That problem with symlinks that Norbert and I have been talking about will go away if we make Tramp use 'ls -alL' to get the directory listings. But I'm not sure if that is the right thing to do. Listing a directory like that would mean that you would not be able to tell which files/directories were symlinks. They'd all appear as normal files/directories.

I think that tramp-handle-file-truename should be fixed first. I've worked on it some more. I've also made it do more debugging output. Please try (file-truename "/[user@...]/path/to/file") for various names. Maybe some filenames relative to the home dir, some containing absolute symlinks, some containing relative symlinks. What do you see? If file-truename works but actually opening the file doesn't, then I'll have to look at it again. kai -- Simplification good! Oversimplification bad! (Larry Wall) |

Test environment:
- "local" is an ssh alias for localhost, logging in as user
"root"
- 'rel-symlink' is a relative symlink in '/root/' that points
to './temp/'
- 'abs-symlink' is an absolute symlink in '/root/' that points
to '/root/temp/' (the same as 'rel-symlink')
(file-truename "/[local]rel-symlink")
"/[sm/local]//root/rel-symlink"
(file-truename "/[local]abs-symlink")
"/[sm/local]//root/abs-symlink"
This is another test, not using tramp (so I could see what it should
look like :-) )
Test environment:
- 'rel-symlink' is a relative symlink in '/home/steve/temp/'
that points to './temp/'
- 'abs-symlink' is an absolute symlink in '/home/steve/temp/'
that points to '/home/steve/temp/temp/'
(file-truename "~/temp/rel-symlink")
"/home/steve/temp/temp"
(file-truename "~/temp/abs-symlink")
"/home/steve/temp/temp"

Doesn't look like either works. :-(

It is a complete mystery to me where the "//" comes from. This
doesn't happen on my system.
But if you set tramp-verbose to 10, you should get a lot of messages
what file-truename is doing. I wonder if maybe split-string fails
for you?
What does (split-string "/foo/bar" "/") return? On Emacs 21, it
returns ("foo" "bar").
I think I should install XEmacs pretty soon so that I can test this
stuff. Hm. Debian woody has 21.4.1 -- is that good enough for
testing? Or should I make a local build of something more recent?

On XEmacs 21.4.5 it returns ("" "foo" "bar").

Yeah, that's probably good enough to get started. 21.4.6 is the latest
gonna-be-released version. If you want to bleed, you can try 21.5.3, but I
think the odd-numbered minor releases are generally just for XEmacs
developers.

I think that would be fine, most of the problems with the earlier 21.4 releases were related to Windoze. 21.4.6 is the new kid on the block. --=20 |---<Steve Youngs>---------------<GnuPG KeyID: 10D5C9C5>---| | XEmacs - It's not just an editor. | | It's a way of life. | |------------------------------------<youngs@...>---| |

Aha. I now found an XEmacs and there, (split-string "/foo/bar" "/")
returns ("" "foo" "bar"). So I hacked a compat function and now use
that, instead.
What do you see with the new version of Tramp on XEmacs?
I hope that I have time to test the new version on XEmacs soon.
[time passes] Okay, I now logged in on schulz and did this:
cd /tmp
mkdir kaifoo
ln -s kaifoo kaifoo.link
ln -s /tmp/kaifoo kaifoo.abslink
And (file-truename "/[sm/schulz]/tmp/kaifoo.link") and (file-truename
"/[sm/schulz]/tmp/kaifoo.abslink") both return the right value.
XEmacs users, please test and report your findings. Thanks.

The logic in there is not so complicated, but I've managed to get it wrong now many times. What's happening with my brain? Anyway, I've hacked on it more. If the current CVS still doesn't work, please have a look at the aforementioned (?) function and try to figure out where it's gone wonkers. Thanks a lot. kai -- Simplification good!
