[PATCH nbdkit 0/4] server: Add nbdkit_shutdown() call and two new filters.
This adds a new nbdkit_shutdown() API whereby plugins and filters can
request that the server shuts down (asynchronously) during the serving
phase.
Two new filters are added, one of which depends on this feature and
the other not needing it but being somewhat related.

[nbdkit PATCH 0/3] Content differentiation during --tls=on
Patch 3 still needs tests added, but it is at least working from
my simple command line tests.

server: Implement nbdkit_is_tls for use during .open
server: Expose final thread_model to filter's .get_ready

[PATCH nbdkit INCOMPLETE] New filter: exitwhen: exit gracefully when an event occurs.
This incomplete patch adds a new filter allowing more control over
when nbdkit exits. You can now get nbdkit to exit gracefully on
certain events, such as a file being created, a pipe held open by
another process going away, or when another PID exits. There is also
a script option to allow for completely custom events.
It is untested at the moment, I'm posting it to get feedback on the

[nbdkit PATCH v2 0/8] exportname filter
This is a revision of my .default_export work, plus new work on
.export_descriptions and a new exportname filter. I think it is
now ready to check in.
Things I'd still like in 1.22:
- the file plugin should implement .list_exports (patch already posted,
but it needs rebasing on this series)
- the ext2 filter should override .list_exports when in exportname mode
- the nbd plugin should be

Re: Plans for nbdkit 1.18 release?

Did you want to take this one any further? It might be one that we
save for > 1.18:

Another thing I've been thinking about for some time is splitting
.config_complete into .config_complete + .get_ready (new name TBD).
At the moment .config_complete is both the place where we finish
processing config, and

[PATCH nbdkit 0/5] server: Add .get_ready callback.
I like this change. I think we were overloading the config_complete
method before to do two different things (complete configuration; do
any allocation/housekeeping necessary before we can start serving).
The only questions in my mind are whether we want this before 1.18,
and whether the name ("get_ready") is a good one.

[nbdkit PATCH v3 00/14] exportname filter
It's been several weeks since I posted v2 (I got distracted by
improving libnbd to better test things, which in turn surfaced some
major memory leak problems in nbdsh that are now fixed). Many of the
patches are minor rebases from v2, with the biggest changes being
fallout from:
- patch 2: rename nbdkit_add_default_export to nbdkit_use_default_export
- overall: this missed 1.22, so update

[nbdkit PATCH 0/4] More .list_exports uses
Here's changes to the file plugin (which I'm happy with) and a new
exportname filter (which is still at RFC stage; I need to finish
implementing strict mode in .open, and add tests).
I also discovered that we really want .list_exports and .open to know
when they are used on plaintext vs. tls clients for --tls=on, and we
may want to split out a new .default_export callback rather than

[nbdkit PATCH 0/3] Add noparallel filter
Being able to programmatically force nbdkit to be less parallel can be
useful during testing. I was less sure about patch 3, but if you like
it, I'm inclined to instead squash it into patch 1. This patch is
written to apply after my NBD_CMD_CACHE work (since I touched the
nocache filter); but can be rearranged if we think this series should
go in first while that one undergoes any adjustments

[nbdkit PATCH v2 0/5] .list_exports
Since v1:
- patch 1: check size limits
- patch 2: better handling of default export name canonicalization

- patch 4: new
- patch 5: rewrite sh parser, fix testsuite to actually work and
cover more cases (now that libnbd.git is fixed)

[nbdkit PATCH 0/5] Implement .default_export, nbdkit_string_intern
More patches on the way for improving .list_exports signature and
adding .export_description, but this is the promised code showing
why nbdkit_string_intern is useful. Patch 4 is somewhat RFC: we
could either add new API to take the boilerplate from:
foo_config(const char *key, const char *value) {
if (strcmp (key, "file") == 0) {
CLEANUP_FREE char *tmp = nbdkit_realpath (value);

[PATCH nbdkit 0/2] Temporarily remove .list_exports for nbdkit 1.22
If you're following nbdkit development upstream you'll have seen that
we are still making changes to the .list_exports and related APIs.
The current .list_exports API upstream is not how it will look
finally. The latest set of proposals was here:
https://www.redhat.com/archives/libguestfs/2020-August/thread.html#00330
At the same time I'd like to do an nbdkit 1.22 (stable) release.

[PATCH nbdkit] tar as a filter.
For review only, this needs some clean up and more tests.
My eyes are going cross-eyed looking at the calculate_offset_of_entry
function, so time to take a break ...

[nbdkit PATCH 0/2] Avoid oddities with files unaligned to granularity
When using a filter that rounds up to alignment boundaries, the tail
bytes of the plugin are difficult to access correctly. Rather than
duplicating lots of code already in the truncate filter, it's easier
to just make the other filters default to rounding down and add doc
links on how to round up instead.

Cross-project NBD extension proposal: NBD_INFO_INIT_STATE
I will be following up to this email with four separate threads each
addressed to the appropriate single list, with proposed changes to:
- the NBD protocol
- qemu: both server and client
- libnbd: client
- nbdkit: server
The feature in question adds a new optional NBD_INFO_ packet to the
NBD_OPT_GO portion of handshake, adding up to 16 bits of information
that the server can advertise to the

[RFC nbdkit PATCH 0/3] aligned .extents
Ultimately, both the blocksize and swab filters want to return aligned
extents to the client. I'm posting this as a snapshot of my work in
progress on how I plan to get there (it's not quite working yet, but
I'm done for today and wanted to at least document my ideas).
I might also add a convenience function for nbdkit_extents_offset,

[PATCH nbdkit 0/3] tar: Implement tar-limit
This patch series cleans up some issues with nbdkit-tar-filter and (in
patch 3) implements a new tar-limit feature which limits how much of
the tar file we will read to find the entry within the tar file that
we will serve. This protects against the case where a tar file is
presented that contains much content at the front that we must iterate
over (and download) before we get to the entry we are

Rebased filters patch. Requires current git master + the locks /

So a few changes here since last time:
The "introduce filters" and "implement filters" patches are

I introduced a concept of .prepare and .finalize. These run before
