This *is* a non-backward compatible > change from the perspective of Eglot's maintainer. We were talking about users installing and updating packages. The CI scenario doesn't belong here. It is also much less important one (test suites are always required to chase the changes in development).

Classic https://xkcd.com/1172/.

Except that, based on what we have (see below) ,we don't really have an "upgrade" operation, we only have "install" and "delete" (i.e. "uninstall"). So maybe we should preserve that, to minimize problems and user surprise/confusion. > > In interactive invocation, package-upgrade calls completing-read with > > its 4th argument non-nil, so you cannot select a package which is not > > in the collection returned by package--updateable-packages.

Otherwise, I don't see why we would need two separate options: they do the same job and have the same meaning from the user's POV. > >> Because > >> package-upgrade does not have a menu entry, or a button anywhere, > >> whereas package-upgradable-builtins can be altered from the Customize UI. > > > > Maybe marking a package in the list for update could be interpreted as > > "upgrade that, no questions asked", and we will need no user options? > > There is no handy "upgrade that" binding in the packages menu.

This is what > currently an upgrade consists of. Yes. So users could manually mark an new version for installation, and if needed mark the old version for deletion, thus indicating that they want this upgrade. No separate option to indicate the same is needed. > All this is to say, the first step (upgrading Eglot to the version from > ELPA) will be less user-friendly compared to the other UIs we have.

I don't see why it would be less user-friendly. > My point here, however, is that commit 580d8278c5f48 improved the > situation to a lesser degree that some people here might have expected. One again: commit 580d8278c5f48 solved precisely the problem which opened this bug report, nothing more, nothing less. The rest are late additions, which were not on the table when the original bug was discussed. So the above complaint is at least unfair. > >>> If people agree with that, I don't think I'll object.

We agree. I'm saying that your suggestion to make package-upgrade a more important command is by itself a breaking change: there's no "upgrade" operation, per se, in the current code. > But we can conclude that we do have two different installation actions: > > - package-install which will install the latest version of a package, > but only if it's not installed; > - package-menu-mark-install, which will mark a specific version for > installation, disregarding whether some earlier version is already > installed; the previous version will remain installed still. Which is again a breaking behavior change, AFAIU. Is this a good idea so late in the development of Emacs 29? > >>>> Could you specify which problem it's currently solving?

I don't have a reasonable plan to > present for doing that in Emacs 29, so far. There's no "split". What I wanted to point out is that we don't seem to have a clear vision of these two commands, since they are confusing intertwined. In fact, one could argue that package-upgrade in its current form is simply a convenience shortcut for "delete old and install new".
