This allows 'guix publish' to compress and advertise multiple
compression methods from which users can choose.
* guix/scripts/publish.scm (actual-compression): Rename to...
(actual-compressions): ... this. Expect REQUESTED to be a list, and
always return a list.
(%default-options): Remove 'compression.
(store-item->recutils): New procedure.
(narinfo-string): Change #:compression to #:compressions (plural).
Adjust accordingly.
(render-narinfo, render-narinfo/cached): Likewise.
(bake-narinfo+nar): Change #:compression to #:compressions.
[compressed-nar-size]: New procedure.
Call 'compress-nar' for each item returned by 'actual-compressions'.
Create a narinfo for each compression.
(effective-compression): New procedure.
(make-request-handler): Change #:compression to #:compressions.
Use 'effective-compression' to determine the applicable compression.
(guix-publish): Adjust handling of '--compression'.
Print a message for each compression that is enabled.
* tests/publish.scm ("/*.narinfo"): Adjust to new narinfo field
ordering.
("/*.narinfo with properly encoded '+' sign"): Likewise.
("/*.narinfo with lzip + gzip"): New test.
("with cache, lzip + gzip"): New test.
* doc/guix.texi (Invoking guix publish): Document it.
* guix/scripts/publish.scm (guix-publish): Use 'info' instead of
'format' for the initial message. When COMPRESSION is true, display the
method and level in use.
Fixes <https://bugs.gnu.org/33721>.
Reported by Chris Marusich <cmmarusich@gmail.com>.
* guix/scripts/publish.scm (render-nar/cached): Add #:ttl and honor it.
(make-request-handler): Pass #:ttl to 'render-nar/cached'.
* tests/publish.scm ("with cache, uncompressed"): Pass "--ttl=42h" to
'guix publish'. Check 'Cache-Control' on narinfo response and on nar
response.
Fixes <https://bugs.gnu.org/30184>.
Regression introduced in 297e04d660.
Reported by Christopher Baines <mail@cbaines.net>.
* guix/scripts/publish.scm (nar-response-port): Add 'compression'
parameter and honor it.
(http-write): Get 'x-nar-compression' from the initial RESPONSE.
This was harmless but non-compliant and unnecessary.
* guix/scripts/publish.scm <top level>: Rename "Guix-Nar-Compression" to
"X-Nar-Compression" as should have always been.
(render-nar, nar-response-port): Adjust accordingly.
(strip-headers): New procedure.
(sans-content-length, with-content-length): Use it.
This adjusts the workaround for <http://bugs.gnu.org/21093> so that it's
not limited to a single content-type.
* guix/scripts/publish.scm (render-nar/cached): Add the 'x-raw-file'
header on the response.
(render-content-addressed-file): Likewise.
(with-content-length): Remove the 'x-raw-file' header.
(http-write): Instead of dispatching on 'application/octet-stream',
check whether 'x-raw-file' is set to determine whether to spawn a
thread.
This saves 18 bytes on each 404 narinfo response.
* guix/scripts/publish.scm (render-narinfo): Pass #:phrase to
'not-found'.
(render-narinfo/cached): Likewise.
Fixes <https://bugs.gnu.org/28664>.
Reported by Maxim Cournoyer <maxim.cournoyer@gmail.com>.
* guix/scripts/publish.scm (bake-narinfo+nar): When COMPRESSION is
'none, write NAR instead of doing nothing.
(make-request-handler): Use 'render-nar/cached' for /nar URLs with no
compression.
* tests/publish.scm ("with cache", "with cache, uncompressed"): Adjust
expected result accordingly.
Suggested by Mark H Weaver <mhw@netris.org>.
* guix/scripts/publish.scm (nar-expiration-time): New procedure.
(render-narinfo/cached): Use it as the #:entry-expiration passed to
'maybe-remove-expired-cache-entries'.
This avoids the open/fstat/close syscalls upon a cache hit that we had
with the previous idiom:
(call-with-input-file file read-derivation)
where caching happened in 'read-derivation' itself.
* guix/derivations.scm (%read-derivation): Rename to...
(read-derivation): ... this.
(read-derivation-from-file): New procedure.
(derivation-prerequisites, substitution-oracle)
(derivation-prerequisites-to-build):
(derivation-path->output-path, derivation-path->output-paths):
(derivation-path->base16-hash, map-derivation): Use
'read-derivation-from-file' instead of (call-with-input-file …
read-derivation).
* guix/grafts.scm (item->deriver): Likewise.
* guix/scripts/build.scm (log-url, options->things-to-build): Likewise.
* guix/scripts/graph.scm (file->derivation): Remove.
(derivation-dependencies, %derivation-node-type): Use
'read-derivation-from-file' instead.
* guix/scripts/offload.scm (guix-offload): Likewise.
* guix/scripts/perform-download.scm (guix-perform-download): Likewise.
* guix/scripts/publish.scm (load-derivation): Remove.
(narinfo-string): Use 'read-derivation-from-file'.
This allows 'guix publish' threads as well as 'guix substitute' and
'guix offload' processes to be properly labeled in 'top', 'pstree', etc.
* guix/workers.scm (worker-thunk): Add #:thread-name parameter and honor it.
(make-pool): Likewise.
* guix/scripts/publish.scm (http-write): Add calls to 'set-thread-name'
in bodies of 'call-with-new-thread'.
(guix-publish): Call 'set-thread-name'. Pass #:thread-name to 'make-pool'.
* guix/scripts/offload.scm (guix-offload): Call 'set-thread-name'.
* guix/scripts/substitute.scm (guix-substitute): Likewise.
Before this patch, there was a possibility that we'd queue several
baking tasks for the same item. The first one would bake the item but
subsequent tasks wouldn't check whether the item had been baked in the
meantime and would re-bake it.
* guix/scripts/publish.scm (render-narinfo/cached): Don't call
'bake-narinfo+nar' when (file-exists? cached).
Fixes <http://bugs.gnu.org/26975>.
Reported by Mark H Weaver <mhw@netris.org>.
* guix/scripts/publish.scm (bake-narinfo+nar): Pass #f as the 2nd
argument to 'stat' and properly handle #f.
* tests/publish.scm (wait-for-file): New procedure.
("with cache"): Remove 'wait-for-file' procedure.
("with cache, uncompressed"): New test.
* guix/scripts/publish.scm (not-found): Add #:phrase and #:ttl
parameters and honor them.
* tests/publish.scm ("with cache"): Check the 'cache-control' header on
of the 404 response.
* guix/scripts/publish.scm (narinfo-string): Add #:file-size parameter.
Produce a "FileSize" field when COMPRESSION is eq? to '%no-compression'
or when FILE-SIZE is true.
(bake-narinfo+nar): Pass #:file-size.
* tests/publish.scm ("/*.narinfo")
("/*.narinfo with properly encoded '+' sign")
("with cache"): Check for "FileSize".

* guix/scripts/publish.scm (render-home-page): New procedure.
(make-request-handler): Handle it.
* guix/scripts/publish.scm (narinfo-files): New procedure.
(render-narinfo/cached)[delete-file]: New procedure. Add call to
'maybe-remove-expired-cache-entries'.
* doc/guix.texi (Invoking guix publish): Document the interation between
--cache and --ttl.
Fixes <http://bugs.gnu.org/26201>.
Reported by <dian_cecht@zoho.com>.
These options allow nars to be "baked" off-line and cached instead of
being compressed on the fly. As a side-effect, this allows us to
provide a 'Content-Length' header for nars.
* guix/scripts/publish.scm (show-help, %options): Add '--cache' and
'--workers'.
(%default-options): Add 'workers'.
(nar-cache-file, narinfo-cache-file, run-single-baker): New procedures.
(single-baker): New macro.
(render-narinfo/cached, bake-narinfo+nar)
(render-nar/cached): New procedures.
(make-request-handler): Add #:cache and #:pool parameters and honor
them.
(run-publish-server): Likewise.
(guix-publish): Honor '--cache' and '--workers'.
* tests/publish.scm ("with cache"): New test.
* doc/guix.texi (Invoking guix publish): Document it.
* guix/scripts/publish.scm (narinfo-string): Force %NO-COMPRESSION when
STORE-PATH matches 'compressed-file?'.
* guix/utils.scm (compressed-file?): New procedure.
* tests/publish.scm ("/*.narinfo for a compressed file"): New test.
* guix/scripts/publish.scm (show-help, %options): Add '--compression'.
(<compression>): New record type.
(%no-compression, %default-gzip-compression): New variables.
(%default-options): Add 'compression' key.
(narinfo-string): Add #:compression parameter and honor it.
(render-narinfo): Likewise.
(render-nar): Likewise.
<top level>: Add call to 'declare-header!'.
(swallow-zlib-error): New macro.
(nar-response-port): New procedure.
(http-write): Add call to 'force-output'. Use 'nar-response-port'
instead of 'response-port'. Use 'swallow-zlib-error'.
(make-request-handler): Add #:compression parameter and honor it. Add
"nar/gzip" URL handler.
(run-publish-server): Add #:compression parameter and honor it.
(guix-publish): Honor --compression.
* tests/publish.scm (http-get-port, wait-until-ready): New procedures.
<top level>: Run main server with "-C0". Call 'wait-until-ready'.
("/nar/gzip/*", "/*.narinfo with compression"): New tests.
* doc/guix.texi (Invoking guix publish): Document it.
* guix/scripts/publish.scm (show-help, %options): Add --ttl.
(render-narinfo): Add #:ttl and honor it.
(make-request-handler): Add #:narinfo-ttl and honor it.
(run-publish-server): Likewise.
(guix-publish): Honor --ttl, pass it to 'run-publish-server'.
Fixes <http://bugs.gnu.org/21888>.
Reported by iyzsong@member.fsf.org (宋文武).
* guix/scripts/publish.scm (narinfo-string): Use
'encode-and-join-uri-path' instead of 'string-append' to compute URL.
* tests/publish.scm ("/*.narinfo with properly encoded '+' sign"):
("/nar/ with properly encoded '+' sign"): New tests.
* guix/store.scm (read-path-info): Use #f when we get the empty string
for DERIVER.
* guix/scripts/publish.scm (narinfo-string): Adjust accordingly.
* tests/store.scm ("path-info-deriver"): New test.
Before that, /nar requests could succeed if the requested store item
exists but is invalid (although such requests were unlikely because the
corresponding narinfo request would have failed.)
* guix/scripts/publish.scm (render-nar): Add 'store' parameter. Use
'valid-path?' instead of 'file-exists?'.
(make-request-handler): Adjust 'render-nar' call accordingly.
* tests/publish.scm ("/nar/invalid"): New test.
A client closing the connection while reading from a /nar URL would
leave an open file descriptor in the server. This patch fixes it.
* guix/scripts/publish.scm (swallow-EPIPE): New macro.
(http-write): Use it around 'write-file' call.
* guix/scripts/publish.scm (narinfo-string): Catch 'system-error' around
'load-derivation' call; return BASE-INFO upon ENOENT. This allows us
to return the narinfo even if DERIVER is missing. Before that, the
exception would be uncaught, leading to 500 Internal Error on the
client side.
Previously, before replying to a /nar/* request, 'guix publish' would first
build up the whole nar into memory (as a consequence of
<http://bugs.gnu.org/21093>), which obviously doesn't scale.
* guix/scripts/publish.scm (render-nar): Return STORE-PATH instead of a
procedure that calls 'write-file'.
(sans-content-length): New procedure.
(http-write): For 'x-nix-archive', don't call '%http-write'. Instead, call
'write-file' right from here, using BODY as the file name.
