There's a 404 when attempting to fetch from the repository:

No, there isn't. There's a 404 when trying to fetch precompiled archives. This is not a bug. (See #68869.) Since precompiled archives were not available, MacPorts tried to fetch the source, in this case from a git repository. It failed with this error (which is not a 404):

fatal: the remote end hung up unexpectedly

I had noticed this too on my macOS 12 machine but hoped that it was just a transient problem, but I guess it isn't. I had worked around it temporarily by removing --shallow-since=2024-03-25T00:00:00 from the Portfile. I guess maybe we have to remove that part permanently if bitbucket's git servers no longer accept this option. That results in fetching the entire history of the repository, however, which is large and takes a lot of time and disk space. Maybe there is a different flag we can use that would similarly limit the fetch to only what we need. Or maybe there is a way that we can fetch a distfile instead of fetching from the repo.

[George9000]

Ok. Thanks. Following your suggestion, I used vim to remove that chunk from the Portfile.

sudo vim var/macports/sources/rsync.macports.org/macports/release/tarballs/ports/aqua/emacs-mac-app/Portfile

on line 98 of the Portfile, remove

--shallow-since=${date}T00:00:00

The port then built without issue.

I'm not seeing this. On my machine:

% sudo port -d fetch emacs-mac-app-devel

I'm not sure why this fails. It could be a problem specific to bitbucket and/or the path our network traffic takes to their server.

But maybe we don't need to investigate why --shallow-since doesn't work and instead focus on avoiding the need to use it. No other port uses this flag.

You're presumably using it to limit network traffic and disk space so that you don't fetch the entire repository when you need just one commit.

Why not fetch just that one commit then? ​git has this capability now. It didn't used to, back when MacPorts git fetching commands were implemented.

It should be fixed in MacPorts base, then. A problem is that the git (and hg) fetching code does things manually instead of using the typical command_exec method that's used elsewhere in MacPorts base.

A patch to fix git (and hg) fetching to use command_exec was submitted in #29093. If we get that fixed, then switching the git fetching procedure to fetch just the required commit when one is specified should be fairly easy. That method does work to fetch the emacs-mac-app-devel repository on my system, when done manually on the command line.

However, ideally, the port should not fetch from git at all; it should fetch from a distfile. Taking a quick look at the bitbucket portgroup it seems like it should support that just as github and gitlab do but I see at least one problem with the bitbucket portgroup and will look at it more later.
