `commands-exec'.
* config-daemon.ac: Set and substitute `GUIX_TEST_ROOT'.
* Makefile.am (SCM_LOG_COMPILER, SH_LOG_COMPILER): Use it in lieu of
`pre-inst-env'.
* daemon.am (test_root): Remove
(AM_TESTS_ENVIRONMENT): Remove `TEST_ROOT'.
(clean-local): Use $(GUIX_TEST_ROOT); make files writable before
removing them.guix_test_root
* tests/guix-daemon.sh: Remove `NIX_' variable settings; don't launch
`guix-daemon'.
* nix/scripts/list-runtime-roots.in: New file.
* config-daemon.ac: Add `AC_CONFIG_FILES' invocation for it.
* daemon.am (nodist_pkglibexec_SCRIPTS): New variable.
(AM_TESTS_ENVIRONMENT): Define `top_builddir'.
* tests/guix-daemon.sh: Export `NIX_ROOT_FINDER'.
* nix/sync-with-upstream: Substitute the path to the root finder in
libstore/gc.cc.
* guix/derivations.scm (derivation)[inputs]: Fix typo in call to
`add-to-store'.
* tests/derivations.scm ("derivation with local file as input"): New test.
* tests/packages.scm ("trivial with local file as input"): New test.
* distro.scm (fold-packages): New procedure.
(find-packages-by-name): Use it instead of hand-written traversal;
remove `package?' checks from `right-package?'.
* tests/packages.scm ("fold-packages"): New test.
* guix-download.in (http-fetch, ftp-fetch): Remove.
(fetch-and-store): Replace `uri' parameter with `name', for the output
file name. Redirect the output of `fetch' to the error port.
(guix-download): Call `url-fetch' for all URI schemes except `file'.
Handle PATH equal to #f.
* guix/download.scm: Export `%mirrors'.
* tests/guix-download.sh: Change erroneous URL, because URLs at
example.com are all valid redirections.
* guix-download.in (fetch-and-store): New procedure.
(guix-download): Use it to compute PATH. Call `add-to-store' when
a `file' URI scheme is used.
* Makefile.am (AM_TESTS_ENVIRONMENT): New variable.
* tests/guix-download.sh: Add test.
* guix-download.in (guix-download): Error out when `string->uri'
returns #f. Use `leave' when the scheme is unknown.
* tests/guix-download.sh: Add tests.
* tests/derivations.scm ("build-expression->derivation for fixed-output
derivation"): Remove test. It is redundant with that in builders.scm,
and doesn't work out of the box with the statically-linked
%BOOTSTRAP-GUILE.
