Aloha Jambunathan K.,
Very many thanks for this information. I have Org-mode version
7.01trans
(release_7.01h.880.g7531f). I take it the problem I'm having is
due to a relatively recent change
to Org-mode. If there is anything I can do to help isolate the
problem, please let me know.
Tom,
If you have the time and the inclination, you might try bisecting
your
way through. Bisecting org-mode problems is actually a very good way
to
practice because the turnaround time is very small.
Prerequisites:
* you have a clone of the org-mode git repository.
* you have an org test file.
Steps:
* [optional, but it makes me feel a little safer] create a test
branch
and switch to it:
git checkout -b test-branch master
* I clean out all the compiled files while doing a bisection: it's
quicker
than regenerating them every time and I don't have to worry (much)
about
emacs loading a wayward .elc file:
make clean
* start the bisection and tell git which commit is known good and
which is known bad:
git bisect start
# current version is bad
git bisect bad
# release_7.01h was good - I got the name with ``git tag''
git bisect good release_7.01h
That checks out a revision half-way in between the bad and good
commits: since
there are about 900 commits in between, you'll be at approx the 450-
mark and it
should take about 10 bisections to get it down to a single commit.
* LOOP Now all you have to do is repeat the following steps:
# since you did ``make clean'' you don't have to worry about .elc
files
# just reload all the .el files.
M-x org-reload
visit your org test file, export to LaTeX, check for \href/
\hyperref (or
whatever other telltale sign shows badness/goodness).
# tell git about it
git bisect good *OR* git bisect bad
This last step will check out another revision and in about 10
repetitions
of the loop, you are done.
* Tell git you are done, so it can clean up:
git bisect reset
Theoretically, you could do all of this in your master branch
without
creating a test-branch and this last step will reset everything to
the
way it was before ``git start''.
* Post the offending commit to the list.
* Get back to your master branch:
git checkout master
* If you created a test-branch, clean it out:
git branch -d test-branch
* [Optional] Recreate your .elc files and reload them:
make
M-x org-reload
And that's it: a half-hour of fun and games. Unless of course, you
hit upon a revision that is neither good nor bad (in the above
restricted
sense): you might get some other problem that prevents you from
being
able to answer. That might or might not be easy to resolve, so I'll
leave that as an advanced topic (truth be told, I came up against
this
situation a couple of days ago and I didn't know how to proceed: so
it's ignorance more than anything else that prevents me from saying
anything more).
If you want to try, I'd be happy to answer questions - I might try
the
bisection later on tonight myself in any case. And btw, this is of
course archeology of a different (and much easier) kind, so I
imagine
you'll take to it like a fish in water :-)
HTH,
Nick
