Thank you for sharing (what seems to be) a technical limitation of
Debbugs.  Could you please explain what the consequences of the above
are?  Specifically, how does the rewriting of above headers affect the
contributors' workflow?

It seems (based on above) that "patchwork" can co-exist with debbugs.
Is that also the case with b4/lei?  Specifically, are the
users/reviewers able to benefit from using the above tools at present?
Or are there some reasons (over and above their lack of familiarity with
the above tools) that would prevent them from doing so?

Every reply to one of your mails ends up creating a new thread in my
mail client, because the In-Reply-To chain ends up being broken.

They both can co-exist with debbugs, and for now the patchwork instance
of QA is not usable for status tracking (because it is not meant to be
used as such for now).  One can already use both of them, but using both
supercedes debbugs, and gets rid of its limitations.  I've been using
b4/lei with the yhetil public-inbox instance, with piem.el as an
interface, and it's really useful.  With a properly configured b4, one
could simply run `b4 shazam some-msg-id` and it would automatically
apply the corresponding patchset.

And before you ask why I'm so intent on getting rid of Debbugs, I
believe that mailing lists should be just that, mailing lists.
Anything that tries to rewrite incoming mail is asking for trouble
nowadays.

Ah, whoops, I thought you were asking about the Message-ID problem I
also reported to you, not my above paragraph, sorry.

One big consequence: mails containing patches can often have bogus From:
headers, which are used by git for the commit author.  Thus, we end up
with commits in the repo authored by eg. "Josselin Poiret via
Guix-patches via <guix-patches@gnu.org>".  We added a default gitconfig
entry that also puts the From: in the body of the message so that it is
not corrupted to circumvent this.

The fact that you have to wait for Debbugs's response after the first
mail to get the proper mail to reply to means that we can't automate
sending whole patchsets, and have to resort to hacks like the CLI `mumi`
tool uses.  I can't just send a patchset and be done with it, I have to
wait a couple minutes.

Well, that is a conflict between guix policies/practices and
debbugs.

Debbugs handles sending multiple patches in a single email just fine,
which can be done on the initial submission.

That has downsides with regards to threading, but given all the current
limitations, I wonder if the downsides of having to wait for the initial
bug number to land are worth the cost of having to implement a
user-interface tool (mumi CLI) to workaround it.

That said, the tool already exists... but not everyone is aware of it or
for whatever reason is not necesarily using it.

Are there other downsides to allowing a multiple patches in a single
email?

Ideally the technology would fit whatever practicies guix would like to
implement... but then we have what we have right now.

Could a modified version of Debbugs group submissions by Message-IDs
instead of bug numbers? Would it allow subsequent emails to be sent
before the initial message was acknowledged?

Hi Josselin, what do you mean?  Each email has its own message id, so
how would you group them?

To me, an ideal solution would be a service that

1) Doesn't modify any incoming mail;
2) Provides a way to look-up the bugs related to a thread and their
status, preferably using Message-ID, so that it can be used in
conjunction with other mail-based tools without disturbing them.

Your proposed modification would be a first step in that direction, but
would still not solve 1 and 2 perfectly.

We could use a new email header (say X-GNU-PR-Bug) for the grouping,
whose value would be a unique random id, generated (automatically) by
the patchset sender?

We'd have the guarantee that two different bugs won't have the same
X-GNU-PR-Bug value, and we'd be able to send the patches in a more
automated way.

What if those bug reports were available for your consumption via IMAP
folders or NNTP news groups whose idenfier is the initial Message-Id?

Why “in addition” though?  As long as Debbugs is modifying mails on the
MLs it's being troublesome.

That might introduce too much complexity: what we probably want is just
a bug tracker that maps bug IDs to Message-IDs, then consumers just use
whatever tool they'd prefer, be it browsing a public-inbox instance
through a browser, their local mail, etc.  Debbugs could include a
public-inbox instance, or just interact with one (preferred so that
efforts are not duplicated).  Just having the header part of
e.g. bugzilla would be nice, maybe with a log of mails that caused a
state change, and a list of relevant threads (there could be multiple,
for example if there are multiple versions of a patchset, or for the bug
report and the ensuing fix).

P.S. With a bug tracker, our discussion could be off-list. It would
reduce the reading burden for folks who do not care about the topic.

See e.g. [1], where my reply should have the subject “Re: bug#nnnn ...”,
but Debbugs doesn't like that and so changes it to just “bug#nnn ...”.
This modification in turn invalidates DMARC because From is protected,
so it *has* to rewrite it to another domain to make it pass DMARC.

In 889a6204f8 (doc: Add some guidelines for reviewing, 2023-11-07),
Maxim added some b4 configuration to Guix's etc/git/gitconfig that
points at yhetil.org.  With that setup, running 'b4 shazam MESSAGE-ID'
from a Guix checkout should work.

You may have just be asking about configuring 'b4 shazam', but if you
(or others) are interested in configuring piem, read on :)


piem setup and use
==================

For piem, you need some custom setup in your Emacs config.

  https://docs.kyleam.com/piem/Registering-inboxes.html

piem-inboxes contains entries that provide info to help piem map from a
message (say in Notmuch or Gnus) to a public-inbox URL and to a local
checkout of the repo.

  (setq piem-inboxes
        '(("guix"
           :coderepo "/path/to/your/clone/of/guix/"
           :url "https://yhetil.org/guix/"
           :listid "bug-guix.gnu.org")))

Further setup depends on how (in Emacs) you read your messages.

  https://docs.kyleam.com/piem/Enabling-integration-libraries.html

For example, a Notmuch user would enable piem-notmuch-mode:

  (piem-notmuch-mode 1)

Or a debbugs.el user would enable piem-debbugs-mode (contributed by
Jelle Licht).  You can enable more than one integration library.

Once that's set up, the main entry point to b4 is the piem-b4-am
transient.  That transient in turn has the main command of interest,
piem-b4-am-from-mid.

  https://docs.kyleam.com/piem/Using-b4-to-apply-patches.html

Calling piem-b4-am-from-mid from, say, a Notmuch message with a patch
series will prepare the "am-ready" series, prompt you for the name of a
branch to create, and apply the series with 'git am' to the configured
repo.


piem-b4-am-from-mid vs b4 shazam
================================

piem-b4-am-from-mid (from Emacs) and 'b4 shazam' (from the shell
visiting Guix repo) are similar in spirit: use 'b4 am' to prepare an
am-ready mbox from a thread's full mbox and then use 'git am' apply it
to a repo.  A key difference is that, with piem, you start off in some
non-repository Emacs buffer containing a message and then piem knows how
to get to the repository (using the config above).

As a side note: 'b4 shazam' didn't exist when I wrote piem's b4
integration.  At some point, I plan to add 'b4 shazam' support to piem,
similar to how there is a piem command (piem-b4-am-ready-from-mid)
that's a direct interface to 'b4 am', without the extra handling of
piem-b4-am-from-mid.  This will allow callers that prefer to use shazam
invoke it from Emacs rather than the command line.


lei
===

There's also mention upthread of lei.  I don't think you're asking about
configuring that, but fwiw that's public-inbox's local command-line
client.  I gave a short (and incomplete) description of it here:

  https://yhetil.org/guix-devel/87a6izsoio.fsf@kyleam.com

piem currently has some basic support for lei, focused on searching
public-inbox instances and displaying the results in Emacs.

Indeed!  It should perhaps be more prominently documented, probably as
an new 'Reviewing patch work flows' section in the Guix Cookbook that
could be linked from our already lengthy Contributions section.

'b4 shazam' is probably the most trouble-free way to apply patches; it
even selects the latest revision it finds in the issue thread.  To make
finding a message-id easier, I've also recently added a 'Copy
Message-ID' button to the Mumi interface; try it visiting any issue,
e.g. <https://issues.guix.gnu.org/68990>.  The message-id of any message
can be easily copied to your clipboard via the new button.  From your
Guix checkout, you'd then run:

--8<---------------cut here---------------start------------->8---

I also agree! :-) What appears to me “difficult” is that most of the
tools as Email client are poorly supporting Message-ID.

For instance, debbugs.el (Gnus).  To my knowledge, there is not easy way
to get the Message-ID when reading an article (bug/patch) from Debbugs.
There is other means for applying patches.  But still each time appears
to me weird. :-)

So thanks for this Mumi addition!

I think b4's ML is more active than the GitHub issues, I have already

I don't agree (both Gwene + Gnus or Emacs Debbugs work perfectly too and
allow to apply a range of n patches at once) but I don't think there is
a need for competition here, it's good that we have several tools.

The author of Debbugs.el, Michael Albinus, said this was likely the best
solution.

To request a feature in Debbugs.el, please file a bug against the
"debbugs.gnu.org" package on debbugs.gnu.org. Thanks!

To be clear, my message [1] was not to report a “bug” or request for a
“feature” in debbugs.el.  My message was:

                          What appears to me “difficult” is that most of the
        tools as Email client are poorly supporting Message-ID.

        For instance,

And I took as one example the venerable debbugs.el for making my point:
most of the tools that deal with Emails poorly support one key of Email
heart: Message-ID.

Personally, I rely on the cool piem.el and some custom Emacs lisp
helpers, then for dealing with complex patch or bug thread, I inject and
process them with notmuch.el. :-)

Therefore, open a feature request is low on my list of TODO. ;-)

Yes for sure it is good to have several tools.  And the ones you like. :-)

No one is advocating to make ’b4 shazam’ THE only one tool.

Instead, I agree with Maxim that exposing Message-ID and relying on ’b4
shazam’ is the most trouble-free and config-less way to apply patches.

And what about Summary buffer?

Well, it makes my point, no? :-)

For sure the Message-ID is there and for sure it is possible to extract
it.  However, it appears to me weird that it is not built-in.  I mean
Message-ID is one of the heart of Emails, and Debbugs is just Emails,
but debbugs.el does not provide a built-in access to it.

Yes it does provide a built-in access, as I showed you.  Just search for

Somehow, the reader will judge if Message-ID is smoothly supported. :-)

I didn't reply to this, but to your debbugs.el (gnus) example,
explaining how Message-ID was well supported.

i regularly meet this most unfortunate attitude in the GNU circles, where oldtimers dismiss any discussion of friendlier defaults for newcomers with the "argument" that it's configurable, and therefore it's a non-issue.

I usually used C-u g to see the message source, then regexp-searched for
^Message-ID, but that's not exactly convenient.

Agreed.  A "does-not-apply" tag would be helpful.  This tag would be
explicitly applied, either by the QA mechanism or a reviewer.

Assuming there aren't any objections to these tags, what are the next
steps?  If my understanding of Debbugs Usertags is correct it seems we
can simply start using them?  Though noting the above in the manual
would be helpful.  However, that still leaves open the issue of how the
automated setting of tags is accomplished.

Thoughts?

Would it makes sense to have a "does-not-apply" tag too?

I believe that would help sorting old those old patches that don't apply

I think it would be useful (at least for me) if I browse a list of
patches that I want to review, to document why a review can't be done.

Also, so that other people won't try to apply it.

It would be great that QA does that job, I imagine when it does it it
can also add that tag.

There's the filter issues form which allows finding patches which can't
be applied:

  https://qa.guix.gnu.org/patches?failed-to-apply-patches=on

I think QA tagging issues might be useful for people to benefit from
that data in other places, and should be possible, it just needs QA to
send emails I think.

It seems on the [dev manual] we already have "reviewed-looks-good"
documented.  Thus, I'd like to propose the below *mutually exclusive*
Debbugs tag set:

- "not-yet-reviewed" :: automatically set for all submissions
- "reviewed-needs-fix" :: set explicitly by the reviewer
- "needs-another-review" :: automatically set if there's a revised
  patch, unless "not-yet-reviewed" (in which case no change)
- "reviewed-looks-good" :: set explicitly by the reviewer

In addition to the above, it might also help for there to be an
additional tag of "might-not-need-review" (or simpler,
"review-not-needed") which gets automatically set, provided we implement
a way to label some changes (for some packages) as being "trivial enough
that they're okay as long as build succeeds".

On a related note, is it possible for a reviewer who isn't a committer
to set debbugs tags?

[dev manual]: <https://guix.gnu.org/en/manual/devel/en/html_node/Debbugs-Usertags.html>

In addition to documenting the tags in the "Debbugs Usertags" section of
the manual, it would help for there to be a "howto" which focuses more
on the transition between the tags (i.e., the contribution workflow).

I believe the state tracking could be improved, and have given some
concrete suggestions in another thread.  However, I believe these are
orthogonal to whether or not the workflow is "mail-based".

For clarity, within Emacs' Debbugs interface I can use a combination of
tags and marks to highlight the issues of interest.

I believe the ease or not of this would depend on the email client of

This is probably an important issue if true.  To clarify, in "those not
using [E]macs" are you considering developers using other email clients
such as Alpine, Mutt etc?

>      o It does not tell which issues are stale

What does "stale" mean to you?  Do you mean something other than
Debbugs' notion of staleness?

In an attempt to focus the discussion on the specific features, it seems
if, in addition to improved state tracking, the below were available it
might help (to varying degrees depending on the user):

1. Some tooling that helps in "checking out" a specific revision of a
   patch series.  I don't know if this already exists, given my relative
   inexperience with Debbugs.

2. An ability to leave comments inline on
   <https://issues.guix.gnu.org/>.

While "forges" provide both of the above in some form, they may not be
the only way to accomplish the above.

First off, I'm sorry I write so much today. For a project the size of

None of the above. I believe committers should commit only changes they
are comfortable with. Otherwise, they should leave a bug to folks with
more experience, perhaps tagging it along the way.

I think there should be a hundred people who do nothing but add new
packages. They would free up valuable capacity for the people
experienced with build systems, Guix services and their configuration,
the user interface, the daemon, cross-compilation and other more
difficult speciality areas.

Kind regards

Re: Guix Days: Patch flow discussion

[Andy Tai]

Hi, this is a sugestion on guix patches:

Other GNU/Linux distributions often have fixed maintainers (or
packagers) for specific packages.
While that model may not apply directly to the Guix project as anyone
can send in patches for anything in the git repo, maybe one thing the
Guix project can do is to recognize if someone has sent in patches for
specific projects many times in the past, then that means the person
has knowledge, interest, familiarity and expertise about this package
and the reviewers can spend minimal time of his/her future patches for
the same package(s).

Thus this creates kind of pseudo package maintainer in Guix, reducing
workload of reviewers and speeding up package update.

Guix can have a text file in the Guix repo recording say someone who
is "responsible" or is a "pseudo packager" for specific packages,
which the committers can refer to to allow quick processing of
patches.  This does not mean the person responsible for certain
package has git commit access but just to allow a quick path for patch
processing by the commiters of certain patches from the familiar
person.

Of course others can still send in patches for these packages already
with pseudo packagers.

We have exactly this:
https://git.savannah.gnu.org/cgit/guix.git/tree/etc/teams.scm

And it's even better: those people automatically receive an email if you
use git-send-email to send a patch about their associated files.

Re: Guix Days: Patch flow discussion

[Andy Tai]

What I proposed is in terms of the scope of a single package. The
teams cover much larger and broader scope, like Gnome or Python.

I could be mistaken, but I believe this does happen today at least some

1. this never happens today and thus, should happen some times when

Just to reply to this part, there were a variety of views on what the correct 
balance was between teaching someone and fixing issues so that a contributors 
patch was applied without them having to make further efforts. The general 
opinion seemed to be, that it was better to fix small issues and commit the 
change for new users, so they had the satisfaction of their contribution making 
it into the repository. One proposal was to do the 'fix', and to then reply 
back to the bug with a diff - showing what was done.

It's not only installing and testing the patches, but also

  * when has this issue/patch been worked on last - is somebody
    currently working on it
  * what issue/patches I started to review?
  * commenting on code requires to download the patch - strip out parts
    which are okay, comment, then mail the commented code to the correct

      o It does not tell what issues/patches I've been working on
        already - and waiting for a reply
      o It does not tell which issues are stale

Anyhow, all of this has been discussed several times already. And as 
long as vocal (and active :-) members of the community insist on being

forges — this situation will not change.

While I agree with your assessment of what's missing in this workflow,
I'm not sure I know of any e-mail-capable forges that resolve those
particular pain points…  People often think that eg. sr.ht works better
for this, but I don't think the sr.ht MLs have any more structure than
what we have.  For smaller projects, it works okay, but once you get to
the scale of something like Guix, it doesn't offer anything more.

One thing I would like to get rid of though is debbugs.  It causes a lot
of pain for everyone, eg. when sending patchsets, it completely breaks
modern email because it insists on rewriting DMARC-protected headers,
thus needing to also rewrite "From:" to avoid DMARC errors.

I've been following the Linux kernel development a bit closer this past
year, and while there are things that need to improve (like knowing the
status of a patchset in a maintainer's tree), they at least have a lot
of tools that I think we should adopt more broadly:

b4/lei is a nice example (we already have yhetil.org as a back-end, but
maybe a more blessed one would be better) of a tool that lets you
completely automate applying a patchset to a branch.

patchwork is a nice tool to gather up and track patchsets, with status
indicators like "under review", "accepted", etc.  Chris already deploys
one as part of QA, more integration with it would be nice.

One advantage of this is that we would benefit from upstream's bigger
user-base and dev time, and also from the fact that these tools are made
to work together (b4 can automatically mark patchsets as accepted)!

I think "auto-commit" is a bit too much, but tagging a patch as "can be
pushed" could make it easy for committers to find them and push them.

Ideally with debbugs tags.

(Patches that don't need review should be tagged as well.)

Agreed.  A reduction in the time between a patch (or patch revision)
submission and a review/reaction would be a positive change in my
opinion.

Are there current instances of "contributor can't work effectively"?  If
not, I propose that decisions concerning those situations be deferred
till we have actual instances to guide us.

Agreed.

I believe the below steps would help with the current situation, and
perhaps both should be pursued (among possibly others).

1. It would help to eliminate the need for review in certain kinds of
   patches.  Some version upgrades for a package $foo where there exists
   no package $bar that depends on $foo may fall in this category.  More
   generally, some "known to be safe with reasonable confidence" changes
   may be safe to be auto-committed without needing manual review.
   Recognizing such changes could be challenging, but we don't have to
   correctly label all such changes in order for this to be helpful.

2. It would help if it were easier for the community to be able to identify the next
   steps, given a patch submission.  It might help to (more?) clearly
   differentiate between the below states:
   - patch *needs review* (automatically set)
   - patch *needs revision* (set explicitly by the reviewer, say, by
     using a specific keyword in their email)
   - patch *needs followup review* (automatically set if there's a
     revised patch)
   - patch has a *satisfied reviewer* (set explicitly by the reviewer,
     say, by using a specific keyword in their email)

Maybe this encompasses the cases where the contributor sends a v1 and

Guix Days: Patch flow discussion

[Steve George]

Hi,

Our goal for the discussion:

	How do we double the number of patches that are *reviewed* and
	*applied* to Guix in the next six months?

Patch flow is a pipeline, to change it we could:

a. Increase the number of committers - more people to do the
work
b. Increase the efficiency of existing committers
c. Open the gates by decreasing the quality expected from patches

We essentially decided to focus our discussion on (b). We looked at
things that 'hinder' and 'help' patch review:


Hinders
========

- All our patch reviewers are volunteers doing it in their spare time.

- For a volunteer reviewing someone else's work is not very rewarding, 
most would prefer to use that precious time to scratch their own itch.

- Can feel like an Sisyphean task: no matter how many patches someone 
reviews there are more, exacerbated by the number of Guix packages.

- Sense of responsibility: the minute that a reviewer looks at the patch 
they are now stuck with it

- Repetitive and boring: often patches have minor issues, but it's the 
same sorts of issues time and time again.

- Risk of negative social interaction: having to tell someone that their 
patch is incorrect, or that their contribution cannot be used is 
difficult and draining. Some people felt it was better to say nothing, 
rather than to respond to a patch.


Helps
======

This led us to the focus on the fact that **reviewing and applying
patches can be different people**

We looked for ideas to create more reviewers, make reviewing easier and
more fun:


- Share in the work
--------------------

1. encourage new reviewers to step forward - making it more known that 
reviewing patches helps to get them applied. Anyone can review patches.

2. create directed 'how-to' documentation for reviewing and connect it 
to QA so that 'new reviewers' know what to do

3. create documentation about 'when' and 'how' it's appropriate to send 
a 'v2' version of a patch so that the QA system builds and accepts it. 
Sometimes, patches rot because non-committers don't want to be seen as 
'stealing' someone's work with a v2 patch - but making the small changes 
and resubmitting to QA is what is required.

4. Pay someone else to do it. Noted but out of scope.
5. Remove old packages overhead. Old untouched packages create mental 
overhead, and make the task of maintaining the repository in a good 
state more difficult. We could remove old 'untouched' packages and ones 
that no-longer compile. We have methods to hide and notify.


- Make it more fun
-------------------

1. do online sessions around reviews, some sprints or pairing - both 
social and a way to spread skills
2. find ways to recognise and appreciate reviewers - 'reviewer of the month'
3. make it a game - we could have a 'Guix London' vs 'Guix Paris' leader 
board for reviews. Make it a group goal 'can we beat januarys reviews 
number'
4. create some graphs / leaderboard so we know how many patches are 
being reviewed and we can recognise the contribution


- Automate it away
-------------------

1. Chris is continuing to try and automate away the boring work - 
general agreement in the group that QA has made a lot of difference.

2. general discussion about create a 'guix review' command (Nix has one) 
which would download a branch with the appropriate patch and build it 
locally. This is for instances where some adjustment is needed or to 
check a build. While this can be done today, it's a number of steps and 
quite involved.


Agreed Actions
==============

* [Chris]: continuing his work to improve QA automation. Implication was 
we'll need some reports / graphs - but these were not discussed in detail.

* [Futurile]: organise a **patch review online sessions**. To run every 
13 days (so it rotates through the week) - for 3 months to see if it has 
any traction. Co-ordinate with maintainers so that patches that are 
reviewed can be committed


Actions looking for someone - you?
====================================

* Carry forward the 'guix review' command idea

* Write an RFC and discuss the idea of removing older 'bit-rot' packages

* write 'how-to' documentation for reviews and when it's socially
acceptable to do a v2 patch. A checklist-like approach.


If you were in the discussion and I've misrepresented your point, or 
forgotten an important aspect please please reply and correct me.

Also, if you would like to help on any of the tasks please email back to 
the group so we can all co-ordinate.

Finally, thank-you to everyone who came along and put their shared brain 
power to the task - look forward to doing some patch reviews together 
online in the coming weeks!

Thanks,

Steve/Futurile

Hi George,

It's an important subject and, in my opinion, more important than any technical questions at this stage of the project.

However, I think the question assumes that all contributions should be accepted, and that the entire problem is that we are not accepting them efficiently enough. We should not unconsciously accept this assumption.

Guix can reject contributions, either in a general way (we don't want that type of thing in Guix), or due to specific reasons (the code is not idiomatic, the contributor can't work effectively with the rest of the group, etc).

And I believe that is fine and completely within the rights of the committers.
However, in my experience contributing, the issue is not that people explicitly
tell me to go away, but that the patches are just ignored.

I would say that the outcome (for any specific patch) from the proposed "review
session" can very well be patch just being closed, or tagged as "need-more-work"
(or whatever tag is Guix using).

In ideal world, there would always be *some* reaction from the project, even if
that reaction would be "we do not want this change".  Even if it would be just
an auto-close (for the "contributor can't work effectively..." case).

Or, to put it in a different way: The problem is not that too few patches get
merged.  The problem is that too few patches get reviewed.

Have a nice day,
Tomas Volf

I'd say that both things stem from the same premise, a disproportion of
available resources to the work that exists. This is not something
specific to Guix as a project, but can be observed in many other
projects as well (I couldn't name one larger free software or open
source project without this issue, but could easily name some where this
applies). The interests of a contributer sending a patch sometimes may
not align with the interests of the project/sometimes may not align with
the interests of commiters and so on. This happens and is a pretty
common reason for contributions being ignored and I see that as somewhat
a default modus operandi in many projects. Especially if available time
is a rather sparse resource.

I'd like to suggest to explicity refer to pragmatic ways forward in
Guixes Contributing manual section that don't rely on the availability
of other peoples (in this case committers/reviewers) time while
empowering contributors to use their changes in a good way if a patch
doesn't make it in/a bug report gets no reaction? Guix offers ways to
use packages outside of Guix proper in a pretty feasible and
maintainable way (manifests, setting up channels), maybe promoting them
as an alternative to having things in guix proper "as soon as possible"
(as that's not the only option to have things in a usable form) would be
beneficial.

I would just like to point out that while this applies to packages, it is bit
more complicated for services and other core parts of the Guix.  Combined with
the fact that Guix severely restricts what workflow model can forks use (e.g.
merge not being possible if the fork should be authenticated), maintaining
non-package modifications for longer periods of time can be a hassle.

So it could be beneficial to put some though into that as well.

Hi!  Why is it more complicated with services?  You don't need forks at
all to use packages and services outside of Guix proper.

For packages we have transformations, or I can just inherit.  But I am not aware
of such option for services (is there anything?).

Example: For long time the connman-configuration did not support a way to
provide a configuration file (well, it still does not but that is not the
point).  But I needed it.  So, what options I had?

1. Copy&paste the definition (-configuration, -service-type, ...?) into my
   system configuration and modify it.
2. Modify it in-place in my fork.

I tried 1. first, but keeping it up-to-date proved annoying, having zero support
from git.  Since I already made my fork (due to #65002, which just is not
possible to do outside Guix repository), I later switched to 2. and it worked
well, so I prefer that approach now.

I agree there is no issue for new packages nor new services, I should have
clarified that in my original message.

Have a nice day,
Tomas Volf

Today there are 1264 bugs with patches attached to them today [0].

We don't have any stats (that I'm aware of) that show how many patches 
the project reviews and either asks for edits, rejects or applies.

The group - and I hope the minutes reflect this - wanted to maintain the 
current standards. So the discussion of the pipeline focused on how we 
review more patches, and make decisions about them: whether that 
decision is to accept the contribution, ask for more work, or reject it 
as out of scope.

To answer your comment about the 'unconscious' assumptions - my personal 
view is:

* I don't think ALL patches should simply be accepted
* I do think that more patches need to be reviewed and a decision made
* I believe (no evidence) the project is missing out on great 
contributions amongst those 1200+ patches in the tracker
* I believe (no evidence) that potential contributors are put-off by the 
speed of review / lack of clarity

Thanks,

Steve

I don't think reviewers have to be committers.  If a patch is marked as
‘reviewed’ by a non-commiter, another person can just apply the patch
and push.  Although the commiter will take some responsibility in doing
so, and make sure the review was done correctly, it still makes their
work way easier.

My point is that not being committer shouldn't discourage people to
review patches.

How much more evidence does the project need to see in order to realize

I'll spare the list a lengthy analysis of the social dynamics but the
delegation of competency to the bottom is an unsuccessful practice in
many places.

Maintainers must close bugs in service to the public. There is no other

The best review I've had in years was done by a person who is not a
committer.  I see no evidence here.  And I'm unsure which plan you are
talking about (the plan?).

Two people can look at the same thing and reach different conclusions. I
see no evidence that large numbers of non-committers are eager to review
patches.

> What do you mean with "bottom"?

I'm sorry to put words into your mouth. I meant to quote an executive at
a bank who explained that strategy to me. The word "bottom" was his and
should have been a quote.

The executive referred to people without the authority to act on behalf
of the group.

I believe Guix would be better off to delegate responsibility (rather
than competency) by handing out commit access more generously but
imposing limits as to the type of changes a person may make.

The honor system will work fine.

> Reviewing != Closing

Maybe they should be the same. Two people looking at a patch (submitter
and committer) are more efficient than three people, i.e. a submitter, a
reviewer, and a committer.

It's one of several bottlenecks at Guix. Another is that committers
should commit what they think is right rather than ask for revised
patches.

Please give authorship to the submitter.

Kind regards
Felix

I believe very few people (commiter or not) are eager to review patches.

Committers are trusted, and obviously it takes time to be trusted, so
not everyone can be at once.  Reviewing requires less trust because the
committer can do a quick check that everything is in order before
submitting the patch.

It's less efficient if you compare flows for two patches, but for 1000
patches, it makes it easier to find reviewers, so in the end it's more
efficient.

I sometimes update the commit a little bit before pushing, and then
explain what I changed in my email.  But if the changes are big, I often
believe it makes more sense to ask for a v2.

I think it's the case?

Agreed - I put it a bit lower in the notes - clearly managed to bury it :-)

The discussion focused on increasing the number of Reviewers. A reviewer 
can be anyone - they don't need to be a committer.

The purpose of the proposed 'Patch Review' sessions is for contributors 
to come along and review patches together.

Steve

In the case of *reviewing patches* can you give some examples of:

1. Some patches from others you reviewed?
2. The steps you went through to undertake that review?

If for example, you started to review a simple update to a package how do you 
aproach it?

It would be great to hear directly from someone doing 'reviewing' on the 
specifics. Apologies, if this is going over old ground.

Re: Guix Days: Patch flow discussion

I, for one, would be willing to review patches, hoping that in turn my
patches would be reviewed instead of staying in limbo forever, which is
a drag on me submitting more patches.

Is there a procedure to follow, or do I just start replying "LGTM" to
patch email threads ?

Starting to review patches would be brilliant.

I agreed to organise some 'patch review' online sessions in the next couple of 
weeks. 

Organising a basic process is a good topic for that online session. For 
example, elsewhere in the thread someone mentions some tags we could use 
consistently so maintainers can find patches that have been reviewed easily. It 
would be great to agree those - try them for a bit - and document them in a 
'howto' so that everyone uses the same process.

Have these been announced somewhere yet (eg, with url & exact time)? If 
not will being subscribed to the help-guix list and/or checking the Guix 
blog be sufficient to receive notification? As someone who has sent 
patches in the past and intends to continue sending more in the future,

no need to be nervous! I would suggest to just start somewhere and learn
by doing. For patches, anyway the committer takes the final responsibility;
so if you can just add, for instance, "I use this package and it works for
me" this will be a useful point.

And do not be afraid to make mistakes; I have been taking part in Guix for
a long time now, and of course make mistakes from time to time. That
happens, and they can be corrected if they occur. What I find important
is to be upfront about them, and to ask for help if needed.

Hi Steve,

  ( On a side note, the triage of old bugs is a similar problem.  They
    are easy to find [2], read, check and send an email to
    12345@debbugs.gnu.org does not appear to me an issue with any tool.
    
    For what it is worth and without any willing of being harsh, I am
    able to count the people doing this boring task.

    What is hard to solve is the incentives for doing the boring, but
    necessary, collective tasks.

    Bah the usual problem of lengthy discussions with roommates in any
    shared apartment: who clean the bathroom? :-) )

Thanks for these notes and leading the session.  On my side, it was a
fruitful discussion.

Well, let me try to quickly summarize my conclusion of the session:

 1. We have a social/organisational problem.

 2. We have some tooling annoyances.



The easy first: #2 about tools.  The email workflow is often cited as
part of the issue.  That’s a false-problem, IMHO.

Projects that use PR/MR workflow have the same problem.  For instance,
Julia [1] has 896 open PR.  On my browser, it means 36 pages so if I go
to – 25 PRs per page – the still open submitted PRs:

   + the 6th page:  around Sept.2023 and Oct. 2023
   + the 12th page: around Apr. 2023 and Mar. 2023
   + the 18th page: around Jul. 2022 and Mar. 2022
   + the 24th page: around Jun. 2021 and May  2021
   + the 30th page: around Mar. 2020 and Oct. 2019
   + the 36th page: around Mar. 2017 and May. 2014

Obviously, an example is not a proof or an evidence.  It is just a
first clue. :-)

I will not speak about the channel ’nonguix’ but it gives another
clue.

That said, for sure, the tools need more love.  Thanks all the people
for all hard work over the years in this area – no name, you know, I
fear to forget someone. ;-)

So, yeah we need to smooth the technical burden for reviewing in order
to focus on the review itself.

To be clear, the email workflow might add burden on submitter side but I
am doubtful it is really part of the bottleneck for reviewing and
pushing submissions.


Although the tools might add some unnecessary friction, the net of the
issue is IMHO #1: reviewing is just boring and time-consuming.

Who feel accountable?  And for what?  That’s the question, IMHO.

If the number of submission is doubled, how do we increase the number of
people that feel enough accountable for doing the boring work?

  ( Maybe accountable is not the correct word.  Obligation neither.
    Well the kind of feeling that is okish if you skip the task but you
    know it will be better if you do it. )


Well, the difficult part is not pressing some buttons for merging and
pushing – whatever the tools or workflow.  The difficult part is to
scrutinize the submission.

I think the bottleneck is not the number of people able to push.
Instead, I think the bottleneck is the number of people confident with
the change for then pushing it.

The question is thus: how to build this confidence?


Look, when a committer has some free-time, most of the time, what is the
process: take first the “easy“ submissions for committing them – from
trivial updates to simple updates.  If free-time remains, then engage
with more “complex” submissions… ah no more free-time. :-)

Why starting by the “easy” submission?  Because it is less boring and
time-consuming; somehow it is easier to feel confident with that sort of
change for pushing it.

As a rule of thumb, about the time it takes – on average –, the order of
magnitude for reviewing is similar as the one for submitting.  Well,
from my experience and although I never did stats. :-)


All in all, I see two paths to move forward:

i) Non-committers can help.  On two fronts:

   + Answer to submitter with the changes for being compliant with Guix
     standards.
   
   + Follow-up on patches already commented but without an updated
     revision: upgrade the re-roll count by sending this revision.

     It eases for merging if I do not have to make many tiny edits
     myself.

ii) Create more teams or at least more people should commit to be part
    of a team and help in reviewing what they know.

    For instance, since Sept. (167 days ago) I have been CC in 108
    patches submissions.  Most of them are from ’core’ team that I would
    qualify as “complex”. :-)

    Many patches assigned to ’core’ team are sent by committers.  The
    issue is not being a committer or not.  Instead, being more eyes
    commenting would increase the confidence.  Thus it would reduce the
    workload.

    That’s the same for any team, IMHO.
    
    And I do not speak about patches that are not assigned to any team.


Somehow, we need to think how people would feel “accountable” for doing
the collective tasks with low, no direct or personal reward.

As with many non-technical topics, it is not easy.  Because it is a
collective journey not clearly identified – and not a kind of
reproducible bug to fix, even the tougher.

Last, the manual says:

    « As a rule of thumb, a contributor should have accumulated
      fifty (50) reviewed commits to be considered as a committer
      and have sustained their activity in the project for at least
      6 months. »

So if people are willing to take more responsibility to help the
project…


Well, while writing that I could have give a look to patches… ;-)

Cheers,
simon

Hello Simon,

first and foremost: I'd like to say a big thank you to all the people
working in the Guix community...

...and apologise if I still cannot do more to help.

yes, we (as a community) already had several discussions around the
false-problem named "email worfkow is too hard", I also dared to send a
*very* lenghty analysis comparing the _so_called_ "pull request model" [1] 

Unfortunately I'm pretty sure that _this_ false issue will be cited
again and again and again when discussing about "how to better help Guix
maintainers"

...unless the (info "(guix) Submitting Patches") one day will finally
(briefly) explain why the project is using an email based workflow and
not a "so called PR workflow" (to understand why PR workflow is "so
called" please read [1]) 

But all this discussion on the "email workflow" issue is more useless
when considering the commit authetication mechanism _embedded_ in Guix
since 2020;  I recently studied this blog post:

https://guix.gnu.org/en/blog/2020/securing-updates/

and it states:

--8<---------------cut here---------------start------------->8---

To implement that, we came up with the following mechanism and rule:

1 The repository contains a .guix-authorizations file that lists the
 OpenPGP key fingerprints of authorized committers.

2 A commit is considered authentic if and only if it is signed by one of
 the keys listed in the .  guix-authorizations file of each of its
 parents. This is the authorization invariant.

[...]

The authorization invariant satisfies our needs for Guix. It has one
downside: it prevents pull-request-style workflows. Indeed, merging the
branch of a contributor not listed in .  guix-authorizations would break
the authorization invariant. It’s a good tradeoff for Guix because our
workflow relies on [patches carved into stone tablets] (patch tracker),
but it’s not suitable for every project out there.

--8<---------------cut here---------------end--------------->8---

[patches carved into stone tablets] is a link to:

https://lwn.net/Articles/702177/
«Why kernel development still uses email»
By Jonathan Corbet, October 1, 2016 

an article with another ton of reasons why "all patch management tools
sucks, email just sucks less.

Anyway, since Guix is using the "authorization invariant" since 2020,
the "email workflow" is embedded in Guix :-D

Am I missing something?

I will not speak about kubernetes, cited in the above cited LWN article,

Email workflow makes the reviewing workflow _extremely_ easy, provided a
good MUA and a _little_ bit of self-discipline following the /easy/
guidance in (info "(guix) Reviewing the Work of Others")

This is the one and only reason.

I don't have anything to add, for now.


Happy hacking! Gio'

We do what we can when we can.  And you have done things to help.  Thank you for sharing your thoughts and perspective!  If there's nothing you can do at the moment, that's okay.  I have no doubt you'll step up again when you see an opportunity.  Who knows, someone may even delegate... ;)

Re: Guix Days: Patch flow discussion

[Daniel Littlewood]

Hi! I'm a complete newbie to Guix, which has the dual effects that I'm much
more excited about it than I otherwise might be, but the disadvantage that I
know nothing and am more likely to cause problems than not at the moment.
Nevertheless I thought I might be able to contribute something to the
discussion.

Something that is not obvious to me when people refer to reviewing patches, is
whether this is purely a matter of adding new packages to the main guix
channel, or of reviewing changes to the system in general, or both. As a
novice, I can imagine becoming comfortable as a package reviewer much more
quickly than as a reviewer of core patches to the system.

It's also not obvious to me whether you mean exactly "reviewing a backlog of
existing patches" or additionally "increasing the amount of patches submitted
and applied". I feel like both are probably good things but I can't tell what
you're focussing on exactly. If lots of gems were imported from other repos
like RubyGems and PyPi, which as I understand it is currently a
partly-automatic partly-manual process, would that be considered a win? What
about increasing version coverage among those packages that are covered?

One point brought up here is about tooling. I wonder whether there is any scope
for fully automatic review. In other words, for some classes of package we
might be able to say that if it builds in CI, and maybe the built package has a
command that's considered enough to say "it's working", then that's all the
review that's needed. I guess I'm mostly thinking here of cases where the
package is imported, partially or entirely automatically, from another repo (as
with `guix import`). So one could argue that as long as it looks like "the
rubygems import is working" then the guix package thus imported can be assumed
to be working too. I guess when I say this I am still mostly thinking of
importing entire histories of a package (lots of versions simultaneously)
without multiplying out the work involved to a huge degree.

One of the points brought up earlier is whether it would be better to have
interactive "review parties" or comprehensive documentation about what
constitutes a good review. Obviously these are not mutually exclusive. But for
my part, I think documentation gives you more "bang for your buck", for a few
reasons:

  1. Documentation is online all the time, whereas interactive sessions are
subject to people's work schedules, time zones, personal commitments, etc.

  2. Documentation is more likely to be complete, and to become more likely to
be complete over time, whereas in meetings (or when doing your first solo
review following the meeting) it is easy to forget some steps or criteria to
check.

  3. Reading docs can be done by anyone, with no commitment to follow up. I
think some people are just scared off socially by the idea of having to join a
meeting in order to learn how to do reviews well. Obviously this is a personal
thing and varies - some people find a welcoming atmosphere in a virtual meeting
much better than a faceless documentation screen. For my part I think I would
prefer to read until I know the basics, and then might prefer to do it
alongside other people. A "patch party" would not convert me from
non-contributor to contributor, but it might convert me from a
seldom-contributor to an active one. Again, there is obviously variation here
among people.

In case it is not obvious, I have only recently joined guix-devel, but would be
keen to help out if I can. If there are things I can read to get "up to speed"
that would be really helpful!

All the best,
Dan

Hello Dan,

thanks for your thoughts! I think I will restrict my replies to guix-devel
to keep them in one place; the following are just my personal opinions.

Both! And indeed what you write is correct, reviewing packages is easier
than services, which is probably easier than other changes. (Personally,
I feel confident only with packages.) Of course then people should only
review things they are comfortable with.

The discussion was about the backlog; in particular also about negative
feelings by contributors of patches that take a long time to be applied.
Of course adding more packages is also a welcome activitiy (but only
makes sense if enough of them are applied in the end...). We concentrated
on "reviewing" to ease the burden of "committers", since reviewing is open
to anybody.

I do not think so. Quality is an important aspect of Guix; for instance,
we ask for non-marketing descriptions, which would be difficult to test
automatically. We already have "guix lint", which does some of the work.
And there are fully automated channels such as for CRAN, but which then
are potentially of a lesser quality.

Notice that "easy" packages are also easy to review; most of the time,
there is not much to do about the result of "guix import pypi ...".
Things become more tricky when phases need to be added, to understand
what is going on, and then I usually also look at comments (or criticise
their absence).

Agreed, there should not be any "having to join a meeting". The idea of
organising one comes from the goal of making the activity more social and
less boring. Apart from that, you can start today and need not wait for
a bug squashing party :)
