Re: Bug: ob-R.el breaks when :session is specified

2022-05-15 Thread Christian Heinrich
Hi Charles,

ob-R.el requires ess and the (require 'package) makes sure the ~/.emacs.d/elpa/ 
directory was added
to the load path. But you were somewhat right already: the loaded ESS was years 
old and caused the
issue.

Thanks for your help!

Hi Jeremie,

thank you for providing this example!

The ess that was found in the load path was years old and once updated, all 
issues were resolved. In
fact, my so-called minimum init still used (require 'package) and I didn't even 
think about ESS
causing this trouble.

It's now a bit clearer how to build a real minimum init - thank you!

This is hence resolved.

Many thanks for reporting back.  I updated to gcdbb1c and it is still working 
fine.

My minimum working example is the following. From the org-mode root directory,

$ emacs -Q -L ./lisp -l org  -l ~/ess-barebone.el

where ~/ess-barebone.el is the following:

#+begin_src  elisp
(add-to-list 'load-path "/home/djj/.emacs.d/elpa/ess-20220125.2207/")
(require 'ess-r-mode)

 (org-babel-do-load-languages
   'org-babel-load-languages
   '((R . t)))

(setq org-confirm-babel-evaluate nil)
#+end_src

Note that I'm still using a rather old ess version. Could you please try
with the above configuration? Note that I am using a rather old ess
version but the I haven't experienced issues with the newer one.

Best regards
Jeremie

Just spitballing here:

Have you tried instrumenting `org-babel-R-evaluate-session'? 

Maybe watching changes made to the session buffer on first evaluation and 
comparing to subsequent evals helps.

Re: Bug: ob-R.el breaks when :session is specified

2022-05-15 Thread Christian Heinrich
Hi Jeremie,

I just tested with

 Org mode version 9.5.3 (release_9.5.3-504-gcdbb1c @
/home/heinrich/.emacs.d/straight/repos/org/lisp/)

using

GNU Emacs 27.1 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.30, cairo 
version 1.16.0) of 2021-
11-27, modified by Debian

I am on Debian Testing and that is the default emacs version.

Using the unmodified org (git hash from above) I get the following messages 
when executing a src
block with R:

   executing R code block...
   Loading ‘ess-bugs-l’: unescaped character literals `?(', `?)' detected, 
`?\(', `?\)' expected!
   Type C-h m for help on ESS version 15.09
   ess-tracebug mode enabled
   Quit
   Package cl is deprecated
   
Note that the "Quit" is me pressing Ctrl-g after a few seconds.

Removing the commit in question makes the block return instantaneously:

   executing R code block...
   Loading ‘ess-bugs-l’: unescaped character literals `?(', `?)' detected, 
`?\(', `?\)' expected!
   Type C-h m for help on ESS version 15.09
   ess-tracebug mode enabled
   Code block evaluation complete.
   Package cl is deprecated
   
I anticipated that this would not be obvious, since this feature is used too 
much to go unnoticed for
two years - but I am clueless as to how I should continue with debugging...

Thanks for your help!

Hello Christian,

Thanks for reporting but I cannot reproduce the bug with the org and
emacs version below.

Org mode version 9.5.3 (release_9.5.3-467-g2bd34e @
/home/djj/src/org-mode/lisp/)
GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.24) of

Can you please let me know which version of org-mode you are actually
using?

Ihor, many thanks for checking.

Best regards,

Re: Bug: ob-R.el breaks when :session is specified

Hi,

thanks, that's what I had expected since that patch has been around for a long 
time.

I run 

 emacs -q --load /tmp/init.el --file=/tmp/test.org 

with my /tmp/init.el being only

> (require 'package)
> (package-initialize)

I hope this constitutes a minimal example for a config - please correct me if 
I'm wrong.

My test.org contains the source block I had already posted:

#+begin_src R :results output :session *R* :exports both
  a <- 10
  a
#+end_src

Any ideas how I could continue to debug this? If I just remove that patch, 
everything works
flawlessly for me but I would like to figure out what causes the issues.

Thanks!

I tried you example using Emacs >=26 and it works just fine.

Bug: ob-R.el breaks when :session is specified

2022-05-15 Thread Christian Heinrich
Hi there,

I got back to an org file after upgrading to the latest release of org-mode and 
tried executing the
contained R source blocks. Unfortunately, emacs got stuck in the execution and 
was blocked; I had to
exit using C-g.

Here's a minimal example src block that causes emacs to get stuck:

#+begin_src R :results output :session *R* :exports both
  a <- 10
  a
#+end_src

R itself does start and the code is also executed correctly. However, the 
output from that session
is apparently not returned to emacs or the buffer.

When removing the :session argument it executes and returns as expected.

When bisecting this issue, I found that this commit causes it:
ac8c009e006197d2dad226dbe822d450aec23d23

lisp/ob-R.el: Fix session output with substrings matching prompts

Reverting it fixes the issue for earlier release (9.5.3) as well as for the 
current main branch.

The (with-current-buffer session ... ) somehow seems to break it for me, but I 
am unsure why no one
else here seems to experience this as the commit is from 2020?

Any suggestions?

Thanks!
Christian
