* guix/inferior.scm (port->inferior): Bump protocol to (0 1 1).
(&inferior-exception)[stack]: New field.
(read-repl-response): Recognize 'exception' form for protocol (0 1 1).
* tests/inferior.scm ("&inferior-exception"): Check the value returned
by 'inferior-exception-stack'.
This avoids ambiguities when looking at a backtrace where the exception
was actually thrown by an inferior in a very different context.
* guix/inferior.scm (&inferior-exception): New condition type.
(read-repl-response): Add optional 'inferior' parameter. Raise
'&inferior-exception' instead of rethrowing to KEY when receiving an
'exception' message.
(read-inferior-response): Pass INFERIOR to 'read-repl-response'.
* tests/inferior.scm ("&inferior-exception"): New test.
This is a followup to 7a0836cffd.
* guix/scripts/package.scm: Adjust binding list of the (guix store roots)
autoload.
* guix/inferior.scm: Adjust binding list of the (guix cache) autoload.
* guix/inferior.scm (cached-channel-instance): Take an explicit 'store'
argument.
(inferior-for-channels): Wrap call to 'cached-channel-instance' in
'with-store'.
* guix/time-machine.scm (guix-time-machine): Wrap call to
'cached-channel-instance' in 'with-store'.

* guix/scripts/time-machine.scm: New file.
* Makefile.am: (MODULES): Add it.
* guix/scripts/pull.scm (channel-list): Export.
* guix/inferior.scm (cached-channel-instance): New procedure.
(inferior-for-channels): Use it.
* doc/guix.texi (Invoking guix time-machine): New section.
(Channels): Cross-reference it.

This makes the behaviour more consistent.
* guix/inferior.scm (inferior-pipe): Wrap the second open-pipe* call with
with-error-to-port, to match the first call to open-pipe*.
Previously, stderr for the inferior process would always be sent to /dev/null
because the current-output-port when the process is launched is a void
port. This change means that it's possible to pass in a different port to use.
* guix/inferior.scm (inferior-pipe): Take the error-port as an argument.
(open-inferior): Add new error-port keyword argument, with a default
of (%make-void-port "w").
Rather than (guix scripts repl), from which the machine-repl procedure was
removed in [1].
1: 92a4087bf4
* guix/inferior.scm (inferior-pipe): Load (guix repl) rather than (guix
scripts repl).
Until now '&store-protocol-error' conditions raised in the inferior
would not be correctly propagated because SRFI-35 records lack a read
syntax.

by Carl Dong <contact@carldong.me>.
* guix/inferior.scm (port->inferior): Import (srfi srfi-34) in the inferior.
(inferior-eval-with-store): Define 'error?' and 'error-message'. Wrap
call to PROC in 'guard'. Check the response of INFERIOR for a
'store-protocol-error' or a 'result' tag.
* tests/inferior.scm ("inferior-eval-with-store, &store-protocol-error"):
New test.
Fixes <https://bugs.gnu.org/34637>.
Reported by Martin Flack <martin.flack@gmail.com>.
Previously we'd fail to build the package cache for old versions of Guix
that lack 'guix repl'. Now we simply ignore the issue and keep going
without a cache.
* guix/inferior.scm (gexp->derivation-in-inferior): Add
#:silent-failure? and honor it.
[drop-extra-keyword]: New procedure.
Use it.
* guix/channels.scm (package-cache-file): Pass #:silent-failure? #t.
Previously the imported modules and extensions of EXP would be missing
from the load path of 'guix repl'.
* guix/inferior.scm (gexp->derivation-in-inferior)[script]: New
variable.
[trampoline]: Write (primitive-load #$script) to PIPE. Add #$output.
* tests/channels.scm ("channel-instances->manifest")[depends?]: Check
for requisites rather than direct references.
Adjust callers accordingly.
* guix/inferior.scm (inferior-eval-with-store): New procedure, with code
formerly in 'inferior-package-derivation'.
(inferior-package-derivation): Rewrite in terms of
'inferior-eval-with-store'.
* tests/inferior.scm ("inferior-eval-with-store"): New test.
* guix/inferior.scm (inferior-package->manifest-entry): New procedure.
* tests/inferior.scm (manifest-entry->list): New procedure.
("inferior-package->manifest-entry"): New test.
* guix/inferior.scm (<inferior>)[packages, table]: New fields.
(open-inferior): Initialize these new fields.
(inferior-packages): Rename to...
(%inferior-packages): ... this.
(inferior-packages): New procedure; force the promise.
(%inferior-package-table, lookup-inferior-packages): New procedures.
* tests/inferior.scm ("lookup-inferior-packages")
("lookup-inferior-packages and eq?-ness"): New tests.
* guix/inferior.scm (read-inferior-response)
(send-inferior-request): New procedures.
(inferior-eval): Rewrite in terms of these.
(proxy, inferior-package-derivation, inferior-package->derivation)
(package-compiler): New procedures.
* tests/inferior.scm ("inferior-package-derivation"): New test.
