Jason Wessel b709c3c67b fsck: Implement a partial commit reason bitmask
After the corruption has been fixed with "ostree fsck -a --delete", a
second run of the "ostree fsck" command will print X partial commits
not verified and exit with a zero.

The zero exit code makes it hard to detect if a repair operation needs
to be run.  When ever fsck creates a partial commit it should add a
reason for the partial commit to the state file found in
state/<hash>.commitpartial.  This will allow a future execution of the
fsck to still return an error indicating that the repository is still
in the damaged state, awaiting repair.

Additional reason codes could be added in the future for why a partial
commit exists.

Text from: https://github.com/ostreedev/ostree/pull/1880
====
cgwalters commented:

To restate, the core issue is that it's valid to have partial commits
for reasons other than fsck pruned bad objects, and libostree doesn't
have a way to distinguish.

Another option perhaps is to write e.g. fsck-partial into the
statefile state/<hash>.commitpartial which would mean "partial, and
expected to exist but was pruned by fsck" and fsck would continue to
error out until the commit was re-pulled. Right now the partial stamp
file is empty, so it'd be fully compatible to write a rationale into
it.

Dan Nicholson e49060c207 lib/gpg: Use g_spawn_sync to kill gpg-agent
For reasons I don't understand, GSubprocess doesn't play nice with KDE's
plasmashell. I assume this has something to do with the GSubprocess
using the glib worker thread while plasmashell uses the glib main
loop. Instead, just use g_spawn_sync to fork and wait in the current
thread.

Dan Nicholson d14472a7f0 lib/gpg: Don't kill gpg-agent on newer gnupg
GnuPG 2.1.17 contains a bug fix so that `gpg-agent` is killed when the
entire GPG home directory is deleted[1]. If the host's GnuPG is new
enough, then we don't need to bother calling `gpg-connect-agent` to kill
the agent since it will be cleaned up on its own.

Get the GnuPG version from the GPGME OpenPGP engine info and parse it to
see if it matches this criteria.

Dan Nicholson 522d31b2d4 lib/gpg: Only show gpg-connect-agent stderr on failures
When listing GPG keys, the temporary GPG homedir will be constructed by
simply copying the remote's trusted keys to the pubring.gpg file. In
that case, no GPG operations spawning gpg-agent will be run. When
gpg-connect-agent is run to cleanup the homedir, it will helpfully print
on stderr that it's starting gpg-agent like so:

gpg-connect-agent: no running gpg-agent - starting '/usr/bin/gpg-agent'
gpg-connect-agent: waiting for the agent to come up ... (5s)
gpg-connect-agent: connection to agent established

Send gpg-connect-agent's stderr to a pipe and only send it to the
application's stderr if an error was encountered.

Javier Martinez Canillas d42f970ed3 lib/bootconfig-parser: Always include deployment index in BLS title
If there are different deployments for the same commit version, the BLS
snippets will have the same title fields (but different version fields):

$ grep title *
ostree-1-testos.conf:title TestOS 42 20190902.0 (ostree)
ostree-2-testos.conf:title TestOS 42 20190902.0 (ostree)
ostree-3-testos.conf:title TestOS 42 20190902.0 (ostree)

But bootloaders could expect the title field to be unique for BLS files.
For example, the zipl bootloader used in the s390x architecture uses the
field to name the boot sections that are created from the BLS snippets.

So two BLS snippets having the same title would lead to zipl failing to
create the IPL boot sections because they would have duplicated names:

$ zipl
Using config file '/etc/zipl.conf'
Using BLS config file '/boot/loader/entries/ostree-3-testos.conf'
Using BLS config file '/boot/loader/entries/ostree-2-testos.conf'
Using BLS config file '/boot/loader/entries/ostree-1-testos.conf'
Error: Config file '/etc/zipl.conf': Line 0: section name 'TestOS 42 20190902.0 (ostree)' already specified

Avoid this by always including the deployment index along with the commit
version in the title field, so this will be unique even if there are BLS
files for deployments that use the same commit version:

$ grep title *
ostree-1-testos.conf:title TestOS 42 20190902.0 (ostree:2)
ostree-2-testos.conf:title TestOS 42 20190902.0 (ostree:1)
ostree-3-testos.conf:title TestOS 42 20190902.0 (ostree:0)

Javier Martinez Canillas 2ca2b88f51 lib/bootconfig-parser: Write BLS fragment fields in a deterministic order
Currently the BLS fragments fields write is non-determinisitc. The order
of the fields will depend on how the iterator of the options GHashTable
iterates over the key/value pairs.

But some bootloaders expect the fields to be written in a certain order.
For example the zipl bootloader (used in the s390x architecture) fails to
parse BLS files if the first field is not the 'title' field, since that's
used to name the zipl boot sections that are created from the BLS files.

Write the fields in a deterministic order, following what is used in the
example file of the BootLoaderspec document:

Javier Martinez Canillas f82f825fed lib/bootconfig-parser: Remove support to preserve comments in BLS files
OSTree has some logic to preserve comment lines in the BLS fragments, but
the BLS fragments are always created on new deployments so the comments
are never carried.

Also, OSTree never writes BLS fragments with comments so these will only
be present in BLS files that were modified outside of OSTree. Something
that should be avoided in general.

Finally, there is a bug in the logic that causes BLS files to have lines
with only a newline character.

The ostree_bootconfig_parser_parse_at() function reads the bootconfig file
using glnx_fd_readall_utf8() but this function NUL terminates the returned
string with the file contents.

So when the string is later split using '\n' as delimiter, the last token
is set to '\0' and a wrong GVariant will be added to the lines GPtrArray
in the OstreeBootconfigParser struct.

This will lead to bootconfig files that contains lines with only a newline
character, since the key in the GVariant would be set to NUL and won't be
present in the options GHashTable of the OstreeBootconfigParser struct.

So let's just remove that logic since is never used and makes BLS files to
have wrong empty lines.

Colin Walters 93999d337e sysroot: Add a clearer error if /boot/loader isn't found
I've seen people confused by this error in the case where

If you understand ostree deeply it's clear but, let's do
better here and a direct error message for the case where
we can't find `/boot/loader` which is the majority of these.

The other case could happen if e.g. just the BLS fragment

Jonathan Lebon 0c48769de3 bin: Better handle --
We would stop passing through `--` and args after it to the underlying
command in `ostree_run`. This made it impossible to use `--` to tell the
parser that following args starting with `-` really are positional.

AFAICT, that logic for `--` here came from a time when we parse options
manually in a big loop, in which case breaking out made sense (see
97558276e4).

There's an extra step here, which is that glib by default leaves the
`--` in the list of args, so we need to take care to remove it from the
list after parsing.

Otherwise, we'll be subject to whatever `umask` is currently. Normally,
processes should respect `umask` when creating files and directories,
but specifically for `ostree admin unlock` (or `rpm-ostree usroverlay`),
this poses a problem since e.g. a `/usr` with mode 0700 will break any
daemon that doesn't run as root and needs to read files under `/usr`,
such as polkitd.

This patch just does a `chmod()` after the `mkdir()`. An alternative
would be to do `umask(0000)` after forking into the child process
that'll call `mount()`, but that'd require also moving the `mkdir()`
calls into there, making for a more intrusive patch.

Matthew Leeds 78747a8a17 lib/repo-refs: Allow resolving local collection-refs
Currently for a "normal" refspec you can choose to use
ostree_repo_resolve_rev_ext() instead of ostree_repo_resolve_rev() if
you only want to look at local refs (in refs/heads/) not remote ones.
This commit provides the analogous functionality for
ostree_repo_resolve_collection_ref() by adding a flag
OSTREE_REPO_RESOLVE_REV_EXT_LOCAL_ONLY and implementing it. This
will be used by Flatpak.

Matthew Leeds 0ecbc6f2a9 lib/repo-refs: Add a flag to exclude listing from refs/mirrors
Currently the flag OSTREE_REPO_LIST_REFS_EXT_EXCLUDE_REMOTES for
ostree_repo_list_collection_refs() means that refs in refs/remotes/
should be excluded but refs in refs/mirrors/ should still be checked, in
addition to refs/heads/ which is always checked. However in some
situations you want to exclude both remote and mirrored refs and only
check local "owned" ones. So this
commit adds a new flag OSTREE_REPO_LIST_REFS_EXT_EXCLUDE_MIRRORS which
lets you exclude refs/mirrors/ from the listing.

This way we can avoid breaking API but still allow the listing of local
collection-refs.

The impetus for this change is that I'm changing Flatpak to make more
use of refs/mirrors, and we need a way to specify that a collection-ref
is local when using ostree_repo_resolve_collection_ref() in, for
example, the implementation of the repo command. The subsequent commit
will make the changes needed there.

Matthew Leeds 23304b8c15 lib/repo-refs: Fix resolving collection-refs
My last commit "lib/repo-refs: Resolve collection-refs in-memory and in
parent repos" changed ostree_repo_resolve_collection_ref() to check the
in-memory set of refs *after* failing to find the ref on disk but that's
not what we want. We want to use the in-memory set of refs first,
because those are the most up to date commits, and then fall back to the
on-disk repo and finally fall back to checking any parent repo. This
commit makes such a change to the order of operations, which is
consistent with how ostree_repo_resolve_rev() works.

Aside from this change being logical, it also fixes some unit test
failures on an unmerged branch of flatpak:

Matthew Leeds c9725d0bef lib/repo-pull: Allow the keyring remote to be overridden
Currently the P2P code requires you to trust every remote you have
configured to the same extent, because a remote controlled by a
malicious actor can serve updates to refs (such as Flatpak apps)
installed from other remotes.[1] The way this attack would play out is
that the malicious remote would deploy the same collection ID as the
victim remote, and would then be able to serve updates for it.

One possible remedy would be to make it an error to configure remotes
such that two have the same collection ID but differing GPG keys. I
attempted to do that in Flatpak[2] but it proved difficult because it is
valid to configure two remotes with the same collection ID, and they may
then each want to update their keyrings which wouldn't happen
atomically.

Another potential solution I've considered is to add a `trusted-remotes`
option to ostree_repo_find_remotes_async() which would dictate which
keyring to use when pulling each ref. However the
ostree_repo_finder_resolve_async() API would still remain vulnerable,
and changing that would require rewriting a large chunk of libostree's
P2P support.

So this commit represents a third attempt at mitigating this security
hole, namely to have the client specify which remote to use for GPG
verification at pull time. This way the pull will fail if the commits
are signed with anything other than the keys we actually trust to serve
updates.

This is implemented as an option "ref-keyring-map" for
ostree_repo_pull_from_remotes_async() and
ostree_repo_pull_with_options() which dictates the remote to be used for
GPG verification of each collection-ref. I think specifying a keyring
remote for each ref is better than specifying a remote for each
OstreeRepoFinderResult, because there are some edge cases where a result
could serve updates to refs which were installed from more than one
remote.

The PR to make Flatpak use this new option is here[3].

In Silverblue right now, the boot menu title looks like this:

    Fedora 29.20190301.0 (Workstation Edition) 29.20190301.0 (ostree)

This is because RPM-OSTree's `mutate-os-release` feature is enabled,
which injects the OSTree version string directly into `VERSION` and

Robert Fairley 21ebc7d21e Add sysroot.bootloader repo config key
The sysroot.bootloader key configures the bootloader
that OSTree uses when deploying a sysroot. Having this key
allows specifying behavior not to use the default bootloader
backend code, which is preferable when creating a first
deployment from the sysroot (#1774).

As of now, the key can take the values "auto" or "none". If
the key is not given, the value defaults to "auto".

"auto" causes _ostree_sysroot_query_bootloader() to be used
when writing a new deployment, which is the original behavior
that dynamically detects which bootloader to use.

"none" avoids querying the bootloader dynamically. The BLS
config fragments are still written to
sysroot/boot/loader/entries for use by higher-level software.

More values can be supported in future to specify a single
bootloader, different behavior for the bootloader code, or
a list of bootloaders to try.

Matthew Leeds 77f91d6c6b lib/repo-refs: Resolve collection-refs in-memory and in parent repos
Currently the behavior of ostree_repo_resolve_rev() is that it tries to
resolve a ref to a commit by checking the refs/ directories, but also by
checking for in-memory ref-checksum pairs which are part of an
in-progress transaction and also by checking the parent repo if one
exists. Currently ostree_repo_resolve_collection_ref() only checks the
refs/ directories, so this commit makes its behavior analagous since it
is the analagous API which supports collection-refs.

The impetus for this was that currently Flatpak uses
ostree_repo_resolve_rev() to load a commit after doing a P2P pull in
flatpak_dir_do_resolve_p2p_refs(), but that assumes the ref came from
the same remote that originally provided it, which might not be the case
if more than one remote has the same collection ID configured. And
changing Flatpak to use ostree_repo_resolve_collection_ref() doesn't
work without this patch.

Umang Jain 963395217a lib/repo-commit: Relax min-free-space check in prepare_transaction()
We want a case where we can disable the min-free-space check. Initially,
it felt like to add a OSTREE_REPO_PULL_FLAGS_DISABLE_FREE_SPACE_CHECK but
the problem is prepare_transaction() does not have a OstreeRepoPullFlags
parameter which we can parse right here. On top of it, prepare_transaction()
enforces min-free-space check and won't let the transaction proceed if
the check failed.

This is pretty bad in conjunction with "inherit-transaction" as what
Flatpak uses. There is no way to disable this check unless we remove
it altogether from prepare_transaction.

This issue came out to light when flatpak wasn't able to write metadata
after fetching from remote:

[uajain@localhost ~]$ flatpak remote-info flathub org.kde.Platform//5.9
error: min-free-space-size 500MB would be exceeded

Metadata objects helps in housekeeping and restricting them means
restricting crucial UX (like search, new updates) functionalities
in clients like gnome-software. The error banners originated from
these issues are also abrupt and not much helpful to the user. This
is the specific instance of the issue this patches tries to address.

Matthew Leeds 1d6347fe97 lib/repo-pull: Disable LAN updates by default
This commit disables searching on the local network for refs, unless
explicitly requested by the user either by changing the value of the
"core.repo-finders" config option, or by passing an OstreeRepoFinderAvahi to
ostree_repo_find_remotes_async() / ostree_repo_finder_resolve_async(),
or by specifying "lan" in the --finders option of the find-remotes
command.

The primary reason for this is that ostree_repo_find_remotes_async()
takes about 40% longer to complete with the LAN finder enabled, and that
API is used widely (e.g. in every flatpak operation). It's also probable
that some users don't want ostree doing potentially unexpected traffic
on the local network, even though everything pulled from a peer is GPG
verified.

Flathub will soon deploy collection IDs to everyone[1] so these code
paths will soon see a lot more use and that's why this change is being
made now.

Endless is the only potential user of the LAN updates feature, and we
can revert this patch on our fork of ostree. For it to be used outside
Endless OS we will need to upstream eos-updater-avahi and
eos-update-server into ostree.

Matthew Leeds 3956fc885b Allow disabling pulling from LAN/USB/Internet
Currently libostree essentially has two modes when it's pulling refs:
the "legacy" code paths pull only from the Internet, and the code paths
that are aware of collection IDs try to pull from the Internet, the
local network, and mounted filesystems (such as USB drives). The problem
is that while we eventually want to migrate everyone to using collection
IDs, we don't want to force checking LAN and USB sources if the user
just wants to pull from the Internet, since the LAN/USB code paths can
have privacy[1], security[2], and performance[3] implications.

So this commit implements a new repo config option called "repo-finders"
which can be configured to, for example, "config;lan;mount;" to check
all three sources or "config;mount;" to disable searching the LAN. The
set of values mirror those used for the --finders option of the
find-remotes command. This configuration affects pulls in three places:
1. the ostree_repo_find_remotes_async() API, regardless of whether or
not the user of the API provided a list of OstreeRepoFinders
2. the ostree_repo_finder_resolve_async() /
ostree_repo_finder_resolve_all_async() API
3. the find-remotes command

This feature is especially important right now since we soon want to
have Flathub publish a metadata key which will have Flatpak clients
update the remote config to add a collection ID.[4]

This effectively fixes https://github.com/flatpak/flatpak/issues/1863
but I'll patch Flatpak too, so it doesn't pass finders to libostree only
to then have them be removed.

  complete, having the LAN finder enabled slows down that step of the
  pull process by about 40%. See also

Jonathan Lebon a4a49724d6 ostree-prepare-root.service: Run earlier in initrd
Previously, we were preparing the root very late in the boot process;
right before we switch root. The issue with that is that most services
in the initrd that run `After=initrd-root-fs.target` expect that
`/sysroot` already points to the rootfs we'll be pivoting to. Running
this late violates that assumption.

This patch fixes this by making `ostree-prepare-root.service` instead
run right after `sysroot.mount` (the physical sysroot mounted by
systemd) but still before `initrd-root-fs.target` (which is the target
signalling that `/sysroot` is now valid and ready).

This should make it easier to integrate OSTree with other initrd
services such as Ignition.

The idea is that if the process is running as root, it can change
ownership of newly written files to match the owner of the repo.
Unfortunately, it currently applies in the other direction, too - a
non-root user writing to a root owned repository. If the repo is
writable by the user but owned by root, it can still create files and
directories there, but it can't change ownership of them.

Colin Walters 673cacd633 repo: Add a checkout option to not hardlink zero-sized files
In rpm-ostree we've hit a few cases where hardlinking zero-sized
files causes us problems.  The most prominent is lock files in
`/usr/etc`, such as `/usr/etc/selinux/semanage.LOCK`.  If there
are two zero-sized lock files to grab, but they're hardlinked,
then locking will fail.

Another case here is if one is using ostree inside a container
and don't have access to FUSE (i.e. `rofiles-fuse`), then the
ostree hardlinking can cause files that aren't ordinarily hardlinked
to become so, and mutation of one mutates all.  An example where
this is concerning is Python `__init__.py` files.

Now, these lock files should clearly not be in the tree to begin
with, but - we're not gaining a huge amount by hardlinking these
files either, so let's add an option to disable it.

There are use cases for libostree as a local content store
for content derived or delivered via other mechanisms (e.g. OCI
images, RPMs, etc.).  rpm-ostree today imports RPMs into OSTree
branches, and puts the RPM header value as commit metadata.
Some of these can be quite large because the header includes
permissions for each file.  Similarly, some OCI metadata is large.

Since there's no security issues with this, support committing
such content.

We still by default limit the size of metadata fetches, although

Matthew Leeds 9a06c5409e create-usb: Add a --commit option
Currently on Endless OS, the OSTree ref for the operating system is
something like os/eos/amd64/eos3, so that's what gets passed to `ostree
create-usb` when copying the OS to a USB drive (for offline updates).
However, when eos-updater checks for updates it pulls the metadata for a
candidate commit and in so doing updates that eos3 ref to point to the
partial commit being examined as a potential update rather than the
deployed commit. This causes `ostree create-usb` to fail with an error
like "No such metadata object
7fb045cb2d1f1f3a81bfc157c6128ff443eb56350315b9536bdb56aee0659863.dirtree".

OSTree creates deployment refs that look like "ostree/1/1/0" to maintain
a pointer to the deployed commit, but create-usb can't use these because
it shows up in the summary as just a ref, not a collection-ref.

So this commit adds a --commit option to the create-usb command, so we
can use the appropriate ref but copy the deployed commit rather than a
(potentially partial) update commit.

Matthew Leeds fc357adb79 create-usb: Always use archive mode
Change the create-usb command so that it always creates the destination
repository using the "archive" mode, rather than using archive mode when
xattrs aren't supported and bare-user otherwise. This has a few
advantages:

1. The archive mode works with FAT filesystems, which is what most
USB drives are, and which doesn't support xattrs.

2. At least in some quick testing I did, archive mode is about
twice as performant as bare-user mode, in terms of how long it takes for
the create-usb command to complete.

3. This ensures that a tool can safely change the permissions on
".ostree/repo" and subdirectories after create-usb completes, which is
important for Endless since otherwise you can't use `ostree create-usb`
as root and then `flatpak create-usb` as a non-root user on the same USB
drive (or in other words copy OS updates and apps to the same USB).

Matthew Leeds fc84fb402c lib/repo: Define a metadata key, ostree.deploy-collection-id
This commit defines a metadata key that tells clients to update their
remote config to add a collection ID. This functionality is currently
implemented in Flatpak for the key "xa.collection-id", but there are two
good reasons for moving the key to OSTree:

1) Servers such as Flathub shouldn't set xa.collection-id in their
metadata now or in the medium term future, because many users are still
using old versions of Flatpak and OSTree[1] which would hit various
bugs[2][3][4] on the P2P code paths that are enabled by collection IDs.
Defining a new key means that only clients running recent
(as-yet-unreleased) versions of Flatpak and OSTree will pay attention to
it and deploy the collection ID, leaving the users on old versions
unaffected.

2) OSTree is as "invested" in collection IDs as Flatpak, so there's no
reason the key should be defined in Flatpak rather than here. According
to Philip Withnall, the reason the key was put in Flatpak originally was
that at the time there was uncertainty about tying OSTree to collection
IDs.

Matthew Leeds e4e6d85ea4 avahi: Be robust to missing refs in peer summaries
In the OstreeRepoFinderAvahi implementation,
ostree_avahi_service_build_repo_finder_result() is where the DNS-SD
records are processed and turned into OstreeRepoFinderResult objects.
Each result object is supposed to have a hash table mapping refs to
checksums, so this is accomplished by first adding a placeholder (a ref
mapping to a NULL checksum) for each ref matched by the bloom filter,
and later filling in the checksums using the remote's summary file,
which happens in get_checksums(). The problem is that there's no
guarantee all the checksums will be resolved (non-NULL), so the
ostree_repo_finder_result_new() call then hits an assertion failure in
is_valid_collection_ref_map() leading to a crash (in the case that one
or more refs had NULL checksums).

There are at least two situations where the ref checksum might not be
found in the peer remote's summary file:
1) The bloom filter match was a false positive. This is going to happen
sometimes by design.
2) The peer remote's summary is out of sync with its DNS-SD records.
This shouldn't normally happen but it's still good to be robust to the
possibility; in Endless OS nothing guarantees the atomicity of updating
the summary and DNS-SD records.

This commit changes libostree to be robust to the possibility of refs
missing from the peer remote's summary, by removing any that still have
a NULL checksum associated with them after the summary has been fetched
and processed.

The other OstreeRepoFinder implementations don't have this issue because
they use summary files directly and therefore always have access to the
checksum.

Umang Jain 3814d075cb lib/repo: Ensure min-free-space* config value doesn't overflow
when converted to bytes

In a subsequent commit, we add a public API to read the value of
min-free-space-* value in bytes. The value for free space check
is enforced in terms of block size instead of bytes. Therefore,
for consistency we check while preparing the transaction that the
value doesn't overflow when converted to bytes.

Felix Krull 74bdf7e173 lib/grub2: Support Debian-style grub.cfg path
Debian and Debian-derived systems have their GRUB configuration file in
/boot/grub/grub.cfg, rather than /boot/grub2/grub.cfg. Detecting this
file is necessary to correctly generate GRUB boot configuration on
Debian systems.

Sinny Kumari dde3f1c0fb src/ostree: Add --group option to ostree config
Fetching value from a repo config using 'ostree config
get SECTIONNAME.KEYNAME' didn't work in some cases like
when having dots in Group Name entry.
As per Desktop entry file specification, Group Name
may contain all ASCII characters except for [ and ]
and control characters.
Link - https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-1.1.html

Having --group option will help user to clearly specify
Group Name and get desired result.

It also adds test for ostree config get|set and bash
completion for --group option

Philip Withnall e7305bbc8a lib/repo-pull: Prefer object pull over from-scratch delta if ref exists
If a ref already exists, we are likely only a few commits behind the
current head of the ref, so it is probably better for bandwidth
consumption to pull the individual objects rather than the from-scratch
delta.

Will Thompson 2b19869307 repo: remove outdated note from write_config() docs
Since 9dc6ddce08 it has not been true that
'new_config' was simply ref'd: it's serialized, and then re-parsed into
a new GKeyFile.

Dan Nicholson 4e6b13e8b6 repo: Add OSTREE_REPO_TEST_ERROR=invalid-cache env var
Add an invalid-cache test error flag to ensure that the code that checks
for and recovers from a corrupted summary cache is hit. This helps make
sure that the recovery path is actually used without resorting to
G_MESSAGES_DEBUG.

Dan Nicholson e5061f54d6 lib/pull: Fetch summary if cached version doesn't match signature
If for some reason the cached summary doesn't match the cached signature
then fetch the remote summary and verify again. Since commit c4c2b5eb
this is unlikely to happen since the summary will only be cached if it
matches the signature. However, if the summary cache has been corrupted
for any other reason then it's best to be safe and fetch the remote
summary again.

This is essentially the corollary to c4c2b5eb. Where that commit helps
you from getting into the corrupted summary cache in the first place,
this helps you get out of it. Without this the client can get wedged
until a prune or the remote server republishes the summary.
