There's a regression in 25.1 introduced by 1e04ea9 (although that seems
to also have fixed an issue): Now tramp-histfile-override is set to
".tramp_history", which is good, but I would expect it to be created in
$HOME on remote hosts.
Instead when I e.g.:
1. C-x C-f //ssh:<hostname>:/usr/local/git_tree/sysadmin/
2. Run e.g. magit to make a commit
3. I end up with:
$ echo $PWD/.tramp_history
/usr/local/git_tree/sysadmin/.tramp_history
$ wc -l !$
wc -l $PWD/.tramp_history
34 /usr/local/git_tree/sysadmin/.tramp_history
From reading https://debbugs.gnu.org/cgi/bugreport.cgi?bug=20446 and
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=19731#56 this seems like
an unintended bug.
Just setting:
(setq tramp-histfile-override "~/.tramp_history")
Works for me. Now it's always created in ~.

Most of the shells I know off use the home directory, when you specify
just the relative file name ".tramp_history".

I have thought about this, when I was fixing bug#19731. Unfortunately,
there exist shells which cannot expand "~/". Other shells cannot expand
"$HOME/". So I really don't know a robust default we could offer.
Maybe one should give this problem more emphasis in the Tramp
manual. But who reads manuals?
Best regards, Michael.

Michael, does the above mean this bug should be closed as wontfix? It
currently blocks a release, so I'd like to resolve this some way soon.
Thanks.

I'm the reporter, so I obviously have a dog in this fight, but I don't
think that makes sense. This whole facility introduced in the emacs-25
series still seems really broken since its introduction, and the
various regressions reported have just resulted in other regressions
taking their place, the latest one being discussed in this ticket.
Here's a Git history showing the back & forth this has gone through:
git log --reverse -p -Gtramp-histfile-override -- 'lisp/net/*tramp*.el'
I might have read those commits incorrectly, but it seems to me that:
* In emacs-24 there was no way to have a Tramp history file, we'd
just specify a HISTFILE=/dev/null environment variable.
* 9be1538 added an option to change that, so you could have a history
file as a file, defaulting to /dev/null, but they way it was
implemented caused it to unlink /dev/null, as reported in
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=19731
* So Michael patched it to make 'unset an option, which was
implemented in 6f8372d, as far as I can tell at this point the
facility worked the way it did in emacs-24 again. I.e. no history by
default, but no regression with unlinking /dev/null
* 'unset was made the default by Michael in 954ca0f, but just a few
hours later this was set to t instead in c10828b, which does the same
thing as 'unset according to the commit message. I.e. just an internal
refactoring. This was followed-up by 24fa4ff to refactor it some more.
* It was then changed from t to ".tramp_history" in 1e04ea9. The
commit message says to fix
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=20446 but I don't see
how it could eat the bash history if it's set to not have any history
file by default.
* Now because it's ".tramp_history" and not "~/.tramp_history" it gets
created in random non-~ directories you open with tramp, but more
importantly, and I didn't realize this in my initial report, the shell
history *might be shared between multiple users*, which seems like a
bad security issue.
It seems to me that the best solution to this whole problem is to set
it to "t" again which would return to the non-history days of
emacs-24, since apparently using ~ can't be counted on.
In addition, depending on the bug with history potentially being
shared between users now that it's being dumped in random potentially
shared FS directories they open with tramp, changing this to
".tramp_history" might have caused a security issue worth of a CVE,
but I haven't investigated that, but we *certainly* went from no
history by default in emacs-24 to history littered in potentially
world readable directories in emacs-25.
The permissions on the file itself might have mitigated data leakage
in some cases, but in those cases it would have blocked other Emacs
users from recording their shell history. In addition not all remote
FSs tramp supports working with can be relied upon to obey HISTFILE
permissions.

I'm also unhappy about this story. I really would like to use a proper
and robust default value for this. But there isn't one so far.

This was introduced back in 2014. Before this change, HISFILE was unset
somewhere else in the initialization hand-shake, but at a later
point. It didn't work properly then.

Bug#19371 has reported, that there is a bash bug
<https://bbs.archlinux.org/viewtopic.php?pid=1397412#p1397412> which has
this effect. It is no Tramp error, and I would regard this setting still
be the best one if possible. But due to this bash bug, this setting
would damage the remote system. So we cannot use "/dev/null" as default,
even if the bash bug has been fixed. There will still be system in the
wild with this bug.

Yes.

Glenn did report, that in his use case unsetting HISTFILE has changed
his ~/.bash_history to a zero size. Not acceptable, and again a special
behaviour of bash :-(
So the only solution I could thing about is setting this variable to a
Tramp specific value.

"~/.tramp_history" would be the obvious choice, but "~/" is not
guaranteed to exist. An example is hydra, were the tests failed with
this setting.

How do you want explain it to bash users like Glenn? Their history file
will get lost, again.

I still don't understand why the ".tramp_history" file is spread over
the file system. This setting is apllied immediately after connecting to
the remote host. I would assume that one lands in the home directory
there; ".tramp_history" should be expanded relatively to that directory.
Could you show hot it happens to you that it is expanded to another
place? Pls run Tramp from scratch, after increasing the debug level by
(setq tramp-verbose 6)
There will be a Tramp debug buffer, which might tell us what happens.
Best regards, Michael.

Thanks for all the follow-up details. I mainly included all of that to
get all this straight in my head, but I was apparently wrong about it
being viable to revert to the old behavior vis-a-vis unlinking
/dev/null on those old systems.

All I'm doing is e.g.:
1. C-x C-f //ssh:puppet-staging:/etc/puppet/environment/aearnfjord/puppet RET
2. Run some command e.g. M-x grep <hi>
3. This results in:
$ wc -l $PWD/.tramp_history
39 /etc/puppet/environments/aearnfjord/puppet/.tramp_history
I've snipped away the parts I think are irrelevant because it's very
verbose, but this hopefully the relevant tramp-verbose=6 output:
[I don't have an existing tramp connection at this point, so it connects]

OK, so this is about running an asynchronous process on the remote
host. This shall help me to reproduce it locally, thanks for the recipe.
Best regards, Michael.

If you mean the M-x grep from the .tramp_history (in that
/etc/puppet/... directory) it starts much earlier than that, i.e.
Tramp's own post-connection commands go to that file, and then the
last command is my M-x grep:
$ cat .tramp_history

Thanks. So it is related to `tramp-open-shell', which comes just prior
these commands.
I've tried it with several configurations, but I could not reproduce the
problem locally. I suppose this behaviour is related to the used shell
on the remote host. What is /bin/sh on your remote machine?
So again, could you pls start a new Emacs, set tramp-verbose to 6, and
connect to the remote host where it happens?. And I need the full debug
buffer then, because there are a lot of other information which could
tell us what's up. If you have privacy concerns showing this publicly,
pls send it to me directly.
Best regards, Michael.

For the records, today I could reproduce the problem. I had to set
/bin/bash explicitely as remote shell.
Let's see, whether I could find a proper solution, compliant to all
bug#24478, bug#20446, bug#19731, bug#17295. And it is always bash, which
causes problems!
Best regards, Michael.

Hi, sorry about not getting back to you earlier on this bug, so just
to confirm you don't need to be to reproduce this anymore?
The system I'm ssh-ing into is a CentOS (a RedHat derivative) machine,
on RHEL/CentOS/Fedora:
$ file /bin/sh
/bin/sh: symbolic link to `bash'
$ rpm -qf /bin/sh
bash-4.2.46-20.el7_2.x86_64
I.e. their /bin/sh is always bash, as opposed to say the more minimal
dash shell on Debian.

No, I shall be able to work on this with the information I could

Indeed. All the bugs I've quoted were related to bash.
Best regards, Michael.

Well, I've partly reverted the fix for bug#20446. This shall fix the
problem for you. See appended patch.
Glenn, you have reported bug#20446. I believe that I haven't
reintroduced your problem, but I would appreciate pretty much if you
could cross-check this. The point is NOT to set $HISTFILESIZE.
Best regards, Michael.

Ping. I would really like to get your feedback, before I push the patch
to the emacs-25 branch.

Since I couldn't apply the other change, setting
`tramp-histfile-override' to t, I've changed it now to
"~/.tramp_history". Plus a short test whether this (or something else
the user decides) is a proper setting.
Hope this fixes the problem finally. Could you, pls, crosscheck in the
emacs-25 branch?
Best regards, Michael.

Looks good to me. The ~/.tramp_history value you changed it to has
been what I've been setting this to locally to work around the issue.
Thanks!

I know. But I also want to ensure, that the additional code does not
break anything.
Hmm, so what. I mark this bug as closed, hoping the problem does not
appear, again. And I'll watch hydra next days; being curious whether it
breaks there.
