Subject: [PATCH] server: Allow -D nbdkit.* debug flags for the core server.
These work like plugin/filter debug flags, but apply to the internals
of the server.
(cherry picked from commit 3b45db234a691f8ff926a6fef583e11c3601f112)

Subject: [PATCH] server: Allow -D debug flags to contain dots for namespacing.
This is just a convenience. Either of:
-D myplugin.foo_bar=1
-D myplugin.foo.bar=1
correspond to the same plugin variable "myplugin_debug_foo_bar".

Subject: [PATCH] server: Add -D nbdkit.backend.controlpath and -D
nbdkit.backend.datapath.
These can be used to suppress verbose debugging messages from the
backend.

Cherry picked from commit 231717e8cd5f27d76631be6651062d5a5ccf7fdc.

+
+As well as enabling or disabling debugging in the server using
+I<--verbose> you can control extra debugging in the server using the
+C<-D nbdkit.*> flags listed in this section. Note these flags are an
+internal implementation detail of the server and may be changed or

+
+These flags control the verbosity of nbdkit backend debugging messages
+(the ones which show every request processed by the server). The
+default for both settings is C<1> (normal debugging) but you can set
+them to C<0> to suppress these messages.

+suppress messages about pread, pwrite, zero, trim, etc. commands.
+When transferring large amounts of data these messages are numerous

Subject: [PATCH] python: Add various constants to the API.
These are accessible from the plugin by:
import nbdkit
if flags & nbdkit.FLAG_MAY_TRIM:
&c.
Many (all?) of these are not yet useful for plugins, some will never
be useful, but they only consume a tiny bit of memory and it's nice to
have the complete set available for future use.

From 49ef7e7d7c3602cc8e53d2052fce9d3a12840ea2 Mon Sep 17 00:00:00 2001

Date: Thu, 21 Nov 2019 15:44:39 +0000
Subject: [PATCH] python: Implement nbdkit API version 2.
To avoid breaking existing plugins, Python plugins wishing to use
version 2 of the API must opt in by declaring:
API_VERSION = 2
(Plugins which do not do this are assumed to want API version 1).
For v2 API, we also avoid a copy by passing a buffer into pread.
It's more efficient if we pass the C buffer directly to Python code.
In some cases the Python code will be able to write directly into the
C buffer using functions like file.readinto and socket.recv_into.
This avoids an extra copy.
Thanks: Nir Soffer

+=head1 NAME
+
+nbdkit-extentlist-filter - place extent list over a plugin
+
+=head1 SYNOPSIS
+
+ nbdkit --filter=extentlist plugin extentlist=FILENAME
+
+=head1 DESCRIPTION
+
+C<nbdkit-extentlist-filter> is an nbdkit filter lets you place a
+static list of extents on top of an existing plugin. Extents record
+whether or not specific parts of the disk are allocated or sparse.
+
+You can use this with plugins which cannot get extent information
+themselves, but you can get this information from another source. One
+place where it is useful is with L<nbdkit-ssh-plugin(1)> because the
+sftp protocol does not support reading sparseness information, but you
+may be able to get this information directly from the source disk on
+the remote server.
+
+=head1 FILE FORMAT
+
+The list of extents is specified in a text file. There is one extent
+specified per line. Each line has the format:
+
+ offset length type
+
+The C<offset> and C<length> fields may use any format understood by
+C<nbdkit_parse_size>. The optional C<type> field may be an integer,
+missing (same as 0), or a comma-separated list of the words C<hole>
+and C<zero>. (The fields correspond to the inputs of the
+C<nbdkit_add_extent> function, see L<nbdkit-plugin(3)>).
+
+An example of a valid set of extents covering a C<10M> disk where the
+first megabyte only is allocated data:
+
+ 0 1M
+ 1M 9M hole,zero
+
+Or you could omit the C<hole,zero> extent since any gaps are assumed
+to be holes with that type:
+
+ 0 1M
+
+The extent list need not cover the whole disk, and does not need to be
+in ascending order, but it must I<not> contain overlapping extents.
+
+=head1 PARAMETERS

%description
NBD is a protocol for accessing block devices (hard disks and
disk-like things) over the network.
nbdkit is a toolkit for creating NBD servers.
The key features are:
* Multithreaded NBD server written in C with good performance.
* Minimal dependencies for the basic server.
* Liberal license (BSD) allows nbdkit to be linked to proprietary
libraries or included in proprietary code.
* Well-documented, simple plugin API with a stable ABI guarantee.
Lets you to export "unconventional" block devices easily.
* You can write plugins in C or many other languages.
* Filters can be stacked in front of plugins to transform the output.
In Red Hat Enterprise Linux, '%{name}' is a meta-package which pulls
in the core server and a useful subset of plugins and filters.
If you want just the server, install '%{name}-server'.
To develop plugins, install the '%{name}-devel' package and start by
reading the nbdkit(1) and nbdkit-plugin(3) manual pages.
