bug#69528: 30.0.50; [BUG] transient.el is not a member of package--builtin-versions

[No Wayman]

Transient.el was added in 28.1 according to NEWS.
It is not a member of package--builtin-versions for any of the 
following Emacs versions: 28.1, 28.2, 29.1, 29.2.

I believe the behavior described here is due to this:
https://www.reddit.com/r/emacs/comments/1b69v1b/let_magit_330_use_builtin_transient/

To summarize, the user has a built-in version of transient.el 
shipped with Emacs 29.2.
They installed magit 3.3.0, which requires transient 0.3.6. 
Instead of package.el seeing magit's transient.el dependency as 
satisfied by the built-in version, it installed the latest 
version.

I've patched Elpaca, which relies on package--builtin-vesrions, 
due to similar complaints about transient.el being pulled in 
despite the built-in version satisfying a dependency.

At least on Emacs 30, (assq 'transient package--builtin-versions) gives
me a non-nil value.  I can confirm that this is the case on the emacs-29
branch.

I suspect this commit resolved the issue, since
`loaddefs-generate--parse-file' only checks the version header, not the
package-version header.

I suspect that whatever you did, won't help us since this specific issue
will be resolved by the time any package.el-related fix would be published?

What about making `lm-version' handle the "package-version" header then
using `lm-version' in loaddefs-generate--parse-file?  See patches.

My main concern was if we want to have Package-Version always override
Version, but if my patch modified loaddefs-gen, then I don't think there
is much of a difference if we change lisp-mnt instead (in terms of the
generality of the change).

So I am fine with the change, and think we can merge it.  Eli: Is master
still fine for these kinds of changes?

If it would be more appropriate, I can resubmit another patch with
"Version" used preferentially over "Package-Version".

No, I believe that would be wrong, at least going by these quotes from
the manual:

(elisp) Simple Packages:

     The version number comes from the ‘Package-Version’ header, if it
  exists, or from the ‘Version’ header otherwise.  One or the other _must_
  be present.  Here, the version number is 1.3.

(elisp) Library Headers:

  ‘Package-Version’
       If ‘Version’ is not suitable for use by the package manager, then a
       package can define ‘Package-Version’; it will be used instead.
       This is handy if ‘Version’ is an RCS id or something else that
       cannot be parsed by ‘version-to-list’.

So the patch is fine as it is.

I think so, yes.  But maybe I don't fully understand the effect of
this change?  Can you describe it?

I also added the other maintainers, in case they have opinions on
this.

Thanks.

I think the first patch is right, i.e. to use

    (lm-version)

instead of

    (lm-header "version")

So let's install that one, I think.

The effect of the second patch is to change `lm-version` to look for a
"Package-Version" header if there is no "Version" header.

This has two problems:

1. We didn't do that until now, and it's not clear to me what is the
   issue that is prompting this change.  The transient.el issue seems to
   have been fixed already.

2. The way I read the manual, it seems like "Package-Version" should be
   preferred over "Version", if it exists:

        ‘Package-Version’
             If ‘Version’ is not suitable for use by the package manager, then a
             package can define ‘Package-Version’; it will be used instead.
             This is handy if ‘Version’ is an RCS id or something else that
             cannot be parsed by ‘version-to-list’.

   I'm also not sure we need to support packages with unusual versions
   like RCS id's these days.  Is that use case still relevant?  Perhaps
   we should simply deprecate the "Package-Version" header?

Sorry for the late response, but Stefan summaries the situation well
below.

FWIW I use this for some of my own scripts that I version using RCS, so
I'd appreciate it if that functionality would stay.

OK, so let's keep it.  But shouldn't the below be the correct order

Of course, that was also the change proposed in my first patch but I
didn't notice the change in Joseph's suggestion.

Bonus points if you add a test for this one.

See CONTRIBUTE for details, but this should read:

* lisp/emacs-lisp/lisp-mnt.el (lm-version): Prefer version in the
"Package-Version:" header.  (Bug#69528)

It would be good to fix the docstring here to clarify that it can come
from the "Version" or "Package-Version" headers too.

This should read something like this instead:

* lisp/emacs-lisp/loaddefs-gen.el (loaddefs-generate--parse-file):
Prefer 'lm-version'.  (Bug#69528)

BTW, I think this is a backward-incompatible change.

Whether we want `lm-version` to return the info from `Version:` or from
`Package-Version:` depends on what we want to do with it.

When do we want lm-version to return Version and not Package-Version,
where a (lm-header "version") wouldn't serve as a more specific
replacement?

FWIW the function is used in a single place (in the core, lm-report-bug)
and both on ELPA and NonGNU ELPA, all instances appear to might as well
be using `package-get-version' (if it were not for the version of Emacs
they are depending on).

I don't know, but if we never want to return the value of `Version:`
when there's a `Package-Version:` then we don't need `Package-Version:`
either (we should just replace the `Version:` field with the content of
`Package-Version:`).

IOW the very existence of `Package-Version:` is predicated on the desire
to distinguish the two.

AFAICT, we currently use it in `lm-report-bug' and with Joseph's patch
we will use it also for `loaddefs-generate--parse-file'.

I don't have a strong opinion, but there seems to be a mismatch between
what the code does and what the documentation says.

    "The version number comes from the ‘Package-Version’ header, if it
    exists, or from the ‘Version’ header otherwise."

    (info "(elisp) Simple Packages")

`lm-report-bug` does not seem directly related to ELPA packaging, so it
makes sense to use just `Version:` there, which is presumably the format
that the maintainer favors (where the `Package-Version:` header is
instead the format that the maintainer was forced to add to accommodate
the restrictions of the ELPA protocol).

In contrast, `loaddefs-generate--parse-file' is about generating info
for `package.el`, so this one *does* want to use `Package-Version:`
if it's present.

Of course `lm-report-bug` would work likely fine as well if it uses
`Package-Version:`.  The distinction is probably not that important in
that case.

Definitely.  My only point was that the patch changed `lm-version` in
a backward incompatible way (tho arguably a minor one) without even
mentioning it.
Maybe it's OK to do that, but let's do it consciously.
If not, then we'll presumably add a new `lm-package-version` (which
wouldn't look at RCS keywords either).
