Before the change, the `notmuch-show-insert-text/plain-hook' was
given only the `depth' argument. The patch adds another one -
the message. Currently, the new message argument is not used by
any on the hooks. But it will be used later to get access to
message invisibility specs when wash buttons are inserted.

Before the change, message and citation invisibility overlays
conflicted: if some citation is made visible and then the whole
message is hidden, that citation remained visible. This happened
because the citation's overlay has an invisible property which
takes priority over the message overlay. The message
invisibility spec does not affect citation visibility, it is
determined solely by the citation overlay invisibility spec.
Hence, if citation is made visible, it is not hidden by message
invisibility spec.
The patch changes citation overlay invisibility property to be a
list which contains both the citation and the message
invisibility specs. This makes the citation invisible if either
of them is added to the `buffer-invisibility-spec'. Note that
all citation visibility states are "restored" when the message
hidden and shown again.

That sounds like quite a bug. I'd love to see this series also add a
test case for that.

I am not sure how it is best to test this. The common `printc' method
for emacs tests does not work, because it prints invisible parts as
well. We need either to find a way to print only visible text on the
console, or test it inside emacs somehow. Any suggestions?
Note that this is exactly the patch that hits the isearch emacs bug. Do
I understand correctly that you are ready to push the series despite of
it (given that we have a test)?

Unfortunately, I don't have a good plan here. I delayed implementing any
automated testing at all of the emacs interface precisely because of
this problem. It's seems to me that surely emacs must have some built-in
mechanism for copying the visible portion of a block of text, but I've
not been able to find it.
We could do something cheesy (and slow) by marching through the buffer
character-by-character in elisp and testing for visibility, but the
emacs tests are already the slowest part of "make test"[*] so that would
be obnoxious.

Breaking isearch would be really unfortunate. That's a really nice
feature of the emacs frontend currently.
So I would notice that breakage, (while I've apparently never before
noticed the breakage of having visible citations in a hidden message).
So no, I'm not saying I'm ready to push the series while emacs is broken.

Well, emacs trunk is not broken :) The bug is in lisp code, so you can
fix it in .emacs by redefining `isearch-range-invisible' function. I do
that now.
I do not think I will make myself work on the test until it is likely to
be pushed. I will try to not to forget about it, so sometime later I
may be back to it :)
Please consider pushing other patches from the series. They do not fix
any bug, but do simplify the code. The last patch uses list for
invisible overlay property as well. But it does not break isearch
because we do not search in hidden messages.
BTW would be nice to have a set of known-to-fail tests, i.e. bugs that
are not fixed yet. If we had it, the above test could be implemented
and committed before we have the fix pushed.

This is possible as long as tests do not affect each other. Would be a
nice improvement.

Oh, in that case we can fix this is notmuch emacs lisp by just defining
and using a fixed function. Is the broken function something we're
calling directly? Or is it being called indirectly? (being called by
other emacs lisp code that we are calling)?
If we can incorporate the fix, that would be great.

Hmmm... we should probably do that. I'd like isearch in notmuch to
search anything that is hidden.

We do! Use test_expect_equal_failure (yes, the name is horrible!)
instead of test_expect_equal and you should get what you want.

It is called indirectly. What is the best way to fix it? I imagine
that we can replace `isearch-range-invisible' function with another one,
which would call the fixed function if some special variable is set, or
if we are searching in a notmuch-show view. Otherwise it would call the
original function.

That is easy to fix. I can do that once we are done with this stuff.

I'm not sure what the best approach would be. I'd like to be a good
"emacs citizen" but I don't know what the best way to do that is here.
If we can predict what the first emacs release will be that contains the
fix, then we could restrict our kludge here to older, unfixed
emacs. That would help avoid some problems with "bad citizenship here".
I'm willing to take whatever you this is best here.

I have just send two more patches to this thread. One with new tests.
Another with a workaround for the bug. The workaround should not break
anything since it affects only notmuch-show mode.

Thanks!
I love committing tests that demonstrate broken code before committing
fixes. As it happened here, I committed these two new patches thinking I
had previously committed the earlier patches in the series. Fortunately,
the failure of the test pointed out that I was missing the actual fix.
I also really like the workaround to avoid regressing functionality
because of an emacs bug.
Well done, Dmitry. I've now pushed out everything in this series.

I know you prefer tests to go before patches and I agree with that. But
most of the time I do tests after coding. I do not know an easy way to
reorder patches in git. (Also I do not know how to amend an old patch,
wish more darcs features in git.) Hopefully it is not a big trouble for
you to reorder the patches when applying.

Hey, Dmitry. I usually just pop in to a new branch rooted before my new
patch series, and then cherry-pick the new patches onto the branch in
the order I want (eg. tests first, etc.).
jamie.

Yes, I do that order almost exclusively as well.

Fortunately, git has a great feature here for both use cases, (git
rebase -i). Here's the simple recipe:
* Find a bug, fix a bug, commit
* Write a test case, commit
* Run the following command:
git rebase -i origin/master
At this point you'll be presented with an editor window giving one line
for each commit that you have made since origin/master. You can reorder
these lines however you'd like. When you save and exit the editor, the
commits will be applied in the order you saved.
If there are any conflicts due to the re-ordering, then git rebase will
stop and tell you what to do, which will be:
* Resolve the conflict
* Run "git add" on the files you edited
* Run "git rebase --continue"
Also, back when editing the original list of commits, you can change the
word "apply" next to any particular commit to change what happens when
applying it. If you change that to "reword" you'll be given an editor
window to edit the commit message. If you use "edit" then you'll be
dropped to a shell where you can:
* Edit the code
* Test as necessary
* Run "git commit --amend"
* Run "git rebase --continue"
I absolutely love "git rebase -i". It's one of my favorite
user-interface features in git.
> wish more darcs features in git.
I don't know about "git rebase -i", but I think I heard that "git add
-i", (interactively add some portions of the dirty working tree to the
index to be committed). I think the menu-based interface of "git add -i"
is particularly clunky. But I love the trimmed-down interface of "git
add -p" which simply prompts one-patch-hunk-at-a-time for pieces to add
to the next commit. It even supports splitting a hunk, (or even manually
editing the patch to trim it down!). It's pretty slick stuff.
So there are some git tips that might be useful.
> Thanks.
You're quite welcome. Thanks for all the great work. Please keep it up!

Thanks for this. I did not know about interactive mode in rebase.
This is some sort of replacement for darcs amend (which allows editing
any patch, not just the last one).

Yes, "add -i" is ugl... confusing, but "add -p" is very nice. A great
feature of darcs picked up by git.

Before the patch, message, headers and hidden citation overlays
had zero priority. All these overlay have `invisible' property.
Emacs documentation says that we should not make assumptions
about which overlay will prevail when they have the same priority
[1]. It happens to work as we need, but we should not rely on
undocumented behavior.

Before the change, headers and message visibility functions took
extra care to correctly set `buffer-invisibility-spec'. This was
needed because headers overlay `invisible' property had only
headers' invisibility spec. So visibility of headers was
determined only by the headers invisibility spec. The patch sets
headers overlay `invisible' property a list with both the headers
and the message invisibility spec. This makes headers invisible
if either of them is added to the `buffer-invisibility-spec' and
allows to simplify the code.

`notmuch-isearch-range-invisible' instead of the original

I've screwed up the commit message because of a line starting with '#'.
Attach is an amended patch.

Subject: [PATCH] Workaround for Emacs bug #8721.
The patch adds `notmuch-isearch-range-invisible' function which
is the same as `isearch-range-invisible' but with fixed Emacs bug
#8721. Advice added for `isearch-range-invisible' which calls
`notmuch-isearch-range-invisible' instead of the original
`isearch-range-invisible' when in `notmuch-show-mode'.

This is an amended patch which uses `isearch-range-invisible' from Emacs
trunk r104393 (includes the second patch from #8721).
Regards,
