This fixes a bug whereby `read-response' would read more than just the
response, with the extra data going into the port's buffer; the

"bzip2: (stdin) is not a bzip2 file."
* guix/utils.scm (filtered-port): Document that INPUT must be
unbuffered.

* 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.
