From bfa0b1238f6318d06930ec4d389a27932fc90a16 Mon Sep 17 00:00:00 2001
From: "Richard W.M. Jones" <rjones@redhat.com>
Date: Sat, 4 Feb 2023 12:34:57 +0000
Subject: [PATCH] curl: Use the parallel thread model
After previous changes, it is now safe to use the parallel thread
model in this plugin. The locking in pool.c protects a single curl
handle from being used from multiple threads.
An advantage of this is we can now combine the curl plugin with
filters such as readahead and scan.
This pessimizes some workloads and improves others. See my earlier
comments here:
https://listman.redhat.com/archives/libguestfs/2023-February/030610.html
https://listman.redhat.com/archives/libguestfs/2023-February/030618.html
https://listman.redhat.com/archives/libguestfs/2023-February/030619.html
https://listman.redhat.com/archives/libguestfs/2023-February/030620.html
Tests below use this basic command:
$ time nbdkit -r -U - curl https://cloud.debian.org/images/cloud/bookworm/daily/latest/debian-12-generic-amd64-daily.qcow2 \
--run '$COPY $uri /var/tmp/out'
where $COPY is either nbdcopy or qemu-img convert.
Before this change:
nbdkit + nbdcopy 0m55.397s
nbdkit + qemu-img convert [over 20 minutes]
After this change:
nbdkit + nbdcopy 1m1.235s
nbdkit + qemu-img convert 6m3.262s
nbdkit --filter=readahead --filter=cache + qemu-img convert
8m16.488s
nbdkit connections=8 + qemu-img convert
3m48.502s
Previously [see first link above] we noted that file: URLs are
impacted, and indeed they are, with this command:
$ time nbdkit -r -U - curl file:/var/tmp/fedora-36.img \
--run 'nbdcopy --no-extents -p "$uri" null:'
nearly doubling in run-time (0.78 -> 1.34). However I think this may
be a peculiarity of curl's handling of file. (Use nbdkit-file-plugin
instead).
Note the fundamental issue here is still lack of multiconn support in
qemu's NBD client.

Subject: [PATCH] curl: Use _Atomic type to accumulate curl timings
Because the global list of times is accessed in parallel by many
threads, they must be accessed atomically.

Enhance debugging output with connection (conn) and transfer (xfer)
IDs. Since there is some overhead to doing this, don't do it by
default. Also it requires libcurl >= 8.2.0.

Subject: [PATCH] pool: Add outline get_ready and after_fork functions
In a forthcoming commit we will need to create a multi handle and a
background thread, requiring use of the .get_ready (for multi) and
.after_fork (for the thread) plugin methods. This commit removes the
empty load_pool function and adds pool_get_ready and pool_after_fork,
and the associated machinery in curl.c.
This commit on its own does nothing, future commits will fill in these
functions with useful work.

Subject: [PATCH] curl: Do pool_unload before config_unload
Since config.c deals with handles (and contains free_handle), and
since pool_unload calls free_handle to free handles, it's better to do
pool_unload first.
I don't believe this is a correctness issue now, but it will be in
subsequent commits.

Subject: [PATCH] retry-request: Allow get_size operation to be retried
This plugin operation might need to do some real work (instead of just
fetching a number from memory), and so it might have to be retried.
In particular, changes to the curl plugin make .get_size into a
heavyweight operation, where previously it was done as a side-effect
of .open. And so we must allow .get_size to be retried independent of
.open.

Subject: [PATCH] curl: Redefine connections=<N> parameter as number of HTTP
connections
Previously (nbdkit 1.34) this was the number of easy handles. However
it turns out that easy handles can open multiple HTTP connections, and
in fact there's no good way to tell how many (and they are not
shared).
Now that we are using a curl multi, curl >= 7.30 provides a way to
limit the total number of actual HTTP connections, so we should just
use it. This is closer to what I intended this parameter to mean.
Also update the documentation to properly describe previous and
current behaviour.

-4). Note that if there are more than 4 NBD connections, they will
-share the 4 web server connections, unless you adjust C<connections>.
+nbdkit 1.34 changed to using a fixed pool of libcurl handles shared
+across all NBD connections. You can control the maximum number of
+curl handles in the pool with the C<connections> parameter (default
+4). Since each curl handle maintains a small cache of connections,
+this meant that the number of HTTP connections would be a small
+multiple of the C<connections> parameter. If there are more than 4
+incoming NBD connections, they will contend for the libcurl handles,
+unless you adjust C<connections>.
+
+nbdkit E<ge> 1.36 changed again to use a curl multi handle
+(L<libcurl-multi(3)>). Now the C<connections> parameter controls the
+maximum number of HTTP connections made to the remote server
+(L<CURLMOPT_MAX_TOTAL_CONNECTIONS(3)>). This is more efficient
+especially with HTTP/2 and HTTP/3, where each HTTP connection can
+contain a very large number of streams (typically up to 100)
+multiplexed over one connection. The default for C<connections> was
+raised to 16.

From 852f23db007b13ca8e9e5548c3becbdc78e16601 Mon Sep 17 00:00:00 2001

Subject: [PATCH] curl: Disable this plugin on Windows
There is no self pipe trick for Windows (or there is, but it would
require substantial porting work).
(cherry picked from commit 9b0759377f6779bbecc8647c026dcdac7f2ebd89)
