This avoids the script crashing if all data is fetched from the cache.
* guix/scripts/weather.scm (report-server-coverage): Only show request
statistics when some requests have been made.
Previously, the "seconds per request" and "requests per second" statistics
really reported (cache lookups + requests) per second. By looking at the
actual number of requests made within lookup-narinfos, a more representative
value can be reported.
* guix/scripts/weather.scm (let/time): Allow for multiple return values.
(report-server-coverage): Alter the reporting of request statistics.
The call-with-connection-error-handling was added in
20c08a8a45, but that error handling was
previously inside of open-connection-for-uri/maybe, which is related
to (call-)with-cached-connection which was used in process-substitution, but
only actually used with call-with-cached-connection when used in
fetch-narinfos.
There's some handling for similar errors within with-networking, which is used
within process-substitution.
* guix/scripts/substitute.scm (process-substitution): Remove
call-with-connection-error-handling call.
In f50f5751ff, the way fetch was called within
process-substitution was changed. As call-with-cached-connection actually
includes important error handling for the opening of a HTTP request, this
change removed some error handling. This commit adds that back.
Fixes <https://bugs.gnu.org/47157>.
* guix/scripts/substitute.scm (call-with-cached-connection): New procedure.
(with-cached-connection): New syntax rule.
(process-substitution): Retry once for some errors when making HTTP requests
to fetch substitutes.
Break cached-channel-instance into two different procedures:
channels->cached-profile and instances->cached-profile operating respectively
on channels and channels instances.
* guix/inferior.scm (cached-channel-instance): Rename it into ...
(cached-profile): ... this new procedure.
(channels->cached-profile, instances->cached-profile): New procedures.
* guix/scripts/time-machine.scm (guix-time-machine): Adapt accordingly.
This means there's a useful progress bar when running guix weather.
* guix/scripts/weather.scm (report-server-coverage): Pass
#:make-progress-reporter to lookup-narinfos.
Rather than always outputting to (current-error-port) in
lookup-narinfos (which is called from within lookup-narinfos/diverse), take a
procedure which should return a progress reporter, and defer any output to
that.
As this is now general purpose code, make the default behaviour to output
nothing. Maintain the current behaviour of the substitute script by moving the
progress reporter implementation there, and passing it in when calling
lookup-narinfos/diverse.
These changes should be generally useful, but I'm particularly looking at
getting guix weather to do progress reporting differently, with this new
flexibility.
* guix/substitutes.scm (fetch-narinfos): Take a procedure to make a
progress-reporter, and use that rather than the hardcoded behaviour.
(lookup-narinfos): Add #:make-progress-reporter keyword argument, and pass
this through to fetch-narinfos.
(lookup-narinfos/diverse): Add a #:make-progress-reporter keyword argument,
and pass this through to lookup-narinfos.
* guix/scripts/substitute.scm (process-query): Pass a progress-reporter to
lookup-narinfos/diverse.
Fixes <https://bugs.gnu.org/38884>.
* guix/scripts/system.scm (switch-to-system-generation): Load the
activate script for that generation.
squash! scripts: system: Activate system when switching generations.
This means there's a module for working with substitutes, rather than all the
code sitting in the script. The need for this can be seen with the weather and
challenge scripts, that now don't have to use code from the substitute script,
but can instead use the substitute module.
The separation here between the actual functionality of the substitute script
and the underlying functionality used both there and elsewhere should make
maintenance easier moving forward.
This commit just moves code, none of the code should have been changed
significantly.
* guix/scripts/substitute.scm (%narinfo-cache-directory, %narinfo-ttl,
%narinfo-negative-ttl, %narinfo-transient-error-ttl, %unreachable-hosts): Move
variables to guix/substitutes.scm.
(narinfo-cache-file, cached-narinfo, cache-narinfo!, narinfo-request,
read-to-eof, call-with-connection-error-handling, fetch-narinfos,
lookup-narinfos, lookup-narinfos/diverse): Move procedures to
guix/substitutes.scm.
* guix/substitutes.scm: New file.
* Makefile.am: Add it.
* guix/narinfo.scm: Remove redundant module.
* guix/scripts/challenge.scm: Change (guix scripts substitute) to (guix
substitutes).
* guix/scripts/weather.scm: Change (guix scripts substitute) to (guix
substitutes).
Previously, transformations applied from a manifest (rather than via
"guix install") would be lost. This change fixes that and simplifies
things.

Fixes <https://bugs.gnu.org/46362>.
Reported by Zhu Zihao <all_but_last@163.com>.
Previously, backtraces due to uncaught exceptions would always to go
file descriptor 2; the daemon would read it and error out with something
like:
error: got unexpected path `Backtrace:' from substituter
This patch fixes that by ensuring backtraces are properly displayed on
file descriptor 4.
* guix/scripts/substitute.scm (with-redirected-error-port): New macro.
(guix-substitute): Use 'with-redirected-error-port' instead of 'parameterize'.
This is part of trying to reduce the interdependency of code within the
substitute module.
This commit addresses some of the error handling that was performed through
open-connection-for-uri/maybe. The new approach is to use
call-with-connection-error-handling, and wrap calls to http-multiple-get and
http-fetch with that procedure, which takes care of handling connection
errors.
I think this is even slightly more rigerous than the previous setup, because
this approach handles connection errors that occur when http-multiple-get
reconnects to a host.
* guix/scripts/substitute.scm (open-connection-for-uri/maybe): Transform in to
call-with-connection-error-handling.
(fetch-narinfos): Use call-with-connection-error-handling.
(process-query): Replace open-connection-for-uri/maybe with
open-connection-for-uri/cached.
(open-connection-for-uri/cached): Set a default timeout, matching the
behaviour in open-connection-for-uri/maybe.
(process-substitution): Use call-with-connection-error-handling.
At least by default. Instead, make the open-connection procedure a parameter,
and make the default guix:open-connection-for-uri. Do so similarly for
lookup-narinfos and lookup-narinfos/diverse which work towards calling
fetch-narinfos.
This means this code can be moved to a different module, without having
use/move the connection caching code.
* guix/scripts/substitute.scm (fetch-narinfos): Add #:open-connection
argument, and call http-multiple-get with it.
(lookup-narinfos) Add #:open-connection argument, and call fetch-narinfos with
it.
(lookup-narinfos/diverse): Add #:open-connection argument, and call
lookup-narinfos with it.
(process-query): Call lookup-narinfos/diverse with #:open-connection
open-connection-for-uri/maybe.
As it's only called in one place, and this should make the code easier to
read.
* guix/scripts/substitute.scm (fetch): Move procedure inside…
(process-substitution): …here.
It's just called in one place, with hardcoded argument values, so just inline
them.
* guix/scripts/substitute.scm (fetch): Remove arguments that don't vary, copy
the values from the call site in process-substitution.
(process-substitution): Remove unnecessary argument values from fetch call.
Failures now should be handled where they occur, and if there's a problem
that's symptomatic of an issue with the connection, the port should be closed.
* guix/scripts/substitute.scm (call-with-cached-connection): Remove procedure.
(with-cached-connection): Remove syntax rule.
Just pass open-connection-for-uri/maybe to http-fetch, this removes the need
for with-cached-connection and passing the port in.
* guix/scripts/substitute.scm (fetch): Don't take a port as an argument, and
pass open-connection-for-uri/maybe to http-fetch.
(process-substitution): Don't call fetch with with-cached-connection.
Instead, just pass open-connection-for-uri/maybe to http-multiple-get. This
code should be functionaly similar to the previous code. The eventual aim of
this is to make the connection caching not mandatory in fetch-narinfos.
* guix/scripts/substitute.scm (fetch-narinfos): Remove use of
call-with-cached-connection.
As this is used by http-fetch and http-multiple-get when they call the
specified open connection procedure.
* guix/scripts/substitute.scm (open-connection-for-uri/maybe): Support
#:verify-certificate?.
From (guix scripts substitute). This will make it easier to reuse this code.
* guix/scripts/substitute.scm (http-multiple-get): Remove, and move to…
* guix/http-client.scm (http-multiple-get): …here.

This change turned out to be misguided; it would lead to "substitute:"
lines being printed on the client side, without anything beyond the
colon sign.

This separation between the code for dealing with narinfos from the code doing
that for a purpose should make things clearer, and better support components
other that the substitute script in using this code.
This is just moving the code around, no code should have been significantly
changed.
* guix/scripts/substitute.scm (<narinfo>): Move record type to (guix narinfo).

narinfo-signature->canonical-sexp, narinfo-maker, read-narinfo,
narinfo-sha256, valid-narinfo?, write-narinfo, narinfo->string,
string->narinfo, equivalent-narinfo?, supported-compression?,
compresses-better?, narinfo-best-uri): Move procedures to (guix narinfo).

* po/guix/POTFILES.in: Add 'guix/narinfo.scm'.
Rather than having valid-narinfo? evaluate to #t if
%allow-unauthenticated-substitutes? is set to #t, just use (const #t) for
valid-narinfo? when %allow-unauthenticated-substitutes? is set to #t. This
will allow moving valid-narinfo? in to a (guix substitutes) module.
* guix/scripts/substitute.scm (process-query, process-substitution): Change
the authorized? argument to lookup-narinfo and lookup-narinfos/diverse based
on %allow-unauthenticated-substitutes?.
(valid-narinfo?): Remove use of %allow-unauthenticated-substitutes?.
