Sorry; didn't read the bug report closely enough -- I assumed just opening the tgz file would trigger it.

How have you tried to reproduce it?
I did:
emacs -Q .../test.tgz
M-x tar-untar-buffer RET
and it prompted me (in a new *Keys* buffer) to choose a key to encrypt
some file.

Here's how I hope for it to work:
write-region-literally checks file-name-handler, finds HANDLER and delegates
to it, if HANDLER has a special handler for it (e.g. jka), then that
handler will presumably end up calling write-region, but if it doesn't,
then it rebinds inhibit-file-name-operation=E2=80=99 and
=E2=80=98inhibit-file-name-handlers=E2=80=99 and calls write-region-literal=
ly again
which this time won't find this file-name-handler.

I'm suggesting to add write-region-literally and the "inverse" or
insert-file-contents-literally. Just like
it is the case for insert-file-contents(-literally), there are in theory
middle points, but in practice those can be reached by manually
performing the extra encoding/decoding that the `-literally` version
doesn't do but that we'd need in this case.
IOW since we don't have any
`insert-file-contents-literally-but-please-do-the-coding-system-decoding`,
I don't think we want a `write-region-literally-but-not-quite`.

In the absence of a file-name-handler, it should just defer to write-region.

I am. I'd even say it should signal an error if the buffer isn't unibyte.
Anything else would be asking for trouble.

Well, we'll need to make this more accurate, to exclude encoding, EOL conversion, and the likes, but okay. (And "raw" sounds like a wrong word for this.) > ;; FIXME: Yuck!!

Probably. But the question of what should that do (since you rejected tweaking inhibit-file-name-operation for that) still stands, I think. And I'm not sure we will always want to disable encoding and EOL conversion, so that should be an add-on for "truly" literal I/O.

Well, the handler will execute code rather than write it, but yes,
someone will have to change jka and epa to implement this new behavior
of write-region.

Hmm... I think you're referring to the question of what this new
"write-region-provides-raw-file-contents" should precisely mean, so that
maintainers of file-name-handlers can decide how to implement it.
Here's one attempt: "the data provided to write-region reflects the actual
bytes that should be placed into the file rather than the data returned
by `insert-file-contents`".
Maybe another way to define it would be: "the data provided to
write-region reflects the data one would like to get from
`insert-file-contents-literally` rather than that returned by
`insert-file-contents`"
And that made me discover that we have another occurrence of the same
problem in `insert-file-contents-literally`:
(defun insert-file-contents-literally (filename &optional visit beg end replace)
"Like `insert-file-contents', but only reads in the file literally.
See `insert-file-contents' for an explanation of the parameters.
A buffer may be modified in several ways after reading into the buffer,
due to Emacs features such as format decoding, character code
conversion, `find-file-hook', automatic uncompression, etc.
This function ensures that none of these modifications will take place."
(let ((format-alist nil)
(after-insert-file-functions nil)
(coding-system-for-read 'no-conversion)
(coding-system-for-write 'no-conversion)
(inhibit-file-name-handlers
;; FIXME: Yuck!! We should turn insert-file-contents-literally
;; into a file operation instead!
(append '(jka-compr-handler image-file-handler epa-file-handler)
(and (eq inhibit-file-name-operation 'insert-file-contents)
inhibit-file-name-handlers)))
(inhibit-file-name-operation 'insert-file-contents))
(insert-file-contents filename visit beg end replace)))
So this FIXME suggests maybe we should introduce a new file operation
`write-region-literally`?

All files use dynamically scoped variables. `lexical-binding` only
determines the scoping to use for those vars that aren't declared as
dynamically scoped. The fact that tar-mode.el hasn't (yet) been
converted to use lexical-binding has no effect on the above example
(because I presume there that write-region-provides-raw-file-contents
would be a variable declared somewhere in files.el as being dynamically
scoped, like file-name-handler-alist).

I know. Maybe we can extend it to allow the source to be a buffer?

Not sure why you think that could make it not useful.

No, no: we do want the file-name-handler to be called.
We just want it to receive enough info to determine how it will do its
job (e.g. whether it needs to compress/encrypt the data or not).

It isn't clear to me how you distinguish between the file-name handlers that should and shouldn't be disabled here. I assume you are aware that Tramp doesn't necessarily send the file's contents verbatim over the wire? One way of teaching find-file-name-handler to distinguish between various handlers is to have some properties on the handlers' symbols. Then we could bind some variable to the list of properties to filter out "unwanted" handlers. But we should come up with a useful list of properties first, and for that we need a clear distinction I ask about above.

It looks like `copy-file` only deals with files and not buffers, so we would need to find a way to use it from tar-mode. Looking at the source in fileio.c, it also seems like it uses `find-file-name-handler` for `FILE` or `NEWNAME`, so it's possible it won't be useful for us. If we added a new argument to `write-region` like you mentioned, say `RAW`, could we then use symbol properties to decide whether the found file name handler can be used or not? Like so: (put 'jka-compr-handler 'provides-raw-file-contents nil) (put 'epa-file-handler 'provides-raw-file-contents nil) (put 'tramp-file-name-handler 'provides-raw-file-contents t) (put 'tramp-completion-file-name-handler 'provides-raw-file-contents t) (put 'file-name-non-special 'provides-raw-file-contents t) The downside being that anyone adding a new file name handler must remember to set the property to t if needed.

Exactly, it's no better.

> explicitly mentioning them.
Instead, you should state the property you want, and then let each
file-name-handler decide how to handle that property. E.g.:
(let ((write-region-provides-raw-file-contents t))
(write-region ...))
Of course, the problem here is that by using dynamic scoping, this var
will affect all write-regions that will take place during this call,
which might lead to more problems.
Maybe it would be better to have it as an argument to `write-region`, or
to introduce a new function?
Or maybe, not use `write-region` but `copy-file` instead (which already
provides the expected semantics (i.e. it doesn't (un)compress or
(en/de)crypt, IIUC).

Ok, I see. How about:
(defmacro with-literal-file-name-handlers (&rest body)
`(let* ((allowed-file-name-handlers '(tramp-completion-file-name-handler
tramp-file-name-handler
file-name-non-special))
(file-name-handler-alist
(seq-filter (lambda (c) (memq (cdr c) allowed-file-name-handlers))
file-name-handler-alist)))
,@body))
I realize that in this case I'm hard-coding the specific
file name handlers that *can* be used. I'm not sure how to express "only
use these file handlers" without explicitly mentioning them. I'm also
not sure if we only care for `tramp-file-name-handler`, or for the three
I listed above.

Could this be achieved by doing:
(let ((inhibit-file-name-handlers '(jka-compr-handler epa-file-handler))
(inhibit-file-name-operation 'write-region))
...)
or is there a reason why a specific mechanism for this is needed?

Yes, of course, but the question is what it does when the tar's content
has a name that ends in `.gz` or something like that. I now see that it
has a hack in write-region which looks at the contents to detect if it's
already compressed.
[ I guess this can lead to problem in odd cases such as when you
manipulate a file of type "foo.mypkg" where mypkg is defined as
a format that is always gz-compressed: if you save it as
"foo.mypkg.gz" jka-compr won't re-compress it, but then when you open
it, it will uncompress it before trying to handle it as a ".mypkg" at
which point the mypkg tool might signal an error because it expected
the ".mypkg" to be compressed. If this will ever happen is
anyone's guess, but it look sufficiently contrived that I'm not
too worried. ]

I think there should be a way to tell `write-region` that the content
should be written as-is into the file (and hence override jka-compr and
epa but not tramp). I don't think there is such a thing yet, tho, so
we'll have to invent it.

Package: Emacs
Version: 27.0.50
When untarring a file whose contents include a GPG keyring named with
a `.gpg` extension, `tar-untar-buffer` ends up trying to encrypt the
keyring because the `write-region` call for this file gets handed to
`epa-file-write-region`.
