Clearly the problem had to be my particular debian setup.
My first port of call was to change the window manager I have been
using, from xfce running on openbox to xfwm4.
This completely removed the problem, and all is now working as it
should, although I am at a loss in terms of knowing why openbox should
be a problem---it has until very recently been my desktop of choice.
(Obviously, some modification in the openbox version I use.)
That's pretty strange... If you ever find out why openbox does not like this
dialog, there may be something we have to fix on our side.
I have, apparently, been wasting your time, but all I can say is thank
you---without confirmation that the file worked, I would not have found
what was causing my problem.
Don't worry, it is important for us to understand those problems. We've had
several instances where weeks of head scratching lead to discover an actual
bug in our code.
+1 on the contrary, thank you Bruce for helping investigate this issue!
Even though you know the issue has to do with openbox, I think it is
important to know which change in LyX's code triggered the issue.
In my opinion the way to proceed is a git bisect. Now that you have git
set up and you have compiled 2.1.0, here is the procedure:
# will remove any extra files
git clean -xdf
git bisect start
# "good" because you cannot reproduce the bug
git bisect good 2.1.0
# "bad" because you can reproduce the bug
git bisect bad 2.2.0rc1
# chunk label A
# now compile and run LyX, e.g.
# use make -j4 or whatever to speed things up
# sometimes the compilation fails, see below for details on what to do
./autogen.sh && ./configure && make && ./src/lyx
# go have a tea, watch a movie, or eat some ice cream feeling happy with
# yourself because your computer is doing important work so this is not
# wasted time.
# When LyX has compiled (if it compiled successfully), it will
# automatically start (because of the ./src/lyx) so you don't need to
# constantly check back on the terminal.
# now do your manual test of "can you reproduce the bug" ?
# if you do see the bug, then this is a "bad" commit and you run
# git bisect bad
# if you do not see the bug, then this is a "good commit" and you run
# git bisect good
# if you were not able to compile a certain commit, you do not know if
# it is "good" or "bad". In this case do
# git bisect skip
# after the above, you will be taken to a new commit to test whether
# good or bad.
# to be sure, I recommend doing the following:
# this will make sure you do a fresh compile every time.
git clean -xdf
# now go up to chunk label A and start again.
# the output that git provides, should be understandable. It will tell
# you how many times you will need to compile and test, and it will tell
# you which commit is the "bad" one.
Please ask on the list if you have questions.
Scott
When running
git bisect bad 2.2.0rc1
I receive the following message:
Please, commit your changes or stash them before you can switch branches.
Aborting
Please advise.
OK, did you make any changes to the LyX source code? If so, make sure
you back them up. Then, in the instructions above, add
git reset --hard
to every instruction just before every
git clean -xdf
You might need to do
git bisect reset
If you see another problem, post the output (showing if some of the
commands worked and where you are at in the instructions when you run
into the problem).
Thanks,
Scott
Ok, I started the whole process over, from the beginning, i.e., I did a
fresh clone of the git files, and followed your procedure.
The first compilation resulted in the following version
version 2.2.0dev
Built from git commit hash 7f0ac093
which was good. I input the command you gave, and received the following:
bruce@debian:~/lyx$ git bisect good
Bisecting: 755 revisions left to test after this (roughly 10 steps)

A hard reset returns me to the already tested hash, and so achieves nothing.
And a bisect reset returns me to 2.1.0.
Clearly there is something I need to do before inputing the "bisect good"
command, or perhaps there is something I need to install.
In any event, without knowledge which I do not currently possess, I cannot
continue.
Try doing the "git reset --hard" before "git bisect good".
Scott
"git reset --hard" takes me back to the original head, from which the
problem continues.
Before I arrived at the same message I noted above, I managed to test:
LyX Version 2.2.0dev
(not released yet)
Built from git commit hash 7f0ac093
and it was good.
Reading the git manual and various pages of information has not helped me to
work out what is happening, so I am going to have to leave it here, for now.
OK let's try a fresh start with updated instructions. Please try the
following, and if you get an error, post all of the output (beginning
from the start of the instructions listed below):
# first back up any changees in the LyX source in case you want to keep
# anything. Ask if you need clarification.
# will remove any extra files, and any changes to the LyX source
git clean -xdf
git reset --hard
# possible need the following command if you had started a bisect before
# and want to start over:
git bisect reset
git bisect start
# "good" because you cannot reproduce the bug
git bisect good 2.1.0
# "bad" because you can reproduce the bug
git bisect bad 2.2.0rc1
# chunk label A
# now compile and run LyX, e.g.
# use make -j4 or whatever to speed things up
# sometimes the compilation fails, see below for details on what to
# do
./autogen.sh && ./configure && make && ./src/lyx
# go have a tea, watch a movie, or eat some ice cream feeling happy with
# yourself because your computer is doing important work so this is not
# wasted time.
# When LyX has compiled (if it compiled successfully), it will
# automatically start (because of the ./src/lyx) so you don't need to
# constantly check back on the terminal.
git clean -xdf
git reset --hard
# now do your manual test of "can you reproduce the bug" ?
# if you do see the bug, then this is a "bad" commit and you run
# git bisect bad
# if you do not see the bug, then this is a "good commit" and you run

# git bisect skip
# after the above, you will be taken to a new commit to test whether

Scott
Ok, first question: What does "chunk label A" refer to.
It is just a way that I can refer to a previous piece of code. If it is
easier to understand, delete the line
# chunk label A
and where it says
# now go up to "chunk label A" and start again.
instead change that to be
now go back to to the line in the instructions that starts with
"now compile and run LyX"
Does that make sense?
I'm sorry for the unclear instructions. Thanks for sticking with it.
Scott
No problems Scott, I assumed that that was what you meant, but thought I
would check simply because I had made a hash (pun intended) of the process.
It is, however, now proceeding nicely, and I have found the first commit
that caused the problem. (d4ca8d74)
I assume that at the end of the process bisect will provide a report for
me to send? Or is there a log file somewhere (I can't see it, offhand),
which will provide the information required?
Cheers
Bruce
