Subject: Packages manager not working in WSL emacs-25 build
Date: Sun, 18 Dec 2016 14:07:44 +0100

I recently enabled and installed WSL (Windows Subsystem for Linux) in 
Windows 10 [1] and so tried to build Emacs.

Building Emacs master hangs [2]. So tried emacs-25 branch (+release and 
testing). This branch builds if one adopts the work around suggested in 
/et/PROBLEMS and from the WEB [3]:

echo 0 | sudo tee /proc/sys/kernel/randomize_va_space
./autogen.sh
./configure --prefix=/opt/emacs --without-x
make...

It also seems to work but trying to install packages from MELPA/ELPA fails.

More precisely, in emacs25:

M-x package-list-packages

After the "Package refresh done" I cannot type anything nor I can quit 
(C-x C-c). If I do, for example pressing the down arrow key, in the 
packages buffer I see something like this

[...]
[1]+  Stopped                 emacs25ailable  melpa      No description 
available...
angelo <at> MYPC~   20151026.1233 available  melpa      play 2048 in Emacs..
$ 4clojure           20131014.1507 available  melpa..
[...]

At this point I can only try to kill Emacs. It is as if Emacs were 
reduced to background (C-z), and a 'fg' seems to resurrect it but is 
unusable (I have to close the WSL bash window).

Now, at the moment, enabling and installing WSL installs Ubuntu 14.04 
and one can install other Ubuntu packages with apt-get. So I installed 
the emacs24-nox packages which works without this Packages manager issue!

Then for sanity check I did a build of emacs-24.3.tar.gz (the same 
version offered by WSL-Ubuntu) and it works as expected (also the 
packages Manager).

So the issue seems to regards only emacs-25 branch.


Ciao,
 Angelo.

Yes, and in that case let's declare victory and close out this bug report, as 
the bug is fixed in master and we're not likely to port Emacs 25 to WSL.

I don't understand. Have you commit something to master that fixes this?

Maybe I wasn't clear but the issue regards Emacs > 24.X or, if you 
prefer, Emacs >= 25.X. Also master is affected, at least the build I did 
from master on 20161221_095705 (commit cf6ce9a1fe320ebe5b): this commit 
fixes the issue with the hanging of temacs but not that regarding the 
Packages Manager...

When I opened this bug report the build of master under WSL were not 
fixed, yet. And I didn't expect it would be fixed soon, so I wrote only 
about 25-branch.

I am afraid I wasn't so clear...

IMO, WSL is still a moving target, not yet stabilized enough for us to
attempt to support it on the release branch.

Apparently not. I understood your remark "the issue seems to regards only 
emacs-25 branch" as meaning that the bug occurs only in the emacs-25 branch. If 
the bug (whatever it is) is also present in the master branch, then I will 
reopen the bug report. As Eli says, we don't care about the bug in the emacs-25 
branch.

I have built the last master (e5ef59b87da5) but it has the same packages 
manager issue.

Notice the issue occurs only when Emacs is run in a console. See:

  http://lists.gnu.org/archive/html/emacs-devel/2016-12/msg00813.html

(notice, also, that, for the moment, WSL does not support GUI apps but 
one can works around this installing and running Xming or vcXSrv)

In any case,

Happy Holidays!

Just for the record..

After the upgrade to Win10 Creators Update (clean Reset from 
Anniversary). I reinstalled WSL that now is Ubuntu 16.04 and so Emacs. 
The package installed is 24.5.1.

While with previous installation (WSL-Ubuntu 14.04, Emacs-24.3), Emacs 
worked fine, also with the package manager, now it shows the same issues 
I had with Emacs-25 branch or Emacs-master.. It seems I can't 
install/upgrade Elpa/Melpa packages any more...

The only good news is that it seems that Emacs can be built without the 
"echo 0 | sudo tee /proc/sys/kernel/randomize_va_space" workaround..


Any suggestion about how to upgrade Elpa/Melpa packages? I am using 
~/.emacs.d from previous installation and M-x package-list-packages 
shows that there are packages to be upgraded but trying to type "Ux" 
breaks Emacs.

TIA,
 Angelo.

Lorenzo reports that the package manager is functional on WSL now.  Can
you confirm?

NO, I can't.

Here I always see the same issue with Emacs > 24.3.

But has Lorenzo a recipe to get his results? What Emacs version? How is 
this version built? etc..

*Remember* I am speaking of Emacs running in a console, without X...


Ciao,

Indeed, 24.3 works as expected! I installed sr-speedbar etc.

In the versions greater than that [*], the packages manager does not work!

Please, reread my post..

 Angelo

[*] For example, in current WSL (Win10 CU, Ubunto 16.04),

  apt install emacs[-nox]

installs (from debian repos) 24.5.1 (> 24.3), and here the packages 
manager does not work... the same with the builds of master..
The last version I find it works, in console, is 24.3!

From the above, this doesn't seem to be a bug in Emacs, and has been
fixed in later versions of WSL.  I'm therefore closing this as notabug.
If that's incorrect, please reopen the bug report.
