[bug#69131] [PATCH 2/2] gnu: podman: Update to 4.9.3.

[Skyler Ferris via Guix-patches via]

Hi Tomas,

Thanks for submitting this patch! I am adding some review notes to this 
issue in hopes of making the process more efficient for the committer. I 
noticed that `guix style` applies some minor changes to the definition 
of passt which should ideally be followed, but I don't expect that this 
would hold up the commit (and I'm not sure if it would be appropriate or 
intrusive to add a new patch to this thread with the style changes 
applied). Everything else looks good! I will add a couple more messages 
to this thread which contain full notes of items I reviewed, for 
transparency and clarity. Please let me know if there is anything I 
could do to improve my review process!

Regards,
Skyler

Only thing I would maybe mention is that as far as I can tell, I did not
receive any emails regarding your comments.  I am not sure if that is
just how debbugs works, but if I did not open the bug for unrelated
reasons, I would have never noticed you commented.

Have a nice day,
Tomas Volf

"Update podman" review notes:

The following checklist is based on the items listed in the manual (22.7 
"Submitting Patches"). Each checklist item may have one of the following 
statuses:

C: Commitable. This item looks as expected for a final commit.
CC: Commitable with Context. Like commitable, but some notes have been 
added providing context about anything notable or unusual. These notes 
are provided for transparency or to set expectations for the committer 
and should not be interpreted as meaning that I object to the patch.
MR: Minor Repair. There is something about the patch which I think 
should ideally be changed, but I do not think that the commit should be 
held up for this reason alone.
A: Attention. Something in the patch needs attention from the author, 
the committer, or both. Resolving the matter may or may not require a 
change to the patch.
Blank: I did not review this aspect of the patch.

# Applies Cleanly
Git reported that there were some "whitespace errors" due to spaces 
before tabs. This is because the commit includes a new patch and the 
patch applies to a file that uses tabs. The diff format requires that a 
space appears before the tabs, so this error is erroneous.

# Cryptographic hash
A key with a fingerprint of 968479a1aff927e37d1a566bb5690eeebb952194 
verified a checkout that hashes to the same value as found in the 
package. This key is listed on the Ubuntu keyserver 
(https://keyserver.ubuntu.com/pks/lookup?search=B5690EEEBB952194&fingerprint=on&op=index) 
with two signatures from other keys. One of them is a key that only has 
a self-signature, the other has a large number of other signatures and 
claims to belong to Andy Brody 
(https://keyserver.ubuntu.com/pks/lookup?op=vindex&search=0xc7090b1a5f57cdc5). 
The key was not found on the OpenPGP keyserver. The only UID attached to 
the key is "GitHub <noreply@github.com>", implying that the GitHub 
server is ultimately responsible for maintaining source integrity.

# guix lint output
Guix lint reports 2 issues neither of which require action.

It states that the new version is "probably vulnerable to 
CVE-2022-2989". However, the discussion at 
https://bugzilla.redhat.com/show_bug.cgi?id=2121445 indicates that fix 
is implemented by 
https://github.com/containers/podman/pull/15696/commits/21540161f20daffd884eba99b2cc31373c9a0ec4. 
My copy of the checkout contains commit 
d82a41687e614d9ac8b2d169dee47fe226835e4c which has an identical diff.

It also states that line 396 is too long, but this is due to a long 
string which consists of a single "word" (a path).

# guix style output
The tool wants to change the formatting of the majority of lines in this 
package, which were not changed in this patch, leading to a much larger 
diff than what has been submitted.

# Container with minimal inputs
I ran the following command:

```
$ ./pre-inst-env guix shell -C podman -- podman ps
```

This caused podman to print 2 warnings and 1 error in addition to the 
header line for containers (as I do not have any containers on my 
system, I expected the remaining output to be blank). The warnings & 
error were related to "/" not being a shared mount (it's not) and 
operating in rootless mode (the output made sense based on rootless.md 
in the root of the repository).

# Dependent packages
There is one dependent package, distrobox, which continues to build 
successfully after applying this patch.

# Patch Application
The copyright statement in the first patch does not apply cleanly 
because commit 6002e9e7711136373de5a6325769e9c7d11032c9 recently added 
it already, but git successfully processed that diff after manually 
deleting the chunk from the patch.

# Cryptographic Signatures
I was not able to locate signatures for either the source tarball or the 
git commits.

# Guix Lint Output
The linter printed two notes, one that the 'generic-html' updater failed 
to find upstream releases and another indicated that archives are not 
available from either Software Heritage or Disarchive. As I understand 
it, these issues issues should not block the package. Not every package 
has an automatic updater (though it would be nice if they did) and the 
release page for this project is atypical. The 'archival' section in the 
"Invoking 'guix lint'" chapter (9.8) indicates that the Software 
Heritage will pick up the source at some point in the future.

# Guix Style output (Minor repair)
The tool made some reasonable-looking changes. I'm not sure if it would 
be appropriate for me to add a new patch to this thread that applies 
these changes.

# Runs in a container with minimal inputs
This package wants to use QEMU, and my machine is already a Xen guest. I 
know that there are some complications when it comes to nested 
virtualization. The demo script (at #$output/share/doc/passt/demo.sh) 
did not "just work" for me, but it's not clear to me that this is a 
problem with the package. I tried running it with the following:

```
$ # Extra inputs are for the shell script
$ ./pre-inst-env guix shell -C iproute2 coreutils util-linux-with-udev 
passd
[env]$ 
/gnu/store/wgzlv2chrxmk4y4m4fxx8g7x0z59cb98-passt-2023_12_30.f091893/share/doc/passt/demo.sh

I sent a v2 with some of the style changes applied.  It seems that
across guix the more common approach is to put (modify-phases) under the
#:phases keyword, and I prefer it.

In general I do not believe what `guix style' did to the (arguments) let
to more readable code, so I left it as it was.

I did adjust the (source) and (description) though.

I tested the pasta binary instead using podman (--network=pasta), since
it was the reason I added this package in the first place.  It worked.

Applied.  I took the liberty to rename the patch to something shorter,
in accordance with ‘guix lint’.

Thanks!
