Subject: emacs.pdmp file name (--fingerprint)

Severity: wishlist

Hi!

Recently, in git head, the default name for the emacs.pdmp file
changed to emacs-someverylonghexstring.pdmp (I think in commit
e81f1faca4382ed5c8f15fec84fb7c900a5468f9).

I don't know why this is preferred to the simple emacs.pdmp that was
there before. I do not see a rationale in the commit messsage.

I'm sending this mail because this filename causes problems for
packagers who prefer maintaining static file lists to make sure
exactly a known list of files is installed by a program.

Can you explain why this was changed?

Can it perhaps be changed back? Or is there an option to not use it?

Thanks,
 Thomas

The commit message refers to bug#42790, which has the discussion.

If you rename the file to "emacs.pdmp", Emacs will still find it, but I
guess this isn't documented.  We could also add a configure option to do
this renaming automatically, I guess?

Anybody got an opinion here?

Yes, we donʼt have enough configure options, and our Makefiles are too
simple /s

    Lars> Anybody got an opinion here?

We should document the 'emacs.pdmp' thing, but after that isnʼt it a
packaging issue? Whomever wants 'emacs.pdmp' just copies the actual
pdmp file to that.

Sure.  Where's a good place to document this so that Debian maintainers
(etc) will find it?

etc/NEWS? This is an emacs-29 thing, no? Thatʼs where we announced the

Yes, but it should be documented forever -- people will be wondering
later, too.

But I see that I forgot to mention it in NEWS, and it's definitely
NEWS-worthy.

Me, I wonder how will those distros code with the *.eln files, which
also include hashes that aren't known in advance.  Solving the issue
with the pdumper file will still leave this other one, with many more
files.

So perhaps the distros will just have to adapt?

What are .eln files? I don't see any in the NetBSD build.

Here are the files for the emacs-git package.

https://github.com/NetBSD/pkgsrc-wip/tree/master/emacs-git

The PLIST contains the files that get installed, the Makefile and
options.mk contain any enable/disable arguments to configure.

> So perhaps the distros will just have to adapt?

I've changed the package to rename the emacs-*.pdmp file to emacs.pdmp.

Theyʼre the output of the native lisp compiler, which will only get
generated if you successfully configure
'--with-native-compilation'. See etc/NEWS for details.

You didn't configure --with-native-compilation, I guess?

That's a good point.  So perhaps we shouldn't document how to get to a
known-name setup, because that won't work for nativecomp?

Packagers like RPM can cope with that by using wildcards.  They can also
generate file lists on the fly.

That's what I think.  The actual problem is much larger than just one
file.

I feel like +1'ing this.
Plus they also warn if there are installed but unpackaged files, so
there isn't really a pressing need to announce/document the name change.
I see no need to add an option to revert to "emacs.pdmp".

>>> I've changed the package to rename the emacs-*.pdmp file to emacs.pdmp.

A mistake IMO.

That seems to be the conclusion here, so I'm closing this bug report.
