bug#7583: 23.2; ido loads tramp too eagerly

bug#7583: 23.2; ido loads tramp too eagerly

[Dave Abrahams]

This seems a bit overeager.  It takes a while to load up tramp, and ido
shouldn't need to consider tramp filename completions if tramp isn't
already loaded.

emacs -Q
`M-x ido-mode RET'
`C-x C-f'           <wait while tramp loads>

bug#7583: 23.2; ido loads tramp too eagerly

I (still) cannot speak about ido. But Tramp 2.2 has been rewritten for
Emacs 24 to load only the minimum part at startup. More Lisp objects of
Tramp have been moved to autoload files.

Running this recipe with Emacs 24.0.90, I don't see a serious delay due
to Tramp. Do you still believe we need to fix something?

Best regards, Michael.

Would help to set ido-enable-tramp-completions to nil, and set it back
to t after loading tramp?

The problem, I guess is tramp start immediately when you enter the first
":" due to `tramp-file-name-regexp'.  This is a common problem for all
incremental UI with tramp.
In anything i let bound `tramp-file-name-regexp' to another value that
wait you type in the second ":".
I don't know for ido but due to it's nature, i guess it's the same.

See `anything-ff-set-pattern' in anything-config.el.
http://repo.or.cz/w/anything-config.git

  (let ((methods (mapcar 'car tramp-methods))
        (reg "\\`/\\([^[/:]+\\|[^/]+]\\):.*:")
        cur-method tramp-name)

Where reg replace the tramp regexp.

You disable then method / user name / host name completion. If you want
so, you shall make it configurable, at least.

Actually yes, this completion is disabled, but why do you have to start 
tramp to have such completion?
i.e There is no need to start tramp to make a completion based on the
content of ~/.ssh/config

Maybe tramp should have other regexp(s) that (try to) complete this without
starting tramp.

Note that this kind of completion lead to bugs in other places in Emacs.
e.g create an ssh hostname in ~/.ssh/config that start by "t", and in
eshell, write /t and <tab> to complete to "/tmp"; tramp will start and 
fail.

Not needed i think.

example1:

1a)prompt: /t! => complete on all hostname/method/directories starting by t
                  without starting tramp

now i choose thievol in list completion, i have now:
1b)prompt: /thievol:! => enter the ":" if thievol is member of hostname completion
                         list and not a directory and start tramp.

example2:

prompt: /s! => same as in 1a 

now i choose scpc in list completion, i have now:
prompt: /scpc: => same as in 1b and now i complete on only hostname list

now i choose thievol in list, i have now:
prompt: /scpc:thievol => i do not start tramp, waiting user enter the
                         last ":", when it's done start tramp only now.

Tramp gives you (as package ffap, for example) a mean to configure its
behaviour. You could let-bind `non-essential' to t; in this case Tramp
wouldn't disturb your own completion algorithm.

ido.el and icomplete.el use this variable such a way.

If you want to disable Tramp completely, you could let-bind `tramp-mode'
to t.

Best regards, Michael.

I do not know what that means.  AFAIK there are two relevant "actions":
- start a Tramp session.  This means to connect to a particular host, so
  clearly it can't be done before you've actually typed the complete
  host name.
- load "tramp.el".  Nowadays, this should be barely noticeable.
  But indeed I do see a "Loading tramp-sh...done".  I wonder where this
  message comes from, we should probably suppress it.

Hmm, yes. Some months (years?) ago, when the "Loading ..." message has
been removed from load.el, there were complaints that loading tramp.el
takes a long time tp load, and nobody knows what happens. So I have
added this message to tramp.el as exceptional case.

Now Tramp loads better, and I should remove this message, indeed.

Will do.

So you're saying that Tramp tries to connect to "toto" when you type
"/toto:"?  If so, I think the problem is indeed the same as for
icomplete and ido and the solution is to bind the variable
`non-essential'.

Yes, but that is what we expect. (/toto: should be a valid hostname
maybe set in ~/.ssh/config)
What we don't want is when you write:
/ssh: => tramp try to connect
or
/sudo: ==> tramp try to connect

we expect tramp to connect only when we have:
/sudo:: and not before (i.e before entering the second ":").

Yes maybe.

But I have no problem here with my code (anything), 
it seem the problem is in ido and/or icomplete.

And to implement completion on method/users/hostname, `non-essential' is
no help for me, i will use something else later, as described in
one of precedent post.
Anyway i am glad to now existence of `non-essential'.
Thanks.

Again, where does Tramp try to connect in this case?

When I do C-x C-f /ssh: TAB Tramp does not try to connect to anything,
it just shows me some hostname completion.

I get the same behavior with or without icomplete-mode.  I think we need
you to give us a more specific recipe.

Because this implementation works for vanilla emacs completion, but is
unusable elsewhere. (like try-completion)

I don't understand.  Please be specific:
1- does it try to start a Tramp session?
2- do you want it to try to start a Tramp session?
3- where does it try to connect?

From what I understand you're saying that (1) is true, and that (2) is
false, whereas in my experience (1) is false.
Also I don't know what it means for Tramp to "try to connect to nowhere".

"vanilla Emacs completion" uses try-completion, so you must thinking of
some other "elsewhere".  What is that other "elsewhere"?

Are you saying that the problem you reported only affects older Emacsen
and has been fixed in the trunk?

To e.g "/ssh:" which is an incomplete address 
and hang indefinitely.
Just like when you do C-x C-f and enter in prompt /ssh: and press RET.

External libraries like anything create completion modes that replace
most completing-read's.
So the completing-read that use all-completions are ok, but the one that
use try-completion are usable only in a Vanilla emacs environment.

No i say completion in Emacs is made differently so it is acceptable,
though it should not hang like described above.
(Here i display in buffer "Invalid tramp file name" and wait user enter
something correct before trying to connect with tramp to this invalid
name).

What i was suggesting is just a different implementation that would
work more safely in all case.
It's what i did in anything except for hostname completion which is not
done yet. (see precedents posts).

I'm beginning to understand.  Indeed, I see that C-x C-f /ssh: RET and
C-x C-f /sudo: RET both behave oddly (they try to connect to hosts `ssh'
or `sudo').  They don't hang for me, but arguably they should not even
try to treat the "ssh" or "sudo" as a hostname.

Michael?

So you're saying that Tramp handles try-completion subtly differently from
all-completions and that your completion code uses try-completion
subtly differently from the way vanilla completion uses it.

I wonder if the first pat is indeed true, and if so why (could be that
it was a hack to try and distinguish icomplete/ido from TAB, back when
we didn't have non-essential).

As for the second part, I have no reason to doubt you, tho I'd be
interested to try and understand how it is different and why that
triggers the problem.  My guess is that you're doing something similar
to lightning completion (i.e., roughly, call minibuffer-complete after
every key-press), yet ...

..Oh, wait, I think I see something interesting:

  % emacs -Q
  C-x C-f /ssh: TAB RET RET
  C-x C-f /ssh: TAB

The first C-x C-f just ends up loading Tramp then trying to connect to
`ssh' and fail, but it also changes something inside Tramp because on
the second C-x C-f the TAB causes Tramp to try to connect some "default"
host (apparently it uses the first host in my ~/.ssh/config, and
subsequent attempts will try subsequent hosts in that file).

We don't want that, and your completion scheme might be bumping into
this very problem.

Michael?

Why that? It is legal to have a hostname "ssh". Anybody can create such
an entry in ~/.ssh/config. Or an alias in /etc/hosts, or a DNS alias.

What we are speaking about is filename completion. If you enter RET, we
do not speak about completion anymore, but opening a file "/ssh:", using
Tramp's default connection method, which ought to be "scp" on GNU/Linux.

Tramp has always the problem to understand what "C-x C-f /ssh: TAB"
means. This is due to the syntactic ambiguity of Tramp's file names
("ssh" can be both in this case, a method or a hostname).

[Side remark: with XEmacs, we use another syntax. There aren't such
 problems. But I guess it is much too late to change the syntax for GNU
 Emacs.]

I will try to change Tramp's completion algorithm such a way, that in
case "C-x C-f /foo: TAB" is pressed, and "foo" is a method found in
(mapcar 'car tramp-methods), Tramp does not check "foo" being a
hostname. This shall be sufficient for the incrimed case.

Yeah, I do (no pun intended).  See the other report I made today.
Again, I'm not sure it's *technically* Tramp's fault, but I think Tramp
should probably be more resilient to whatever ido is doing.

I haven't done this change (yet), it's more complex than expected.

But during tests I've found another weakness that has led to the error
you have observed. I've committed a patch, maybe you can check?

Sorry for late reply, i had network problems.
I think we misunderstand here, i have no real problems with tramp, i
have made my anything code working with tramp as i want, only
method/hostname completion are not implemented yet, but all is working
fine here.
I was suggesting at first using a tramp-file-name-regexp that detect a
tramp name only after the second ":" (what i do here in anything),
because i thought you had problems with ido, but it seem you have fixed
all, so i think it's ok.
For my use case in anything, i can deal with the actual tramp code, no
problems.
 
Thanks.

Good to know. So I will concentrate in this bug report on what's left
from Dave's problems with ido.

I recommend not to use an own `tramp-file-name-regexp'. There could
always be problems when Tramp is changing it, and there are in fact 3
different syntax notations for remote file names, which are supported by
Tramp.

Have you tried to apply `non-essential' instead?

It sounds like you're saying that you managed to work around

I do not replace `tramp-file-name-regexp' by another value, i use a let
bound regexp similar to `tramp-file-name-regexp' but named differently.

And then i reuse `tramp-file-name-regexp' where needed.

Use `anything-find-files' to try your tramp with anything completion ;-)

It is no help for my use case.

Thanks.

Hi Thierry,

I've just committed a patch for ido.el, which removes explicit loading
of Tramp. Autoloads shall be sufficient.

This is all what could be done inside ido, IMHO. I've seen your other
report on the Tramp ML, and I'm working on this. Therefore, I believe we
can close *this* bug report.

Do you agree?

Best regards, Michael.

Thanks to take anything.el in consideration.
