I have a tarfile (a.tar) containing a compressed text file and a jpeg
file.
So, a.tar contains b.gz and c.jpeg
Emacs opens up the jpeg correctly - that is - I see the picture
The compressed file is opened as a binary file - emacs does not
uncompress it.
Is there a way of persuading emacs to open the gzipped file correctly?

Try to customise auto-compression-mode – setting it to jka-compr
should give you what you want. Maybe jka-compr-compression-info-list
needs some customisation too.

Should this be needed? Is this a bug, or?

Well, my first question should have been how it works uncustomised,
i.e., with emacs -Q... (Older versions of GNU Emacs did need some
customisation, which now, in GNU Emacs 23, might produce errors.)

But if I open a gz file from outside a tar file, it uncompresses the
file.
I also tried running with emacs -Q, and it also failed to uncompress the
gz file contained in the tar file.
You suggested that I customise auto-compression-mode, but that variable
deals with gz files. In any case, could you give me the syntax for
setting auto-compression-mode to jka-compr?
I suspect this is a tar-mode.el bug. Should I report it on the bugs
list?

I have this customisation for GNU Emacs 22:
'(jka-compr-compression-info-list (quote (["\\.Z\\(~\\|\\.~[0-9]+~\
\)?\\'" "compressing" "compress" ("-c") "uncompressing" "gzip" ("-c" "-
q" "-d") nil t "\x1f\x9d"] ["\\.bz2\\(~\\|\\.~[0-9]+~\\)?\\'" "bzip2ing"
"bzip2" nil "bunzip2ing" "bzip2" ("-d") nil t "BZh"] ["\\.tbz\\(\\|2\\)
\\'" "bzip2ing" "bzip2" nil "bunzip2ing" "bzip2" ("-d") nil nil "BZh"]
["\\.\\(?:tgz\\|svgz\\)\\'" "compressing" "gzip" ("-c" "-q")
"uncompressing" "gzip" ("-c" "-q" "-d") t nil "\x1f\x8b"] ["\\.g?z\\(~\\|\
\.~[0-9]+~\\)?\\'" "compressing" "gzip" ("-c" "-q") "uncompressing"
"gzip" ("-c" "-q" "-d") t t "\x1f\x8b"] ["\\.dz\\'" nil nil nil
"uncompressing" "gzip" ("-c" "-q" "-d") nil t "\x1f\x8b"])))
/Users/pete/.emacs-Abrichtung-AquaMacs.el: '(auto-compression-mode t
nil (jka-compr))
and I had this for its variant Aquamacs Emacs (Mac OS X only):
'(auto-compression-mode t nil (jka-compr))

Yes, please do! I tried it this morning by creating an archive
comprised of other archives and I then tested a newly compiled version
of GNU Emacs 23.1.90 from CVS. When I visited the included TAR type
archives they were opened in fundamental mode (instead of tar-mode)
and unreadable. It worked well with ZIP files: their contents was
shown. But when I tried to view/visit an archive member it failed:
unzip: cannot find or open /Volumes/Halde/_neu/Beispiel.tar.bz2!./
random.zip, /Volumes/Halde/_neu/Beispiel.tar.bz2!./random.zip.zip or /
Volumes/Halde/_neu/Beispiel.tar.bz2!./random.zip.ZIP.
(/Volumes/Halde/_neu/Beispiel.tar.bz2 is my archive of archives,
random.zip is the member mentioned.)
When I tried to switch to tar-mode I received:
byte-code: ^_\300\213^H^H\301\246\322\201H has size -362276419 -
corrupted
This echos the first ten bytes of the archive file. Before *Messages*
buffer recorded:
File mode specification error: (error "^_\213\^H^H\346ҁH has size
-362276419 - corrupted")
Similiar reports were output when I tried to visit other TAR files in
this archive.
Compressed "text-like" files in the archive were not decompressed.
With a GZipped file I received:
Error during redisplay: (wrong-type-argument number-or-marker-p nil)
File mode specification error: (wrong-type-argument wholenump nil)
With ncurses-5.4-20040711-patch.sh.bz2 I received:
Setting up indent for shell type sh
setting up indent stuff
Indentation variables are now local.
Indentation setup for shell type sh
but I saw only the compressed "text," easily recognisable by the
file's header "BZh"...
With GNU Emacs 22.3 I get a "File mode specification error"...
The common failure is that tar-mode is not activated in the TAR file
inside the TAR file and that to unzip is passed a wrong file name, one
that is concatenated of the archive file's path name, a "!" and the
ZIP file's relative path name – although it does exist in the file
system! (Adding .zip or .ZIP is an automatism of unzip when it fails
to find "file name.")
