refresh not working for org-mode from git

refresh not working for org-mode from git

[Colin Baxter]

Recently, if I use C-c C-x ! to refresh org-mode after a git pull, I get an
error. I then have to close down emacs and launch again. This rather
defeats the object of C-c C-x !. This appears to have happened only recently

The Backtrace is

I also receive a warning, copied below. I do not use 'packages' but use
org-mode from a git repository and have done so with no previous issues.

--8<---------------cut here---------------start------------->8---
⛔ Warning (emacs): Org version mismatch.  Make sure that correct `load-path' is set early in init.el
This warning usually appears when a built-in Org version is loaded
prior to the more recent Org version.

Version mismatch is commonly encountered in the following situations:
1. Emacs is loaded using literate Org config and more recent Org
   version is loaded inside the file loaded by `org-babel-load-file'.
   `org-babel-load-file' triggers the built-in Org version clashing
   the newer Org version attempted to be loaded later.

   It is recommended to move the Org loading code before the
   `org-babel-load-file' call.

2. New Org version is loaded manually by setting `load-path', but some
   other package depending on Org is loaded before the `load-path' is
   configured.
   This "other package" is triggering built-in Org version, again
   causing the version mismatch.

   It is recommended to set `load-path' as early in the config as
   possible.

3. New Org version is loaded using straight.el package manager and
   other package depending on Org is loaded before straight triggers
   loading of the newer Org version.

   It is recommended to put
    (straight-use-package 'org)
   early in the config.  Ideally, right after the straight.el
   bootstrap.  Moving `use-package' :straight declaration may not be
   sufficient if the corresponding `use-package' statement is
   deferring the loading.

I wasn't aware that command even existed. However, I suspect it will
cause issues in your use case. I'm not sure it is a good command to
actually have given the complexities associated with getting a clean org
build.

In many cases, you may not run into issues - especially if you do a git
pull frequently. However, I can see various scenarios which will lead to
inconsistent builds. I suspect the error you are seeing is the result of
recent work to try and identify builds which are likely to result in an
inconsistent 'mixed' version build. Detecting such scenarios is
difficult and relies on a number of heuristics, one of which is to flag
a problem if the loaded version and the target build version don't
match.  

A lot would depend on how you build (re-compile) org mode after doing a
git pull. If you compile it in a separate Emacs instance, you should
have less issues and reloading after the build will likely
work. However, if your trying to build org mode within the running Emacs
where you have already loaded org mode, I suspect you will run into
issues. You have a slight 'chicken and egg' issue and will run into
similar issues as the common mixed build problems.

One thing which might work would be to ensure you run the reload command
with the option to load from uncompiled sources BEFORE you run the build
process and then re-run the load command after the build (loading
compiled versions this time).

I have no idea how things might break given the new native compilation
modes in Emacs. I suspect it will cause all sorts of issue with your
workflow.

Personally, I always update org in a fresh instance of Emacs (before any
org functionality is loaded) and I would always restart Emacs after
updating a major packages like org mode. I'm not sure why we have the
reload command - I suspect it may be a hang over from earlier attempts
to work around the mixed build problem. I do suspect that given new
native compilation modes and the additional complexity ths can cause,
combined with increasing org mode complexity, the notion of being able
to pull down a new version, build and reload it within one emacs
instance is perhaps flawed or at the very least, is more complex than
just forcing a reload of org *.elc files. .

Thank you for your detailed reply.

That could well be the case here because the technique used to work up
until quite recently (~2 weeks)

Normally, I use `M-x vc-dir' to update from git, then `M-x compile'
followed by `make clean' and `make'. Finally, update org-mode in the
same emacs with an org-mode buffer present. As I said, it used to work
well.

Yes, I will try that. And I will also ring all the other changes to see
what happens --- if anything.

I have avoided problems here by not using native compilation. I did try
it once in the past, but I didn't think it was worth the candle since
frankly I didn't notice any change in emacs performance, possibly
because I only do simple things with emacs.

Indeed. Emacs seems to have became a rather complex beast in recent
years. Perhaps it was ever thus.

Does it help if you run make after git pull?

I will certainly try that and miss out `make clean', at least in the
first round. As I said in the email to Tim, I will try various
combinations in the build process.

Thank you for your reply.

Re: refresh not working for org-mode from git

The solution is to use `make autoloads'. I suppose that should have been
obvious to me at the beginning. After git pull (`+' in vc-dir) the
working recipe is:

1. rm *.elc
2. Update in org-mode buffer using C-c C-x !
3. make clean
4. make autoloads
5. Check update org-mode via C-c C-x!
6. make
7. Check update org-mode again via C-c C-x!

Some of these steps might not be necessary. I will experiment.

Thank you all again for your help.

Best wishes,

Colin.

FYI, the versions checks are less strict now to work around some Emacs
limitations. See https://list.orgmode.org/orgmode/jwvczc05u7r.fsf-monnier+emacs@gnu.org/

Though I'd still advice to run make autoloads && make if you can.
