In order to reproduce the bug, set tags-case-fold-search to t,
completion-ignore-case to nil, and visit a tags table. Type M-. and
enter a prefix for a symbol in the tags table, but with differing case,
then type <tab>.
For example, if the tags table contains the symbol "Abc", type "a".
completion-ignore-case will be set to nil in the *Completions* buffer,
and all relevant symbols will not be shown. In the example, "Abc" will
not be displayed.
I have attached a patch to etags.el that, as far as I can tell, fixes
the bug.

Isn't that a contradiction of sorts? How can we know which of these
two should have precedence?
Thanks.

I think completion-ignore-case should have precedence in this example
because the user called an xref command.
Whether tags are used, or something else, is an implementation detail.
Behavior should be as similar as possible.

I doubt that many users actually set the default value of
completion-ignore-case, it is normally used by binding it during a
completion according to the need of the particular application.
Tags search behavior should follow the documentation and many years of
precedent, regardless of whether xref is the front end. Case folding
during tags search completion, or any other search completion should
be consistent with the search itself.
If you are proposing to add a variable to control case-folding during all xref
searches, analogous to tags-case-fold-search, then I agree.

Please copy me on any messages to which you expect a response.
I have not subscribed to the mailing list.
The only variable I customize is tags-case-fold-search, I leave
completion-ignore-case with the default value. I heartily regret
even mentioning the latter variable, it is a red herring.
There are at least two reasons to change tags-case-fold-search:
1) Some programming languages are not case sensitive in normal use,
eg Common Lisp, Fortran, Cobol, R[45]RS Scheme ... For these languages
case-insensitive search should be the default.
2) For many code bases the rules of CamelCasing are so vague, or their
observance so lax, that it's hard to predict what the capitalization
of an identifier will be. It's useful in these cases to use
completion that is not case sensitive.

Sure. That's the default etiquette here anyway.

Don't regret it because it's entirely pertinent.
So, do we really have meaningful scenarios where the user will want
tags-case-fold-search set to t while completion-ignore-case *should*
remain nil?
I suppose we could add a new method to xref backends just for that, but
we shouldn't do that without understanding the use cases. Like, why/how
other backends would choose to return different values.

How does using one or the other variable help with that distinction?
When someone uses tags, they often use them with a multitude of
languages. Whether you employ tags-case-fold-search, or an xref-specific
variable Eli suggested to add, that would affect all languages anyway,
right?

We can make completion-ignore-case a safe local variable, so that you
can set it in dir-locals depending on the code base.

No. I believe that completion-ignore-case should always be bound to
the value of tags-case-fold-search when doing a tags completion. If
this is not so then completion is not consistent with the tags search,
which is the bug in question.

From what I could see searching the lisp tree, tags-case-fold-search
is intended for user customization of tags search (and partly carried
over to xref). completion-ignore-case is used for dynamic control of
completion, and is not a sensible variable for user customization.

Yes. It is possible to mix languages even in a single tags table.
Personal preference also plays a role.

I'm not sure that's useful, because the default value of
completion-ignore-case is hardly ever used. For example, even
if ignoring case for tags searches, one would probably not want to
ignore case when completing input for describe-key.
On the other hand, it might well be useful to make
tags-case-fold-search or any xref replacement a safe local variable.
BTW, how might one find the list of safe local variables?

I would expect that you would follow the precedent of find-tag, which
uses tags-case-fold-search and case-fold-search to determine whether
a tags search is case-sensitive or not.
Whether case should be folded during completion seems dependent on the
application; I have never been tempted to change the default value of
completion-ignore-case -- the note on that variable was included because
setting it to non-nil would prevent observing the bug. From a quick look
at the lisp directory completion-ignore-case is typically used by binding
it during a completion.
The info file says:
You can control the case-sensitivity of tags search commands by
customizing the value of the variable ‘tags-case-fold-search’. The
default is to use the same setting as the value of ‘case-fold-search’
(*note Search Case::).
I found it surprising that completion would not follow the tags search
itself in folding case, as I have become used to this useful behavior
over many years of using find-tag.

You are not calling a tags search command, though. You are calling a
backend-agnostic command. Maybe there are inconsistencies there, but I
think they should be resolved in favor of general variables.
In any case, is there a particular reason you customize these vars like
that?
